For once, I'm siding with the over-aged hippy. This is known as Olbers' paradox. Only an infinitely old, static universe would have uniform light intensity throughout the universe. A finite, expanding universe does not. Also, keep in mind that when a cosmologist says the universe is homogeneous they are speaking on ridiculously extremely large scales. Obviously, if you can look outside and see the Milky Way then you see that there are more stars in one spot and fewer elsewhere. So talk about homogeneous you have to go much beyond our galaxy, and our "local" cluster of galaxies to a very large distance.
