/* Gravity */
== Gravity ==
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 inversely proportional to the squared distance between them. Newton's theory is based on action-at-a-distance which has always been opposed by some scientists, and now most physicists endorse the very different [[theory of relativity]]. Both theories predict identical results at small scales, similar results
a the scale of the [[solar system]] and very different results at cosmological scales beyond the [[solar system]].
