Can Black Holes Integrate General Relativity & Quantum Mechanics?
Summary
This episode explores the black hole information paradox and the proposed solution of black hole complementarity, which suggests that quantum information can exist both inside a black hole and in its Hawking radiation without violating unitarity. The host uses Penrose diagrams to demonstrate that no single observer can ever detect both copies of the information simultaneously, rendering the apparent contradiction unobservable.
