Yes, in fact it may have already happened. >> That would only be true if everything that could exist does exist, and >> maybe that's the way things are but it is not obviously true. >> > > >It doesn't require that everything to exist, it requires only one > particular program to exist: the universal dovetailer.

There are a gargantuan number of ways the atoms in my 200 pound body could be organized, but there are not a infinite number, therefore if the universe is spatially infinite 10^1000 light years away (give or take a few hundred thousand million billion trillion) there can be no doubt that John Clark is typing a post to the Everything list about Boltzmann's idea.
