Nobody ever talks about what we'll do when we collide with our neighboring galaxy, Andromeda.
Arguably that's because we're not going to do it for around another 5 billion years, but still. Early planning is key with these things people.
Don't ask me why there are mountains in this picture. Even when you can really see the 'Milky Way' from earth (I don't quite get how we're seeing it when we're in it, but that's a topic for another day) it's not that clear.
My biggest beef with our lack of planning, for this possibly earth-shattering event? Who in the name of all things sciency and stellar decided our new combined galaxy should be named Milkomeda? Did they all sit around and go 'No, Andromeda Way actually sounds cool, so we can't use that one...'
