Theory of Relativity

The Theory of Relativity, developed by <a href="/article/albert-einstein">Albert Einstein</a>, fundamentally changed our understanding of space, time, gravity, and the universe. It consists of two main parts: special relativity, which deals with motion in the absence of gravity, and general relativity, which describes gravity as the curvature of spacetime caused by mass and energy. This theory has been confirmed by countless experiments and observations, leading to groundbreaking discoveries and technologies.
