Except for proposing the fuzzball as a solution for black hole singularity, has string theory successfully explained/dealt with any other form of spacelike or timelike singularities? Kindly explain

  • $\begingroup$ Not at all an expert, but I think that it resolves all the singularities in principle in certain asymptomatic AdS spacetimes due to the AdS/CFT correspondence. I might very well be erred. $\endgroup$ – Dvij Mankad Jun 30 '18 at 20:28

    $\begingroup$ Also, you might be interested in a recent critique of the fuzzball program: arxiv.org/abs/1804.10616. $\endgroup$ – Dvij Mankad Jun 30 '18 at 20:32
  • $\begingroup$ Ok, thanks. I am not so sure about the big bang singularity though. Has string theory given any stable solution? I don't know. There are models though that seeks to replace the classical singularity by replacing the classical geodesics with quantum or Bohmian trajectories. But they don't apply string theory. I will go through the paper given in the link. Suvrat Raju's ideas always make us think about these problems in a different way $\endgroup$ – Only1INDRAJIT Jul 2 '18 at 2:25
  • $\begingroup$ @DvijMankad For black holes embedded in asymptotically AdS spaces, even if there is a dual CFT, AdS/CFT doesn't describe the black hole's interior. Comment to OP: By "resolution of singularities" you might want to look at the identification of Dbranes with black p-branes, which are higher dimensional generalization of charged black holes. $\endgroup$ – Bruce Lee Jul 16 '18 at 22:04
  • $\begingroup$ @BruceLee Yes, I know there are issues with describing the black-hole interior. In particular, there has been no explicit success in describing the interior using the AdS/CFT correspondence. But, if the AdS/CFT correspondence is true in its entirety then, in principle, there must be a consistent description of the interior using the AdS/CFT correspondence. This is what I meant. Correct me if I am wrong. $\endgroup$ – Dvij Mankad Jul 16 '18 at 22:26
