Gravitation is the force which attracts all objects within the universe to each other [1]. In modern physics it is explained by Albert Einstein's theory of general relativity. Before general relativity, gravitation was described by Issac Newton's law of universal gravitation, which is still useful in most situations.
Gravitation is responsible for the existence of the earth and sun, without it, none of the stars or planets in the universe would exist, and life on earth would not be possible.
