The Observable Universe

The universe appears to be finite or at the very least that in the early stages of what we would call our universe, it was so dense and hot, light couldn't penetrate it. The observable universe is really the distance we can look back to which a place where the light leaving that part of the universe at a much earlier time than today couldn't pass through the universe. So in that sense, we have a very rigid access to what we can see in the universe,. therefore we call it the observable universe; there certainly could be universe beyond that.
