Andromada and the Milky Way Collide

Andromada and the milky way are part of this cluster of galaxies we call the local clus wes, sort of like a loosely bound group of clusters. They're held together by each other's gravity and a sort of swirling around each other. It's all very slow motion, and it takes billions of years for anything interesting to happen. But galaxies do collide. And if you look out there into space, we can see so many galaxies that there are lots of examples of galaxies colliding,. then settling down again into spiral galaxies.
