General Relativity
Developed by Albert Einstein, General Relativity is the modern theory of gravitation, which posits that gravity is not a force but a consequence of the curvature of spacetime. In this framework, the distribution of mass and energy warps the four-dimensional fabric of spacetime, and this curvature, in turn, dictates how objects and even light move through it. As a generalization of Special Relativity and a refinement of Newton's law of universal gravitation, it accurately describes large-scale phenomena such as the orbits of planets, the bending of starlight, the existence of black holes, and the propagation of gravitational waves.
