Foundations of an Informational Phenomenology of the Universe: Constructive Derivation from Non-Non-Event

We propose an informational phenomenology of the universe as a constructive derivation of physical reality from a single principle: non-non-event (¬¬E). The derivation proceeds in three stages. (1) Pre-geometric stage: ¬¬E generates boundaries as pure information via the von Neumann construction; no motion, no gradient, only information. (2) Geometric emergence: when the state space acquires statistical manifold structure, the Fisher information metric uniquely determines geometry (Chentsov). (3) Post-geometric stage: information becomes dynamically actualized; boundaries act as information carriers that initiate physical processes. We argue this structure is universal — from black hole horizons to DNA, from quantum measurement to social institutions. The three structural theorems correspond to the Second Law, Prigogine's dissipative structures, and England's dissipative adaptation. Photon spin-1 is identified as the minimal unit of information transmission; electron spin-1/2 as the minimal structure realizing symmetric coexistence of the two directions in matter. The fine-structure constant α may be interpretable as the probability of information-to-physics coupling in three-dimensional geometry. The framework positions recent quantum-gravity results on entanglement-based spacetime emergence (Van Raamsdonk, Ryu-Takayanagi) and Bianconi (2025) gravity-from-entropy as rigorously established instances of a more general principle.
