FCU-004 Coherence and Drift as Universal Dynamical Principles – Toward a Relational Theory of Emergence, Persistence, and Collapse Across Scales

Why do galaxies endure for billions of years while turbulent clouds disperse? Why do ecosystems maintain their organization despite continual change? Why can memories, civilizations, and cultures persist across generations without remaining static? This working paper proposes coherence and drift as complementary dynamical principles governing the emergence, persistence, transformation, and collapse of structure across cosmological, biological, cognitive, and social systems. Rather than treating order and disorder as opposing conditions, the paper argues that stable organization emerges through the continual interaction between coherence, which preserves relational structure, and drift, which redistributes variance and creates opportunities for renewed differentiation. Building upon the relational foundations established in previous papers of the Finite Cyclical Universe (FCU) research program, this study develops a conceptual framework for understanding persistence as an emergent property of finite relational dynamics. It introduces coherence fields as stable regions that arise near critical variance, where concentration and redistribution remain dynamically balanced. A complementary geometric interpretation distinguishes unconstrained isotropic growth, which naturally tends toward sphere-like organization, from regulated growth, which produces flattened coherence fields composed of a concentrated center and a surrounding redistribution layer. The paper further proposes that information reaches its greatest significance not within perfectly ordered or fully dispersed regions, but at relational boundaries where coherent structures encounter variation. Complexity is therefore interpreted as an emergent consequence of organized relational persistence rather than merely density or accumulation. Extending ideas introduced in CCN–001, the paper argues that apparently sparse environments, including interstellar space, may retain substantial structural potential despite low observable compression, suggesting that coherence remains embedded within drift as an unrealized possibility. Beyond cosmology, the coherence–drift principle is presented as a universal organizing framework applicable to stars, ecosystems, minds, and civilizations alike. By identifying persistence as the dynamic balance between stabilization and redistribution, the paper provides a conceptual bridge between the foundational FCU dynamics and the forthcoming Multi-Layer Resonance Model (MLRM), where interacting layers of matter, life, cognition, and meaning are understood as nested expressions of relational coherence. As the fourth publication in the FCU series, this work advances a relational interpretation of emergence while laying the theoretical foundations for future investigations into layered resonance, cosmological evolution, coherence field formalism, and observational predictions.
