Starting point is 00:00:21 only at Yamava Resort and Casino, celebrating its 40th anniversary. You in? Must be 21 to enter. Ambition comes in all shapes and size. At First Citizens Bank, we roll with your goals because we're built for what you're building. Fit for your ambition for Citizens Bank. Hey guys, Matt here. Yeah, so I interviewed Dr. Brian Keating, actually Professor Brian Keating, although it says doctor here.
Starting point is 00:00:58 So I suppose he's a doctor and a professor. But setting that aside, the guys are just a fantastic human being. He's an amazing science communicator. I mean, just look at he's got some serious junk in his trunk here. he's interviewed 22 Nobel Prize winning guests. He of course has his own sort of slightly frustrating Nobel Prize story, which we go into in some detail in this. He came very, very close to obtaining the title himself.
Starting point is 00:01:23 But, you know, we discussed the possibility of the negative impacts of some of these sorts of processes on real science. But setting that aside, we discussed sort of early universe formation, sort of opinions on the Big Bang and stuff like that. We had a good laugh about English. food and different names of breakfast. He's just fantastic
Starting point is 00:01:47 because he's approachable, he's fun. You know, just look what we got here, right? So he actually says in the description of his website that if you have a look here, right, so this is the podcast, into The Impossible. I've been watching this stuff for years. Many of us in Chelten, UK philosophers have been following his work. It's just fantastic.
Starting point is 00:02:06 And because he's so smart and he's kind of on the inside of physics and science, just ask brilliant questions and gets brilliant guests as well, right? He's interviewed most of my guests. So Donald Hoffman, you know, Mike Levin, Philip Goff, amongst others. Although I did suggest Jenny Nielsen and I think that he was quite keen on talking to her with her topological unified field theory. Should be of interest to Brian and some of his followers.
Starting point is 00:02:33 But yeah, it says here, look, every week I provide you with long-term interviews, long-form interviews, rather, with a brilliant thought leader and deep dive into a fascinating STEM subject. I mean, every week he does this stuff, right? He works really hard on this. These are really, really good quality, well-produced interviews. You know, here's an example. Look at that. Look at this.
Starting point is 00:02:55 It's been hit before. And I'll get hit again. 66 million years ago, a rock from space, erase the dinosaurs. Yeah. This is the quality that we're talking. This guy is a professional science communicator, educator. look he gets all these fantastic guests on you know this is something to aspire to for me
Starting point is 00:03:15 I wish I had the know-how and the expertise to be able to deliver this kind of quality but yeah here he is Brian Keating I'm so honoured that he would speak to me for an hour he said he was on to another call straight after that which is unsurprising giving his charm wit intelligence and goodness of character we even touch on religion and God and all that stuff as well
Starting point is 00:03:39 which seems to be quite a common thing these days with my guests. So, you know, we always said we wanted to be there at the intersection of philosophy, science, mysticism, and, you know, the nature of the guests and the breadth of their interest and sort of almost sort of cosmopolitan intellects in a way. You know, it seems to be supporting that journey or a directive. So, yeah, it's a fun interview, and I hope you enjoy it. Speak soon. Take care. Bye.
Starting point is 00:04:12 Hey, Brian. Pleasure to see you, Matt. Thanks for staying up late and getting me up early here in California. Yeah, I imagine it's sunny where you are over in California at the moment. But yeah, thanks so much. It's a massive privilege to have you here. Because not only are you a sort of forerning physicist, leading thinker in science, but you're also a podcast. You're a popularizer of physics and science more broadly in philosophy. I mean, you've interviewed half, at least half of my former guests. So, you know, first of all, thank you from everyone within the Chelham and UK Philosopher's community, that you're doing a great service. And that actually sort of, I mean, could we start just by getting a bit of a kind of origin story,
Starting point is 00:04:56 you know, because, you know, perhaps not all of our members as familiar with you, but, I mean, for me, you're rock and roll. You know, I get beers and pizza and watch you guys on Friday night. It's just fantastic stuff, right? But could you tell us about how you ended up, you know, doing this and why it's so important to you? you know, why physics? And, yeah, tell us about your journey, Brian. Yeah.
Starting point is 00:05:14 Well, obviously I did it for the money, you know, is something I always wanted to be wealthy and famous and earn the respect of podcasters everywhere. No, I mean, it's funny because, you know, podcast didn't exist, you know, 25 years ago. And you see behind me if you're watching it, I don't know. This would be on video, right? So you'll see the open the pod bay doors.
Starting point is 00:05:33 So that's my catchphrase, but that is actually the origin of the word podcast. It comes from 2001 a Space Odyssey, or Arthur C. Clark, his famous pod, you know, pod in the pod bay doors, that led an engineer an apple named Vinnie Serico to come up with the idea for the iPod. And then literally the rest is history once that became, you know, kind of a noun. So the, you know, journey that we're on now, both of us didn't even exist, you know, literally 20 years ago until 20 years ago, I think, this year. So there's no way I could have, I could have expected it, predicted it.
Starting point is 00:06:09 coming up on a third of a million subscribers just on YouTube, another 100,000 on audio. And it really came as a result of the pandemic. It really the only good thing that came out of the pandemic, besides more time with my kids and wife, was the, you know, kind of ability to, you know, middling people like me to get top guests like, you know, 22 Nobel Prize winners and multiple authors, Pulitzer Prize winners, Fields Medalists, you know, they were, you know, confined to their homes as everyone was on this little, you know, 1080P screen that we're on. So it's sort of a miracle that led to the fact that all these book tours got canceled. And as an author, I knew how important book tours were.
Starting point is 00:06:55 And I said, well, let me do a thing where I can do a virtual book tour from these big names. And I ended up getting, you know, kind of the Matthew effect, Rich Get Richer, and the more good guests I had on and great guests I had on. that would lead to more and more. I can't think of anyone, you know, that I really, you know, haven't had on that I'm just dying to come on and he or she won't come on. So it's been, it's been wonderful. And but, you know, my actual origin story started, you know, over 50 years ago in New York State on our island. You know, it competes with the British Isles. It's called Long Island.
Starting point is 00:07:30 I was born there. My father is a professor of mathematics at SUNY-Stony Brook. And that was my personal big bang occurred there. I guess, you know, maybe it occurred nine months earlier, if you count my parents. But we came to PG-13, of course. And the journey to become a scientist, you know, it was like being, you know, a wizard or something or an ice cream taster. I never thought, oh, this is something I can actually do for a living to be an astronomer, a professor at a top university in the world and travel the world and go to, you know, six of the seven. including Antarctica. I still have to go to Africa. That's on my bucket list, of course,
Starting point is 00:08:12 but I've given speeches on six continents. And, you know, never would have thought it would be possible, but for the fact that, you know, kind of by luck and hard work, I think I work really hard and always have to really, you know, be in the mix of the most interesting aspects of physics, astronomy, and cosmology. And now science popularization is a great honor that I get to do. And, you know, normally on a Tuesday morning, like we're talking, you know, I might be on one of four different telecoms, you know, talking about, you know, some strike in Chile or, you know, some shipment to Antarctica or whatever that went awry. And, you know, those are all conversations I would say I have to have. But conversations like this and with my guests are conversations I want to have, you know, to share the intellectual, you know, kind of energy that I get is a process that really is. is truly exciting. And there's no better time, I think, at history to be a cosmologist or an astrophysicist
Starting point is 00:09:12 like I am. And then all the more so to get to talk to great minds all over the world, you know, at the speed of light. So it doesn't get any better than this. I'm so blessed to be able to do it. It doesn't. And, you know, that's the rock and roll sort of element for me as well. And COVID affected me as well. Time with the kids. Time to do what you wanted to, you know, sort of like go for walks and stuff. I get some fresh air, get some exercise and watch guys like yourselves on your podcast sharing some of the most complex, deep, profound ideas you could possibly imagine. That's just, it's blissful, isn't it? And it's so cool. And for all of my guests, I do a bit of research, as much as I'm able to, given my time constraints. And, you know, and obviously, you know,
Starting point is 00:09:50 part of your big story is this sort of Nobel Prize thing, isn't it, you know? And I think that's really cool the way you've responded to that. And you've talked about the whole process and you've got a very, you know, you're sharing, you know, but it hasn't defined you. You know what I mean? There's a hell of a lot more to you than just that. But do you want to talk about a little bit about that? Sure. Yeah. As a young scientist, so my father, you know, was a professor, as I said, mathematics and a good,
Starting point is 00:10:16 and a, you know, very top-notch mathematician. And later he went into physics as well, foundations of quantum mechanics and all sorts of interesting aspects of physics that a mathematician could tackle. And we were kind of competitive, you know, here, you know, like many fathers and sons. And, you know, I always kind of wanted to outdo him. and win prizes and awards that he never won. You know, like you might do with your kids playing football or, you know, whatever you guys call it football.
Starting point is 00:10:43 We call it soccer. But playing football here, American football, it's often, you know, the father was, you know, captain of the football team in high school. And he's, you know, trying to relive his glory. And now here's his son. And they're trying to compete with these years. So we had that rivalry.
Starting point is 00:10:57 It wasn't the most healthy, but I knew for a fact he never won a Nobel Prize. So I knew he's closed. If I could win a Nobel Prize. permanent bragging rights, right? Yeah, yeah. And so that kind of led me down a dark path because it became, you know, in in, in Judaism, there's, you know, grave sin, which I'm Jewish. And the practice of idol worship is very common. And there are many different types of idols.
Starting point is 00:11:22 I mean, I've already mentioned a couple of them, you know, from YouTube subscribers to university professors to, you know, what college your kids go to, what, you know, how many subscribers you have on Instagram or followers. these are all idols, right? Money, obviously famous. But in academia, it's, you know, if you get 10 citations to a paper, as you know, it's, it's like considered a decent paper and a pretty well-regarded one. But, you know, the stakes are so, you know, small compared to all these other metrics that I think a lot of academics, such as myself, look to other ways of validation. And part of that validation was, you know, winning awards and prizes. And the biggest one of all, I mean, we're talking early, you know, mid-December. And every year on December 10th, which is Alfred Nobel's death day, you know, with these worshippers go to Sweden and bow down and
Starting point is 00:12:16 accept the gilded graven image with the visage of Alfred Nobel. And I mean, it couldn't, and it couldn't be more scatological. It couldn't be more, you know, kind of cultish. Yeah. But it's all in good fun, right? I mean, it doesn't really harm anyone except what it does, right? If you, if you look at it from the perspective of it determines, funding decisions. It determines who gets hired at universities. I was told by my department chair at the time when I was hired that whose father, his father had actually won the Nobel Prize for inventing a laser in Russia. He told me, well, we kind of hired you because we think you're going to win a Nobel Prize. And if you don't, you know, to disappoint a lot of us. So I was told
Starting point is 00:12:54 that in no uncertain terms, that was kind of the path that I was on because of the experiment that I co-invented when I was in this purgatory of being a postdoc at, Caltech in Pasadena where I spent three years. So that experiment was kind of designed by me and my colleagues to take the earliest baby picture of the universe using what's called the cosmic microwave background radiation, which is the oldest light in the universe, but it's not the oldest radiation if the universe began in a singularity, a big bang singularity of the kind that Stephen Hawking and Roger Penrose and others have talked about in singularity theorem.
Starting point is 00:13:33 The question of whether or not the universe had this explosive origin that came out of the result of a singularity or sort of a singularity in reverse. That was an obsession of mine that I designed the first experiment ever to tackle it. And that was in the year 2000 or so. And because of that. That's freaking unbelievable, Brian, isn't it? Yeah. You designed the experiment to detect the earliest freaking photons from the big, I mean, come on. Yeah, it would be great if we succeeded, right?
Starting point is 00:14:02 if we actually, you know, detected it instead of detecting microscopic rings. But even driving forward the technology in that direction, framing the problem, defining the concept. Look, we're still doing it now. And there's a huge component of the United Kingdom that's playing a big role. You know, Michael Brown at Manchester, my colleague Lucio Piccherillo. There's a UK, you know, investment of 20 million plus pounds to lead the observatory to double, you know, some of its capabilities in the next five years. And that's called the Simon's Observatory. The previous experiment I invented at Caltech that took us to the precipice of a Nobel Prize. And then, spoiler alert, my first book is called Losing the Nobel Prize. So, you know, that did not pan out in that sense. But yeah, you're right, to seek, to strive and not to yield, as the Lord Tennyson would say, right? And that's
Starting point is 00:14:48 actually on the plaque in McMurdo Sound, Antarctica, where the commemoration of the deaths of Roald Amundsen and his team is memorialized. So that, you know, kind of striking without yielding and striving without yielding is at the core, I think, of good science and adventure. And it's been, it's been incredible. And like I said, we're continuing, we haven't given up. In fact, the bicep kind of debacle in some sense led to the birth and eventual, you know, progress that we're making with the Simon's Observatory, which is about a $200 million experiment now. So this is just, yeah, beyond any of my wildest dreams for a kid in Long Island, New York who had a tiny little telescope looking at the craters of the moon back when he was 10 and
Starting point is 00:15:34 never thought, oh, this is going to be a job for me someday, right? Is that what really drove you, though? Was it sort of wonder at the majesty of creation itself and just what is going on? I mean, what sorts of questions drive you, Brian? What are you trying to find out? 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.
Starting point is 00:16:00 My connections stay strong even when the hive is buzzing. Plus, unlimited plans started $35 a month. Now, that's a deal that doesn't stay. Explore Google Fi Wireless plans today. Plus taxes and government fees. Google Fi Wireless is not subject to data traffic deprioritization during times of high network usage. You all, you're undoubtedly aware of the love affair
Starting point is 00:16:22 that physicists have for philosophers, right? maybe love hate you know actually yeah so i actually do love philosophy and i've always been interested in the biggest questions there are and philosophy is the entree into those discussions right so there's no there's no better place to kind of endeavor to understand the biggest picture aspects of of life and actually my hero of heroes you know is uh this guy galileo galilee you see my finger puppet of him holding a little telescope. And he used to say that the telescope had the ability to transform the vexations of philosophers into utter certainty.
Starting point is 00:17:03 In other words, you philosophers would speculate, what is the nature or makeup of the Milky Way galaxy, for example? And you talk about, you know, it could be this, it could be that. And then he could prove with his telescope, a little bit of confirmation bias that work, but he could prove that it was made of stars. and that's all it was. In fact, it's not, as I say. But the virtue of the philosophical questions being resolvable using instrumentation.
Starting point is 00:17:30 So I'm an experimental astrophysicist. I'm a cosmologist. I study the origin, evolution, composition, eventual fate of the universe, using tools and telescopes that my colleagues and I, my students, and I build, deploy, collect data from, and then analyze data, and then write papers. And this process can take 20 years. Yeah. Not uncommon.
Starting point is 00:17:50 So it's a long-term endeavor, but the philosophical core at heart has always been to only address the questions I find most interesting that affect the biggest picture topics in the universe. So origin of the universe, pretty big topic. And so I try not to get led astray by things like, you know, are there aliens? Are there life forms on other plants? As interesting as those are and as philosophical as those are, I have to stay focused, no pun intended, on what I can do uniquely. so, which is to measure and report on what we see. Right. I mean, reality is magical enough without these other phenomena, isn't it?
Starting point is 00:18:26 So, do you know what I mean? It's exciting enough to try and understand what our substrate is, you know, without aliens, man. That's right. But, you know, physics has become quite speculative, hasn't it? And, I mean, this reminds me a question that one of our members, Linton Cox, has raised. I haven't got the detail in front of me, but it's to do with, you know, has cosmology got a little bit like speculative philosophy? in some areas, and are there areas of it that just are simply not testable anymore, or is that unfair?
Starting point is 00:18:55 Yeah, I mean, I've sort of lamented the fact that a lot of what we do in the future of cosmology might be relegated to social proof, not actual scientific proof. And the reason I say that is of the dominant theories of cosmogenesis. So cosmology isn't necessarily, you know, required to come up with the origin of the universe any more than, say, an evolutionary biologist like my friend Richard Dawkins, and I'm sure your listeners are quite familiar with, I've hosted him here in North America. His, you know, he's not responsible for explaining the origin of life. I mean, he may be interested in it, and it may be extremely exquisitely, you know,
Starting point is 00:19:38 fascinating as it is to me. But it's not really a part of evolutionary biology on Earth necessarily, whether or not some enzymes formed on a comet that impact. the Earth, you know, 12 billion years, 10 billion, 4 billion years ago, it can't be older than the Earth. So the question of the origin of the universe is a very fascinating one.
Starting point is 00:19:59 It may belong, theories of cosmogony, may belong within cosmology. I certainly am obsessed with them. But the fact that we sort of treat them as sort of synonymous, that the origin of the universe, and therefore the Big Bang itself,
Starting point is 00:20:16 is sort of the default explanation When in reality, I've had a good friend of my Naish Af Shorty at Perimeter Institute in Waterloo, he wrote a book called The Battle of the Big Bang with a colleague Phil Hopper. And that book traces 32 different types of Big Bang. So it's a misnomer to say, you know, I often give talks, was there a big bang with the letter A capitalized? Because that to me is the real sorting point. Was there one Big Bang? whether infinite bang bangs, was there even a big bang?
Starting point is 00:20:51 You know, in other words, was there no big bang? And so the question of those may not be amenable to the Popperian kind of investigations, not that Popper is the last word either, but it certainly gives a framework. And in this case, you know, if you look for falsification as your rubric to assess the validity of a scientific claim, then you would have to say that where there are singularities, and event horizons, as there are with black holes and with the origin of the universe, uniquely. I mean, those are the only two binequely. I don't know.
Starting point is 00:21:24 There's two instantiations of singularities and advanced physics, and those are black holes and the Big Bang. Neither one of those can be witnessed, right? So those are enshrouded in an inscrutable layer of protection. So if we can't assess a model because we can never observe it and we can never acquire physical data from it itself and only have mathematical speculation and some corroboration that's circumstantial. What do we do? I mean, we can't falsify it and we can't prove it. So I'm drawn to models that make definitive predictions that can be disproven because at least
Starting point is 00:22:04 you can say something. The problem, though, Matt, is that you may not be in a position to ever have the sensitivity by instrumentation standards. In other words, even that theoretical perfect experiment because of certain limitations, we can talk about called the cosmic variance and the intrinsic uncertainty that we have in trying to make a statistical claim about a unique universe that we have access to. We may never be able to falsify the dominant model that predicts the singularity, and we may never be able to prove it either. So we're in this like purgatory of no man's land where we're unable to disconfirm or to
Starting point is 00:22:40 confirm. So what does science do in that situation? It's a very unusual time. And it's courtesy of the advancements in technology that my colleagues have really developed in our tools and techniques. I mean, that's certainly thinking as an experimentalist as opposed to sort of theory, because you have to engineer something that tests these claims. And, you know, there's almost, for me, you know, the idea that something can be engineered lends validity to the claims in and of itself, right? But I'm just thinking, you know, the conditions near a black hole just wouldn't allow for any testing equipment.
Starting point is 00:23:13 You know, this is the problem, isn't it? You need something half the size of the known universe to be able to do it or something. But is it possible, do you think this is a bit philosophical? Do you think that singularities, the Big Bang, is there possible that they represent more of the limits of our understanding or perhaps the limits of the mathematical modeling capability that we have within our gift? Is that possible? Well, certainly in broad strokes, both the Big Bang and Black holes have been comprehensible, you know, at least for, you know, hundreds of years.
Starting point is 00:23:44 in the case of black holes, maybe a hundred years in the case of a cosmological origin, a Big Bang. And that, you know, kind of was ushered in by LaMaitre in 1929. And then, you know, people like, they're scientists in England using Newton's laws to calculate the escape velocity from an infinitely massive object and found that it was, you know, even greater than infinite speed or would require infinite velocity. and that was before they measured the speed of light even. So there were concepts of black holes that were dark stars.
Starting point is 00:24:18 Mitchell, John Mitchell in the UK made up, you know, discovered these sorts of ideas. And then, yeah, the cosmological singularity. So we've been able to grapple with them and think about them. But seemingly, you know, philosophically, they're testable using, you know, thought experiments, get down and experiments and so forth. But in reality, yeah, you're right. can't actually approach them. Now, where they do provide some potential long-range signals,
Starting point is 00:24:48 as they do in the case of, you know, even hawking radiation, in the case of a black hole, or gravitational radiation from binary black holes. It's not the same as the event horizon, but we've imaged the photosphere, not actually the event horizon, but the photosphere around a black hole. It's a little technical to describe all the different, you know, black holes have, you know, as many different properties as, you know, the Brits have for naming, you know, breakfast items. I mean, there's just an R or tea or something. There's so many different, you know, qualifiers we get it to. But they did have, they do have an ability to exchange information with the outside world.
Starting point is 00:25:26 Therefore, we can hope to make measurable. Another thing Galileo said is let us measure what is measurable, but make measurable what is not yet so. And don't forget, he was a natural philosopher. They used to call physicists. They didn't have the word physicist until 100, 200 years later. But now he was called a natural philosopher. So, you know, he engaged in it. And the point is the ability of a scientist to make something amenable to our senses
Starting point is 00:25:54 is a crucial part of the scientific method. I mean, without it, it's pure math. And I don't think there's anything wrong with pure math. But you're right. There are precious few things. And therefore, when nature affords us, you know, a peak under her veil, or lift up the curtain, we should take advantage of that and use whatever tools we can. And in the case of what I do, we don't use the, we can't use light because, not just because
Starting point is 00:26:20 the universe didn't have the types of light that we're looking at right now at each other. It was microwaves, but, or it is now in the microwave region. But because the process by which the elements, you know, on the upper left of the Puroct table form, the helium, hydrogen, and so forth, when they form, they obscure the processes that came before them. So essentially it's like a fog. Like here in San Diego, the only kind of malevolent weather we get is in June.
Starting point is 00:26:49 We get something called June gloom, which is usually preceded by May Gray. And this is a low layer of basically coastal fog. And it's caused by a different temperature between the ocean and the surrounding land and the condensation. And so I can't see an airplane flying 10,000 feet above me, but I can hear it. So if we use something other than light, we can see, we can see, quote unquote, perceive things other than what produced that light and what came before what produced that light.
Starting point is 00:27:19 So when you look in cosmology, you look back in space, you look out in space, you're looking back in time because of the finite speed of light. So we look back to a time before half a million years after the Big Bang. And that could be a singularity. It could be a previous cycle. It could be a variety of different things. but some hot dense phase of the early universe. If we try to look earlier than 500,000 years or so, we can't use light.
Starting point is 00:27:45 We can only use other types of radiation, and there's only two other types of radiation that are long range and could potentially provide a signal, and those are neutrinos, which are notoriously, you know, nearly impossible to detect and, you know, interact only weekly and via their gravitational effects. So they're not really that great. But actually we want to go back and use waves of gravity, gravitational radiation.
Starting point is 00:28:09 And so if inflation, which is the theory that a quantum field fluctuated into existence, the energy density needed to ignite the big bang, then it would have also concomitantly produced gravitational radiation, which would exist before the cosmic microwave background earlier times, at time equals, you know, tantumized 36 of a second after the origin of our observable universe. we seek to measure that signal via its imprint on the light of the microarray background that we can see via what's called its polarization, which is a lesser-known property of light. But we can do it, and we measured a lot of the polarization of the CNB exquisitely accurately with experiments, including Bicep and the Simon's Array and now the Simon's Observatory. But we have yet to measure definitively that is without contamination a cosmological signal. With Bicep, we did measure a polarization signal that exactly mimicked what the inflationary epoch would predict. And that was called the B mode polarization of the C&B.
Starting point is 00:29:12 But that was produced by these microscopic grains of dust, these actually microscopic meteorites, not unlike the kind you can get at my website if you're in America. Unfortunately, Matt, I'm sorry. I can't ship. I tried to ship to the UK, and I do bring them when I go over to see. I was at Stonehenge this past summer in Manchester and Scotland. So I brought a bunch of meteorites with me. But the U.S. Postal Service will not allow me to ship them to the UK.
Starting point is 00:29:35 But if you're listening, anywhere else, go to briankeating.com slash x, and you can be entered into it. Unless you're an academic, like me in the U.S., then go to bryankeating.com slash edu. And I'll definitely send you one of these meteorites. So these are four billion-year-old objects that were present before our earth formed from the preceding star that occupied this corner of our galaxy. I love that. These micrometeorites get magnetized in the Milky Way's magnetic field, and they can align like little tiny compass needles. And they produced the polarization signal that exactly mimicked what we thought we had seen with the CMB. So this was an incredible kind of detective story.
Starting point is 00:30:17 But in the end, yeah, it resulted in a disappointing, obviously disappointing. And wanting, you know, kind of to be helpful without having a sense of confirmation bias. So it led to a lot of things, yeah. Yeah, yeah. What were you doing down at Stonehenge? That's literally just sort of 50 miles away from me. Oh, is it really? Yeah, were the druids?
Starting point is 00:30:39 I went there, yeah, it was around, it was in July. I was trying with my family. I'd never been there. I felt like an astronomer should, you know, spend some time there and hang out there. And so I went there with my family. I did a video on my YouTube channel. It's actually called from Stonehenge to the spirit, space age or something like that.
Starting point is 00:31:00 So I went from there to Jodrill Bank in Manchester. So is it an astronaut? Is it a clock? Your summer starts now with Memorial Day deals at the Home Depot. It's time to fire up summer cookouts with the next grill, four-burner gas grill on special buy for only $199. And entertain all season with the Hampton Bay West Grove's seven-piece outdoor dining set for only $499.
Starting point is 00:31:26 This Memorial Day get low prices, guaranteed at the Home Depot. While supplies last, price invalid May 14th of May 27th, U.S. Only exclusions apply. See Home Depot.com slash price match for details. Well, it's not clear. There are certain astronomical attributes of it where it does have these alignments.
Starting point is 00:31:44 And the question is, you know, if it aligns with stuff now and it was built 5,000 years ago and do the procession of the Earth's axes, you know, where did it align? When did it align when it was built? There's a great deal of mysteries about it. I think it's safe to say it was used, you know, in conjunction with, you know, with observations of astronomical objects as, you know, four thousand, five hundred years later, you know, if you went to Tico Brahe's island, you know, off the coast of Denmark, you would also find these things or north, north, the North Sea, wherever he was.
Starting point is 00:32:20 He basically had this kind of similar thing with like, basically built this giant chair on a protractor where he could slide up and down and look at the positions. And he was the last naked eye astronomer. And so there are similar things that line up there on his observatory. And so, yeah, there's quite likely it was used in part for that. You know, how it was built is a great mystery too. We don't really understand. I mean, you know, what else is there to do when it's dark other than just sort of look up? You know what I mean?
Starting point is 00:32:46 Supposedly, like the mounds, you know, the earthworks is actually even more impressive. I mean, it's a huge structure. The stones are very small. I was very disappointed that they didn't let me touch it. I guess they knew my kids are not to trust. So I ended up going through it and taking a drone with me and flying around it. But I wasn't able to get up and actually touch it. So that'll have to get special permission someday.
Starting point is 00:33:15 But have you been to Glastonbury? No, I know there's another one there. Yeah, yeah. The hippies and druids say that it's on a network of laylines and there's this magical sort of property there. And it does seem like a magical town. Yeah, it's a fantastic place. place. Oh, okay.
Starting point is 00:33:29 Next time you're in the area, go to Glastonbury. That's an amazing place. Okay. But I've got some, because I'm just a little bit conscious of time. Yeah, yeah. But some of our members' questions are so much better than the ones I came up with. So I'm just going to, I should have just led with them, to be honest. But, yeah, so here's an interesting one.
Starting point is 00:33:49 In pursuit of, so this is from Linton Cox. So Linton is our brain box. He said, I like Keating. He's thoughtful. From Linton, that's absolute. I appreciate that. That's extremely high praise from him. But he said, in pursuit of fundamental truths about the universe,
Starting point is 00:34:05 scientists often endure extreme stress, failure, and isolation. Do you think the culture of heroic science sometimes sacrifices mental health or ethics for prestige? Well, you know, again, consulting my friend Galileo here. He could say a thing or two about it. I've been to Galileo's, you know, final resting places prison outside of Florence, Italy, called Archetri. I've had a conference there. about the theory of relativity
Starting point is 00:34:29 on its 100th anniversary of general relativity because a Galileo came up with Galilean relativity, which is basically what happens if you're on a boat and you throw a tennis ball or whatever. And he thought about these issues very deeply 300 years before Einstein would come back. So it does, it can, it certainly can. I mean, I think it was more common
Starting point is 00:34:50 in the heroic age of exploration and of intellectual pursuits that people would be driven to these kind of, you know, manic, you know, modes of operating. And certainly now, you know, in modern age, when it's impossible, I say with pretty high confidence, it's almost impossible, if not maybe it's strictly impossible, for a single scientist to do anything. Yeah. I mean, there are no, you know, Einstein, you know, and without an at all after it. because the low-hanging fruit is gone, right?
Starting point is 00:35:26 A lot of the low-hanging fruit is gone. There are new discoveries being made and serendipitous things all the time, but those are made by enormous instruments like the dark energy survey instrument or the Vera Rubin Observatory, the James Webb's-based telescope. You know, these are enormous billions of dollars
Starting point is 00:35:43 of the Large Hadron Collider. You know, these are just enormous super cameo-candhi. So it's essentially, and another way to see this as someone who does study things like the Nobel Prize is that there hasn't been like a single winner, a lone winner of the Nobel Prize in many decades. I forget the exact last person to win it solo. But it was very common, you know, 100 years ago or, you know, it's been around for 124 years now. So it was very common or, you know, much more common. but now it's basically, you know, kind of huge collaborations, and then people get all mad because, you know, LGO, or LHC had 5,000 people that discovered the Higgs boson, and yet, you know, at most three people can win it because of their refusal to change their rules and their obstinence, the Swedish Royal Academy of Sciences, which I've had the honor or whatever, the shame of nominating winners for the Nobel Prize.
Starting point is 00:36:42 And that's why I kind of went off on this quest to see, does it really? represent how science is done nowadays you know maybe it was done that way 124 years ago when when William Renkin invented the x-ray you know and that did provide a single person in the previous year who conferred the greatest benefit on mankind but you know seven years after that there was Gustav Dallene who invented the lighthouse regulator for buoys and and so you know does that really affect you over there you know I know in San Diego I use lighthouses instead of the GPS to get around, but I'm unique.
Starting point is 00:37:19 So, yes, to answer his question, I do believe that that epoch is mercifully coming to a close if it really does exist anymore. Because of these, now, that's not to say that there aren't a tremendous number of people that aren't tortured. You know, I get dozens of emails. I'm looking at emails I got, you know, yesterday, the day before, people writing me, Professor Keaton, you know, I need your help. Here's this paper I've written.
Starting point is 00:37:44 I've checked it out with ChatGPT. ChatGPT agrees with me. It's brilliant. It's going to change the world. It's going to resolve the black hole information paradox. It's a new theory of everything. It breaks the second law of thermodynamics. And this is just one paper, right?
Starting point is 00:38:00 I get five of them. And they all say the same thing. Like, I've checked it out with chat GPT. They have no awareness that that's what these things are designed to do. Because if they don't, the user experience is horrible. If you use a thing that says like, you're an idiot, Matt, you know, Brian, you should not be. like submitting this drivel. Like I have a lot of ideas too, but, you know, not a lot of them would pass muster outside of chat GBT. So it's been a real boon to people working alone. And therefore,
Starting point is 00:38:27 it's encouraging a lot of them to, you know, perceive themselves as having this lone genius, you know, resurrection from the bygone error in which it harmed people's mental health. So I do worry about that sycophanty attribute of them and the hallucinations that come along with it. So it may come again, but in mainstream science, less so. Yeah. It's not healthy unlocking yourself in a dark room for five years and coming out with the theory of everything. It's just, you know, we're done with that.
Starting point is 00:38:56 It's a social network now, isn't it, inevitably, you know? That's right. There's another question here. So, oh, yeah, this points to cosmology, the speculative philosophy. I mean, have you ever worried that your own work approaches that boundary? Of being a lone genius? No, I don't. Well, no, no, no.
Starting point is 00:39:13 Your mother-in-law will make me clear. You're a sociable genius. Yeah. But have you worried that your own work might be approaching speculative philosophy ever? Speculative, no. I would say that what I try to do always my philosophy of experimental cosmology is to do always never do one thing. Okay. So, and that means in the following sense, if you build an experiment, it should at least be able to solve,
Starting point is 00:39:43 more than one problem. It should solve at least two problems. In other words, not only look for the origin of the universe. So the Simon's Observatory is the ability, or let me just go back to Bicep. So Bicep was a failure, right? It was, I mean, I know you said a lot of nice things about it. And I agree with you. But I'm just saying, you know, a cynic could say, oh, it was a failure. It cost 10 millions of dollars. You made this huge announcement. It was on the front page of the Guardian, the New York Times, the San Diego Union Tribune. It was on CNN, NBC, NPR. And then you how to retract your claim, right? Okay, so fine. But look what else it did. It also showed us that the galaxy is incredibly messy, dirty, filthy place. And I was going to say like New Jersey or Los Angeles
Starting point is 00:40:26 here, but I'm sure you've got, what's your neighboring town that you hate that your football club? That's your rival football club there, Matt? What? I can't believe you told you got me to say it, Gloucester. Gloucester. Okay, good. All right, those buggers at Gloucester, okay? Let's look at them, Okay. Savages. It's a filthy place, right? So the galaxy is like Laster, okay? It's full of dust and smog and soot and grime and a bootlick should never even set foot in it, right?
Starting point is 00:40:54 Matt, I mean, no person would be there in their right mind. But we learned about that so much so that there's huge careers and new studies about the galactic galactic chemistry, cosmo chemistry, even tiny particles, your, you know, countryman Fred Hoyle was a big believer. that meteorites carried life to the earth and perhaps that it could cause a you know the the flourishing of life due to what's called panspermia carried on meteorites so now we've learned a lot about you know some of the parameter space so this is all to say we set out to do one thing but we did something much more practical and of course we would have preferred that we didn't do the practical thing and learn so much about dust right it's it's like uh you know a lot of things
Starting point is 00:41:37 in life you'd prefer to be ignorant about maybe but now that we know about it now it's informed all these other experiments like the Simon's Observatory and how to optimize it. So we won't make that mistake. And that's what science is. Science is a process of always being wrong, but quantifying how wrong you are. So I don't worry about that. So even in my experiments, you know, that are going after similar topics, no, I always make sure that we're able to do many other things, including some things that on their own
Starting point is 00:42:03 would also win a Nobel Prize. Like, for example, one of the things that we can do with the Simon's Observatory, that for technical reasons we couldn't do it by some, is, look for the impact of neutrinos, these massless particles, near massless particles, they have a tiny bit of mass, but they're the only form of dark matter that we know exists for sure. We may detect what they're actually made of and how they behave and what their masses are. That would be a huge achievement that no one's ever done in history. We may detect planet nine, you know, the ninth planet in our solar system, another huge thing that could be done
Starting point is 00:42:34 with this. So there's like 45 or 50 different things that I can do with this experiment that And only one of them, or I'll say two of them, because I have another one that's very speculative, called searching for Lorentz invariance violation. But if either one of, even if either one of those two don't pan out, so to speak, which were the main reasons that we built the instrument, we are building instrument, but we have 48 other consolation prizes that are each, you know, in some sense, worthy of the greatest prize you can imagine. Brian, something that just occurred to me because you've spoken to so many guests.
Starting point is 00:43:08 I mean, what was it? You said sort of 30-odd Nobel Prize-winning guests. You've had such a play, 22-12, sorry, man, but you've had such a plethora of different opinions on philosophy, the nature of reality, mysticism, even in cases, you know. So has this informed your own sort of metaphysical outlook? And, you know, or can it make you, I mean, sometimes for me, being exposed to all of these deep and sort of complicated ideas, it kind of drives me a little bit crazy. You know, and sometimes I can't sleep for days, you know, after researching some of this stuff. So I don't know, just how has it impacted you as a person and does it change the way you think about reality? Well, you know, I do feel, you know, I have an unusual for, you know, professional cosmologists. I think I have an unusual curiosity.
Starting point is 00:43:53 And I have an outlet for that in that I have this podcast that I can talk to people about very speculative things from philosophy, to AI, to, you know, extra solar life to cosmology, theories of everything. the philosophy of cosmology. I would say for me, you know, it's less sort of philosophical crises or conundra that I suffer from, but it's more than I get pulled in so many different directions.
Starting point is 00:44:21 I'm so interested, I'm so acutely aware of the finitude of life. And I'm so torn by wonderful distractions in my life, you know, called my kids and my wife and my family that, you know, I don't really suffer from that. You know, it's, it's said that a man like, you know, who has to hunt his own game for food every day and, and some tribe somewhere, you know, he's not really having a metaphysical crisis, right? For me, it's more the, you know, kind of the, the battles that I have, you know, and I've come to be, you know, if I, if I suffer from any kind of crisis of confidence, it's been the, it's been the recognition.
Starting point is 00:45:06 that science can sort of, you know, have a little bit of too big of a notion of its own importance. And I think the way that this manifests itself is that most scientists, myself included, or most – let me say most professors, myself included, are, you know, kind of important but not significant. And I'll say in the father, we're like, we're important because we train the next generation. We contribute a novel thing. But we're not like – we know we're not significant. get like we're not changing social policy like my colleagues are all mad at trump you know for example cutting all these funds and so they can't do anything about it like there's no way they can do it
Starting point is 00:45:43 so they take out you know their rage and online and and so forth and you know it could be sympathetic to it but but the point is they know that they can't really affect any change as a scientist nor really i mean i wouldn't want to be led by scientists and and and and paul instead of politicians i wish the politicians had a better grasp of science but the degree to which the scientist and professors, more professors. I mean, some of the dumbest ideas come out of academia. And almost any, you know, kind of thing that's preposterous to believe, you know, could never be, you know, foisted upon my friend who's a gardener or something like that. But, you know, my academicians will start to think about, you know, these things in great detail. So I think that's because we have this
Starting point is 00:46:26 luxury of, you know, being paid to think and having tenure and permanent employment. And so we don't, we've lost sight of the fact that we have. have customers, the customers are the public, and they pay our salaries no matter what you are if you're at Harvard, a private institution, I don't care, you're still supported by public funds. And to the degree you alienate your customer by saying they're not intelligent enough to grasp the brilliance of your arguments, then you risk your livelihood. And I think you should. I think it's quite right that the public should demand accountability from scientists as well.
Starting point is 00:46:57 And we saw a tremendous failure of that, obviously, during COVID and many other instances where people have been kind of led down the primrose path. So I do feel like I don't have any major, you know, major, you know, kind of metaphysical crises regarding cosmology, but I sometimes do when I think about the profession of being a cosmologist. So those are distinctions I like to make.
Starting point is 00:47:22 You say 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.
Starting point is 00:47:39 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. Right. What's your position on religion then and God, if I may ask, Brian?
Starting point is 00:47:58 Because somehow the last sort of 20, 30 years it felt traditional that science was about materialist atheism and it would seem contradictory somehow to sort of go to church and believe in the black, you know, the big, big bang and all this. But these days, not so. I mean, I was chatting to Philip Goff recently. He said, he says he's, what is he, he's a heretical Christian,
Starting point is 00:48:17 you know, and he's made a home in the Anglican church who are very metaphysically cool and progressive, you know. So, and I'm kind of quite mystical these days, having come from quite a sciencey maths and computational background. And it seems, like everyone seems to be on a journey these days. with this is quite a lot of metaphysical traffic, you know. So where are you with this stuff?
Starting point is 00:48:37 How does golden physics work? Yeah, I mean, I like to say that, you know, science, the word science, you know, comes from Latin Ciencia, which means knowledge. And, you know, my phone has a lot of knowledge. And, you know, chat, TBT has a lot of knowledge. It has no wisdom, right? What we really would like is artificial wisdom. Like, you ask a question, you don't want to get like 10 different links or 10 different opinions or say you're so brilliant, Matt, for, you know, wondering where you can get the best,
Starting point is 00:49:02 you know, blood pudding for, you know, Christmas breakfast, you know, bangers and mash. I would say like the quest, you know, I gave a talk at the Royal Institution, which was, which is incredibly fun. And I put up, you know, the big controversy is, you know, is if you have a big bang, you know, who's the big banger? And I put up a picture of a bangers and mash, as you call it. And the crowd went, went, just briefly, there's a great lyric from a Frank Zappa song. It says, Lord have mercy on the people in England and the terrible food these people must eat. And such small portions, man.
Starting point is 00:49:37 Yeah, yeah, yeah. I'm there, it's terribly small. I'm an American. I need a big banger in the morning. So you're right. And this has always been, I mean, Fred Hoyle coined the term big bang, and he did it as a pejorative because it smacked to him of religion and a creation and so forth. So I think it's natural, and certainly you can't falsify the existence of a God,
Starting point is 00:50:00 but you ask me, like, personal. Like, I always say, I don't. believe in God the same way I don't believe in gravity. Like I have evidence for gravity, but God is sort of much more inscrutable. I mean, as I said earlier, I'm Jewish. I call myself a deeply very orthodox practicing agnostic. And I think agnostic in the sense that I'm searching, not in the sense that I can't know. Like my first guest on the podcast was, again, your late great countryman, Freeman Dyson. And Freeman and I used to talk about religion. And I said to one day on a podcast. I said, Freeman, you call yourself an agnostic, but imagine, you know,
Starting point is 00:50:37 hyper-intelligent alien species watching you on a Sunday morning. They look at you and they look at your neighbor, Richard Dawkins. You both don't go to the same church, right? You both stay home, right? You both don't do the same thing. So how do you distinguish yourself from an atheist? Are you just copping out and saying you're an agnostic so you don't, you know, he won the Templeton prize, which is given for, you know, religious, you know, kind of philosophy and writings and so. So he didn't really have a good answer. I mean, I love Freeman. I miss him a lot. He used to visit here and see me and come to my house in the winters from Princeton. But, you know, he didn't really give a great answer. I think a lot of it comes down to the fact that if you were to believe,
Starting point is 00:51:21 then you have obligations, which you don't have if you don't believe, right? So if you do believe even one of the standard monotheistic religions, at least, the only ones I'm familiar with, then you have certain obligations. So I practice Judaism. In other words, I keep the Shabbat, the Sabbath. I don't work on it. I don't send emails. I don't do podcasts. I don't, you know, I do things. I go to a temple. I keep kosher, you know, to the letter of the law of kosher, not, you know, perfect kosher, I'm sure. I fall short of what a rabbi might do. But these are kind of healthy things. These are really healthy things.
Starting point is 00:51:59 I reckon a day without technology would be a great thing for me, to be honest. Oh, it's a wonderful thing. Yeah. I mean, people are talking about it all the time. Even non-Jews is a sabbatical. I mean, we have the word sabbatical in academia for the very thing that you get refreshed, recharge by changing, slowing down and manipulating your reactive monkey mind. So you don't have to always be, you know, in pursuit of the next shiny object in academia,
Starting point is 00:52:20 which is plentiful. So I think that there's a great deal of wisdom in religion. it may not be, you know, knowledge. It may have zero scientific knowledge. I mean, the Bible, the Torah, which I study, and I read Hebrew fluently, and I study the Talmud and all these other documents and religion, it's very clear. The sun and the moon are created on the fourth day. And so you're like, well, what does that mean?
Starting point is 00:52:43 Like, how could it be possible that they didn't know what a day was back in, you know, the day was caused by the orbit of the sun around the earth, right? They're so stupid. They're so primitive. But when you, if you take off the Sam Harris, and I've debated Sam Harris about this on my podcast, which is not very pleasant for either one of us. I've not actually seen that one. I should go and check that out. Oh, yeah, yeah. It's three and a half hours. It was supposed to be one hour. We were having such a good time. I said, Sam, I know your producer said you only have one hour. Can you go longer?
Starting point is 00:53:12 We went for three and a half hours. And then at the very end, I asked him, you know, about, he made a statement about, you know, slavery and how illogical the Bible is and how he and I in five minutes could come up with a better document. in the Bible. And I started to kind of gently, you know, nudged him in a respectful way, but I don't think he liked that. And he, so far as not shown willingness to come back on my podcast. But that's okay. I'll need to talk to him once. But the point is, even if you, if you don't have such a jaded cynical hostility towards a religious document, and look, I'm Jewish, I can read the Koran. I mean, I've, you know, I don't have a hostility towards it. I can read it as a religious document. I was an altar boy in the Catholic Church in New York. That's a
Starting point is 00:53:54 other thing I've done. You know, I can read these documents that I don't practice and I can react in a respectful way. I talked to John C. Lennox last week. It was a lovely guy, a very devout Christian, as you know, maybe, a Christian apologist and mathematician of the highest order at Oxford. You know, he and I talked about, you know, some of my challenges that I have for him when it came to things like the ascension of Jesus and the resurrection from a physicist's anyway. But the point is, if you can talk respectfully, then you could know that, for example, you'd be willing to the open to the idea that at least when the Torah, the Bible, the Old Testament says the sun is created on the fourth day, it's doing that for a
Starting point is 00:54:34 reason that has nothing to do with science. And you're an idiot if you read it as a scientific interpretation because you're only trying to substantiate, you know, and straw man it. But the way, and I'll just say for, you know, a lot of Judaism is centered on the exodus from Egypt, where Jews were documented to have been slaves in Egypt and the number and the exact nature of the Exodus. We can debate that scientifically. I don't really care about that. But the point was when the Torah was written by, you could say, men, multiple people, you could say by Moses, whatever you want, the dominant culture of the time, the superpowers, there were two superpowers, it was Babylonia and it was Egypt. And those two powers were at war. And what did they both worship as their key,
Starting point is 00:55:14 you know, sustaining, you know, godhead? It was the sun. It was in both cases, it was the sun. And the second God was the moon. And even in Arabic words, you know, the, the, you know, notions of these things are present still hundreds of years after Jesus lived. So the Torah is coming to tell us that these things that we say that nature was created. So therefore, don't worship nature. And the Torah's plenty hard on Jews and people that, you know, purport to believe this and be sanctimonious and so But what I'm bringing up is that the Torah has some wisdom in it. And if you just suspend the fact that you're always looking for knowledge, knowledge is abundant, but wisdom, you know, to kind of paraphrase Einstein in circles the world. If you can have wisdom, I'd much rather have R-A-W than AI.
Starting point is 00:56:03 You know, I mean, there's plenty of AI, but there's very few people I consider why. So that for me is the reason for at least my own personal, you know, resuscary. or resurrection to mix metaphors and mixed religions of of this interest that I personally have. I find it fascinating. It's such a rich thing to study. And people that dismiss it as, you know, Bronze Age, like our friend Lawrence Krauss now, you know, semi-discraced here in America because of his involvement we've learned with Jeffrey Epstein. Oh, cronky. But, you know, he used to say, you know, his Bronze Age peasants.
Starting point is 00:56:40 but you would never say like, you know, that, well, you know, Archimedes was basically just, you know, post-Bronze age, but, you know, and Aristotle sure did get a lot of things wrong about science. I'm going to say the Precicracics were quite a bright bunch as well, you know. Yeah, exactly. Plato, right. Yeah, yeah, yeah. We wouldn't want to emulate them. So anyway, Matt, that's sort of where I'm at. I do find that there's potential for meaning.
Starting point is 00:57:05 If you grow up without it, though, if you grew up with a parent, as I did, who is a, a devout atheist who hated religion, never set foot in a temple or a church, you know, then I think it's very hard to at least be open to the idea that religion can provide you meaning, let alone believe in God, you know, whatever that means. I don't, like I said, I don't believe in God. I don't think God is like upstairs in a white beard. But, but, but, and that's where I have things in common with Richard Dawkins, you know, and he and I can talk about that. Yeah, yeah. But, but, you know, at least it has to be done with an intellectual honesty. And, and I find that's lacking from people like Sam Harris and others.
Starting point is 00:57:40 Yeah. You know, in some sense, they're more absolutist than sort of the mystics. You know, I mean, for me, for me, atheism is one of the most fundamentalist positions you can get. Oh, yeah. Because there's almost no one. You've just told us that we can't prove one way or the other whether there's a
Starting point is 00:57:55 God. And now you're telling us there certainly isn't one. I mean, I think one of the chapters in Dawkins' book, The God Delusion was actually entitled why there almost certainly is no God. Right. And that was before the chapter where he looked for this thing in the brain called the God Spot, was responsible for all of our mystical experiences
Starting point is 00:58:10 and all this kind of stuff. I mean, you know, it was fashionable back then. I remember I've been on this kind of journey. I was raised to Catholic myself. My parents and aunts and uncles didn't have a great experience with Catholic school and they were like whips and beaten by nuns and things like this, you know,
Starting point is 00:58:24 so it was pretty harsh, you know, very Victorian kind of mentality in some of those places. So I, you know, I drifted away from it. And it was like me and my mates were just down with Richard Dawkins, Stephen Hawking's, all the scientists, that kind of stuff. these guys will have all the answers, right?
Starting point is 00:58:40 I remember there was a time in sort of mid-90s where we thought, you know, we're going to get the unified field theory, you know, we're going to unite, you know, sort of Einsteinian mathematics with quantum field theory and all this kind of stuff, and we're going to get them, but we haven't, have we? We haven't fine. So when will we get everything? I mean, I spoke to Jenny Nielsen, who's also another, she's a practicing Catholic. So she talked about mysticism, religion, and also the physics.
Starting point is 00:59:06 But have you come across her work? She's working on a topological unifying. She lost me at fiber bundles, but she's a very interesting character. Oh, yeah. Yeah, yeah. Well, if she has any books and interest in coming on my show, I'd like to talk to her. Yeah, I haven't encountered her at work. But to answer your question, yeah, there's been this, you know, kind of consistent search for it.
Starting point is 00:59:29 And even in Stephen Hawking's, you know, most famous of all books, a brief history of time, he says at the end, you know, when string theory, you know, turns out to be the theory of everything for quantum gravity and the reconciliation of the quantum with the macroscopic gravitational. But notice he said when, not it. Yes. Yeah, it's basically when. Then we will, then we will know the mind of God. And obviously, he was an atheist. And his wife at the time, you know, he's a very sordid person, by the way.
Starting point is 01:00:02 Not to like denigrate his memory, but he had a, there's a book written by Charles Seif, was a professor in New York University called Hawking, Hawking, like selling hawking. And I do remember going to a speech that he gave at the Royal Academy, and he could still respond to questions in 1995. You know, it would take 10 minutes, but he would type out with his eyes, you know, amazingly. And he was certainly, you know, inspirational in that sense. But someone in the audience said, like, you know, Stephen, why did you write a brief history of time? Like, it's rumored that almost nobody has ever gone all the way through it. And he said, very slowly, I remember saying, because I needed to pay for my daughter's private school. You know, it was very funny. And, but yeah, at the end, I think he had this battle with his wife. And he says in the book that every equation cuts the readership by half, but every mention of God doubles it. So he was trying to kind of play these forces off of each other. I don't think he was cynical about it, but I think he, you know, I think he truly, and I don't fault him.
Starting point is 01:01:06 I mean, God forbid, I mean, I shouldn't say whatever, Zeus forbid, you know, that anybody's in that state, but, you know, they might justifiably have violent, you know, kind of beliefs if God exists, why did they do this to me, right? But I think if you look at God as a celestial butler, you know, if you look at them as just this wishmaking, you know, slot machine that just, of course you're going to have a childlike view of it. I mean, Yuri Gagarin, the first man in space, when he was interviewed, he said, as soon as he landed, like, they asked him, what did you see up there? He said, well, I know what I didn't see. I didn't see a man in a white beard. I don't believe that there's a guy in a white beard floating at 200, you know, kilometers above the Earth's surface. I don't believe that either. I think it's stupid.
Starting point is 01:01:47 I think it's childish. But the question is, what is the fruit, you know, as Jesus said, you know, judge the tree by its fruit. And so what do these religions produce? So I'm not going to speculate, but look at what Judea. is contributed, like in Christianity, look at Islam, look at the different contributions, and then look at atheists. Don't not look at atheism, but you have to look at like, are these people generally happy? Are they generally promoters? You know, because the, you know, the
Starting point is 01:02:15 Fourth Commandment, sorry, the Third Commandment, is, you know, don't carry the name of the Lord in vain. It's not really clear what King James meant by all these things. But in Judaism, it means like don't profess to be religious and and do things wickedly by the excuse of the fact that you're doing things godly. But also don't like ascribe like your personality problems and your traits to my religion. You know, basically if you want to be a good ambassador for the religion and you're in, you know, a horrible mood and you're an unhappy person, you might want to think of another religion, right? So, yeah. I don't be grumpy with them.
Starting point is 01:02:58 Exactly. So I do feel like there are very important questions to answer and to think about, but you have to be comfortable knowing that you won't get cognitive closure on all these things because they're not epistemically amenable, right? There's no microscope that will find God. I've had debates with people, even like John Lennox and Stephen Meyer and Christian apologist. And they can be guilty of cherry-picking. certain things too. So I do believe that there's, you have to be humble, epistemic humility,
Starting point is 01:03:29 and that we won't have necessarily ever have all the answers, Matt, but the point that we have to always remind ourselves of is that we must not, you know, shy away from the pursuit of, of attempting to answer them. We may never answer them, but don't step away because it's too hard. I love that. That's beautiful. But could I just, I mean, do you think that the sort of deterministic mechanistic stance of scientism, if you like. Is that softening? And there's new players in town now.
Starting point is 01:03:59 In neuroscience, you've got people like Donald Hoffman talking about consciousness being fundamentally. You've got emergence of different metaphysical systems. Philip Goff talking about panza. Apparently 33% on Phil papers now, 33% of the philosophers published there are now non-materialist, you know,
Starting point is 01:04:15 and that figure seems to be going up. So are we going through a kind of Thomas Coon-style, you know, paradigm shift in science writ large? physics? I mean, what do you think? It could be. I mean, I don't, I don't have my, you know, kind of finger on the pulse of that, you know, kind of ideological or philosophical, you know, kind of a universe, to be honest with you. But in my own, you know, sense, I do believe that there, there is no meaning in science. Like, science is a beautiful thing. Just like, I don't think that there's a meaning that you can ascribe to life from pure mathematics, where you can actually
Starting point is 01:04:52 at least prove some things. You can't prove everything as girdles showed, but you can prove some things. You can't prove everything. But in science, we can't prove anything. I mean, there's no saying that gravity won't be negative tomorrow due to some modification of dark energy, right? So there's no provable fact, right?
Starting point is 01:05:08 Because we can't falsify all the alternatives. So in my sense, that means that you shouldn't look for meaning in science, which is fine. I get meaning for my job of being a scientist, but I don't find meaning in like, well, here's this, you know, star with a certain, you know, magnitude and color diagram. You know, okay, it's an interesting fact. But I also think it's dangerous to kind of go, you know, too far on the other side and say that,
Starting point is 01:05:35 you know, everything, as John Lennox might say, you know, like everything is guided by not only religion and God, but, but Jesus Christ himself. I mean, that, as I told him, you know, like, I don't, you know, we, Jews don't. subscribe to the fact that Jesus was, you know, the son of God and that he was the Messiah and all these other things that John believes in. On the other hand, you know, there are lesser claims that we do establish and we do believe in. So I think that that, but does that mean I can't get mean? I already quoted from Jesus a few times today, right? So, you know, one of my favorites is don't, you know, don't criticize your neighbor for the mote of dust in his eye when you have a log in
Starting point is 01:06:19 your own eye, right? I love that. That's not Jewish. That's Jesus, right? So, and the dust, as I said before, go to Brian Keating.com. And you can get your own piece of dust, Matt. So I'm, you know,
Starting point is 01:06:31 kind of a pragmatist. I come from the school of, you know, shut up and measure, you know, and the philosophical interpretations. I just got done teaching quantum mechanics to advanced undergraduates. We don't spend much time on, you know, interpretations of quantum mechanics.
Starting point is 01:06:47 But in another sense, it was very delightful to, you know, encounter these things and be able to measure things to 13 decimal places. That, to me, is a beautiful thing, but it's not meaningful. Gosh, that's actually quite, I wasn't expecting that, Brian, from a physicist, because I'm thinking, you know, if you've got two different sort of sub-disciplines of mathematics or physics that arrive at the same number and things like that, there's something so beautiful and profound about that, isn't there? You know, wasn't the speed of light arrived at slightly differently, through studying electromagneticism and things like that.
Starting point is 01:07:21 Was it Faraday? I'm not sure. Well, yeah, I went to, yeah, well, certainly I spoke at the Royal Institution where Faraday was, and that was incredible. And I had his actual original equipment, and he was the one who came with the lines of force and force fields and that whole concept. And then- You had his original equipment there?
Starting point is 01:07:36 You had his, that's the- Yeah, I actually used his original, like, iron filing suspended in the last. It was incredible. Yeah, you can find it on their YouTube channel. That's cool. A hundred thousand views or something by now. But no, I went to Maxwell's, I haven't published this video yet, but I went to Maxwell's birthplace on India Street in Edinburgh, and I went to the Royal Observatory of Edinburgh and
Starting point is 01:07:57 did some videos and interviews there. And no, it was incredible what he, but look, this is a perfect example of how, you know, science and wisdom like don't really go hand in hand. So imagine Maxwell had this idea for electromagnetic radiation. He proved it, thanks to Oliver Heaviside and others, that it actually was these four equations then could be unifying electricity and magnetism. And as a side benefit, you know, as a, as a, on the side, they also predict, you know, waves of radiation that travel at this universal speed. But Maxwell couldn't understand how that was possible without there being some medium, which we would later call the ether,
Starting point is 01:08:37 and then that would later be disproven. But he had this mechanistic idea, whether there were these vortices and gears and whirlpools. And so imagine you're back in 1860, too and you see this paper on Twitter you know and it's like oh well there are waves of light that travel at universal speed and they're carried upon gears and vortices and whirlpools and this guy's an idiot like he would say he's wrong even Matt so um so there's a danger you know and kind of uh being too too right and being too married to this explanation even from a philosophical point of view but anyway this has been great and uh not a great great time talking with you. My natural philosophers in the audience, very much enjoy it. And
Starting point is 01:09:24 I'm being called to go to another meeting. So I got to run. It's been a massive honor and a privilege. Thank you so much for talking to me. And hopefully we can speak again sometime. That would be great. Maybe I'll bring a meteorite to see you next time I'm visiting some stone piles in a mound outside of your, outside of Lernerner. I would love that. I'm just not going to set foot in Gloucester. I'm not going to. You can wear a druid robe. We'll definitely avoid Gloucester. Take care, Brian. All right, and Merry Christmas to you too.
Starting point is 01:09:53 And to you as well. Merry Christmas. Thank you so much, my friend. Bye-bye. Bye-bye.
