Is there a known formula of the speed distribution of distinct layers in the frame-dragging region of a BH?
I am asking this question only because I want to figure out does space move in this case similarly to a fluid like water or oil are or even more better as speeds o planets around a star.. or this ...

Speed of light affected by gravity or frame dragging effect
If we do not really 100% know how light works as a oscillation we also do not know is its speed indeed constant no matter is there a space or space-time motion that can affect it. Could a device that ...

Does Mach's principle imply that the gravitational field has a non-zero curl?
I would normally visualize the gravitational field as "radial", i.e., one whose curl is zero. However, while thinking about Mach's principle, particularly the notion of frame-dragging (as ...

Is frame dragging accelerating asteroids or cometes that after passing fairly close to the gravitational source move away?
What is interesting but also confusing for me,if this is true, is that if frame dragging somehow gives a'kick' to a highly elliptical orbiting object it seems that this object cannot orbit for so long ...

Will the trajectory of a body moving straight towards a rotating BH differ if space just rotates around or if space spiralls into the BH?
Will the trajectory of a body moving straight towards a rotating BH differ if space just rotates around or if space spiralls into the BH? Can this difference be clearly measured? Also as a very dense ...

Are rotating black holes producing a frame dragging effect inside the event horizon?
Are rotating black holes producing a frame dragging effect inside the event horizon? Is that effect moving space inside the event horizon at speeds far greater than the speed of light?

Would our orbit really remain the same if the sun were a black hole of equal mass?
There seems to be an idea floating around that the sun could be replaced by anything of equal mass with no consequence to our orbit.
It seems to me that if the mass of the sun were confined to a ...

Is there a possibility of frame dragging inside the event horizon?
Is there a possibility of frame dragging inside the event horizon? If frame dragging is related with gravity and space and as the black hole fills a space and produces a gravitational effect that ...

Does Earth's rotation affect the orbital velocity of its satellites?
We all know about the spin of black holes. That spin and of course it's gravity determines the minimum distance a star can orbit the black hole with a min orbital velocity.
Do we see similar result? ...

Can the curvature of space-time be also described as a 'frame' (space) whirlpool?
Can the curvature of space-time be also described as a 'frame' (space) wirlpool?
When we talk about the Schwarzschild metric it can be immagined as a curved manifold but in the Kerr metric it seams ...

The Sun bends planets' trajectory and speeds up it towards the perihelion; does it both actions with light? [duplicate]
The Sun bends planet's trajectory and speeds up it towards the perihelion; does it both actions with light? If it speeds up light too, then does it mean that gravity is a consequence of a vortex that ...

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 ...

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 ...
