0 electrodynamics electromagnetism-general relativity

The process of proton-electron interaction in the STC, described here is in fact interaction between their masses, but the outcome of that interaction is the production of the electromagnetic field. This hypothetical process shows a direct connection between the phenomena covered by the theory of general relativity and electrodynamics phenomena [5,16,20,21]. 

To consider magnetic flux density components of IAIV, Q must have the units of weber and R, the scalar curvature, must have units of inverse square meters. In the flat spacetime limit, R 0, so it is clear that the non-Abelian part of the field tensor, Eq. (6), vanishes in special relativity. The complete field tensor F vanishes [1] in flat spacetime because the curvature tensor vanishes. These considerations refute the Maxwell-Heaviside theory, which is developed in flat spacetime, and show that 0(3) electrodynamics is a theory of conformally curved spacetime. Most generally, the Sachs theory is a closed field theory that, in principle, unifies all four fields gravitational, electromagnetic, weak, and strong. 

Spectroscopy. Microwave radiation is used for electron paramagnetic resonance, also known as electron spin resonance, analysis, which has been crucial in the development of the most fundamental theories in physics, including quantum mechanics, the special and general theories of relativity, and quantum electrodynamics. Microwave spectroscopy is an essential tool for the development of scientific understanding of electromagnetic and nuclear forces.
