A Princeton mathematician says wormholes cannot survive Einstein's equations, and the AI apocalypse is absurd. A solution that vanishes under a small nudge is a ghost, not physics.
Sergiu Klainerman is a mathematician at Princeton University. With Demetrios Christodoulou, he proved that empty spacetime is stable.
We cover: What makes a solution of Einstein's equations physical, why slowly rotating black holes pass the stability test and wormholes fail it, why shocks form no matter how small the perturbation, whether AI can reproduce a landmark proof, and why he calls the AI singularity absurd.
Mathematics is discovered, not invented.
