On the spheric radiation

Summary form only given. Without any additional assumption a sourceless electrodynamic radiation field is derived, which, though not having any material limitations, does not expand in the course of time. Once generated in the absolute vacuum it can subsist unlimited and can be used therefore as a base for the explanation of solid particles. Being created as an occasional by-product of a curved lightning stroke it is per se no plasma phenomenon. Consequently, with respect to its energy content it has not the narrow limitations, which occur at plasma objects because of the virial theorem.
