Gravity Probe B: final results of a space experiment to test general relativity.
Gravity Probe B, launched 20 April 2004, is a space experiment testing two fundamental predictions of Einstein's theory of general relativity (GR), the geodetic and frame-dragging effects, by means of cryogenic gyroscopes in Earth orbit. Data collection started 28 August 2004 and ended 14 August 2005. Analysis of the data from all four gyroscopes results in a geodetic drift rate of -6601.8±18.3...

Reisenberger, et al., “A Possible Rescue of General Relativity in Di Herculis,” Astronomical Journal 97, pp. 216-221, 1989. Abstract: The binary DI Her has attracted attention because its low observed rate of apsidal advance, dw/dt = 1.0° ± 0.3°/100yr, appears to contradict general relativity, which see...
متن کاملFlat - space picture of gravity vs . General Relativity : a precision test for present ether - drift experiments
Modern ether-drift experiments in vacuum could in principle detect the tiny refractive index that, in a flat-space picture of gravity, is appropriate for an apparatus placed on the Earth’s surface. In this picture, in fact, if there were a preferred reference frame, light on the Earth would exhibit a slight anisotropy with definite quantitative differences from General Relativity. By re-analyzi...
متن کاملViewpoint Finally , results from Gravity Probe B
The great blues singer Etta James’ signature song begins, “At laaasst, my love has come along . . . .” This may have been the feeling on May 4th when NASA announced the long-awaited results of Gravity Probe B [1], which are appearing now in Physical Review Letters[2]. Over 47 years and 750 million dollars in the making, Gravity Probe B was an orbiting physics experiment, designed to test two fu...
متن کاملGeneral Relativity and Experiment *
The confrontation between Einstein’s theory of gravitation and experiment is summarized. Although all current experimental data are compatible with General Relativity, the importance of pursuing the quest for possible deviations from Einstein’s theory is emphasized. ∗To appear in the Proceedings of the XIth International Congress of Mathematical Physics (Paris,July 1994)
