General relativity is a fundamental theory in physics that describes gravity as a curvature of spacetime caused by mass and energy. This theory revolutionized our understanding of gravitational interactions, showing that massive objects like stars and planets warp the fabric of spacetime around them, which influences the motion of other objects. This framework is essential for explaining phenomena such as black holes and gravitational collapse, demonstrating how gravity is not merely a force but a geometric property of the universe.
