The inflationary model of the universe explains that any point in the universe is as valid a center as any other. We cannot point our telescopes one way and see fewer galaxies than we do in the opposite direction.

We tend to think of it as a big firecracker. But there is always a speck of something on the outside of a firecracker that moves the most, and it can look back and see most of the rest of the explosion.
