The Black Hole Information Paradox

Oct 29, 2026 · 20m

Summary

This episode explores the black hole information paradox, explaining how Hawking radiation appears to destroy quantum information in violation of fundamental physics. It details the historical debate between Stephen Hawking and John Preskill, the concept of black hole complementarity, and Gerard 't Hooft’s discovery that led to the holographic principle. The discussion concludes with answers to listener questions regarding charged black holes and the nature of virtual photons.
