Le Sage 's theory of gravitation is a kinetic theory of gravity originally proposed by Nicolas Fatio de Duillier in 1690 and later by Georges-Louis Le Sage in 1748 .. gravity. gravity. Nicolas Fatio de Duillier. Nicolas Fatio de Duillier. Georges-Louis Le Sage. Georges-Louis Le Sage. The theory proposed a mechanical explanation for Newton 's gravitational force in terms of streams of tiny unseen particles -LRB- which Le Sage called ultra-mundane corpuscles -RRB- impacting all material objects from all directions .. According to this model , any two material bodies partially shield each other from the impinging corpuscles , resulting in a net imbalance in the pressure exerted by the impact of corpuscles on the bodies , tending to drive the bodies together .. This mechanical explanation for gravity never gained widespread acceptance , although it continued to be studied occasionally by physicists until the beginning of the 20th century , by which time it was generally considered to be conclusively discredited .. gravity. gravity
