... hundreds of billions of other such galaxies as well!

It's hard to believe that we're the only intelligent life in the universe.

Unfortunately, the distance between galaxies and even the stars within our own galaxy is IMMENSE! When Andromeda "collides" with our Milky Way in a few billion years, the probability of any two stars hitting each other is about zero despite the hundreds of billions of stars in each galaxy! The gas between the stars will rub against each other and glow, however.
