Fluctuating Baryonic Field – Phase 2: Energetic Extension, Confinement, and Universal Expansion

This work presents the second phase of the Fluctuating Baryonic Field model,which extends the original formulation by introducing the energetic couplingbetween baryonic matter and its radiative environment.The model explores how energy confined within the baryonic field can be releasedthrough structural loss, producing effective negative pressure and drivinglarge-scale expansion without the need for exotic dark components.The same formalism also describes confinement processes near event horizons.Numerical results, obtained using the SPARC galactic rotation databaseand the Fermi 4FGL energetic catalogue, confirm the stability and coherenceof the field equations under parameter variations.This phase establishes the theoretical and observational foundation for subsequent extensionsof the model toward cosmological regimes.
