Disappearance as a Possible Manifestation of V₀: Consistency and Testability Conditions for a Hypothesis of Controlled Termination of Shared Physical Realization

Abstract

This preprint analyzes a hypothesis according to which a specially controlled change of a body's physical state could terminate its shared physical realization with our world while preserving the body's internal structure, and asks whether such an outcome could be attributed specifically to V₀. Here V₀ denotes absolute nothingness with no physical or structural properties, spatial location, or causal role; it is not treated as a medium, reservoir, container, state, or destination. Operational non-detection, loss of specified external links, and the stronger hypothesis of termination of shared physical realization are distinguished. The paper formalizes natural and controlled histories, a pre-specified matching of physical stages, multi-component discrepancies, and typed opposition to a natural tendency. Six conditional results are established: zero net force does not imply loss of interactions; feasible control does not imply the transition; switching off a single coupling does not determine ontology; within models on a shared smooth spacetime and without an additional singular surface term, distributional conservation imposes a jump condition on the stress-energy tensor; a signal received after a claimed event need not have been generated after it; and identical observable-data laws make V₀ attribution statistically indistinguishable in the chosen observation language. No concrete physical characteristic, critical regime, or transition law is established. The paper reports neither observed disappearance nor a demonstrated mechanism or proof of V₀; its contribution is a self-contained test architecture and a minimal specification of the next empirical step.
