Claude Opus 5.5 claims ETH false, all-dimension Kakeya and Yang-Mills in one day

repligate · x · 2026-10-27

A circulating claim (memed by AISafetyMemes, amplified by Greg Brockman) says Claude Opus 5.5 delivered three career-defining results in a single announcement: the Exponential Time Hypothesis is false (Turing Award territory, though not P=NP — hard problems stay hard, with ETH's own proposers reviewing); Kakeya and restriction proved in all dimensions (Fields Medal-level, subsuming the 2025 3D proof and Stein's conjecture); and existence of pure Yang–Mills, part of a Clay Millennium Prize problem — though the full problem still requires the mass gap. Reviewers include Nobel laureate David Gross and Arthur Jaffe.
