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. 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. Einstein's Theory of Special Relativity. General Relativity, Solar Weather, and Spiral Arms. Seems very silly that people often cite the size of Earth/human beings in relation to the universe as a measure of each human's 'insignificance'. God - Albert Einstein, Black Holes and the Collapse Of Physics As We Know it. We discovered this by looking at the white dwarf Sirius B experimentally in astrophysics (other people have done laboratory experiments). General relativity - Wikipedia, the free encyclopedia General relativity, or the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1916 and the current description of. A gravity probe whose origins date to the era before human spaceflight has finally proved general relativity right, according to NASA. Fifty years after it was conceived, a $760 million NASA spacecraft has confirmed Einstein's theory of gravity, or general relativity, physicists announced today. The great scientist made an even more profound impact on physics with his theory of general relativity, replacing Newton with a better model for gravity. Quantum Mechanics vs General Relativity. Applying Einstein's general relativity theory, the team determined that Sirius B packs 98 percent of the mass of our sun within its 7,500-mile diameter (12,000 kilometers), or within a volume slightly smaller than Earth. [B]eauty is a consequence of [general relativity and the Standard Model] being effective and approximate. Sirius B is a white dwarf orbiting the brightest star in our northern hemisphere sky, Sirius. "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). Well, that's only half of the relativity picture.
