The Theory of Relativity, developed by Albert Einstein in the early 20th century, fundamentally changed our understanding of space, time, and gravity. It consists of two parts: Special Relativity and General Relativity.

Special Relativity, introduced in 1905, posits that the laws of physics are the same for all observers, regardless of their relative motion. It introduces the concept that the speed of light is constant in a vacuum for all observers, leading to the famous equation E=mc², which shows the equivalence of mass and energy.

General Relativity, published in 1915, expands on this by describing gravity not as a force but as a curvature of spacetime caused by mass. Massive objects like planets and stars warp the fabric of spacetime, influencing the motion of other objects. This theory has profound implications, explaining phenomena such as the bending of light around massive bodies and the expansion of the universe.

Overall, the Theory of Relativity reshapes our understanding of the universe, illustrating that space and time are interconnected and that gravity is a geometric property of spacetime.
