General relativity from A to B Robert Geroch

The process of temporal becoming in my own consciousness smacks against the claims of B-theorists. 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. In particular, white dwarfs — like Sirius B, illustrated above — condense a Sun's worth of mass into a volume of only the Earth, creating spacetime that's curved 100 times more severely than at our Sun's photosphere. A) 1903 b) 1900 c) 1905 d) 1904. If gravity did not affect space and time, Gravity Probe B's gyroscopes would point in the same direction forever while in orbit. A) 1923 b) 1915 c) 1918 d) 1924. Hartle's book Gravity: An Introduction to Einstein's General Relativity, chapter 6, problem 9. Well, they want to make an atom interferometer to measure the effects of general relativity, by starting with ultra-cold rubidium atoms and manipulating them with light pulses. When did Albert Einstein complete his general theory of 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. This problem is actually one assigned in the undergraduate general relativity course I took in the spring 2008. General relativity is said to have reintroduced absolute simultaneity into physics. Gravity Probe - B Instrument and Data Reduction. Astronomers have obtained the most compelling evidence yet that massive objects dramatically warp space–time, as predicted by Einstein's general theory of relativity. Who recommended that Albert Einstein be kept out of USA by Alien Exclusion Act? One of the most spectacular and successful ideas of the 20 Century was Einstein's General Relativity, or the idea that matter and energy determines the curvature of spacetime, and the curvature of spacetime in turn determines how gravitation works. Gravity Probe - B and General Relativity. The main purpose of this experiment was to test the truth of the premise of the main fields of space and time that Einstein proposed as the basis of the theory of general relativity.
