4D Einstein-Maxwell energy density analysis initiates with the fact the quantum composed in the total field formal frame of the energy density J m^(-3) = -Pa = kg m^(-3) mass density dualistic units along the trace of the electromagnetic stress tensor T???? of the Einstein equations, requires the negative outward pressure -Pa of quantum energy E = hc/?? to have some nonstandard basis for the missing quantum 3D volumetric ?? parameterization beyond the zero-dimensional (0D) Dirac delta functional ?? imaginary-invisible mathematical point particle QED-Standard Model representations of the quantum mechanical observables. Accordingly, the present nonstandard 4D photon string-like cylindrical coordinate transverse lemniscate expansion of the Poynting energy flux vector S = 1/??
