Unification of Electromagnetism and Gravitation

Using four field equations, a recently proposed classical field theory that covers the phenomenology of classical physics at the level of the Maxwell and Einstein Field Equations (M&EFEs) but then goes further by unifying electromagnetic and gravitational phenomena in a fundamentally new way is reviewed. The four fundamental equations are shown to determine the dynamic fields of the theory in a manner that is logically consistent with the requirements of general covariance. Developing particle-like soliton solutions and then radiative solutions for electromagnetic and gravitational waves, the predictions of the theory are shown to be consistent with those of the M&EFEs. The same solutions are then used to illustrate the unification that the theory brings electromagnetic and gravitational phenomena by, for example, uniting electromagnetic radiation with a specific class of underlying gravitational radiation. A description is given for quantizing the mass, charge and angular momentum of particle-like soliton solutions, a situation that is uniquely possible with the new theory because the mass density and charge density are treated as dynamic fields and not introduced as external parameters. A cosmological solution corresponding to a homogeneous and isotropic universe is investigated. Finally, a description of antimatter is naturally accommodated by the theory and leads to definite predictions regarding the interactions of matter and antimatter with gravitational fields.
