I'm confused a little bit by this and have a few questions. I wasn't sure where to put this because it's kind of a relativity question (time dilation) and a cosmology question combined. From what I understand, all galaxies are moving away from us. But isn't the Andromeda galaxy eventually going to collide with the milky way? Also from what I understand, some galaxies are moving away from us faster than the speed of light. Is that just from our point of view? Because from their point of view, we would be moving away from them at the same speed, right? But we're not really moving faster than the speed of light, or are we actually moving that fast? But if we're really moving that fast, would that cause time dilation to have an affect on us? Thanks.
