Abstract

We investigate the final fate of spherical dust collapse by using the orthonormal frame formalism with the Hubble normalized variables and the separable volume gauge, which is usually used for analyzing cosmological dynamics. As a result, we find that the final fate of spherical dust collapse is characterized by the quantity concerned with the energy density in this formalism. We discuss the final fate of spherical perfect fluid collapse with a barotropic equation of state and conjecture a criterion for the final fate of spherical gravitational collapse.
