Isn't it amazing to know, in 1 billion years the sun will become hot enough to boil our oceans thus making earth completely uninhabitable. And if that wasn't enough, our Galaxy "The Milky Way" will eventually collide with the "Andromeda" Galaxy in 4 billion years. In other wiords, humanity is doomed to dissappear no matter what unless humans somehow find a way to flee from this galaxy to another. Do you think we'll ever live The Milky Way?
