Since Maxwell's classical electrodynamics predicts all fields propagate with speed c, these superluminal Coulomb field experiments falsify Maxwell's theory of electrodynamics. This has been proven rigorously by J.D. Jackson: Jefimenko's field expressions (which are general solutions of Maxwell's electrodynamics equations) are totally independent of the choice for gauge condition, and Jefimenko's Coulomb field is retarded with the speed of TEM waves, c.

Maxwell's theory is riddled with inconsistencies anyway, so I derived a better theory in the course of 15 years, called

*General Classical Electrodynamics* that also predicts the Coulomb field spreads with velocity much faster than c, see

http://vixra.org/abs/1512.0297. The Lorentz force law, that does not satisfy Newton's third law of motion (action-reaction principle) in case of General Magnetostatics, must be replaced by Whittaker's reciprocal force law.

The electric potential and Coulomb field must have a speed 'a' such that a>>c, because otherwise General Classical Electrodynamics does not satisfy Newton's third law of reciprocal action and reaction. I am probably the first who ever derived such a theoretical connection in science history, and it fully acknowledges rs2theory principles. I am working on a new version of General Classical Electrodynamics for a peer reviewed online Science Journal ( hrpub.org ).

Many thanks for this wonderful experiment which verifies my theory as well, and this experiment is only the beginning of something huge.
