History of gravitational theory

Common card · No. 350869

In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times. The first extant sources discussing such theories are found in ancient Greek philosophy. This work was furthered through the Middle Ages by Indian, Islamic, and European scientists, before gaining great strides during the Renaissance and Scientific Revolution—culminating in the formulation of Newton's law of gravity. This was superseded by Albert Einstein's theory of relativity in the early 20th century. Greek philosopher Aristotle (fl. 4th century BC) found that objects immersed in a medium tend to fall at speeds proportional to their weight. Vitruvius (fl. 1st century BC) understood that objects fall based on their specific gravity. In the 6th century AD, Byzantine Alexandrian scholar John Philoponus modified the Aristotelian concept of gravity with the theory of impetus. In the 7th century, Indian astronomer...
