About structure of fields and stability of electrostatic formations in vacuum
Let's consider vacuum as two-component gas of rather small density with the distributed charge of two signs pe., pe+ and the distributed gravitational mass pp. However, the gas medium, apparently, should contain small areas with uncompensated charges pe and p.+ to support some average level of density of energy in vacuum [I]. The inspissation of charges as particles in such places is possible, both their normalized electncal and gravitational potentials are described by relations of a kind (I):
