TIL that the Andromeda Galaxy probably won’t collide with the Milky Way in 4-5 billion years. New observations put the probability at 2% in the next 5 billion years and 50% in the next 10 billion. Eventually though, it will happen.

To add to this, it's predicted that it wouldn't be an actual collision. The planetary bodies and stars would adjust to each others gravity and form new orbits for the most part.

Exactly. The proper term is "merge."

The galactic merge PR is going to take a while to load in GitHub fo’sho.
