The NavMesh Cosmology: Resolving the Vacuum Catastrophe, the Hubble Tension, and Deriving the Absolute Baryonic Mass of the Universe via Computational Spatial Friction

Abstract

The ΛCDM framework faces two major crises: the Hubble Tension and the 10¹²² Vacuum Catastrophe. We present The NavMesh Cosmology, a parameter-free discrete geometric framework modeling the universe as a spatial lattice where time emerges exclusively from structural friction, eliminating the need for Dark Matter or Dark Energy. By analyzing 55,877 macroscopic observations from the Cosmicflows-4 database, we employ a 3D KD-Tree collision algorithm to map local baryonic data density. Defining baryonic mass as computational latency, we formulate a deterministic prediction engine: H = H_base / √D. Tested against raw data, this model predicts galactic velocities with a correlation of R = 0.9039 and an unfiltered variance of R² = 0.8170. Furthermore, we isolate the universal Slowdown Ratio (S_r ≈ 7.69 × 10⁶⁰) by dividing the theoretical maximum processing speed (Planck frequency) by the macroscopic rendering rate (H₀). We demonstrate that the 10¹²² Vacuum Catastrophe is purely a geometric deceleration artifact. Equating S_r directly with the spatial continuum's informational capacity limit (the Planck mass), we deterministically derive the total absolute baryonic mass of the observable universe as 1.67 × 10⁵³ kg. This yields an exact match with Big Bang Nucleosynthesis (BBN) estimates, proving the universe operates as a closed, parameter-free computational manifold.
