Is frame drag the magnetic part of gravity? [closed]
Like moving charged mass creates an magnetic field, does moving mass also creates a magnetic field associated with moving (accelerated) mass? And if so, why does the mass have to accelerate, while in ...

Frame dragging VS Mach's principle: rotating body in an empty universe
What I understand about Mach's principle VS modern physics:
According to classical physics, there are ways to distinguish weather a body is rotating or not. For example if it is rotating, the ...

Frame dragging resulting in an orbital plane?
In astrophysics today we talked about spinning black holes, ring singularities, and frame dragging. Is this also (to some degree) the cause of the milky way being as flat as it is? Does the spin of ...

Why do planetary all rings seem to be on the equatorial plane?
Why do planetary all rings seem to be on the equatorial plane?
When I first saw a picture of Uranus and its rings, I was surprised by their inclination, 90 degrees from the axis of rotation.
This ...

Does a spinning mass follow a straight trajectory in empty space? Or is it curved like a golf ball?
Suppose that we can send to identical satellites (like Voyager 1&2) on identical trajectories. But one spins to the right while the other spins to the left. Would they follow the same trajectory?...

Is there a doppler effect on the images of stars around rotating black holes?
I'm an illustrator working on a project involving rotating black holes like those discussed in "Gravitational Lensing by Spinning Black Holes in
Astrophysics, and in the Movie Interstellar" by James, ...

Does frame dragging apply to linear motion?
Firstly I will admit I do not understand the real cause of rotational frame dragging and some of the math heavy explanations are too complicated for me. To me frame dragging looks like unsubstantiated ...

Frame-dragging (conservation of angular momentum)
The frame-dragging-effect implies the rotation (in the direction of black hole angular momentum) of every object in the ergosphere. But what about the conservation of angular momentum if the object ...

Is there an absolute accelerated frame of reference?
I know from special relativity and from a little common sense that there is no absolute inertial frame of reference; that is, physics acts the same no matter what velocity you go at. However, that ...

Do two bodies spinning about the same axis in the opposite direction repel each other?
I recently read about the GEM equations, which look very much like the Maxwell's equations.
Does this mean the behavior of mass is like the the behavior of the electric charge?
So for example if you ...

How does a rotating object cause frame dragging?
Frame dragging is a consequence of general relativity.
But I don't really understand it. Of course I can find metaphors like the "honey metaphor" where stirring a honey can move the specks even if ...

Forward's frame-dragging accelerator
On 1962, Robert Forward studied the possibility of using General Relativity Frame-Dragging effects to accelerate probes inertially (that is, without feeling any internal G-forces)
One of the ideas is ...

Frame dragging around a black hole
If you have one stationary non-rotating black hole, being orbited by a 2 or more black holes just outside each other's event horizons does this alter the size of the central black hole's event horizon?...
