Abstract
GETT Resolves Young’s Double-Slit Experiment — J. E. Holland (2025)** This paper presents a complete physical resolution of Young’s double-slit experiment using the General Expanse Tension Theory (GETT) framework. GETT models all matter as localised excitations of a real, gauge-invariant scalar field Φ, and all wave-like behaviour as small propagating perturbations of this field, known as Expanse Tension Ripples (ETRs). These ripples are launched at the instant of particle emission and propagate at near-light speed. As two ETRs pass through the slits and interfere, they imprint a dynamic tension landscape into the Φ-field. The particle core does not superpose or interfere with itself; instead, it is continuously guided by the local tension gradient generated by the interference of the real δΦ waves. Note: The ETT / GETT framework and theory was developed to address macro-scale cosmic anomalies, galaxy rotations and late time accelerations, this paper simply applies the framework previously developed to this new application. The result is a deterministic, mechanistic explanation of the double-slit experiment that reproduces all key observations traditionally attributed to quantum wave–particle duality. The guidance mechanism emerges from the Φ-field’s density-dependent tension and operates smoothly across time: as the ETR interference pattern forms and sharpens, the particle experiences corresponding changes in the local tension slope, steering it toward regions of lowest tension. Across many single-particle events, this produces the observed statistical fringe pattern without invoking wavefunction collapse, superposition of particle trajectories, or any probabilistic interpretation of the particle itself. The paper includes: A full historical analysis from Hooke, Huygens, and Young to modern single-particle interferometry. A detailed explanation of Φ-field dynamics and the origin, propagation, and interference of ETRs. A time-resolved account of how the particle is guided by evolving tension gradients. A comprehensive 12-phase sequence describing the complete physical process from emission to detection. A mathematical core (Appendix N) giving the field Lagrangian, δΦ wave equation, tension structure, and force law. A simulation appendix (Appendix Q) demonstrating numerically that Fresnel-propagated ETRs, combined with tension-gradient guidance, reproduce the expected interference pattern without wavefunctions. A new visual appendix (Appendix R) illustrating the dynamic evolution of the interference landscape and real-time particle guidance. A predictions section (5.8) giving concrete, testable numerical signatures of GETT in modern interferometry, including expected fringe shifts, timing offsets, and modulation depths. This work shows that the double-slit experiment can be fully explained using only a single real field, its perturbations, and their tension gradients—without the conceptual difficulties of standard quantum mechanics. It provides a unified, physically transparent account that is consistent with all single-particle observations from Taylor (1909) to Tonomura (1989) and with modern weak-measurement and biprism experiments. By resolving the double-slit experiment using deterministic field physics, this paper strengthens the broader GETT programme, in which the Φ-field and its density dependency unify gravity, inertia, cosmology, and particle behaviour within a single theoretical structure. This study demonstrates that GETT naturally reproduces quantum interference and offers a clear, testable alternative to traditional quantum interpretations.
