An accelerating universe, then, resembles a black hole in that it has an event horizon, an edge beyond which we cannot see. The current distance to our cosmic event horizon is 16 billion light-years, well within our observable range. Light emitted from galaxies that are now beyond the event horizon will never be able to reach us; the distance that currently corresponds to 16 billion light-years will expand too quickly. We will still be able to see events that took place in those galaxies before they crossed the horizon, but subsequent events will be forever beyond our view. I think this means that things we can see now are going to wink out of sight as the universe expandes and ages. We will actually see things appear to recede from us and leave us alone in the dark.
Makes me not want to stick around.

Makes me not want to stick around. We'll always have the Local Group of galaxies. Just as Rick and Elsa will always have Paris.

We might be catching up with some old tired galaxies, and they would pop into view..
Stick around...it may be fun!
