      Not a scientist, but that kinda relies on the big bang having infinite energy, which is probably impossible. Eventually gravity will pull everything back together.

        The distances between stellar objects are far too apart for gravity to be a remote factor at all. Let alone dark energy is theorised to be the force accelerating the speed at which matter is distancing itself.

        The universe will fade out of existence as suns burn out and their heat is lost to space with even the blackholes burning out (hawking radiation) as they too disappear and space turns into the black nothingness. Objects become so far apart that not even if they emitted light you would not be able to see a thing.
