Einstein's theory of gravity
Einstein's Theory of Gravity, known as General Relativity, describes gravity not as a force, but as the curvature of space and time caused by massive objects. Imagine placing a heavy ball on a stretched rubber sheet; the sheet sinks around the ball, creating a curve. This curvature tells other objects how to move. For instance, Earth orbits the Sun not because it is "pulled" by it, but because the Sun's mass curves space around it, guiding Earth's path. This theory revolutionized our understanding of gravity, explaining phenomena like black holes and the bending of light around massive objects.

Einstein's theory of gravity, known as General Relativity, proposes that gravity is not a force but a curvature of spacetime caused by mass. Imagine placing a heavy object on a rubber sheet; it creates a dip, causing smaller objects to roll towards it. In this way, massive bodies like planets and stars warp the fabric of spacetime, influencing the movement of other objects nearby. This explains why planets orbit the sun and why light bends around massive objects, leading to phenomena such as gravitational lensing. Overall, gravity is a result of how mass interacts with spacetime.
