The Moon as an Ontological Threshold. On the Boundary of Immanence and the Forgotten Knowledge of Verticality

This article proposes an expanded ontological analysis of the Moon by reintegrating traditional forms of knowledge—particularly Vedic cosmology—in which the Moon is understood as a threshold space between the temporal physical world and a non-temporal, etheric level of being. It is demonstrated that the liminal nature of the Moon was known to humanity since antiquity but was entirely excluded from the methodological framework of 20th-century lunar missions, including the Apollo program. On this basis, the paper advances the thesis that a purely technical approach to threshold cosmic environments is ontologically incomplete and intrinsically risky. The article culminates in the formulation of a rigorous ontological criterion for admissible lunar missions grounded in epistemic proportionality rather than technological capability alone.
