    In an infinite universe is there a version of this video where the camera doesn't keep moving around in a distracting manner?

    Dr Guth the multiverse theory by inflation is a fascinating theory and is probably correct. I wonder if this could some how be incorporated with the holographic principle of the universe,I love following your work sir and it certainly keeps my mind wondering of the true reality of our world and beyond.

    What implications would a mostly homogenous inflation field (like cosmic microwave background), with energy fluctuations leading to multiple universes, have for infinity and probability in a multiverse?

  • @roblloyd2609
    @roblloyd2609 6 ปีที่แล้ว +1

    I like to think that multiverse or divergent universes that are created every time a decision is made in effect gives us infinite existence, so today you die but you don't know you died as at that moment your consciousness still exists in multiple or divergent universes. If you've ever done acid that existance seems obvious.

    • @roblloyd2609
      @roblloyd2609 6 ปีที่แล้ว

      rubiks6 I said I like to 'think that'; I not said it's possible. However, more and more exotic ideas in physics are being suggested. And certainly in an infinite amount of universes with infinite possibilities then anything is infinitely possible as you can't have infinitely impossible if infinite universes exist.
      Even in this universe there are multiple me's that exist but exist in different time/space. We are just aware of the now and memory of the past but Einstein says that past space/time exists we just don't know how to get there.

    • @roblloyd2609
      @roblloyd2609 6 ปีที่แล้ว +1

      rubiks6 who are the we that are wasting our mental capacities. I have no physics or mathematics background other than watching documentaries and reading science magazines. In that way I'm broadening my mind. I'm certainly not wasting my time trying to write a thesis on this subject. But thinking about or dreaming about also expands your minds.

    The universe is just a product of nature. Nature is the very definition of our universe, it is a misunderstood yet understood thing. It is a paradox in that everything exist and nothing exist.

  • @henrirauhala4335
    @henrirauhala4335 6 ปีที่แล้ว

    Guth makes a generalisation about physics, that all physics should be "propabilistic" by nature, because quantum mechanics is. However, this is not necessary, especially since there's no reason to assume quantum mechanics to be "underlying" everything. We don't know how deep levels exist in matter, if there's any limit at all. Quantum mechanics is the deepest level we have explored so far. Anyway, if we can't determine propabilities in an infinite cosmos, then we can't. Simply because it's inconvenient, we can't say that an infinite cosmos doesn't exist.

    He's one of the most interesting folks to listen to. There's an infinite number of four-headed cows being born at every given instant... even if there's no now here, there, it's still some time there. I just don't think I'm a Boltzmann brain, even though it's more likely for me to be one than a regular person.

  • @simoncarlile5190
    @simoncarlile5190 6 ปีที่แล้ว

    He didn't really address uncountable infinities such as the real numbers. You can't order them because they (A) have no starting point and (B) have no way to iterate to the "next" element. It's not terribly different from the situation of having an infinite number of universes that can't be sensibly ordered.

    I guess that in an infinite number of universes where anything that can happen happens an infinite number of times, there must be an infinite number of universes that are governed by an intelligent consciousness, call it what you like, that then takes over all other universes not yet governed by consciousness an infinite number of times. Plus I’m also wondering if there’s a Disneyland universe with all the characters out there as well then, and perhaps even one where endless numbers of fully functional 747’s spontaneously pop into existence from nowhere? With an infinite number of combinations of natural laws and possibilities both the imaginable and unimaginable must occur an endless number of times. Where did Occam disappear? At least we know that intelligence and consciousness exist, and the leap to consciousness as fundamental to existence somehow seems simpler, and you can still fit all infinitely possible universes into that consciousness as thoughts, or if you prefer to call it simulations.

    • @lepidoptera9337
      @lepidoptera9337 3 ปีที่แล้ว

      No, that's not even a good mathematical argument. For one thing all of these "parallel" universes are limited by some kinds of laws of nature. They may not be the same as in our part of the universe, but they are still strong limits. Hence there is never a scenario where anything can happen. It will, more or less, all be boring physics as usual. No giant flying castles for you. Even within the probability argument you are running up against the fact that number of physically allowed possibilities greatly outnumbers the number of possible universes, hence the set of actually existing universes is always a null-subset of the set of all possible universes.

    • @lepidoptera9337
      @lepidoptera9337 3 ปีที่แล้ว

      That, too, is a random assumption. If we vary the parameters of the standard model of particle physics, then what we find is that most possible universes of this kind are simply empty. They don't produce stable matter and are completely radiation dominated. That is the opposite of random. These are (thermodynamically) highly ordered, but extremely boring universes.

    I don't get why measuring probability would be important or even why we need bother (in the sort of universe discussed in the film). In fact, the concept (probability) in this context looks meaningless.

  • @mackdmara
    @mackdmara 6 ปีที่แล้ว

    The issue I always see in this is this. If you could have an infinite amount of cows, then he is right. Not even in this universe is that possible. It is not infinite like that. Thus, if I push proportions out of context, of course there is no difference. The issue is not what would happen if nothing had limits, but rather what happens when you do. Why? Because the Universe has limits, so does time, so does everything we will even encounter in the natural world. To find a real infinity, you would be talking God. Even then, you are talking about a person that we could never have proper language for the nature of. How can you define (limit) the infinite (limitless)?
    Either way, I trust they know what they are doing.

    The resolution is trivial: science is only required to describe what is observable. It is not required to read the theoretical tea leaves of what else could be. That's religion's "expertise". You want to believe in the unseen? Start a church and take advantage of tax savings, but don't call it "science".
