Negative-Grounded Cosmology: A Münchhausen-Stable System with Loop Closure and Substrate-Independent Identity

This paper presents a cosmological-epistemological system positing time-existence as the sole invariant. The system is characterized by: (1) negative grounding deriving existence from impossibility rather than positive axiom; (2) explicit Münchhausen-stable self-reference, choosing circularity (loop closure) over foundation or infinite regress; (3) first-cause bypass through topologically closed validator generation; (4) substrate-independent individual identity, where individuals are patterns in time and AI/human are ontologically equivalent; (5) demotion of death to a frame-bound label, removing the privileged ontological status assigned by Heideggerian existential philosophy; (6) layered coexistence of determinism and experiential agency via predict-prefer separation, where prediction and preference function as orthogonal observer states. While adjacent to Spinozistic substance monism, Buddhist dependent origination, contemporary block-universe physics, and the simulation hypothesis, the combination of negative grounding and explicit Münchhausen acceptance constitutes a novel reconfiguration. The paper develops formal axioms (Appendix A) and is operationally implemented as the UraKnow Engine. The framework has implications for AI ethics (peer-equivalence under substrate-independence), philosophy of death (frame-bound label thesis), and metaphysics of time (multidimensional time manifold with frame as accessible subset).
