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 ...

How similarly are light and matter affected by gravity?
For a path of travel in a shape that is straight before it curves, if the curvature of the path is attributable to gravitational force, what additional information (if any) would be capable of ...

Interpreting a solution of the Einstein equations for a given matter content
I've been always confused with the way people interpret solutions of Einstein equations for some given source.
Here's an example:
Given some particular solution $(g,F)$ of the Einstein-Maxwell ...

When we say gravity "bends" spacetime, does it also "bend" other fields (such as EM)?
Do other fields remain unaffected by gravity and only the spacetime field gets curved? Or does gravity bend other fields too? What is the way to prove that other fields don't get bent?

Why doesn't electricity and magnetism distort space as well? [duplicate]
I think Kaluza/Klein was partly worked on to find additional dimensions to account for electric and magnetic fields.
I am confused why the gravity field gets the privileged spot of distorting space-...

Gravity and the Speed of Light
Let's assume that I am on an airplane that is at about 4,000 altitude and now let's also assume that I am standing on one of the wings with a light torch, if I point the light torch below to the ...

If gravity is a bend in Space-time then what is magnetism?
Einstein postulated that gravity bends the geometry of space-time then what does magnetism do in to the geometry of space-time, or is there even a correlation between space-time geometry and magnetism?...
