The Black Hole Information Paradox

Sep 25, 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 famous bet between Stephen Hawking and John Preskill and introduces Gerard 't Hooft’s discovery that black holes may be holograms, leading to the holographic principle. The discussion also covers black hole complementarity, the firewall paradox, and answers listener questions regarding charged black holes and virtual particles.
