The idea of a "center" as stated in this article doesn't really line up with what byHisMercy thinks it means. The reason that we appear to be at the center of the universe from a visual standpoint is because the light that reaches us at this particular point in space from the edge of the universe is going to make a near perfect sphere with us at the center. However the same is true for any point in space, so the idea of being at the center is relative.
Similar with expansion, there is no true objective center of expansion, its entirely relative. Visually its explained perfectly here:
