Cosmic Ingestion in T-M-R Theory: Stabilization of Radioactive Isotopes via Dark Matter Accretion

The Time-Mass-Radius (T-M-R) Theory proposes that all physical bodies, down to the atomic nucleus, are geometrically coupled to a background field of dark matter. We introduce the "Cosmic Ingestion" postulate: matter accretes at a rate proportional to surface area and local dark matter density. As a direct consequence, unstable nuclei experience a time-dependent stabilization. Over cosmological timescales, this ingestion can suppress decay channels and lead to the synthesis of heavier elements. We derive the ingestion rate, the modified half-life equation, and provide order-of-magnitude estimates. This mechanism offers testable predictions for isotopic abundances in ancient geological samples and links T-M-R to observed nuclear stability.
