This is an interesting point of fact about what Boltzmann Brains could be.
- weregiraffe 3y agoNo it's not. Boltzmann Brains are not platonic forms. You need to conjure an entire physical world to contain a Python interpreter to run your 500 lines of code on.
- thisismyswamp 3y agoNot to mention the odds of dreaming up an entire existence out of the blue, with no base reality for training data
- criddell 3y agoI wonder how that compares to the odds of all the things that had to happen in order for you and I to exist and be here, today, thinking about this?
- thisismyswamp 3y agoA Boltzmann brain requires a similar underlying reality except with no evolution traceability for the brain's origin. Not requiring a world around the brain does not make it more likely, but less, as the probability of brains given that worlds exist multiplied by the probability of worlds is still much higher than the probability of brains regardless of the existence of worlds
- criddell 3y agoYou can’t even be certain that you aren’t a Boltzmann brain. If you could prove it (either way), it would be a publishable paper and could probably be the basis of a PhD for yourself.
- weregiraffe 3y agoBoltzmann brain is just one of the theoretically infinite combinations of matter that can be randomly conjured out of the quantum chaos (with a very low probability). Our entire visible universe could be a "Boltzmann Universe", and we'd have no way of knowing it.
- criddell 3y agoIf the Wikipedia page on Boltzmann brain is accurate, then the probability is surprisingly (but relatively) high. > The Boltzmann brain gained new relevance around 2002, when some cosmologists started to become concerned that, in many theories about the universe, human brains are vastly more likely to arise from random fluctuations; this leads to the conclusion that, statistically, humans are likely to be wrong about their memories of the past and in fact be Boltzmann brains. When applied to more recent theories about the multiverse, Boltzmann brain arguments are part of the unsolved measure problem of cosmology.
- ben_w 3y agoKinda, I guess? Boltzmann brains are likely to be wrong about all of their beliefs owning to them being created by an endless sequence of random dice rolls that eventually makes atoms that can think, so it's fine if they are silicon chips that think they're wet organic bodies (amongst other things). A computer with say 2^((175e9)*8) parameters is simpler than a human brain, so more likely to be produced by this process. But the 500 line file is a red herring.
- ganzuul 3y agoI mean to say that since so few bits are required to encode perception, the universe in which Boltzmann Brains exist in is teeming with intelligence. Poetically, an intelligent universe seems closer to reality thanks to this new observation.
- ben_w 3y agoVastly and incomprehensibly closer to reality while still a rounding error from zero because the initial number was just that small.
