@CurlOfGradient if you run an arbitrary universe state backwards, what are the chances it converges on a big bang?

@MoralOfStory So my proposal only works in toy universes. Good enough.1 reply 0 retweets 1 like -

@MoralOfStory Toy universes with reversible laws, unlike game of life which doesn't conserve information, to be specific.1 reply 0 retweets 1 like -

@CurlOfGradient And it takes many bits to specify such a universe, unlike our own, which probably has a low-bit count initial condition?1 reply 0 retweets 0 likes -

@MoralOfStory Unfortunately our universe has absurdly specific initial conditions.pic.twitter.com/3aK601eLTf

@CurlOfGradient Let me go on record: predicting that will turn out to be incorrect, that a relatively short program outputs our universe.1 reply 0 retweets 1 like -

@MoralOfStory A short program outputs *a* possible universe w/ our phys, but specifying a *specific* universe configuration takes more bits.1 reply 0 retweets 0 likes -

@CurlOfGradient A short program generates all possible universes w/ our phys, but I will bite the bullet harder-- our U takes few bits, too.1 reply 0 retweets 0 likes -

@MoralOfStory But considering how many possibilities there are for the initial configuration this seems trivially false?3 replies 0 retweets 0 likes
@MoralOfStory I agree that generating *all* universes takes less bits, though.
