Collision

(This is actually a test thing) Space is so amazing. Has anyone else heard about the Andromeda-Milky Way galaxy collision? It's a very interesting subject. It's predicted to happen (I think) 4.5 billion years from now. I'm just always so curious about what all is in the Andromeda galaxy and even what all else is in the Milky Way galaxy. Just thoughts that always pile up in my mind. Aliens, aliens, and aliens.
