Is the universe computable? If so, it may be much cheaper in terms of information requirements to compute all computable universes instead of just ours. I apply basic concepts of Kolmogorov complexity theory to the set of possible universes, and chat about perceived and true randomness, life, generalization, and learning in a given universe.

Post publication note: Konrad Zuse was the first who seriously suggested the universe is being computed on a grid of computers or cellular automaton (digital physics); compare similar ideas by Ed Fredkin. They did not talk about computing all computable universes though. This paper and related ones are being discussed on the "everything" mailing list ( created by Wei Dai. Follow this link to the main page; compare messages referring to Schmidhuber's work. Pointers to more recent papers on the computable universes can be found here and here.
