Towards a Theory of Physical Law Selection

This paper develops the hypothesis that the fundamental constants and symmetry structures governing physicsare not arbitrary fixed parameters, but the result of a selection process operating across successive cosmologicalcycles. The proposed mechanism localises hereditary variation in the quantum decoherence occurring duringspontaneous symmetry breaking in the primordial universe. The theory produces a hierarchical testable prediction : the robustness of fundamental constants should be positively correlated with the chronological age of the symmetry-breaking event that fixed them. This prediction is confronted with existing data on the strong coupling constant, the cosmological constant, and measurements of fine-structure constant variation in distantquasar spectra. The epistemological limits of the hypothesis are explicitly formulated.
