A scientific paper titled "Unified Theory," written by independent researcher Marco Saba, proposes an extended $f(R,z)$ gravity model to explain anomalies observed by the James Webb Space Telescope (JWST), such as the unexpectedly massive galaxies in the early universe. The author introduces the concept of a "supergraviton" as a dynamic scalar field that bridges classical gravity and quantum effects, providing complete mathematical derivations and a rigorous statistical analysis that strongly favors his model over the standard $\Lambda$CDM model.
