Einstein's theory of general relativity
Einstein's theory of general relativity describes gravity not as a force between masses, but as a curvature of spacetime caused by mass and energy. Imagine spacetime as a flexible fabric; massive objects like planets and stars create dents or curves in this fabric. When other objects move nearby, they follow the curved paths, which appears as gravitational attraction. This theory explains phenomena like the orbit of planets, black holes, and the bending of light around massive objects. It revolutionized our understanding by showing that gravity results from the geometry of the universe itself, linking space, time, and matter in a dynamic, interconnected way.
