The roots of Gravity in Electrodynamics (original) (raw)

Two of the fundamental interactions in nature, electrostatic and gravitational, show well known striking similarities both acting over long range and following the inverse square law of the distance. In fact, Coulomb’s law and Newton’s law of gravitation are formally identical. Is this a coincidence or does it indicate that the two laws have a common root? It seems to us that physics has answered this question by pure chance, at least tacitly. We, on the other hand, do not believe in chance. A hypothesis of the common root of the two interaction is proposed here on the basis of which gravity is the effect of the electrodynamic interaction between electrically neutral bodies. We assume that the presumed symmetry of the at- tractive and repulsive forces exchanged by a charge with two of equal value and opposite sign is only the consequence of an imprudent generalization made on the basis of measurements unable to detect a small asymmetry which sees the attraction very slightly exceed the repulsion. It follows that two co-located and equal magnitude electric charges of opposite signs generate a not null net electric field. We show how, with this single hypothesis, the entire electrodynamics of electrically neutral bodies can be constructed. We also show the results obtained applying the theory to some significant experimental cases such the light deflection in a gravitational field, a planet perihelion precession, the power radiated by merging black holes. Moreover, we demonstrate that the mystery surrounding measures of G that do not converge to a single value could be unfounded. We show how G depends on the chemical composition of the interacting bodies and how it can be calculated with good agreement with the measured values.
