Newton developed the [[Theory of Universal Gravitation]], more commonly known as gravity, when, according to  legend, a falling apple struck him on the head. He realized that the same force that pulled the apple to the ground could be what keeps [[Jupiter]]'s moons in orbit. His theory stated that all matter is attracted to matter by a force, whose strength increases proportionally to the mass of the objects involved, and inverse proportionately to the distance between them. The theory's accuracy was later improved by the theory of [[relativity]].

His theory stated that all matter is attracted to matter by a force, whose strength increases proportionally to the mass of the objects involved, and inverse proportionately to the distance between them. Newton’s theory has since been falsified, replaced by [[relativity]], and it is no longer scientifically valid. <ref>Putnam, Dr. Hilary. Mathematics, Matter, and Method.
