Is there a center to the universe?
If general relativity is correct, the answer is that there is no unique center to our universe anywhere within our 3-dimensional space. The center of a balloon is not located in the surface of the balloon, and the 'center' of our universe is by analogy not located in its 3-dimensional surface either. Still, every observer through out space will see the universe expand as though they are at the center of the expansion.
