Overview
Einstein's Theory of Relativity revolutionized our understanding of space, time, and gravity. It consists of two parts: Special Relativity, which deals with objects moving at constant speeds, and General Relativity, which explains gravity as the curvature of spacetime caused by mass. These theories ...
