When, however, all ponderable matter is constituted as a sum of charged particles, and the force of gravity as shown is an electromagnetic phenomenon by energy exchange in the aether space between any pair of masses via a radiant flux O [erg/sec], which is proportional to the product of the two masses, we generally have with some local value of [rho] the Newtonian force between [M.sub.1] and [M.sub.2]:
