- We present a modified gravity framework where the vacuum is modeled as a Higgs-type scalar field $χ$ undergoing spontaneous symmetry breaking. By introducing a coupling $Q^ν= αT \nabla^νχ$, we formalize a displacement principle where baryonic matter acts as an impurity in the vacuum substrate. This interaction leads to a restorative buoyancy force that modifies the geodesic equation and violates the Weak Equivalence Principle. We show that this mechanism naturally recovers the Schwarzschild metric in the vacuum limit while providing a Yukawa-corrected Newtonian potential in the presence of matter. This correction offers a dynamical explanation for flat galactic rotation curves and a tracking mechanism for the cosmological constant, potentially resolving the coincidence and fine-tuning problems without the need of dark sectors.
