This technical note identifies the "water hammer" sonoluminescence effect as a laboratory-scale empirical analogue for the Stage 3 "Spark" (Quantum Decoherence) mechanism within the Magnetic Quantum Cosmology (MQC) framework. While mainstream interpretations of sonoluminescence frequently focus on thermal Bremsstrahlung, this note provides a mathematical derivation using the MQC non-minimal coupling constant 0. 0674 to propose a vacuum-mediated origin for the observed light emission. By applying the quantum vacuum models of Schwinger and Eberlein, we demonstrate that the sudden arrest of liquid momentum in a vacuum-sealed environment triggers a localized dielectric perturbation. This perturbation facilitates the conversion of virtual photons into real radiation, mirroring the ongoing energy injection (the "Ongoing Big Bang") proposed in the MQC model to resolve the Hubble Tension. A falsifiable metric is established: if the radiant intensity of the water hammer spark follows 1/R⁴ geometric scaling rather than standard T⁴ thermal curves, it serves as a macroscopic confirmation of the MQC vacuum interaction logic. This document is a supplement to the primary framework: A Non-Minimal Higgs-Electromagnetic Interaction as a Unified Solution to H0, Muon g-2, and Pioneer Kinematic Anomalies (rxiVerse: 2601. 0047).
