Magnetic Theory of Gravitation
Recently a generalization of Einstein’s theory of gravitation has been proposed which can accommodate the gravitational monopoles. The generalization is made in such a way that the equations of motion become exactly symmetric under the dual transformation of the curvature tensor. The theory is characterize by a fundamental scale к which can be interpreted as a “magnetic” mass. In exact analogy with the Dirac’s generalization of Maxwell’s theory, the theory can be made sensible only if the energy E is quantized by the condition к E = 2πn, where n is an integer. We review the recent development on the subject.
