Quantum Space Time Fabric Part I Version 2

We propose a geometric framework (Quantum Spacetime Fabric, QSTF) in which quantum phenomena arise from particle geodesics on a hypercomplex spacetime metric Qμν constructed from the 16-component Clifford algebra Cl(1,3). Higher-grade metric components encode quantum behavior — interference, tunneling, measurement, and entanglement — within covariant spacetime geometry. We derive an effective field equation (□ − mH²(T))Hμν = −κH Sμν for the higher-grade sector, with a temperature-dependent mass encoding the superconducting Meissner transition as a propagator modification. This yields a sharp experimental prediction: for niobium double slits cooled below Tc = 9.3 K in zero external field, QSTF predicts a fringe shift of 0.10–0.15 rad from boundary-localized metric perturbations over the London penetration depth. Standard quantum mechanics predicts zero shift. The falsification threshold is 0.01 rad, within current electron holography resolution. To the authors' knowledge, no such experiment has been performed.
