 Gravitation - Wikipedia, the free encyclopedia
In quantum gravity, the graviton is the postulated carrier of the gravitational force.
In common usage "gravity" and "gravitation" are either used interchangeably, or the distinction is sometimes made that "gravity" is specifically the attractive force of the earth, while "gravitation" is the general property of mutual attraction between bodies of matter.
Gravity was rather poorly understood until Isaac Newton formulated his law of gravitation in the 17th century.

In chemistry, gravity is the density of a fluid, particularly a fuel.
The acceleration due to the apparent "force of gravity" that "attracts" objects to the surface of the earth is not quite the same as the acceleration that is measured for a free-falling body at the surface of the earth (in a frame at rest on the surface).
Gravity is small unless at least one of the two bodies is large or one body is very dense and the other is close by, but the small gravitational interaction exerted by bodies of ordinary size can fairly easily be detected through experiments such as the Cavendish torsion bar experiment.

Einstein proposed that the four-dimensional space-time continuum is curved by the presence of matter, producing a universe in which bodies travel in geodesics that are the curved trajectories interpreted by Newton as the result of some attractive force.
Gravity is the force which Sir Isaac Newton theorized was being the cause of gravitation (or the tendency of masses to move toward each other.

 RNW: A 'relative' genius: Albert Einstein
But Einstein realized his theory was incomplete, and ploughed on until he perfected the second part of his theory, eventually revealing the force of gravity in a new light.
The new theory, called general relativity, replaces Newton's picture of gravity as a "force": now we see it as a warping of space itself, a fundamental link between geometry and the physical world.
While gravity draws matter together, a mysterious force is having the opposite effect, pushing galaxies apart.

 ScienceDaily: Putting Relativity To The Test, NASA's Gravity Probe B Experiment Is One Step Away From Revealing If ...
With general relativity, Einstein forever changed our Newtonian view of gravity as a force, postulating rather that space and time are inextricably woven into a four-dimensional fabric called spacetime, and that gravity is simply the warping and twisting of the fabric of spacetime by massive celestial bodies.
The reason is, as Caltech physicist Kip Thorne once put it: "In the realm of fl holes and the universe, the language of general relativity is spoken, and it is spoken loudly.
NASA Gravity Probe B Mission Enters Science Phase, Ready To Test Einstein's Theory (September 9, 2004) -- Gravity Probe B, a NASA spacecraft to test two predictions of Albert Einstein's general theory of relativity, achieved a major milestone last week with the completion of the first phase of its...
