@MoralOfStory A short program outputs *a* possible universe w/ our phys, but specifying a *specific* universe configuration takes more bits.

@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 But for a meta-universe of 1000000 coin flips, it's easy to generate all of them, but specifying one takes 1000000 bits, yes?1 reply 0 retweets 0 likes -

@CurlOfGradient no-- while on average you can compress no more than 50%, some universes are easier; e.g. universe 0 takes very few bits.1 reply 0 retweets 0 likes -

@MoralOfStory I should have specified I mean a random string. But there are so many possibilities that would produce a uni similar to ours.1 reply 0 retweets 0 likes -

@MoralOfStory Not as many as would produce dead universes, but still an unimaginable number. So I'm 95% certain you need a lot of bits.1 reply 0 retweets 0 likes -

@CurlOfGradient order of magnitude estimate? maybe we can turn this into a bet ;)1 reply 0 retweets 0 likes -

@MoralOfStory Order of magnitude of the possible initial configurations that would produce a universe similar to our own?2 replies 0 retweets 0 likes
@MoralOfStory Considering the # of particles and using a granularity of the Planck length, an absurdly conservative estimate would be 10^80.
