Black Hole: The Interior Spacetime

Understand

The information loss paradox is often discussed from the perspective of the observers who stay outside of a black hole.

• However, the interior spacetime of a black hole can be rather nontrivial.
• We discuss the open problems regarding the volume of a black hole, and whether it plays any role in information storage.
• We also emphasize the importance of resolving the black hole singularity, if one were to resolve the information loss paradox.
