In an infinite universe, the speed-of-light limit is not a problem. Surely it limits the speed of computing but any computation can be performed eventually.
Does this hold in a universe that is also expanding (like ours)? Such a scenario makes the ‘infinite’ property largely moot given that any point within has an ‘observable universe’ that is not infinite. That would seem to rule out computations of anything more complicated than what can be represented within the Hubble volume.
Yes, this was exactly my point regarding the universe being asymptotically de Sitter. The problem is that the universe is not merely expanding, it’s expanding with acceleration. But there are possible solutions to this like escaping to an asymptotic region with a non-positive cosmological constant via false vacuum collapse.
