A Unified Equation for Chronogravity: Emergent Gravity from Time Dilation Buoyancy

This paper serves as a reader's guide to the Chronogravity series, introducing a unified equation that captures the framework's essence: gravity emerging as buoyancy in a fifth-dimensional ψ-field from time dilation gradients. The equation, inspired by mass-energy equivalence (E=mc²), derives from the model's 5D master action upon compactification and recovers Newtonian gravity while allowing topological modifications (e.g., log(r) terms for flat rotation curves without dark matter). We explain the equation's components, provide a comprehensive table of key symbols, and discuss implications for unification, dark matter alternatives, testable predictions (GW birefringence, warp signatures), and open questions (QFT reduction, biological extensions). This work synthesizes the 24-preprint series, offering an accessible entry point for exploring Chronogravity's emergent paradigm. Open-access preprint – feedback and collaboration welcome.
