We compare Newton’s force law of universal gravitation with a corrected.simple approach based.on Bhand.ri’s recently presented.work, where the gravitation constant G is maintained. A reciprocity relation exists between both alternative gravity formulas with respect to the d.stances between mass centers. We conclud. a one-to-one mapping of the two gravitational formulas. We d.n’t need.Einstein’s construct of spacetime bend.ng by matter.
