# Destroying a near-extremal Kerr-Newman black hole

@article{Saa2011DestroyingAN, title={Destroying a near-extremal Kerr-Newman black hole}, author={Alberto Saa and Raphael Santarelli}, journal={Physical Review D}, year={2011}, volume={84}, pages={027501} }

We revisit here a previous argument due to Wald showing the impossibility of turning an extremal Kerr-Newman black hole into a naked singularity by plunging test particles across the black hole event horizon. We extend Wald's analysis to the case of near-extremal black holes and show that it is indeed possible to destroy their event horizon, giving rise to naked singularities, by pushing test particles towards the black hole as, in fact, it has been demonstrated explicitly by several recent…
