Throats as macroparticles on the basis of spherically symmetric solutions to the Einstein-Maxwell equations

Exact spherically symmetric solutions to the equations of general relativity for dust, the electromagnetic field and electrically charged dustlike matter, containing throats, are used for a gravitational description of macro- and microobjects like a universe, pinch plasmoids, and atomic nuclei. The observed universe is shown to be possibly a maximon. The nature of plasmoids forming in experiments with high-voltage discharges can be gravitational. A good agreement is observed between the estimated radii of atomic nuclei with high mass numbers based on the gravitational interaction and the empirical ones.

Particular solution of self-consistent-field equations of charged liquid

The system of Maxwell equations and Euler equations describing the interaction of a charged liquid with its intrinsic electromagnetic field reduces to nonlinear equations of a vector field. A class of accurate particular solutions is obtained for equations of motion in which, for media with a constant invariant density, the field equations transform to equations of Prock type.
