Gravity is a fundamental force in space, governing the movement of planets, moons, and stars. Without gravity, the universe as we know it would not exist. It keeps planets in orbit around the Sun, holds stars together in galaxies, and causes objects to fall towards each other. In space, gravity plays a crucial role in everything from the formation of black holes to the dynamics of entire galaxies.
In addition to its obvious effects on large-scale objects, gravity also affects time and space itself. Einstein’s theory of relativity shows that massive objects, like stars and planets, bend space-time, which in turn affects the movement of other objects in their vicinity.
