One interesting point is that if we were to one "side" of the universe, we should be able to see a difference when we look to the farthest edges of the Universe. To one direction, we should see to 5% of the age of the universe, and to the opposite, we should be able to only see to 10,20,30%, etc of the age of the universe. This is not so. We see to 5% in every direction. We could be at the very center, and the universe only slightly bigger than what we see. Otherwise, if we were not at the center, there are vast amounts of the universe that we cannot see. The more we are off center, the faster the cosmic expansion/inflation must have been. This would mean that there are vast amounts of matter out there that we cannot see, because the universe is not old enough for the light to have reached us.

hotjer, since all parts of the universe look alike, there is no way to tell where a center might be. If we could see the edge of the universe, we could calculate a geometric center and a mass center. As it is, we cannot even say if the universe is limited or infinite in size. If it is not infinite, then there is a center of mass, but we just can't detect it.
