Query: Destroying the event horizon of regular black holes   Recently, several authors have studied the possibility of overspinning or
overcharging an existing black hole to destroy its event horizon and make the
central singularity naked. When all the effects are properly taken into
account, any attempt to destroy the black hole seems to be doomed to fail, in
agreement with the weak cosmic censorship conjecture. In this letter, we study
the possibility of destroying the event horizon of regular black holes. These
objects have no central singularity and therefore they are not protected by the
cosmic censorship hypothesis. Our results strongly support the conclusion that
regular black holes can be destroyed. If we believe that the central
singularity in astrophysical black holes is solved by quantum gravity effects,
we might have a chance to see the black hole's internal region and observe
quantum gravity phenomena. As our finding implies the violation of the black
hole's area theorem, the collision of two black holes may release an amount of
energy exceeding the Hawking bound, which can be experimentally tested by
gravitational wave detectors.
