Q:
when we look at the stars there are many. Is it possible that due to light/looking at past events we are actually in some cases just looking at our own galaxy at an earlier stage and there are less stars/galaxies out there then is perceived due to this time distortion/light constant? Please email anser as well. Thankyou.

A:

In principle, you could have a universe that wraps around on itself so that looking out you could see your own history. Our own universe isn't like that, however. It's either much bigger than what we see or just plain infinite. So we can't see our old selves in the sky.
