From here: http://math.ucr.edu/home/baez/physics/Relativity/GR/centre.html -------------- The balloon analogy is very good but needs to be understood properly—otherwise it can cause more confusion. As Hoyle said, "There are several important respects in which it is definitely misleading." It is important to appreciate that three-dimensional space is to be compared with the two-dimensional surface of the balloon. The surface is homogeneous with no point that should be picked out as the centre. The centre of the balloon itself is not on the surface, and should not be thought of as the centre of the universe. -------------- It was weird to envision the balloon as the universe, it tripped me up for a while. But when you think of only the surface of the balloon as the universe, it's a little easier.

If the universe originated in the 'Big Bang', that is, expanding more or less uniformly from a single point wouldn't that point be the center?
