  • PROGRAM DESCRIPTION: Is our universe unique or one of many? What happened before the Big Bang? Why is there something rather than nothing? Physicists and cosmologists are closing in on how the universe operates at its very core. But even with powerful telescopes and particle accelerators pushed to their limits, experimenters struggle to keep up as theoreticians march forward, leaving grand theories untested. Some argue that if these deep questions can’t be answered empirically, they’re not relevant to science. Are they right? Join world-leading cosmologists, philosophers and physicists as they tackle the profound questions of existence.
    PARTICIPANTS: David Z. Albert, George F. R. Ellis, Alan Guth, Veronika Hubeny, Andrei Linde, Barry Loewer

    Gotta say, in what little she spoke, Veronika Hubeny made one hell of a case for not taking too literally the claims of the description of reality in one particular formulation of physical theories vs another. I was completely convinced by her rather uncommon statement that even the classical 3D world is necessarily more "real" than what any other (mathematically equivalent) description might suggest.

    For those of you out there who, like me, are binge watching these physics lectures and presentations - I have to say that this one, in particular, is much more tense and lively a debate than the other WSF panels. I fell asleep a quarter of the way through the first time (not uncommon as I watch before bed) because I was a little turned off by the abstract nature of the conversation but upon a second go-around, am pleasantly intrigued by this powerhouse line-up and their politely tense parsing of words - when so much seems to be on the line - i've grown a little tired of watching Brian Greene chew his own scenery and this is a nice antidote.

    Too many brilliant minds seem to forget, mathematics is merely a philosophical tool for logic and reasoning in the metaphysical realm and does not directly define the physical realm.
    All the models of the physical realm in physics are just that, models, a rendition of our current understanding of reality. Just as an artist starts off drawing gibberish to making better and better models of reality to having a good rendition of it. However, these models will always be our perception of reality and not necessarily reality itself.

    • @HurricaneSA
      @HurricaneSA Před 4 lety +8

      Time is the camera through which we view the world. It takes exactly one picture per moment that just passed. It never takes a picture of any moment other than the one that just passed. Our camera has an obvious limit in how fast it can take pictures. We call this the cosmic constant, the speed of causality or the speed of light. Since we and our camera exist inside the bubble that make up our reality we can only move through space moment by moment, which we our camera happily records as we move along. Since we are bound within this universe we are trying to observe we can never escape it and take pictures from the outside. So whether our universe is finite or infinite, for all practical purposes the part we have access to is all we will ever have access to. Now, here's the fun part. We can only ever experience the past. There is no "right now". We only notice the moment after our camera took the picture. ;)

    • @medexamtoolsdotcom
      @medexamtoolsdotcom Před 4 lety +2

      Why? It's a simple concept. It may indeed be infinite into the past too, though. And time may come to an end some time in the future after all. So neither part is necessarily true. Well, time will probably not come to an end if the big bang wasn't actually the beginning, because that would imply a sort of cyclical universe.

    • @HurricaneSA
      @HurricaneSA Před 4 lety +3

      @@medexamtoolsdotcom Time is not a thing. To illustrate, take a movie. Each frame is a moment in time but it is not time itself. Time is also not something outside of the movie (for the characters in the movie). It does not occupy the space between one frame and the next. Moving from one frame to the next is time. If I pause the movie half way and never play it again then time will stand still for the movie characters. This is exactly the same for us. Time is not some weird or mystical force. It is simply what we name the idea of moving from one moment to the next. So the real question is, will we keep moving from one moment to the next forever? If nothing destroys the universe then sure, why not? You don't need matter around for one moment to move to the next. Nobody will see it but time will still flow. Which begs the question. If a moment passed and nobody was there to see it did it happen? :p

      ?? They were on track.
      The nature of these conversations simply lends itself to the fact that many fundamental issues are related and connect to each other, and the problems physics face today which need answering are also connected. Therefore, you cannot have a rigid, straightforward track to follow in any of these types of conversations.

    So, the man who came up with inflation to satisfy the Big Bang theory, is now working on a model of an eternal universe?
    That's really impressive.
    We need more men like Alan Guth in science (and in politics?). Follow where curiosity and feasibility lead (as long as the funding lasts).

    • @GonzoTehGreat
      @GonzoTehGreat Před 2 lety

      While Guth is crediting with originally proposing the idea, he didn't come up with *Cosmological Inflation* Theory on his own. Linde and Starobinsky (amongst others) also share credit.
      It was an attempt to address problems created by *Big Bang* Theory in explaining the homogeneity of the large scale structure of the universe.
      However, instead of solving the "Fine-Tuning" problem it created it's own version of it, necessitating the need for an extension to the Theory, known as *Eternal Inflation,* which has proved to be more controversial/divisive and hence is less is widely accepted.
      Indeed, Paul Steinhardt, (mentioned at 30:27) one of Inflation's earliest proponents, who initially also supported *Eternal Inflation,* later became a critic of it and the "multiverse" predicted by it, for the reasons mentioned by David Albert (36:50) in the above video.
      Regardless, *Eternal Inflation* is a consistent continuation of the original CI Theory, so Guth hasn't altered his position about it.

  • @bobaldo2339
    @bobaldo2339 Před 5 lety +53

    A better question than "Why is there something rather than nothing?" is: "Why do we wonder why the universe exists"? Why does it seem odd to us "that there is anything at all"? And why should it ever occur to us that somehow "nothing" existing should be more likely than "something"? (Nothing or "nothingness" if you like, is a concept without a referent. There is no reason to believe that "nothing" exists, ever did in any sense exist, or ever could exist.) Could it be because human language evolved to handle human scale experience, and when we think about the entire universe in language, our concepts are just not appropriate to apply? By stretching our human-scale-evolved concepts beyond the context in which they have meaningful functionality (indulging in a "misuse of language") we tie ourselves in conceptual knots, and create what are traditionally called "metaphysical problems". It's fun, for instance, to think concepts like "being", and "nothingness" have deep meaning. They are great for the romance offered by "continental philosophy". But, in reality they are just our own language concepts fooling us into thinking their misapplication is producing profundity.
    Much as we might enjoy, or be captured by, the question, "Why is there something rather than nothing?", we would do much better to accept the fact that the likely-hood of "nothing" ever existing is zero, and the real task at hand is dealing with the "something" that does.

    • @ZigSputnik
      @ZigSputnik Před 5 lety +7

      Sadly our brains only evolved to handle problems related to survival and procreation on this planet, so there are many paradoxes which we cannot even theorise about. If understanding the origin of existence ever becomes advantageous to procreation, then we may finally have a chance! Actually I think we'll get there sooner than that by using our tools of mathematics and computing, but whether we will really 'understand' it, I'm not so sure.

    • @jerrygump1422

      Very true, it isn't brought up nearly enough, and it's the most elegant solution I've heard yet. The only one that makes any sense to me, at least. Though I think people shy away from it for a reason. Penrose inserted some bits to try and allow it to be proven, which seem to have turned out not quite right. Echoes of supermassive black holes in the cosmic microwave background, for example. Maybe it's my own lack of knowledge, but I still can't see why features like that would make it through to the other side. I can understand the desire to have it be provable, but I think he might have gone about it the wrong way, and it ended up being prematurely discredited.
      Here's to hoping smarter minds than mine at least give it fair consideration.

    • @aitch9053
      @aitch9053 Před 5 lety +4

      More like Big Bang -> Big Freeze -> Big Bang. As I understand it, after having read the book : All the matter in the universe will keep going in accelerated expansion and eventually decay into extremely diffuse redshifted radiation. (The "Big Freeze / Heat Death" theory.) But once all the particles with mass are gone, standard mechanics break down. The energy field starts acting like a singularity of sorts, because there's no real way for time or distance to exist. This puts all the energy in the universe into what equates to no space and kick starts the big bang. Nothing lost, nothing gained, but probably turns out differently each time.

      I don't even care whether that's scientifically sensible , but for my personal peace of mind , it simply suffices . I'm crap in differential equations , that's why i flunked , ages ago .

      The sad thing is science will never adequately address the Greatest of the Great Questions of Life: "Why Bother?" That is a question for philosophy. (I've answered it adequately - read my philosophy). Science cannot even answer the Second Greatest Question of Life: "Now What?" That is also a philosophical question. Engineering answers the Fourth Greatest Question of Life: "How?" The Third Greatest Question of Life is "What is Out There?" which is the realm of science, which many philosophers do not understand, offering silly speculations as answers rather than mere wild possibilities.

I can imagine that in the not too distant future, there may be people along with a means to embelish their cognitive reach who will have the means to know more about the universe. I hope that we can survive our harmful propensities, so as to be able to observe as well as to explore a greater portion of what are our numerous current unknowns.

    In particle physics, a photon has no one point in space while it's in wave form. But if the wave is interfered with, then the placement of the photon is known.
    If you use this idea when dealing with space/time, the outcome is the same. We cannot know the future, because there has been no interference from the events in the now. Only until the collapse of the time wave can we come into contact with the new reality.
    In mathematics, a physicist can create a probability graph based on known information. He then can use that information to determine where something ought to be. Still, until he can test his information, he cannot know whether or not he's right. So in this state, the physicist is building a house on an uncertain ground.

      As a layperson, my understanding is that the waveform is a probability curve. It should not be interpreted as being in all places at the same time, but a particle has certain chance of being anywhere in the curve when it is measured.

      Well yes, and no. According to Schroeder's cat theorem, a particle can be in one place or in any place. But we can't know where the exact placement of a particle until we measure it. It's true that you could create a extrapolation of where the particle may be, but until you interfere with the quantum wave, you cannot know for certain.

It's only at that time when we know where it exists. When you're not looking at something is that thing not happening soley because you're unaware of it ?

    If you can prove that you've taken a step and also that you haven't moved - then you have proved infinity. Eg divide with multiple subtraction by zero 1/0 = count(1-0-0-0...). The moment you do the first subtraction and know that the next step is the same as the first, you know that you are looking at literal infinity. Sure, it may exist, you just can't get there from here.

She responded "what about infinity and one, what about infinity and two...." I told her that infinity is a hypothetical construct. She asked, "what is a hypothetical construct?"

    In fact, zero can only be perceived by using infinity to approach zero in mathematics.
    Even black holes are finite and will eventually die.
    Perhaps the reason for quantisation in particle physics is because we have found the smallest chunks of reality (spacetime)...

      What your are despairing about is Continued Universal Human Cluelessness (which I've developed a new philosophy of survival and morality in response to - read it - it offers Final Enlightenment) (you can throw your Zen into the dustbin of history - it is child's play).
      Here is a sample of Final Enlightenment: The Ultimate Value of Life is Enlightened Higher Consciousness - enlightened by my philosophy, and the 'higher consciousness' being what humans are endowed with (but waste).
      The Ultimate Goal of Life is to secure the Ultimate Value of Life, in this case securing enlightened higher consciousness in a harsh and deadly universe (the harshness and deadliness of which has been verified).
      Wording that differently, 'securing' means defeating natural and unnatural death, and pursuing resurrection technology.
      My philosophy began by answering the Greatest of the Great Questions of Life, "Why Bother?" (because consciousness is a good thing - worth working for and preserving), and "Now What?" which my Strategies of Broader Survival address at the second highest level. It continued developing its specific structure with The Third Greatest Question of Life is "What threats and benefits to life are out there?" which is what science addresses (discovery), while engineering addresses the Fourth and Fifth Greatest Questions of Life: "What can we do about it?" and "How?"
      Finally, my philosophy created the Ultimate Determining Factor between Good and Evil (the 'morality' aspect), which is the Ultimate Goal of Life, since I discovered (thank you) that Good and Evil are based on Goals (go ahead and think it through).
