Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines. See more In physics, gravity (from Latin gravitas 'weight' ) is a fundamental interaction which causes mutual attraction between all things with mass or energy . Gravity is, by far, the weakest of the four fundamental interactions, … See more Ancient world The nature and mechanism of gravity was explored by a wide range of ancient scholars.
