The Unified Fluid Cosmos Community (UFCC) serves as the official academic and open-source computational hub for the Electron Flow Model (EFM). Moving beyond the limitations of General Relativity, the EFM formally establishes that "Gravity is Pressure". By modeling gravity as hydrodynamic fluid pressure driven by multiaxial vacuum flux, this framework systematically maps celestial mechanics across 11 distinct Mara Levels, entirely eliminating the reliance on mathematical singularities or dark matter. This community repository permanently archives the comprehensive 35-Manuscript Theoretical Foundation, the Grand Computational Atlas, and the Python-based EFM Volumetric Profiler toolkits.
