I have a nagging question and hope someone is able to help.
If the boundary of the visible universe expands on a daily basis (that is the light of "new" stars will have been able to catch up with us) does that mean the night sky is brighter each night? Hope this make sense?
Also, As has been explained here problably on many times, when we see the the stars we see what they were like millions of years ago. What I dont understand is that when we look back 13 bill or so years to the start of the universe, where we not there ourselves and why are we seeing the light from such a long time ago when we would have been in the "middle" of it? Finally, how can the Inflation theory be explained as we cannot move faster than the speed of light....
Guys, I am so sorry for the many questions. The above are the ones that I suddenly think I have understood and then suddenly cannot comprehend. Hope someone can explain in simple terms.
