Claude solved a 23-year-old black hole calculation and two open theoretical physics problems
claudeai · x · 2026-11-10
Anthropic reports Claude Fable 5.2 solved two open problems in theoretical physics related to black holes. The first: completing a laborious calculation unsolved for 23 years — showing the Hawking-Page transition remains first-order at weak coupling (b = -1.48×10⁻³ λ²), answering a question posed in 2003. The thread also covers an MIPLIB train-scheduling problem where agents beat the best known timetable by 2.6% in under two hours and proved optimality, with solutions submitted for public verification.
