One of the sad possible outcomes of this is also that future people won't have the proof most need to believe in a universe out there: If you can't see it, how can you believe in it? No the entire universe is this big ball of stars we all live in... which also makes me wonder what will become of the Local Group if we merge: Each contains a supermassive black hole at its heart. I'm thinking that most life will be snuffed out during that period.

And then the long darkness.
