HYPOTHESIS 4. “Any material body consists of two components: visible and invisible. The visible material component we characterize by mass m. The invisible component is a body shell in the form of an attached vortex of the medium of the electromagnetic field. The invisible field component we characterize by the electromagnetic (relativistic) mass m. The electromagnetic mass determines the characteristic properties of particles and ensures their interactions.”
