"In 1967 Sakharov published a very interesting article titled "
Vacuum Quantum Fluctuations in Curved Space and the Theory of

important to recall that , according to Einstein , gravity is the
curvature of space caused by the presence of matter; that is by
the presence of real particles and fields ( which have some
energy density) The curvature is proportional to the energy
density , and the proportionality coefficient is Newton's
gravitational constant G, divided by the velocity of light raised
to the fourth power. Curvature ~ G/c^4 X energy density This
is the famous Einstein equation. In his work , Sakharov asserted
that this equation has a dynamic interpretation: that the
curvature multiplied by c^4/G is the change in the energy density
of the vacuum due to the curvature of space.

This sounds like the reciprocity argument regarding force
and acceleration in Newtonian terms.



Brian Whatcott Altus OK Eureka!

Brian I don't follow you point here, sorry. BTW I have Sakharov's original
1967 paper on this and I would be glad to make it available for anyone
interested.
