Research Seminars: Quantum Gravity & Black Holes
A curated collection of 138 research seminars on quantum gravity, black holes, and de Sitter space — featuring talks on the Hartle-Hawking state, black hole information paradox, holographic algebras, semiclassical gravity, and spacetime emergence. These are advanced research-level talks from leading experts in the field.

Quantum Mechanics of the Hartle-Hawking State - Jordan Cotler
The Hartle-Hawking Wavefunction and de Sitter Black Holes - Gustavo Joaquin Turiaci
An Observer's Measure of De Sitter Entropy - Mehrdad Mirbabayi
Comments on the de Sitter Double Cone - Zhenbin Yang
On the Phase of the de Sitter Density of States - Douglas Stanford
Observers, Alpha Parameters, and the Hartle-Hawking State: Part II - Ying Zhao

About These Seminars
These 138 research talks cover frontier topics in quantum gravity, including the Hartle-Hawking no-boundary proposal, de Sitter holography, the black hole information paradox and its modern resolutions (islands, replica wormholes), spacetime emergence from entanglement, and semiclassical gravity. Speakers include many of the leading researchers in the field.
