 Aug8 comment If the universe is infinite, shouldn't I already have been contacted by a time and space travelling doppelgänger? Well, paragraph four is just an aside, the real question is paragraph three. Aug8 comment If the universe is infinite, shouldn't I already have been contacted by a time and space travelling doppelgänger? What I mean is, if we can prove that the universe is infinite, would that not immediately disprove that near-instantaneous travel through time and space is possible? Because if it were possible, the chance of my doppelganger (or any traveller for that matter) visiting me would be 1 (since there would always be someone doing so in an infinite universe in which such travel would be possible). Aug8 comment If the universe is infinite, shouldn't I already have been contacted by a time and space travelling doppelgänger? In addition to my previous comment: en.wikipedia.org/wiki/Infinite_monkey_theorem Aug8 comment If the universe is infinite, shouldn't I already have been contacted by a time and space travelling doppelgänger? "Time travel may be a physical impossibility - an infinite universe won't change that.", I'm sorry but did you read my question? I know that and I clearly stated: "if we accept that the universe is infinite and it's possible to travel through time and space near-instantaneously" Aug8 comment If the universe is infinite, shouldn't I already have been contacted by a time and space travelling doppelgänger? "Infinite doesn't have to mean everything happens." Not everything, but if there is a remote chance, it will (i.e. a monkey typing the complete works of shakespeare by chance). Check out the doc. for the rationale behind this. Aug8 comment If the universe is infinite, shouldn't I already have been contacted by a time and space travelling doppelgänger? Well, your second set of assumptions are all covered by the first set: if the universe is infinite there will always be someone who wants to do that (if it's theoretically possible, according to the profs in the doc.).
