Vacuum as an Observational Medium: An Epistemically Conservative Framework for Cross-Domain Correlation
Zero-Transit is a foundational research program asking whether synchronized, heterogeneous precision measurements can reveal reproducible cross-domain correlations that are not adequately explained by known natural, instrumental, environmental, or human causes. This paper defines the “vacuum as an observational medium” as a research proposition rather than an established physical mechanism. It separates observation from interpretation, specifies an explicit null hierarchy, and proposes a reversible correlation architecture in which raw data remain immutable while contextual and hypothesis layers can be added or removed. Quantum field theory provides experimentally established evidence that the vacuum is not an empty classical background, but neither Casimir-force measurements nor theoretical vacuum entanglement establish a usable long-range information channel. The Zero-Transit pathway therefore begins with measurement discipline and falsification rather than mechanism selection. The paper describes measurement families, timing requirements, statistical controls, evidence gates, and advancement criteria suitable for testing the proposition without manufacturing anomalies through irreversible filtering.
