Quantum gravity might actually peel the 'skin' off a black hole, leaving its infinite-density core totally exposed to the universe.

The Takeaway
A fundamental rule of space called 'cosmic censorship' says that the breakdown of physics at the center of a black hole must be hidden behind a point of no return. This new model shows that quantum mechanics might allow spinning black holes to lose this cloak, creating a 'naked singularity' visible to the outside world.
From the abstract
Recently, for the first time, a metric of a static spherically symmetric generalized uncertainty inspired quantum black hole was derived. We apply the modified Newman-Janis algorithm to this metric and derive its rotating counterpart. We show that this metric has all the correct limits, while due to Newman-Janis side effects, the singularity which was resolved in the static case, is introduced back into the model. However, the slowly-rotating limit of this black hole is singularity-free. Further
