where c is speed of light, G is the gravitational constant
It is equivalent to decrease the gravitational constant
in and around the body .
where G is the gravitational constant
, c is the velocity of light, M is the Earth mass, R is a distance between a center of the Earth and a center of mass of a hydrogen atom (i.
That would change the value of the gravitational constant
in the equation relating the gravitational attraction between two masses and the distance between them.
Proposed experiments include a radio beacon orbiting the planet Mercury to detect changes in the gravitational constant
, another space-based facility to detect gravitational radiation and a test to study Einstein's general theory of relativity to an accuracy of 1 part in 1 quintillion (10.
G is the universal gravitational constant
, c is the speed of light in vacuum and M is the mass of the static homogeneous spherical mass (Schwarzschild's mass) [3, 4].
The Australians who did the original work, Frank Stacey of the University of Queensland in Brisbane and his collaborators, had found that in the mines, Newton's universal gravitational constant
appeared slightly larger than the value determined by centuries of measurement in laboratories.
1992) where the dot refers to the derivative with respect to time, G is the gravitational constant
In practice, scientists measure an effective gravitational constant
, which, in Newtonhs expression, relates the force of gravity to the masses and the distance between them.
where M is the rest mass of the Sun, G is the universal gravitational constant
and c is the speed of light in vacuum.
There has been a long history of anomalies in the measurement of Newton's gravitational constant
G, see Fig.
