Do the other 3 fundamental forces also warp space-time?
I got this idea from Einstein's insight using the falling elevator. He says, that Gravity really cannot be distinguished from any other force accelerating the elevator.
A bunch of questions on here (...

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 ...

How can one fundamental force be stronger than another?
This doesn't seem to make any sense. Gravity depends on mass or spacetime curvature but the electromagnetic force depends on electric charge. For any particular particle we could say that the force of ...

Why is gravity so special?
I am not a physicist but still I love the subject very much. A thought recently popped up in my mind while studying and I'm still confused about it.
"If a person falls freely he will not feel ...

Do gravitational fields interact with electric or magnetic fields?
We know that Electric Fields interact with Magnetic Fields, but do Electric Fields or Magnetic Fields interact with Gravitational Fields, and if so how?

How is the electromagnetic/gravitational force transmitted? [duplicate]
So I was thinking about how a positive and a negative charge (or positive/positive, negative/negative) interact. I have read previously about how photons carry the electromagnetic force. However, how ...

A place of space-time where the only fundamental interaction will be the gravitational forces: does make sense?
We know that there are four (fundamental forces) fundamental interactions of nature, this Wikipedia.
I'm curious about if we can speculate that there exists a place of the space-time in which, after ...

Electric force much stronger than gravitational force? [duplicate]
It is commonly said that the electric force is much stronger than the gravitational force. Indeed, Coulomb's constant $k_e$ is much larger than the gravitational constant $G$ but they are measured in ...

Strength of gravitational waves vs. electromagnetic waves
If the recent gravitational wave's energy had reached us as visible light, how bright would it have been? Stackexchange complains about the form and brevity of the question so i add something... if it ...

How exactly are the relative strengths of gravity and electromagnetism quantified? [duplicate]
I've often heard it said that gravity is much weaker than electromagnetism, and after looking at several questions on SE, I feel that I've got at least a qualitative handle on the concept -- gravity ...

Why is gravity so weak? [duplicate]
How does physics explain the enormous disparity between the gravitational scale and the typical mass scale of the elementary particles? In other words, why is gravity so much weaker than the other ...

Gravitational force and Electromagnetic force?
I found this interesting note in one of my textbooks,
The enormous strength of the electromagnetic force compared to gravity is evident in our daily life. When we hold a book in our hand, we are ...

Interaction speed between electric charges and magnetic materials
Einstein said that the speed of a matter in universe cannot exceed the speed of light.
Is it correct for electric force transmission speed from one electric charge to other one?
What is transmission ...
