Emergent Spacetime

This work presents a non-fundamental treatment of spacetime within a correlational framework in which physical reality is described as an open correlational structure without primitive space, time, or dynamics. At the ontological level, the correlational substrate is shown to be non-spatiotemporal, admitting neither localization nor temporal ordering. Spacetime is derived as a regime-dependent descriptive structure that emerges only when spatial and temporal projections are simultaneously admissible and mutually compatible. Spatial relations arise from projection-induced relational separation, while temporal ordering arises from persistent ordering relations. Spacetime appears exclusively in regimes where both structures coexist and remain stable under admissible perturbations. Metric structure, causal ordering, locality, and light-cone behavior are identified as effective, projection-induced features rather than fundamental properties. Static and ordered spacetime regimes are classified, and their relation to gravitational and propagating descriptions is clarified without introducing ontological spacetime dynamics. The analysis delineates the precise conditions under which spacetime descriptions are valid and the regimes in which they must break down. By separating descriptive spacetime structure from fundamental correlational ontology, the framework provides a conceptually economical account of space, time, and their joint emergence in physical theory.
