    This kind of video sparks wonder in my mind in a way I recognize from when I was young and first started watching science videos (Sagan, Clarke, others). If adulthood is so often criticized for lacking the imagination and wonder of youth, I for one feel that effect countered when I follow along with newer ideas about origins. Now I can hardly go about my day without perceiving all that I see, as bound energy. Thanks, Arvin!

      I'd find it even more comforting if certain self-centered members of our species could get that thought through their thick skulls.
      More and more, we learn that our little oasis of spacetime is minuscule, finite, fragile, and completely unimportant to anything outside of it. Could we maybe not burn it all up trying to prove who has the bigger d*ck?

    This is legit the best inflationary multiverse explanation ever. The end of inflation, locally is the thing I was trying to understand and it was conveyed beautifully with the animation you showed ( and also giving analogy to the radioactive decay). Also, the point that the laws of physics can be completely different in all those pocket universe. Thanks for the video man, really appreciate it.

  • @johnkotches8320

    I *think* I understand the topic. The end of inflation, "locally", is the moment our universe's bubble separates from the ongoing expansion to be a discete universe.
    Thank you for touching on the possibility that in these multiverses the local laws of physics could be radically different. Given the isolation of the various universes, it's not something we can know.
    As someone who isn't a theoretical cosmologist/astrophysicist I appreciate your ability to present vastly complicated topics at understandable levels for those of us who haven't made it our life's work.

It's not a matter of "our telescopes are not powerful enough", it's actually impossible for anything that happens outside a certain volume to have any effect on us, because it's receding away faster that the speed of light, which = the speed of causality. So in a sense they may as well be bubble universes, even though they aren't *literally*.

    Massive amount of other Universes may be the solution to "Fine Tuning" mistery.
    If the number of the Universes, both, those that currently exist, and those that have already disintegrated, was large enough - then there is no "divine plan", only the calculation of the probability, that in the end there was one (Ours) with physical constants arranged in such a way as to favor the long time existence and even the rise of life.
    Just simple process of evolution - many have to die, in order to finally come up with something that has a chance to survive.

      It's best to think of energy as a physical thing. A lot of field theories such as electromagnetism and general relativity use the concept of fields storing energy and momentum.

      Do you mean if speed of light is different in the space between universe, then could we detect them? Unlikely since the speed of light would not change in our universe, but I will add the caveat that we would need to understand the overarching laws of physics that is constant in the multiverse. It is possible that there is some loophole there that allows this kind of communication. Or, as I pointed out in the video, Wormholes may be able to connect two different universes - but again, this is a stretch is unlikely to be realistic.

      The answer to that is yes. It's possible for two universes to form so close (and the distance between them would have to be microscopic) that they collide. There are a few patterns in the cosmic background radiation that might be the result of a collision, but they're currently only at about a 95% statistical significance, which is not high enough for a new discovery in cosmology.

    Very nice video, is the first time I read about this theory on how multiverses could be real.
    Like I said on the previous video, I first had a feeling my might like the idea of a multiverse because of saying, a universe has no edge.
    This video actually can show a universe bubble actually might have an edge and yes, even a center.
    Look at 7:47 in the video.
    We have many bubbles, but each bubble has a clear edge of THAT bubble, not of the space itself. Space itself that expand faster than the speed of light is fine. So the fabric of space itself might not have an edge, again, extremely hard to proof or disprove, bubbles within the space, the universe should in this case have an edge.
    It is just so complex so mindblowing, and the fun part is, we could have it ALL wrong also, haha. :)
    What is actually the most mindblowing is how huge the multiverse can be.

      @harrkev 2 роки тому +4

      Cosmologists love infinities. So, if the multiverse exists, then there logically must have been an infinite number of them in the past, and an infinite number of them in the future. Given that it is expanding very, very fast, and started an infinite amount of time ago, then these infinities are the only option. If you exclude a creator, then you exclude a first cause, so everything pretty much has to go on forever, leading to infinite everything.
      But don't worry. The odds are that you are a Boltzman brain, and will be dead in a few seconds. Look it up. It makes NO sense, but logically must be true given that everything is infinite.

      By looking at the expansion rates of objects we can observe, and extrapolating that to assume other parts of the universe we observe, likely behave the same way. Light, or electromagnetic energy, is our central medium of existence. There could be places between universes, where electromagnetism is limited. Gravity causes such an effect, and lenses light around massive stellar objects.
      To consider the influence of dark matter, the mysterious gravitational pull from unseen matter, this is a possible explanation.

  • @NVidea-yz1fg

    What causes the bubble to stop to rapidly inflate and to just expand? Could that be gravity? What I am thinking is, when the bubble appears as a single point in the inflating "multiverse inflation field", maybe it just keeps inflating _with_ it. Until something happens, i.e. gravity emerges - which then slows down the inflation. Similar to how gravity keeps galaxies together while the universe still expands.

    • @ArvinAsh

    Can it be possible that inflation is 'the' mechanism that produces the locality principle? I mean, before inflation, every point in the space was connected, hence they were close to each other. When the localization process started, many of those links broke so that only the local links survived, hence the universe seemed like it was inflated. This explains the source of energy for inflation, too.

    I have a thought, on which I'd like to know what you'd say. When a bubble is formed, it moves apart from one another or the space between them expands making these bubbles move apart. So, is there any chance if at all these bubbles collide with prior bubble or not? Also, if at all these collide, what would be the outcome? Will it cease to exist or could it be, that there can be a possibility for an worm hole to exist.

    For instance, a Google search says that there is 10^53 kg of mass in the observable universe. To get energy I multiply by c^2 which gives me 3x10^61 Joules, which then converted to eV is 1.9x10^80 eV.
    But in the video at 11:33 it says the energy at the Big Bang is 10^24 eV.
    Are my calculations incorrect?
    Edit: it occurs to me, too, that the number should be even larger than what I calculated since not all the energy at the big bang would be in the form of mass.

    Wow. That theory has a lot going for it and patches a lot of holes in BBT. My immediate first question is then: how does this relate to the condensation of matter - does this also explain that? Does the energy come from the "freezing" of the inflation field? As in, the energy which was powering the expansion gets dumped into our spacetime as that expansion halted locally - like how slamming the breaks on a vehicle transforms the kinetic energy into heat and other forms. Or are there other candidates for that energy from somewhere else?

I believe it's quantum tunneling that allowed point B to be overcome and move to C on the graph. For 10-³⁶seconds inflation continued exponentially in our bubble the stopped. However because of quantum imperfections in the field some parts will continue on in exponential inflation which will spawn more bubbles and more inflation field in-between the bubbles.

    And listen to what I just mentioned in the previous comment, I have a theory, as you mentioned space-time always expands. For example, we know that in space-time quarks are being made and go away instantly.
    So we can use three facts.
    Fact number one is that an empty space works are being made and disappear.
    Fact number two is that everything that has mass has gravity.
    Fact number three is that everything that has gravity has time. And everything that has mass and gravity bends both space-time and light.
    From the three facts above we can possibly identify that dark matter is simply the gravity that is produced from quarks appearing and disappearing. If you consider quarks that are disappearing and appearing as a constant physical phenomenon then there is a constant availability of mass.
    We also know or fact number for that everything in the universe is mass which is also equal to energy and everything in the universe is made of vibrations. We also know that the cosmic microwave background shows that the coldest spot in the universe is not 0° kelvin which means that there is some temperature coming out of nothing. We know that space and it’s coldest area is 0.2° kelvin. This temperature is a result of dark matter producing/losing some of its energy to space-time and thus creating a minute temperature.
