The double-slit experiment is usually taken as evidence that a particle is also a wave. We show by simulation that a definite particle, moving through a physical medium and guided by its own wave, produces the same interference pattern, with no constant fitted to the pattern. Space is modeled as a compressible particle medium with a short-range stiffness. A particle set in motion disturbs it once. The disturbance disperses, and the particle carries with it the part of the wave whose group velocity matches its own speed, so the wavelength at the particle is fixed by its speed alone, λ ∝ 1/v, with no oscillator and no continued pushing. That wave passes through two slits and interferes as any wave does. The particle passes through one slit, keeps its speed, and takes its direction from the flow of the wave around it. It lands where the wave is bright. Hundreds of particles, sent one at a time, reproduce the wave's own pattern: at three speeds and two slit spacings, up to nine bright lanes with empty dark bands between them, lane spacing that scales with the wavelength of the wave it carries, the same pattern for a stream of particles as for one, and no lanes when one slit is closed. The rule that steers the particle has no strength, no frequency, and no free constant, and it is the same rule at every scale because each particle's wave is sized to itself. The result depends on one condition: that the particle's launch point lie well beyond the near-field distance of the slit pair, which laboratory sources satisfy. We record the rules that were tried and failed and the numerical pitfalls, and we state what remains open: the silent coast is a postulate, the mass dependence of the wavelength is untested, and the work is two-dimensional.

Abstract Since it was born before its physical achievements, light waves, which have almost no physical properties, are an abstract mathematical concept rather than an objective description. Confused by a set of dark and light streaks and a sketchy schematic that had little to do with the actual result, the double-slit test was misjudged as being caused by interfering light waves, so this plausible principle implied disastrous flaws. For example, (1) Just after passing through the double-slit device, the pattern is generated by light early or before interference. By changing the distance between the device and the screen, the pattern is only scaled synchronously without being reconstructed by interference, and imagined light-wave interference does not occur. (2) Interfering light waves can be subdivided into multiple parts and proliferate greatly. (3) A headless wave of light left outside the screen after the head disappears can still induce much interference. (4) There is no interference effect caused by reflected light waves. (5) The effect of polarization direction on interference is neglected, and the interference condition is incomplete. (6) In the mathematical model, not only are the spots with the highest brightness in the position where dark stripes should appear most, but the principle of generating multiple regular dark stripes cannot be found. (7) Since the quantum property must be carried out in the process of interference, if all conditions are not met at the same time, interference will not be triggered, and therefore, the principle of interference will be rejected. (8) Since light comes only from the radiation of the electron transition, it is impossible to generate a light source in a slit that may be a vacuum. (9) In the causality test, to verify the effect of collapse, the photon that has collapsed into a particle should be tested again with a double slit test. (10) Whether the phenomenon of "observed tampering results" obtained by observation has been tampered with. (11) When the phase is shifted π or the signal is reversed, waves become negative waves capable of annihilating themselves, which is typical of antimatter. In this case, matter and antimatter are conjoined. (12) If the general law of waves is followed, not only the targeted light wave passes through the slit. (13) The original version of the double-slit test cannot be reproduced, and the test results are different from those presented by contemporary technology. (14) Waves must obey Fourier's principle, but light waves, quantum waves and matter waves do not. (15) The modulation effect that waves must produce is not present in optical fiber communication. (16) If the light from different slits must interfere with each other, a mask full of slits will cause the lithographer to fail. (17) Since the size is much smaller than the wavelength, the photon is only a sampling of the light wave, but the corresponding physical properties are not presented. (18) The fact that the two stars orbiting each other do not change color only proves that the phenomenon of redshift is impossible but does not support the inference that the speed of light is constant. (19) The Michelson-Morley test process is not open and transparent enough, and pinhole diffraction and mechanical processing using broken lines instead of curves cannot be ruled out. (20) Kepler's law can block Hubble's law and its derivatives, dark matter and dark energy. In conclusion, Newton's particle model was wrong, but neither was the light wave theory.

The double-slit experiment has stood for a century as the paradigmatic demonstration of quantum superposition: the standard interpretation holds that a particle passes through both slits simultaneously, existing in a superposition of two spatially separated states. This paper proposes a physically distinct alternative: the particle's matter wave — a real physical wave propagating through space in accordance with de Broglie's relation λ = h/p — passes through both slits, while the particle itself (matter) remains in an undetermined state until a constructive interference maximum is formed at the detection screen. The particle does not simultaneously occupy two locations; the wave does. This distinction eliminates the need for superposition as an ontological commitment while fully reproducing the observed interference pattern. We further show that the disappearance of the interference pattern upon which-path measurement is explained without invoking wavefunction collapse: the measurement interaction redirects the matter wave to a single-slit geometry, eliminating the two-wave interference condition. Three experimentally testable predictions distinguish this framework from the standard interpretation: (1) weak-measurement trajectory reconstruction should reveal single particle paths inconsistent with simultaneous two-slit passage; (2) diffraction fringe spacing should depend on the mass density of the slit material, because denser slit edges generate a steeper refractive-index gradient for the matter wave; (3) the fringe pattern should exhibit a density-dependent phase shift measurable with current matter-wave interferometry technology. This reinterpretation requires no new mathematical formalism — the Schrödinger equation and Born's rule are retained — but replaces the ontological claim of simultaneous multi-location existence with the physically consistent picture of matter-wave propagation through an undetermined-state particle.
Based on the basic version of the Double-slit experiment, a coherent light source, such as a laser beam, illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen — a result that would not be expected if light consisted of classical particles. Our new variant is as below: We shut one of the two parallel slits once the light passed the slits. Or we keep the two slits shutting and opening randomly in high speed. We believe this variant experiment could lead to a farther fundamental understanding of the Quantum Mechanics.
