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.
