The Unified Theory of Informational Spin (TGU) proposes a reformulation of physical reality in which information—organized into coherent patterns termed informational spin—is treated as a fundamental organizing substrate. Within this framework, gravitational phenomena are interpreted as emergent effects of informational coherence gradients, offering an alternative description to conventional mass–energy-based formulations. TGU aims to unify general relativity, quantum mechanics, biological systems, and computational science under a single coherence-centered paradigm. The model introduces a phenomenological correction factor for orbital dynamics, α = 1 + k ·e/a, where the Matuchaki Parameter k ≈ 0.0881 arises from geometric considerations related to the normalization of a three-dimensional coherent spin field. Numerical implementations of this correction demonstrate convergence with general relativistic predictions in weak-field regimes and generate distinctive deviations in high-strain or highly eccentric systems. Across multiple domains, TGU provides a coherent interpretative framework capable of reproducing known orbital precession results, modeling galactic rotation behavior without invoking additional matter components, and generating testable predictions for cosmological observations, condensed-matter systems, and biological information processing. Rather than treating gravity as purely geometric curvature, TGU reframes it as an informational effect governed by coherence dynamics, positioning informational coherence as a unifying principle underlying physical, biological, and computational phenomena.
