Hydraulic Pressure Dynamics: A Mechanical Interpretation of Cosmic Expansion and its Inconsistencies

This paper introduces a mechanical interpretation of cosmic expansion, moving away from abstract mathematical models toward a unified hydraulic system framework. By re-evaluating the Hubble Tension as a manifestation of fluid density variations rather than an independent expansion phenomenon, we propose that cosmic phenomena are governed by pressure dynamics and vortex stability within a cosmic superfluid. This research offers an alternative to dark energy hypotheses, suggesting that material mechanics, rather than fluctuating constants, provide the foundational laws of the universe.
