Superfluid Vacuum Model: A Unified Hydrodynamic Synthesis of Dark Matter, Quantum Discreteness, and Gravitational Fluctuations

The standard cosmological model (CDM) relies on the existence of dark matter to explain large-scale gravitational anomalies. However, the continued failure to directly detect dark matter particles suggests a fundamental deficiency in our understanding of vacuum dynamics. This paper proposes a "Superfluid Vacuum Model" (SVM) as a self-consistent alternative. By treating the vacuum as a nonlinear, viscous superfluid medium rather than a static empty space, this model provides a unified framework to explain galactic rotation curves, gravitational lensing, and cosmic microwave background (CMB) acoustic oscillations. The SVM approach aims to minimize the complexity of the current cosmological model by demonstrating that observed anomalies can be resolved through inherent fluid-dynamic interactions of the vacuum itself.
