Has finally proved general relativity right, according to NASA. 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. The rotation of the Earth affects the movement of spacetime itself. A gravity probe whose origins date to the era before human spaceflight has finally proved general relativity right, according to NASA. 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. 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. This theory is named general relativity . The aim of this groundbreaking new book is to bring general relativity into the undergraduate curriculum and make this fundamental theory accessible to all physics majors. 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. If gravity did not affect space and time, Gravity Probe B's gyroscopes would point in the same direction forever while in orbit. Hartle provides a fluent and accessible introduction that uses a minimum of new mathematics and is illustrated with a wealth of exciting applications. The discovery of the double radio pulsar system, PSR J0737-3039A/B, surpassed most expectations, both theoretical and observational, as a tool to probe general relativity, stellar evolution and pulsar theories. Fig b.2 - A symmetric spherical body on a two-dimensional grid that illustrates the space-time universe. Then devise a means to test that theory by designing an. Finite-dimensional vector spaces. 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. For those unfamiliar with scientific endeavour, the goal is to develop a theory about something. B) General Theory of Relativity. - General relativity from A to B.djvu 1.35 MB Haag R. There are many news article on the latest report from Gravity Probe B stating how the results are consistent with predictions from Einstein's General Relativity (see here, here, and here).
