Hydrodynamic Shockwaves and Wave-Particle Duality

Legacy quantum mechanics relies on abstract probability distributions to explain Wave-Particle Duality, abandoning physical determinism in favor of Statistical Uncertainty. This manuscript resolves that anomaly by defining the Quantum Vacuum as a highly pressurized, structured fluid medium. Under the Electron Flow Model (EFM), elementary particles are not dimensionless mathematical points, but localized fluid solitons propagating through the Universal Vacuum Flux. Our analysis demonstrates that the observed interference patterns in the Double-Slit Experiment are generated by the Macroscopic Physical Bow Waves of the soliton. These Bow Waves sever and recombine after passing through the slits to create a standing wave interference pattern of Pressurized Ridges and Thermodynamic Troughs. The localized particle itself travels strictly through a single path, naturally surfing these pressure ridges to land on the detector screen. This framework moves beyond interpretation by establishing clear, Falsifiable Predictions that structurally distinguish the EFM from standard Quantum Mechanics: Viscous Damping: Predicts an additional mechanical channel of decoherence driven by dynamic fluctuations in the ambient pressure of the vacuum flux, scalable by the fluid bulk viscosity. Absolute Vacuum Pressure Shift: Suggests a measurable fringe compression in orbital cold-atom interferometry relative to sea level, driven by the absolute density of the vacuum flux. The v-Causal Temporal Limit of Delayed Choice: Establishes a concrete 0.51-picosecond switching threshold for tabletop delayed-choice experiments (48 m), scaling linearly to 12.6 nanoseconds at satellite-class baselines (1,200 km). The EFM predicts a physical persistence of the interference pattern—and a breakdown of quantum correlations—if measurement switching occurs faster than the finite acoustic transit time of the fluid tether. The Unified Fluid Cosmos Framework: This paper serves as Manuscript 21 Version 1 in the comprehensive series, Marabūt's Theory of Gravity. It presents the Electron Flow Model (EFM), a generative, fluid-dynamic framework designed to fundamentally replace Albert Einstein's General Relativity and standard Quantum Mechanics. The EFM shatters classical circularity with a single, undeniable foundational premise: Gravity is Pressure, not curvature, and not an intrinsic mass property.
