If gravity were a "real" force, then how would I be able to tell if I'm falling or accelerating in space or on Earth?
Background:
I think it would be helpful for laypersons like myself to understand how, in practice, a "real" force differs from a pseudo-force. Virtually all explanations (eg, on this stack, ...

Can gravitational effects extend to the other fundermental forces?
It is known that gravity is not a force, but a bending of 4D spacetime. Could charge (as well as mass) have an analog in this regard? Why does mass bend spacetime but charge does not?
Sorry for the ...

Linearity of electromagnetism and gravity
If we have a very strong electromagnetic field, it stops being linear, Maxwell's equations stop working ($10^6$ Tesla or $10^9$ Newton/Coulomb);
Why can't we say the same thing for gravity? Since the ...

Is the fundamental relationship between electromagnetism & gravity unknown?
Richard Feynman made the following statement:
the relationship between the gravity forces and electrical forces
remains unknown
in the interview linked here.
In context, he made this statement ...

Numerical solution to the relative gravitational time dilation of induced dipolar gravitational fields
In gravitoelectromagnetism, an approximation to general relativity in the weak field limit, Einstein's equations simplify into a form very similar to Maxwell's equations. In this field, traditional ...

Why doesn't the force of gravitation on the earth due to the Sun change?
Since the earth moves around the sun in an elliptical orbit and the sun is located at one of the foci, hence the distance between the earth and the sun continuously changes, so why doesn't the force ...

Dark matter and gravitation
Dark matter does not interact with the electromagnetic force, however does interact with the gravitational force. Do we know if there are any big ‘clumps’ (like a star) of dark matter? If they exist (...

Possibility of the existence of Graviphotons?
I have been attempting to do research on the graviphoton yet I can find almost nothing, and many of the articles I do find are locked behind hefty paywalls. It is an interesting possibility to think ...

Silly question about a realization given by gravitomagnetism: could there exist a "apparent gravitational magnet"?
First of all, I will use a conclusion given by gravitomagnetism, but the example will concern Kerr black holes, and therefore lies in the realm of strong gravitational fields.
Well, gravitomagnetism ...

How do gravitons and photons interact?
First of all, I am a noob in physics (I‘m a computer scientist) and started reading Hawking‘s „A brief history of time“. In Chapter 6 he says that “electromagnetic force [...] interacts with ...

Why is there not a General Relativity for forces other than gravity?
I think what I'm looking for here is some sort of a bridge between the very material terms and mental images that I have access to and more of a pure math understanding. My deepest exposure to ...

Why don't ferrous metals fall to earth faster than other objects?
Given that gravity is a weak force compared with magnetism and given the fact that the earth is a magnet, why don't ferrous metals fall to earth faster than other objects? Seems like they should!
