Gravitational Theory explains the force of gravity, which is the attraction between objects with mass. This theory, primarily formulated by Isaac Newton and later expanded by Albert Einstein, describes how massive bodies like planets and stars influence the motion of other objects in the universe. At its core, Gravitational Theory helps us understand phenomena such as the orbits of planets, the behavior of galaxies, and the bending of light around massive objects. It is fundamental to our understanding of the universe and plays a crucial role in fields like cosmology and space exploration.
