Legacy physics relies on geometric abstractions to describe stellar collapse. This paper outlines the true mechanical engine of stellar evolution using the Electron Flow Model (EFM). By contrasting legacy models with EFM mechanics, we define the cause of supernovae, Electron Void Gravitational Spheres (EVGS), the ultimate thermodynamic sink of unbuffered protons, and high-density pulsars. EVGS are traditionally known as Black Holes. Addressing the traditional boundaries of the Standard Model, we mathematically demonstrate that the stellar core undergoes a rapid geometric realignment driven by fluid-dynamic pressure, rather than a passive gravitational crush. To validate this framework, we provide a falsifiable prediction regarding micro-stutter Gravitational Wave (GW) signatures unique to mechanical lattice failure. Foundational Mathematical Framework and Primary Theory: https://doi.org/10.5281/zenodo.20126552 The Unified Fluid Cosmos Framework: For over three centuries, dating back to Sir Isaac Newton, astrophysics has treated gravity as a static, geometric given. While Albert Einstein's General Relativity excels at calculating orbital mechanics, effectively teaching us how to drive the car, it relies on an epistemological circularity, retroactively assigning invisible mass to force its equations to fit observations. It offers no physical insight into how the engine actually works. This paper serves as Manuscript 4 Version 4 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 General Relativity. The EFM shatters classical circularity with a single, undeniable foundational premise: Gravity is Pressure, not curvature, and not an intrinsic mass property.
