The Macro-Neutron Conjecture: Modeling Black Hole Singularities as Structurally Saturated Acoustic Droplets

Standard cosmological models utilizing General Relativity provide a profound and highly predictive geometric map of spacetime curvature. Building upon this elegant mathematical foundation, this paper introduces a complementary mechanical framework by modeling the spatial medium as a continuous, load-bearing fluid lattice. Within this continuum approach, physical structures are treated as scale-invariant entities governed by fluid dynamics and structural yield limits. We introduce the 'Macro-Neutron Conjecture,' which conceptualizes the core of a black hole as a structurally saturated acoustic droplet existing in perfect hydrostatic equilibrium. Drawing mechanical parallels to subatomic electron capture, we model extreme gravitational compression as a state where the thermodynamic boundary layer (the region of reactive shear stress) merges entirely into the hydrostatic core. Consequently, the core operates as a neutral, unreactive anchor, while the event horizon functions mechanically as a continuum shear boundary responsible for thermodynamic exhaust. By defining the black hole core as a state of perfect vector equilibrium, this model forces the natural frequency (ν) of internal thermodynamic cycles to drop to zero, providing a localized, fluid-dynamic complement to gravitational time dilation. This smoothly unites the structural rules of quantum mechanics and astrophysics into a deterministic, testable foundation.
