How Newton Could Have Developed His Law of Gravitation.

The main idea in this paper is that physicists should have either explored the universe to discover a ‘solar system’ in which Newton’s law of gravitation applied exactly or should have explained the discrepancy between the implication of the simple Newton’s law of gravitation (circular orbits) and actual observation (non circular or ‘elliptic’) orbits, with sound logical consistency and validity. Discrepancies between a theory and actual observation should never be tolerated or given ad hoc explanations and carried forward. The discrepancy between Newton’s law of gravitation and actual observation turned out to be of fundamental importance as presented in my previous paper: “ ‘Elliptic’ Orbits and Mercury Perihelion Advance as Evidence for Absolute Motion ”
