Theory of gravity

The theory of gravity describes the force that pulls objects toward each other. According to Einstein’s general relativity, massive objects like stars and planets bend the fabric of space and time around them. This curvature guides smaller objects to move toward the larger one, which we experience as gravity. Think of it like a heavy ball placed on a trampoline causing it to dip, and smaller balls rolling toward the dip. Gravity is what keeps planets orbit the sun, causes apples to fall, and holds us firmly on the Earth, functioning as the universe’s invisible force shaping motion and structure.
