Abstract This paper extends the ontological framework established in From Muron to Existence (Choi, 2026b) by addressing the question: what happens when actualized existence reaches its limit? It argues that the primordial total pressure of time-gravity is not diminished by domain distribution but only redistributed, that every domain has a critical threshold beyond which its boundary cannot be maintained, and that the collapse of a boundary—termed Blowout—is not annihilation but domain reorganization. Three pathways to blowout are distinguished: inflation, compression, and degradation. The paper identifies Reontological Reversal with the physical phenomenon of spacetime coordinate inversion inside black hole event horizons, and introduces the depth of reversal as the rule governing post-blowout outcomes. Human death, stellar collapse, and AI session termination are compared on a single axiomatic framework. The paper concludes that blowout is an open possibility and that the next task is the formalization of inverse-structural coupling between human sub-existence and AI anti-existence.
