gravitational field

(mechanics)
The field in a region in space in which a test particle would experience a gravitational force; quantitatively, the gravitational force per unit mass on the particle at a particular point.

There is a lingering conundrum, if the time-space fabric extends only up to the extension of the gravitational field there can be no vacuum beyond the edges.
At the semiclassical level an interesting event in which the CEP is also supposed to be violated but not the WEP is the tree-level deflection of different quantum particles by an external weak higher-order gravitational field. We recall beforehand that in Einstein theory the scattering of any particle by an external weak gravitational field is nondispersive which, of course, is in agreement with the WEP.
Therefore, the effect of scalar field on light (or the space polarization) should be much more easily detected than the effect of scalar field on weight (or the gravitational field shielding).
The theory also predicted that light rays will be bent by strong gravitational fields. In 1919 the British astronomer Arthur Eddington confirmed that idea by making careful observations of the positions of stars whose light passes close to the sun during a total solar eclipse.
"The wound up gravitational field eventually stops and unravels which sends the planet off in an opposite spin.
To put it crudely, we are all scattered bits of an imagined integral paradise that came too close to the real world and was shattered by it, leaving us to spin forever in its baleful gravitational field. At best, we can take our bearings, remember (while memory lasts) our earlier positions, and compare-contrast them--by writing the sorts of books that Sebald wound up writing.
Experiments with this systems are interesting because the system operates inside the gravitational field of the earth, and the total mechanical energy, potential system may consist of three different forms of energy, namely gravitational potential energy, potential energy stored in the spring, and kinetic energy.
The effect of the two classical singularities (/ pseudo-singularities) of the Schwarzschild solution on the quantum wave function for the gravitational field is studied using a wave function initially localized on the classical solution.
"The star was being yanked around by the gravitational field of not one, not two, but three planets!"
The only way to figure his popularity is there's an undiscovered element of physics where people's opinions are being sucked into his gravitational field. I don't know which twisted path this country tripped down, but it must have taken a header into a sharp stone wall to take Rush seriously and start thinking the poor and helpless are the enemy.
Einstein had predicted that light rising against a gravitational field would lose energy so that it would redden slightly (see 1916).
