the theoretical (the physical and mathematical) problem is clear:
Nature is apparently built up from four point-like, independent, stable objects with two independent, conserved physical properties. Point-like mean, these objects behave above 10^-17 cm as would they have two conserved elementary charges. Since a universal uncertainty principle is valid, the exact positions and the exact velocities of the elementary objects are unknown. (Just the same way, it is unknown if the four objects have an inner structure below 10^-17 cm which produce the four “point-like” objects with both physical properties. But, it is assumed that above 10^-17 cm no more stable objects and no more physical properties of the objects are existing.)
The two kinds of conserved elementary charges of the objects – they are the physical properties – generate two kinds of independent, continuous, non-conservative fields which propagate with c. The interactions between the stable objects above 10^-17 cm is described with the two independent fields.
Bill, you have the absolute freedom to do everything in regions below 10^-17 cm, but above 10^-17 cm the just described physical properties must come out.
