    Was an incredible drop in entropy responsible for the Big Bang? If that’s the case, this would lead us to conclude that a great many other things are possible, including the likelihood that you are a Boltzmann Brain. Try The Great Courses Plus at ow.ly/4anY30acloO

    The Oh My God Particle
    • The Oh My God Particle
    The second Law of Thermodynamics tells us that everything moves towards a state of greater entropy, but it is low entropy that enables galaxies, stars, planets and human beings. The lowest entropy state that we’re aware of in our universe was right before the Big Bang. The entirety of our own universe was condensed to a microscopic size. What caused this extreme low entropy? If it was caused by a random fluctuation in particles that implies that a great many other things are possible due to the random fluctuations of particles. One of the strangest of those possibilities is that of the Boltzmann Brain. If the Big Bang was caused by random entropic fluctuations then it is much more likely you are a Boltzmann Brain than that you are a human being.

      Not quite. Consider Liouville's constant. It is irrational and transcendental, its decimal expansion is infinite and non-repeating but it never contains any digits other than a 0 or a 1. You will never find a 2 in Liouville's constant, no matter how far you search.

    I actually considered the possibility of this when I was a child, and it terrified me, because if everything suddenly came into existence with all human memories, etc. then it is possible that everything could suddenly go out of existence in the same way... so I stopped thinking about it. But it still sometimes occurs to me. And each time it does, I am disturbed and try not to think about it... until the next time. It's a haunting idea. Literally. It haunts me.

      But I can test for that possibility too. I estimate the probability that I would form with that memory due to chance alone. It's extraordinarily small (there are many more other possible memories that don't seem a priori disfavored in any way). It's much more likely that I would form _without_ such a memory, so I reject that hypothesis using the same criterion used to falsify hypotheses in almost every scientific field.
      When the fine folks at the LHC said that they detected a new particle, "five sigma", what they mean is that a signal just as strong as the observation they made would show up due to chance with a probability of 1 in 3.5 million. That's exactly the same type of criterion that I'm using here, so Boltzmann brains are not unfalsifiable -- they're bona fide falsified, unless we're willing to treat the hypothesis differently than we do every other hypothesis in science.

    I think the problem with this idea, is that it assumes that the probability of a brain arising through evolutionary processes is low enough that it allows spontaneous boltzman brains to be more probable. There is an idea that local complex structures arise spontaneously, and will tend to increase in complexity as long as they are in a system which is far from equilibrium, and as long as this this increase in complexity leads to an increase in flux. Examples of this phenomenon include convection cells, hurricanes, whirlpools, and life itself. If we incorporate this idea, then brains are likely to arise as a byproduct of low entropy situations, where the ambient environment is far from equilibrium. It seems to me, that if this is the case, the probability of producing a brain through this process should be much higher then the possibility of one arising spontaneously arising, even if the probability of a spontaneous brain is higher than that of a spontaneous galaxy or universe.
    For a much more scientifically rigorous account of the basis behind this line of thinking, check out this paper. They do not talk about brains, but it is a very interesting look at the relationship between complexity and entropy. It also looks at open systems which are far from equilibrium, something which classical physics neglects, but which describes both ourselves and the planet on which we live. www.sciencedirect.com/science/article/pii/0895717794901880

      If you have only finite time to create brains through evolutionary processes, and infinite time to create spontaneous Boltzman brains, it's very easy to assume that there is a higher probability of the latter.
      I think you have to show that the integral of the probability with respect to time as t→∞ is finite for your argument to work, but I do like that you came up with it.

      It's not that probability of spontaneous brain is higher than the probability of a brain being created by evolution.

    The Boltzmann brain is a good reason to take the Copernican and Anthropic principles with a grain of salt because it shows there's a quality vs. quantity issue with the assumptions. Sure the Boltzmann brain may have fewer assumptions overall than continuous consciousness, but qualitatively those assumptions are far more drastic.
    Perhaps we should amend Occam's Razor. "The answer with the fewest assumptions is best" isn't exactly correct. "The answer with the lowest (Number of Assumptions * Average Assumption Extremity) is the most consistent with our current knowledge." But then you wind up with heated debates over what is and isn't an extreme assumption; we can quantify assumptions. We can't qualify assumption extremity nearly as well.

If I see a tree in X place it's there because a seed fell there, it received light from the sun, nutrients like iron were deposit from asteroids or from volcanos, this iron in turn came from supernovas and it eventually leads to the big bang but it can be tracked and it's a string of results all tied together.

      As far as our best models can tel the entire universe is fundamentally random at the most fundamental level, the locations of particles, their changes, their properties when observed, all seem to be random (Within certain limits.) We cannot prove this but then science does not seek absolute truth, only the best model.

    I've been thinking about this myself. If particles can randomly pop into and out of existence, and if time is infinite, then some time long after heat death a version of myself with all my current memories perhaps with a container of air around me will pop into existence eventually. This fucks with me because imagine what it would be like to be that version of myself. Just randomly existing in emptiness only to die soon after.

  • @jakegrist8487
    @jakegrist8487 6 ปีที่แล้ว +1

    Very good video. Thank you. My opinion is that statistical descriptions of a system are historically useful only as a means of approximately describing systems that are only approximately understood. In other words, as a more detailed understanding of anything is acquired, statistical descriptions of that system become progressively less necessary, and are superceded by more accurate math.

      That's not what a Boltzmann Brain is though. It's not a physical object flying somewhere doing stuff like in the movie.
      It's a bare brain without any sensory inputs from the reality in which it exists. It just comes into existence somewhere in the infinite space already experiencing a subjective reality, a brief moment of conscious experience. Everything that brain experiences -- its whole "reality" -- comes and goes with the brain..
