You're not just looking up into a curtain of black. You're looking into the eye of the universe. Stare for a while and you start to realize -- on a deep, gut level -- that the moon is a giant rock circling us in space. The sun is a violent, fusion-fueled ball of plasma and gas millions of miles away that destroyed the atmospheres of all of the inner planets (including Mars, which is farther away from it than we are) and would do the same to ours if we weren't lucky enough to have a magnetic field that diverts the solar wind.
