Black Hole Singularity and the Fate of Black Holes

In the previous two chapters, we first investigated the physics of (analogue) Hawking radiation in the semiclassical regime, and then we moved on to investigate quantum cosmology (partly to learn the existing Euclidean techniques to deal with possible quantum gravity effects that may resolve issues regarding singularities). In this chapter, it is about time to apply similar Euclidean approach to black hole information paradox to resolve the long-standing puzzle originated from the black hole singularity.
