If there are infinite worlds, there is effectively 100% probability that an infinite number of them will be identical to this entire Earth as you see it. Pi has infinite digits. Any sequence, however long, the encoding of any documentary, can be found in the digits of Pi, and moreover, it recurs an infinite number of times. I think you are trying to avoid answering my question. Jason > An infinite number of universes does not imply an indefinite number of > copies of every particular universe.
