Description |
We show that the occurrence of naked singularities as the end-state of the complete gravitational collapse of a spherical massive cloud of matter in the General Relativistic framework is a generic feature. Collapse models with tangential pressures are just as likely to form a naked singularity as a black hole and the introduction of such pressures can 'undress' an otherwise covered singularity. As an example we show how perturbing the Oppenheimer-Snyder dust collapse model with a small tangential pressure can lead to the formation of a naked singularity. |
