TL;DR: It is emphasized that the physical processes during the collapse and their outcome depend significantly on the type of wormhole and how black holes arise in the collapse of wormholes.
Abstract: Based on Khalatnikov’s ideas, we consider the physical processes that arise in the collapse of wormholes of different types. We emphasize that the physical processes during the collapse and their outcome depend significantly on the type of wormhole. We consider in detail how black holes arise in the collapse of wormholes.

TL;DR: In this article, a model of a star consisting of vacuum-like matter is constructed in the framework of general relativity and its stability and other physical properties are analyzed, and compared with cosmological models consisting of the same vacuumlike matter with a pressure equal to the energy density but with the opposite sign.
Abstract: A model of a star consisting of vacuum-like matter is constructed in the framework of general relativity. Its stability and other physical properties are analyzed. This stellar model is compared with cosmological models consisting of the same vacuum-likematter with a pressure equal to the energy density but with the opposite sign.
