Cosmic Queries - Intergalactic Impacts with Neil deGrasse Tyson

Ғылым және технология

What happens when three black holes collide? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice explore even more cosmic collisions in space, in the quantum realm, and more!
Do photons experience time? We think about all the unseen photons and the science of lightsabers. Photons can cross but not hit each other? Can you make light interact with itself? We discuss: Could there be a time particle? What’s the smallest unit of space? Learn about the quantum field: Could dropping the temperature slow a radioactive element’s half-life? Could you keep food in the freezer forever?
Could the moons of outer planets have been born from inner rocky planets that were ejected? What should qualify as a moon? We know what the collision of two black holes is like, what about three? Find out the history of Albert Einstein, gravitational waves, and lasers. How frequently do black holes collide?
Could you join two bodies of ice together in a collision? Do any of these space collisions show light when they happen? Discover the electromagnetic spectrum, sonic booms, and the science behind why diamonds sparkle. All that, plus, are atoms actually just tiny solar systems?

    One of the latest images from the James Webb Space Telescope depicts a cosmic collision-Stephan's Quintet is a visual grouping of five interacting galaxies, two of which are actively colliding, swapping gas, dust and stars in the process and even creating a shockwave!

    Neil has mentioned multiple times throughout ST that a photon doesn't experience time. But wondering if a photon knows its destination 13.5 billion years into the future is kind of a cool concept. We step outside and feel the warmth of the Sun, but the photon that just hit your face was 100,000 to 1,000,000 years in the making deep inside the Sun. Once it manages to escape the Sun's layers, it immediately knows where you will be eight minutes in its future (8 light minutes to reach you), but while that knowledge is instantaneous to the photon, we still have to travel through space and time for eight minutes for the photon to get there. Add to that relativity, which I'm not smart enough to speak about, but I've done the calculations to account for the expansion of space over great distances (negligible for a photon from the Sun). So does that mean we are where we are supposed to be because a photon emitted was meant to collide there? Personally I don't think so lol but it's a cool thought.

    It is a good question, and the "experiencing time all at once" perspective of the photon reminds me of a Feynman story. In 1940, John Wheeler called Richard Feynman one day because he had a profound thought. He said, “Feynman, I know why all electrons have the same charge and the same mass” “Why?” “Because, they are all the same electron!”. (I believe this relates to the "experiencing all time at once" thought, I could be wrong) Feynman said he got the idea that positrons could simply be represented as electrons going from the future to the past in a back section of their world lines from this conversation. source: Richard P.

    Also I'd like to quote Richard Dawkins, from a short essay called 'The Real Romance In The Stars' It's ostensibly about the fraudulent nature of astrology and how it cheapens the majesty of astronomy. But it contains a mention of a collision of epic scale and sends shivers down my spine, while getting me a little choked up tbh. _The sun, when you see it, is only eight minutes ago. But look through a large telescope at the sombrero Galaxy and you are seeing a trillion suns as they were when your tailed ancestors peered shyly through the canopy and India collided with Asia to raise the Himalayas. A collision on a larger scale, between two galaxies in Stephan's Quintet, is shown to us at a time when on Earth dinosaurs were dawning and the trilobites fresh dead._

    Can we make an analogy about the photon that goes from the star to your eye like a sleeping person ? The person can be moved anywhere and wake up in different places while sleeping. But when the person wakes up, he doesn't "feel" the time that has passed, because of the speed. So basically he just awakes at the destination in a "fraction". Wouldn't this be an analogy ? so basically the photon does not "feel" the time...because of his speed, the time is standing still, for it. For someone who is sleeping on a car compared to the driver, the driver drives 2 hours, and the person sleeping feels like he traveled in an instant.

    As Leibniz put it: “If an ontological theory implies the existence of two scenarios that are empirically indistinguishable in principle but ontologically distinct ... then the ontological theory should be rejected and replaced with one relative to which the two scenarios are ontologically identical.” In other words, if a theory describes two situations as being distinct, and yet also implies that there is no conceivable way, empirically, to tell them apart, then that theory contains some superfluous and arbitrary elements that ought to be removed. Leibniz’s prescription is, of course, widely accepted by most physicists today. The idea exerted a powerful influence over later thinkers, including Poincaré and Einstein, and helped lead to the theories of special and general relativity. And this idea, Spekkens suggests, may still hold further value for questions at the frontiers of today’s physics. Leibniz’s correspondent Clarke objected to his view, suggesting an exception. A man riding inside a boat, he argued, may not detect its motion, yet that motion is obviously real enough. Leibniz countered that such motion is real because it can be detected by someone, even if it isn’t actually detected in some particular case. “Motion does not indeed depend upon being observed,” he wrote, “but it does depend upon being possible to be observed ... when there is no change that can be observed, there is no change at all.” In this, Leibniz was arguing against prevailing ideas of the time, and against Newton, who conceived of space and time in absolute terms. “I have said more than once,” Leibniz wrote, “that I hold space to be something merely relative.” Einstein, of course, followed Leibniz’s principle when he noticed that the equations of electricity and magnetism make no reference to any absolute sense of motion, but only to relative motion. A conducting wire moving through the field of a magnet seems like a distinct situation from a magnet moving past a stationary wire. Yet the two situations are in fact empirically identical, and should, Einstein concluded, be considered as such. Demanding as much leads to the Lorentz transformation as the proper way to link descriptions in reference frames in relative motion. From this, one finds a host of highly counter-intuitive effects, including time dilation. Einstein again followed Leibniz on his way to general relativity. In this case, the indistinguishability of two distinct situations - a body at rest in the absence of a gravitational field, or in free fall within a field - implied the impossibility of referring to any concept of absolute acceleration. In a 1922 lecture, Einstein recalled the moment of his discovery: “The breakthrough came suddenly one day. I was sitting on a chair in my patent office in Bern. Suddenly the thought struck me: If a man falls freely, he would not feel his own weight. I was taken aback. This simple thought experiment made a deep impression on me. This led me to the theory of gravity.” 🆒️

    Leibniz now mostly inhabits scientific history books, his ideas receiving scant attention in actual research. And yet, Spekkens argues, Leibniz’s principle concerning indistinguishability may be as useful as ever, especially when confronting foundational issues in physics. Consider the interpretation of quantum theory, where theorists remain separated into two opposing groups, loosely associated with the terms realism and empiricism. Although Leibniz’s principle can’t offer any way to unify the two groups, Spekkens argues, it might help them focus their attention on the most important issues dividing them, where progress might be made. For example, one particular interpretation comes in the form of so-called pilot-wave theories, in which electrons and other particles follow precise but highly non-classical trajectories under the influence of a quantum potential, which produces the wave-like nature of quantum dynamics. These theories demonstrate by explicit example that nothing in quantum physics prohibits thinking about particles moving along well-defined trajectories. But the theory does require the existence of some absolute rest frame, while also implying that this frame can never be detected. Many other aspects of such theories also remain unconstrained by empirical data. Hence, one might take Leibniz’s principle as coming down against such theories. On the other hand, Spekkens points out, Leibniz’s principle demands that distinct states be, in Leibniz’s own words, “empirically indistinguishable in principle,” and achieving such certainty is not easy. If several states appear indistinguishable now, future experiments might turn up measurable differences between them. So a proponent of the pilot-wave approach might agree with Leibniz’s principle, but still reject its application just yet. The aim of research, from this point of view, ought to be to seek out such evidence, or at least envision the conditions under which it might be obtained. And in this sense, Spekkens notes, Leibniz’s principle also offers some criticism of theorists from the empirical school, who object to pilot-wave or other realist interpretations of quantum theory for containing unmeasurable quantities. It implies, as he puts it, that the empiricists’ “set of mental tools is too impoverished.” After all, progress in physics often requires imagination, and creative exploration of possible distinguishing features that have not yet been measured, or even thought to exist. Progress requires scientists to “entertain ontological hypotheses, expressed with concepts that are not defined purely in terms of empirical phenomena.” Science thrives on the essential tension existing at the boundary between empirical observation and unconstrained imagination. Incredibly, Leibniz perceived that more than 300 years ago.

    Another fascinating episode, gentlemen! Thank you very much. And thanks for the folks who sent in these excellent questions! However... When listening to your answers, some fresh, related questions came to mind: - About photons: Light that reaches us from very remote galaxies is red-shifted, right? Because, a) those galaxies are moving away from us at significant fractions of the speed of light. But also b) the space traversed by the photon on its way to us is expanding. Is it possible that, through the combined effects of a & b, photons travelling inward from galaxies on the Hubble Horizon (which is itself moving away from us at the speed of light) are red-shifted to a _negative_ wavelength??? Or would they get 'stuck' when their stretched wavelength hits infinity? Could this be the source of Dark Energy? - Dark Matter: I believe there is _no_ Dark Matter. Dark Gravity is a much better term, yes. That has been observed in various ways. I propose that Dark Gravity is simply gravity leaking into our universe from _other universes._ Call it 'Foreign Gravity'. This would explain a lot, would it not? The distribution of matter, of mass, in potentially a vast number of other universes, would influence the distribution of matter in our universe in exactly the same way we see 'Dark Matter' do. Also the mystery of the Coma Cluster, where two galaxies collided head-on, a 'while' ago, and we can observe how the visible matter clearly and strongly interacted, slowing the two galaxies down. But the 'Dark Matter' does not seem to have slowed down by quite so much. This would make sense if the two corresponding clouds of 'Dark Matter' are in _different_ other universes. No direct / strong gravitational interaction between them, in that case, only the much weaker inter-universal gravitational interaction of this 'Foreign Gravity'. And, if the 'Fecund Universe' theory proves to be right, that is, every black hole that is created in our universe is also the birth, the big bang, of a 'child' universe, then through the weak inter-universe gravitational interaction, the child-universe would to some extent inherit the distribution of matter from its parent-universe. - Phobos & Deimos are also orbiting Mars in the 'wrong' direction. They are clearly captured asteroids. Should we keep calling bodies like these moons? Not sure... - Particles from Meteorite Impacts: But... Wait... Light is created in such an event. Photons are particles, right? Sort of... But even if those don't count, what about alpha- or beta-radiation? Particles for sure. But i guess those are not _created_ by the impact. They already exist, in some form, on the surface or in the meteorite, and are then just released, ejected, emitted, by the impact-energy.

That movie "Limitless" was a great example for explaining time because time in a value of a different relm is obviously different for the one who controls time in all. Love the show.

    The photons perspective on time is merely different from our perspective on time, we're not experiencing two different realities. If there were an object that experienced time slower than us and light, it would still experience the same outcome and reality as everyone else that's experiencing time faster or not at all. Between us, the slower object, and the photon, we all share the same reality and outcome just perceived from different time scales. When you swat at a fly and it disappears that doesn't mean that when it lands on your shoulder it was determinism, you and the fly just perceive things differently. To you it's a blur, but to it you're barely moving at all. You both arrive at the same reality.

    exactly. Increase in pressure increases the melting point, not the opposite which the question suggests. A drop in pressure might however change a solid to a liquid, thereby increasing the chance for a cold-welding.

It would be nice if our scientists of today would come up with a name for our most important Satellite and make it official. It almost feels like our moon is not worthy enough to carry it's own official name. 😟🥲 Professor de Grasse Tyson would be the perfect person to do so in my opinion.

    The thing is that the photon was not just emitted "X million years ago", it was emitted "X million years ago X million light years away". And "X million years ago X million light years away" is not in the past, it is "now" as it could not be observed here before now. This comes from the fast the c is not the speed of light, it is the speed of causality propagating in space.

    Another way to see it: Right before the photon hit the eye of the observer on Earth, from the point of view of the observer, the photon doesn't exist yet i.e. it still wasn't emitted. That's because the photon and the point from which it is emitted on a distant star aren't in the past light cone of the observer. In a way they aren't yet in the observable universe of the observer. Therefore the observer isn't influenced by them and as far as the observer could know they do not exist, yet. At the precise moment the photon hits the eye of the observer, the photon , the path it took and its emission point all enter in the light cone of the observer.

    that first question about the photon is interesting, it's born in an instant, and travels for eternity before hitting something, all while experiencing no time. Is a photon predetermined to have hit your eyeball though? no, because it's entire existance was darkness, so it had no awareness of your eye until it had reached there. and now y'all got me Personifying particals....great Also keep in mind that photons ARE subject to gravity. so here a photon is not even knowing it's own existance or travel for thousands of years when suddenly it gets pulled in a different direction by a black hole, or sun, or planet, moon etc... constantly getting yanked back and forth until finally coming to a stop and experiencing time for the first moment

    ​@@shanecombs1993 I thought (and hoped) the same way back when. I liked the romantic/poetic nature it allowed for infinite death and rebirth. By the way, that hypothesis is referred to as "the big crunch" unforunutatley it has largely been rejected in favor of "the heat death" based on the universe expanding (and speeding up) greater than the force of gravity. Still I don't see why blackholes couldn't trigger the creation of new universes. There is the hypothesis of black holes that they emit radiation (look up hawking radiation) and if they didn't consume matter for long enough could revert to their state before being a blackhole.... it's way above me. so is the thing about blackholes being wormholes through time and space into the past..... Anyways, still hold the idea that blackholes themselves could be trigger events for the creation of new universes outside our own, and multiverse theory allows for multiple universes existing like a froth of bubbles, even while they expand and push on other universes, they never interact of affect one another.
