I’ve taken this out of context, but you have made similar statements before, Jacques. I’m not sure if you mean this literally, or as an analogy that makes a convenient way to think for most purposes. It is certainly a convenient analogy. However, I see one way in which the predictions of the MWI of a closed universe would be different from the predictions of a one world interpretation in an infinite universe. Basically, when the observers within the closed universe became able to observe the closed nature of their universe, they would have a difference between the MWI of their own universe and a one world interpretation of some part of an infinite universe, because the topologies must differ. Now, as is frequently argued here, nothing is impossible for a QM universe, so there would actually be some incredibly tiny measure of universe segments in an infinite universe where just by chance, over billions of years, the universe segments acted in a manner probable for a closed topology. But what is left of the simple statement above is that the measure of a closed appearing universe would be *very* much smaller in an infinite universe than in a closed universe. Gale
