Is there linear 'frame dragging'?
Very massive objects cause the so called 'frame dragging' that can increase the speed of a beam of light to a total aggregate speed faster than the speed of light in normal circumstances so my ...

Can somebody describe the frame dragging around Sagittarius A at the center of our galaxy?
I need to be able to visualize it, specifically the number of turns and how it relates to the horizons in the black hole and what would happen to something falling in also described. Has anyone ever ...

How do frame dragging affects a photon for outside observer?
I remember an analogy that explained this phenomenon using magnetic field, a charged particle will experience a force next to another spinning charged particle or something like that. But I don't want ...

Has frame dragging been accounted for in galactic rotation curves?
This article explicitly takes frame dragging into account in calculating expected galactic rotation curves in the absence of dark matter, and appears to obtain very close matches to observed curves. ...

Speciality of rotating black holes? [closed]
I have read that there are different properties of black hole which are rotating like, they drag the spacetime, with them. Also I read that they have kind of 'ergosphere' along with event horizon. ...

Frame dragging Warp drive [closed]
Is it possible to use frame dragging to make a warp drive?
For example: a space ship with "frame dragging generators" that constructively interfere between them to let space be dragged in ...

Can rotation be distinguished from frame-dragging?
I am trapped inside the usual elevator and experiencing a comfortable gravitational field of about 1 g. Or perhaps it's an acceleration of 1 g. I cannot tell which.
However, I notice when I drop an ...

Does the gravitomagnetic model for frame dragging imply that objects be "sped up" to rotating speed based on their inertia?
As a specific example, consider a needle on a torsionless thread lowered from deep space over a rotating planet's pole. The needle will spin at a specified rate (based on elevation, planet inertia ...

General relativity and absolute rotation
Are both centrifugal force and Coriolis force really fully explained by what is called "frame dragging" in GR? And if that is correct, does this concept "frame dragging" solve the ...

Does the gravitational distortion of a black hole depend of its rotation?
I would like to know if there is a difference produced by the added spin of a black hole to its gravitational space-time distortion.
I am considering the distortion of space-time from a point far ...

Does stellar rotation change the degree of spacetime curvature?
The Schwarzschild solution from general relativity defines the spacetime of a spherically symmetric body in a vacuum. During this derivation, the stress-energy tensor is set to zero and the solutions ...

Frame dragging affecting bending of light
If the frame dragging causes precession of an orbit does it mean that due to the rotating character of space the amount of bending of light will be added to the angular displacements of spacetime ...

Spin rotation of masses in a rotating gravitational field around a black hole
If a rotational gravitational field affects masses in the way the frame and body velocities are added together does it mean that as the rotation of the frame has a gradient of the perpendicular ...
