Marabūt's Theory of Gravity: Resolving the CMB Power Spectrum

In standard cosmology, the amplitude ratios of the Cosmic Microwave Background (CMB) acoustic peaks are cited as the definitive proof of Dark Matter. The classical framework assumes that invisible mass creates gravitational potential wells, which drive the compression of the primordial plasma to form the third acoustic peak. Following the mathematical derivation of the comoving Sound Horizon in Manuscript 17, this paper applies the locked Volumetric Mara Compression constant (₌₀ₑ₀ = 2. 2895 10^-4) to the complete CMB power spectrum. We demonstrate that when the Vacuum Flux is treated as a continuous ultra-relativistic fluid, the structural bulk modulus of the medium itself serves as the exact restoring force required to generate the acoustic peak amplitudes natively. By successfully predicting the primary, secondary, and tertiary peak ratios (2. 40 and 2. 15 respectively) strictly using observable Baryonic Density (ₘ = 0. 051) and Structural Fluid Impedance, the Electron Flow Model (EFM) definitively eradicates the requirement for Dark Matter potential wells in the early universe. Furthermore, Silk Damping is mechanically resolved as the inherent shear viscosity of the electron medium transitioning across the photon decoupling boundary. The Unified Fluid Cosmos Framework: This paper serves as Manuscript 18 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.
