Dark Matter Aggregation, Critical Threshold and Transformation into Visible Celestial Bodies——Also on Dark Matter Enrichment at Gravitational Lens Foci

Dark matter constitutes the major part of the mass-energy in the universe, yet its nature remains unresolved. The First-Principle Unified Theory of Light Strings has identified dark matter as a proton–two-electron axially symmetric composite: a proton (trefoil knot) at the center, with two electron rings symmetrically arranged on opposite sides, parallel ring planes, and opposite spins. This structure is completely electromagnetically shielded, absolutely stable, and interacts only gravitationally. Building on this foundation, this paper provides a first-principles derivation of the aggregation process of dark matter, the formation of dark matter halos, substructure collapse, the pressure threshold, and the structural phase transition. It is shown that when a dark matter clump exceeds the critical pressure, it transforms into ordinary matter (neutrons, free electrons, protons) and subsequently forms visible celestial bodies. In particular, this paper proposes that the phase transition exhibits a chain‑reaction nature, with energy release growing exponentially. A sufficiently massive dark matter clump crossing the threshold may trigger a supernova explosion, offering a new physical explanation for certain types of supernovae. The paper also predicts that the gravitational lens foci of celestial bodies are natural regions of dark matter enrichment, and it strictly distinguishes between two scenarios: dynamical dilute enrichment and self‑gravitating compact clumps. It is clarified that dark matter at the focus of ordinary stars does not disintegrate, whereas massive pure dark matter clumps can undergo chain reactions under self‑gravity. The entire reasoning is logically closed, consistent with the established axioms of the light string theory, and provides several testable observational predictions.
