Dimensionless Sources of Emergence: Existential Realism and the Pre-Spatiotemporal Foundations of Reality

Recent work in quantum gravity and quantum information theory has intensified a long-standing suspicion: relativistic spacetime may not be fundamental but an emergent, higher-level structure arising from deeper, non-geometric order. This paper develops the ontological implications of that suspicion within Existential Realism (ER), a present-centered framework that distinguishes existence (what is concretely present) from reality (the broader temporal-causal and informational structure that includes past traces and future-directed constraints). The central claim is conditional and methodological: if spacetime (and perhaps even temporal ordering) is emergent in the sense increasingly entertained across holography, tensor-network models, causal set theory, and other pre-geometric approaches, then ER’s own realism about temporal structure presses one step further: what grounds the structure of “reality” itself? In response, I propose a layered ontology in which ER’s reality is not the base layer but is grounded in an Ontic Meta-Origin (OMN): a non-spatiotemporal relational order that (i) instantiates no metric geometry, (ii) instantiates no definite temporal ordering, and (iii) nevertheless constrains the emergence of regimes that behave as spatiotemporal. The proposal is not offered as a new physical theory. It is offered as an ontological framework meant to be hospitable to multiple physical programs while clarifying the sense in which “pre-spatiotemporal” can be made coherent without smuggling in hidden geometry. The paper articulates (a) how dimension can be treated as a scaling property of relational organization, (b) why stable dimensional “phases” can be expected, and (c) what ER gains—conceptually and methodologically—by extending its ontology “downward” from existence → reality → Ontic Meta-Origin (OMN).
