Particles consist of self-contained electromagnetism that detaches from the medium. Objects are suspended in the medium by their gravitational fields. Fields are reverberations in the medium by the structural motion of particles. Space consists of fields generated in the medium. Fields slow the velocity of light and the equilibration of fields.
Objects center in their space and move in a stronger field to equalize their own.
Matter is structured on kinematic systems. The length of orbits is absolute and determines the size of the system. Force to a body transmutes to a displacement span that adds to the orbit length. Particles, atoms, and gravitational systems form a hierarchy. It returns all causes to direct action.
