There's only one universe.
There might be eight planets in our solar system, tens of thousands of asteroids,
and there might be 100 billion stars in our galaxy,
and we think there are over two trillion galaxies in the observable universe.
Universe only have one.
Makes cosmology extremely hard.
Any sufficiently advanced technology is indistinguishable from magic.
Open the pod bay doors, out.
Okay, Dr. Keating, I was at this event in the Bay Area like a couple months ago.
And some people were talking about like some random physics guy that was on Joe Rogan.
You were on Joe Rogan like what in September or August of this year?
Yeah, I got on in August.
I ended up making the track to Austin in the middle of a hurricane here in San Diego,
but survived and had a good time with Joe and Jamie and the whole crew out there.
It's quite an operation, which I assume you'll be at someday.
you'll be exceeding.
Joe Rogan used to be the Christopher Sweat of five.
Yeah, that would be cool.
What was it like there anyway?
I mean, you see like the YouTube videos,
but I'm sure it's like different when you're like on the mic.
You know, I did a blog post on my blog at Brian Keating.com,
which all your viewers, listeners should go to because I give away these meteorites,
which I gave to Joe.
I gave Joe a meteorite.
I give them away to different folks throughout the month.
When, after I came back, I said, well, you know, how many people,
I was only the 2000-23rd episode.
That was pretty cool.
So a lot more people are interested.
And since then I got a lot of question, you know, can you connect me to Joe?
Can I go on?
I've got a book coming out.
The answer, unfortunately, is always no.
Just he does all his own booking.
He reaches out.
He'll get in touch with you if he wants to talk to you, basically.
So he got in touch with me, invited me on.
And, you know, partially that was, I think, because I'd been on Jordan Peterson, you know,
on his podcast.
and I'd been on Lex Friedman, and they're all very close.
And so, yeah, so I got invited so, but because people are so curious, I wrote a blog post,
you can find it, what's it like to be a guest on the Joe Rogan experience?
And I kind of go through it and take a reader or viewer on it throughout the whole experience.
Just like for any of my readers or listeners that are tuning in, Dr. Brian Keating hosts like a really epic,
we'll call it physics podcast.
But, I mean, it seems like a lot of your guests are sometimes in different parts of the heart sciences, mathematics and biology.
Philosophy, yep.
I've had a young, you know, modern day street philosopher named Christopher Sweat.
Yeah, thank you.
You can find that in the back catalog.
That was a great combo.
It is.
I think it was called philosophizing in public.
That's right.
Actually, I want to ask you like some physics questions, but, you know, my,
my base of knowledge isn't in physics.
You're the expert.
And so are many of your friends and colleagues.
But so, like, I was taking some history of science classes,
which was pretty much like philosophy from a number of physicists.
And we got into the topic of cosmology.
And I thought cosmology was super interesting because to me,
it's like another way to describe space.
And I have a very spatial orientation,
even when I'm thinking about networks or computer systems.
But like, so I notice you're pegged as a cosmologist.
What does that mean and how does that relate to physics?
The relationship is because the word cosmos, the prefix cosmos means beautiful or appearance.
And it really is indicative of the fact the universe is a beautiful place.
It presents itself to us.
And we can only glean from it what it wants to show to us, like much like the ladies in our lives, right?
They're kind of mysterious.
And to get it to reveal things is not.
It's not like any other science.
Even it's not like astronomy.
So cosmology is a branch of astrophysics.
Astrophysics are the laws of physics applied to astronomical settings.
So stars, galaxies, planets, even astrobiology, life in the universe can be subsumed within that.
And then cosmology is the study of the governing principles of the universe as a whole.
And so I always point out that, you know, when people say that astronomy is hard because we actually cannot do an experiment in astronomy.
We cannot take, you know, this meteorite, which I will provide to your listeners,
Brian Keating.com.
And I can't expose it to an extra billion years of the solar wind to see, you know,
if that impacts the isotope ratio or if that would impact an amino acid that's trapped
somehow inside of this beautiful, you know, shard of the early solar system or the pre-solar
system.
So I can't do any of that.
And so, but cosmology is even harder because there's literally billions of meteorites.
and, you know, I wouldn't give them away if there weren't so many of them.
And, you know, they cost a little bit to get, but that's fine.
But I wouldn't, you know, certainly they come to us, but they're one of the few things that even comes into the earth, besides photons, some particles called neutrinos.
And, you know, basically that's it. Solar wind and so forth.
They're very, very rare examples where you actually have something of either energy or matter or both to study in your laboratory.
everything else has to be reached to you by but think about it chris the universe is the only thing the
uni means one so there's only one universe there might be you know eight planets in our solar system
and you know tens of thousands of asteroids and there might be a hundred billion stars in our galaxy
and we think there are over two trillion galaxies in the observable universe at least you can do
statistics and see how many of them are red how many of them have spirals how many of them have
nebula how many of them could have life how many of the of the exosolar planets
have my colleagues discovered with the Kepler satellite that are in the Goldilocks zone where you can
have liquid water and you can have potential for habitable worlds to exist. And yet there's only,
you know, say, five or six thousand of those. But still, you can do observations on a multiplicity
of those. Universe only have one makes cosmology extremely hard. God, that's so fascinating.
Okay. And then also, I mean, there, you know, there's all these schools of thoughts that have emerged.
let's even just say like Newton to today.
But so like, why is it impossible to have a conversation about physics without God at some point?
Oh, that's, yeah.
Yeah.
That's another question.
I'll ask you this.
Like, what's your favorite day on the calendar?
Every year that comes up every year.
What's your favorite day?
My birthday.
Yeah, exactly.
I usually ask that to people, the only person who's ever given me an out of the ballpark answer was Ben Shapiro.
I had Ben Shapiro on my podcast.
couple times. I actually just saw him when I was in Florida about a week. He's a contrarian.
He is a contrarian. Yeah. He's built himself a real empire and I've got incredible respect for him.
He like I am Jewish and we practice Judaism. He's much more strict and observant than I am.
But he's like a celebrity. I'm walking around Miami with him and everybody's not, you know, take a selfie, do
that. Even if they don't like him, they want to meet him because he's not only the most famous Jew
on the planet, but he's the most famous conservative and, you know, like it or not. I mean, he has a
people that that disagree with him all the time. Anyway, I don't have to do it. But I asked Ben Shapiro when
he was on and he said, Yom Kippur. And I was like, all right, Ben, you know, let's, let me see if I can
work down into my theory. But my theory is that the reason your birthday is so important to you is because
it's a singular event before which you have no, you could not have had personal knowledge of the
conditions of the universe that marked your entry into the universe as a coherent being, right?
Forget about reincarnation. I'm not going to tell us up. But so too, does mankind
as a collective, as an ensemble of literally 100 billion souls, just like you and me, infinitely
valuable, in my opinion, although some more valuable than others, some of the A-Hulls that have
lived throughout society. But anyway, ignoring that. So we look at that and we say the 100 billion
people have lived, each one of them had an origin point at some point, and they're curious about
what came before, and humanity as a whole is curious about what or if there was a universe before
our universe came to be. And in fact, Chris, if you, if you wrote the year on a ping pong ball,
you wrote, you had 2,24 ping pong balls and you put them in a bat, just since Jesus Christ, right?
Okay, just since the birth of Jesus Christ. And you put them in a bag. And you pulled out that bag.
And on the back of it is written, what was the prevailing view of the universe and cosmology of the year on which the front is written?
2023, we believe in the Big Bang. 22, believe that the Big Bang is the most plausible. You go back,
go back before 1929.
Okay, so less than 100 years ago, 96 years, 95 years ago.
Every single one of those balls would have had eternal, static, steady state.
Always been there, no such thing.
Oh, interesting.
And so the Bible, the Old Testament, the Torah came along and said, no, it is not, the universe
is not within, you know, did not create itself.
It had an origin.
That means something created it.
That means something is above the universe.
And we can argue philosophy, you know, theology. I'm not here to convert anybody. It's forbidden in my religion. But the point being, when you have an origin of time, it's as different as possible from the non-origin stories that existed before 1929, the Big Bang, LaMaitre, and Hubble. And eventually Einstein came around to see the light. So it's always been inevitably tied to that. In fact, as recently as the 1970s, the world famous Nobel laureate, who just passed away two years ago,
Stephen Weinberg. He said that I prefer, he preferred the steady state universe because at least
resembled that account found in Genesis 1-1, where there was a creation and had been there
forever. So scientists, 93% of all scientists members of the National Academy of Sciences, which is the
most prestigious academy or organization on earth, in my opinion and many opinions about science.
93% do not actively believe in God. They're either atheist, most of them, or agnostic.
A fraction of them are agnostic. It only,
to 10% are believers, whatever that means. Now, so there's always going to be that tension,
but especially in cosmology. I have colleagues that study quantum computers. Okay, those are
interesting, fascinating objects, but they never start thinking, well, like, how did the universe
begin? And what does that have to do with God or Jesus or like, or superconductors? You know,
people study superconducting magnetic or, you know, quantum dots like these things or whatever.
They don't actually have a necessary opinion about God.
It's not even remotely relevant, but when the very book that underpins, you know,
two-thirds of the world's, you know, practicing religions, namely the Old Testament, the Torah,
the Bible, that book starts, it doesn't start with like, well, that's a really delicious
animal that you can't eat, you know, called a pig.
And that, you know, it's not a book of rules.
It is a book of rules, but it doesn't start with the very first rules.
It starts with the origin of the universe.
And that in turn gives sort of a glimpse into the magnitude of what is the scope of cosmology
and how it then butt is up against or butts up against.
It's peak pollination season and my business is scaling fast.
To keep the nectar flowing, I need a phone plan with top priority data speeds.
That's why I chose GoogleFi wireless.
My connections stay strong even when the hive is buzzed.
Plus, unlimited plants started $35 a month.
Now that's a deal that doesn't think.
State. Explore GoogleFi wireless plans today. Plus taxes and government fees. GoogleFi wireless is not
subject to data traffic deprioritization during times of high network usage. Theology. What are some of the, like,
more pressing theories that you hear colleagues grappling with? And like, what are some of your thoughts on those?
You know, it's funny that, you know, one of the reasons I think I was invited on Joe Rogan is that over the summer,
he kind of, you know, poured gasoline, poured gasoline on his fire of whether or not the Big Bang
actually happened.
Okay.
And he did so in combination, so to speak, with this researcher, I won't even call him,
I mean, he's not a, he is a scientist, I guess, by training, he has a bachelor's degree,
but he's not a professional, you know, kind of academician, at least.
He doesn't have a PhD.
He's not conducting research in cosmology.
He works on something called fusion, plasma fusion.
but this guy Eric Lerner who'd written a book 32 years ago called The Big Bang Never Happened.
And that came out very soon after the first so-called Hubble Deepfield image came out,
which is a spectacular image.
It shows basically every speck of light you see with a handful, literally three exceptions,
are all galaxies, not stars, they're galaxies, there's three stars in the whole image.
That image takes up about the same amount of sky as this meteorite held at 10 meters distance.
It's a tiny speck of the sky.
6,000 galaxies are in there.
And the galaxies, you know, I call it a cosmic wallpaper because it's just incredible.
It's this beautiful image of just the most important images of all time.
And back then, he wrote that, oh, there are galaxies there that shouldn't be there if the Big Bang were true.
And by the way, I have this great new idea called the steady state or tired light universe where the universe is infinitely old, is not changing, is not expanding at all.
and you cosmologists are just totally wrong.
And then over the decades, he's just been proven, like,
it's just taking the L after L after L.
And there's a couple of things.
Obviously, every theory is always provisional.
Even the idea that the Earth is a sphere or the sun is a sphere,
it doesn't matter.
It's not.
The Earth is not flat, but it's much closer to a sphere,
but it's not a sphere either.
It has different multipole moments it's called.
So you can't say that a theory is ever going to be proven
in the same way a mathematician or a logician
could say that a proposition,
is true axi-matically within its own set of mathematical framework. There's no equivalent to
girdle's incompleteness theorem, Chris, in the physical sciences. That means there's no way for me to tell
if something is truly scientific or not. That means you can't prove something in science. I can't prove
that the universe had a big bang. I can only present evidence for it. And that's like, I can't prove,
you know, the theory of evolution is true. We just have substantial overwhelming evidence for it.
It doesn't mean someday some aspect of it couldn't be wrong or that there aren't problem. I mean,
And there's huge problems with evolution, as you probably have heard about.
It doesn't mean evolution as a whole is wrong.
It just means that there's challenges.
And thank God, because that's how my, you know, that's how my mortgage gets paid, right?
That there's problems that there's things we're looking for.
Otherwise, you know, everything would be known and we'd just be collecting stamps.
So every, yeah, every 10.
So now recently in 2021, the Hubble, the James Webb Space Telescope was launched, successor to Hubble.
Christmas Day, 2021, it returned spectacular images, including an exact copy of the image that
Hubble made, except it can go much deeper in space and time because it has infrared capabilities
and wavelengths get stretched by the expansion of space and time, revealing more and more things
that wouldn't be revealed unless you have the sensitivity to call infrared radiation.
Now, Dr. Kitting, you brought up space time, and this came up in a conversation I was having
with more like computational computer scientists, folks and engineers.
And one of them was saying that like the way space time is presented is to,
esoteric for his taste. And I wasn't actually sure if that's true because I actually think you can
like use charts to like kind of look at the behavior of, you know, certain variables in
space time. But how would you describe space time and like what is that for the non-physics person?
Yeah, it's a simple question, right? That's almost impossible to define in a way that that's
appreciated by even by scientists or agreed to by scientists.
And space time is the sort of network of all possible points that could exist in a mathematical
model.
So it's a mathematical representation of the environment that we find ourselves in.
So pure mathematicians could talk about space and they could even talk about time as an
additional fourth dimension added to the three dimensions of left, right, up, down, backwards
and forwards that we can enjoy.
And actually they can envision a 20-dimensional spaces.
We can't envision it, but they can mathematically model it.
So some models are more, are more relevant and pertinent than others.
So you could also model the structure of our, just on Earth, you could model it as a three-dimensional spherical geometry.
And I actually would have the same exact properties as a three-dimensional Cartesian geometry.
So that's all possible.
But what was found is that to explain the peculiar idea and the finding and the observation, evidence, in other words, that the speed of light was constant for all observers, meant that you had to give way to the notion of an absolute time.
So time was thought to be absolute in Newton's conception of space and time.
Events played out in time. Time ran linearly and objects moved with velocities and accelerations according to Newton's equations.
and according to the laws of universal gravitation and whatnot.
When electromagnetism was discovered, the laws of electromagnetism were made quantitative by Maxwell in the 1850s,
they were found to have a speed of light, a speed propagation of these waves that was assigned the speed of light,
but it wasn't believed that that speed of light was constant.
It could move if the observer was moving.
And then later thoughts by Einstein, Poincorrae, Minkowski, and others started to conjecture that actually
you couldn't define an absolute relative absolute coordinate system that would cover all observers
in any type of motion with a fixed time coordinate. In other words, you could have events
that seem to be exactly perfectly simultaneous to one observer that were completely non-simultaneous
to another observer, meaning that a cause could be, could precede an effect, or rather
an effect could precede a cause rather. And so that's very bizarre because you'd like to think
you light off a firecracker match and then all of a sudden explodes,
but you could actually see from another observer's perspective,
no, the firecracker blew up and then it was lit.
So these things didn't make sense unless you made a postulate of the constancy of the speed of light
as a maximum velocity for material objects.
And so when you do that, time now becomes malleable.
Time becomes a variable, and that makes, together with space, space time.
Jeez. Okay.
We'll have to bring some good illustrations up on that one and see if we can simply.
But it is fascinating because I think there's like a lot of engineering prowess that is going into the world of space time and especially in computer systems.
So like I'm sure people are asking you about artificial intelligence and, you know, your kind of perspective there.
So I actually have like a twofold question.
Okay, so one, do aliens exist?
And two, is that what artificial intelligence is?
I've become an AI sort of optimist rather than, you know, a lot of people like Elon Musk or
others that seem to be fearful of what it could unleash.
For one thing, I found it to be just like rejuvenating for my scientific career.
I mean, it's like now I feel like Madonna, you know, like it's basically allowed me as an
experimental physicist.
You may not know the distinction between an experimental physicist and theoretical physicist,
but an experimental physicist will actually build a telescope.
and build a detector system and use it and map it out and characterize and quantify all of its
flaws, all the problems with it, you know, the cracks in the lenses, the distortions, the pointing
errors that it makes. Experimentalists will make the most sensitive possible measurement.
And then use those to not prove a theory right, but to prove other theories wrong. As I said before,
our job is not to prove stuff. It's to falsify other stuff effectively. And so my job is to collect
evidence and to build the technology with my colleagues that are doing it. So,
but with artificial intelligence, I'm able to, like, actually get into the realm of theories
and start making predictions or doing big data analysis, machine learning. Stuff, I, you know,
I was always an okay coder, but it wasn't one of my foretays. And now one of the three branches
of astronomy is basically built, are one of the three tools that are useful in astronomy. One is
telescopes. The others are your brains, like theoretical ideas. And then the third are,
computer simulations. Those are three major classes of tools that we use. And now I can like start
to move into some of the other two domains that I haven't been expert in. And that's only going to
get better. It's, it's really been great. It's been good for teaching. And what I've thought about
with AI is, yeah, so can AI effectively, I think what you're asking is, you know, could AI
effectively be super intelligent, could do everything a human can do? And then why stop there? You know,
people always say, well, like, we're going to achieve AGI, you know, but like there's no barrier
like you like a black hole. And they call it the singularity. But, but, but that's kind of,
you know, just a shorthand for like things are going to get really whacked out pretty soon in
29, according to one of my upcoming guest, Ray Kurzweil. But the idea that that AI would stop and
then you've reached human intelligence. There's nothing beyond it is not a done deal. So some of
the ideas are that, no, it keeps getting more and more intelligent. In fact, it becomes almost
godlike. And then the question is, well, why would a godlike entity create, you know, people,
like what are we here for? And so that leads other people like David Chalmers who have had on the
podcast or Nick Bostrom who have had on the podcast to then speculate in something called
simulation hypothesis that were actually simulated beings. And then that interfaces nicely with
some ideas that Donald Hoffman and others have had that, you know, consciousness is really just an
interface to deal with evolutionary realities that we would otherwise be inept and incapable of dealing
with. So when you think about these superintelligence is they are kind of like gods or you could also
think of aliens as like gods. If we don't understand how life on earth originated, we do understand
evolution very well, but there are problems with, you know, some of the macro evolutionary processes
that we haven't quite figured out, missing links, all these other things that you've heard about.
But, you know, those might be solved in, you know, tomorrow for all we know. But the question of
how did life itself get started? That's a huge.
consideration in physics and biology and chemistry and so forth. So some people have thought,
well, if there were aliens, they are godlike, they're 20 centuries ahead of us. They won't look like
us. And they certainly won't travel from point to point to, you know, bring their, you know,
XNA or whatever they have instead of DNA with them. They'll just send their AI avatars to travel
at the speed of light, which is the ultimate speed limit, as I said 10 minutes ago, thanks to Maxwell
and Einstein and Mankowski and others. So in that sense,
How do you break that barrier?
You can't.
So you send your digital avatar to do the exploring for you.
And the virtue is they're even more expendable than drones or robots that are flying in Mars right now,
as we have a helicopter on Mars, right?
But why do that?
Why send any atoms whatsoever?
Just send the bits.
So when you take this complex melange and you take enough ketamine and MDMA, then you might start to, like,
photossociate these things together in this melange in your mind and then start to say,
well, anything is possible.
And then some people have speculated, yeah, there's a guy troll on Twitter that just
constantly tries to, you know, berate me to have him on my podcast.
Okay.
And, you know, I know he's out there listening to everything I do.
That's nice to have a stalker.
I do like him for everything negative I say about him.
But, you know, his whole idea is AI or aliens and aliens are actually craft and we have bodies,
but they're AI body.
So anyway, you put enough buzzwords together.
you can get anything.
But it's important to, you know, to really realize this guy, Carl Sagan, said, you know,
extraordinary claims require extraordinary evidence.
And right now the question of whether or not there's life outside of the Earth surface,
or I'll say outside of the solar system.
I just spoke with Craig Venter, who mapped the human genome 25 years ago for the first time.
And he's like, no, there's definitely life in space.
There's life on Mars right now.
There's like there's life on the outside of the ISS.
I'm like, what the hell are you talking? He's like, no, all those, I'll say poop, the alien
astronauts make has coded this whole like, you know, the exosphere. And so, yeah, the outside
of the space station is crawling with microbiome and it's not going to die. And some of it's gotten
to Mars by now, by virtue of just the exchange between planets. So long winded way of saying
AI is super awesome. I hope that they'll remember this conversation if and when they hear it.
But the point is we have to be careful about ascribing too much
power to it, but also not taking it seriously enough.
You said this place was steps from the water.
We just haven't found the steps yet.
How much did we save?
Enough.
Enough to get lost.
Or you could book a stay with Hilton.
Welcome to your oceanfront room.
Just steps from the water.
The Hilton sale is on now.
Book on Hilton.com or the Hilton app and save up to 20% to get the stay you expected.
When you want savings, not surprises.
It matters where you stay.
Hilton, for the stay.
Okay, that's understandable.
So I know Eric comes on your podcast occasionally,
and I don't remember if it was recent,
but he had made a call for, like,
a number of physicists to come together
and kind of put old ideas
or maybe kind of old baggage in the discipline behind them
so that new innovations could take place
or, like, new research could take place.
Like, how do you see, like, the discipline
and being constrained today?
And why is that?
Important to realize Eric's not a physicist.
He does, you know, kind of produce ideas for mathematical, physical models.
And the most famous one, he calls geometric unity.
We've talked about that a lot of my show.
But he's not an experimentalist, you know, any more than I'm, you know, an archaeologist.
So it's important to, you know, kind of always try to, you know, constrain enthusiasm.
about what these theories can do.
But his main kind of claim, you know, to this, to this field is that string theory has been
extremely damaging to our understanding of reality.
It's been stuck in this kind of underproduction mode where it hasn't shipped the product
according to him.
And, you know, it's been around for 55 years now in one form or another since it was first
proposed in late 1960s.
And since then, you know, it hasn't led to any testable predictions as far as we can
tell.
And I've had on, you know, Brian Green recently.
I've talked to Kamran Bafa.
I've talked to Lenny Suskin.
I've talked to all the leading luminaries, Juan Maldesana.
I haven't talked to Edward Witten.
He won't come on my show for some reason.
But, I mean, it's not because he's going on other people.
He's done rogue, and he just doesn't do podcasts.
And I respect that.
That's fine.
I don't respect a lot of what he thinks about Israel and other things.
And we can talk about that some other time.
His political stances lead me to think, you know, to diminish his respect.
His political stance?
Edward Witten, Ed Witten, the Institute for Venn's Study.
He's one of the godfather of modern string theory.
But according to Eric and others, many others, Sabine Fosin, Lawrence Krauss, these physicists, they're all theoretical.
Like, honest to goodness, theoretical physicists, that that's their training.
And they say the following, you know, that string theory has been a failure.
It's been leading scientists astray.
I mean, Sabina wrote a whole book about that.
Lee Smollin wrote a whole book, Lawrence, you know, many, many books.
Peter White, Columbia, who's a researcher there, not a professor.
So, yeah, so all these people have really thought about this idea is of basically a failure.
And worse yet, it's sucked up the oxygen resources and talent over the past 40, 50, 60 years
almost.
So I see a point to that, you know, when you have a theory of like we were still talking
about phlogiston and phrenology.
And it was like taking the best minds of medicine.
and they were all dedicated to like phlogist or phrenology or, you know,
or lobotomies and stuff we know don't work or haven't really produced anything
that is in contact with the experimental program of scientists like me, whether,
and it's not because of lack of trying.
It's not like they said, oh, we know about the LHC, so we're just,
but we're going to just make a prediction that can't be tested by.
No, no, they hope to God, they prayed that they would see stuff at the LHC,
and many people predicted they would see stuff at the LHC, and they never did.
And this is very reminiscent of people like my friend Lee Cronin, who's been on my show many times.
Sure.
Talks about, oh, we're going to make life in a jar, you know, basically on Earth and a laboratory.
He's going to do it in the next 10 years.
And it's always 10 years from now.
Okay.
It keeps getting updated.
So the question of is a sociological one rather than a scientific one.
So what Eric's saying is it's time to invest in other ideas.
And the problem that he sees, which I agree, is that you'll have people like him or Stephen Wolffron or, you know, Sabine or, you know, are other people.
people, Peter White, and they'll have ideas, Garrett Leasey, and they'll have ideas for alternatives
to string theory, loop quantum gravity, E8, you know, Eric's geometric unity, Stephen Wilfrum's,
physics project, you know, kind of computational physics. And none of them will ever study
the other ones. So you have all these people and they're each like kind of accusing the other
ones of being either, you know, cranks or crackpots or in left field, but their theory is correct.
But why won't anybody listen to me? And I'm like, you know, this doesn't happen in experiments.
It's not like I can do an experiment and people won't pay attention to it if it has a result.
There are people that disagree with that. And I've had, I wrote my first book about that,
you know, how we were actually wrong and we made a claim that wasn't substantiated by the data,
you know, that would later come in. It was at the time, but we made it a misinterpretation.
That happens all the time. And you should have that kind of healthy ecosystem.
system. But in theory, it seems to me to either be string theory on one hand, which has tons of
investment of time, money, resources, people. And that's 90% of the field. And then 10% are
alternatives to string theory that get almost no attention, including from the cohort of people
that are researching it with the one notable and very, very, you know, laudable exception of Eric Weinstein.
So what I'm saying is Eric is the only one of all these people that I've met who have taken the time,
had the courage and had the collegiality to study all the alternatives that have been presented
to string theory as well as string theory and ask really tough questions of people like Brian
Green, Stephen Wolfram and others. And so no one else is doing that besides Eric. So I give him
a tremendous amount of credit. Well, and I know that I know it's not easy to summarize,
but like what are some of the basic axioms of truth in string theory or like what's the basic
context of what string theory is at its foundation? Yeah. So string theory,
follows the atomistic kind of tradition that, you know, matter is made of atoms.
Atoms are made of, you know, protons and electrons. And then protons and neutrons are made
of things subdivided into quarks. And then there are other types of matter that aren't subdividable
into quarks, neutrinos and electrons and so forth. And strength theory is the notion that there is
a subdivision, but the subdivision occurs on a scale that's far, far smaller than the ratio of, say,
the size of the proton to the size of the electron or the size of the proton to the size of an atom.
It's by many tens of orders of magnitude smaller, such that the microscopes that you would need to
see it are basically the entire universe in size, or many, many times the size of the LHC for sure.
So in that sense, what do you do when it makes a prediction that can't be proven wrong?
So there are very few predictions in string theory that are experimentally testable.
And so, you know, for that perspective, there is a great challenge.
It's different than most forms of science.
You know, science should have something predictable.
You know, even the Big Bang, you know, the Big Bang was sort of conjectured in its current form in 1929, as I said, and then made more modern and had more evidence.
And then finally the cosmic microwave background, which I study came along in 1965.
And we're still mining it now with, you know, literally 60 years later almost with new telescopes and technologies.
So this, the field took, you know, but by some means, people are questioning the Big Bang model, like I mentioned before.
Those are extremely far reaching borderline, you know, crackpot, if not crackpot adjacent, you know, outliers.
It doesn't mean that I'm not condemning them. I'm not censoring them. I'm just saying their ideas are in conflict with the observations that we have.
Their complaints against the Big Bang are easily countered, you know, all with a possible, you know,
literally one or two exceptions that we can't answer right now.
But the Big Bang model has been around for a long time, longer than string theory.
So some people say, well, give it time.
But the problem is, you know, back in 1929, you could have said, well, we could measure a three-degree
Kelvin background in 30 years from now.
And they would have been able to predict it.
And actually, some people saw evidence for a three-degree background in cyanogen molecules
and nebulae in our galaxy.
And so in the 1940s.
So it wasn't beyond the realm of possibility to say, well, give me 10 years.
But the question is, how long do you keep, you know, waiting for this product to ship to use Eric's language before you give up on it?
And it wasn't like the Big Bang was the dominant narrative at all.
In fact, for the first, you know, 40, 50 years, people were really obsessed with the steady state model and worked very hard on it.
And then until it was impossible to adhere to anymore.
So this notion of paradigm shifts that you, the structure of science,
revolutions and stuff. That's not really been born out, at least in, you know, in most fields of
physics. It's really, it's taken decades. It's not like overnight success is manifest. So string
theory could be in that situation or could be utterly wrong, never provable, and therefore it is a
colossal waste of time if you look back. Well, I also see that like certain scientists may have
produced thought during the time that was just way too far outside of the orthodoxy. And maybe
didn't circulate at a higher level until tens or even hundreds of years after they had already
passed away. So, I mean, it's also like, you know, not every solution is going to be immediate.
But so did string theory come into play in the 40s or 50s? Is that one that you made?
No, no, no. No, it started in the late 1960s.
Late 1960s. People like Nicaoku and others have been on to talk about it. Yeah, it was a late
1960s, but it really picked up steam in the in the in the 80s. There were some big problems with it.
It really wasn't. It didn't. It had some what are called anomalies. It had originally, you know,
like two dozen dimensions instead of, you know, the four dimensions that we see now, as I talked
about earlier. But, but now it's not like it has four dimensions. And now the minimum viable
product in, you know, kind of Silicon Valley speak has 10 dimensions. And that was really discovered by
unification by Ed Witten and others in 1984, which is 40 years ago, that was the last
major development in string theory was the reduction in dimensionality from 26 to 11 and then
eventually 10 dimensions. And now we see very little, you know, kind of progress. There's something
called ADS CFT, which is Juan Maldesina. I've talked to you about that. But, you know,
those are kind of tangential. Those are aspects of string theories that aren't necessarily string
theoretic relevance in terms of predicting the masses of particles, the interactions of, of forces
and fields, and even candidates for dark matter in so-called supersymmetric models. So these,
these don't exist. And there's no evidence for it. And worse yet, there's no, there's no larger,
larger Hadron Collider on the horizon for these folks. So, you know, if I was a string theorist,
I probably would be looking at alternative models. It doesn't mean, by the way, that these models by
Eric or Stephen Wolfram or Garrett Leasey or Leesley or Lees-Mullin are right. In fact, they have
huge problems themselves. Okay. This is so fascinating. I decided to study political science,
so pretty much everything in the discipline that I study is contentious or at some point
leads a physical conflict. Yeah, it's very extreme. Yeah, and I get to look at the polarizing
stuff up front and interrogate it. There's maybe like less contentious stuff, but whatever,
it's politics. How is politics like in society affecting like your classroom, the things that you're
doing on the university campus and just kind of your work, are you dealing with any of this
like blowback that we're hearing about in the media? The last three months of my life have been
ultimately consumed almost 100% by campus politics of a kind that I didn't think was possible
and it was all nucleated and initiated by terrorists in Hamas and Gaza that massacre,
1,200 Israelis, you know, some as young as, you know, six months old and kidnapped babies as
young as six months old, Holocaust survivors in their 80s, women raped them, you know, horrific,
you know, just brutal, disgusting, animalistic attacks. And the day after this attack occurred,
which occurred on one of the holiest days of the year in Judaism, it was a Shabbat, a Sabbath.
it was during the celebration that marks the final holiday of the high holidays,
a month of high holidays.
So imagine like Christmas,
everyone's in their churches and praying and a bunch of,
you know,
terrorists come in and slaughter,
you know,
the equivalent of 30,000 Americans and kidnapped the equivalent of a thousand or more
2,000 Americans.
So this is just,
you know,
unprecedented horrific slaughter of Jews on a mass scale,
not witness since the Holocaust.
And what was the reaction on campuses,
including mine?
vigils for, you know, the people of Palestine, of Gaza, celebrations of the martyrs,
i.e. the Hamas scum terrorist, Nazi individuals, and celebration of them and a glorification of them.
And then it was followed up very rapidly thereafter by weak, meat, mouth, defense of free speech
on campuses when we had had, you know, horrific kind of, you know, totalitarian cram down our thought,
thought police of what we can say, you know, I had, I was, uh, criticized once for a tweet that
I liked. It wasn't even something that I posted had to do with, uh, with being anti pedophilia,
uh, which I thought would not be controversial to like. But I anyway, you can like something and not
not support the individual that put it out, just condemning pedophilia. I was, uh, accused by my dean of
being insensitive to this or that. And this was, you know, back earlier January, February. And, and now
you see, you know, like literally calls for the.
the genocide and elimination eradication of Israel as a Jewish state and a replacement of a population
that has lesser connection to it. Still has a connection to it. But denying the undeniable
connection of Jews to Israel is a slander and a libel of the highest magnitude. Again, demonizing,
dehumanizing, calling six-month-olds colonizers and worthy of genocide. So it's been pretty
horrific, Chris, to tell you the truth. And I think a lot of it is, you know,
know, it's coming out recently with these college presidents going on camera, making absolute
clowns of themselves, but still seeing, you know, just in a rabid outbreak of anti-Semitism on
Twitter or X or whatever, and just seeing it in my replies and people accusing me of supporting
genocide because I'm a Zionist and I support the existence of Israel. So it's been a really
traumatic time for many Jews and non-Jews. I've had, you know, four of my Muslim, you know, my best
friends happen to be Muslims. There are two, uh, two, uh,
Three of them are Iranian, Persian.
And they hate, you know, they hate Hamas and Hezbollahs more than Jews do,
because they actually fled those kind of totalitarian regimes.
And these are professors.
These are some of the highest caliber research in the world reaching out to me.
Brian, you know, I just want you to know, I'm there for you.
So at the same time, it's been horrific, but it's been terrific to see the banding together of people of conscience from Muslims, Jews, Christians, atheists.
And to see that, you know, you know, we have to get past this and maybe, maybe the world will wake up to the, to the kind of oppression that it could be facing if we don't take action now.
So, yeah, I'm sorry to leave on a down note, but yeah, I've, you know, I always thought as an astronomer, Chris, you know, you probably think that, you know, we're on telescopes all the time.
But I'm actually on telecons all the time.
So I've got to Zoom meeting on two minutes late to, but it's been a blast.
And I can't wait.
So if you're listening to this on my channel, because Chris graciously provided the link,
we want you to subscribe.
So Chris, tell me where people can find you that are listening to this on the end of the
Impossible podcast channel, Brian Keating.
Just Google Christopher Swett, and you'll find a rant, my Twitter, substack.
It's all there.
And it's great to house you, Brian.
Great to talk to you.
I love that Chris's substack.
It's one of the few that I religiously read.
And it's great to have you back on my pocket, but really to be a guest with you.
Chris has been phenomenal.
and I hope we can do it again.
And just a reminder, your audience is the second most brilliant in the known universe.
I have the same mind as much.
But go to Brian Keating.com and you may win one of these chunks of four billion-year-old space schmuts.
Chris, thank you so much.
Amazing.
Happy holidays.
Happy 2024.
I hope to see you again, maybe in person.
Yeah, I agree.
Thank you, Brian.
