Quantum Core Modeling in Black Holes: From Quantum Hydrodynamics to Observable Signatures

Building upon the quantum-fluid-corrected Einstein equations, this study de-rives a fully consistent model for the interior of black holes as quantum cores stabi-lized by the Bohmian quantum potential and Fisher information energy. We cal-culate the radius of the quantum core, show how the collapse halts before reachinga singularity, and provide predictions for observable deviations in black hole shad-ows and gravitational wave signals. This framework offers a testable alternativeto classical singularities and links quantum hydrodynamics with astrophysical datafrom the Event Horizon Telescope. [cite: 1038, 1039, 1040, 1041]
