Emergent Gravity in Resonant Bubble Cosmology: Lagrangian Derivation and the Low-Acceleration Regime

In Resonant Bubble Cosmology gravity emerges from a fermionic condensate rather than being fundamental. The bulk Lagrangian on four-dimensional Euclidean space is written explicitly, and its two dimensional transmutations are verified to high precision. Newton’s constant is computed from first principles. Below the acceleration scale a₀ the weak equivalence principle must break, and inertia arises as the medium’s drag (the Viscosity of Lorisa). The model derives the evolution of a₀ with redshift and reproduces the Baryonic Tully-Fisher relation while satisfying all classical gravitational tests without additional screening mechanisms.
