2607.02861 Minimal-Repair Minimum-Viable Geometric Unity: Classical Formalization, Weakness Enumeration, and Multi-Axis Consistency Analysis
Eric Weinstein's Geometric Unity (GU) proposes a 14-dimensional geometric framework intended to recover general relativity and the Standard Model from a single construction on an "observerse." Public presentations and the 2021 working draft leave critical elements incomplete: the definition and uniqueness of the Shiab contraction, compatibility of anomaly cancellation with the structure group required for that contraction, a fully specified classical action, and a controlled reduction to four-dimensional physics.
