A resolution of spacetime singularity and black hole paradoxes through avoidance of trapped surface formation in Einstein gravity
Rituparno Goswami, Pankaj S. Joshi
The occurrence of a spacetime singularity indicates the breakdown of Einstein gravitation theory in these extreme regimes. We consider here the singularity issue and various black…
Gravitational Collapse End States
Pankaj S Joshi
Recent developments on the final state of a gravitationally collapsing massive matter cloud are summarized and reviewed here. After a brief background on the problem, we point out…
Naked Singularity formation in scalar field collapse
Rituparno Goswami, Pankaj S Joshi
We construct here a class of collapsing scalar field models with a non-zero potential, which result in a naked singularity as collapse end state. The weak energy condition is satis…
The critical role of shear in gravitational collapse
Pankaj S. Joshi, Rituparno Goswami, Naresh Dadhich
We investigate here how the shearing effects present within a collapsing matter cloud influence the outcome of gravitational collapse in terms of formation of either a black hole o…
Cosmic Censorship: A Current Perspective
Pankaj S. Joshi
End state of gravitational collapse and the related cosmic censorship conjecture continue to be amongst the most important open problems in gravitation physics today. My purpose he…
Gravitational Collapse
P. S. Joshi
We review here some recent developments on the issue of final fate of gravitational collapse within the framework of Einstein theory of gravity. The structure of collapsed object i…
