Near-Death Experience as a Proxy for Black Hole Event Horizon Phenomenology: A Testable Prediction from the Intersection of General Relativity and Consciousness Research

Abstract

Time presents physics with a fundamental paradox. The laws governing matter are time-symmetric, yet conscious experience is irreversibly directional. At the deepest level of physical description, the Wheeler-DeWitt equation of canonical quantum gravity lacks time entirely, raising the question of how temporal experience emerges from a timeless physical substrate. Both problems converge on a common empirical gap: no data exist from the physical regime in which time, as ordinarily experienced, breaks down. This paper proposes that near-death experiences (NDEs) constitute a previously unrecognized empirical window into precisely this regime. We identify a structural correspondence between the phenomenological sequence reported by NDE experiencers and the sequence of physical changes predicted by general relativity for an observer approaching a black hole event horizon. In both cases, the trajectory proceeds from progressive temporal distortion through the dissolution of spatial boundaries to the complete absence of sequential time, a three-stage progression consistent with the mathematical relationship described by the Schwarzschild metric. This application of black hole event horizon physics as a predictive framework for NDE phenomenology is, to our knowledge, without precedent in the literature. From this correspondence, we derive two specific and falsifiable predictions. First: the degree of time distortion reported in NDEs, as quantified by the validated 16-item Greyson NDE Scale, should correlate with NDE depth following the same mathematical form as gravitational time dilation near the Schwarzschild radius. Second, the neurophysiological signature of the NDE state should display a characteristic two-phase pattern: an initial surge of high-frequency gamma coherence followed by a rapid collapse to minimal activity, consistent with the catastrophic failure of the decoherence-maintaining machinery of normal consciousness. Both predictions are testable using existing data without new experimental procedures. If confirmed, this framework would constitute the first empirical test of a prediction derived from an event-horizon-inspired model applied to consciousness data, and would provide a novel approach to the problem of time in quantum gravity.
