Elemental Transformation Principle（ETP）

This paper proposes the Elemental Transformation Principle (ETP) as a universal causal law governing the evolution of matter across cosmic scales. From atomic nuclei to galactic structures, we argue that the transformation of elements through fusion, decay, and structural reconfiguration serves as the recursive engine behind entropy redistribution, systemic evolution, and complexity emergence. We formalize this principle through a general transformation function that accounts for local physical variables—pressure, temperature, density, and external flux—as well as recursive feedback loops operating at stellar, planetary, and symbolic levels. Special emphasis is placed on stellar evolution chains, supernova feedback, black hole collapse, and intelligent manipulation of matter. By embedding ETP within a broader Universal Causal Systems Theory, we demonstrate that the transformation of elements is not merely a chemical or astrophysical process but a fundamental mechanism by which the universe encodes, stores, and transmits causality itself. This perspective repositions matter as a recursive causal substrate, integral to the architecture of long-term cosmic dynamics and the potential constraints of the Great Filter.
