Gravitational Collapse of a Massive Star and Black Hole Formation

Abstract

This paper discusses the final fate of a gravitationally collapse of a massive star and the black hole formation. If the mass of a star exceeds Chandrasekhar limit then it must undergo gravitational collapse. This happens when the star has exhausted its nuclear fuel. As a result a space-time singularity is formed. It is conjectured that singularities must be hidden behind the black hole region which is called the cosmic censorship hypothesis. It has not been possible, to obtain a proof despite many attempts to establish the validity of cosmic censorship and it remains an open problem. An attempt has been taken here to describe causes of black hole formation and nature of singularities therein with easier mathematical calculations.
