Black Holes as Temporal Mediation Boundaries: Why Interior Ontology Is a Category Error

Black holes are commonly discussed in terms of their interior contents, giving rise to persistent paradoxes concerning matter destruction, information loss, and the fate of infalling observers. Despite extensive theoretical development, such questions remain unresolved, suggesting that the difficulty lies not in missing physics but in a category error in how black holes are described. This work argues that a black hole is best understood as a regime boundary at which the temporal resolution required to individuate matter irreversibly fails. Matter does not transform or persist beyond this boundary; rather, it ceases to be a valid descriptive category. What remains admissible are boundary-accessible observables such as fields, modes, conserved quantities, lensing, radiation, and accretion dynamics. By reframing black holes as limits of temporal mediation rather than objects with interior ontologies, familiar paradoxes dissolve without invoking new physics or speculative mechanisms. This paper is interpretive and classificatory in scope, clarifying the descriptive domain in which matter-based language applies and why interior narratives are structurally ill-posed.
