Classical and quantum aspects of radiation fluid shells: Black holes and wormholes, mass amplification, light dark matter

A spherically symmetric thin shell out of the matter satisfying the ultrarelativistic state equation (radiation fluid) is considered. Description of black holes and traversable wormholes formed by such shells is given. We prove the theorem on the static states of shells of these types. The motivation of classical wormholes instability and restriction on the total energy becomes the corollary of this theorem. The effect of nonlinear amplification of the observable mass is stadied. We formulate the hypothesis that the dark matter problem consists not in the existence of a special matter but for lack of free light as such and its transmutation into a mass of light black holes and wormholes. Also on the basis of this model, the evaporation of quantum black holes is demonstrated, and suggestions on condensation of the quantum wormholes are proposed.
