Well
exactly. Space might even be infinite and we are always in the center of the
visible universe, since the speed of light is constant. But we couldn't see a recession speed that is a function of merely the distance of a galaxe unless space is uniformly expanding. If there was a center, recession speed would depend also on the angle between the direction of the object and the direction of the center.
