The Theory of Informational Spin: A Coherence-Based Framework for Gravitation, Cosmology, and Quantum Systems

We present the Theory of Informational Spin (TGU) as a coherence-based, phenomenological extension of General Relativity designed to operate consistently across gravitational regimes. Rather than replacing relativistic gravity, the framework preserves full convergence with General Relativity in weakand intermediate-field domains while allowing for controlled, scale-dependent deviations in systems characterized by high orbital strain or structural asymmetry. In the TGU formalism, gravitational dynamics acquire an effective contribution associated with gradients of informational coherence, encoded through a dimensionless coherence efficiency factor—the Matuchaki parameter—derived from geometric normalization arguments rather than empirical fitting. This construction introduces no additional particle species and does not increase the number of freely tunable degrees of freedom once fixed. We demonstrate cross-regime consistency by applying the same coherence parameter to both orbital and galactic-scale phenomena. At Solar System and Galactic Center scales, including the S2 star orbit around Sagittarius A*, the theory reproduces General Relativity to observational accuracy, consistent with current high-precision astrometric constraints. At galactic scales, flat rotation curves can emerge as effective consequences of coherence geometry alone, without invoking dark matter components. The framework further yields clear, falsifiable predictions for high-eccentricity or compact systems, strong-field orbital configurations, gravitational-wave polarization, and coherence-sensitive laboratory experiments. Together, these results position the Theory of Informational Spin as a conservative, testable extension of relativistic gravity, offering a unified phenomenological description of gravitational dynamics across multiple physical scales while remaining fully compatible with existing observational data.
