[QUOTE="Bradskii, post: 77390332, member: 412388"] They're not moving*. It's the space inbetween them which is expanding. To use the old balloon analogy, if you put two marks on a balloon and then blow it up, the two marks (galaxies) are in exactly the same spot on the balloon (space). But the distance between them is getting greater. *They'll definitely be moving but assume for the purpose of the exercise that they are not. They actually may be moving [I]towards[/I] each other but still getting further apart. And if you have three dots on the balloon then the two furthest apart will be moving away from reach other faster than the two losest together. So distant galaxies are receding faster than closer ones. And you get to a point when the expansion, as you pointed out, is greater than the speed of light. So they literally dissapear. Nothing happening there will ever be available to us. That distance is the radius of the observable universe - about 46 billion light years. Observable because anything outside it is unobservable.
