Phase Conjugation Feynman Diagrams by Douglass A. White, Ph.D. dpedtech.com All physical phenomena are mediated by electro-magnetic (EM), gravitational (G), strong, or weak interactions. We can further simplify this scheme by noting that ALL interactions among any kind of particles or waves are governed by the laws of phase conjugation and involve 4-particle/wave mixing of some kind. Thus, in a formal sense all Feynman diagrams should take the form of 4-particle/wave mixing phase conjugation diagrams. In this way we can update some Feynman diagrams found in physics books (including some shown in Observer Physics, chs 11-13.) In this article I provide a few examples of how we can use the model of phase conjugation to explore the inner workings of physics with Feynman diagrams. In the following diagrams left-to-right represents passage of time, and the vertical dimension represents translation in space. The dashed arrows represent bosons and the solid arrows represent fermions. The star wave sign (*) represents an antiphoton or other antiparticle. Mathematically it is the conjugate wave function. Charge is represented as (-) or (+), the plus sign also indicating the antiparticle of the negative particle. Here is a Feynman diagram of an EM interaction in which an excited outer orbit electron (e-) changes energy levels and emits a photon (g). Drawn in left-to-right mirror image with arrows reversed it represents an electron absorbing a photon. The presence of an antiphoton (g*) indicates an observer. The antiphoton goes faster than light and thus backward in space/time, so its arrow direction is opposite that of the photon. Fermion particle antimatter pairs also move opposite directions in time, though they usually scatter at angles from each other in space. The electron in this diagram drops to a lower orbital and emits a photon. Standard Feynman diagrams of electrons or positrons interacting with photons are usually Y-shaped. They ignore an anti-photon that travels in tandem with the photon. The whole interaction is a phase conjugation quantum bubble. The anti-photon is an eeg
