The General Theory of Relativity
The General Theory of Relativity, proposed by Einstein, describes gravity not as a force but as the warping of spacetime caused by mass and energy. Massive objects like stars and planets bend the fabric of spacetime around them, and this curvature guides the motion of other objects, which we perceive as gravity. Imagine a heavy ball placed on a stretched rubber sheet; the sheet dips, and smaller balls roll toward the heavy one. This theory explains phenomena such as black holes, gravitational waves, and the expansion of the universe, offering a deeper understanding of how gravity influences the cosmos.
