grav·i·ta·tion

(grav'i-tā'shŭn),
The force of attraction between any two bodies in the universe, varying directly as the product of their masses and inversely as the square of the distance between their centers; expressed as F = Gm1m2l -2, where G (newtonian constant of gravitation) = 6.67259 × 10-11 m3 kg-1 s-2, m1 and m2 are the masses (in kg) of the two bodies, and l is the distance separating them in meters.
[L. gravitas, weight]

gravitation

(grăv″ĭ-tā′shŭn) [L. gravitas, weight]
The force and movement tending to draw every particle of matter together, esp. the attraction of the earth for bodies at a distance from its center.

Newtonian gravity was then the only serious theory of gravity, but the flaws in theory had pushed scientists to consider if there was a better theory waiting to be discovered.
Likewise, Newton's theory of gravity tells us why Galileo's theory of gravity had met with empirical success: the large size of the earth's radius as opposed to the small size of the tower from which projectiles fall or as opposed to the small distance traveled by a canon ball are essential to the success of the predictions based on Galileo's theory of gravity as constant.
to Einstein) Your theory of gravity enables us to run the "movie" of the universe backwards.
Isaac Newton's theory of gravity is also described as being invented by Isaac Walton and is ``chiefly noticeable in the autumn when the apples are falling off the trees''.
Evolution should be considered a scientific theory in the same sense as the theory of gravity, or the theory of quantum mechanics.
Sir Isaac Newton, inventor of calculus, optics, mechanics and the theory of gravity, left the lofty halls of Cambridge University after 25 years to become the Master of the Royal Mint, a position he held for the last 30 years of his long life.
Each of these concepts can be identified with mathematical solutions to the equations of Einstein's theory of general relative -- the modern theory of gravity, in which the phenomena of gravity are explained in terms of the geometry of curved spacetime.
Einstein's theory of gravity where gravitational forces are theorized to arise from space-time curvature.
Hawking side-steps the issue: if space-time is a self-contained continuum without boundaries, as the quantum theory of gravity implies, it is meaningless to talk about what happened at or before its origin (which would be a boundary).
4), his scientific and philosophical ideas being influenced at different times by doctrines as widely divergent as Cartesian mechanics, the Neoplatonism of Mersenne, Newton's theory of gravity, Locke's sensationalist psychology and Malebranche's occasionalism.
The aim of the darkgra project is to investigate novel effects related to strong gravitational sources -such as black holes (bhs) and compact stars- that can be used to turn these objects into cosmic labs, Where matter in extreme conditions, Particle physics, And the very foundations of einstein~s theory of gravity can be put to the test.
Even if the first images are still crappy and washed out, we can already test for the first time some basic predictions of Einstein's theory of gravity in the extreme environment of a black hole," Heino Falcke, a radio astronomer from the University in Nijmegen in the Netherlands who was involved in the project, told (http://news.
