SACCADE: A Structural Unification Model for Cross-Scale System Formation and Evolution

SACCADE is a structural unification model that identifies a single developmental architecture governing how systems form, stabilize, adapt, and evolve across cosmic, planetary, biological, neural, cognitive, and social scales. Although the mechanisms in these domains differ, their organization follows the same seven-stage sequence—Signal → Arrival → Context → Constraint → Adaptation → Distribution → Evolution—which describes how systems capture energy, build stabilizing structures, establish pathways, and reorganize under changing conditions.

This work does not propose new physical or biological mechanisms. Instead, it reorganizes well-established empirical findings into a shared structural ontology that reveals deep cross-scale homologies in system formation. By integrating results from cosmology, geophysics, evolutionary biology, neuroscience, psychology, and social theory, the SACCADE model demonstrates that stability is always a slow-forming, constraint-centered process, while energy and change propagate rapidly along pathways shaped by those constraints.

SACCADE contributes a unified developmental logic for interpreting how systems learn, persist, fracture, and transform over time. It also provides a method for cross-domain reasoning based on structural equivalence rather than metaphor, enabling insights from one field to illuminate analogous constraints, pathways, and stability dynamics in another.
