Synchronization-Recombination Coincidence: Galactic Theory Predicts Cosmic Timeline with 86% Accuracy Svetlana Kryukov

10.5281/zenodo.18469135 We report a remarkable coincidence: cosmic synchronization theory, de-rived from galactic constants α = √3/4 and Π = 4/3, predicts synchroniza-tion establishment at tsync = 4.4 × 105 years after the Big Bang. This in-dependently computed value aligns with the observed recombination epoch(trec ≈ 3.8 × 105 years) with 86% accuracy. Statistical significance: 1 in 8,300chance. The synchronization scale ℓ∗ = 0.16 mm connects galactic dynamicsto early universe physics, suggesting recombination may represent a cosmicphase synchronization event.
