Is this an actual photo of frame dragging?
Is this new image (below) of polarized light surrounding Sagittarius A, showing actual frame dragging being captured by the magnetic field? The image is from this article If not, how would a photo ...

What angle would frame dragging shove matter in the innermost accretion disk relative to the equatorial plane or orbit?
I understand that frame dragging will imbue momentum on plasma orbiting a black hole at close range.
My first question is - is this kinetic energy inserted very narrowly relative to the equatorial ...

What will happen to the light due to frame-dragging?
Imagine a rotating black hole is blocking a cluster of stars that I'm observing. Thanks to gravitational lensing I could still see the stars albeit shifted away from their original locations. So now ...

Frame dragging in vicinity of rotating black hole
I am trying to understand subject effect in the framework of general relativity. Wikipedia says as follows:
imagine that a north–south-oriented ice skater, in orbit over the equator of a rotating

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?

What spins as a black hole? (lame question) [duplicate]
Obviously I am not a physicist.
I have seen What is black hole spin?
but this is not what puzzles me.
If I understand correctly, black hole has only three features (please correct me):
angular ...

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 ...

What distant observer would see if spaceship remains insitu just outside event horizon?
Imagine 2 spaceships found themselves just outside the event horizon of a blackhole, spaceship A tries to remain in place relative to the black hole while B accelerates around the blackhole. 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 ...

If a very massive object enters in a rotating black hole retrograde orbit should it slow down the black hole's spin?
If a very massive object is orbiting retrograde around a rotating black hole, would it slow down the black hole's spin? Of course, due to its interaction with the black hole's rotating frame, better ...

Does the twist of spacetime by a black hole increase over time?
From the Wikipedia page about Ergospheres:
As a black hole rotates, it twists spacetime in the direction of the rotation...
Does this "twisting up spacetime" add up over time in any ...

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 ...

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. ...

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 ...

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 ...
