Will an object with linear velocity in outer space experience frame dragging effects?
Will an object moving non-accelerated in outer space experience frame-dragging? It seems the mass contributions to the strdss-energy-momentum tensor are distributed spherically symmetrical, and don't ...

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 ...

How is electromagnetic induction analogous to gravitational frame dragging?
This wiki says: https://en.wikipedia.org/wiki/Frame-dragging
Qualitatively, frame-dragging can be viewed as the gravitational
analog of electromagnetic induction.
I was wondering what exactly this ...

Could quantum vacuum polarization increase GR frame dragging beyond the predicted values and therefore replace DM explanation of galactic rotation? [duplicate]
image source credits:David Butler
This anomalous speed rotation distribution of galaxies is today mainly contributed to Dark Matter.
However, since a definitive experimental measurement and ...

Equivalence Principle Frame Dragging
Why do metric equations of a rotating body (like Kerr Metric for black holes or EFE solution for rotating bodies) contain a dt dphi term, leading to rotational frame dragging effects? Please don't ...

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? ...

Does light travel same distance in same time not depending of the path orientation regarding Earth's surface?
Does light travel the same distance at the same time regardless of the path orientation? The light in the proximity of a gravitational source can bend its trajectory and frame-dragging can cause the ...

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 ...

Is it true that frame-dragging (as applied to galactic rotation curves) goes as second order in $v/c$ rather than $(GM/Rc²)(v/R)$?
I have seen various people (see e.g. comments here) dismissing this article
using the argument that GR frame-dragging is second order in $v/c$ and therefore insignificant because $v << c$ for ...

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 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 ...

What is the relative importance of the Coriolis term to the precession term in frame dragging by rotating Kerr black holes?
The Wikipedia entry for Thirring precession describes the Coriolis term as separate from the precession term. Is it fair to say that when looking at the dynamics of a rotating black hole, the ...

Does frame-dragging continuously strectch spacetime?
Frame-dragging deforms spacetime around a rotating spherical, isotropic distribution of matter (the distribution doesn't change in time). The spacetime is a little bit dragged away from the ...

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 ...
