Abstract: We investigate the formation of trapped surfaces
in cosmological spacetimes, using constant mean curvature slicing.
Quantitative criteria for the formation of trapped surfaces
demonstrate that cosmological regions enclosed by trapped surfaces may have
matter density exceeding significantly the background matter density
of the flat and homogeneous cosmological model.
