Abstract

The dynamical evolution of a locally open region in a closed universe is considered. This is done by using Tolman's solution for an inhomogeneous closed model filled with the pressureless matter. It is shown that the unbounded expansion of the open region will be stopped by the particles invading the region through the caustics which necessarily form. A hypothesis is put forward according to which general nonsimultaneous collapse is an unavoidable fate of any closed universe.
