Robert "Bob" Wald - Black Holes and Quantum Gravity

In this video series entitled "Conversations at Niels Bohr's Office" Johan Samsing from the Niels Bohr Institute presents conversations with some of the most influential physicists and thinkers of over time on topics related to the fundamental physics of our Universe.
Each episode is recorded at the historical Niels Bohr's Office and based on one long take with no script, with the intention of creating a more natural conversation about whatever topics the guest wants to highligt.
2. Episode: "What can Black Holes tell us about Quantum Gravity?"
Robert M. Wald is an American theoretical physicist and professor at the University of Chicago, known for his groundbreaking work on general relativity, black holes, and quantum gravity. For this, he recently received the Einstein Prize from the APS Division of Gravitational Physics for "the discovery of the general formula for black hole entropy, and for developing a rigorous formulation of quantum field theory in curved spacetime."

I really miss my days at University of Chicago Physics department with the Gravity group.

Penrose's gravitational singularity is a pure failure.
