Yes Rascal, contextually ... but I was gilding the lily.

North ... All things are expanding from each other. There is no centre of expansion. You seem to be of the opinion that a view from a particular spatial point in the Universe is unique from any other view.
Where ever you are in this Universe, you will see that Everything else is expanding away from you, and the further away, the greater the acceleration.
This is what Rascal is trying to explain. You need to delve further into the 'equivalence principle'. Hubble's observations do not mean that everything is racing away from the Earth. Everything is racing away from everything else, everywhere.
Rascals point is that this expansion, read acceleration, is being driven by the repulsive force of gravity. Einstein's interpretation of the Equivalence principle implies as much.
Gravity is indistinguishable from acceleration. This implies that gravity is NOT a 'force acting at a distance' as Newton thought but a straight line thru spacetime. We perceive it as a parabola thru space, a geodesic. There is much in Rascal's hypothesis.
Hope this helps a bit, and sorry for intruding, but my fingers got itchy reading this thread.
