A Rheological Approach to the Viscous Fermionic Vacuum Condensate. Part IV. Relativistic Pericenter Precession of Mercury via ψ-Condensate Drag

This paper demonstrates that the anomalous perihelion precession of Mercury (∆Φ ≈ 43" per century) emerges naturally from the hydrodynamic interaction between a baryonic defect and the physical vacuum, modeled as a viscous fermionic condensate (VFC). By modifying the classical Binet equation to include the rheological momentum dispersion tensor of the medium, we derive the exact analytical expression for the secular shift without resorting to the geometric abstractions of general relativity. The calculated precession of 42.98′′ per century is in exceptional agreement with empirical observational data.
