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. Newton’s theory has since been complemented by [[relativity]] to account for relativistic effects, Newtonian physics are however still valid at non-relativistic speeds. <ref>Putnam, Dr. Hilary.

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. Cambridge University Press. 1980.
