For the last two years (2025-2026), the most exciting "new physics" has applied Sternberg’s extension theory to the ** asymptotic symmetry groups of spacetime**.
In early 2026, a collaboration between the Perimeter Institute and Harvard (building on Sternberg’s final notes) showed that the BMS group must be via a Sternberg cocycle. The result? The infinities disappear. Moreover, the extended group predicts a new massless particle—a "soft graviton" with specific polarization properties that match the yet-to-be-confirmed high-energy anomalies observed in LHC ultra-peripheral collisions.
