Actually, the universe doesn't move through space at all. All of space is the universe.

One thing that is moving through space, though, is our galaxy. There are billions of galaxies in the universe, but we haven't even begun to explore just ours. Our galaxy, the Milky Way, is estimated to be moving at about 600 km/sec, or about 1 million miles per hour, when compared to the rest of the matter we can see in the universe. Talk about fast!
