- The event horizon is not a wall or surface — it is a mathematical boundary defined by the point where escape velocity equals the speed of light - For a supermassive black hole (billions of solar masses) you could cross the event horizon without feeling anything unusual — tidal forces at the horizon are negligible - Hawking radiation: quantum mechanics predicts black holes slowly evaporate through virtual particle pair production near the horizon — for stellar-mass black holes the temperature is 60 nanokelvin, colder than the CMB - The information paradox: if a black hole evaporates completely via thermal Hawking radiation, where does the information about everything that fell in go? Unresolved after 50 years - LIGO's gravitational wave detections since 2015 have confirmed black hole mergers match GR predictions to extraordinary precision — but tell us nothing about what happens inside the horizon
