Sorry if this is in the wrong place. Happy for it to be moved. I've heard it said that a multiverse containing an infinite number of universes, would lead to the ridiculous. The argument is something like this: 1) An infinite number of universes contain an infinite amount of matter. 2) Conceptually, you could keep exploring the multiverse until you encountered something silly like a universe where a chocolate tea pot orbits pluto. 3) Because the multiverse is infinite then this place exists somewhere (like spinning a dice until it lands on 6). This seems wrong to me. Even if the multiverse contains an infinite set of universes, the set of conceivable universes must also be infinite? My set theory isn't that good, but surely two infinite sets can still overlap rather than contain each other? I'd like to understand this a little better and I think you guys might be better placed to think it out.
