Explore a fascinating physics seminar where Hong Liu from MIT delves into holographic duality and the emergence of geometric concepts in quantum gravity systems. Learn how a higher dimensional quantum gravity system relates to a lower dimensional conformal field theory (CFT) with numerous degrees of freedom. Discover the framework explaining how spacetime subregions, various notions of time, and causal structure materialize from the dual CFT perspective. Gain insights into this complex theoretical physics topic through an in-depth 81-minute presentation that bridges the gap between quantum gravity and conformal field theory.
