> Then what about the parallel universes hypotheses: what if the universe is constantly fragmenting into multiple futures. Actually, that's the many-worlds hypothesis of quantum theory. Parallel universes refers to something else. > This proliferation of multiple futures from any moment would tend to provide a way for doomsdays to be circumvented. Not exactly circumvented. In the many-worlds picture, all outcomes occur, including the one predicted by the Doomsday argument. > If you are cloned into N futures in this moment, and you're killed in N-1 of them, then you don't know it ... True but not compelling, because quantum theories don't require each of the many worlds to be occupied by a conscious observer. Were this not so, the universe couldn't have evolved to the point where consciousness was first possible.
