Explore how stringy effects smooth out black hole singularities in this 41-minute conference talk from the Workshop on Quantum Aspects of Black Holes and Spacetime at the Institute for Advanced Study. Delve into the AdS/CFT correspondence where black hole singularities manifest as divergences in analytic continuations of two-point functions, corresponding to null geodesics bouncing off singularities. Examine how these geodesics behave at finite 't Hooft coupling through the lens of the SYK model, discovering that stringy effects create smoothing mechanisms. Learn about the connections between this quantum gravitational phenomenon and classical dynamical systems, and understand how these computational approaches extend to matrix quantum mechanics. Gain insights into cutting-edge research on quantum gravity, black hole physics, and the holographic principle from Harvard University researcher Matthew Dodelson's presentation delivered on December 5, 2025.
