The discovery, reported December 16, is the best evidence yet of this effect, known as frame dragging
, around a black hole.
The analysis showed that spherical harmonics of the earth gravity field with degree l > 60 may represent a threat and their errors map significantly into LARES orbital disturbances compared to frame dragging
because for l > 60 the uncertainties in the LARES node precession get larger.
The satellite also found a "frame dragging
" effect, which was predicted by Austrian physicists Josef Lense and Hans Thirring in 1918, as a consequence of relativity.
According to general relativity, a spinning massive object drags the surrounding spacetime, an effect known as frame dragging
. A fast-spinning black hole will spin up nearby spacetime, imparting more angular momentum to material orbiting in the inner accretion disk.
In the video Titan, 2007, he staggers nude through an ink-black dungeon, his stiff frame dragging
skeletal, upright armatures decked out with neon tubing.
Confirming frame dragging
, which has been measured with great precision by only one other experiment (SN: 11/27/04, p.
There GP-B is poised to test rigorously two key predictions of general relativity: the geodetic effect and frame dragging
. The geodetic effect is a measure of how a massive object distorts the geometry of surrounding space-time, like a bowling ball on a trampoline.
Probe payoff Gravity Probe B confirms that the Earth drags spacetime as it rotates, an effect known as "frame dragging
" that is predicted by Einstein's general theory of relativity (SN: 5/21/11, p.
Pavlis (Joint Center for Earth Systems Technology, Maryland) announce the first reasonably accurate measurement of frame dragging
(also known as the Lense-Thirring effect, for the two Austrian physicists who predicted it in 1918).
Researchers had already predicted and found some evidence that rotating black holes and neutron stars stir the fabric of surrounding space and time like pancake batter, an effect known as frame dragging
(SN: 9/2/00, p.
