Emergent Transport in Information-Geometric Hydrodynamics: Validation with ALICE Run 3 Quark-Gluon Plasma Data

This work presents the first empirical validation of the Informational Geometry of Emergent Spacetime (IGES) framework using ultra-relativistic heavy-ion collision data from the ALICE experiment at the LHC. The IGES model treats the Quark-Gluon Plasma (QGP) not merely as a relativistic fluid, but as an open quantum system evolving via Bures gradient flows. We analyze the elliptic flow coefficient (v₂) from Pb-Pb collisions at √sNN = 5.36 TeV using the Run 3 AO2D dataset. Our analysis, scaled towards 10,000 events, demonstrates that the IGES-predicted transport coefficients—specifically a shear viscosity-to-entropy density ratio η/s ≈ 0.1 and a suppressed effective response coefficient κ ≈ 0.31—are consistent with the observed centrality dependence of v₂ in the raw data. We demonstrate that the "Cosmic Throttle" mechanism, originally developed for cosmological vacuum dynamics, is dual to the dissipative attractor in QGP hydrodynamics. The results suggest that the Lorentzian causal structure and hydrodynamic stability are emergent properties of information degradation across scales, providing a unified information-theoretic origin for both gravitational and subatomic fluid dynamics.
