Is there any concensus on what the total mass of all matter in the universe is, or even whether or not there is a finite amount? I ask because the claim recently came up in discussion that recent cosmology research indicates that there is both an infinite amount of space and an infinite amount of matter in the universe. No source was cited, but the name Max Tegmark came up, associated with the claim that there is an "infinite amount of space with matter uniformly distributed throughout." I have very little knowledge of cosmology, but this immediately sets off my BS meter. Doing a search of Tegmark on the web, I can't find anything like this (but it was only a very quick search), but I did find the rather speculative and unscientific hypothesis that every entity that exists mathematically also exists physically. Any word on this guy in general and particularly the infinite space and uniform distribution of matter thing?
