## A Brief History of Gravity from Newton to the Present

**Authors:** Jose P. Koshy

We live in a 'physical universe' where bodies follow mathematical laws, and not in a 'mathematical universe'. So the concepts in physics should be inferred from observations, not from equations. Equations come only when we quantify things to verify the concepts. Newtonian gravity, though it contains some gaps, require only 'physical' bodies to explain gravity. But General Relativity and Quantum Mechanics require mathematical-artifacts inferred from equations (like 'spacetime' and 'virtual particles') to explain gravity. This seems unscientific; so let us go back to Newtonian concepts. The following assumptions can fill the gaps in Newtonian concepts, and give a clear and complete picture of gravity: (i). Motion is a fundamental property of bodies (ii). Gravity is reaction to motion
