Document Summary

Gravitation is the force of attraction that exists between any two objects in the universe. Gravitation is one of the four fundamental forces of nature, along with electromagnetism, the weak nuclear force, and the strong nuclear force. Gravitation is described by the theory of general relativity, developed by albert. According to the theory of general relativity, gravitation is the result of the curvature of space-time caused by the presence of mass or energy. Gravitation is a long-range force, meaning it acts over large distances. The strength of the gravitational force between two objects depends on their masses and the distance between them. Gravitation plays a crucial role in the behavior of celestial objects, such as planets, stars, and galaxies. It is responsible for keeping planets in orbit around the sun, and for holding galaxies together. Gravitational waves are ripples in the fabric of space-time that are caused by the acceleration of massive objects.
