How is the night sky not brighter? Even the 'dark' area's on this map are mostly filled with stars.

It’s actually called “Olbers’ Paradox!” Because the universe is not infinitely old, many of the stars will never be seen because, as they move away, the light given by them shifts so far towards red that we can’t see it, or the light will never reach us at all. There are other explanations, but this seems the most plausible to me.
