How do we account for the 'one way' drag of moving space?
As I understand it, the rotating space outside a Kerr black hole drags radially falling particles into circular motion. Similarly the river model posits that the inward flow of space ensures particles ...

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 ...

Do frame dragging affects falling object?
Imagine there is a tall tower erected at the equator, a pulse of light is beamed from the top of the tower to the ground. Do I need to consider frame dragging? After all the spacetime is being tucked ...

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 ...

Can linear frame dragging cause gravitational dipole radiation?
I have just learned that linear frame dragging exists in General Relativity. I have also seen simulations where a periodically accelerated and decelerated mass causes a sort of gravitational dipole ...

Space mission for experimental verification of frame-dragging in the strong-gravity limit
Frame-dragging is an important general relativistic effect that has been observed in the weak-field limit by the Gravity Probe B experiment for the gravitational field of the Earth.
Although the ...

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 ...

Thirring-Lens 1918 Paper seems to be wrong in the numeric results. Am I misreading it?
The 1918 paper that is often considered a basis for frame dragging (a copy is at http://www.neo-classical-physics.info/uploads/3/4/3/6/34363841/lense_thirring_-_lense-thirring_effect.pdf) seems to say ...

Do stationary objects (constant distance and angle to central body) experience frame dragging?
Imagine there is a test mass in the vicinity of spinning black hole, but the test mass is kept in place, i.e. it is not in free fall or orbit. Does it experience frame dragging?
My guess would be 'no',...

Will two passing bricks in empty space induce rotation in one another?
Two identical rectangular bricks with mass $m$ pass each other anti-parallel in empty space with a constant velocity $v$. Say the smallest distance between them is $s$. Assume the bricks to be aligned ...

Do irreducible off-diagonal components in the stress-energy-momentum tensor cause framedragging effects?
Let's take a look at the stress-energy-momentum tensor:
We can distinguish various components.
The 00 component represents the mass-energy density as seen in a local frame moving along with the ...

If I make the entire universe rotate, will the bucket appear to be rotating?
Newton's bucket experiment is a way to tell if you are in a rotating frame. If you have a bucket of water which is spinning the water surface will form a concave shape. Likewise, if the bucket is not ...

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 ...

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 ...

How do I reconcile (what I see as) an apparent difference in the frame dragging formula used for Gravity Probe-B versus Lageos?
The frame dragging impact above the north pole is given at NASA's Gravity Probe-B website as:
$$\Omega = \frac{GI\omega}{c^2r^3}.$$
That is, when the satellite is above the pole, it rotates with the ...
