Isaac Newton recognized that every thing (
mass) in the
universe exerts an
attraction on every other thing (mass), and he examined this attraction in detail in his theory of
gravity. Newton postulated that gravity was a universal force that affected all
matter.
Albert Einstein's work led to a major reinterpretation of the theory of gravity. Scientists now believe that gravity affects
energy as well as matter, and that it is a fundamental warping of the
fabric of
space-time. Some theorize that the force of this warping is transmitted by as-yet-unobserved particles called
gravitons.
