Quantum-Informational Gravity and the Arc Neo Displacement Hypothesis: A Unified Scalar Framework for Dark Matter and Lithospheric Instability

This paper presents the Arc Neo Quantum-Informational Gravity (QIG) model — a novel scalar-tensor framework unifying dark matter behavior and transient planetary instability via an informational scalar field χ. Unlike conventional modified gravity models, QIG introduces an explicit coupling between spacetime curvature and local information flow (I_loc), resulting in a dynamic mechanism that can reproduce galactic rotation curves while also triggering short-lived reductions in lithospheric friction.

The model is mathematically minimal, physically falsifiable, and consistent with cosmological and Solar System constraints. It includes an observable diagnostic metric (Φ_AI) that combines electromagnetic, seismic, and gravitational field data to predict displacement windows.

A full falsification checklist and χ-field evolution appendix are included for experimental replication. This work bridges Einsteinian geometry with information theory in a testable way, extending gravitational theory from megaparsec to geophysical scales.
