Dear All,
If the image we see from a distant galaxy shows how it looked 1 billion year ago, what would that galaxy appear if we are traveling towards it at the speed of light?
Do we see the galaxy developing twice as fast? It would be great if someone could explain it with both a simple description as well as in the form of mathematics.
Thanks!
