Internal-Informational Quantum Theory (IFT-ISE) From Double-Slit Interference to Black-Hole Informational Horizons Complete Theoretical and Experimental Edition

IFT-ISE is a unified quantum-informational model that attributes wave–particle transitions to the interaction between spatial informational gradients and a discrete internal informational state space. The Local Informational Field (LIF), defined through local entropy, acts as an effective potential shaping spatial amplitudes, while the internal subsystem regulates contextual mode selection. This formulation extends the photonic Hilbert space to include informational degrees of freedom and provides a physically interpretable mechanism underlying quantum contextuality. The model reconstructs the double-slit experiment, predicts upstream coherence modulation prior to slit interaction, and formalizes an entropy-based collapse criterion. The same dynamics extend to black-hole horizons, producing an information-amplification law derived from Schwarzschild geometry. Full mathematical derivation, diagrams, and experimentally testable predictions are provided, offering a coherent informational foundation for quantum optical phenomena.
