How is Gravity, assuming only General Relativity, *not* like Centrifugal Force?
It is common to state that "Gravity is not a force" due to its interpretation as a curvature effect in general relativity. By this, is it right to say that gravity is a fictitious force due ...

Earth as inertial reference frame: finite radius effects
In a recent question I tried to clarify under what conditions the Earth can be considered as an inertial reference frame. The opinions, summarized in my own answer to the cited question, are that

Is it possible to generate artificial gravity without using a centrifuge system?
I was doing research on General Relativity and Einstein's field equations and pondered on a device using that would generate artificial gravity without the use of rotational forces. I wondered since ...

What is centrifugal force relative to? [duplicate]
Edit- the answer is mach's principle and mach's principle is sketchy so there is no good answer.
So I understand that centrifugal force is really just inertia and stuff but I still have a question.

Is there "artificial gravity" created by a reference frame on a spinning object? [closed]
Believing the answer is yes, how then is spacetime curved? Will the spacetime uncurve when rotation stops? According to special relativity you can only see things from one's own reference frame. I do ...

Question on equivalence of acceleration and mass with respect to gravity
Layman’s question here. Let’s say I’m standing on the inside rim of a rotating space station spun at right rate to produce earth-like gravity. Does the spinning warp space time? If so, how can a small ...

When we spin and feel our arms fly, is it the effect of gravity?
If accelerating reference frames can be treated as normal inertial reference frames but with gravity, then for a rotating reference frame, is the centrifugal $force = gravity$ ?
More specifically, I ...
