The Graham-Lahoz Experiment Revisited: Exact Prediction from Structured Vacuum Theory

This paper demonstrates that the Structured Vacuum Theory (TVS) quantitatively predicts the torque measured in the 1980 Graham-Lahoz experiment without arbitrary parameters. The experiment, in which a cylindrical capacitor discharged in a static magnetic field produced a torque 150 times smaller than the classical prediction, has long required the ad-hoc concept of "hidden momentum." TVS explains the reduction through a geometric factor 1/23², representing the impedance between the vacuum's 23 helical channels and baryonic matter. The calculated torque of 2.11×10⁻¹⁰ N·m matches the measured 2.1×10⁻¹⁰ N·m with 0.5% accuracy, providing direct experimental evidence for the vacuum's discrete torsional structure and eliminating the need for fine-tuned hidden momentum.
