Of course general relativity is really about semi-Riemannian geometry [though physicists like to refer to it as merely 'Riemannian'], so you would want to also refer to texts like O'Neill's Semi-Riemannian Geometry With Applications to Relativity. Fig b.2 - A symmetric spherical body on a two-dimensional grid that illustrates the space-time universe. "General Relativity from A to B" explained to me the meaning of the radar-coordinates (emphasizing operational measurements) and the meaning of the spacetime interval (emphasizing the causal structure). Fifty years after it was conceived, a $760 million NASA spacecraft has confirmed Einstein's theory of gravity, or general relativity, physicists announced today. Hartle's book Gravity: An Introduction to Einstein's General Relativity, chapter 6, problem 9. [B]eauty is a consequence of [general relativity and the Standard Model] being effective and approximate. Shapiro time delays are one of the four tests of general relativity possible in the solar system. This problem is actually one assigned in the undergraduate general relativity course I took in the spring 2008. IT TOOK FIVE DECADES from conception to results, but finally NASA's Gravity Probe B has confirmed two cherished predictions of Einstein's General Theory of Relativity. According to Einstein, the Earth's gravity warps spacetime like a bowling ball on a trampoline. This theory is named general relativity . Astronomers Title: A Shapiro delay detection in the binary system hosting the millisecond pulsar PSRJ1910-5959A Authors: A. Astronomers have obtained the most compelling evidence yet that massive objects dramatically warp space–time, as predicted by Einstein's general theory of relativity. Despite this setback, in 2007 the Gravity Probe B team confirmed one prediction of general relativity. "The space-time around Earth appears to be distorted just as general relativity predicts," says Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission.
