Information loss, made worse by quantum gravity?

Understand

Quantum gravity is often expected to solve both the singularity problem and the information-loss problem of black holes.

• This article presents an example from loop quantum gravity in which the singularity problem is solved in such a way that the information-loss problem is made worse.
• Quantum effects in this scenario, in contrast to previous non-singular models, do not eliminate the event horizon and introduce a new Cauchy horizon where determinism breaks down.
• Although infinities are avoided, for all practical purposes the core of the black hole plays the role of a naked singularity.
