Why dont we see all the light from stars from all the stages of the cycle.
Question asked by: fury1981
Asked on: 04 Aug 2010
Light travels at a fixed speed through a vacuum: which is the speed of light.
Therefore the further something is from us, the longer it takes that light to reach us. So the further away a galaxy is the longer it takes the light to reach us, and so when it does reach us, we see the galaxy as it was progressingly further back in time.
So a galaxy a million light years away we see as it was a million light years ago and so on.
