The Gravity Probe-B measured the geodetic effect, the amount that Earth warps the space and time in which it sits, and frame-dragging, or the extent that Earth's rotation churns spacetime around with it. A gravity probe whose origins date to the era before human spaceflight has finally proved general relativity right, according to NASA. If time travel is possible, then it is possible for you to kill your father before you were born. The rotation of the Earth affects the movement of spacetime itself. If B-theory is true and special and general relativity are true, then time travel is possible. Einstein Passes Strictest Test: NASA's Gravity Probe-B Proves General Theory of Relativity Correct. B) General Theory of Relativity. Geroch in General Relativity from A to B (1978): One might very well be left with the impression that the theory (of general relativity) itself is rather hollow.: What are the postulates of the theory? This problem is actually one assigned in the undergraduate general relativity course I took in the spring 2008. Hartle's book Gravity: An Introduction to Einstein's General Relativity, chapter 6, problem 9. GENERAL Relativity), (b) specifically the gravitational field of a rotating massive body [which is more complicated to work out than the field of a non-rotating body], and (c) objects moving in circular orbits around such a body. By Debjyoti Bardhan on May 5th, 2011. 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. For the record, I teach a one-semester course in General Relativity for advanced graduate students every two or three years. Has finally proved general relativity right, according to NASA. I also teach Special Relativity at the This experiment involves (a) gravitational effects (i.e. However, we are still testing out all its predictions. "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). It is the culmination of a five-decade old project. €�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.
