In this way, scientists are able to map the Earths

gravitational fields.

The Euclidean operator in equation (2) above has no variation with time and hence will not be sufficient for the complete description of gravitational intensity vector of time dependent

gravitational fields.

TEHRAN (FNA)- Produce and detect

gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies -- it sounds daring, but one physicist has proposed just that in a new article.

The mass of all three worlds was calculated by analysing the "tug of war" effect of their interacting

gravitational fields.

The role of homogeneous

gravitational fields in the formulation of the equivalence principle and in the foundation of Einstein's theory of gravitation is well known, say Schucking and Surowitz, but he originally treated the concepts in terms of Newtonian gravity and for small velocities.

The hope is, then, that if we can find some dark corner of the universe where general relativity fails, perhaps because the

gravitational fields it describes are so enormously strong, we might glimpse what extra ingredient is needed one that might point the way to a theory of quantum gravity.

University of Edinburgh researchers, Arwen Nicholson and Duncan Forgan's computer simulations showed that the probes could get a turbo-boost and could save fuel by doing a slingshot off the stars'

gravitational fields, Discovery News reported.

The Double Pulsar thus provides the perfect experimental set-up for tests of GR: we have two precise clocks, attached to heavy test-masses that move under the influence of strong

gravitational fields in the curved spacetime around each other.

Tidal energy exploits the natural ebb and flow of coastal tidal waters caused principally by the interaction of the

gravitational fields of the earth, moon and sun.

Scientists detected the ancient sear a decade ago after noting anomalies in the planet's magnetic and

gravitational fields in that region, says Rodger J.

A EINSTEIN'S theory was that clocks run slower within strong

gravitational fields, so a wormhole - formed when two or more massive bodies warp space - with one end close to a neutron star would enable you to step through it and emerge in the past.

He had previously argued against the laws of quantum physcis, believing the intense

gravitational fields of black holes somehow unravel the laws of quantum physics.
