The bonus braintwister is actually addressed in Stephen Hawking's "A Brief History of Time." The simple answer is that the universe is not static. There's also dust in the way from a lot of stars (like the ones in nebulae).
Speaking of which, if you have a chance, I highly recommend seeing "Hubble" in IMAX. A while back, they took an IMAX camera up on a shuttle flight where the astronauts were repairing the Hubble Space Telescope, so there's actual footage of space and Earth in the background. It's pretty spectacular. And they they took some of the pictures from Hubble and did something awesome with computers so it looks like you're flying into nebulae and you can see the stars inside. I was blown-away.
