The Theory of Direct Particle Interaction and a Stationary Cosmological Model

The theory proposed in our previous work, describing electromagnetism, the emergence of particle masses and gravity as manifestations of a unique direct particle interaction is further developed. The electromagnetic interaction is primary in this theory, whereas the origin of masses and gravity can be considered as its consequences. The key ideas of the theory are the consideration of the advanced interaction along with the retarded one and inclusion of the Mach principle. A new element inserted to the theory in the present paper is the irreversibility mechanism described by Norman and Stegailov in molecular dynamics. This mechanism leads to cutting of the action radius of the electromagnetic interaction, making it possible to combine the theory with a stationary cosmological model and to solve a number of issues that remained open in our previous paper. The resulting equation motion for particles repeats the previous one but is justified in more detail. New results include the fact that the cosmological coincidences, previously used as postulates, are now consequences of the theory.
