*** But suppose you enumerated all possible universes and ran the n'th one for n steps. Ours would be n ~ 10^120 steps, or about 400 bits. ***
Perhaps so, but on a current standard computer it would take more than 400 bits to code the universe-simulator ;) So the 400 bits figure presumes the computer decoding those bits has a fairly sophisticated general-purpose universe-simulator running on it, I'd say... Specifying the constants in the standard model only gives you an approximation of our universe in the context of a computer with a differential-equations solver or similar on it, which probably also is longer than 400 bits to code on current computer architectures... Just sayin'... I agree with your conceptual point though, so mostly I'm just nitpicking ... but also it's kind of interesting to me (as a human with some trivial and silly interests ;) whether it's 400, 4000, 400000 or 4000000 bits to really simulated our universe on a standard-issue PC with a lot of auxiliary memory...
