In a certain future we would see nothing more except the stars of the local groups of galaxies, where the gravity still prevails. From this point of view we live in a phase of numerous information which will remain in darkness later, forever. Ok, not in our lifetime.


That's quite correct Heinz. I ofter hear the objection that faster than light travel is impossible so how can the Universe be expanding faster than light? Because it's the fabric of the Universe expanding. Within the Universe nothing can travel faster than light except the expansion of space-time itself. Mind expanding stuff - if you'll pardon the pun.

It's mind boggling to think of the future rise of some intelligent species in the Universe when all celestial objects have receded immense distances from each other. They will live in a dark Universe - never becoming aware of the stars. They will believe there is nothing. We are fortunate to be born in the years of light.
