General relativity from A to B Robert Geroch
Publisher: U.Chicago

Astronomers have obtained the most compelling evidence yet that massive objects dramatically warp space–time, as predicted by Einstein's general theory of relativity. For those unfamiliar with scientific endeavour, the goal is to develop a theory about something. 1955 ANNALS OF MATHEMATICS 62(1):128-138. "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. Note Added 05 May 2011: A new story on the BBC website, Gravity Probe B confirms Einstein effects, further discusses the work of Gravity Probe B in demonstrating the frame-dragging effect of general relativity. This theory is named general relativity . For Special Relativity, Geometry and algebra background would suffice, but for General Relativity, one needs to have a solid background in some basic partial differential equations, basic differential geometry, tensor calculus, and so on. ALGEBRAIC PROPERTIES OF THE FIELD IN THE RELATIVISTIC THEORY OF THE ASYMMETRIC FIELD. Then devise a means to test that theory by designing an. Fig b.2 - A symmetric spherical body on a two-dimensional grid that illustrates the space-time universe. 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. I am also planning to list books on Gravity, Space, Time, Black Holes, Astrophysics and Relativity, The Special and the General Theory by Albert Einsein.

Astronomers Title: A Shapiro delay detection in the binary system hosting the millisecond pulsar PSRJ1910-5959A Authors: A. [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. Melvyn Bragg on this week's In Our Time on Einstein's theory of relativity. Introduction to Relativity: For Physicists and Astronomers by John B. NASA has just announced that Einstein's theory of gravity, also known as the General Theory of Relativity, has been verified in two ways by its Gravity Probe-B (GP-B) with astonishing accuracy [1]. "in 1905 Einstein based the theory on very general principles of a philosophical character".
