I believe the orange-peel analogy is in place here, i.e. consider the
an expanding orange peel. The universe is just that: the peel, where the
normally included within the peel `simply' doesn't exist. Each point on the
has no special meaning with respect to others and all are equally valid
to serve as `centers'. Even more exciting is that you can end up at the same
once you've travelled along a `straight' line long enough.
Confusing? Yeah well that's cosmology...
