Im sorry if im mising the plot completely here....

 

If the universe started at the big bang (or something similar) and then expaned from there, and we know within reasonable doubt how old the universe is then can we not say that the universe is no bigger than light could have traveled during that time (since nothing can move faster than light) ????

 

Maby im mising something...

 

Thanx

The big bang happened everywhere. There is no single point from which the universe is expanding, it is all expanding away from everything else. There is also no limit to the expansion of space... it is free to expand faster than the speed of light.
