Unification of gravitational and electromagnetic fields

It has been a long dream of physicists to unify all the fundamental forces. It has not been very successful. The classical unification theories of Hermann Weyl, Arthur Eddington, Theodor Kaluza and Albert Einstein all have fundamental problems one way or another. The modern efforts along quantum field approach are not successful either. The Grand Unification the Theory of Everything (TOE) requires an unbelievably high energy in the order of 1019 Gev, known as the Plank energy scale, and an accelerator larger than the solar system. It is absolutely beyond our reach. It has been realized that general relativity is incompatible with quantum mechanics. Recently, we have developed a theory with mathematical rigor to unify the gravitational and the electromagnetic forces strictly within the classical framework by generalizing Newton’s law of gravitation to include a dynamic term inferred from the Lorentz force of electromagnetic interaction. An entire dynamic theory including a wave equation of gravitation is developed without any additional ad hoc hypothesis. The wave equation and its solution naturally solve the mystery of actionat- distance. One of the exciting discoveries is that the inverse square law of the static and the dynamic forces is the result of the conservation of mass (Gauss’s Law) and the total momentum (Wang’s Law). The gravitational force and the electromagnetic force are thus unified in the sense that these two forces and their propagation can be described by exactly the same set of equations.


Ling Jun Wang is a Professor of Physics at University of Tennessee at Chattanooga, USA. His research interest is concentrated on theory of gravitation, general relativity and cosmology. His representative works are the unified theory of gravitational and electromagnetic fields and the Dispersive Extinction Theory (DET) of the cosmic redshift which offers an alternative to the Big Bang cosmology.
