The axiomatic approach is useful to see the structure of the theory from the framework of semiclassical gravity, showing the link from the mean value of the stress-energy ... In the second part, we describe three applications of stochastic gravity theory. First, we consider metric perturbations in a Minkowski spacetime.

If we find that the speed of gravity is faster than the speed of light then Einstein's theory of general relativity breaks down ... "From Einstein's theory of gravity, that is his general relativity theory, we believe mass curves space and this can cause light to follow a curved path," he told BBC News Online.

At first blush, past experiments confirming Einstein's theory of general relativity would appear to have rendered it a done deal, says Stanford University physicist Francis Everitt, lead investigator for Gravity Probe B. Yet "we don't know it all," he says.

Einstein's general theory of relativity describes gravity in terms of the geometry of both space and time. Far from a source of gravity, such as a star like ... "Even a value that differs by one part in a million from 1.0 would have major ramifications for the goal of uniting gravity theory and quantum theory,

The work appears to rule out the need to invoke dark matter or another alternative gravity theory called MOND (Modified Newtonian Dynamics). But other experts caution it has yet to pass the most crucial test - how to account for the afterglow of the big bang.
