Einstein's General Theory of Relativity

Einstein's General Theory of Relativity, published in 1915, revolutionized our understanding of gravity. It proposes that massive objects, like planets and stars, warp the fabric of space and time around them, much like a heavy ball placed on a rubber sheet. This curvature causes objects to move along curved paths, which we perceive as gravitational attraction. Essentially, gravity is not just a force but the result of this bending of space-time. This theory has crucial implications for how we understand the universe, influencing everything from black holes to the expansion of the cosmos.
