BECU–OLON: A Geometry-Driven Framework for Cosmology

The BECU–OLON framework presents a geometry-driven approach to cosmology in which gravitational dynamics emerge from the structural properties of baryonic matter. The theory is developed across a sequence of works that together establish a coherent and testable description of physical behavior across scales. At the observational level, the framework demonstrates consistency with key cosmological probes, including structure growth, cosmic microwave background anisotropies, and gravitational lensing, while preserving early-universe physics and introducing controlled late-time modifications. At the structural level, a single dimensionless parameter governs the dynamical response and consistently separates distinct physical regimes across independent systems. At the theoretical level, a critical value naturally emerges from stability considerations, defining the transition between these regimes without the need for phenomenological tuning. Taken together, the results indicate that gravitational behavior can be understood as a geometric response to matter distribution, providing a unified framework that connects galaxy-scale dynamics with cosmological observations within a single formulation.
