This research report presents the Space-Density Displacement (SDD) Model Version 9.0, offering a revolutionary physical foundation for the origin and expansion of the universe. Moving beyond the single singularity of the Big Bang, this model demonstrates a Multi-Point Origin where mass is simultaneously emitted as "Mass Webs" from Black Holes—points of total spatial displacement. Key Highlights of SDD Model v9.0: Solving the Hubble Tension: Provides a concrete solution to the expansion rate discrepancy through the Law of Spatial Interchange. JWST Alignment: Explains the existence of mature, early-stage galaxies observed by the James Webb Space Telescope through global, simultaneous web emission and collision. Mass-Space Consistency: Proposes that Black Holes are formed when space properties are fully displaced, aligning with atomic-scale void principles. High Statistical Correlation: Demonstrates a correlation coefficient of r=0.945 (over 90%) with current galactic distribution data. Dark Energy Alternative: Argues that universal expansion is driven by physical space displacement and mass-web emission rather than hypothetical Dark Energy.
