Electromagnetic wave, electromagnetic field and quantas

AI Thread Summary
The discussion revolves around the relationship between electromagnetic fields and gravitational fields as described by Einstein's theory of spacetime. It emphasizes that while gravitational waves have been detected, the nature of electromagnetic waves within this framework is less clear. Participants clarify that there is no mechanical explanation for electromagnetism based on inertia and elasticity, as these concepts are merely metaphors. Instead, quantum electrodynamics serves as the fundamental model for understanding electromagnetism, operating within a Minkowski geometric background. The conversation encourages exploring Einstein's original 1905 paper for foundational insights into these concepts.

As I understand space time fabric is exclusively the Gravitational field according to Einstein.So every field wave or interaction is contained in the Gravitational Field.This fabric of spacetime(gravitational field) is having properties of inertia and elasticity that is why gravitational waves are possible and have been detected in LIGO antennae.
Now my problem is to know how electromagnetic fields and their waves are acting in this container( all pervading ) fabric of spacetime(Gravitational field).
Also electromagnetic wave is possible due to elasticity and inertia properties of the vacuum(again spacetime and hence Gravitational field).So both gravitational wave and electromagnetic wave and their quantas and their generating fields are there in all pervading spacetime(finite and unbounded as I understand).Yes I understand that gravitational field itself is the container.
I want to understand the exact picture of locations and distributions of all fields ,waves and quantas(appearing on interactions of probably fields)
Please correct me if my query is irrelevant. Thanks

You seem to want a mechanical explanation for electromagnetism in terms of inertia and elasticity. There is not one.

There is no mechanical fabric of space time with inertia and elasticity in the first place. That's just a crude metaphor. Electromagnetism is not explained in terms of such a fabric anyway. More generally in physics there is no mechanical explanation for anything. Mathematical models are as good as it gets. Quantum electrodynamics is the most fundamental model we have for electromagnetism. It operates on an assumed background of Minkowski geometry.
 
Thanks!
 
This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...
Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'
Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
