  In this paper, we propose a model for the initial stage of the development of
the Universe, analogous to cavitation in a liquid in a negative pressure field.
It is assumed that at the stage of inflation, multiple breaks of the metric
occur with the formation of areas of physical vacuum in which the generation of
matter occurs. The proposed model explains the large-scale isotropy of the
Universe without ultrafast inflationary expansion and the emergence of a
large-scale cellular (cluster) structure, as a result of the development of
cavitation ruptures of a false vacuum. It is shown that the cavitation model
can be considered on par with (or as an alternative to) the generally accepted
inflationary multiverse model of the Big Bang.
