    "abstract": "Recent developments in cosmology indicate that every history having a nonzero\nprobability is realized in infinitely many distinct regions of spacetime. Thus,\nit appears that the universe contains infinitely many civilizations exactly\nlike our own, as well as infinitely many civilizations that differ from our own\nin any way permitted by physical laws. We explore the implications of this\nconclusion for ethical theory and for the doomsday argument. In the infinite\nuniverse, we find that the doomsday argument applies only to effects which\nchange the average lifetime of all civilizations, and not those which affect\nour civilization alone.",
