As the black hole spins, the disk's innermost material experiences a
frame-dragging effect that's about 100 trillion times as strong as the effect experienced by the Earth-orbiting gyroscopes, Ingram reported.
Renzetti [13] examined the low-altitude effects of LARES to determine their impact on the outcome of the hoped 1%
frame-dragging measurement in the LARES-LAGEOS experiment.
The second is "
frame-dragging," the twisting of spacetime near Earth caused by our planet's rotation.
The satellite carried four advanced gyroscopes to measure geodetic effect, the warping of space and time around a gravitational body, and
frame-dragging, or how much a spinning object pulls space and time with it when it turns.
Gravity Probe B (GP-B), launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and
frame-dragging, the amount a spinning object pulls space and time with it as it rotates.
of Zacatecas, Mexico) assembles papers on Process Physics and quantum foam, Carmeli's cosmology, a pseudo-Kaluza-Klein scheme for the geometrical description of the physical world, the Big Bang,
frame-dragging and gravitational wave detection, Alternative Relativistic Mechanics, equations of geodesic deviation and the inverse scattering transform, the evolution of the principle of relativity, and other topics, written by researchers in physics and mathematics from Australia, Europe, Mexico, and China.
These involve the so-called gravito-electromagnetic effects (GEM) such as
frame-dragging, or Coriolis effect, and the geodetic displacement.
An introduction to the theory includes the following sections: (1) "Spacetime, Curved Spacetime, and
Frame-Dragging"; (2) "'Seeing' Spacetime with Gyroscopes"; (3) "The Gravity Probe B Science Instrument"; and (4) "Concluding Questions of Gravity Probe B." The guide also presents seven classroom extension activities and demonstrations.
Everitt also wanted to measure the even feebler
frame-dragging effect, in which the spinning Earth should yank and twist the surrounding spacetime.
Such precessions are predicted by General Relativity (GR), and one component of this precession is the "
frame-dragging" or Lense-Thirring effect, which is caused by the rotation of the Earth.
