This has probably been covered here before, and it's a pretty basic question but one I've often wondered at. I read somewhere recently (and have heard it said) that we can now 'see' very distant galaxies. I forget the exact numbers but things like we are seeing galaxies that are maybe 80% as distant as the age of the universe. This is basically saying we are seeing the light that was emitted from a galaxy at some time very close to the origin of the universe. Let's say the universe is 14 billion years old and we can detect a galaxy that is 10 billion years old. If though the universe is expanding, it must mean that such a galaxy was not actually 10 billion light years away from us 10 billion years ago. Again I have no idea of numbers or the rate of expansion of the universe, but one could imagine that 10 billion years ago the point where we are and where that galaxy is were very much closer together. How come the light didn't get to us say 2 billion, 3 billion, 6 billion years ago?
