Imaginary Charge and Gravitational-Electric Space
Keywords: imaginary charge, gravitation-electric space, gravitational and electromagnetic fields
We consider the We consider the gravitational mass of a particle as an imaginary charge. A two-dimensionasl sub-space, gravitational-electric (G-E) space, is introduced to combine the imaginary gravitational charge with the real electric charge. By using this new concept, the gravitational field equations for weak gravity and low velocities can then be written in a form analogous to Maxwell's equations. With this arrangement the gravitational and electromagnet fields can be unified in the G-E sub-space, which provides a new approach to study the properties of the gravitational field. As a consequence, the gravitational energy density and energy flux would exhibit new properties with this formation.
