[QUOTE="phinds, post: 6858565, member: 310841"] I hear this over and over, but here's my confusion. If you have two galaxies, each X units of distance in diameter and separated by a distance of 10X, then after some amount of time they will each still be X units of distance in diameter but the distance between them will be 12X units of distance. How is this coordinate dependent? Is it somehow that their diameter is not coordinate dependent but the distance between them is? [/QUOTE]
