Answer :

Planck's Constant signifies the Photon Charge, and the Aether of "free space'. Photon energy is E=hf =hc/r = Q2zc/r and Q is the photon charge in Coulombs.. Planck's Constant is also related to the free space impedance z=375 Ohms. h=QWb = Q2z gives z=Wb/Q. Wb is the Quantum magnetic "charge" in volt seconds or Webers. Q=4/3 E-18 Coulomb and Wb= 500 E-18 Webers and h= QWb = 2/3 E-33. Maxwell believed that electromagnetic waves required a "medium" to propagate the waves. The free space impedance z, is evidence of this medium. The photon charge is Q=(13U,1d) in Quarks, 13x2/3 + 1x-1/3 = 25/3 electrons.. The photon charge is related directly to the fine Structure Constant, alpha = 1/2( e/Q)2= 1/2 (.16/4/3)2 = 1/2 (.48/4)2= 1/2(.12)2= 1/2 (.0144)=7.2E-3. I believe that the electron is an effect
