Who developed the Theory of Relativity?

The Theory of Relativity was developed by Albert Einstein in the early 20th century. This groundbreaking theory comprises two parts: the special theory of relativity, introduced in 1905, and the general theory of relativity, presented in 1915. The special theory introduced the concept that the laws of physics are the same for all observers, regardless of their relative motion, and highlighted the relationship between space and time, culminating in the famous equation E=mc². The general theory of relativity expanded upon these ideas to incorporate gravity, proposing that massive objects cause a curvature in spacetime, which is experienced as gravity. This fundamentally changed our understanding of physics and the universe, establishing Einstein as one of the most significant scientists in history.
