Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions | Lex Fridman Podcast #468
Janna Levin frames black holes as causal boundaries rather than objects, shifting frontier physics toward information, geometry, and quantum structure.The information paradox pits general relativity’s apparent information loss against quantum mechanics’ unitarity, with holography and ER=EPR suggesting spacetime may emerge from entanglement.LIGO shows the payoff from sustained frontier infrastructure: after a first generation detected nothing, its second recorded a black-hole merger on September 14, 2015, while quantum gravity and extra dimensions remain unresolved.
