What Survives Inside A Black Hole?

Sep 26, 2026 · 18m

Summary

This episode explores the "no hair" conjecture, explaining why black holes are defined solely by mass, charge, and angular momentum. It details how Gauss's law and infinite-range forces allow these properties to persist in external fields despite the event horizon. The discussion connects this to quantum mechanics, highlighting that local conserved quantities like baryon number are lost, setting the stage for the black hole information paradox.
