On the Maximum Admissible Concentration of Reality and the Structural Origin of Gravitational Singularities

Description This white paper addresses one of the most persistent open problems in fundamental physics: the unresolved status of gravity with respect to quantum theory. Rather than proposing a new gravitational model or an additional quantization scheme, it argues that the difficulty arises from a misplacement of the core question itself. Current approaches implicitly assume that gravity must be quantized in the same manner as other interactions. However, despite decades of mathematical sophistication, no empirical evidence of gravitational quanta has been observed, and singularities remain unavoidable across frameworks. This paper proposes that the impasse is not primarily technical, but structural. The central contribution of this work is the introduction of coherence phenomenale as a minimal, pre-theoretical admissibility constraint. Coherence phenomenale is defined as the condition that allows physical reality to persist without internal contradiction, to maintain temporal continuity, and to avoid requiring infinite compensations or non-physical cancellations. This notion does not introduce new entities, forces, or fields. It operates as a structural filter applicable to any physical description, classical or quantum. From this perspective, the traditional question “Is gravity fundamentally quantum?” is reformulated into a more foundational one: What is the maximum concentration of matter–energy–information that a physical framework can sustain without violating coherence and temporal continuity? Within this framework, gravitational singularities are reinterpreted not as physical objects, nor as mere mathematical pathologies, but as coherence thresholds. They mark the point at which a given descriptive framework exceeds its capacity to remain admissible. A singularity therefore signals not “infinite matter,” but the breakdown of coherence within the model itself. This shift allows gravity to be interpreted as a regulator of coherence, constraining how reality can concentrate without contradiction. Whether gravity is ultimately quantized becomes a secondary question; the primary requirement is that any proposed theory must preserve coherence under extreme conditions. Quantization is acceptable only insofar as it respects this constraint. The paper does not claim to solve quantum gravity, to replace General Relativity, or to modify quantum mechanics. Its contribution is structural rather than predictive. It provides a criterion that can be used to evaluate existing and future approaches—classical, quantum, effective, or emergent—by asking a single question: does the framework remain coherent under maximal concentration, or does it collapse into contradiction? By restoring admissibility as a first-order concern, this work clarifies why singularities persist, why certain theoretical paths repeatedly fail, and why progress in quantum gravity may require re-framing the problem rather than extending existing formalisms. The paper is intended as a conceptual foundation, opening a clearer and more constrained space for future theoretical developments.
