Scientists discovered the Andromeda galaxy, known as M31, hundreds of years ago, and around a century ago, we realized that it had negative radial velocity toward the Milky Way. In other words ...

Even if the Milky Way and Andromeda don’t collide in the next 10 billion years, though, that won’t be the end of the story.
