Dear List Members:
In classical Newtonian gravity theory, the force of gravity falls
off as the inverse square of distance. However in General relativity this is
very slightly modified to an inverse 2+& where & is a very small value. Does
anyone have any information on the value of &. Also does anyone believe that
this small deviation can be related to the fact that the hypothetical
exchange boson, the graviton, is also subject to the force it mediates. Any
references on this would be helpful.
