Re: Matter/antimatter vs "regular"/"dark" matter

No, for the whole of the universe, its whole matter/energy content is relevant, irrespective of the form of the same (everything could be radiation and it might still collapse).

Models (in particular FLRW) seem to assume a uniform "gravitating gas" residing in the spacetime, and it is the expansion rate relative to the density only which determines whether the will be eventual collapse or forever expansion.
