Title: Unification of gravitational and electromagnetic forces


Biography: Ling Jun Wang


It has been a dream of physicists to unify all the fundamental forces over at least a century. The Grand Unification Theory (GUT) requires an unbelievably high energy in the order of 1016 GeV and an accelerator larger than the solar system. It is apparently beyond our reach in the fore seeable future. The last stage of this dream is the Theory of Everything (ToE), which includes the gravitational force in its unification, which requires an even higher energy—known as the Plank energy scale, about 1000 times higher than the GUT energy scale. Moreover, it has been realized that general relativity is incompatible with quantum mechanics. The approach of describing gravity in the framework of quantum field theory fails at short distances of the order of the Planck length. 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 action-at-distance. It has been discovered that the inverse square law of the static and the dynamic forces is the result of the cons. It has been shown 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 and the electromagnetic forces are unified in the sense that these two forces and their propagation can be described by exactly the same set of equations.
