The foreground field locally around a charged particle, for example an electron, is the electrical lines of force generated by the unit electrical charge of the electron. The energy rotation around an electron expresses the electrical charge of the electron through electrical lines of force which emanate from the electron and cover great distances. The presence of mass-energy causes a corresponding gravitational field. The foreground field is another view of the gravitational field, only from the view point of the geometry the electrical lines of force emanating from every charged particle with mass-energy. The more familiar view of the gravitational field is the curvature of spacetime caused by the presence of mass.
Energy units attract each other.
The net electrical force acting on any particle is the result of the interaction of the foreground field with the lines of force of that particle. The energy particles move at very great speeds, far in excess of the speed of light within their evacuated paths. It is energy interacting with the background that can only happen at the speed of light. The electrical charge generated by an electron reaches apparently an infinite distance. So if the energy particles traces the electrical lines of force, then each rotation the energy particle travels the entire electrical field of the particle.
