Dilatant Dark Fluid: Toward a Unified Quantum-Hydrodynamic Origin of Lorentz Invariance, Gravity, and Cosmological Phenomenology

This work introduces the dilatant dark fluid (DDF), a pervasive cosmic cold dark medium comprising two coupled ultralight bosonic sectors: a superfluid \(\phi\) and a heavier dispersed phase \(\varphi\) undergoing stress-induced shear jamming, distinguishing the framework from ea...
