They say the universe is expanding. They also say it all came from a single place/state. So if everything is expanding in all different directions, wouldn’t we observe some galaxies actually moving towards us as well? It just seems like if everything is expanding away from us (nothing coming towards us), then that is assuming that Earth is the center of the universe (which is wrong obviously).
In: Physics
They aren’t. The Andromeda galaxy is moving towards us and is expected to collide with the Milky Way galaxy in 4.5 billion years.
