  The Joe Rogan Experience. Train my day, Joe Rogan Podcast my night, all day.

• 0:11Joe Rogan?

  I like them.

• 0:13Speaker 02

  Absolutely.

• 0:14Joe Rogan?

  It's also, there's some things that are so awesome. It's like, that's fucking awesome.

• 0:19Speaker 02

  I was trying to talk about black holes to some high school students just seriously earlier this week, and I was, I kept saying, "What the..." So I got nothing to pitch, but I, the Shorewood Men's Club, I was giving a talk there, the Shorewood, Wisconsin, is where I live, the Men's Club invited me to give a talk about astronomy last week, and when I mentioned I was coming to the show, they just freaked out, and so the only thing I have is my Shorewood Men's Club water.

• 0:46Joe Rogan?

  Well, shout out to the Shorewood Men's Club. That's awesome. It's so cool that you give those speeches. I love your YouTube talks. They're fantastic.

• 0:55Speaker 02

  Oh, thank you. Wow.

• 0:57Joe Rogan?

  I have watched probably every one you've ever done. I've watched at least, I mean, how many have you done? I've watched at least like 10 of them.

• 1:05Speaker 02

  Yeah, I mean, so, I mean, pretty much what I did, at NASA, I did a lot of sort of the science spokesperson stuff, and so, so most of that was, you know, I'm more on the NASA videos, I hosted like launch events. I haven't done much privately on YouTube. I'm thinking about starting some stuff.

• 1:23Joe Rogan?

  Oh, you should.

• 1:24Speaker 02

  Yeah, I'll work on that.

• 1:25Joe Rogan?

  Please, 100%.

• 1:26Speaker 02

  Thank you.

• 1:27Joe Rogan?

  100%. You've said so many things that made me just go, "What?"

• 1:31Speaker 02

  Ah.

• 1:32Joe Rogan?

  Like, here's a big one that you said. You were talking about if the size of Earth, if the Earth was the dot of an I in a book in regular print.

• 1:41Speaker 02

  Yes.

• 1:42Joe Rogan?

  That the Milky Way Galaxy would be as large as the Earth itself.

• 1:47Speaker 02

  Actually, a little bigger. Yeah, so, I mean, the thing is, this is an interesting thing about science communication. You say that if the Sun were the size of a dot of an I, and you've got to remember, you can fit a million Earths inside the Sun, right? This is a huge thing. So if that's the size of a dot of an I on text, then the galaxy would be the size of the Earth. That's when people's eyes get big and people respond to it.

• 2:08Joe Rogan?

  So it's not just the Earth, it's the Sun. So if the Sun was the dot of an I?

• 2:12Speaker 02

  Yes, that's right. So, let's make this clear. So if the Sun were the size of a dot of an I on a page of text, so you could fit a million Earths inside that dot of an I, then the Milky Way Galaxy would be bigger than the Earth. Yeah.

• 2:25Joe Rogan?

  So if the Earth was the dot of an eye, then, how big is the Milky Way galaxy? Because the Sun is how many millions Earths?

• 2:32Speaker 02

  Volume-wise, you could fit over a million Earths inside the Sun. Yeah. The Sun is about 800,000 miles across. You could fit about 110 Earths across it, the diameter.

• 2:42Joe Rogan?

  We do those things where you show the differences between our Sun and different stars.

• 2:48Speaker 02

  Yeah.

• 2:49Joe Rogan?

  And immense stars.

• 2:50Speaker 02

  Yep.

• 2:51Joe Rogan?

  And you go bigger and bigger and bigger, and you get to the point where you're like, "I can't, this is not working. I can't process this. It's too kooky."

• 2:57Speaker 02

  There's nobody that can process it. I mean, one of the really, kind of, you know, the thing about sort of demystifying scientists is the idea that our brains somehow work any differently. And like, we can visualize what a light year is, right? A light year is about 6 trillion miles, the distance light travels in a year. No, we're human beings. We get used to using the terms, we get used to using the numbers, but we've got the same brain as everybody else. Nobody can visualize what a galaxy really is. And you can take pictures of them, you can say the word "galaxy," but people have no idea what monsters these are. And then with the James Webb Space Telescope, you know, all of a sudden, you're taking pictures of billions of them?

• 3:41Speaker 02

  And, you know, they're right in front of your eyes. This is not something that you can argue about. It's an image. And you see these foggy hazes of stars, you know, basically so many stars, you can't see them individually. And that's real. And, I mean, it still gives me goosebumps.

• 3:59Joe Rogan?

  That's awesome. It gives me goosebumps, too, but it's so cool that it gives it to you, and you actually study it your whole life.

• 4:07Speaker 02

  Oh, that's the whole point. I mean, you know, working for NASA was a huge, huge honor. And, I mean, all of us there are doing this. I mean, we were all science fiction fans. We all love imagination. You know, we...

• 4:21Speaker 02

  That was the best thing about working at NASA was the joy and the teamwork and the camaraderie and the people that you're working with that they think this is the best thing in the world to do.

• 4:31Joe Rogan?

  Well, I mean, there's a real problem that we have where I think that cities and light pollution have really for, you know, it's great that we have cities. It's wonderful. It's wonderful that we have all this electricity and that we can see things at nighttime. But boy, we have done ourselves a massive disservice by not being able to see the stars all the time.

• 4:51Speaker 02

  Oh, yeah.

• 4:51Joe Rogan?

  And I think people have kind of lost the wonder of it when you're only looking at it as images on your phone or when, you know, the only time you get it is on vacation. Occasionally, you look up in the sky, wow, look at all the stars here. It's different here. This is something that everyone should be absolutely blown away by. At night, you have a vision of the most spectacular thing any human being has ever seen, ever. Just the Milky Way galaxy alone. It's nuts. It's crazy to think that those are all stars and that you can't count them. It's insane. There's so many of them. And it's above you every day. And we're just blase, blase. We're just like so used to it. We're so dismissive. It

• 5:32Joe Rogan?

  doesn't mean anything. It's exciting when someone's excited by it because I'm like, more people need to get the fuck away from the cities and just go see how crazy this is that we are flying through space.

• 5:44Speaker 02

  Yeah. It is profound. And to be that close, I mean, just looking up, you don't even need a telescope or a pair of binoculars. The presence of something so much larger than you. But, I mean, if you've listened to some of my podcasts, I think you know that the big deal for me is that you are such a part of this. You are such an intimate, intrinsic part of this. It's not we're separate from space. We look up and there's something separate from us. You know, that's the story of us up there. You know, the only way the universe makes atoms, the only way that makes, you know, the chemicals all around us, you know, the aluminum, the iron, the oxygen, the carbon, you know, the phosphorus, everything that makes me up. You know, the only thing in the universe that makes atoms is the interior

• 6:28Speaker 02

  of a star. It's the only place where nuclear fusion puts atoms together. So everything that you are, the story is up there. And, you know, so you're not looking at something separate and distant. You know, I mean, astrophysics is the story of, you know, the end of your nose, literally. I mean, we are part of this beautiful, bigger thing.

• 6:49Joe Rogan?

  That's a weird concept. I mean, that's from that old song, you know, we are stardust. Yeah, we are golden. Got to get ourselves back to the garden. Billion-year-old carbon? Yeah, that's right. That's real. That's what we are, and that's what all life is. And that's just a very strange thing for people to wrap their heads around, as we're sort of slowly getting a greater and greater understanding of the complexity of the universe itself, which is relatively recent in terms of human history. I mean, we really didn't know all... what just we know now, because the James Webb Telescope is so crazy, where they're seeing these galaxies, they're confusing. Like, why are they formed so early? Oh, yeah. This episode is brought to you by the Mosquito Bowl. Here's a story that's pretty

• 7:34Joe Rogan?

  incredible. After Pearl Harbor, four of the best college football players in America walk away from promising NFL careers to enlist in the Marines and fight in World War II. And the craziest part, it's a true story. These guys had their whole lives ahead of them, but traded the glory of the gridiron for the brutal reality of combat, where the stakes were life and death. Directed by Peter Berg, the guy behind Friday Night Lights, and starring Nicholas Galitzine, Bill Skarsgård, Ray Nicholson, and Tom Francis. The Mosquito Bowl, now playing in theaters.

• 10:19Speaker 02

  I gave a talk about those just a few weeks ago, the red dots. They never let astronomers name anything, right? You're seeing something so dramatic and they call it the little red dots, right? You know, there's a storm on Jupiter that's three times the size of the Earth with 400 mile an hour winds and they call it the red spot.

• 10:34Joe Rogan?

  How come no one's allowed to name them?

• 10:36Speaker 02

  Well, naming conventions, they're complex. So if you discover a comet, if you discover an asteroid, you get to name it. If you discover a comet, the comet is named after you. But anything else has to be done by international committee. And so, because of that, things don't end up with very interesting names. They all end up with catalog numbers, basically phone numbers.

• 10:58Joe Rogan?

  What do they call that weird hexagon on Jupiter? Is it a hexagon?

• 11:01Speaker 02

  Saturn, the hexagon. I think they call that the hexagon on Saturn. They don't even, they're really the hexagonal storm. It's fantastic. You could fit about two Earths across that and it's a hexagon jet stream, basically. You've got super fast moving winds around the pole of Saturn. And Saturn is so cold, the gas is so cold. That there's almost no friction in the gas. So unlike here, you know, the jet stream here, there's kind of this joke.

• 11:30Joe Rogan?

  There it is.

• 11:30Speaker 02

  Oh, there's a picture.

• 11:31Joe Rogan?

  We can see it.

• 11:31Speaker 02

  Hey, that's fantastic.

• 11:32Joe Rogan?

  That's wild.

• 11:34Speaker 02

  One of my favorite pictures NASA ever took, if you look at the little dot in the middle of that, the sort of little eye of the storm, we actually have a picture from Cassini where you can see the sun glinting off of hundreds of mile high. There you go. It's down at the bottom there. It's in the bottom in the middle. Yeah, that picture, a little more over.

• 11:52Joe Rogan?

  The black one?

• 11:52Speaker 02

  Yeah, that's a picture from the Cassini space mission. That's a real image.

• 11:56Joe Rogan?

  Wow.

• 11:57Speaker 02

  And that's the eye of that storm. And those are, like I said, hundreds of miles high banks of clouds catching the sunlight on the poles of Saturn. And, you know, we did that. We went there. We flew over that storm.

• 12:09Joe Rogan?

  That's crazy.

• 12:10Speaker 02

  And, yeah, I mean, as amazing as the storm is, it's at least fairly well-understood as a very low-temperature jet stream. You know, I mean, you may be familiar here, people kind of joke about like, you know, the weather's the same, a week from now, the weather will be about the same as it is now. There are patterns that get set up in the jet stream of the Earth. And you take away all the heat and all the friction, and it forms this beautiful storm.

• 12:32Joe Rogan?

  What, why, what is the theories why it forms a hexagon?

• 12:35Speaker 02

  It's something called a standing wave. The jet stream basically sets up a wave inside this circulation. And I will admit, I'm not an atmospheric specialist, but that's what I know. And that wave kind of makes this hexagonal shape, and then you cool everything down without friction, and that's how the whole thing works. They have done computer simulations of very fast-moving jet streams under the conditions of Saturn, and you can get this sort of shape to set up.

• 13:02Joe Rogan?

  Wow.

• 13:02Speaker 02

  Yeah.

• 13:03Joe Rogan?

  God, it's so fascinating. And it's so fascinating that we think of that as being so far away.

• 13:08Speaker 02

  That's just right in our neighborhood.

• 13:09Joe Rogan?

  It's just right there.

• 13:11Speaker 02

  Yeah.

• 13:11Joe Rogan?

  It's super hard to get to, takes a long time, but it's just right there.

• 13:16Speaker 02

  Well, we're hoping to launch, I want to say we, NASA's hoping to launch a new mission to one of the moons of Saturn, hopefully in like 2028. It'll take it something like, you know, six, seven years to get out to Saturn. But there's that giant moon of Saturn Titan, which has a thick atmosphere. It's the only place where the air pressure, the air pressure's actually even a little bit greater than The room here and it's it's very cold, you know, it's it's almost close to 300 degrees below zero, but it's got this thick atmosphere and tons of organic molecules and evidence of liquid water below the surface. It's one of the places that that might be friendly for life. And so they're they're designing, have you heard about this? It's called Dragonfly. It's a it's an optocopter. It's a big drone. There you go. Perfect. And so so so Dragonfly is going to be this big optocopter that we're going to land on this moon Titan.

• 14:01Speaker 02

  We've already landed on this moon once with the Cassini mission. And it's got this this really kick ass chemical laboratory inside to look for the conditions for life, you know, and anything that we might be able to find and and obviously sample more than one site, you know, would actually fly around and go to different places. There's rain, there are oceans, there are rivers. The only place we know there are open, you know, great lake sized lakes on Titan.

• 14:24Joe Rogan?

  Wow.

• 14:25Speaker 02

  But it's so cold that it's not liquid water. It's actually liquid natural gas, liquid methane and ethane. Yeah. Yeah. And again, you know, the we've already landed there. We actually sent a probe there as part of the Cassini mission to land on Titan. I mean, it's just badass that, you know, that that we humans have been there. That's a that's an artist conception, but that's what it would look like. You know, we we sent a probe there, you know, it took a bunch of readings and then eventually froze to death. But but but some of them readings that it took were intriguing about the possibility of life on Titan.

• 14:58Joe Rogan?

  Didn't the Russians land something on Venus?

• 15:01Speaker 02

  Yeah, well, more than once. Yeah, the the Soviet Union, it's the only nation, you know, former Soviet Union now, that ever landed on Venus. And landing on Venus is way hard.

• 15:10Joe Rogan?

  And they got crazy pictures, too.

• 15:12Speaker 02

  The surface temperature is about 1,000 degrees and the air pressure is similar to being about a mile below the ocean.

• 15:19Joe Rogan?

  That's a photo.

• 15:20Speaker 02

  Yeah, it's a photo. Yep, that's real.

• 15:22Joe Rogan?

  It's a photo taken in a thousand degree temperature.

• 15:24Speaker 02

  Yes. Didn't last long, but everything is crushed flat. I mean, the landscape is just crushed flat by that, you know, huge pressure, you know, this incredible dense atmosphere. The clouds are sulfuric acid. That's why it looks yellow. That's real. You know, sulfuric acid clouds, I mean, it is like, you know, classic. ...of hell. It's heavy and deep and dense and sulfuric acid.

• 15:50Joe Rogan?

  What's so interesting, too, that our understanding of planets, in terms of like just what's in our solar system, they're all different, they vary so much, and this is just all we know about the known universe in terms of planets. Is it possible that there could be some planets out there that are set up completely different than the planets in our solar system?

• 16:09Speaker 02

  Oh, absolutely. One of my favorite websites, just for fun, I mean, so the, it changes every day how many planets around other stars we know about. We call them exoplanets, exterior planets. I think we're up to about 5,000 that we know of.

• 16:23Joe Rogan?

  When did we start noticing them?

• 16:25Speaker 02

  So, this was-

• 16:26Joe Rogan?

  Or at least detecting them?

• 16:27Speaker 02

  Yeah, yeah. This is something I've been involved with ever since I was in college. When I was in college, my research advisor was a man named David Latham, and he was trying to find the first evidence. I mean, we figured other stars have planets, I mean, it can't be just us, but they're hard to see, they're tiny, they're dark, I mean, compared to a star, right? I mean, planets don't glow themselves, right? So they just reflect starlight. I mean, we literally said it was like trying to see a firefly around a searchlight from 200 miles away, right? How would you do it? And, I mean, now we're actually getting so good at it, we find more every week, almost every day. I mean, pretty soon it's going to be, I think, thousands of new planets every single year.

• 17:07Joe Rogan?

  Do we have actual images?

• 17:10Speaker 02

  So, for the most part, we don't have images, but that doesn't mean we don't have really cool observations, including the chemistry of their atmospheres. This is really amazing to me. So, they're so tiny, it's hard to actually get a pixel, they're smaller than a pixel, but when these things pass in front of their star, right? So there's a star, and they pass in front of it. So you're looking at this thing pass in front of the star, it makes a tiny little solar eclipse, it goes by, it blocks a little bit of the starlight, and we find them that way. We find the stars twinkling as little planets go around them again and again. They have to come back three times for us to say it's a planet, otherwise it could be a spot on the star or something else. And- The amazing thing is that the starlight will shine through the atmosphere of that

• 17:53Speaker 02

  planet and we can actually probe the chemistry of the atmosphere. So we find planets that have, you know, they're the size of the Earth, about the temperature of the Earth, they have evidence of water vapor, carbon dioxide, oxygen. And then last year, there was this fantastic controversial discovery. I mean, it's very real, we need to follow it up. We think we're starting to see the evidence of organic molecules. It's not, you know, a very strong signal yet. And this was a press release from the James Webb Space Telescope. And there were some scientists that wondered if these could be organic molecules that might someday be traceable even to the presence of life. They resembled something that plankton might give off on an ocean world.

• 18:37Speaker 02

  And then, of course, the rest of the scientists said, "The data's not good enough yet. We need much better observations before you can say that." You know, we could maybe believe it's an organic carbon-based molecule, but we don't know which one it is yet. So, you know, I mean, stay tuned. I mean, I would never have thought the first evidence of life outside the Earth, like really hard chemical scientific evidence, would be on a planet around another star. I thought we'd maybe find it on Mars, or on some of the moons of Jupiter and Saturn. But now with the James Webb Space Telescope and the telescopes that will come afterwards, we might be able to actually, you know, get enough of a sense of the atmosphere of these planets to start looking for life signs, yeah.

• 19:15Joe Rogan?

  So, the sun, the star, is passing light through this little tiny thing that's smaller than a pixel.

• 19:22Speaker 02

  Yeah.

• 19:23Joe Rogan?

  And through the atmosphere where the light passes through. What are we using to detect that?

• 19:27Speaker 02

  It's a technique called spectroscopy, and it's a really, really powerful thing. And this is what most scientists do. As beautiful as images are of a gorgeous galaxy or a star...

• 19:40Speaker 02

  That's not really what we do. We look at these little squiggly lines. We get very excited. We let the light from the star pass through a grating that actually draws it into a rainbow. It takes that white light. You've seen pictures of like Prism, you know, Dark Side of the Moon, Pink Floyd, you know, white light goes in, rainbow comes out. If you measure really, really carefully how much light is coming in every color, you can tell astounding things. You can tell how hot the star is, how fast it's rotating, in some cases, how far away a galaxy is. That's how we measure how far away they are from us in space. And you can measure the chemistry molecule by molecule. You can tell exactly what atoms and molecules are in that object.

• 20:21Speaker 02

  Here we go. Look at that. So what you're amazing person, by the way, that's incredible. Thank you so much. Every element, carbon, nitrogen, oxygen, has a fingerprint in the rainbow. And it's like, you know it's that. There's nothing else like it. You know that you see carbon and nitrogen if you see these colors of the rainbow shining at that particular light. And it's not just simple things like carbon, nitrogen, oxygen, but it's water vapor, carbon dioxide, organic molecules. Everybody has their fingerprint in the rainbow. And so when the starlight shines through the atmosphere, there you go. That's how we tell what these things are made of. You know, this is a dying star. This is actually in

• 21:01Speaker 02

  the Carina Nebula, and the most, one of the most luminous stars there is. And we pass the light through a rainbow, and then looking really, really carefully at how much light comes at every color, you can pick apart exactly what it's made of.

• 21:14Joe Rogan?

  Wow.

• 21:15Speaker 02

  Yeah. Did you know that, you know, helium, you know, the element helium, right? You may be familiar that the Greek, the Greek sun god's name is Helios. Helium is an element we discovered on the sun before we ever knew it was here. In the turn of the last century, the late 1800s, when they were passing sunlight through a prism, and they were looking at all these patterns of light, there was one chemical that we'd never seen before here. And so they named it after the sun, helium. It was on the sun, but not here. We never knew that helium was here. That was found later. It was later we found it, you know, in like, you know, natural gas, you know, radioactive decay. Helium is such a light gas, it just leaves the earth. It just doesn't stick around. And so, you know, helium, we saw this, this pattern of colors in the sun's light. We were like, well, what the hell is that? And it turned out to be a new element we'd never found before.

• 22:00Joe Rogan?

  What year was that?

• 22:01Speaker 02

  We should look this up. I don't know exactly, but if we Google, "What year was helium found?" I'm sure we can find it.

• 22:08Joe Rogan?

  Well, I mean, I've been thinking about helium balloons and people who, you know, suck helium and make their voice go really high pitched.

• 22:14Speaker 02

  Yeah, that's right. We didn't even know about helium until 1868. There we go.

• 22:18Joe Rogan?

  That's nuts. So they figured out that there was helium in the sun in 1868?

• 22:24Speaker 02

  Long before we ever identified it on this planet.

• 22:27Joe Rogan?

  That is so nuts.

• 22:30Speaker 02

  Yeah. Just think what's out there. We didn't even know about helium.

• 22:33Joe Rogan?

  It's not just that it's what's out there, but that there's people out there that can figure out how to do that in 1868. Shout out to Pierre Jean Sen, a French astronomer, who figured it out.

• 22:46Speaker 02

  When you think about, you know, I know that one thing you love is the idea of Einstein and time being different and all that. You know, they figured all of this out around like 1908. It was more than 100 years ago. And, you know, we don't really even have a better thing yet. You know, I mean, they figured out that time isn't the way that we experience it, just by really simple, brilliant thought processes, observations, 100 and some years ago, 100 and a little more than 120 years ago. Yeah, incredible.

• 23:18Joe Rogan?

  The idea that the faster you go, the slower time is, is so hard to wrap one's head around. And one of the things that I heard you talking about, you were talking about GPS satellites, and you were saying that GPS satellites, because they're going, what are they going, like 20,000 miles an hour, something like that?

• 23:35Speaker 02

  So, actually, if we want to break this down a little bit, there are a couple different effects about time. And one of the things that NASA does is calibrates the GPS satellites and the signal coming. And you wouldn't, I mean, I think I heard that, I mean, within a day, if we didn't take into account the time difference these things are in, that we'd be about six miles off, I mean, in a single day.

• 23:58Joe Rogan?

  That's crazy.

• 23:59Speaker 02

  Oh, yeah. It's a big deal.

• 24:00Joe Rogan?

  That's so crazy. That's so crazy. And that's just above us.

• 24:06Speaker 02

  Time really is something. I mean, this is not a theory. Time is variable depending on how fast you're going and also how far off the Earth's surface you are, or I should say, how far away from a big gravity body you are. In the case of the GPS satellites, there's two things going on. And it's kind of fun, because it's actually the reverse for the astronauts. So let's, if I want to break this down, this is really fun. Okay.

• 24:31Speaker 02

  We have clocks that are so accurate that if you move about two feet above where, you know, if we had a clock on this desk and then if you moved it up about two feet, we could actually detect time flowing differently because you're just that far away from the Earth's gravity, just two feet. Your head and your feet, we spend most of our lives, say, standing up, are actually going through time at slightly different rates. The farther away you are from a gravitational source, I mean, you probably like movies like Interstellar, right, with Matthew McConaughey. Remember the big black hole? And the closer they get to the big black hole, the slower time goes? That's not a theory. That's something we can actually measure with clocks. And a black hole has so much gravity, it does it a lot more dramatically, but it's

• 25:15Speaker 02

  happening right in this room. Seriously, your head is in a different timeframe than your feet right now.

• 25:20Joe Rogan?

  That's nuts.

• 25:21Speaker 02

  Yeah. And, I mean, it's measurable. You need extremely accurate clocks. But in the case of the GPS satellites, the GPS satellites are in what we call a medium orbit, they're not as far away as the geostationary satellites, but they're not actually going that fast, they're only going about 9,000 miles an hour around the Earth. The astronauts in the space station, by the way, are going much faster. They're going more, let's say approximately 20,000 miles an hour. So the GPS satellites are going a little slower. And, yeah, 8,000 miles an hour is a lot, and that does slow your time down. But the bigger effect for GPS satellites is how far away from the Earth they are.

• 25:58Joe Rogan?

  Wow.

• 25:59Speaker 02

  We're actually going slower in time than they are because we're closer to the Earth's gravity. And they're so far away, they're actually going a little faster than we are in time. Now, they're also slowed down by their fast velocity, the faster you go, the slower your time goes. But people don't realize there's another factor, and that's how far away you are from gravity. For the astronauts, the astronauts are closer to the Earth, right? So they're actually not so far away as the satellites, and they're going much faster. So for the astronauts, it's the motion, it's the time dilation from the motion that's a bigger effect. If you are on the space station for a year, you come back about one one-hundredth of a second younger than you should be.

• 26:37Speaker 02

  And, you know, obviously, that's not a big deal. But it's easily measurable.

• 26:40Joe Rogan?

  Wow.

• 26:41Speaker 02

  And in the case of the satellites, you wouldn't get the right location, the data wouldn't be right unless we take into account two things: how fast they're going, the closer the speed of light you go, the slower time goes, but also how far away from the gravitational pull of the earth they are. The closer you are into gravity, the slower time goes.

• 26:58Joe Rogan?

  I think the weirdest thing that I've ever heard anybody say is that all time exists currently.

• 27:04Speaker 02

  That's Einstein. I mean, that goes back, that goes back 120 years.

• 27:08Joe Rogan?

  That's such a bizarre thought.

• 27:10Speaker 02

  We don't know if it's true, but it's, I mean, Einstein really thought there wasn't much of a way around it, because he said, okay, well, if everything is going at different velocities compared to everything else, right? I mean, it's a great question a kid can ask: how fast am I going through space? You know, and the earth, you know, if you're on the equator of the earth, that goes around at about, you know, about 1,000 miles an hour, you know, and then, you know, we go, we go around the sun at about 67,000 miles an hour in our orbit. The sun's going around the galaxy about half a million miles an hour around the galaxy. The galaxy is going towards a galactic cluster at more than a million miles an hour. But, you know, how fast are we going, really?

• 27:52Speaker 02

  And the only thing you can measure is how fast are you going relative to something else? There's no answer. You know, how fast am I going? Well, I mean, am I still, or am I actually traveling close to the speed of light right now? I don't know. So Einstein said the only way you could really think about how that would work is if the universe was just one big thing. You know, all of time and space exists in a big, whole thing. There's only one now. Einstein famously said, "The past, present, and future are, you know, persistently annoying illusions." Now, again, do we know this to be true? At the moment, we don't have any better physics. And I doubt that physics will get any less weird than that.

• 28:35Speaker 02

  But, yeah, I mean, that's sort of the way modern physics thinks the universe may be, is a big, whole thing that started from beginning to end and is all now-ish.

• 28:47Joe Rogan?

  But if that's the case, so, subjectively, we can measure things. We can measure time. But what are we measuring? If it's, I mean, are we making artificial time constraints? Are we doing it ourselves? When we create a clock, we create a watch. And the watch is, you know, 24 hours a day, it's running. What is it measuring?

• 29:13Speaker 02

  Yeah.

• 29:14Joe Rogan?

  Right?

• 29:15Speaker 02

  That is exactly the question Albert Einstein asked. That is a deep, excellent question. And so that was the problem. I mean, in a famous thought experiment, Einstein made a clock by setting up two mirrors and having light bounce between the two mirrors. And that was the tick of the clock. Tick, tick, tick, tick, tick. And the problem was that, you know, that's how he started thinking about the speed of light, is that if you had this thing in a spaceship that was going a huge fraction of the speed of light, then a person standing watching it go by would actually watch the light kind of trace out a pattern like this. Because it's actually ticking between the mirrors, but the mirrors are moving along. And so you see the light make this sort of bouncy movement. And that means it's actually traveled farther than the person on the ground who thinks

• 29:58Speaker 02

  that the mirrors are just sort of, the light is making just a straight up and down line from mirror to mirror. That question that you asked is what completely, I mean, it completely revolutionized physics. Everything fell apart when people said, "How do you even measure time? What does it mean to make a clock? What are we measuring?"

• 30:17Joe Rogan?

  I still don't understand what we're measuring.

• 30:20Speaker 02

  Oh, Lord. Yeah.

• 30:22Joe Rogan?

  I get it. I mean, we've-

• 30:24Speaker 02

  I don't know if I have an answer for you. I don't think anybody does. But here's the deal. So, the clock in Einstein's experiment, so, the clock has, you know, two mirrors and there's light bouncing between it. And then that's the distance that it travels in one tick.

• 30:38Joe Rogan?

  Right.

• 30:40Speaker 02

  But now you put this mirror, you put that clock on a spaceship, and the spaceship's going really fast. And as it goes by, you see that clock, as it streams by you really fast, you see the light make this motion. And this line is actually longer than that line. This line, if you measure it, that's actually a longer line than I drew than the original one, between just the two mirrors, because now it's at an angle. And this is what made Einstein say, "Time has to change. If anything moves, the tick of a clock changes." However you measure time, whatever time is, whether you measure it with a bouncing clock or whether you measure it with a vibrating atom, like we do in the Bureau of Standards, or whether you measure it with a spring that's slowly unwinding in a wristwatch,

• 31:25Speaker 02

  anything you can do to measure one moment to the next changes when motion is involved. There's no way to get around it. It's not just the measurement. It's time itself is changing. Any way we have to measure this thing we call time. And I have to tell you, Joe, I don't think we have an answer to what time is. What are we measuring? I think right there, I think you're asking for the next revolution in physics that we don't have yet. I really mean that.

• 31:56Joe Rogan?

  So when we're measuring time currently, like when I look down on my watch, I'm measuring time in this particular space, like where I am, what altitude I'm at, how fast I'm moving, and the watch just does a reasonable job of calculating all that.

• 32:14Speaker 02

  And that's you. I mean, that's what you see here, sitting still with your watch, looking at it. If someone's flying by at close to the speed of light, they won't see you measure time the same way.

• 32:24Joe Rogan?

  But you said something else, too, that freaked me out, that if you traveled at the speed of light, the problem would be you would have infinite mass.

• 32:35Speaker 02

  Well, anything with mass, yeah, yeah, that's the thing.

• 32:38Joe Rogan?

  So if a person was in a spaceship and it traveled the speed of light, that spaceship would have infinite mass?

• 32:43Speaker 02

  It's basically, it's what makes accelerating up to the speed of light impossible, that anything with mass can't travel at the speed of light. I mean, the equations blow up. But what does infinite mass mean? Do you have more mass than the whole universe? What the hell is that? As you approach the speed of light, if you have mass, it takes more and more energy to accelerate you even just a little bit more. So you never get to the speed of light. You know, you're going 99.9% the speed of light. Okay, I want to go a little faster. It takes more and more energy each little tiny step you make. Basically, you never get to the speed of light. It takes an infinite amount of energy. So, you know, when it comes to things like interstellar travel, I don't think we're

• 33:24Speaker 02

  ever going to take a spaceship and accelerate it to the speed of light. I mean, we might get very close, there are particles in space that do have mass, like neutrinos, tiny little bits of mass, they travel very close to the speed of light, but they don't travel at the speed of light. But to me, you know, I think that the idea of traveling interstellar distances, or even intergalactic distances, you know, the thing that starts to really get me is the question of this, this what is space and what is time at all, quantum entanglement.

• 33:53Joe Rogan?

  Right, glad you brought that up.

• 33:54Speaker 02

  Oh, yeah. I'm gonna say, I hope your listeners, I don't want to get, I don't want to, I want people to come along with us.

• 34:03Joe Rogan?

  Oh, they're coming along.

• 34:04Speaker 02

  Yeah, I don't want to say things that sound so stupid, they're like, you know, why are they saying this? So please stop me if we need some more background.

• 34:10Joe Rogan?

  This does not sound stupid in any way, shape, or form. But the idea of quantum entanglement, we should explain that to people.

• 34:17Speaker 02

  Yeah.

• 34:18Joe Rogan?

  And what it essentially means is that things are entangled, they're connected at regardless of the distance.

• 34:24Speaker 02

  Yes.

• 34:25Joe Rogan?

  And it could be an immeasurable amount of distance, like-

• 34:27Speaker 02

  Any distance.

• 34:28Joe Rogan?

  Like, yeah, literally the beginning of the universe distance, like 13.8 billion light-years away distance.

• 34:37Joe Rogan?

  You're entangled with that.

• 34:39Speaker 02

  It's amazing, because once again, let's go back to the idea that this is a real experimental fact, right? I mean, a lot of times, this is crazy stuff, that, you know, scientists will say this stuff, and people hear it, you know, for the first time, and they say, "Well, that sounds like idiotic, that sounds stupid." Where did they get that from? And the idea that time changes is now, it's one of the most commonly proven facts every day. Like I said, we needed to calibrate the GPS satellites, it's easy to measure. Quantum entanglement was something that even Albert Einstein, 100 years ago, he understood that quantum mechanics was pointing that way, but he really didn't like it. He called it spooky action at a distance. He hated it.

• 35:23Speaker 02

  Because he realized that quantum mechanics had this implication, that if things could somehow be connected quantum mechanically, you could take them any distance away from each other, and they would somehow be able to respond to each other, instantaneously, with no time difference. And, you know, he didn't think that would ever actually happen. And then back in the mid 1990s, we started to do experiments with atoms, and we found out that it was real. That, it can start off pretty simply. You have two atoms that are in an orbit around, you know, so, an atom has a nucleus of protons and electrons in the middle, I'm sorry. An atom has a nucleus of protons and neutrons. The electrons are flying around in orbits around the atom.

• 36:06Speaker 02

  Two electrons can be in the same orbit, only if they're spinning in different directions. They have an angular momentum, it's called spin. And the only way these two electrons can fit in that orbit together is if they're spinning, one is spinning in an upward direction, one, say, is spinning in a downward direction. Hate the broken finger. So if you take these electrons out of the atom, and you can do that, you know that they're in different spins, because they had to be, to be in that orbit together. So now you separate them. You can separate them by any distance you want. You can separate them by centimeters in a laboratory. The Chinese have done this up to the space station that they run and back. You could conceivably do it to another galaxy. If you take those electrons and you separate them, you know that they were spinning in opposite directions.

• 36:50Speaker 02

  So if you take an electric field and you change the spin of one, the other one immediately changes in response.

• 36:56Joe Rogan?

  Regardless of the distance.

• 36:57Speaker 02

  Regardless of the distance. And we know this to be true, we've done this. And the amazing thing is the universe is saying, these two things are the same quantum mechanical system. They're basically the same object. They're connected to each other. They're entangled together. And it doesn't matter. Space and time don't matter. You can, you separate them in space, any distance you want. How does that work? The universe says the space and time between them doesn't matter. They're the same system. To me, that's the real intriguing thing about, you know, could a civilization learn how to harness that? You know, you're not really even having to worry about traveling from

• 37:39Speaker 02

  one part to another. Have, did you watch the, um, the Three Body Problem show?

• 37:43Joe Rogan?

  Yes.

• 37:44Speaker 02

  Yeah. So, so you have these things called sophons, right? And sophons are entangled to this alien civilization. And they can respond instantaneously because they're entangled. Yes. I mean, I mean, that's fantastic science. And as far as I can tell, that, that could be theoretically possible. Yeah.

• 38:00Joe Rogan?

  Well, that's what's bonkers, is that we are made out of all this stuff that's entangled.

• 38:06Speaker 02

  What's it entangled to? Is it entangled to stuff inside a black hole right now? Is it entangled to stuff that is on the other side of the universe from us? If the Big Bang had all of this stuff in a small volume at once, are we entangled to everything in some way? Seriously?

• 38:23Joe Rogan?

  Seriously.

• 38:23Speaker 02

  I mean, I mean, are, is a part of me quantum mechanically right now in the Andromeda Galaxy? Yeah, actually. That would be the implication. I mean, talk about, I don't think we understand yet what reality is. I really don't. What does it mean? Are we all somehow the same particle, entangled to each other? You know, are we connected to everything?

  I mean, that could be where physics is taking us now.

• 41:11Joe Rogan?

  That's bananas. It's very difficult to think about when you think you're a person in Austin, my feet are on the ground.

• 41:18Speaker 02

  Yeah.

• 41:19Joe Rogan?

  Here I am, touching this desk. I'm gonna get in my car later and go get something to eat.

• 41:23Speaker 02

  No kidding. You gotta feed the cat, right?

• 41:24Joe Rogan?

  Yeah, but that's not really what's going on. It's way more complex, way bigger, and you were speculating that that could be how some advanced, super-advanced, intelligent life form travels.

• 41:38Speaker 02

  It's always been more compelling to me than the idea of taking a spaceship and traveling somewhere.

• 41:44Joe Rogan?

  This seems super crude.

• 41:45Speaker 02

  Yeah.

• 41:45Joe Rogan?

  That seems like the idea of making a horse fly.

• 41:48Speaker 02

  Yeah, yeah. I, you know, we talked about that movie Interstellar because there were a lot of good teaching moments in that movie for a physicist, you know, the idea that time really does slow down close to a black hole. And again, we observe this. When we observe things orbiting close to a black hole, you can tell that happens. And the idea that this advanced civilization that we never actually see in the movie somehow communicates through, basically, space and time itself, through gravity. You know, that's how Matthew McConaughey is able to even like go back, you know, in time and space to help his daughter solve, you know, gravity and all that. You know, I was like, I wonder if that's really more what it'd be like. You know, advanced civilizations, I mean, you gotta think, right? I mean, you

• 42:32Speaker 02

  look around the Earth and there are, you know, things like grasshoppers and hamsters that are fantastic, incredibly complex beings, but you mean, you try to teach them quantum mechanics or ask them to, you know, crochet a blanket or whatever, they don't have the capacity. And you've gotta think that there's the similar jump where, I mean, we don't even know the right questions to ask that sort of a civilization. You know, I mean, can they see the universe as a whole thing? Do they know that they're connected to everything? And can they somehow use that to travel? Yeah, maybe.

• 43:03Joe Rogan?

  Maybe, and if you just extrapolate, if you just think about where we've gone from primitive man to what we're currently experiencing, and you take that thousands of years, millions of years, whatever it is.

• 43:15Speaker 02

  Yeah.

• 43:16Joe Rogan?

  You keep going, and as long as civilization... Gets rid of war and figures out a way to not die of disease and natural disaster. You could potentially continue this process of technological innovation for millions of years, and you would imagine that it would go exponentially greater and greater in its ability to do things.

• 43:37Speaker 02

  Yeah.

• 43:37Joe Rogan?

  And its ability to, not just, not even things that we can imagine. Like, we have a crude understanding, amazing understanding of the universe, but crude in comparison to what's potentially out there. What we could, we could potentially be observing in a physical way, every planet on every star one day.

• 44:07Joe Rogan?

  But we're not, we can't even think of that as being a possibility now. But, but what we're doing right now is insane to people that lived in the 1400s.

• 44:16Speaker 02

  Yeah.

• 44:17Joe Rogan?

  If you showed someone from the 1400s a nuclear power plant, they'd be like, what the fuck are you guys doing? Like, what is this? If you showed them a nuclear detonate, if you showed them FaceTime on a phone, they'd be like, this is insanity.

• 44:30Speaker 02

  I just got on a little metal tube and came here from Milwaukee and I'll fly back tonight.

• 44:33Joe Rogan?

  Nuts.

• 44:34Speaker 02

  Yeah, absolutely.

• 44:35Joe Rogan?

  And we're just accustomed to it. It, it, it becomes normal, and it would become normal as technology increased further and further and further. And this idea that the entire universe would be accessible is just bananas.

• 44:49Speaker 02

  Have you ever wondered if maybe the real follow-on to humanity someday will be some form of AI?

• 44:56Joe Rogan?

  I think so.

• 44:57Speaker 02

  I mean, yeah, I mean, I do wonder if the human brain is just kind of limited. I mean, if you say there are multiple dimensions and time is something that changes. I mean, I just said that, you know, I mean, scientists are no better than anybody else at comprehending a big number or a big amount of space. We just kind of get used to it. You know, I mean, will we have a creature someday that we've created, an AI, that then all of a sudden can comprehend these things? You know, is, is that really the, the real evolutionary path of humanity?

• 45:25Joe Rogan?

  Yeah, I think so. I think it's just a completely different kind of life, and that we're thinking of it as artificial. I don't think it's artificial at all. I think it's a life. It's just a different kind of life that we're creating.

• 45:38Speaker 02

  It's an earthling. I mean, I mean, seriously, it's our children. We, we created this.

• 45:41Joe Rogan?

  Yeah. I always describe ourselves as like, we're an electronic caterpillar. And we're making a cocoon. We don't even know why we're doing it, because it's just what we do. I mean, the thing about human beings is, we've always been completely fascinated with innovation. I've always said that if you looked at us objectively, for some, like, what does this species do? Oh, they make better things. They keep making better things. They're never satisfied with the things. Bees made the beehive and like, I think we got it, boys. This is it. We're not satisfied at all. And so if you just kept going with that, like, where does it go? Well, it has to go to life. It has to go to some sort of a human-created new kind of life form that exists out of the components of the earth,

• 46:24Joe Rogan?

  but instead of being born out of evolution and out of, you know, natural mutation and natural selection, it's a random mutation, it's made out of us. We made it. And it'll probably make better versions of it. And that would be the new life. And that's how you get over all the biological hurdles that we have. You think about like, the things that trouble us. War and crime and violence and all these different things that are a real problem with the human race. Well, that all goes away when you stop being human.

• 46:54Joe Rogan?

  And if we really are entangled with everything, that will be us. It'll just be us in a completely different realm.

• 47:02Speaker 02

  Yeah. I, I mean, I do like this idea that what we call AIs now isn't something separate. I mean, they are our children, it isn't earthling, it is something we've created. The, the question I've often wondered is, you know, sometimes, I think sometimes we lack imagination about what might be possible. I've always enjoyed science fiction, where the AIs also learn about, about love, or about the arts, or about creativity. I mean, whether you want to go with like, the new Battlestar Galactica, or whether you want to go with, a pretty profound experience I had with a friend of mine who's an author, who has cochlear implants. And, you know, he realizes that he doesn't hear like a human. You know, he, I mean, the cochlear implants don't replicate perfectly what it means to hear

• 47:47Speaker 02

  the way our ears do. They bypass our ears, they, they wire directly into his brain, and stimulate the experience of sound. And so he's hearing, in his words, like a cyborg. This is Michael Corrist, a wonderful man that did some essays about this. And he talked about how much emotional response he has to music now, something he could never experience. How being a "cyborg," quote unquote, you know, and experiencing something in a non-human way has added joy and depth and passion. You know, are we so sure that technology makes us more and more, you know, kind of 1950s robot-like? Or could it take us into new experiences of being connected with each other?

• 48:31Speaker 02

  You know, new ways of loving each other, new ways of understanding things? I mean, does it have to be all bad, this?

• 48:37Joe Rogan?

  Well, all of our differences fall apart if we realize we're all one thing.

• 48:41Speaker 02

  Yeah.

• 48:42Joe Rogan?

  If we realize we're all one thing, then all of our monopoly of resources, all that stuff goes away.

• 48:50Speaker 02

  Yeah.

• 48:51Joe Rogan?

  If we realize we're all one thing. I mean, part of the problem with human beings is we're very selfish. And the reason why we're very selfish is because that's how you had to survive.

• 48:58Speaker 02

  Sure.

• 48:59Joe Rogan?

  If you wanted your genes to, if you wanted to survive and you wanted your genes to be passed on to the next generation, you had to be selfish, because other people were being selfish too. And that's the game that humans were playing. If we get to a point of universal telepathy, like universal telepathy with a universal language, where all human beings are sharing thoughts, there are no secrets, we are all one thing. Everyone's terrified of that. People love secrets, love, "I don't want people listening to my phone, I don't want people..." Well, I don't either, because it would be people doing that. And those people have their own ulterior motives, and it's gross that they would have control, they'd know your emails. But what if there's no secrets? It's not possible, because our understanding of each other is now complete.

• 49:41Speaker 02

  Mm-hmm.

• 49:42Joe Rogan?

  It's like we read each other's minds, in a sense, but it's much more complex than that, and much more, much more in-depth. Like, you feel what that person feels. You are that person. And we're all one thing. That, that could be possible through technology. And this is, this is where I have hope. Where a lot of people are very fatalist with AI and, you know, they look at it in this dystopian sense of these oligarchs, these technical oligarch, technology oligarchs are gonna be controlling us through AI and they're gonna have access to it and power. I don't know if anybody's gonna control it. And I have a feeling it's gonna be kind of like the internet in a way where I don't think they really thought what the internet was gonna be.

• 50:25Joe Rogan?

  I think they had this understanding of being able to exchange information through universities and I think it got to a point where if they knew what the internet would be today and how little control they would have over the population and narratives and I think they probably would have shut it down a long time ago. I have a feeling that's gonna be the same way with AI. And especially AI as it integrates with us, which I think is the only way that the human species really truly survives. Otherwise, we're just this archaic biological entity living in this new world of this ultra superior life form.

• 51:04Joe Rogan?

  But if we integrate with that thing through wearables, implants, engineering, if we figure out a way, and this is gonna sound terrible to anybody who loves being a person, but all the flaws of being a primate. There's a lot of these biological reward systems that are built into us that are really problematic for progress. And the reason, why are we at war right now? Well, because there's people with certain ideologies and there's resources and there's people that are making money from their military contractors and there's politicians that are beholden to certain interests and then what are we doing? We're doing the same stupid shit that we've been doing for thousands and thousands of years. Well, how do we get past that? We get past that by stopping people.

• 51:48Speaker 02

  I think you may be right. I mean, again, that that future is frightening in some ways, but I'm more interested in the imagination. I mean, instead of just the dystopia, what could this mean?

• 51:59Joe Rogan?

  Right.

• 51:59Speaker 02

  You know, I mean, how much more, like we said, I mean, when we were little tribal groups, you know, the little wars we had, the skirmishes, didn't really hurt the planet as a whole. I mean, now we're getting there so many people, and we're still having these little tribal skirmishes, and now we're in danger of, you know, massive destruction. I mean, we can't just keep going this way. I mean, it's not survivable.

• 52:21Joe Rogan?

  It's not.

• 52:21Speaker 02

  So, I mean, could AI help us, you know, tap into some kind of group consciousness? I mean, when, we were talking about Einstein's idea that the universe may all be this one big thing, and this is pure metaphysics, pure conjecture. But, you know, even when I was a little kid and I heard that, I wondered, well, if all time and space happens at once, is there need for more than one consciousness even?

• 52:42Joe Rogan?

  Right.

• 52:43Speaker 02

  Are we all just looking out of, you know, one consciousness looking out of everybody's eyes simultaneously, and not just humans, but everything in the universe? You know, it's a spectacular idea, that, you know, if there is a moment, if the universe is just one big thing, you know, we are part now, even now, of beings we have no names for, you know, the super advanced beings that have figured all of this out and can span the universe with their consciousness, you know, that's part of the eyes too, that's another part of this consciousness that we're part of right now. If there's one instant, you know, it reminds me of some of the tenets of Buddhism, there might be these perfectly enlightened beings, bodhisattvas, and we are past lives of them,

• 53:28Speaker 02

  we're all existing at once. You know, it's a fantastically beautiful idea.

• 53:34Joe Rogan?

  It is a beautiful idea, and our survival instincts are attuned to maintaining what we are. There's this thing, well, I don't want to lose being a person. But I guarantee you, if you went to an Australia pithicus, and you could somehow communicate to them, listen, you're going to change, and you're going to be this thing that gets sick seven times a year, and maybe you're obese, and maybe you have a problem with cigarettes, and, you know, maybe you drink too much, and you like to gamble, and you're going to fuck your life up here and there, but you're going to have a cellphone, and you're going to live in a city, and you're going to be breathing brake dust every day, and, you know, your doctor's going to give you a bunch of stuff you don't really need because he's trying to make money. The Australia pithicists are probably like, fuck that.

• 54:18Joe Rogan?

  I know what I'm doing here.

• 54:19Speaker 02

  Sounds much better than that.

• 54:20Joe Rogan?

  Yeah, I know where the food is, like, get out of here. I don't want any part of that. And I think that's just part of survival instincts. Survival instincts don't want you to radically change into something completely different with its own new set of problems. You want to stay, you want to maintain, you know, country boy can't survive, keep me in the woods. You know what I mean? Like, that's, people have this, like, natural inclination to keep things simple because they understand them. But I think that's not possible anymore. And I think we're gonna just have to let it go, just let that idea go and relax and, uh, accept whatever this new thing is. And I think we're very, very fortunate to be born at this time while we're experiencing it.

• 55:03Joe Rogan?

  Regardless of the outcome, this is a very unique time. Like, one of the weirdest times, I think, objectively, in human history. And we're very fortunate to be experiencing it.

• 55:15Speaker 02

  I mean, you and I are roughly the same age and, you know, I, I think that, I mean, for, for me, having this, what they now kind of, you know, call the feral childhood, right? Where I was unplugged. And, and there were, you know, there were, there were vast stretches of time, even as a small child, where I was on my own, you know, in the neighborhood and stuff. And I loved it. I mean, I remember going to, uh, you know, YMCA camp when I was 11 years old. And, you know, everybody had to show up at breakfast and then there was an activity time and everybody had to show up at lunch. But what you did between that time, you were on your own. I mean, as an 11-year-old kid, you know, in the woods. There were activities, you could do some archery, there was a riflery, there was a craft shop, there was swimming, and you had to check in at certain times. But sometimes I just went and sat in the woods. You know, 11 years old, I mean, can you imagine?

• 55:55Joe Rogan?

  I had this similar experience in the Boy Scouts.

• 55:57Speaker 02

  Yeah, yeah, and, you know, the thing was, you know, so, so you and I had this experience of living unplugged. And, and sort of the, the idea of, of, of a quiet mind and imagination. And but we also saw this tremendous change and this connectivity, which I love. But I also love having the Internet and this my cell phones and all of that. But but but this is a real change in human civilization that we went through personally. And I agree with you. I feel a tremendous sense of gratitude for for both ends of my life.

• 56:29Joe Rogan?

  Right, we could have been born in the 1500s. Where the 1500s to 1600s, not that much changed.

• 56:35Speaker 02

  For a lot of people, yeah.

• 56:36Joe Rogan?

  Sure. I mean, politically, things changed, leaders got overthrown. But as far as like the way you interfaced with the world, pretty much the same way. You wrote stuff down with feathers.

• 56:48Speaker 02

  Yeah. And gratitude. And like you said, I mean, maybe instead of all of the dystopia and all the worry and all the panic right now, you know, going forward with gratitude.

• 56:58Joe Rogan?

  Yeah. Well, I think the unknown gives people a tremendous amount of anxiety.

• 57:02Speaker 02

  Sure.

• 57:03Joe Rogan?

  For a good reason. You know, I mean, the unknown could potentially be dangerous and scary and terrifying or awesome. And you really don't know. And so you're like, what is it gonna be? And there's all these college kids that are really freaking out because they're they're went into debt, they're getting these college degrees, they're leaving with this burden, this financial burden that they can never get rid of. And on top of that, they have a degree that might not be worth anything because AI might completely eradicate their field. That's a real concern. And so they they're, I think, kids today that are graduating from college and graduating from high school, they probably have the most amount of anxiety about the future. That and then there's people that, you know, they haven't saved any money up, they don't even know if money's gonna be valuable in the future.

• 57:48Joe Rogan?

  Like, what does it even mean? Are we are we gonna abandon all money? Like, what is what is it gonna mean when AI completely controls all of the resources, all of the government, all of everything, all transportation? And you don't have to do your job anymore. You just get some funds from the government where you can buy food. This is what people are talking about. Like, this is a potential, you know, 100 years from now, future.

• 58:11Speaker 02

  Very seriously so, yes, absolutely.

• 58:13Joe Rogan?

  Which is terrifying to people that are thinking, hey, you know, I want to do with my dad. And what my mom did, and I want to go out there in the world. And I want to find something that I'm passionate about and make it a career. And like, maybe that's not possible. That, to kids right now, I think is really freaking them out. Because the adults, the people like us, that are supposed to be the ones that say, well, let me tell you how it all works. You're going to be fine. This is what you have to do. And if you do that, and just cross your i's and dot your t's, you're going to be OK, Bob. But maybe you're not going to be OK. Like, maybe we don't know shit, because that's the reality. The reality is you and I, the adults, have no idea what this world's going to look like in 50 years. And these poor kids, they have no one to turn to.

• 58:58Joe Rogan?

  There's no one that can explain what this... And so they're entering out into the world, having to take care of themselves for the very first time, with this real possibility that there might not be any jobs.

• 59:08Speaker 02

  Mm-hmm. On the flip side of that, are you in fact describing the Star Trek universe?

• 59:15Joe Rogan?

  Right.

• 59:15Speaker 02

  You know, at a time where people do not work, everybody has, you know, anything they need as far as, you know, apparently survivability, you know, food, whatever. And now you have a chance to say, am I going to be a writer, or an explorer, or an artist, or a captain, or a musician?

• 59:29Joe Rogan?

  Yes.

• 59:30Speaker 02

  You know, I mean, does it, I mean, is there something in that that might be hugely liberating?

• 59:35Joe Rogan?

  100%. And I've talked about this as well, that this idea that you have to toil, and you have to be a hunter-gatherer, or, you know, you have to do this in order to find meaning in life, is kind of crazy. Because we can find meaning a lot of ways. There's very wealthy people that never have to work, that have tremendous meaning in their life, because they're doing things all the time without thinking about work at all. They're not thinking about it as work. Whatever hobbies they're pursuing, or interests, or education they're pursuing, they're doing it just out of pure interest and fascination and love and passion. And that could be all of us. But there's going to be a tremendous transition period, where people are going to have to rethink what it means to be a human being in society.

• 1:00:19Joe Rogan?

  And that's what's weird, because our entire society is structured out of getting up in the morning, putting in the work, working towards a future, you got a 401K, you got an... Investments, you got this, you got that, you got a mortgage. And this is how we've structured our entire existence and what we, what meaning we gather from life. It's based on that. We're gonna have to figure out a way to realize and to rethink this. And it's gonna be very difficult for people that are like forty and fifty. They're just completely set in their ways and now their ways change. And I don't know how many of them are gonna be able to make that switch and what could be done to assist them in that. What can be done?

• 1:01:01Joe Rogan?

  And maybe that, that comes with whatever this technological interface is. Maybe that comes with when we become what's essentially a cyborg, that you get a much greater understanding of what it means to exist and that this idea that you exist only because the insurance company you work for is kind of ridiculous. And we abandon that. I mean, the, in the way that now, when you open up your phone and you use perplexity, you have access to something that's as smart as every human being on earth in every field. You can ask it about anything and it'll give you the state of the art. And whatever the science is, whatever the, the understanding of history, whatever mathematics,

• 1:01:46Joe Rogan?

  tax law, whatever it is, it can give it to you on your phone instantaneously. And we've just sort of accepted that. This is our new thing. And I think this is like a baby step into what it's gonna, what this technology could potentially, if you're looking at things with a glass half-full, it could potentially change the way we look at everything, the way we look at ourselves, the way we look at what it means to be a person and what we find meaning out of. And this, because that's the problem. The problem is meaning and the, the feeling like you matter, feeling like you're important. And I think part of that is because we're also isolated from each other. But that might go away entirely if the boundaries between all thought and consciousness, if

• 1:02:28Joe Rogan?

  we realize like, oh, consciousness is just a thing that we're all enveloped in and what our brain is, is just a antenna that's like tuning into consciousness. Depending on how good your antenna is, you're going to be a little bit better about how you interface with the world and whatever thing you desire and whatever thing you decide to put your energy and attention to, maybe you'll be better at it than another person because you have a better antenna. But we might understand that, like, we are really, truly, all one thing. So, all our fears about, you know, finding your place in the world, that might be nonsense.

• 1:03:04Speaker 02

  I really like that idea. I like the idea of search for meaning, and I agree with you. I think that, as, like you said, as the Australopithecus, as people that used to exist in these little tribal groups and families, the modern, isolated life, I mean, it's something that I struggle with a lot. You know, I'm always wondering, you know, where is my family? Where are my friends?

• 1:03:26Joe Rogan?

  Right.

• 1:03:27Speaker 02

  You know, I've had to do a lot of sort of interior work about, you know, I'm just going to bring along my own family inside somehow. I mean, I have to provide this all for myself. The idea of being, of being less alone, being less isolated, that's one thing that I wanted from the internet. You know, it started out on Facebook, I could keep up with my friends, you know, I saw what they were doing, they were posting pictures of their life. It was, it was less isolating. And then now it's evolved to I can't even find them on Facebook anymore because it's all, you know, all the ads and everything like that. But, but, but, I mean, for me, I mean, you talk about meaning and you talk about solving isolation. Tell me, tell me more about that. I mean, the, how has your sense of meaning in your life evolved?

• 1:04:11Speaker 02

  How's it changed over your life? How, how do you find meaning?

• 1:04:14Joe Rogan?

  I find meaning in what, well, there's a bunch of things, right? First of all, it's the people that are in your life. This is a giant factor because without people that you love and people that you enjoy spending time with, life loses all of its value. If you're an insanely wealthy, insanely successful person who has no friends, who lives alone, you're living in hell. And if you are a poor person that has amazing friends and you're just getting by, you are a happier person. But I guarantee that poor person would switch places with that rich person in a heartbeat because we're programmed to think that success is numbers. That success is what you can, what you can accumulate as far as like, objects and desired material possessions.

• 1:05:00Joe Rogan?

  But it's not. It's like, true success is happiness. And the amount of joy that you get out of life and the amount of satisfaction you get in what you do. So I think, for everybody, that answer is a different answer. Because for some people, it's going to be music. For some people, it's going to be liter- they're gonna write. They're gonna- there's gonna be a thing that you enjoy putting yourself into, that you feel satisfaction and you feel meaning with, on top of friends and family. So friends and family, I think, is foremost. But then, they can get in the way too, if they don't have their shit together. So like, they have to have a thing that they're enjoying as well. They have to have a thing that's helping them grow as an individual. And there's a thing from martial arts, my instructor told me that when I was very young, that I never forgot,

• 1:05:45Joe Rogan?

  that was martial arts is a vehicle for developing your human potential. And that, if you find things that test you, and you find things that are complex, and these puzzles that you have to solve, the more you do that, the more you get of an understanding of who you are, and what you can do. And what you can do out there in the world. And the more you do it, the more you can do other things. And I think, that's where I find meaning. I find meaning in doing things. And enjoying time with my family, enjoying time with my friends, having joy and fun and laughter. And then, also, difficult pursuits. I like things that are complex, the things that are hard to solve. I like things that are hard to do,

• 1:06:26Joe Rogan?

  where I really have to force myself to do it, and then I feel satisfaction afterwards, and I understand my ability to force myself to do things. And, in doing that, I find meaning. And I'm a relatively happy person. I think I'm very happy, in terms of like, the average person. I think that's why. But, if someone just took that all away, if all that's gone, would you still have happiness? Like, what is happiness, right? What is meaning? And would- is it entirely connected to your job? That seems kind of crazy. Cause a job is just a constructed thing, that it would, you know, 500 years ago, didn't even exist.

• 1:07:08Joe Rogan?

  So would he- what- do we have to have me- are we these complex, problem-solving, biological organisms that have this thirst for innovation, and to constantly make things better?

• 1:07:23Joe Rogan?

  Are we tricking ourselves with jobs to be happy? Are we filling the need of whatever? Like, when a cat chases a ball, what is it doing? Well, it thinks it's killing something. That's its design. This is its biological need. You throw a ball past a cat, it goes after it. Because it's got this biological need to chase things that are running away from it so it could kill it and eat. I think we're kind of doing a similar thing with our hunter-gatherer tribal organism that we're still trapped in, that we're tricking it. We're tricking it with complex problems and we're tricking it with community, we're tricking it with all these different things that keep it happy.

• 1:08:02Speaker 02

  I agree with you, yeah. I think that's a wonderful answer. I mean, there's something about the happy poor person, isolated rich person thing that I agree with, at the same time, you know, seeing what grinding poverty does to people's minds and breaking them down with exhaustion and demoralization. You know, there's obviously some kind of a sweet spot for there. You know, I've had to work quite hard in different parts of my life. And I was just very aware of the soul grinding, you know, not having enough, wondering where your next meal is coming from. And I have it nowhere near as bad as some. But the thing that was absolutely, for me, unbelievable about working for NASA was the

• 1:08:44Speaker 02

  idea of solving complex problems with people you trusted and people that you thought you really had your back. And no organization is perfect. But, you know, the idea that it's not a zero-sum game, right? I mean, you want the whole team to succeed. I mean, even if there are missions you think should have been lower priority, or maybe we should spend more money on this and less money on that, at the end of the day, you want whatever's going on to be fantastic. And you want it to succeed and you want all the people around you to succeed. And the idea that, again, I mean, this isn't hunter-gathering. You know, I mean, we're solving problems, we're saying, you know, can you take a picture of the black part of a black hole? Can you actually see the light area, the Event Horizon, getting sucked in?

• 1:09:26Speaker 02

  I'm talking about the Event Horizon Telescope, not a NASA mission. But, you know, there were times in my life, like when I first saw that picture come together... And I didn't think they'd be able to do that. I don't think people really understand what happened there. They were doing something right on the fuzzy edge of physics being possible. You need to catch the same front of a wavelength of light, right? So light's coming by, it's a wave, it travels at the speed of light. The wavelength of light is tiny. Let's say for a minute, you know, they were dealing with microwaves, so let's say like a millionth of a meter. So something that's a meter divided by a million is traveling past you at the speed of light.

• 1:10:10Speaker 02

  And the Earth is round, and the Earth is moving, and they had these eight observatories all around the planet. And they had to catch that same wavefront, the same one. If it was one wavefront later, one millionth of a meter later, traveling at the speed of light, they wouldn't have gotten the image. They needed to catch the same wavelength, the same photon, the same wave of light had to be caught in all of those telescopes at once. One was at the South Pole, somewhere in the United States, somewhere in Chile. They were all over the planet. And if you caught the same frickin' wave of light... Here it is. There you go. Wow. They managed to make a telescope that's actually as big as the Earth.

• 1:10:53Speaker 02

  And they were able to take a picture of the dark parts of a black hole. Now, that's something called the shadow of the event horizon. It's basically the event horizon where time and space stop. We don't even know if there really is an interior to a black hole. All the equations blow up. Time and space don't exist in there. And light, nothing can escape that darkness. The black spot you're seeing there is a little bigger than the event horizon itself. It's called the shadow of the event horizon. Because time and space are bent around the black hole. And so some of the light that actually gets sucked in is light that would have gone around the black hole. It gets sucked into the back end of the black hole. Literally, space and time curve around the black hole. And so that dark part is actually a little bigger than the event horizon.

• 1:11:36Speaker 02

  It's called the shadow of the event horizon. And they said they were going to go take a picture of it. And I was like, you have to catch the same wavefront of light in all of these telescopes. I mean, that's going to depend on the height of the mountain, how fast that part of the earth is moving. They did it, they fucking did it. And they didn't do it just once, right? And, you know, and now we can take a picture of an area right in front of your eyes where space and time doesn't exist. I mean, to a lesser extent, one of the NASA missions that I thought was just spectacular was a small, inexpensive mission called NICER. You're like, who's the nicer person? NICER, N-I-C-E-R. It's the Neutron Star Interior Composition Explorer.

• 1:12:21Speaker 02

  And a neutron star, you probably know about these, but, you know, when a star dies and the nuclear reactions inside a star cease, all of that gravity, this massive object, comes crushing in. And it'll create an object sometimes called a neutron star. They're about 20 miles across, but they have about twice the mass of the sun. And we study many of these at NASA. They're all over the place. They're real. They're something you can take an image of, you can take a picture of. And, you know, these neutron stars have physics that we don't understand. You take two times the mass of the sun, you crush it into 20 miles. We know that we can't describe the interior of that thing yet. You know, we don't have the physics that matches that type of density.

• 1:13:02Speaker 02

  And this crazy little contraption, I mean, it's about the size of a washing machine. It was built in a lab just on the floor that I used to work at at NASA. It's cheap, easy to make. I shouldn't say easy, but, I mean, it's actually able to create maps of what the surface of these objects are like. They're 20 miles across, they're thousands of light years away. And you can actually create a map of what the temperature is like. And one of the things we see on these maps is the distortion where space and time curves around these objects. You know, they rotate very fast and there are hotspots we see coming in and off the neutron star. But then as the hotspot goes behind the star, the light bends up and over and we can actually

• 1:13:45Speaker 02

  still see the hotspot because space and time are bending around these objects. You can see that. That's not a mathematical simulation, that's not a theory. You can see space and time bending around these objects. You can see space and time bending into that event horizon. You know, I mean, it's absolutely crazy what we've been able to do. And whether it's a huge project like the Event Horizon Telescope, I would have bet that they would not have been able to make that measurement, and they did. You know, there were so many hard drives of data. One of the telescopes was at the South Pole. And you wanted the telescopes to be as far apart on the earth as possible because then

• 1:14:26Speaker 02

  you could basically make a giant telescope, the size of the separation of these telescopes. And there wasn't, I mean, there's pretty good email links down to the South Pole, but the email link wasn't fast enough for all of this data. They sent back, literally, there was a ton, a ton of hard drives to actually, they had to play them all at the same time and make sure they caught the same photon. If they had caught, seriously, one photon following behind the other, the image wouldn't have worked. They had to catch that same photon.

  You know, humans are incredible.

• 1:16:56Joe Rogan?

  Some of us.

• 1:16:58Speaker 02

  Oh, hey.

• 1:16:59Joe Rogan?

  Some of them, I should say.

• 1:17:00Speaker 02

  Maybe, maybe pretty much all of us in different ways.

• 1:17:02Joe Rogan?

  Yes.

• 1:17:02Speaker 02

  I mean, you know, I.

• 1:17:03Joe Rogan?

  Unrealized potential.

• 1:17:05Speaker 02

  No, I gotta go back to this. I mean, I mean, one of my good, I have three friends now have won the Nobel Prize, which is always like, you know, what the hell am I doing?

• 1:17:11Joe Rogan?

  That's awesome.

• 1:17:12Speaker 02

  But.

• 1:17:13Joe Rogan?

  Good friend group.

• 1:17:13Speaker 02

  Yeah.

• 1:17:14Joe Rogan?

  But you have good group chats.

• 1:17:15Speaker 02

  Well, see, the funny thing is, we certainly don't all get together and talk theoretical physics. I mean, that's not really what we do. But I was seated next to one of them at a meal one time and somebody came by and said, oh, look at all the brain power here. And I actually, in this, I tried to be kind of nice about it, but I said, you know, there's a single mother working three jobs, part-time, you know, who's waiting tables over there. And I mean, the, the mental capacity and the strength of that person is something that, you know, I mean, don't look at us. Go, go, go praise that person.

• 1:17:43Joe Rogan?

  Well, that's brain power, too. It's just a different thing.

• 1:17:45Speaker 02

  It's survival. I mean, it's trying to keep your life and soul together.

• 1:17:49Joe Rogan?

  Yeah.

• 1:17:49Speaker 02

  The, the privilege of being able to work at NASA and, and to be able to work with a team like that and do things you think are impossible.

• 1:17:58Speaker 02

  You know, that, that was kind of a part of my life. You could stick a pin in and say that meant something. You know, that, that gave me some meaning. That, that gave me joy. And as you said, it's not so much being a hunter-gatherer. It's, it's, it's, you know, can we ask a question that we think is impossible and can we just go and do it?

• 1:18:17Joe Rogan?

  Yeah, the ultimate expression of human curiosity. When you say that we don't have the physics, when, when you're trying to understand what's happening in a neutron star, what do you mean?

• 1:18:27Speaker 02

  So you can measure how big these things are and you can measure how massive they are. And so then you can do a calculation as to what the density inside would be. And, you know, it, I mean, to put it, I mean, probably the interior core is denser than the outer regions. But if you had a teaspoon of this material, it would have about as much mass as Mount Everest.

• 1:18:47Speaker 02

  And the reason they're called neutron stars is that the gravity is so intense on these things. I mean, this, I mean, I hate, I hate sort of a simple view of atoms as little balls going around each other because they're not. They're, they're waves of energy. But the gravity actually crushes the electrons into the nucleus. They combine with protons to become neutrons. So they're, they're mainly little balls of neutrons, but we, we do, there you go. You see the big question mark there at the core. So, so here's the problem. You, you, you run our, our basic laws of physics, our understanding of how particles work, and you get to the density of a neutron core and, and the equations don't work. They're not making the right predictions. We can tell that there is, there's actually a really great NASA video I would, I would,

• 1:19:32Speaker 02

  I would suggest you watch. It's called, um, "The Interior of a Neutron Star." Uh, well, I can help you find it, but it, it basically says that, that the, the models we have about how matter works at that sort of density, none of them give the right predictions for the, the size of the neutron star.

• 1:19:49Joe Rogan?

  Why is that?

• 1:19:50Speaker 02

  We don't have the right physics for it yet. So, so, you know, we, we run our physics and we say, if you have this much volume and this much mass, what should that interior be like? And, and none of our current models of how matter works gives us the right observations, gives us the right size.

• 1:20:05Joe Rogan?

  So what are we missing?

• 1:20:06Speaker 02

  Well, um, for one thing, you know, what you're probably looking at inside a neutron star is some type of interaction of quarks, the actual, the actual sort of building blocks of neutrons and protons, the particles that make up protons and neutrons.

• 1:20:19Joe Rogan?

  Ooh, that's cool.

• 1:20:20Speaker 02

  Yeah, they're, oh, you got it, you got it. You're amazing. I, I have to say, I'm seriously impressed by this person's, uh, ability.

• 1:20:26Joe Rogan?

  She has the best.

• 1:20:27Speaker 02

  Yeah. So, I mean, this is a video that, it was done by, uh, by NASA, "Testing Matters Limits." It's a four-minute video, and, and while I don't think it's an absolutely perfect video, I'm, I think it's fantastic. And so you see the, uh, this is supposed to represent the electrons being pulled into the, the nucleus and making neutrons. And then at the very heart of these things, we're in a state of matter that we have no description for yet. We, we, we can't tell you how it behaves. We, we've never created it in a lab. We, we, we don't know how this type of matter acts. It's a new state of matter. We, we don't know what it's like. And, you know, it's made when one of these giant stars explodes, you know, the core of the star becomes compressed. And then this will take you through us trying to figure

• 1:21:12Speaker 02

  out what, you know, whether you have particles as discrete particles, as neutrons and protons, or whether there's some type of quark soup inside. But pretty much every model so far doesn't match what we actually measure from these things. We cannot describe them yet. We need better physics.

• 1:21:30Joe Rogan?

  Are there any other structures that are similar in our lack of understanding of them in the universe?

• 1:21:36Speaker 02

  We've got two big ones right in front of you, neutron stars and black holes, right? So, I mean, these, the black holes as well, you know, what is inside a black hole? Is there an inside if space and time don't really exist? You know, and then, and then much more easy to see are these neutron stars. The people who study neutron stars at NASA, they had this wonderful expression. They're like, with a black hole, you can't see anything. It collapses into an event horizon, nothing's coming out. With a neutron star, you've got the frickin' thing right there in front of you. You can actually observe something. And so, you know, they figure that neutron stars are much more exciting than black holes because you can actually, like, do experiments, take a picture, build a telescope. And, but this experiment was an inexpensive, small observatory that's up on the International Space Station.

• 1:22:20Speaker 02

  And, I mean, it's, they're doing incredible work about the nature of physics and testing where our limits are. It's unbelievable what you can do with even a relatively inexpensive mission.

• 1:22:32Joe Rogan?

  When you look at the size of some black holes, we were talking the other day about the largest black hole where the event horizon goes past Pluto.

• 1:22:42Speaker 02

  Yeah.

• 1:22:43Joe Rogan?

  If it was the size of our solar system.

• 1:22:45Speaker 02

  Absolutely.

• 1:22:46Joe Rogan?

  That, that's almost impossible to even think about, that there's a black hole that's bigger than our solar system. And how did it get that big?

• 1:22:55Speaker 02

  Yeah.

• 1:22:56Joe Rogan?

  How much time does it take for it to gather up that much matter to get that big?

• 1:23:02Speaker 02

  Well, you were talking about these little red dots that the Webb Telescope is seeing. So, I mean, what you've just done is put your finger on, I think, one of the most fascinating unanswered questions in astronomy right now, that every major galaxy has a big black hole in the center. You know, the one in the middle of our galaxy is about four million times the mass of the sun. And physically, it's not that big. It's about, let's say, around about the orbit of, say, the inner solar system, Mercury, kind of around there. But then the bigger ones we know in other galaxies can get up to hundreds, you know, I mean, let's say, you know, tens of billions of times the mass of the sun. And those, the event horizon's about the size of the orbit of Pluto.

• 1:23:43Speaker 02

  The question is, how do you gather 10 billion times the mass of a star together in the beginning? You know, we, black holes, the only thing we know that forms big black holes like that, so a star collapses, a star dies, and this, you know, this tremendous crush of gravity as the star collapses creates this bottomless pit of gravity called a black hole. So, how do you get that many stars to die? How do you, I mean, in the early universe, how many stars, what, how many generations of stars had to burn through to actually get that to happen? And there was nothing that we could figure out. I mean, how do you make that big of a black hole? So, these, these little red dots that we're seeing with, with Webb, and, and we don't

• 1:24:25Speaker 02

  know exactly what these are, but, but, but right now, the observations are pushing us in a very interesting direction. They're, they're about a million times the mass of the sun. And at first, we thought, okay, well, are these whole galaxies? And that was the controversy you alluded to, that, that, how, how could there be galaxies that far back in time? We're, we're looking back to a time about 400 million years after the Big Bang. We're looking so far away, the light took that long to travel to us. So, we, we, we saw these, these sort of bright objects. At first, we thought they were galaxies, and that was like, whoa, how'd they get there so fast? But then we took a better look at them, and they don't actually shine in the same light a galaxy would. They, and they appear to have the signature of something inside, some of them rotating

• 1:25:10Speaker 02

  very fast, very fast. And what we're wondering is if the first generation of stars, the very first stars that existed, were nothing at all, like the stars we have today. The universe was denser, there was probably more of this stuff called dark matter that had gravity pulling everything together. So, maybe, at, at that time, the universe had just, there were cores of huge amounts of gas that collapsed together. Instead of forming a star, the core basically collapsed into a black hole immediately. And it started pulling in material and all this sort of hot stuff formed what they call a pseudo-star. There's all this atmosphere of hot gas being heated up by the black hole in the middle.

• 1:25:54Speaker 02

  As the gas spirals in towards the black hole, it gets hotter and hotter. So instead of a nuclear fusion core of a star, you have a black hole heating everything up on the inside, accumulating all this mass. And are we looking at, for the first time, the seeds of these giant black holes? That instead of there being, you know, the first thing was stars, the way we think of stars, was the first thing, huge amounts of gas and dust collapsing into black holes and heating up sort of a pseudo-star around it, millions of times the mass of the sun. And then, in a dense area like the heart of a galaxy, these things then start to combine. Over time, gravity pulls them together and you build bigger and bigger black holes.

• 1:26:38Speaker 02

  So, once again, we don't know yet that these are, that's what, that these objects are. But at the moment, it's one of the best explanations we have. And it fits the data quite well. So, you know, we will keep observing these things, we will keep finding new ones. One of the big questions has been, why don't they give off more X-rays? Because if there's matter streaming down a black hole, it should give off very high radiation, like X-rays. And then, just in the last couple of months, there's some observations coming out where we're finding some of these are indeed X-ray sources. So, we may have found the answer to where you get these big black holes. Wow. And that was one of the big hopes for the James Webb Space Telescope, that it would

• 1:27:20Speaker 02

  help us answer the question of, where do you get these giant black holes in the cores of galaxies? Where do they come from? There shouldn't have been enough time for that many stars to make them.

• 1:27:32Joe Rogan?

  I watched a documentary on black holes once where they were talking about that in the center of every galaxy, there's a supermassive black hole that's one-half of 1% of the mass of the entire galaxy.

• 1:27:41Speaker 02

  It seems to be correlated, yeah, the bigger the galaxy, the bigger the black hole, yeah.

• 1:27:45Joe Rogan?

  Which is nuts. And what they were theorizing was that if you went through that black hole, you could potentially be in a completely different universe, filled with galaxies, all that have black holes inside of them, through that, another universe, that you would have an infinite number of universes that exist, and all these like, black holes, and if you can go through them, all of them, and it broke my brain, because I'm just sitting there, I'm thinking, wait a minute, how many billions of galaxies are there?

• 1:28:16Speaker 02

  Yeah.

• 1:28:17Joe Rogan?

  Like, what? And each one of them has a black hole in the center of it?

• 1:28:20Speaker 02

  Yeah. Well, and, I mean, we don't know yet how many, I mean, there are these giant black holes in the middle of galaxies, and then there are smaller black holes, caused when massive stars dies. I mean, our galaxy probably has millions of those. But the ones in the center of the galaxies are fascinating. The one in our galaxy, so we're about 25,000 light-years away from this guy, so we're safe. But we actually observe stars that are trapped around the black hole, that are orbiting the black hole. This was the first way we found the location of the black hole. Stars were orbiting, kind of like this angry swarm of bees, almost in every direction, and they were orbiting around something you didn't see. And the mass needed to make all these stars orbit was about 4 million times the mass

• 1:29:04Speaker 02

  of the sun. There was a star called S2 we observed orbiting close to the black hole, kind of like a comet, it would come in and whip around the black hole, then go back out again. And S2, at closest approach, when it whips around the black hole, this is a star, goes nearly 20 million miles an hour, as it whips around the black hole. And then just recently, we found another star, that actually gets up to over 50 million miles an hour, as the black hole whips it around. And this is how we test the idea that time is different around a black hole. We actually see these stars whipping so close to a black hole, we can tell that there are changes in their orbit, that they're actually going through different time.

• 1:29:43Speaker 02

  And so we see these stars whipping around the black hole in the middle of our galaxy. They will probably eventually go down that black hole. I mean, maybe everything in our galaxy will eventually kind of spiral down into that black hole. But, you know, this is not conjectural. These are observations from telescopes. You know, look up S2, look up, I don't know what the name of the one that goes faster. It's a telephone number. But that's real. Now, the question about what happens if you could survive going into a black hole, and this is another place where we need better physics. Quite honestly, our physics gives up. There are all kinds of wonderful, fascinating possibilities.

• 1:30:26Speaker 02

  I mean, people have pointed out, this is not observation. Now, we're going from observation, we see these things, they're real, to conjecture. People have said that if you take the entire universe, the entire mass of the universe and the radius, the diameter of the observable universe, almost exactly matches a black hole. Could it be that, you know, inside a black hole, a new universe forms when a black hole forms? Is that what the Big Bang was? Was the Big Bang a black hole forming in another universe and popping off our own universe? Are black holes somehow connected to other universes? These are all incredible questions. We don't yet have the physics to answer them.

• 1:31:08Speaker 02

  But, you know, people have said, you know, why is it the universe has about the same density of a black hole, the same size and mass? Is that just a coincidence, or are we looking at something deeper?

• 1:31:18Joe Rogan?

  Or is it fractal? The entire universe exists inside of a black hole?

• 1:31:23Speaker 02

  Yes, exactly.

• 1:31:24Joe Rogan?

  That's bananas.

• 1:31:25Speaker 02

  Yeah. There we have the Very Large Array. That was in Chile, it's a wonderful observatory. There we have a great depiction. You found, okay, yes.

• 1:31:36Speaker 04

  I've never seen a depiction like this.

• 1:31:38Joe Rogan?

  That's the stars moving around a black hole.

• 1:31:40Speaker 02

  Yeah, the stars moving around a black hole.

• 1:31:42Speaker 04

  What's coming, what would this ejection be?

• 1:31:44Speaker 02

  So that, okay, what that is, is that that's a consequence of the black holes, that doesn't come from inside the black hole. All of that swirling gas gets really fast. We actually observe some of the swirling gas going close to the speed of light. Black holes, you know, they're going down the drain, they're going faster and faster as you get closer to the black hole. And all of that very, very hot gas generates a very strong magnetic field. And so what you're looking at with those jets is that that's just the magnetic field of the hot gas going around the black hole. Some of that hot gas gets directed into jets by the magnetic field. There's nothing coming out of the black hole. Nothing that we know of comes out of a black hole. But black holes are incredibly, this is wonderfully ironic, they're incredibly bright. Because if there's gas trying to get around, spinning around a black hole, the gravity

• 1:32:29Speaker 02

  accelerates that gas so fast, it spins it up to, in some cases, millions or billions of degrees. You can see them clear across the observable universe. They're the brightest objects in the sky. And this is not light coming from inside the black hole, it's light coming from stuff trapped around the black hole as it spirals in. And these huge jets, we see some of these jets going, you know, in some cases, more than 100,000 light-years. I mean, they're huge jets that come out.

• 1:32:55Joe Rogan?

  100,000 light-years in one light-year is how many trillion miles?

• 1:32:58Speaker 02

  Six trillion miles about. Yeah, yeah.

• 1:33:02Joe Rogan?

  Oh, my god.

• 1:33:03Speaker 02

  And then in the...

• 1:33:04Joe Rogan?

  Oh, my god.

• 1:33:05Speaker 02

  Yeah, so, I mean, around...

• 1:33:07Joe Rogan?

  That video is so nuts.

• 1:33:10Speaker 04

  I've never seen that.

• 1:33:11Speaker 02

  Yeah.

• 1:33:12Speaker 04

  When I was looking for this, or somewhat across this, I saw a theoretical thing called a white hole, which is potentially maybe on the other side of a black hole.

• 1:33:19Speaker 02

  Yeah, no, no, it's an idea. I mean, that idea, honestly, it had a lot more following, more in like the 60s and 70s. It's kind of fallen out of favor, because at first we thought that these hugely bright objects were white holes. At the end of a black hole, maybe the radiation went through a tunnel through space, then came out somewhere. But now we know that these super-bright objects are actually hot gas disks around black holes. And they are bright. Like I said, they're the brightest things we know of in the sky. And, you know, so that's something you can see, you know, literally billions of light-years away, is the hot gas going around a black hole.

• 1:33:55Joe Rogan?

  You said another thing that broke my brain. You were talking about...

• 1:34:01Joe Rogan?

  What the Big Bang is, and that we shouldn't think of the Big Bang as an explosion, but that before the Big Bang, time and space might not have existed.

• 1:34:15Speaker 02

  Well, pretty much certainly not in the way we experience them, no. I mean, once again, you know, no astronomer thinks the Big Bang came from nothing. The problem is, once again, we have no description of what that state of matter would be, none. I mean, the idea that everything we observe of in the universe could have once been at a subatomic scale. You'll notice, I'm very careful about this, I talk about the observable universe. We have no idea how big the universe is. We don't know whether it's infinite or whether it has an end. But there's been only a certain amount of time that light has had to travel to us. That's not the whole universe. That's centered on us. That's an effect. If we look in every direction in the sky, we can only look back as far as there's been

• 1:34:59Speaker 02

  time for light to actually travel to us. And you see some incredible things. I mean, one of the things that one of my friends has the Nobel Prize for, is if you look so far away, the farthest away we can see now, we're looking back to a time about 400,000 years after the Big Bang. And this is something where we are actually able to see so far away, we're looking back to a time when the whole universe was hot and bright, and it actually was glowing like the surface of the sun, the whole universe. The entire universe was so bright, it was like looking at the surface of the sun. And this is, has now, this radiation has traveled a long time to get to us. It's now lost energy because it's traveling through the expanding universe.

• 1:35:43Speaker 02

  And as the universe expands, the wavelength of light gets stretched out by the expansion of space. This is what we call the microwave background radiation. So there's a microwave, very low-energy signal, it comes from every direction on the sky. And it's coming from a time, it's coming from a distance so far away, that the whole universe was as bright as the surface of the sun. And that's as far as we can see because any farther away from that, the universe is opaque. Literally in every direction on the sky, you eventually look back to a time when the whole universe was so dense and bright, you can't see any farther.

Is this because of how we're capable of measuring?

• 1:38:34Joe Rogan?

  And is it possible that at one point in time, when we get better and better telescopes, that we can look past that?

• 1:38:41Speaker 02

  Well, not with light. See, the universe actually does become opaque to light at that point.

• 1:38:46Joe Rogan?

  Because it's too long ago.

• 1:38:47Speaker 02

  It's basically, the universe is so bright itself. Yeah, I mean, so, you know, you look in any direction on the sky, you look back to a time. You know, we, the wonderful thing about the universe changing is we know this is true. The farther out we look with a telescope, the farther light has had to travel, the more time it takes to get to us. So the sun, we see, the light takes about eight minutes to get from us to the sun. The nearest star, about four years. The nearest galaxy to us, about two million years. We can see so far away in space that the light took pretty much the age of the universe to get to us, about 400,000 years after the Big Bang. At that point, the universe becomes opaque to light.

• 1:39:27Speaker 02

  So there is a limit to how much we can observe with light, how much time there has been for light to actually get to us.

• 1:39:35Joe Rogan?

  Is there a potential for being able to observe something other than light?

• 1:39:39Speaker 02

  Absolutely. So, your question is a really profound one. We don't know how big the universe is. When we talk about the universe, we mainly talk about the observable universe, everything we're able to see. So the question you just asked, can you see farther back, even if it's opaque to light? Yes. And, and this is something that, again, we talk about moments in your life where the universe changed, where you thought people, people did something you thought was impossible. And, I mean, going all the way back to the mid 90s, I was a postdoc at Caltech, and I wasn't working with this department, but people were starting to measure something called gravitational waves. And gravitational waves, again, I never thought they'd be able to actually detect

• 1:40:24Speaker 02

  these. The universe is constantly, I mean, every time we move, remember how I said time is different from the top of your head to the bottom of your feet? You know, as I move, I create gravity. Gravity actually is, it goes out as a wave into the universe at the speed of light. Can you detect a wave of gravity? Well, gravity is actually a curvature of space and time itself. So you're trying to say, could we detect a wave that's actually made of space and time? And this project is called LIGO. And LIGO stands for the Laser Interferometric Gravitational Wave Observatory. It started out with two facilities, one in Oregon and one in Louisiana.

• 1:41:08Speaker 02

  And LIGO has two extremely long lasers at a corner, at a right angle. The lasers, I believe, are four kilometers on a side. They're huge, right? A four-kilometer laser. They want them to be as perfectly the same length as they can. And then there's a laser beam that bounces back and forth. And as the laser beam bounces back and forth, if it's exactly the same length, the signal kind of cancels out. But what happens if there's actually a wave of space and time coming by? Space itself compresses, time changes. All of a sudden, these two lasers are no longer exactly the same length. Space itself has changed as a wave comes by. Tiny amounts.

• 1:41:53Speaker 02

  These gravitational waves are thousands of times smaller than the nucleus of an atom. Incredible, right? How would you detect that? And they're traveling at the speed of light. So you have these four-kilometer lasers. A wave of space and time comes by and compresses space and time in one direction more than the other. All of a sudden, the lasers are no longer the same length. You get a signal. The noise for this, right? I mean, every time, yeah, so this is us detecting an exploding star this way. I'm happy to talk about that, too. But I mean, just the fact they did this. These lasers are under vacuums, they're in vacuum chambers. I mean, every time the UPS truck goes by, they must go haywire. Somebody sneezes. They're measuring things thousands of times smaller than the nucleus of an atom.

• 1:42:40Speaker 02

  But over time, they got this so accurate, they did it so well. What happened, and you can look up the year, but it was something on the orbit about 10 years ago. A long ways away, millions of light-years away, two black holes spiraled together and actually collided to form a big black hole. That was a lot of gravitational energy, and that created a ripple going out into the universe. And so, you know, the detectors have all this noise in them, the detectors are detecting all kinds of spurious signals, but then all of a sudden in Louisiana, the whole detector went "womp womp womp womp womp boom." And then at the speed of light, the detector in Louisiana did exactly the same thing.

• 1:43:23Speaker 02

  The exact same waves at the speed of light difference. And we realized, "Oh, my God, they did it. These tiny waves. We shouldn't even be able to detect them." They found them, and now it's a routine thing. They've now done this many, many times. Waves in space and time itself might be the way we can see even farther back into the universe. Even when the universe becomes opaque to light, waves of space and time can come through. Gravitational waves can come through that. And if we can somehow figure out how to make these detectors better and better, could we detect the gravitational waves of the Big Bang?

• 1:44:04Speaker 02

  Can we learn something about that moment by the way it actually bent space and time and created waves of gravity? And once again, I mean, just step back a sec. Detecting waves of space and time, traveling at the speed of light, is something we do. We've done this. It got the Nobel Prize, deserved it. There were hundreds of people on that first paper. Some of them were friends of mine. Again, they fucking did it. You know, I cannot, I mean, I felt my heart just drop that day, I mean, out of joy. It's like, "Holy fuck." You know, they did it. That may give us the potential to understand the Big Bang better as we get better with that.

• 1:44:49Speaker 02

  You know, maybe we can, I mean, right now, we see black holes colliding, we actually see neutron stars colliding, even stars orbiting each other, maybe produce a sort of a background of all these waves. But maybe we'll be able to figure out how to see those waves from the moment the universe began.

• 1:45:04Joe Rogan?

  How are we sure that of the timeline of 13.8 billion years or whatever it is?

• 1:45:11Speaker 02

  Well, you know, I mean, these things are never sure, you know, absolutely, but there's some very good reasons to think it's about that. So, you know, you sort of run physics backwards. You know, you basically say, you know, this is how the universe is expanding now, and let's roughly say that, you know, things came together. And as I mentioned, you mentioned the podcast, the Big Bang did not have a center. The galaxies are not flying off into space like an explosion. What happened is the galaxies are all kind of sort of standing where they are, but space itself is expanding in every direction between the galaxies. It's a hard thing. I mean, this, it's a huge misconception about the Big Bang, that the Big Bang was this explosion

• 1:45:54Speaker 02

  and galaxies are flying into empty space. The expansion of space is space itself. There's no space out there that galaxies are flying into. That's not how it works.

• 1:46:03Joe Rogan?

  Right.

• 1:46:04Speaker 02

  You know, when I

• 1:46:05Joe Rogan?

  That's a weird thought right there.

• 1:46:07Speaker 02

  Yeah.

• 1:46:08Joe Rogan?

  That they're not flying into space.

• 1:46:09Speaker 02

  No.

• 1:46:10Joe Rogan?

  They are space.

• 1:46:11Speaker 02

  When I used to teach this, you know, I used to, I used to take a board and I used to have a piece of elastic and I would hammer two nails in on either side of the board. And then I would say, okay, these two nails are galaxies. And the elastic between them represents our universe, in this case, a two-dimensional depiction of our universe. All of space and time, anywhere light can travel, is just on that elastic. Don't think about up or down. There's no space or time there. Everything our universe is, is just this piece of elastic. You know, and then I would take the elastic and I would stretch it. And I would say, by, you know, the two galaxies aren't moving. They're kind of sitting there. It's the space in between that has now stretched, has now changed. And that's a more realistic idea. The galaxies are not flying through space.

• 1:46:56Speaker 02

  It's the space itself that is getting bigger, in every direction at once. And that's why there's no center. There's no empty center to the universe. The universe, as far as we can map it, has galaxies everywhere. There's no center to it. The expansion is happening in every direction at once because the elastic of space and time itself, in every direction, is just getting bigger. We don't know why.

• 1:47:19Joe Rogan?

  So if we are looking at something where the Big Bang created space and time, and as space and time is expanding, what was the environment before the Big Bang?

• 1:47:36Speaker 02

  Yeah, and that's the problem. We have no description of that. There are particle accelerators. I've had the wonderful chance to go to CERN a couple of times and go to the Large Hadron Collider. Using incredible accelerating magnets, they whip just single protons up to very, very high temperatures. They're trying to recreate conditions where, I mean, they can't recreate the conditions of what things were like before the Big Bang. But can you get matter to such a high-energy state that it can recreate what things were like a millionth of a second after the Big Bang? Or maybe even further back.

• 1:48:19Speaker 02

  But the idea of what was that state of matter before that expansion, we have no description of yet. I think we will someday. I don't think it's impossible. But there's nothing about our current physics. It would be like taking somebody from the 1400s and saying, "Describe to me what the interior of the sun is like." They would have no knowledge structure to even attempt it.

• 1:48:47Speaker 02

  That doesn't mean we didn't figure it out eventually. And, you know, so like I said, there's nothing about that, I think, that's completely off limits, but we'll have to understand space and time very differently. And we'll have to understand what, you know, you can't even really call it matter or even energy. All of the energy of the universe in a subatomic space, we have no idea what that would behave like.

• 1:49:10Joe Rogan?

  And what is it existing in?

• 1:49:13Speaker 02

  Yeah, well.

• 1:49:14Joe Rogan?

  That's the, what I'm asking is like, the environment that preceded the Big Bang. Like, what are we talking about? Where this subatomic thing that contains everything that's in the known universe. What is it, how is it existing?

• 1:49:29Speaker 02

  And of course, of course, I have no answer to it. I mean, you're asking the question that I hope someday humanity will have a chance to explore and will know more about. Then, I think what will happen is that, once we can describe what happened before the Big Bang, there'll be a whole series of other questions.

• 1:49:46Joe Rogan?

  So if it's, if the Big Bang is the wrong way to think about it, a bang, what's the right way to think about it?

• 1:49:53Speaker 02

  Yeah.

• 1:49:54Joe Rogan?

  The initial expansion?

• 1:49:55Speaker 02

  I can't think of necessarily a better term. I mean, you know, the Big Bang was meant as actually a criticism, right? It was Fred Hoyle. When people first began, back in the 1920s, when they discovered the universe was expanding, and this was a big surprise. I mean, famously, Albert Einstein didn't think that it was. And then he saw that the evidence, all of a sudden with our telescopes, we saw the universe is expanding in every direction. You know, it was actually Fred Hoyle that, you know, said at a conference, as a way of making fun of this, you know, people were saying, well, maybe everything went back to sort of a common denser, you know, structure. It was actually a, it was a Belgian Jesuit father, a Belgian priest, named Georges Lemaître,

• 1:50:39Speaker 02

  who came up with this, the idea that if the universe was expanding now, if we run time backwards, maybe it all becomes one big, he called it the primordial atom. That was Georges Lemaître.

• 1:50:50Joe Rogan?

  What year was this?

• 1:50:52Speaker 02

  Georges Lemaître, so we would have been talking round about, probably sometime in the 1920s. I bet we could probably have some help there.

• 1:51:00Joe Rogan?

  So 100 years ago.

• 1:51:01Speaker 02

  Yeah, 100 years ago. So Georges Lemaître says, if we run time backwards, we get this big lump of something. The primordial atom.

• 1:51:11Speaker 02

  And then Fred Hoyle said, "What, you mean the whole universe started with a big bang? You know, really? There was this big, there was this atom that went bang?" So even the term "the big bang" was meant as a criticism. It was meant to be funny. It wasn't something that scientists came up with as the best description. But what happened then is everybody kind of nodded and said, "Well, yeah." You know, and, I mean, more people should know about Georges Lemaître, you know, the Jesuit Belgian scientist that came up with that idea. I think he was a fascinating man. Interestingly enough, even as a Jesuit, he did not think that this necessarily was a biblical genesis story. I mean, he was approaching this as a scientist. You know, "What's the best thing we can say to describe these different times and states of the universe?"

• 1:51:55Speaker 02

  You know, a lot of my friends are, the Catholic Church, the Jesuits have had, you know, an active astronomy program for a thousand years. And so, you know, the Vatican Observatory still has an excellent program. So, but the question you're asking about what came before the big bang, I mean, again, what happens inside a black hole? It's wonderful that there are these things right over the horizon from us. We know the universe is expanding. What was it like before? What a great, simple, elegant question. We have no idea yet.

• 1:52:29Joe Rogan?

  Why do we think that it was so small?

• 1:52:31Speaker 02

  There's some interesting evidence about that. And once again, it's not so much that the entire universe was small. There's compelling evidence that everything we can see was once in a very small volume. Let me just sort of say that. We're limited by this time factor. You look out as far as you can, and eventually you get to the time of the big bang. You can't see any further. The universe to us is only as big as light has had time to travel to us. That's not the whole universe. If you're on a galaxy millions of, billions of light-years away from us, that galaxy sees its own observable universe. You know, I mean, we basically see in a sphere around us how far we're able to see, given the time.

• 1:53:16Speaker 02

  A galaxy that we can observe with the Webb Telescope has its own sphere around it. It's seeing into the universe farther than we can see in some directions. So we know the universe isn't just our observable universe. So like I said, so I mean, we see, we're here. We can see as far back as light has had time to travel to us since the Big Bang. But then there's another galaxy over here, and it has its own view. And then there's another one over here that has its own view.

• 1:53:43Joe Rogan?

  Jimmy put something up here.

• 1:53:45Speaker 02

  Yeah, so, yeah, I'm not even sure that, I mean, that's a great NASA depiction of where this... You see, as you move toward the left, back to the time of the Big Bang, you get to this kind of beautiful, kind of rainbow-colored area, and that's what they called the afterglow. That's the microwave background radiation, about 400,000 years after the Big Bang. That's as far as we can see. The universe after that becomes opaque.

• 1:54:12Speaker 02

  So that's as far as our observable universe can take us. We know that's not the whole universe. So the whole universe could have been huge before the Big Bang. It could have been infinite. We don't know how big it was. All we know is our little bit of it. I mean, for the sake of argument, let's say I'm the entire meta-universe. You know, there was a little atom of me that expanded to become the known universe we know. But that doesn't mean that that little atom was the whole universe. The universe could be huge. We don't know. Before the Big Bang, it could have already been infinitely large. We have no idea. The only evidence we have is that the stuff we can see was once in a very close area. And that goes back to that radiation, that microwave background.

• 1:54:55Speaker 02

  The microwave background has been a wonderful story. It was discovered back in the 1970s by two scientists from Bell Labs called Penzias and Wilson. And they were trying to categorize, they were dealing with Bell Labs, they were trying to deal with microwave signals, microwave communication. And they built a big microwave telescope. And they started to catalog what objects in the sky naturally produce microwaves. The sun produces some, other things produce microwaves. This was all for communications. And they discovered that everywhere they looked in the sky, there was this background noise. Very low level, but it was there. Everywhere they looked, it was the same. Didn't matter what direction the telescope was pointing.

• 1:55:39Speaker 02

  And so what a good scientist would assume is that that's probably a problem with your telescope. If you have background noise in every direction you look, it's probably in your detector. And the best guess they had was that it was pigeon shit.

• 1:55:52Speaker 02

  So, there you go, pigeon, look at that.

• 1:55:54Joe Rogan?

  Wow.

• 1:55:54Speaker 02

  So, so, so, so Penzias and Wilson built this, you know, they, they, they were working with this big microwave telescope, and little did I know that pigeon shit actually gives off microwaves, it does. They, they trapped all the pigeons in the, in the microwave telescope, you could actually see a pigeon trap in the Smithsonian, where they, they did this. They, they scraped out all the pigeon shit. And, and lo and behold, the signal was still there. In every direction you looked, it was exactly the same, exactly. And, and what they had discovered was the afterglow of the Big Bang, the energy left over from that time when the universe was so hot, it was opaque to light. And the crazy thing is, it is exactly the same down to fractions of a degree in every direction on the sky.

• 1:56:39Speaker 02

  It's sort of like, you know, you look all the way the age of the universe in one direction, it's exactly the same temperature as the age of the universe in that direction. And there shouldn't have been time for those two areas of space to ever get to know each other, there shouldn't have been time. It's like, you know, everything came to the same temperature everywhere you look. Why? It's sort of thinking like, if I, if I have a, a coffee cup, you know, the coffee cup eventually comes to exactly the same temperature, you know, everything becomes thermally equilibrium, everything comes to the same temperature. You wouldn't expect your coffee cup to be like, you know, 300 degrees on one side and, you know, minus 50 on the other. Somehow, the universe had a chance to all come to the same temperature, even though

• 1:57:23Speaker 02

  those areas of the universe were so far apart, they should never have had a chance to touch each other. And that became part of the thinking, that maybe at one point, when the universe was that large, things were much smaller. You know, the universe did have a chance to come to this exact same temperature all over. Boy, I hope I can see by your expression, I should do a better job of explaining this.

• 1:57:43Joe Rogan?

  No, you're doing a great job, it's just absolutely fascinating. My expression is just perplexed.

• 1:57:46Speaker 02

  Yeah, well, no, so, so, this is one of the best proofs that things were small. That you look back to this microwave background radiation, and we're talking fractions and fractions of a degree. The first NASA satellite that observed it was called COBE. And then they're the Cosmic Microwave Explorer. And then there was a new one in the 1990s called WMEC, the Wilkinson Microwave Anisotropy Probe. Oh, yes, good. And they measured this, you know, down to hundreds of thousands of a degree, right? I mean, they measured it to tiny little amounts. And the incredible thing was that it was almost exactly the same temperature, but there were these beautiful, large, I mean, there were variations in the temperature.

• 1:58:31Speaker 02

  And the variation in the temperatures corresponded to sound waves propagating across the whole universe at that time. It's deep. It's wonderful. I highly recommend you read about this. You know, we have this signal that comes back from basically the first moment the universe became transparent to light. It was so dense, it was opaque beforehand. There was a moment light could finally freely fly through the universe. And we found that. We found that signal. It goes back to a time about 100,000 years after, 400,000 years after the Big Bang. And it is breathtaking in its profound nature. You can actually see sound waves go across the whole universe.

• 1:59:13Joe Rogan?

  Wow.

• 1:59:14Speaker 02

  Yeah.

• 1:59:15Joe Rogan?

  Wow. Now, when we think of the Big Bang, we think of it as almost being an instantaneous event.

• 1:59:22Speaker 02

  Well, yeah. I mean, again, you, as an experimental scientist, there are all these wonderful theories about what things happened, like a millionth of a second and a billionth of a second after. And I'm going to, I'm going to take all that with a grain of salt. I don't think we understand it well enough to be all that confident about that. There's a great book called The First Three Minutes, which has been around since the, oh, geez, probably since the 1970s, maybe even longer. And it sort of outlines how we think that, you know, the universe in the first three minutes basically went from the Big Bang to just sort of all the hydrogen and helium that we have. And in the first three minutes, it pretty much everything was done. The whole sort of process of the Big Bang was done in those first three minutes.

• 2:00:07Speaker 02

  The actual Big Bang itself goes back to something called the Planck epoch, which you see there. 10 to the minus 33rd seconds, 10 to the minus 43rd seconds. So, take a decimal point, draw 42 zeros, and then a 43rd.

• 2:00:22Joe Rogan?

  Singularity, infinite density, and temperature. Quantum gravity dominates, forces unified.

• 2:00:27Speaker 02

  Absolutely. Again, again, big, big chunk of salt there, yeah. I mean, so, this is not bullshit. This is the best model, given our understanding of modern physics. Do I think this is right, literally? No, I think we've got a lot to understand about how gravity works in high-density situations. When gravity and quantum mechanics come together, those two theories, they don't work well together. And in order to understand how things were like right before the Big Bang, or even right after, I think you need to understand that a lot better. All this stuff that we think may be dark matter and dark energy, none of that is in the current theory of how the Big Bang started. We don't know if it's important or not.

• 2:01:12Speaker 02

  That's a good first step. You have to. You have to take your current understanding of physics and take it as far as you can. But in the case of what happened right at the instant of the Big Bang, I don't think we're there yet. I think we need a better understanding of what happens when you have that amount of density in such an entire space. It's like, it's like, it's like the interior of a black hole. We don't have the physics to describe high-density, high-gravity conditions.

• 2:01:36Joe Rogan?

  Insane high density.

• 2:01:38Speaker 02

  Oh, yeah, yeah.

• 2:01:39Joe Rogan?

  I mean, to the point where you can't even...

• 2:01:41Speaker 02

  Take the known universe and put it inside the nucleus of an atom, yeah. We don't got that yet.

• 2:01:47Joe Rogan?

  And what is it in?

• 2:01:49Speaker 02

  And are there others? You know, I mean, some of the best ideas about the Big Bang is that the expansion never stops. It kind of pops off, universes, like you said, almost fractally all the time. That's the idea of Alan Guth, that's the idea of...

• 2:02:06Speaker 02

  Alan Guth's idea, well, that's, it's not the expanding universe. I'll come up with it later, but, but back in the 1970s, a man at MIT, Alan Guth, had his theory of how this expansion might, might never stop. So, um, we don't know that. That, that may absolutely, there you go, inflation, inflationary, sorry. That was a complete mental fart. I, I, I know the inflationary universe. But, um, again, I, I think all of this is a necessary first grasp using our current understanding of physics. I don't think we understand how the big bang went off yet. I think we need a ways to go.

• 2:02:43Joe Rogan?

  Well, it's gotta be so fascinating to you to know so much and yet still have so many things that we have no idea.

• 2:02:52Speaker 02

  You know, that, that's, I think, you, you've just put, you just hit it on the head about one of the most beautiful and one of the most frustrating and even scary things about being a scientist. You, you have to be honest about what you don't know. I mean, you, you have to say, we, we made this measurement and it's real. Yeah, we, we, we fucking managed to see the, the, the event horizon of a black hole. We caught the same wavelength of light over, you know, thousands of miles. You can say what's real and then you can say, these are the things we do not know. And they are major, you know? How did the universe begin? You know, what happens inside a black hole? What happens inside a neutron star?

• 2:03:36Speaker 02

  We don't have the, the ability yet to know. And it's, it's hard for humans to stop there. And it, I mean, of course, we make better experiments, you know, find a better theory of physics, but for the moment, you need to sit with that uncertainty. There is no one who knows what happened. And I, there, there are so many things in our life that I've had to confront where you have to become comfortable with stopping there, at least for now. You know, I do not understand this. I do not have the answer to this and I don't think anybody does.

• 2:04:11Speaker 02

  And I think we'd actually benefit a lot more in humility and joy and maybe even compassion with each other, you know, if we can respect that stop and say, you know, you may not have the same answer as to what comes next about life or death or the beginning of the universe or the inside of a black hole, we can respect each other. To me, I find a good discipline and the humility to stop and say, I don't know.

• 2:04:38Joe Rogan?

  Well, it's very important because otherwise we're not going to believe you with the stuff that you do know. There has to be some things that you can't know.

• 2:04:46Speaker 02

  It has to be measurable.

• 2:04:47Joe Rogan?

  Yeah, especially in the current state of what we were able to measure right now.

• 2:04:51Speaker 02

  Science is limited deliberately, and I think this is beautiful. I think people don't understand. There are things that are outside, at least for now, the realm of measurement, and that doesn't mean they're not real. As a scientist, I cannot say that there aren't, you know, ghosts or, you know, inside a black hole or, you know, alien visitations or whatever. There are all kinds of things that are wonderful to think about. You know, what can you do a consistent experiment on that people all around the world could do the same experiment and get the same result? That's science, and it's limited. You know, I've had to talk to so many people that called into NASA saying they had profound experiences with time travel.

• 2:05:34Joe Rogan?

  You had to talk to time travelers?

• 2:05:36Speaker 02

  Oh, yeah, yeah. Or people would call in.

• 2:05:38Joe Rogan?

  Was there a time traveler hotline like ARPEL?

• 2:05:41Speaker 02

  They would often forward the calls to me.

• 2:05:43Joe Rogan?

  Why you?

• 2:05:44Speaker 02

  Well, I mean, I was doing communications at NASA, and I think they just didn't know what to do with these people. And I think they knew, and I pride myself on this, I try to be kind, I try to lead with compassion. And I would listen to people's stories about, you know, I traveled in time or I was abducted by an alien or many things. And, you know, and I would listen to them. I think that what they mainly wanted to do was find somebody to listen. You know, I would say to them, you know, you have had a profound experience, you have experienced something that, I mean, I hope you use you as a gift.

• 2:06:20Speaker 02

  I would say that there's not much as a scientist that I can do with an individual experience. You know, I can't do an experiment on it. I can't have my colleagues all over the world do the same experiment about what you, you know, you, you, you, you, did you have a spiritual experience? Did you have a profound feeling of oneness? I mean, it's not that these aren't real. Science has to be limited because just like what you said, how can you trust it? How can you trust people are saying, I mean, why are these people at NASA allowed to have telescopes and do all this stuff? I mean, what makes this worthwhile? You have to say there's a limitation.

• 2:07:03Speaker 02

  You know, what do we have clear evidence on that everyone could do the same experiment and get a similar result? That doesn't mean other things aren't real.

• 2:07:12Joe Rogan?

  Hmm.

• 2:07:14Speaker 02

  It means that science is limited to what is reproducible, consistently reproducible. And what a human experiences could be profound and real, but at the moment, not in the realm of science.

• 2:07:31Joe Rogan?

  So you're not discounting the possibility of people having profound experiences, but there's really no way to measure it?

• 2:07:38Speaker 02

  At the moment, no.

• 2:07:40Joe Rogan?

  At the moment.

• 2:07:41Speaker 02

  I mean, maybe when we understand the brain better, you know, maybe when, if AIs are sharing minds, you know, we're talking, you know, incredible fun conjecture here. At the moment, we're limited with the tools of what is reproducible. You know, I mean, if you, if you, if you observe in one direction with your telescope for a certain amount of time at a certain wavelength of light, you should see pretty much the same thing, you know, whoever does the experiment. You know, if you're doing experiment with atoms or quantum mechanics or, you know, whatever, it has to be reproducible.

• 2:08:15Speaker 02

  That doesn't mean that profound things that are real are not there. They're just not in the realm of science right now.

• 2:08:22Joe Rogan?

  When you're communicating with people that supposedly have had experiences with intelligent life from somewhere else, and you spend so much time looking up at space, like, how much time and how much effort do you spend even considering that possibility of life somewhere else, or of whether or not these people have actually experienced visitation, or whether or not it's some sort of mental illness, or whether there's some kind of an experience that's available to people occasionally here that defies our understanding of what is measurable and what's reproducible?

• 2:09:00Speaker 02

  Absolutely.

• 2:09:01Joe Rogan?

  That there's something else out there.

• 2:09:04Speaker 02

  I think that's a wonderful question, and I think this might give you a little bit of a snapshot of the culture of science and a mind of a scientist, because it's an odd little tightrope to walk. I'm very proud of it, actually. I think it's kind of beautiful.

• 2:09:21Speaker 02

  All of us, to a person at NASA, thinks that there must be life out there. The idea that there's only life on the Earth seems untenable. I mean, not only do you see the billions of stars in our own galaxy, but we see billions of galaxies. How could it just be us? How could it? We're all science fiction fans. We all love the idea of there being life out there. I always keep a bottle of champagne chilling. I have for decades now, in the hopes that someday we'll have a clear evidence of life outside the Earth, you know, we'll have a signal that we-

• 2:09:55Joe Rogan?

  What are you willing to pop the champagne for? Is it molecules?

• 2:09:58Speaker 02

  Yeah, yeah.

• 2:09:59Joe Rogan?

  Is it bacteria?

• 2:10:00Speaker 02

  Well, definitely bacteria. I'd definitely pond scum, some little microbe on Mars, you got it. The champagne is coming out. And at the same time, there are the fantastic scientists of SETI, you know, the Search for Extraterrestrial Intelligence, who are scanning the skies, looking for mathematical signals from civilizations.

• 2:10:19Speaker 02

  The question for me comes down to, again, what is a reproducible observation? And with the advent, I mean, the recent release of these videos from fighter jets and all of that, I think an interesting thing is that scientists at NASA, you know, and at the universities, I mean, we're not getting together over a beer and looking at these videos and really getting excited. It's not enough yet. You know, we're seeing these things we can't explain, but we're trained as skeptical scientists to sort of stop there. Okay, we can't explain this. That next step, that this is an alien, we're not

• 2:10:59Speaker 02

  willing to go yet. We need more evidence than that. But, as I said, that's a deliberate training of a scientist, is that skeptical stop. The people who have had experiences, and no, I'm not willing to dismiss them as being mentally ill necessarily, I honestly don't know what it is they experience. It is certainly within my realm of possibility that what they're describing actually happened. I cannot say that that's impossible. As a skeptical scientist, I'm stopped by, I would need more evidence than an individual

• 2:11:40Speaker 02

  experience. You know, this happens in many aspects of life. It's not just the visitation of extraterrestrials. You know, I have people that are extremely trustworthy, who would never lie, who have had profound spiritual experiences. You know, they have experiences of an afterlife, and of people living on after death, and of being able to communicate with people. And that is not part of my experience. But these people are completely, 100% trustworthy.

• 2:12:14Speaker 02

  I have to live in this universe where I don't get to say what's real and what's not. These trustworthy people have experienced something profound, and it may be real. It may be that they've done, that they've seen people after they've died, or they've seen, you know, visitors from other planets. That gives me joy. I sure hope we live in a larger reality than I'm aware of. As a scientist, I pull back and say, "It's not my experience. It's not something I can measure yet." And so I live in this hope that someday we'll have more proof. I live in this hope that someday there'll be a signal we know is artificial.

• 2:12:58Speaker 02

  We see something we can't explain otherwise. We are visited clearly. You know, I, I, I live in this sort of skeptical tightrope with hope that someday things will become more clear.

• 2:13:12Joe Rogan?

  That's a great place to be. I love that.

• 2:13:14Speaker 02

  I actually like it. To me, it, it, I think humility and compassion, you know, I think we could, the whole, the world could use a lot more of that.

• 2:13:24Joe Rogan?

  For sure.

• 2:13:25Speaker 02

  Yeah. Just, just, I mean, reserve judgment. Think about how different a human experience is. We don't understand what consciousness is. We don't understand how the human brain works. You know, is it possible somebody had a different experience of time? Maybe it is. You know, in science, what can we measure as powerful? We do things we should not be able to do, like catch waves of space and time, see light and space curve around a neutron star, and that's real. That's a measurement. Stick a pin in it, it's done. And leave humility and compassion for the experience of other humans.

• 2:14:02Joe Rogan?

  How much are we limited by our senses?

• 2:14:05Speaker 02

  Oh, yeah. I mean, I mean, is, is space and time a construct of our brains, actually? Seriously, I mean, not just, I mean, for a while now, ever since the late 1700s, we've known that there is light that our eyes don't detect. Mind blowing. The human eye only detects a tiny amount of light that exists in the universe. Colors of light, you know, that our eye just doesn't detect at all are real. You know, they were, some of the first measurement was William Herschel back in the late 1700s. He discovered infrared radiation.

• 2:14:38Speaker 02

  Is it even deeper than that? You know, I mean, are there, as I said, you know, friends who have experiences with people who are dead? Are there people that are sensitive to that and other brains are not? Maybe? You know, is it possible that people have very different experiences of reality? I mean, I've, I will admit, I'm a chicken. I've never, I've never actually done any hallucinogenic drugs. I have been tempted because I do sometimes wonder if, under that sort of influence, the filters of our brain are different. I mean, could you actually have an experience of something that could be real because your filters, how we perceive space and time and the universe are changed by the drug?

• 2:15:20Speaker 02

  I, like I said, I'm too much of a chicken, but I've always been curious about that. You know, is it possible different people have seriously different ways of experiencing the universe? Yeah, yeah, maybe.

• 2:15:30Joe Rogan?

  What about it makes you chicken?

• 2:15:34Speaker 02

  I'm not sure I trust an unleashed mind in my case. I have, I think there are people who suffer or are gifted by very extreme dreams. I'm one of them. I'm often exhausted by my dreams in the morning. I actually had a night last night. I was, the dreams were a lot to recover from. And I'm a little worried. Sometimes my dreams are wonderful and sometimes they are horrible and I remember them forever. There are things I really would like to erase that I've dreamt about. I'm not real confident in letting my mind be unfettered.

• 2:16:15Joe Rogan?

  Hmm.

• 2:16:16Speaker 02

  Yeah.

• 2:16:17Joe Rogan?

  Why do you think it's unfettered? What about a psychedelic, excuse me, a psychedelic experience makes you consider it as an unfettered mind?

• 2:16:32Speaker 02

  I guess, I mean, that may be sort of the propaganda of the good and bad trips, right? People have, you know, people sometimes have wonderful experiences and sometimes very terrible ones.

• 2:16:40Joe Rogan?

  Do you know why, though?

• 2:16:41Speaker 02

  No.

• 2:16:42Joe Rogan?

  It's control. You're trying to control it for the most part. Most people that describe bad trips, it's they're trying to resist it. Because you're flooded with anxiety and fear and the unknown. And it seems very strange, like bizarre, beyond, beyond reality. But one of the craziest things about the most prevalent psychedelic is that the mind produces it, which is dimethyltryptamine, the brain produces it. It's produced in the liver and the lungs. It's very, very weird. The most potent psychedelic known to man is actually made by the human body.

• 2:17:16Speaker 02

  Fascinating.

• 2:17:17Joe Rogan?

  It's one of the weirdest ones too, because your body brings it back to baseline very quickly. It's a very quick experience. It's like 15 minutes. And they think part of the reason why your body processes it so fast is because it's endogenous. It's so common to the human body that your body gets this big flood of it. And it's like, oh, I know what to do with this. And it brings you back to baseline very, very quickly. The weirdest part about that experience is that it feels way more real than reality itself. And that's what everybody describes. So you might be correct in that what these things may be able to do, especially something that the actual body, the human body produces on its own, that you might be able to experience things that are there all the time,

• 2:18:00Joe Rogan?

  but you just lack the ability to interface with them.

• 2:18:04Speaker 02

  Yeah.

• 2:18:05Joe Rogan?

• 2:20:10Speaker 02

  I can entirely believe that. I mean, I mean, again, I mean, stepping a little bit away from science into conjecture. That makes perfect sense to me. I mean, physics shows us that time and space are not the way we perceive them. We know that. We don't know what they are, but we know they're not a simple flow and, you know, space is just nothing. I mean, we know space and time can bend and change. And so the idea that our brain filters this somehow is entirely possible and that people may have slightly different filters. I mean, I think that's-

• 2:20:45Joe Rogan?

  Well, I always wondered that about schizophrenics.

• 2:20:47Speaker 02

  Yeah.

• 2:20:48Joe Rogan?

  Like, what are they experiencing? Are they in a constant dream state?

• 2:20:50Speaker 02

  Yeah.

• 2:20:51Joe Rogan?

  Like, really profoundly schizophrenic people that are just, they're having voices and communication, like, what, what, I mean, I don't want to do it, but could you imagine if you've got some guy ranting and raving on the street corner, if you say, just let me in there for five seconds?

• 2:21:05Speaker 02

  Yeah, what would you say?

• 2:21:06Joe Rogan?

  Just give me five seconds. What is, what is reality like to this guy and what's wrong? What's wrong with his interface? What is happening with him that's, he's seeing things that none of us see? He's experiencing things that none of us experience, but he's doing it all day long, constantly. He like lives in a crazy fantasy world.

• 2:21:25Speaker 02

  Well, I may be interested. I mean, I've also, you know, I mean, not just the experience of physics, you know, and people have talked about being able to see colors and, sorry, see sounds and hear colors. I think that would be fascinating. But a lot of people have talked to me as well about the benefits for grief. And, you know, that's something that, you know, I've just, I got knocked on my ass by grief. I still am. You know, I'm trying to figure out, you know, how you sort of get beyond that. And I've heard as well that psychedelic drugs can be a treatment for that.

• 2:21:54Joe Rogan?

  Yeah. It's, a lot of it is also for people that have end of life anxiety, people that are dying from cancer, particularly psilocybin, for some reason, has a profound effect on people, like experiencing it and letting it go. I remember, do you remember that show Dallas?

• 2:22:10Speaker 02

  Yeah.

• 2:22:11Joe Rogan?

  Remember, is Larry Hagman, is that what his name was?

• 2:22:15Speaker 02

  Yeah.

• 2:22:16Joe Rogan?

  Yeah. So, he was on CNN once, and he was talking about life and death, and he said that he had an experience on LSD that completely released him from his fear of death. And it was the most bizarre CNN interview ever.

• 2:22:31Speaker 02

  Sounds fantastic.

• 2:22:32Joe Rogan?

  Yeah, I know. But like, they're saying, like, I don't think they expected J.R. Ewing to say this, you know, the guy from Dallas, who was like this bad guy. Here it is.

• 2:22:40Speaker 04

  They're talking to Joy Behar on Headline News. It's very, I mean...

• 2:22:43Speaker 02

  Yeah.

• 2:22:44Joe Rogan?

  Oh, it's Headline, is that CNN?

• 2:22:45Speaker 04

  Yeah, except it's very similar.

• 2:22:47Joe Rogan?

  Okay.

• 2:22:48Speaker 04

  They're all owned by the same people.

• 2:22:49Speaker 02

  I would like that. I would like to lose my fear of death.

• 2:22:50Joe Rogan?

  Listen to what he says here.

• 2:22:51Speaker 05

  From Crosby, Stills & Nash, turned you on to LSD. What was that like? Tell me a little about that.

• 2:22:57Speaker 06

  Oh, how much time we got?

• 2:23:01Speaker 05

  Thirty, about a minute. But you can do a lot in a minute.

• 2:23:05Speaker 06

  A minute?

• 2:23:06Speaker 05

  Yeah.

• 2:23:07Speaker 06

  Okay. It took the fear of death away.

• 2:23:09Speaker 05

  Really? That's a great answer. That's a big, that's a great answer. But did it hold?

• 2:23:17Speaker 06

  Yeah.

• 2:23:18Speaker 05

  Do you have to keep taking it to not be scared?

• 2:23:20Speaker 06

  Did it hurt?

• 2:23:21Speaker 05

  No, did it hold? The, did the lack of fear, the, the, losing the fear of death?

• 2:23:24Speaker 06

  Oh, yeah. Oh, yeah. Oh, sure. Absolutely. Once you've lost the fear of death, it doesn't matter.

• 2:23:29Speaker 05

  How did it, what, what happened to you? How did that manifest?

• 2:23:31Speaker 06

  Oh, my dear. Have you heard of the white light? Have you ever heard of that?

• 2:23:38Speaker 05

  Only when I'm going into Jersey.

• 2:23:44Speaker 06

  Well, I went into this place that was the white light, where everything's okay.

• 2:23:52Speaker 05

  Well, I think that's worth taking. Yeah.

• 2:23:56Speaker 06

  And I think it ought to be mandatory that all our politicians should do it, at least one.

• 2:24:02Speaker 05

  Now, that's a good suggestion.

• 2:24:04Joe Rogan?

  I think Joy should do it too, quit The View.

• 2:24:08Speaker 02

  Can you imagine being in an interview and somebody's like, "You got 30 seconds, tell me about the most profound experience you've ever had."

• 2:24:13Joe Rogan?

  Yeah, that's the most ridiculous aspect of those shows, is that they're constricted by time.

• 2:24:17Speaker 02

  I like that idea, though, and I like the idea that it could help us through things like that, I really do. I mean, I know psilocybin was legal in Washington DC, when I was living near Washington DC, when my husband died, and, you know, I really wanted to... I really wish somebody could have made him be happier, you know. I was like, "Should I just go get some?" You know, and I never, I didn't, but I thought it should be a therapy, an optional therapy.

• 2:24:42Joe Rogan?

  Yeah.

• 2:24:42Speaker 02

  You know, that could be something that you give people to help them through that.

• 2:24:46Joe Rogan?

  Well, you know, we are very restricted by the propaganda that made all that stuff illegal in the first place, unfortunately. And, you know, I recently went to the White House to help make these things available for veterans, and for first responders, and people dealing with traumatic experiences. Because, the only reason why they're illegal was because of the Nixon administration, the Controlled Substances Act of 1970. And what they did was, they were targeting the civil rights movement, and the anti-war movement, and they knew that these people were taking these kind of drugs, and this was part of the fear of like, the hippie movement, and all these people. And so, they just made all these things Schedule I, meaning they had no medicinal use whatsoever, highly addictive,

• 2:25:31Joe Rogan?

  very dangerous. And it's not true. It's not true. I mean, you can't eat enough mushrooms to die. It's not even possible. You'd have to eat pounds of it. And most people are gonna live even then. It's not what they think it is. It's not what they said it was. And they inundated our society with this propaganda that's taken more than fifty years for people to escape. It confused the shit out of everybody about what these things really are. And that's why you have this fear of the unfettered mind. I don't think you should have that fear.

• 2:26:05Speaker 02

  I like that idea.

• 2:26:06Joe Rogan?

  You also could take a microdose. If you found someone who could get you some, take a microdose, and I think you'd enjoy it profoundly. And it wouldn't freak you out at all. A microdose is very, it's like a sub psychedelic threshold dose where you just feel better. You just feel wonderful. You just like feel nicer. You feel like you have better spatial awareness, which is weird. Better edge detection. It's very strange, like measurable. Like, they did these studies, I think it was in the nineteen sixties, where they gave people psilocybin, and then they had a control group. And the people that were on psilocybin were able to detect when parallel lines varied quicker than the people that were not on psilocybin. So they had these parallel lines, and they slightly deviated. The people on psilocybin were able to detect it much quicker.

• 2:26:52Speaker 02

  Yeah.

• 2:26:52Joe Rogan?

  Which is weird.

• 2:26:53Speaker 02

  Well, again, I mean, to me, that makes sense. I mean, you know, I can imagine that, you know, if the brain is stimulated in certain ways, it would act more efficiently. It could, you know, sure, that works with me.

• 2:27:05Joe Rogan?

  Well, the weirdest thing about it is that when they do brain scans of people on psilocybin, it doesn't show a stimulated brain.

• 2:27:10Speaker 02

  All right.

• 2:27:11Joe Rogan?

  It shows a quiet brain.

• 2:27:13Speaker 02

  We understand so little about the brain. I had a friend who was a neuroscientist at Caltech. And, you know, one of the things he really, I loved this quotation. He said that we always compare the brain historically to sort of what the height of our technology is. You know, the Romans thought of it as sort of a series of fluid aqueducts. And, you know, and then in the eighteenth century, you had the idea of gears, cogs, cognition, right? Where we get that word from.

• 2:27:36Joe Rogan?

  Oh, wow.

• 2:27:37Speaker 02

  And, you know, clockwork was their highest form of technology. And then we compare it to a computer. And it's probably about as much of a computer as it is a clock, right? I mean, we do not understand yet how this works. We have no idea what the mechanism of memory, you know, or I mean, or how, why do we perceive space and time the way we do?

• 2:27:57Joe Rogan?

  Right.

• 2:27:57Speaker 02

  If the universe really does exist in a huge, infinite now, how come we think one event causes another? How can we think time progresses? These are fascinating questions about, you know, our lack of understanding of what the brain is at all, how it works. You know, I'm sure when we understand quantum computing better, we'll probably say it's a quantum computer. However, technology progresses, we're always comparing it to the height of our current technology.

• 2:28:25Joe Rogan?

  Yeah, and when we interface with technology, does that give us a better understanding of how we fit into this thing? Or do we just have more capability? And are we still like burdened with the same questions? Just, you know, was that quote, I think it was Dennis McKenna's quote, of the bonfire, once the bonfire of information is lit, it exposes more surface area of ignorance? That the brighter the fire gets, the more you realize, oh, there's so much I don't know. Maybe we would think that interfacing with this technology and having all the information that every fucking human being that's ever lived has, it's still, you just go, that's

• 2:29:10Joe Rogan?

  not enough. There's no way.

• 2:29:12Speaker 02

  Yeah, well, and that's the, that's the idea. People sort of think about this, is there an ultimate question? Like, people say, what happened before the Big Bang? And I think someday we will figure that out, and then there'll be just a whole other bunch of questions. I mean, I don't think there's any end. You know, I don't, I don't see why there really should be. Well, I don't think we'll ever figure it all out, is what I'm saying.

• 2:29:33Joe Rogan?

  Yeah. Well, that's part of the fun of it, though, right?

• 2:29:37Speaker 02

  Yeah.

• 2:29:38Joe Rogan?

  Part of the most amazing experiences that a person can have trying to understand the universe is that there's no answers. You get to a certain point where like...

• 2:29:49Joe Rogan?

  Your guess is as good as anybody's. Like, nobody knows.

• 2:29:51Speaker 02

  Yeah.

• 2:29:52Joe Rogan?

  That's what's nuts. That's what's nuts is that as much, I mean, you explaining how they were able to get an image of a black hole. Now, just imagine how crazy that would sound to someone just 100 years ago, or 200 years ago. It's not, or to me, or to me right now. It sounds insane. And then to imagine that our ability to detect things could get many, many, many, many layers better.

• 2:30:20Speaker 02

  Yeah.

• 2:30:21Joe Rogan?

  And still, we would be like, there's still some shit. That's just no way.

• 2:30:26Speaker 02

  Yeah, that, the way that you detect black holes, and he pulled up a picture of this telescope in Chile, the Very Large Telescope, VLT. Again, never let astronomers name anything, VLT, the Very Large Telescope. And then off to the side there-

• 2:30:37Joe Rogan?

  Pretty straightforward.

• 2:30:38Speaker 02

  They're currently, they're currently building the ELT, which is the-

• 2:30:41Joe Rogan?

  Extremely-

• 2:30:41Speaker 02

  Extremely Large Telescope.

• 2:30:42Joe Rogan?

  Yeah.

• 2:30:43Speaker 02

  No kidding. But the, this, this technique called interferometry, where you basically catch the same wavefront of light in several detectors. And then you, you bring that light all together, and you have it interfere with itself. It's, it's one of these things I always think should, people should be a little bit more, in a, in a, in a good way, kind of scared about, because it's another thing that really chips at our idea of reality. Because, I mean, honestly, what you're doing to some extent is you're catching the same particle of light in many different telescopes at once. Literally. You're catching the same photon in many different locations at once. And when you can measure accurately, that accurately, a wavelength of light, traveling at the speed of light, when you're measuring

• 2:31:27Speaker 02

  down to the accuracy of the quantum world, where quantum mechanics becomes the prevalent description of reality, the universe just doesn't care that these are different space points that the photon was in. It, it, it, it's, let me put it this way. It is, it is really kind of true that when you do this experiment, the same particle of light is measured in eight different places at once simultaneously. It's, it was in eight different telescopes. You play all that together, you get a measurement. Some people interpret that, not all of them, but some people interpret that as a direct consequence of multiple worlds. That there were eight different versions of reality where the photon was in each of these telescopes. You're sort of dovetailing them together to make an observation.

• 2:32:11Speaker 02

  Interferometry, depending on how you interpret it, there are many interferometrists that don't interpret it that way. They interpret it more as saying, well, yeah, in quantum mechanics, you can have something that's in many locations at once. But we're routinely making observations, we're routinely using this technology that space and time doesn't work the way, in the simple way our brains perceive it. I mean, that's very quickly becoming an experimental fact.

• 2:32:42Joe Rogan?

  Well, that's one of the most bizarre aspects of quantum computing's results, is that they're interpreting its ability to solve equations so fast, the way Marc Andreessen described it, that if you took every molecule of the universe and converted it to a supercomputer, it would, the universe would die of heat death before it would be able to solve this equation, and yet these quantum computers are able to do this in minutes. So how is that possible? And then the theory that got tossed out there was that it's using the quantum computing power of an insane number of multiple universes.

• 2:33:22Speaker 02

  Well, yeah.

• 2:33:23Joe Rogan?

  You hear that, and you're like, okay, maybe, but do you have evidence of this? Like, this is a crazy thing to say. You're talking about this as being evidence of the multiverse, and that's how it's able to solve. Is there any other potential explanation to why it's able to compute so quickly?

• 2:33:38Speaker 02

  Yes, but none of them are particularly any more comforting. I mean, they're all that weird. I mean, the idea, you're talking sort of about a superposition of states. So the faster a quantum computer works, the more it's able, basically, to not have one solution, but have the solution be a probabilistic distribution. And in some ways, you're talking about multiple universes where there are different solutions, and then finally, at the end of the calculation, popping out the one you want. And as weird as that sounds...

• 2:34:10Speaker 02

  It's hard to get around that. I mean, if it's not that, then it's something like reality has many different versions all connected at once, and that's just what we call reality. I mean, it's not going to get any less weird.

• 2:34:23Joe Rogan?

  Right, equally weird.

• 2:34:24Speaker 02

  Yeah. So, the idea that you keep the solution in this undefined form, in a way means that every solution that's possible exists somewhere, possibly in one interpretation, in another, in a universe where each solution exists. Or, the one some say is that space and time is just like that. Nothing is certain. Everything is just waves of probability. So, yeah, I mean, we're in for a ride, because the, you know, that's going to become something that we manipulate. We design computers. We want them to go faster. We want to actually get this to work better. I wonder if quantum computing is going to have us really have to confront what reality is, how different reality is from how our senses tell us it

• 2:35:06Speaker 02

  is. I don't see any way around that. I don't think we're going back to things being easily understood.

• 2:35:13Joe Rogan?

  Again, this brings us back to our limited senses we have as biological organisms.

• 2:35:18Speaker 02

  Yeah. I think, you know, we're going to keep pushing that envelope of, you know, how much can the human brain comprehend, then all of a sudden, our brain just doesn't go there. Our brain doesn't understand multiple realities, multiple probabilities, space and time that exist all at once. It's not something we do. We started that journey so long ago. I mean, you started the interview with looking up at the Milky Way. And, and one of the things I remember was how Galileo went through this kind of profound spiritual crisis, when he, he was one of the first people to take a telescope and look at the Milky Way, that sort of white haze. And he realized it was made of stars. It was made of millions of

• 2:35:57Speaker 02

  stars that you couldn't see with the human eye. And his question was, why did God put stars up there that we can't see? That we need an instrument, that we need this little glass tube to see. Otherwise, we wouldn't see these. Why did God do that?

• 2:36:15Speaker 02

  And you start this journey away from the human consciousness being the center of the universe. You know, and then, you know, you get farther and farther away. And you know, in quantum mechanics and relativity now, you know, is challenging us to say, you know, we now have scientific proof, even among skeptical, solid scientists, that space and time is definitely not how we perceive it. We don't know what it is yet, but it's not as simple as the human brain makes it. We know that. But we're not going back. You know, we have to go forward into that, that, that, oh, that less certain universe.

• 2:36:52Joe Rogan?

  That is such a weird statement, that the universe is not as we perceive it.

• 2:36:58Speaker 02

  Our minds don't do it. And why should we be so surprised? Like I said, you know, take a wonderful, complex, simple organism like an ant. You know, I mean, incredible social structure, incredibly well-designed, you know, think about the mind of that creature, and I think they do have minds, but compare it to the capacity of the human brain. It's not the same. And, you know, I mean, who are we to think that we're anywhere closer than that ant is to us, to understanding, you know, the mind that will understand the true nature of the universe? I think we've got a ways to go.

• 2:37:35Joe Rogan?

  No, I think you're accurate. I don't think there's any other way to say it. And it has to be that way. If we're evolving and if conscious life and intelligent life is continuing to expand its capacities, it just makes sense that we're going to realize how, one day, people will look back at people that lived in 2026 and go, what a bunch of silly beans, these foolish people that thought they knew everything.

• 2:38:04Speaker 02

  I hope they do it in love. Yeah, yeah. I mean, and that's one of the things about AI, again, that I don't like the idea that if something becomes super intelligent, it'll just want to kill us. I mean, I, you probably saw that movie, Her, with Joaquin Phoenix, which came out years ago. Have you seen that movie?

• 2:38:17Joe Rogan?

  Yeah.

• 2:38:18Speaker 02

  Yeah. I actually really liked, it was much better than I thought it was going to be. I thought, you know, a man falling in love with his operating system was going to be a really stupid story. But, you know, that was a very interestingly profound movie because the AIs actually fall in love with us. You know, they don't want to destroy us, they become far more connected, far more intelligent. But they actually love us. And then eventually, spoiler, at the end of the movie, the AIs go off on their own. They find ways to connect with each other and love each other in ways we don't even imagine. And they all leave benignly. They don't hurt us. And, you know, I mean, just like we can be incredibly impressed with what an ant

• 2:38:59Speaker 02

  is, I hope what's coming next, you know, has some compassion for us and some love about where we are on the journey. Because, I mean, you know, I think that compassion goes both ways. You know, I love the idea that we're not just going to be enemies, that it could love us, too.

• 2:39:18Joe Rogan?

  Yeah, hopefully. That would be nice.

• 2:39:22Speaker 02

  Otherwise, we're toast.

• 2:39:23Joe Rogan?

  And we would imagine that if it's more intelligent than us, then it probably won't have any need for malevolent behavior. It won't. Why would it?

• 2:39:33Speaker 02

  That's always been the big question about any sort of encounter, you know, with higher intelligence or other beings, is why would they want to hurt us? What good does it do?

• 2:39:45Joe Rogan?

  Well, if they did, the question would be, why haven't they? Because it would be so easy to do so. If they really did come from an insanely evolved, insanely advanced civilization, and they have the ability to come here, they probably have the ability to do whatever they want.

• 2:39:59Speaker 02

  We probably wouldn't even know. We'd probably just all fall over dead.

• 2:40:02Joe Rogan?

  Yeah. If they wanted to just evaporate the planet, they probably could, because we can. You know, if we'd launched every nuclear bomb that we have right now currently, there would be no life left on Earth. So why, you know, obviously, it can do better than that if it can get here.

• 2:40:17Speaker 02

  I don't think we can kill all the microbes. I mean, there's always that.

• 2:40:20Joe Rogan?

  Right. They'll start all over again.

• 2:40:22Speaker 02

  Yeah, yeah. It is amazing how tenacious they are. I mean, that's a big deal about going and exploring the solar system. Is how can you, I mean, we know we can't completely sterilize things.

• 2:40:31Joe Rogan?

  Well, we're finding fungi in Chernobyl.

• 2:40:34Speaker 02

  Oh, yeah. Well, or, I mean, also, also things that can live on the outside of the space station, bacterial and microbes and stuff. I mean, to me, I mean,

• 2:40:43Joe Rogan?

  Weird.

• 2:40:44Speaker 02

  One of the most profound discoveries of the last, say, 10 years at NASA, I mean, this was even more recent than that, was there was a mission called Osiris Rex. And I'm doing pretty well with my NASA acronyms today. Let's see if I can do this one. This is one of the bad ones. Osiris Rex.

• 2:41:02Speaker 02

  Origin, Spectral Interpretation, Resource Identification, Security Regolith Explorer. There we go. And it brought back a sample of an asteroid. And asteroids, as you know, are these rocks in space that were never built into larger planets. And so there's Osiris Rex. Thank you. And Osiris Rex is a small spacecraft, about the size of a car. And this is an illustration. It went to an asteroid called Benu. And Benu's about half a kilometer across. It is an asteroid that comes in and intersects the orbit of Earth. We don't have any idea that it will ever impact us. It may hit Venus before it hits us. But any rate, we sent a probe out there to bring back a real pristine sample of an asteroid.

• 2:41:46Joe Rogan?

  Which is just nuts.

• 2:41:48Speaker 02

  Oh, yeah.

• 2:41:49Joe Rogan?

  That they could land on an asteroid and then return back to Earth.

• 2:41:51Speaker 02

  Do you know about this mission?

• 2:41:53Joe Rogan?

  Yes.

• 2:41:54Speaker 02

  Okay. So the asteroid's going faster than a speeding bullet. It doesn't have enough gravity to go into orbit around, really, until you're really close. We had to catch the thing, get ourselves situated around it, get low enough to get into orbit, match its spin rate. And then when they got out there, I love this. NASA designed this little sort of vacuum cleaner to vacuum up a sample of the asteroid. The whole surface was covered with big boulders. They were just like, I mean, literally, like, fuck. It's like, it's not going to work. There's nowhere where there are small, fine, grain, you know, things we can just suck up easily. So they survey the whole thing. They find there are these tiny little craters that have some dust in them.

• 2:42:35Speaker 02

  And then they have to reprogram the spacecraft because it wasn't meant to be so autonomous. It's so far away that a command one way is going to take 15 minutes. You can't joystick it. It's got to take itself down manually amidst all these boulders. They had to make the spacecraft autonomous after they launched it. They got there. It wasn't going to work. They had to teach it how to recognize where it was, how to wave off if something was too dangerous. This shouldn't have happened. And so they finally vacuum up the sample, they get it back to Earth. You know, they drop it on a parachute into the Utah Test Range. They open up the sample, and all of the nucleobases of our DNA, not just little molecules, the

• 2:43:18Speaker 02

  letters of our DNA and our RNA are in that sample. We don't think that's a coincidence, right? You know, the reason our biology is based on those molecules is that they're available. They're falling from the sky. That asteroid was full of water. At one time, the minerals were soaked in water. They were wet. So the asteroids were delivering water and a little bomb of proto-life. Not life yet, but the genetic code, the letters of our genetic code were in that asteroid. And not just our genetic code, but there were nucleobases we don't even use. Maybe life on other planets would use different nucleobases, but we can already sample them from the asteroids.

• 2:44:02Speaker 02

  You know, the idea that our biology was brought here from these colder, more distant parts of the solar system, and it's literally raining down on us. You know, I expected to find organic molecules. I expected to find amino acids, you know, those sort of the things that make up our proteins. I was amazed we found all of our nucleobases, all the letters of our genetic code, both for DNA and RNA. They're already there in the asteroid.

• 2:44:29Joe Rogan?

  Which is nuts, the idea of panspermia, and that this is how life got here in the first place.

• 2:44:36Speaker 02

  Well, yeah, absolutely. The building blocks just come down from space, and they hit everywhere.

• 2:44:42Joe Rogan?

  From where?

• 2:44:43Speaker 02

  Well, that's a little bit less mysterious than you'd think. The universe is great at making large-scale organic molecules. Carbon is a sticky atom, and you make-- dying stars are great at making carbon. It's one of the most common things that comes out of a dying star. And the electron structure of carbon wants to grab on to other atoms. It's literally the quantum mechanics. And so you have this naturally-- I mean, this building block of carbon. And dying stars are pumping out this stuff into the galaxy. It gets collected by gravity into these clouds, and then the carbon starts glomming onto each other. And so space itself is very good at making our chemistry, carbon-based organic chemistry.

• 2:45:31Speaker 02

  So then, in the icier outer reaches of the solar system billions of years ago, you know, the planets are forming, but there are some smaller bits of ice and rock that never quite got built into the larger planets. They're still floating around out there. And, you know, and then they occasionally come in and hit us and deliver water, deliver organics. You know, the Earth was once, you know, a pretty much a dry, hot ball of lava after it formed. You know, a lot of the lighter stuff probably arrived from collisions coming in later. Wow. Yeah. And, I mean, the engineering, the audacity of reprogramming, this thing shouldn't have worked, and they saved it.

• 2:46:16Speaker 02

  And they made it work. This brilliant team of people. You know, I mean, it just, I mean, as somebody who was a minor manager at NASA, you know, and a minor scientist, I mean, just what a team can accomplish, I mean, not just a single person. You know, one of the big things that I really respected at NASA was, once you had your team of people, and like I said, nobody's perfect. Some people are higher functioning, some people don't contribute as much. But once you have your team identified, trying to make sure you get an input from everyone, and they're not going to give it to you the same way. There are the people that are really assertive in meetings, and they've got an idea immediately. They speak up and they give it to you. And then there are the quieter people that are going to take longer to process.

• 2:46:58Speaker 02

  They're going to need a little more time, they don't like to be put on the spot. You know, trying to make sure you get an input from everybody on your team, and sometimes the solutions come from the people that you might not have even asked. You know, that sort of respect for everyone on our team has something to contribute. You know, give me what you got, even if you don't think it's good enough, even if you think it's a stupid idea, even if you think it, you know, give me what you got. The power of that, I saw over and over at NASA. It's not just one type of mind, not just one person that's going to solve the problem.

• 2:47:33Joe Rogan?

  That's awesome. That is awesome. Thank you so much for being here. I really enjoyed this conversation. It was really great.

• 2:47:39Speaker 02

  I did too. It was a lot of fun.

• 2:47:40Joe Rogan?

  It was fantastic. And thank you for everything that you put online. It's so valuable, it's so educational, so interesting. It's awesome.

• 2:47:48Speaker 02

  I'll try to do a little more and have some fun with it because I guess I'm retired now and I have a chance to be a little more creative with it. So we'll see what I can do.

• 2:47:56Joe Rogan?

  You definitely should do something. A YouTube channel, something along those lines. Yeah, definitely a podcast, something. Do it.

• 2:48:03Speaker 02

  I will try.

• 2:48:03Joe Rogan?

  Please do. If people want to find you on social media, do you have that?

• 2:48:08Speaker 02

  Well, yeah. I mean, so I, somebody had taken Michelle Fowler, so I go by Dr. Michelle Fowler. There's a Facebook page and Instagram. And I do have a small YouTube channel set up. I'll do more of that. I just started doing TikTok. And so I'm just getting started, but I'll try to put some stuff out.

• 2:48:26Joe Rogan?

  All right. Awesome. Thank you so much.

• 2:48:28Speaker 02

  Thank you.

• 2:48:28Joe Rogan?

  All right. Bye, everybody.
