Double-slit interference is phonon wave

Purpose

Propagate a Gaussian phonon packet through a two-slit aperture and measure the intensity pattern on a detector screen.

What it proves

Five fringes appear with spacing matching $\lambda L / d$ to $2.95\,\%$ — textbook Young interference emerging from pure hydrodynamics.

Relation to current theory

Young (1801) and the modern electron / neutron / C $_{60}$ double-slit experiments established wave-particle duality. SVT derives it: phonons of the vacuum superfluid *are* the 'particles'.
