Ever since Hawking's discovery that quantum black holes radiate, a microscopic
understanding of this phenomenon has been a litmus test for a consistent theory of
quantum gravity. An idea that has transformed the field, and occupied center stage
during the past two decades, is to consider the black hole horizon as a holographic
screen on which the black hole interior is recorded.
In its precise formulation, known as AdS/CFT correspondence, the book-keeping
device is a local quantum field theory similar in nature to the familiar quantum
electrodynamics. In the first part of the talk I will describe these far-reaching ideas. As
an application, I will then explain how AdS/CFT correspondence might help answer a
long-standing theoretical question: can there exist more than one gravitons?
