Transitional Layer at the Edge of a False Vacuum in a Cavitation Model of the Big Bang

This article presents the authors’ proposed theory on the formation of cavitation voids in the false vacuum during the inflationary phase of the Big Bang. It examines the structure of, and the physical processes occurring in, the transition region at the boundary between the false and physical vacuums. It has been demonstrated that, during the formation of physical vacuum voids (regions in which the Λ-term, a constant in the equations of general relativity, goes to zero), conditions arise in the transition region between the false vacuum and the physical vacuum that allow for the formation of a narrow layer of matter. This layer may be the precursor to the bridges observed in the large-scale lattice structure of the universe. The mechanism of bubble expansion during the inflationary phase of the universe is examined. It has been demonstrated that the inflationary phase of expansion passes into the standard Big Bang model due to the conversion of the false vacuum into matter at the boundaries of the bubbles. This model does not require the universe to undergo an extremely rapid expansion to explain the quasi-homogeneous and isotropic distribution of matter and the cosmic microwave background. Furthermore, it can account for the formation of the large-scale lattice structure of the universe. The estimated radii of cosmic voids are consistent with observational data.
