EM AND GRAVITY

This thread is about the relationship between electromagnetism and gravity.  (first, a small description of electromagnetism and gravity would be enjoyable.) second, how would one define that relationship?  does EM react to gravity, or gravity react to EM? or is it both?  would it theoretically be possible to use a for of "coil" to produce a gravitational force?  how would one go about doing that?  to be brief, any information about this would be very appreciated.

LIGHT BENDS AROUND PLANETS QED

wow.  i am in awe at the wealth of knowledge you have given me.

come on, doesn't anyone know a bit in this matter?

WELL MAYBE THEY'LL SAY SOMETHING AFTER YOU GIVE A SMALL DESCRIPTION OF ELECTROMAGNETISM AND GRAVITY BECAUSE NO ONE ELSE GIVES ENOUGH OF A SHIT TO RESEARCH THINGS FOR YOU

"would it theoretically be possible to use a for of "coil" to produce a gravitational force?  how would one go about doing that?"

Yes. Just make it a very massive coil.

"does EM react to gravity, or gravity react to EM? or is it both?"

Neither. Inertial movement follows geodesics in space-time.

You are forgetting that light exists as both, a particle, and as a wave within the electromagnetic spectrum. As our physics guru >>2 pointed out, gravity can effect light. Thus, gravity is capable of interacting with electromagnetic forces, in a sense.

OP, if you are trying to unravel the mysteries of the universe without actually knowing anything about the subject, and artificially create gravity using... a coil, you are wasting your time.

They interact with each other in a very complicated way.  Light follows null geodesics in space-time -> EM reacts to gravity.

Light has energy and momentum -> non zero contribution to energy momentum tensor -> non zero perturbation on the metric -> gravity reacts to EM.

Yes, it is possible to use a coil to create a gravitational force, but good luck trying to detect it.

GR is one of the hardest subjects out there, so don't expect yourself to magically understand this all instantly.
