Global visibility of a strong curvature singularity in nonmarginally bound dust collapse

22 Aug 2020 Mosani Karim Dey Dipanjan Joshi Pankaj S.

We investigate here the local versus global visibility of a space-time singularity formed due to the gravitational collapse of a spherically symmetric dust cloud having a non-zero velocity function. The conditions are investigated that ensure the global visibility of the singularity, in the sense that the outgoing null geodesics leave the boundary of the matter cloud in the future, whereas, in the past, these terminate at the singularity...
