They are not really the end,but that is the spacetime with no universe

It's going to take a while to reach that point. There's more mass within
the intergalactic gas between galaxies, than there is in the galaxies
themselves. If a galaxy runs out of gas, its central blackhole will stop
blowing gas away, and instead that gas will fall back into the galaxy,
restarting star formation. Or even more wildly, the intergalactic gas
will start forming new baby galaxies between the old galaxies. I figure
this stage will last a trillion years (or two orders of magnitude older
than the universe is now), with continuous cycles of gas falling into
old galaxies and/or new baby galaxies forming.
