Is there any real way to disprove the Boltzmann brain?

Is there any real way to disprove the Boltzmann brain? I know eggheads like to dismiss it as pseudoscience, but doesn't it make a lot of sense?

      if the universe is infinite then this thing is out there somewhere. Maybe it feeds on boltzmann brains too. I'm going to assume that it does

        No. Its a common mistake to believe Infinite universe equals universe in which everything happens. Whatever is not compatible with laws of physics for example, will not happen.

          Imagination isn't necessarily compatible with the laws of physics, can you not imagine or something?

            Except its not and comic books clearly prove people can imagine things that are incompatible or even the exact opposite of physical laws.

            Imagination is compatible. If you can imagine something that doesn't mean it can exist. I can imagine I have -50 apples, there is no such thing as -50 apples.

    No. It's real and you are doomed to an eternity of incarnating as random creatures in a random universe for eternity. Enjoy these few seconds you have as a human because they might be the only few you have to actually introspect on the matter.

    Statistically speaking the patterns you notice can be explained in a simpler way using the established world model than by assuming a Boltzmann brain.
    So you disprove the Boltzmann brain using Occam's razor (or rather an advanced version of it).

      Yeah but isn't it easier to just presume that literally all of this shit is just a dream. (which essentially I guess is what the Boltzmann model boils down to)

        No, occam's razor validates boltzmann brain since its much more simple to just say its all imaginary than to try to come up with some consistent unified theory of physics to explain everything.

        No it isn't. Formally speaking (I haven't thought this through) the world model any given agent should assume to be true is the one which explains the given facts in the simplest manner (i.e. fewest axioms/degrees of arbitrariness).

        By saying it's all a dream you do not reduce the realm of possible worlds P={world|world is possible} in a justified manner.
        I think it would be an interesting venue to think about what such a justification would entail, because this is in a sense the opposite way to address the problem to the above: Reducing the amount of possible states in a justified way instead of explaining the current state by a coherent model.

          Note: This hand-wavy formalization of occam's razor may relate to Solomonoff inference

    Boltzmann brain from quantum fluctuations makes me laugh. Every 10^10^50 years in a perfect vacuum a brain would from long enough to form a conscious thought only then to disappear.

    Personally i think its totally fricking moronic , but it is interesting

      If the universe is infinite, and you agree that given enough time a consciously thinking brain can form, then aren't you inadvertently concurring with the theory?

        I believe just by observing the nature of a infinite universe the possibility for such things to occur is therefore not zero. However i think this isnt the first time the idea of infinity has been stretched to include utter nonsense - I do not think a brain will ever magically spawn out of a vacuum , i do believe in quantum fluctuations however that is due to the nature of the fabric of spacetime. I just think , this "brain" is a thought experiment and will forever be a thought experiment.

          Why not? Didn't the universe itself do that?

            If you are arguing in Boltzmann brain terms then there's no space, time, universe or maths to speak of. These are all part of the illusion of your illusory brain. The argument inevitably descends into absurdity. Is it a possibility? Yes. Is it worthwhile to discuss? No. That's why no one talks about it.

            You seem hung up on the brain being made of other material things, so what if it were a boltzmann mind instead of a brain?

            Also every formal system descends into absurdity, its why the base value in math is itself multiplied by itself indefinitely and the largest possible value plateaus at a value that is also itself multiplied by itself indefinitely.

            Math is an abstract concept, just like your boltzmann brain

            Every language, communication standard, and formal system is an abstraction, absurdity is baked into everything, so pointing out when something is absurd or abstract isn't very helpful and doesn't prove anything one way or the other.

            I don't know, nobody can show me one way or another, non belief is an absurd paradox because if I don't really believe in anything, I couldn't really believe in bolzmann brains, but that also means I believe in nothing and if a boltzmann brain is an emergent phenomenon of nothing, it must follow that by believing in nothing I also believe in boltzmann brains through the process of not really believing anything.

        This is the main value of Boltzmann brains: If your theory predicts the typical observer will be a Boltzmann brain, you, presuming yourself a typical observer, discard that theory.

          Why though? Forgive me if I'm being stupid here and missing something obvious (I'm a little drunk), but why should we dismiss something just because its unlikely and being spawned by something incredibly unlikely. If it's the only possible reason for something to exist, and it has been given enough time to exist, then surely it's still the only possible outcome.

            The point is not dismissing the logic that tells you that a certain model of the universe results in more Boltzmann brains than regular brains. It is accepting that logic, noting that being regular brains is a better model for our observations, and then using that to rule out those models of the universe, under the assumption that we are typical observers.

      Yeah you'd think at like 2 kelvin the brain would be totally frozen and unable to function anyway

    Not without a philosophical or logical overhaul to the models which fall prey to them. It's not pseudoscience, it's the only rational conclusion (not that they are merely possible but that YOU ARE LITERALLY NOW ONE) on many models.

    The whole point of boltzmann brain discussion is that it defeats empiricism since these entities are infinitely more likely than what we (think) we actually are.

    Boltzmann brains is like the Big Bang and Shrodinger's Cat.
    Criticism which show the absurdity of the idea.
    >what, you think the universe came into being in some kind of big bang?
    >what, you think the cat is both dead and alive in the box?
    >what, you think that statistics show that brains can spontaneously appear?

    I propose the Boltzmann troonyvegana.
    The Boltzman troonyvegana is a human torso, no head, no arms, no legs, just a torso, and it has a penis with testicles and a vegana with a uterus.
    And these torsos spontaneously appear in the universe (because of statistics), and some of them bounce into each other and impregnate one another.
    This leads to two populations, one of spontaneously generated torsos and torsos which appear from reproduction.
    And because there a difference between populations, a class system develops.
    And the old spontaneously generated torsos learn how to control the torsos which are produced by reproduction, because time is a thing.
    The Boltzmann troonyvegana is to show that now matter how you morons think about shit, you will never win The Game.

    There is no way unless you assume either one of the following:
    1. the universe is not infinite in time (into the future). I.e., at one point it definitely will "die" (heat death) for eternity.
    2. the universe is not spatially infinite.

    2. is extremely hard to assume. Or in other words, it's an extremely bold claim to say the universe (provided it's not a hypershere that loops back on itself) is bounded. There is nothing to suggest it has to be. "Nothing suggests X has to be Y" unfortunately mathematically often means "X is not-Y", and the realm we are currently discussing is so "primitive" (as in ontologically irreducible) that it's actually more correct to regard this as a discussion about mathematics-as-reality. This is not a dragons-under-my-bed scenario, where just because "nothing suggests there isn't a dragon under my bed", there actually *must exist* a dragon under my bed.

    So we have to put our hopes into 1.: there will definitely come a heat death. I think this is the explanation why there will be no Boltzman brains. The number of actual brains greatly outnumbers the paltry handful that will randomly pop up over the eons in a dying or already heat dead universe. This isn't even defeated by the fact that the Boltzman brains have an infinite future to work with, because the ability for new B-Brains to be generated is an evolving function that tends towards an asymptote, i.e. the ability for new B-Brains to pop up is constantly diminishing.

    Objection I hear is that your theory and mechanism go out the window when you assume that you are delusional as a premise—if you are a Boltzmann brain, how could you possibly have deduced that you are one?

    So a brain made of matter popping into existence due to quantum fluctuations is absurd. But a universe spawning due to quantum fluctuations with 10^50 times more mass that also containts a gazillion copies of brains is not absurd?
