You want to know why you see so many stars if there's so "little" in space? Because we are in a galaxy were the stars are "close" to eachother. I guess between the galaxies there's a whole lot of nothing.

By the way there isn't actually nothing between Galaxies. There is Globular Clusters which I believe get ejected in Galaxy Collisions. We have a few orbiting our Galaxy. But then again this doesn't have anything to do with what your talking about.
