[QUOTE="Mark Quayle, post: 77200061, member: 410020"] Yeah, I understood distances, but, for eg, it doesn't make sense to me how, if, let's say, "east" of us a galaxy is receding (relative to us) at, let's say, 1/4 the speed of light, and "west" of us, another is receding relative to us at 1/4 the speed of light, how an observer in the one galaxy would see the other galaxy with the same degree of redshift that we do. But maybe that isn't what you were saying. I do see how very distant galaxies might seem about the same for any Milky Way observer, or maybe even any observer in our local galaxy cluster. The two galaxies, supposing each to be receding relative to us, at 3/4 the speed of light, should be, according to intuition, be receding relative to each other, at more than the speed of light. But people keep telling me it is impossible to exceed the speed of light. I keep wanting to ask them, "The speed of light relative to WHAT?" THAT, I still do not understand. [/QUOTE]
