Empirical Evidence for Entropy-Stabilized Dynamics:\\ Galactic, Cosmological, and Quantum Results under the TEQ Framework

The Total Entropic Quantity (TEQ) framework derives quantum, gravitational, and cosmological structure from the stationarity of an entropy-weighted effective action. Here, we examine the empirical validity of TEQ across five distinct empirical settings, grouped into three broad physical domains: galactic dynamics, cosmic evolution, and quantum measurement. Specifically, we show that: (1) the Baryonic Tully–Fisher relation and flat galactic rotation curves follow from entropy curvature constraints in galaxy outskirts; (2) the TEQ-predicted peak in cosmic entropy realization aligns with recent DESI observations of a declining dark energy driver; (3) deterministic suppression of interference patterns in DPIM (Deterministic Photon Interaction Model) experiments arises from entropy-weighted path selection under measurement-induced entropy gradients; (4) quantum eraser experiments exhibit observer-dependent entropy modulation of interference, consistent with TEQ predictions; and (5) quantum decoherence experiments (such as cavity QED) provide direct evidence for continuous suppression of interference under increasing measurement coupling; a behavior structurally explained in TEQ as entropy-stabilized contraction of path ensembles. These results provide multi-scale empirical support for TEQ and motivate further investigation of entropy geometry as a fundamental organizing principle in physics.
