Give me a break. AG What about a single, infinite world in which everything is duplicated to an arbitrary level of detail, including the Earth and its inhabitants, an infinite number of times? Is the bizarreness of this idea an argument for a finite world, ending perhaps at the limit of what we can see? --stathis Papaioannou FWIW, in my view we live in huge, but finite, expanding hypersphere, meaning in any direction, if go far enough, you return to your starting position. Many cosmologists say it's flat and thus infinite; not asymptotically flat and therefore spatially finite. Measurements cannot distinguish the two possibilities. I don't buy the former since they also concede it is finite in age. A Multiverse might exist, and that would likely be infinite in space and time, with erupting BB universes, some like ours, most definitely not. Like I said, FWIW. AG OK, but is the *strangeness* of a multiverse with multiple copies of everything *in itself* an argument against it?-- Stathis PapaioannouFWIW, I don't buy the claim that an infinite multiverse implies infinite copies of everything. Has anyone proved that? AG If there are uncountable possibilities for different universes, why should there be any repetitions? I don't think infinite repetitions has been proven, and I don't believe it. AGIf a finite subset of the universe has only a finite number of configurations and the Cosmological Principle is correct, then every finite subset should repeat. It might not; for example, from a radius of 10^100 m out it might be just be vacuum forever, or Donald Trump dolls.
If there is a repetition, is it really a different universe? What happened to Leibniz's identity of indiscernibles?
