Starting point is 00:00:00 Next up on StarTalk, we've got a StarTalk special edition filmed live at Guild Hall. We have our geek and chief, Charles Liu, with us. We needed him for this one because we explore the role of the quantum and other exotic scientific elements that have appeared in the powers of superheroes. Coming right up. Welcome to StarTalk. Your place in the universe where science and pop culture collide. StarTalk begins right now.
Starting point is 00:00:40 Welcome. This is a live recording of this StarTalk podcast here in East Hampton in Guildhall. Thanks for coming out on a Sunday night. Tonight, you probably came and didn't know what the subject would be. Is that correct? So I feel the love, because you come no matter what. That's a good fact. The subject tonight is superhero science.
Starting point is 00:01:05 Ooh. And we got the expertise for that because we found it. But let me introduce the rest of our panel up here. First of all, Gary O'Reilly, Gary, come on out. Gary. Thank you. Gary. Former soccer pro.
Starting point is 00:01:25 There's a wiki page. on him, actually. You're going to go there again? Yeah, we got to, yeah, we got to, I got to say it every time. A former soccer pro in the UK, a soccer announcer, and he's with us for this branch of StarTalk that we call Special Edition, which focuses on how science and technology come together to enhance, augment, or adjust human performance. And when we speak of the science of superheroes, some of that might.
Starting point is 00:01:57 reach us one day in terms of what may lie in our future. So who else we have? We have Chuck Nice. Come on out, Chuck Nice. Yes. He's an actor, a professional comedian, and my long-term co-host for the series. I love him because he's scientifically literate and he's... And I'm cute. They'll be the judge of that. Okay. So we have an empty seat there because that's our special guest this evening. I don't know if you know this. Perhaps you attended this evening because you have a little bit of geek in you, but there's something you should know that no matter how geeky you think you are, there's someone geekier than you. Okay? So I carry strong street cred in the geekiverse, but our guest tonight is geekier than I am. Please welcome my friend and
Starting point is 00:02:55 colleague, Dr. Charles Lou. Charles, come on out. Charles, a professor of astrophysics at the College of Staten Island in the City University of New York. And he's also recently the author, check this out. Here's a title, oh my gosh,
Starting point is 00:03:12 the handy quantum physics answer book. Is that geeky enough for you? Because you know you have these burning quantum questions that must be answered. So, Charles, welcome to the show. Thank you. This is not your first rodeo with us. That's right.
Starting point is 00:03:30 But any time we want to reach out to the geekdom, or the geek universe, you are a prime person for that. I don't know what to say. All right. I hope not later on, because we need you to say stuff. So Gary, you conceived this show. So won't you set it up? Yeah, well, as you said, we always try to consider the human condition. And superhero movies aren't strictly sort of science fiction.
Starting point is 00:03:54 but they kind of are and they've been long part of our pop culture we've idolized them, we've scrutinized them and we've wondered and they've been riding the wave of quantum theory, that golden age of quantum theory and I think tonight we'll kind of explore the pillars of science fiction and superhero science.
Starting point is 00:04:18 Let's start off with a classic scenario. I've got to you, Charles, for this. It's the OG, Superman. Superman, right? Wow. The damsel, once again. But just to be clear, was not the first Super Bowl.
Starting point is 00:04:30 No, he was one of the OGs. No, no, I think you go back, I mean, we had Hercules. Oh, okay, we're going that far back. In terms of legendary storytelling, is Hercules any different to that world of... Hercules, Hercules. No, I mean, Superman is our version of Hercules. Every culture has their own superhero that they've thrown forward.
Starting point is 00:04:52 So, as I was saying, Superman's origin. is from comic books. Hercules was not in a comic book first. Oh, I thought he was in a comic book. Okay. It's chiseled into stone. Now we've got that settled. So, as I was saying, the damsel's being pushed off the balcony of the 32nd floor again.
Starting point is 00:05:09 She's hurtling. That's her. And so then he comes in. He swoops in and he grabs her. But from a physics perspective, Charles, what would really happen? Well, the problem is, of course, if Superman is a man of steel. And the thing is coming down, right? And you're coming up with the steel.
Starting point is 00:05:28 It's like hitting the concrete ground, right? So the poor damsel in distress would be quite rescued, but also quite squished. So quite dead. Basically, he kills her. Yeah. This is... She's a bug on a windshield. Well, the problem is, of course, that moment of impact, right?
Starting point is 00:05:46 And so it has been hypothesized that Superman actually has a way to absorb motion. In other words, the momentum and the energy, he actually not only can get there and stop the person from hitting the ground, but also can absorb the impact so that he himself, who is invulnerable, is unharmed, but the person who is falling is also unharmed is because it's as if they had fallen and just stopped in midair.
Starting point is 00:06:15 So it's like airbags. Like airbags. Okay, so quantum cosmic superman flying up. He wouldn't have to do that. He could just wait until they fall, but typically you see Superman flying horizontally. So that's quite a calculation to fly horizontally and perfectly intersect when the person is where you are.
Starting point is 00:06:31 Yes. Superman's brain has to be at least as good as your average computer. Right. Right. So Superman, everything about him is super. Yes. Right? And I wondered, we actually got a question, a branch of our podcast that goes online,
Starting point is 00:06:48 are questions open to the public, our fan base. And one of them just simply ask, would Superman's physiology be the same as humans, even if he's sort of steel on the outside? And it got me thinking, if he's got super everything, but he does eat food. We've seen him eat. Right. So the food would be digested in some super way, perhaps. Okay, so what would that mean? And then I thought, so everything that's going on in you would happen in a super way in Superman.
Starting point is 00:07:19 So it would digest faster. It goes into your intestines. And a lot of the action is in your lower intestines where the microbial action happens anaerobically. Uh-oh. Here we go. And anaerobic gases. Methane, sulfur compound. Yeah, super taco Tuesday.
Starting point is 00:07:44 Yeah, so hydrogen sulfide, that's the smell of rotten eggs. You have a methane, which I didn't know this when I was in camp when I was 10, but my fellow campers were right when they said, have you ever ignited? Yeah. That thing which must not be ignited. Come on. I know we're in the Hamptons, but everybody knows what a fart is. Come on.
Starting point is 00:08:09 Come on. No, but so, okay. So, you can ask, what is the gaseous composition of that? Okay. And in Superman, it would be super, right? And methane, of course, is highly flammable. Yes. And in cities, it's the gas of choice for your stove, if you still have a gas stove.
Starting point is 00:08:29 Suburbs tend to have propane. These are varieties of flammable gases that you get from crude oil. So methane is flammable. So it occurred to me that this is another tool Superman would have. in crime fighting because he would just sort of load it up, okay?
Starting point is 00:08:56 Then roll down his pants and just let one out and he's got the vision. Laser vision. Laser vision. Then he, but no, we can get to x-rays, yeah. All right. He's got, he got laser vision. He could just ignite it, and so it would be a new kind of flame thrower. Oh, what a terrible death for those
Starting point is 00:09:14 villains. No, no, that would be a, It's physiological. Yeah. It works. I think it would work. You could never sneak up on Superman with kryptonite. Why? Because there'd be a rear-guard defense.
Starting point is 00:09:29 Oh, yes. Yes. You couldn't get close to them. Couldn't take them from behind. Literally would be a fireball. Yes. Yes, a fireball. The only problem with this very reasonable reasoning
Starting point is 00:09:38 is that when Superman came to the world from Krypton, he did not have gut bacteria again. yet he was still like pre-colonoscopy okay so any gut bacteria he has achieved from eating here on earth has come from earth so this is a fascinating question which i would love for your opinions okay does superman have super gut bacteria or just ordinary gut bacteria in which case right if he has super digestion which you said earlier which would be great it might be so good as to eliminate all gaseous emission, in which case Superman never passes gas. Oh.
Starting point is 00:10:24 All right. So, Superman has X-ray vision. All right, yeah. Right? There's a scene in one of the movies where Lois Lane walks behind a lead planter because he asked, well, if you have X-ray vision in her first interview, then what color panties am I wearing? And he said, I don't know.
Starting point is 00:10:38 And he says, well, why? Oh, because you're standing behind a lead planter because everyone knows lead. Of those dors X-rays. And then she steps down and then he says pink or red or something. But X-rays should not be able to tell color of clothing. That's right. Ah. It's true.
Starting point is 00:10:57 It would just go through the clothing. That's right. Right. Right. Yeah. But you're not accepting poetic license, how are you? Not at all. None.
Starting point is 00:11:03 No. No. Right. Okay. If you're going to use X-rays, then stay in the X-ray world. Otherwise, invent N-rays or something. Invent some other rays that he had. If you're going to stay X-rays, you better stick with what we know.
Starting point is 00:11:13 So what you want is an upgrade for Superman, just X- X-ray vision and then a whole load of different dial-up vision that we could use. See? See, they didn't think of that. Well, if you think about... It's got a whole alphabet. That's right. Yeah.
Starting point is 00:11:26 Y-rays, Z-rays, yeah. We'll make a raise. Yes. Well, X-rays, as many of you know, they go right through our bodies, right? And they go through different materials and wind up with different colors. For example, our bones look different from our soft tissues and things like that. X-ray telescopes that we're familiar with, the Chandra X-ray observatory, X-M-M-Newton, things. like that, they can look at the x-rays, but x-rays are also different colors. Some of them
Starting point is 00:11:51 are what we call hard x-rays, some of them call soft x-rays. And in the same way that we can take pictures in red, green, and blue, and then mix them together to form a color photo, Superman could be able to detect or even emit x-rays and come back and forth in these different bands and thus create a three-color image. This is an undeveloped feature he could have expressed. That's right. This is an evolutionary superiority that he has. But instead of us having rod and cone cells, he has some sort of x-ray rod and cone cells that allows him. So we are limited to just the visible spectrum,
Starting point is 00:12:23 red, orange, yellow, green, blue, violet. Yes. He's got x-rays as a whole accessible part of the electromagnetic spectrum. That's right. And all he does is just see through walls with it. Yes. But it's way more useful. Highly underdeveloped.
Starting point is 00:12:35 He's modest, man. You know what I mean? He probably could do all that, but he just doesn't want to let you know unless you're asking him about Japan. Is that right? Hi, I'm Ernie Carducci from Columbus, Ohio. I'm here with my son Ernie because we listen to StarTalk every night and support StarTalk on Patreon. This is StarTalk with Neil deGrasse Tyson.
Starting point is 00:13:16 The thing about his gut, we know Superman came here as an infant. Yes. So I once got a phone call from DC Comics in my office. You're in trouble. I work at the Hayden Planetarium, in case anybody, was dragged here by the person next to you and doesn't know anything else about me. That's where I work. And, I don't know, 10, 15 years ago, I got a phone call. Hello, this is Dr. Eisen?
Starting point is 00:13:43 I said, yes. This is DC Comics. Can we ask you some questions? I said, sure. We have a new comic book we're illustrating, and we want to know if we can illustrate Superman visiting the Hayden Planetarium. Will you give permission for this? Yeah, I mean, who's going to say no to that, right?
Starting point is 00:14:01 So I said, what's up? And they said, oh, Superman, in this story that they're telling, is going to come to the planetarium to use our special tools of visualization and telescopes and things to. You see the destruction of Krypton, which is finally reaching Earth. And I said, oh, that's good. That's good. But I had to dig in.
Starting point is 00:14:30 And I said, all right, Superman was launched Moses style in a basket as an infant, arrived on Earth in that same basket as an infant. And anyone who knows infants knows that a month, two months, you know the difference between the baby who's two months old and was the three months old. This baby did not age. So there's only two ways. I'm telling this guy on the phone. Only two ways.
Starting point is 00:15:00 And he's taking notes, right? He didn't argue with anything I was telling him. I said the two ways it could have gotten here. If he traveled, because they're aliens so they could do what they want. If he traveled the speed of light to Earth, he would not age relative to Earth, because that's Einstein's relativity. However, if he's traveling the speed of light, so is the destruction of Krypton. That light, those light beams from the destruction would be right alongside him, and he'd land on Earth. You'd see Krypton destroyed.
Starting point is 00:15:33 He couldn't show up later and then observe the event. So it can't be the speed of light. It was at this point, the gentleman from D.C. Comics knew that he had made a mistake. So then I said, the only way you can get him here and have all his work is through a wormhole. Okay? A wormhole. If he put him through a wormhole, he gets here instantly long before the light beam. That's really, that's very cool, man. Okay, to be honest, that's really cool. Okay, so now, hang on.
Starting point is 00:16:09 So then I said, Yeah, hang on. How old is Superman? And he said, he's eternally in his late 20s. So I said, okay, I can find you a star that's like 26, 27 light years away, and I can make sure it's red
Starting point is 00:16:27 because there are plenty of red stars in the galaxy because the Krypton star is red. And we can make that the star he came from. I can find an actual star. He said, yeah. So I went to. Went back to my cattle. But is there an exoplanet around that star that could actually be Krypton?
Starting point is 00:16:43 Well, most stars will have exoplanets we knew at this time. So I wasn't worried about that. Okay. So I gave him a choice of two or three stars. Okay. Okay. And they said, we'll take this one. I said, why?
Starting point is 00:16:56 Oh, because it's in the constellation Corvus, one of the 88 constellations of the night sky. Corvus is a crow. And I said, well, why? They said, oh, the mascot of Smallville High is the crow. I said, oh, that's good. Whoa. So there it is. It's now Superman Canon, this conversation.
Starting point is 00:17:20 And so, yeah, they drew him. And then they called me back and said, do you mind if we have him meet you? And I said, yeah, let's do it. Okay. So in this comic, I am meeting Superman. And there's a tender moment because he sees the destruction of Krypton. And he's sad. He's crying super tears.
Starting point is 00:17:37 Yes, he's just sad. And I realized at that moment, I'd never seen Superman emotionally sad. Right. At angry, sure, but not just genuinely sad. Right. And so I know a little more than usual about how Superman got here because of that conversation. So here's the takeaway, people. Neil deGrasse Tyson made Superman cry.
Starting point is 00:18:00 Yeah, you did. Okay, so now they didn't show him opening up a wormhole. just sent him here. Right. And that was that, yeah. Okay, so you've touched on wormholes. Yes. Faster than light travel. Yes. And I think everybody in the room, me included, wants to know, what are we going to be traveling by in the future if we actually get to do that? Is it going to be a warp drive? Is it going to be a wormhole? Is it going to be a transporter? What is it going to be? You know, I was hanging out with William Shatner. As you do. Yeah. You know, who doesn't? And I told them and I said,
Starting point is 00:18:34 the day we have wormholes, you won't need transporters. Right. Because there's a pop a wormhole where you and the planet's surface and step through, and there you are. You don't need the lights and the sounds and the room and the Scotty on the switch. So this is an important choice here. So, Charles, can we make a wormhole? No.
Starting point is 00:18:55 Why not? Thank you. All right. There you have it. No, no. Bill Satter is going to be so disappointed. Actually, in the original Star Trek motion picture, the enterprise almost got sucked into a wormhole
Starting point is 00:19:07 because there was a warp drive malfunction and they were forced to be pulled out. You guys all remember that? Yeah. Now, the story is with wormholes is it requires a great deal of energy to have happen. A transporter supposedly, they could draw the energy
Starting point is 00:19:22 from some sort of mythical slash mystical warp drive engine or something. And so that was something that you could do person to person. A wormhole requires something much more supernatural, more powerful, a black hole, for example, or some sort of mystical creature, someone who could master magic and dimensional travel. So in that sense, the wormhole strategy is less likely to be our strategy than a warp drive type strategy, where we can somehow move faster than the speed of light through space, through our controlled engines. So do we borrow
Starting point is 00:19:58 this energy from another dimension? Ooh, good question. Yeah, because how much Because if this is like the galaxy, and you warp it, and then you travel through the little bridge and the warping, you un-warp, then you can cross the galaxy during the TV commercial, and then you can make it. Right. Yeah. The problem is, you have to, in that scenario, you are warping space. That's a lot harder than warping ourselves. You're warping the entire galaxy. Right, the whole galaxy.
Starting point is 00:20:24 That's what a wormhole would have to do. Yeah. You see. Okay, got it. So what happens is with warp drive, this is all sort of retroactively created after. after the television show, right, was so successful. The idea is that you put the enterprise or your spaceship of choice into a little bubble
Starting point is 00:20:40 that is outside the regular space time that we live in. But it's inside in a little pocket, right? So it's almost in its own extradimensional travel. And what happens is that bubble can move faster than the speed of light, even though you yourself cannot. So while you're in the bubble, that's when your warp drive is working.
Starting point is 00:21:01 It's not warping space. It's warping you into, out of, through, and otherwise bubbly, bollibley, bobble, in space. Which would take much less energy than folding the whole universe itself around you. In fact, a Mexican physicist named Miguel Acubiieri used Einstein's general theory of relativity and actually came up with some mathematical equations
Starting point is 00:21:24 that could make a warp bubble like that exist. So mathematically, you could do it. The problem is, Once you've made the bubble, how do you move that thing so fast? And we still don't have anywhere near the technology to be able to do that. Okay. What do you do with it once you've got it? You go through space time at faster than time.
Starting point is 00:21:44 Once you've made the bubble? Yeah, and you've traveled. Right. Then what happens to the bubble? What you have to do is literally warp the bubble in such a shape that the space behind it is changing at a faster rate than the space in front of it. And that's how you get it to move through space. You keep warping in this sort of continuous way
Starting point is 00:22:03 so that the warp pushes you forward through space. That's not what he asks. How do you get out of the bubble? Once you get it off. You pop it. There's my answer. Quite literally. Your dilithium crystals in Star Trek, right?
Starting point is 00:22:16 Your dilythium crystals are shut off and then the bubble just evaporates around you. Oh, okay. So I have this dream of the future where wormholes, because now you're putting a kibosh on it. Wormholes are how we get around, which means no one needs roads. Not only that, your back of your refrigerator could be connected via wormhole to your grocer. And they pop it open.
Starting point is 00:22:39 Oh, the milk is, and they put in fresh milk and eggs. And you just have a contract to have that loaded. And there's no truck. There's no, it would put Amazon out of business. Right. Or the trucks would, the drivers. If we could move wormholes, one end here, the other end there, and just move them around at will, then your scenario is completely likely.
Starting point is 00:23:00 The problem is it takes so much energy even to create a wormhole with two stable locations that even if it were physically possible, which we don't know yet, when that happens, it's station to station. Yeah, but if we told the Wright brothers, one day we're going to fly 400 people
Starting point is 00:23:15 at 600 miles an hour across the ocean, so that takes too much energy. Are you kidding? We're flying a bicycle right now. So that is, challenge. Where is your sense of time perspective in that declaration that you're making? I would say that sometime within our lifetimes, we will be able to generate something that we
Starting point is 00:23:40 have tried to do since the end of World War II, and that is controlled nuclear fusion. Whoa. We will, at the moment, there is some technology that's happening being developed all over the world, including in France at a site called... Charles, that's a low bar. I'm talking about the future. But wait a minute. I don't know if that's a low bar, because when you think about it,
Starting point is 00:23:57 What we're talking about here is the need for massive amounts of energy. So if we're able to control fusion, which, I mean, we know what kind of energy is packed in the back. I get it. I'm just saying we should have had fusion decades ago when we're not there yet. That's right. So I don't want that to be the – I want that to be a given and now give me, like, extra cool stuff. Okay. That's all right.
Starting point is 00:24:20 So now, but let me just shape the conversation a little differently. Okay. So we're talking about warping space, all right? There's another feature that we've seen in different films, and that's becoming invisible. Not disappearing, but just... No, that's a different thing. That's something different.
Starting point is 00:24:37 I know how you do that. Get older. And then try to talk to young people. Yes. Visibility playing a very prominent role in Fantastic Four of the most recent superhero movie. featuring the invisible girl, now invisible woman. And there was the invisibility cloak in Harry Potter.
Starting point is 00:25:03 You got Star Trek, the Romulan device. That's my vulgar device. Right, right. So, oh, also in the original Predator movie, he could go invisible. But in all those cases, there was a little bit of little jittery. A shimmering, shimmery thing. Like silhouette.
Starting point is 00:25:21 Yeah, exactly. A see-through shimmering silhouette. So I'll tell you what I know about this. Charles, you might know more that there is work on this. It is real. In fact, in that there's a James Bond, I forgot which one, is a quantum of solace? One of those where his Aston Martin has an invisibility button and he presses it and it just becomes invisible. But it shimmers into invisibility, of course.
Starting point is 00:25:43 You can still shoot it. You just can't see it. Okay? You don't know where to aim. And so there is research now because what does it mean to be invisible? It means light from behind you continues to your sight line as though you're not there. So what you do is instead of blocking the light, they have a series of reflectors that coherently moves the light around your body and then sends it forward as though it didn't take this detour.
Starting point is 00:26:20 And you're sitting on the other side of me. you just see the wall behind me and you don't even know that I'm there. There are demos of this online. They're YouTube videos. You can see this. Authentic, that's not AI fake. The problem is, now it works only
Starting point is 00:26:37 if you're exactly aligned with it. If you go offline, then the effect collapses. But that's a start. And you're functionally invisible when you can pull that off. Marvelous. Yeah. I was not aware of the technology.
Starting point is 00:26:51 But there's different types of invisibility. Yeah. If you look at a stealth bomber, for instance, right? It's invisible on the right, but that's only in that particular area. Very important. In fact, so the stealth bomber has a radar cross-section of a bumblebee. Okay? It's a dangerous bumblebee right there.
Starting point is 00:27:11 Yeah. Imagine that radar, like... A hell of a sting. So if you are trying to detect planes with radar, so just at the risk of stating, the obvious, the radar hits your intended object and it reflects back to you in the shape of what the thing is. And you can look at the blip and if it's got any kind of detail and you put some AI on it, it'll tell you what the plane is.
Starting point is 00:27:38 The stealth bomber is designed very specially so that any incident radar reflects in a different direction than straight back. Wow. Okay? And can we get a version for this for speed traps? Because to try to send it, then it doesn't go back. Doesn't go back. You'll whizz by and it'll just say there's nothing
Starting point is 00:28:06 there. Exactly. Right. So if you look at how the surfaces of the stealth bomber and other stealth technologies are shaped, take a line and hit it and it'll never send you back in the direction you came on any surface. Okay. So it's all faceted and... Correct. Yeah. Correct. And just a side fact,
Starting point is 00:28:26 the earliest of the stealth bombers, I think it was the F-117 used now decades ago, had flat surfaces on it. Okay? Take a look at fascinating history of this. You know why it had flat surfaces? Because the computers were not powerful enough to perfectly solve the equation to have a continuously curving surface. So it had to approximate it with flat surfaces so that still reduced the radar cross-section, but it didn't take it to as low as the bumblebee. Once we could fit it with high-performance computing, you can curve the surfaces so that hardly any signal goes back. So here's the problem. Exactly your point. Its radar cross-section is a bumblebee. But if you just step out and look up, there it is. Okay. Its optical cross-section is the full plane.
Starting point is 00:29:19 Okay. So where you are in the electromagnetic spectrum matters here. Totally. Well, invisibility isn't all that great of a superpower by itself. Let's face it. If you can just hide, that's great. But you've got to do something other than hide, right? And so, in fact, with the superheroine, the invisible woman, the Marvel Comics back in the 60s, developed an extra power for her.
Starting point is 00:29:46 Not only did she have the ability to turn invisible, She also could project invisible force fields. She could actually do things invisibly to you without even touching you. All she had to do is to envision a shape of something made of force that was invisible and then be able to lift you up as if you were sitting in a chair or to move you around or to push you back. It had the ability to protect and be invisible at the same time. So that's effective even if the force is not invisible. That's right.
Starting point is 00:30:18 Right. It's a field around you. Right. And do that. Now, we know in quantum physics, there's an effect. Quantum is spooky, weird stuff. That's why everyone, it attracts people because they want to understand it. And quantum physics is not there to understand. Charles, crack me from a way.
Starting point is 00:30:39 No one comes out of a quantum physics class. Oh, I understand that. No, you don't. Okay? It is just what the you. universe does on the small scales, we can describe it, we can calculate, but we scratch our heads every single time. And one of the effects, fascinatingly, is if you take two very smooth, very flat metal plates and evacuate the space between them, so it's a vacuum, you start making them
Starting point is 00:31:09 closer and closer to each other, there is a point where there's a whole new force that pulls them together. It's not electromagnetic. It's not gravitational. It's not the strong nuclear force. It's some new thing. Maybe they just really like each other. Good point. They pull each other together. And that discovery won a Nobel Prize. And so the Kazimir effect. Yes. The Kazimir effect. Yes. The Kazimir Force. So what is, tell us, what causes that? The Casimir effect is caused because there are things called quantum fluctuations in our universe. Even when things have apparently no energy or no change at all, at the quantum level levels far smaller than atoms with energies far tinier than a single, say, electrical pulse, there is a little bit of this happening all the time all around you. So if you are getting a smaller and smaller space between these two plates, you get to a small enough point where the quantum fluctuations are actually bouncing off of those plates.
Starting point is 00:32:20 And so you create an attractive or sometimes a repulsive force that kicks in only just before they touch because the quantum effects, small as they are, are definitely there. And so you can imagine actually influencing something without actually pushing on it or pulling on it. It's actually just the quantum work that's being done because the universe is shimmering on that tiny level. You have to get really, really close. Super close. So I'm a villain, just your average villain, but I want to upgrade to supervillain. How am I using the Kazimir effect? The Kazimir effect.
Starting point is 00:32:54 Is it like your hair kind of good stuff? Yes, that's a great point. If you somehow were a superhero or a supervillain that could take advantage of quantum fluctuations, You might be able to say, I hereby declared that the quantum fluctuations in this part of the universe are going to be reduced. In exchange, the puns in this part are going to be increased. All of a sudden, you have all this extra energy over here and much less over there. So you could imagine something literally being sucked from here to there due to quantum effects alone. Because the object naturally wants to go from high energy to low energy.
Starting point is 00:33:31 That's right. So you could move something without doing anything other than just changing the quantum. quantum fluctuation. So you're creating a gradient. You're creating that gradient. And the problem, of course, is that this is a much larger space than the quantum fluctuation spaces. Anytime you have a quantum fluctuation, we're talking things that are billions of billions of inches, going from this part of the room to that part of the room. If you wanted to carry me from here to there, that's many, many, many, many, billions of inches. So by the time that happens, I think we're all going home. Yeah, so there's a... Not yet, not yet. There's a physicist. There's a
Starting point is 00:34:06 George Gammon. He's a hero of mine because he was an active physicist, and he wrote for the public. And he was one of the first people who hypothesized the hot Big Bang theory. Yeah, that's right. That's right. And so he had a series of books called Mr. Tompkins in Wonderland. And each book, it's fanciful, and he illustrated it with cartoon illustrations. Each book was you living in a world where the universal constants have different values. So, for example, instead of the speed of light being as fast as it is, speed of light is 60 miles an hour. Oh, wow. So you drive down the street.
Starting point is 00:34:45 He's describing this. And as you go to 30 miles an hour and 40, he's describing how all your scenery changes. And so it was such a world to jump into, which has me wonder if you had real power over the universe and you could adjust the value of the physical constants that control quantum physics. Maybe you could dial that up so that we respond to quantum physics in the way particles do. Yes. There is an episode of Star Trek The Next Generation called Q Who, where this exactly happened. Really?
Starting point is 00:35:20 Yes. The great creature named Q, who was being punished by his other fellow Q's had been powers rule. As one would happen. Yes, right, because he was being too mischievous. So what happened was that they were having a problem on a planet and trying to solve that problem, And they couldn't figure it out. And so they asked Q, said, what would you do?
Starting point is 00:35:38 He's like, oh, it's obvious. Change the gravitational constant of the universe. And all the rest of the humans are like, we can't do that. But the engineer, Jordi LaForge, said, hey, maybe we could. Right. That's the superhero you're talking about. Somebody who could actually change the gravitational constant of the universe, and boom, suddenly your planet is as light as a feather.
Starting point is 00:35:58 Just because you change the force of gravity. Just because you change force to that in that. That's a bad-ass power right there. You're thinking like a supervillain now. No, I'm, stop. Don't bring me into your category. So what intrigues me about, I think most about what has happened in this world is there are some writers who know that matter is mostly empty space. Ooh.
Starting point is 00:36:24 We think we're solid, objects, and we're just not. And you can say, how empty are we? Well, let me first, let's go back to Ernst Rutherford, who's a New Zealand physicist, a turn of the previous century, around there, I think, or a little later. 1900, 1900. Yeah, around there. And he did experiments where he hammered gold very thin. Gold is very malleable, so it's the most malleable substance on the periodic table.
Starting point is 00:36:58 So you can hammer it, that's why gold makes very good leaf. Leaf, gold leaves. Yeah. On cakes. What is this a word for it? Gilding. Yeah. Oh, I wonder how that happened.
Starting point is 00:37:08 Guild Hall? Gilding? Yeah, okay. So anyhow, if you gild a statue, you take gold leaf. And using very little gold, you can greatly shine something up. And that's why the Oval Office looks that time. Goat leaf everywhere. Absolutely beautiful.
Starting point is 00:37:28 No. Don't encourage him. Yeah, don't encourage that. Okay, so he hammered it really, really, really, really thin. Okay? So the whole leaf is just dangling there. And he fired particles into it. 99.999% of the particles went through as though nothing was there.
Starting point is 00:37:54 Oh. And occasionally one would bounce back the other way. And when he did the math on this, he realized that atoms are mostly empty space. And it is rumored that the next day, he alone on earth knew this, that he was afraid to step onto the floor from his bed out of fear he would fall through. Just like the nightmares of a classical physicist transitioning into the world. of the quantum. Believe me, I have been that high in my...
Starting point is 00:38:31 So, if you want a physical example, the nucleus of an atom is to the size of an atom as a crackerjack kernel of corn is to the entire stadium. In which you may purchase it. Are you sure we got the right analogy here? You said one cracker jack to the size of a stadium is the nucleus of an atom to the atom itself, the structure of an atom itself. Yes. I'll give you another analogy, Chuck. Please do. If we took all of the Hamptons, took the space out of it, all of the Hamptons, including us, would fit in my fingernail. Man, you just messed up a lot of real estate value.
Starting point is 00:39:26 No, but it's true. The universe is 99.999999-999-99-99-99-99-9-99-9-9-9-9% empty space. And that's just the Adam's... Why don't we... Here we're a double-edged question. Okay. Firstly, why don't we just keep falling through stuff or putting our hands through things? And...
Starting point is 00:39:45 Exactly. Yeah, exactly. Is this the theory of probability? So, having asked that question, I know the answer to it. So how is a superhero using this to their advantage to walk through a wall? We've got the flash, can run through walls, and... But the flash can run through walls? I thought he just ran fast.
Starting point is 00:40:09 Through walls? He can vibrate. He can vibrate. And you have Dr. Man? He can just move through things. Wait, wait. Right. So the flash can do what?
Starting point is 00:40:18 He can... He's like, hey... And that didn't get him through a wall? And he can get through a wall by like, shimmying, vibrating... Wait, wait, Charles, is he moving? through the empty space of the atoms as he goes through? He's quantum tunneling, yeah. Quantum.
Starting point is 00:40:30 Okay, we better talk about that. Quantum tunneling, here we go. Yeah, okay, here's a story. Don't leave me hanging. See, because you have this 99.99999% emptiness, the reason we don't keep falling through the floor is because those itty-bitty bits of material actually produce force fields. Uh-huh.
Starting point is 00:40:49 So there are fields of force, mostly electromagnetic, some nuclear, some gravitational, around the particles that make us up. So, for example, when I'm clapping my hands together, it is the force fields of the atoms in my fingers that are touching each other. And that is what's creating the sensation in my hands. And that's why your hands don't pass through. That's right, because they just tap each other
Starting point is 00:41:12 because the fields are there. But it was shown 100 years ago that every once in a while, because there's all this empty space and there are fields involved that make this all not fall through, that every once in a while, something will go through just by accident
Starting point is 00:41:27 because the shimmering quantum fluctuations every once in a while will shimmer just right so that a little particle will actually go right through. That's called quantum tunneling. And this can happen, and in fact happens all the time, and I was so surprised to find out when I was writing the handy quantum physics and answer book that it was part of electronics technology for decades.
Starting point is 00:41:47 There's a thing called a quantum tunnel diode that was in many radios and other transesting products that were for sale in the 50s, back in the day, 1960s, 1970s. They are now obsolete. This is quantum technology that's now older than our non-quantum technology
Starting point is 00:42:04 that's in our cell phones, for example. But quantum tunneling is a real phenomenon and it happens all the time. But the flash is supposedly so good at this that he can vibrate his entire body all of his trillions and trillions of molecules and go right through
Starting point is 00:42:21 and figure out exactly the jigsaw puzzle way to get through the other side. Oh, it's like that game show where the wall comes at and you have... Yeah, uh-huh. It's exactly that. But he's able to do it with every single atom in his body and every single atom in the wall. He doesn't leave the body hole through the wall. So is this basic probability that is a continual working out of which molecule is going to pass
Starting point is 00:42:43 as opposed to which... That's right. The odds of any single molecule doing something like a quantum tunnel is tiny. Now you add it up and multiply it by every single. single probability of every single other quantum tunneling possibility, and you have a number that's so beyond anything that even our current supercomputers can't even computer for one tiny later. But the flash can do it. But the flash can do it all. So is this the same thing as quantum teleportation? Yes. Oh, a little bit different. Oh, a little bit different. Okay.
Starting point is 00:43:11 Oh, do tell. Quantum teleportation is not be me up, Scotty. Okay, the term quantum teleportation actually predates the idea of teleporting, say, a human from one place to another using some sort of machine. But it was the idea of communicating information from one place to another. So copying a message perfectly, and then sending that message perfectly to a different location without any kind of degradation would be what we used to call teleportation. I didn't know that. So you're saying material objects were not part of that original? That's right. It was an information. thing. So Morse code, for example, was actually a way of teleportation because your dots and dashes here could be translated exactly as dots and dashes there.
Starting point is 00:43:58 With low error. With very low error. Oh. Quantum teleportation now is a little bit different. You want to move quantum information from one spot to the next. And then when you do that transportation, there is always a massive amount of noise and energy lost and your information gets lost. But if you can quantum teleport, and you can get this information from one spot to another without losing, you literally have an unbreakable code, a way to transmit information that nobody else in the universe can actually ever intercept. And that's what quantum teleportation is really cool about. And that's as great as value going forward. At this moment, that's right.
Starting point is 00:44:39 It would be a perfectly secure internet, for example. Yes, that's right. So what's our energy source for this? The energy source is merely the fluctuations that are caused by the quantum system itself. You're sending bits of quantum information, we call them qubits, and then you package them in whatever physical system you want,
Starting point is 00:45:01 whether it's an ion or an electron or some other set of particles, and then you send them either in a beam or along a wire or a fiber or something like that to another spot, and you want to preserve the coherence of information inside that qubit for as far as possible. All right. And it's got me. Is that happening tomorrow?
Starting point is 00:45:23 Right now, people are actually able to quantum teleport little bits of information for actually many miles. So you can do pretty well, like send just a few pieces of yes, no, up, down, so forth, without losing coherence. But the moment you have too much noise, the moment the temperature goes up above a few degrees, above absolute zero, you start losing information. Because things vibrate and they create a thermal. Those quantum fluctuations just overwhelm whatever you find out.
Starting point is 00:45:51 It's not good for texting. Depends on what you're texting. Guinea pigs. You mentioned absolute zero. Yes. That comes up quite a lot in quantum, doesn't it? That is true. It does.
Starting point is 00:46:03 Do things actually have to take place at absolute zero? If it is, then we might just be out of the equation. Yeah. Absolute zero is 459.1. 16 degrees below zero Fahrenheit. Ouch. Give or take. At that temperature, no motion of atoms or molecules happens above the quantum fluctuation.
Starting point is 00:46:27 That means that the reason we are warm is because the different atoms and molecules in our body actually vibrate and move and rotate and things like that. When all of that stops, that's the temperature known as absolute zero. Well, can you blame them? No. I mean, it's pretty doggone cold. It is pretty doggone cold. And at that temperature, see, what's interesting is it has been shown physically that we can never make a machine that reaches that temperature.
Starting point is 00:46:52 It is only a theoretical minimum because you cannot create any kind of refrigerator that can get a temperature of absolute zero in a space. So what is the coldest spot in the darkness of space? What would that temperature be? Ah, the coldest temperature we've been able to achieve is actually colder here in a laboratory than out of space. in space. Here in a laboratory, we've been able to get down to a few millions of a degree above absolute zero. But out in space... Oh, what a failure. Right, right. But out in space, we have the leftover heat from the Big Bang. It's called the Cosmic Microwave Background Radiation. Can't escape that. It's everywhere. And that's about three degrees above absolutely.
Starting point is 00:47:37 It's still damn cold. Yeah. Yeah. Yes. You don't want to go out there. Wear a jacket. Oh, cool. But it is very cool. So the big back. So the big itself is hanging around in such a way that it's warming space to the point what we can't get to an absolute zero. That's absolutely right. And that heat is actually very important in the universe because we have these cold clouds of hydrogen gas floating around in the universe. These clouds would be doing absolutely nothing and having no emission of energy or signal
Starting point is 00:48:06 of any kind except the cosmic microwave background warms them up just enough that once every 10 to 20 million years on average, a hydrogen atom floating around in space will do a spin flip and release one single photon of radio wave emission at a wavelength of 21 centimeters. And so that... And that means...
Starting point is 00:48:32 It's like, look, the two of them is just like, one photo. And it releases at... And Neil is just like, 21 centimeters What the hell are you talking about? It's the best inside joke in the universe. Okay.
Starting point is 00:48:51 See, we tried hard not to laugh during that time. But as Neil can explain better than I can, because this was actually part of the area of research he was doing more than I was, 21 centimeter radiation is what tells us where the hydrogen material is in the universe and how it's moving to make new stars, new planets, and new galaxies.
Starting point is 00:49:13 in the universe. So the excitation of these clouds. That's the right word, too. Yeah. What? That alone, is it now a chain reaction? Yes. Okay. You create that bath of 3D degree Kelvin cosmic microwave background photons, which in a turn causes these gas clouds to do something. And that allows us as astronomers to figure out how the universe is aging and what its processes are going on, billions of light years away. But just to put this to bed, if absolute zero is the coldest possible temperature, then you need something to draw the heat away from what's there. And as you do that, it's still kind of in contact with what's doing the drawing of the heat.
Starting point is 00:50:05 So in principle, it may be physically impossible to reach absolute zero. Because it's always, like you said, it will always be in contact with something that's not absolute zero. Gotcha. Because otherwise, everything is absolute zero, and it's not. Right.
Starting point is 00:50:21 Okay, there's some enclosure. So no matter how good your Yeti is, okay? Your Stanley Cup. All right, no matter how good it is, the ice in there eventually melts. Right. Okay, because there's heat transfer, however slow, it's not a perfectly, if it were perfectly insulated,
Starting point is 00:50:45 it would never melt. That's right. But that's not how the actual world works. That's right. So even without quantum effect, you will wind up with thermodynamic losses. But even at Absolute Zero, we're now pretty sure
Starting point is 00:50:57 that there are quantum fluctuations. The quantum. Yes. But so what about the superheroes that can breathe fire or something? Or whatever, they make fire. They're cool dragons. You mean like Godzilla or something?
Starting point is 00:51:10 Well, I don't know. any of any of the ones that or when superman burps oh we're back there with it yeah sorry everybody i'm just wanting thermodynamically yes the fire has energy so that energy has to come from within torch fantastic ford yes the human torch and the fantastic force supposedly is able to convert chemically like fire is basically a chemical reaction right uh something like a nuclear detonation or say the interior of the sun, that's a nuclear event. And so somehow that energy gets converted to heat depending on what the processes are in the sun
Starting point is 00:51:47 or in the person or in the campfire. Okay, so the fire superheroes don't need quantum effects. They don't. That's a simple burning. Yeah. Okay. Even thermodynamics is extremely powerful. A lot of us don't understand just how powerful.
Starting point is 00:52:02 But you know how there was this industrial evolution based on the steam engine, right? Yeah. Yeah. Just the heat energy in this room, right now. And it is hot. You people are hot, I'm telling you.
Starting point is 00:52:13 If you were to convert that into mechanical energy, you could take an 18-wheeler and drive it right through the wall from that side to that side and all the way out. You have so much kinetic energy from the thermal motions in the air alone that it's easy to see how you can have tremendous superpower, even if you don't have quantum power. So coming out of the industrial revolution? That's right. Yeah. Let's keep this going, just the fact that we know if the fact that we know if most of matter is, yes, most of the universe is empty space, and most of matter is empty space on top of that.
Starting point is 00:53:05 If you had the power to collapse particles down and then restore them, okay, you get a smaller version of yourself, and then a bigger version of yourself. That's Ant Man. Exactly. Ant Man. Yes. By the way, worst name for a superhero. It is. It is.
Starting point is 00:53:26 It is. Really bad. Well, but he's a pretty powerful guy. But that's the quantum mechanics. That's exactly the quantum mechanics. The mystical pin particle, right? Yes, that's right. They are borrowed from another dimension.
Starting point is 00:53:38 So are we looking at quantum mechanics being able to enlighten us and our understanding of higher dimension? What a great question. Thank you. It won't happen again. Don't worry. The so-called PIM particles is a fictional thing invented by Marvel Comics. There's a scientist named Henry P-Y-M. And by using these, harnessing these particles, which are sort of super-dimensional, you're able to,
Starting point is 00:54:05 make things big and small. You're literally in a sense taking something like this, making it small and then making it big or making it huge because you're taking advantage of the space in between your molecules and your atoms that we were just talking about. So this fictional particle is exploiting
Starting point is 00:54:21 known physics. That's right. Okay. Yeah, but this fiction... But let me ask you because what you just said, if you keep the same mass and you make me super big, I'm the stay puff marshmallow man. That's right. I'm a beach ball. Yeah, I'm a beach far, leg. And so therein lies the extra-dimensional part to which you refer. The only way that these
Starting point is 00:54:40 particles can work in our world, you know, as if they were actually in our world, right? But if they were really working, you would have to add mass to things as you were growing them. And you would have to reduce the mass of the things that you were shrinking, right? Otherwise, if you shrunk down your vehicle and put it in your pocket so that you could ride it later, you would not be running very fast. It would still weigh thousands of pounds. That's right. In your pocket. That's because it fits in your pocket. It doesn't mean it belongs in your pocket. That's right.
Starting point is 00:55:08 Okay. So somehow these PIM particles. It's kind of deep, actually, when I think about it. Just because it, oh, wow. That covers so many problems in life. It doesn't mean it belongs there. Yeah, I love it. Yeah.
Starting point is 00:55:22 So this material, this matter, had to either go into some dimension that doesn't weigh anything in our space time or be drawn from somewhere that previous. didn't have any weight in our space time and suddenly becomes having weight. So you're really shunting these things in and out of space time. Otherwise, your challenge would be the creation and destruction of mass in our own space time. That's right. And we know what happens when that happened. Those are nuclear bombs.
Starting point is 00:55:55 Right. If you take mass and make it energy, that's the end of your situation. I'm sorry, I don't know why I got all excited just then. Yeah, that's okay. It worries me, Chuck. No, no, no. Because nuclear fusion also powers the sun. Yeah.
Starting point is 00:56:08 It's a very benign thing. We often think about on our world as being dangerous, but in fact, without it, we wouldn't be here. Okay. We talked about quantum tunneling. Yes. There's another term that comes up. And if I think of a superhero, I go back to Dr. Manhattan. And that's the superposition where I am simultaneously in different parts, in any part of wherever I want to be.
Starting point is 00:56:33 And Dr. Manhattan could be in many places at the same time. He would be on Mars and on the moon and in his laboratory and, you know, all at once. Wait, wait, is that correct that way? Well, how many of you guys know Dr. He had access? Well, yeah, first of you. I know, we're geeking out here. This is turned into four guys at a bar.
Starting point is 00:56:55 But does everybody know who Dr. Manhattan is? Watchman. Yeah. Dr. Manhattan was created in the Watchman universe by Alan Moore in the 1980s. And this is a superhero which didn't really want to be a superhero. But he's essentially blue, and he's played by Billy Crutup, and he doesn't wear any clothes. And he just sits around in his blue. Is that your most obvious fact about him?
Starting point is 00:57:17 Yes. The man is the most powerful entity ever created, and he's going to say he doesn't wear clothes. I got to tell you, it looks pretty good naked. Anyway, the idea is that he is, by himself, a kind of quantum particle. he has the powers of doing anything that quantum particles can do but he is the size of a house and therefore he has an unbelievably
Starting point is 00:57:42 large amount of power because he can do all the things that can happen on microscopic scales but out on the scale of us and our sizes. So for him, his personal quantum constants are just larger. That's right.
Starting point is 00:57:55 It's as if George Gamoff himself. As we were talking about earlier, he's Mr. Tompkins in Wonderland. That's right. He is the Wonderland. That's right. Right. So I don't think it's that he was simultaneously in those places. He's just like a particle has a probability it can be found in any one of the places in its, what should we call this?
Starting point is 00:58:14 The wave function? The wave function? Anywhere it's wave function. He can say, my wave function includes Mars are going to be on Mars right now. So then he's on Mars. Right. Yeah. And he was. He doesn't actually have to travel there. He doesn't travel there. He's already there all the time. All the time. Right. Because he's entangled with himself.
Starting point is 00:58:29 Yes. But is it entanglement or is it many people? Great question. Let me try to break that down a little bit. Okay. You guys might have heard of quantum entanglement lately. It's in the news. It's very exciting and so forth. But actually, it's not in the Hampton's news. No? It's summer. Okay. I heard some people on the beach the other day talking about it. Quantum entanglement is the idea where you can take a particle and literally split it into two identical particles. and they can be as far apart or as old or as new or as kept or as they want and they will still stay the same particle. And know about each other.
Starting point is 00:59:12 That's right. So you have something that could be the size of a solar system and yet if you got information on one particle, you would instantaneously get the information on the other particle as if they were entangled. When in fact, in the quantum way of thinking about it, they are still one particle. One particle.
Starting point is 00:59:33 They just still happen to be connected as both a particle and a wave that keeps changing size and shape. So you have this particle, and we in the classical world think of particles as like a piece of stone or a rock or a piece of metal or something, just a particle, right?
Starting point is 00:59:51 But in fact, if you think quantumly, the particle and the wave are interconnected. And so the concept of size and the concepts of age are very, very different. And as long as you can keep that coherence and make sure that there isn't noise or static that interrupts the connection
Starting point is 01:00:09 between these pieces, they are one particle, no matter how far. There's a contest who can create the most distant particle pairs in this exercise. And the leaders in this in the world is China. China has the farthest separated particles.
Starting point is 01:00:26 Yes. Not for long. I'm here to say that I'm going to take care of this two weeks, two weeks, and China will lose. So it's a contest, we don't know, it's like, it's like an arms race, but we don't know why we, what good is it? Right. At this moment, physicists are still trying to figure out whether entanglement is a perfectly normal thing that happens all the time, we just never noticed it.
Starting point is 01:00:58 Or whether it's actually something profound that can be used in a way, for example, for instantaneous communications or other kinds of storage of information and so on. What we do know is that if you entangle some things, you can create this thing called a qubit, which is a piece of information that's not just one or zero that we use in our current computers. Which they call bits. That's right. They're called bits. But these qubits can take positions between zero and one, doing strange things in between until, something. until such time as you read them out as a zero or a one. Okay, this is a very odd concept in our heads.
Starting point is 01:01:34 But what it is, it means that we as particles or conglomerations of particles could in fact communicate or otherwise interact as waveforms of energy in ways that we can't imagine now but might be able, for example, to break computer codes instantaneously or allow us to do kinds of computations or communications. The future of...
Starting point is 01:01:57 We're on the doorstep of this. The doorstep of it. We're way, way, way, well, the door's very thick. Okay. But we are at the doorstep, yes. So what you're describing is that, I guess, in the lingo, the collapse of the wave function because the particles are waves, the waves are particles. But when it's manifesting as a wave, the wave occupies all the space that you're describing.
Starting point is 01:02:21 When we think of particles, it's here or there. The wave is, whatever you calculate the extent of the wave to be, the point particle can manifest at any point within that volume. And so then you collapse the wave function. There it is. Then there's the particle over here. So Dr. Manhattan would collapse his own wave function and he'd show up on mark.
Starting point is 01:02:41 Elapse it again and he's back here. Right. That's wild. That's the manipulation. Yeah. Yep. There you'll. If we've gone through the collapse of a wave function and we understand that there's
Starting point is 01:02:52 a duality of particles and waves, where does it go when there's a many worlds theory, because you're not quite, are you certain about that one? The many worlds, I'm... What is the many worlds theory? Ask Charles. Charles, please. Is it because you don't know? Enlighten us.
Starting point is 01:03:09 No, no, no. Neil knows he just doesn't like it as much. We've had this conversation a little bit before, but maybe we can expound on it later. See, here's the deal. About half a century ago, some physicists noticed that the mathematical equations that describe wave functions and quantum physics and so forth, don't necessarily have to reflect our universe alone. In fact, those equations are consistent with the picture
Starting point is 01:03:36 that every time a quantum particle does something or doesn't do something, a whole new universe is spawned. Who? Okay? Imagine if, for example, I go out there and I get hit by the jitney. Mm-hmm.
Starting point is 01:03:50 Okay. All right. That would be bad. By the way, I have a good lawyer for that. Thank you. Okay. As we determine. In most cases, I would not be in good shape.
Starting point is 01:03:58 But you could imagine a scenario in the universe where I'm hit by the Jitney and I'm fine. Just that one tiny possibility. If that happens, then that universe has me in it just fine. And then all the other universes, they continue to coexist, but I'm not fine. Now imagine tomorrow I get hit again by the Jitney. And then that process happens all over again.
Starting point is 01:04:24 There's a tiny little possibility that I'm fine. And that person survives. If I keep following the surviving me in front of the Jitney, I am in a universe where I live forever. Oh. Yeah, but you keep getting hit by the damn bust. Yeah. Right.
Starting point is 01:04:43 That sounds like hell. That ain't so good. I agree. But you see, the vast majority of other universes that exist in this mathematical many worlds I'm not fine. And that's the one that we are most likely going to share, right? Because the chances of me being fine after being hit by the Jitney a few thousand times. Very, very, very small. Right. But you can see the problem with this many worlds hypothesis of quantum physics, right? You're generating essentially a nearly infinite number of new universes every single second that the universe is around. It's not quite infinite because the universe isn't infinitely old. But in every single single, circumstance, you can imagine literally anything happening. Charles, isn't this kind of a cop-out? What is saying is we have the wave function.
Starting point is 01:05:33 Yes. And the wave can collapse here or there. And we don't know until you poke it or until it does collapse, but it might have collapsed over there. In fact, maybe it did collapse over there. And you're telling me, it did collapse over there, and that's a whole new universe. So what you're saying, you're taking our statistical ignorance
Starting point is 01:05:52 and trying to step out the back door by making multiple universes so that we're no longer statistically powerless. And why should I embrace that? You shouldn't. You don't have to. This is actually one of the... That's one of the universes, by the way.
Starting point is 01:06:08 That's right. In one universe... In another universe, you're just like, I love many worlds. Chuck is exactly right. You can literally imagine any kind of universe, and it has just... as good a chance of existing, assuming the laws of physics are the same in that universe
Starting point is 01:06:26 as in your universe, as your universe. Our universe, the one that we share right now in this room, is a collective collapse of the wave function, where all of our wave functions that make up who we are and where we are have all collapsed to this moment in this place. That makes our universe right now unique. If we allow the existence all those other universes, what does that make this universe, right? Mathematically, those universes are just as valid as this one, but we're in this one. Doesn't this
Starting point is 01:06:59 one have some greater validity than those? So, Charles, you're dead in this unit we've established. You've been hit by the bunch. Yeah, you're under the bus, buddy. So, then what about the Marvel universe where they keep going
Starting point is 01:07:15 in and out of the multiverse? Oh, yes, the quantum realm. Yeah. Is this some of that? Yes. Was that some of this? Here's the point. If you get that small, right, your wave function becomes pretty much melded with all the other wave functions
Starting point is 01:07:30 in this many world's universe. Right. As a result, if you figured out some way to navigate this quantum realm, which is far smaller than even what the Big Bang was just before it began to bang,
Starting point is 01:07:43 this is a millionth of a billionth of a trillionth of an inch, you know, really, really, really tiny. This Marvel Universe fake quantum realm thing suggests that if you just all you need to just be able to navigate this really weird quantum
Starting point is 01:07:59 tiny space and you can emerge in that universe where I am living forever despite being hit day after day, right? Then you can come get me from that universe and say here's the guy who can't be killed by the jitney, bring him back navigating through the realm
Starting point is 01:08:15 to here and then bring me over there and then you can engage in the most amazing insurance fraud in history. That's the quantum realm of Marvel Comics. Okay. Wow. Should we believe it? I wonder just what's
Starting point is 01:08:33 possible, right? And we're not quantum-sized. We can't play in Mr. Tompkins Wonderland. It's fun to think about, though. But you said the math works. The actual math works. Yeah. So the curious fact is mathematics as expressed by the
Starting point is 01:08:51 physicist, is a representation of our models of how the universe works using symbols, which allow us to manipulate the ideas perfectly logically, right? You can argue what's true or not, but once you've set it up mathematically, then manipulate the math. And that's tantamount to manipulating your understanding of the universe if it's the correct model of mathematics. So everything else about this math is working in our, you know, universe. Right. So I step lightly towards these other realities that are so mind-blowing.
Starting point is 01:09:27 Right. But again, is it more mind-blowing than what quantum physics might have looked like to the original classical physicists? And but we live, there is no IT revolution without the exploitation of the quantum. There is no creation, storage, and retrieval of digital information without quantum physics. It's not some other thing that other smart people worry about in the lab. It is with us.
Starting point is 01:09:57 We are embedded in it. There is no modern industry without it. Yeah. So... And if you were to go back to like 1910 and show somebody and an iPhone, you know, they'd burn you at the stake.
Starting point is 01:10:12 Yeah, they resurrect the witch burning ball. Yes, they would. Yeah, they were wrong about witches, and you know. So are we gradually inching towards the practical of quantum theory, rather than it being able to be achieved with immediacy. So I'm going to say it, and then I want to get Chuck's reaction. There's those parts of quantum physics that we need, that we want, that help us
Starting point is 01:10:35 in our technologies, in our computers, and everything. Then there's the part of the quantum physics that's just kind of floating out there that we have to take seriously because it's the extensions of what we know works mathematically and conceptually. So now you go to the edge and you explore the edges of those equations. Oh my gosh, you just gave me a whole new freaking universe. And what does that mean? And what is that going to take us? And I got entanglement. And I got all of this. That's why people are taking it seriously. Because the rest of it works. In fact, quantum physics is the most successful theory of physics ever put forth. It has never been shown to be wrong. And that's
Starting point is 01:11:16 spooky. Well, that's because nobody understands it. All right, let me try to land this plane here. Is what you're telling me that this sort of probabilistic understanding of a particle, the wave particle duality, when it's manifesting as a wave, we don't know where the particle is, the question doesn't even make sense. It's the wave that takes up the space, and depending on how you poke it, it will manifest the particle here, there, or somewhere else. Okay.
Starting point is 01:11:52 Yes. Now you want to create universes in which the particle can be in those places, turning what is probabilistic, statistical, and quantum into something that's deterministic. So Einstein's quip, declaration even, because he was slow to adopt the weirdness of the quantum physics, he said, God does not play dice with the universe. and if you're in our realm, it kind of looks that way. God is playing dice with the universe, but in your realm, God has loaded the dice
Starting point is 01:12:28 and knows exactly what role is going to get because every role is happening in a universe that's out there spontaneously created in the act of the collapse of the weight function. Have I said that accurately? You have. God is playing all of the dice, all at the same time. And that's why the house always wins.
Starting point is 01:12:52 And it's just the matter. It's just a matter of which table you want to roll. That's all it is. Beautifully said, Neil. Beautifully said, Neil. Yeah, so if the casinos, if it says God's casino, stay away. So, Charles, give us a thought to take us out.
Starting point is 01:13:13 When we first thought of quantum physics, Heck, when I first took quantum physics in college, I was like, this can't be right. But that's only because I didn't have a good sense yet of reality as a whole. Today we understand, as I see more and more of reality happening, all the things that I don't understand is only what I don't understand, not how the universe works. So I'm hoping that as I continued to go in my journey of discovery and studying things like galaxies and supermassive black holes and things like that, that I am open enough to see those things
Starting point is 01:13:50 which I could never conceive of, things that in my gut I know are wrong, and yet be able over time to see that actually that is reality. And let's say yourself short there. It's not that in your gut you know it's wrong, is that in your gut, your life experience is insufficient to absorb that which stands far outside of your life experience. So it's not that it's wrong,
Starting point is 01:14:14 It's just it doesn't fit. It doesn't fit. Yeah, don't be so hard on yourself, man. I know. Thanks. These guys are the most supportive friends I could ever ask for. If I can embrace that part of me,
Starting point is 01:14:27 which I don't understand and don't know and perhaps even fear, then I'm going to be a better off in this world, and I hope all of us would share in that with me. All right. Well, thank you for that. Absolutely. Thank you for that.
Starting point is 01:14:43 Because I'd like to do. do at the end of our shows is offer a cosmic perspective, the summation of what we've discussed and perhaps a perspective on what it means for us today, tomorrow, and beyond. This as a scientist, it's kind of your job to stand at the frontier. You put a foot in what is known and a foot in what is unknown, and you sort of work your way out there. Now, what we do know is that Of course, as the area of our knowledge grows, so too does the perimeter of your ignorance. So we can feel good about what we do know, as Charles surely does.
Starting point is 01:15:28 He's worked hard for his expertise. But as you walk the perimeter, oh my gosh, there's so much more we don't know than what we do. And for me, I celebrate. the ignorance. As the German poet Rainer Maria Rilke noted, one needs to learn to love the questions themselves. Because those questions are not just, I don't know, and then walk the other way, they draw you towards paths of discovery. And what I enjoy about our world is that we have creative people who maybe took a few physics classes, maybe read your quantum handy question
Starting point is 01:16:16 book, whatever it's called. Sorry. Quantum handy that. And these are people who are creative storytellers, cinematographers, comic book illustrators, people who are not content with just the world, let's reach out to all the places science can take us and stoke our imagination beyond what is otherwise visible, just looking at what we know today. And so I celebrate the fact that we live in a world where science is accessible to enough other people who are not scientists that we can celebrate science as a fundamental part of our culture, not just an activity conducted by pointy-headed intellectuals in laboratory. And that is a cosmic perspective.
Starting point is 01:17:18 Thank you, Bill's Hall. Gary. Pleasure, my friend. Thank you so much. Keep you can see. It's not nice. That was StarTalk Live, special edition. at Guildhall, East Hampton.
Starting point is 01:17:38 Neil deGrasse Tyson here, wishing you to keep looking up.
