It depends on where you are in the Universe. If for example at a certain point you spontaneously came into existence in the middle of certain cosmic voids. If this happened in a not so distant future. Then the edge of that void would be moving away from you at the speed of light. That would mean that light from those stars couldn't even reach you, and any light from you would never reach the edge of the void. That to me is ultimate blackness. If you want to talk about the darkest part of the Universe those may not exist yet.

An interesting side effect of the expansion of the universe is if the false vacuum collapses in one part at a certain distance that becomes isolated from the larger universe. So no matter how bad things get in one part as long as nothing is faster then light there will always be hope of some sort. May you never be born to the void.

It’s not like you’ll be able to do anything about it if it happens in YOUR part or the universe. :)

True but I still feel solace that nothing besides the heat death can destroy the entire universe. In that sense we will have left a mark of sorts. The collapse into the false vacuum might even be the start of a new universe since it would liberate so much energy. You could get Kugelblitzs forming possibly. It's hard to think what the new rules would be because so much is dependant on that one tiny thing. What I do know is the speed of light wouldn't change that much.
