If one assumes that space is flat and that the Universe is approximately a sphere with mass M and the Hubble radius R then we find that we have the approximate relation:

[itex] \frac{G M }{R} = c^2 [/itex]

A mass m at the center of the sphere would have approximate gravitational potential energy

[itex] PE = - \frac{G M m}{R} = - m c^2 [/itex]

This potential energy would have a gravitational repulsion that might counteract the gravitational attraction due to mass m causing the Universal expansion to accelerate.

I would be interested to hear what you think of this line of thought.
