Superfluid String Dynamics (SSD): A Deterministic Hydrodynamic Replacement for Quantum Mechanics

Standard Quantum Mechanics (QM) relies on the probabilistic interpretationof the wavefunction, treating measurement as a non-deterministic collapse. Thispaper proposes a deterministic replacement based on my previous work creatinga Grand unified field theory: Superfluid String Dynamics (SSD). We postulatethat the vacuum is a 6-Dimensional Superfluid composed of string intersections.We rigorously derive the Schr¨odinger Equation from the Navier-Stokes equationsof this fluid, identifying the wavefunction ψ as a physical density field. We demonstrate that ”Quantum Weirdness”—including Superposition, Tunneling, and Uncertainty—emerges naturally from classical fluid dynamics at the Planck scale. Weprovide step-by-step derivations and comparative calculations showing that SSD reproduces the statistical predictions of QM while restoring local realism and causality.
