General Relativity

About

General Relativity, introduced by Albert Einstein in 1915, revolutionized our understanding of gravity and spacetime. It posits that gravity is not a force but a curvature of spacetime caused by mass and energy. According to this theory, objects move along geodesics, which are the shortest paths possible in curved spacetime. This concept unified the laws of physics under a single framework, incorporating both space and time as a four-dimensional spacetime continuum. Key predictions of General Relativity include gravitational time dilation, gravitational lensing, and the precession of orbits. These phenomena have been experimentally confirmed, solidifying General Relativity as a cornerstone of modern physics. It has led to significant advancements in astrophysics and cosmology, explaining phenomena like black holes and the expansion of the universe. General Relativity's impact extends beyond physics, influencing philosophical and mathematical perspectives on space and time.
