Naked singularity, firewall, and Hawking radiation

Understand

Spacetime singularity has always been of interest since the proof of the Penrose-Hawking singularity theorem.

• Naked singularity naturally emerges from reasonable initial conditions in the collapsing process.
• A recent interesting approach in black hole information problem implies that we need a firewall to break the surplus entanglements among the Hawking photons.
• Classically, the firewall becomes a naked singularity.
