"The Unified SDD Model: Solving the Hubble Tension through the 1:137 Stability Ratio and Space-Density Constant (k=0.256)"

Overview: This research introduces the 1:137 Stability Ratio, a breakthrough mathematical framework within the Space-Density Displacement (SDD) Model. It provides a novel solution to the "Hubble Tension" by redefining galactic stability through a universal density constant k=0.256. Key Highlights: The 137 Law: Establishes that galactic integrity is maintained when the ratio between internal displacement forces and cosmic expansion aligns with the Fine Structure Constant. Beyond Dark Matter: Offers a physical explanation for galactic rotation curves, potentially replacing the need for undetected dark matter particles. Scientific Interest: This updated version (V12.0) incorporates advanced stability derivations following broad engagement and review of previous versions by the global research community.
