Spacetime Fluid v2. 0: T_μν Unifies 16 Orders (9-0 vs ΛCDM)

Key Points

• The study aims to present a unified model of spacetime as a superfluid that explains gravity and cosmic structures with fewer parameters.
• Developed a spacetime model characterized as a superfluid medium.
• Determined universal density and its constraints from cosmic background radiation.
• Performed hydrodynamic analysis to recover general relativity predictions.
• Assessed the model's performance against existing galactic and cluster data using chi-squared testing.
• The new model fits galactic and cluster data with a chi-squared per degrees of freedom of 0.001, outperforming ΛCDM.
• Gravity is described through displacement pressure gradients based on baryonic mass.
• A significant reduction in parameters from 26 (GR+ΛCDM) to one physical principle is achieved.
