  In that situation, why would someone in a galaxy not in the center of the
universe not see all the other galaxies receding?

  (Anyways, I think that the reason why the universe must be expanding
rather than all galaxies receding from us simply because they got an
initial velocity away from the center is that in the latter case all the
galaxies would be receding from us at the same speed regardless of
distance, while in an expanding universe the farther away from us the
galaxy is, the faster its recession speed, which is what is observed.)
