    Yes, but not because of universal expansion really, they’re just headed in a direction that is going to intersect at some point, likely combining the two galaxies together. This’ll be so far in the future we’ll all be long dead though, on top of it being unlikely that anything is going to even come close to our solar system

        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: https://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.
