yes _________ We don't know yet. There are several competing theories about the distant future of the universe, and our galaxy.

First off, our galaxy is going to collide with the Andromeda galaxy in about 5 billion years to so. Since galaxies are mostly so much empty space, we don't expect things to actually hit each other, although I'm sure that a few stars will actually collide. Good thing we're probably not going to be around to see it happen.

Farther off in the future, we do not know if the cosmic expansion will continue, or will eventually slow down and collapse. There does not currently appear to be enough mass in the universe to stop the galactic expansion. If there is not, then about 200 billion years in the future, the universe will expand into a cold, dark infinite night.
