20. Electrodynamics IS NOT an independent description of Nature.

Electrodynamics is just an alternative expression of the single dynamical interaction in Nature – the universal energy transfer. All electrodynamic physical quantities, if squared, are equivalent to specific dynamical quantities. For example, electric current squared is equivalent with dynamical force, electric charge squared, when multiplied with acceleration, is equivalent with energy, magnetic field squared is equivalent with the speed of light, or the electric field squared is equivalent with the cube of the speed of light.
