Perhaps the most far-reaching of all the applications of self-field theory is in the area of photonics. Photonics plays a major role in DNA transcription. Obviously this has profound implications for health, both physical and mental. Progress in photonics has been limited by constraints imposed by current quantum field theory (QFT) with its reliance on the uncertainty principle. That the photon has an internal structure, in addition to mass, is beyond mainstream conceptions. It just does not happen, according to QFT in its current form. Nevertheless, knowledge of the photon's internal structure allows us to comrehend the forms of various fields required by the weak and strong nuclear forces. Atomic and nuclear function may well play a role in how our minds store sights and sounds, as well as how our long-term memory functions, in addition to the vital role played by photons within the cell cycle. These biological processes have of recent been classified as biophotonics in distinction to the photonics of 'hard physics'.

The photon's structure rotates as it radiates simplifying our understanding of relativity, special and general. These rottaions cause SR and GR to become almost trivial to understand. That photons inside atoms are found to move in spinorial streams between nucleonic and electronic regions allows a vision of the fields at the various other levels, such as the solar system and the galactic level. Now the physics of dynamic equilibrium between remote objects becomes apparent. Now the fields are no longer ubiquitous but stream to and fro between interacting particles at any level of self-field theory; particle and field obey the same Maxwell-like equations . The particle-wave duality is clarified by the simple internal structure of the radiating photon; it is no longer a massless point-object, but a structured piece of matter that has no mass at its time-averaged centre. In fact it could be the so-called 'dark matter' of the universe; it cannot be seen by us or our instruments on earth because it is heading somewhere else and not into our retinas or (radio-) lenses on earth.

The internal structure of the photon can be described via EMSFT Photon Chemistry.pdf 175 kB-left click to view, right click and 'save file as'[Fleming and Bauer 2004] whereby the ordinary photon consists of two sub-particles of equal mass and opposite charge in dynamic equilibrium with each other. The sub-photonic particles are termed the phectron and the phroton, corresponding to the electron and proton of the hydrogen atom. As in the application of EMSFT to the hydrogen atom, the mathematical description of the photon has degrees of freedom associated with the electric (E-) and magnetic (H-) fields, the electric permittivity e and the magnetic permeability µ of a region. Since there are two fields per sub-particle (E- and H-fields), there are six degrees of freedom altogether. EMSFT provides eigensolutions for the simple photon and its compounds. Analogous to the spectroscopy of the hydrogen atom, the simple photon can exist in a range of energy states that depend on the motions of the phectron and phroton. Analogous to atomic chemistry, the photon exists as compounds wherein the various sub-photonic structures assume distinct entities. Including the 'ordinary' photon found in the terrestrial domain, these compounds correspond to the bosons and gluons that mediate the EM, weak and strong nuclear forces known to physics. In regions where gluons exist, the equations controlling the fields are a modified version of Maxwell’s two curl and two divergence equations. For the strong force there are three curl and three divergence equations, there being a new type of field herein termed the nuclear field that depends upon compounded triplets of the phectron and phroton. There is evidence for a photonic chemistry found in nature, including the layered spherical structure of the ionosphere, the various snowflake structures, and hydration structures found in and around DNA and other important biological proteins. It appears that a photonic chemistry may be similarly involved in energy/temperature dependent processes such as the cell cycle.
