This paper proposes a structural reinterpretation of non-existence. Rather than representing absolute absence, non-existence is understood as the domain of unrealized possibilities within a broader possibility space. Using a formal framework grounded in set theory and dynamic systems, the model describes how new structures emerge from unrealized possibilities through exploration, evaluation, and stability constraints. The framework connects ontological structure with processes observed in biological evolution, scientific discovery, technological innovation, and artificial intelligence. The paper's central contribution is a formal account of structured discovery through impossibility. When a target configuration appears impossible, that impossibility is not a terminal condition but a structured object of analysis: it marks a specific location in possibility space, bounded by identifiable constraints that may be contingent rather than absolute. This analysis is formalized through Impossible-First Reasoning (IFR), a three-stage discovery method in which radical imagination reveals constraint structure, constraint identification locates the boundary, and structural reframing — drawing on the Unification Method — reorganizes the generative conditions that produce the constraint. A worked historical case demonstrates the methodology. The paper also identifies interpretive mappings between the mathematical framework and the Trinity Framework of Cognitive Systems. The Trinity Framework served as the motivating context from which IFR was originally developed; the formal framework developed here now provides independent mathematical grounding for those cognitive structures. The formal framework stands independently of the Trinity Framework and does not require it for validation.
