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…
A black hole mass threshold from non-singular quantum gravitational collapse
Martin Bojowald, Rituparno Goswami, Roy Maartens +1
Quantum gravity is expected to remove the classical singularity that arises as the end-state of gravitational collapse. To investigate this, we work with a toy model of a collapsin…
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…
