Scientists have tested Einstein's general relativity's predictions in weak gravitational fields
, such as those on Earth and in the solar system, but the predictions of general relativity may crumble in stronger gravitational fields
such as those of supermassive black holes.
As for the results, the research team, whose findings are published in Friday's issue of Astronomy & Astrophysics, says, "The results are perfectly in line with the theory of general relativity" and are "a major breakthrough towards better understanding the effects of intense gravitational fields
The WEP asserts that locally we cannot distinguish between inertial and gravitational fields
through 'falling body experiments'.
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.
However, the gravitational fields
between Jupiter and Saturn managed to counteract the sun's gravity and indeed pulled both planets away from the sun into their current positions.
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.
GR also predicts that gravitational fields
alter the rates of time passing at different depths of a gravitational field
