The Ontology of Gravitation: Long-Range Constraint Gradients and the Curvature of Reachability

What is gravity? Newton saw it as an instantaneous force acting at a distance. Einstein re-envisioned it as the curvature of spacetime. In Energy-Efficiency Theory (EET), gravitation is neither a fundamental force nor a primitive geometric field, but a derived, emergent phenomenon: \textbf{the long-range gradient of the total constrained potential $\mathcal{U}(\mathbf{r})$ across the constraint network}. This paper develops the complete ontology of gravitation from the generative foundations of EET Core Rules v5.2 and the companion ontologies of Constraint, Space, and Mass. At L1, gravitation is defined by two complementary manifestations: 1. Gravitational Force: The response of a constrained-state node (mass)…
