Marabūt's Theory of Gravity: Empirical Validation of the Electron Flow Model

This manuscript presents a rigorous empirical validation of the Electron Flow Model (EFM) against the Pantheon+ Type Ia Supernova Catalog. By directly confronting the EFM’s Viscous Propagation Integral with the full set of 1,701 distance moduli, we demonstrate that the model natively reproduces observed luminosity-distance curves. Using formal Bayesian Markov Chain Monte Carlo (MCMC) methods, this empirical confrontation establishes the robust predictive capabilities of the EFM, demonstrating that astrophysical phenomena can be natively reproduced without dependence on unverified theoretical placeholders. By anchoring the matter density to the independently measured baryonic fraction (Ωm = 0.051), the model aligns with observations without requiring a cosmological constant or dark energy. The best-fit parameters are H0 = 69.67 km/s/Mpc and τvac = 2.78. The analysis also provides a fluid-dynamic interpretation of the Hubble Tension, presenting it as a natural result of localized variations in the vacuum pressure gradient. The Unified Fluid Cosmos Framework: This paper serves as Manuscript 16 Version 1 in the comprehensive series, Marabūt's Theory of Gravity. It presents the Electron Flow Model (EFM), a generative, fluid-dynamic framework designed to fundamentally replace Albert Einstein's General Relativity and standard Quantum Mechanics. The EFM shatters classical circularity with a single, undeniable foundational premise: Gravity is Pressure, not curvature, and not an intrinsic mass property.
