Hubble discovered that galaxies are moving away at each other at a rate, today physicists believe that this rate is increasing. I've read about galactic collisions, and that the Andromeda galaxy will eventually collide with the milkyway. If the galaxies are moving away from each other, then how is it that galaxies can collide? I can't visualize the geometry of this.
