It’s not just that, but it is unlikely that any star in our galaxy will collide with any star in Andromeda.

I think it’s easy to think of galaxies as individual things, like these nodes in the universe where all the stuff is stored. But galaxies are incredibly vast and incredibly empty.

I love the video this guy did on the subject: www.youtube.com/watch?v=VsRmyY3Db1Y

The part that stuck with me is that if you made the Milky Way the size of the United States, our gigantic sun holding 99.86% of the matter in the solar system would be microscopic – the size of a red blood cell. And iirc, the planet earth would be all the way down to the size of a virus.
