Geometry as Cause, Waves as Language

The concept of a wave occupies a central place in modern physics, from classical me-chanical phenomena to quantum mechanics. However, contemporary usage of the term wavecovers ontologically distinct realities, ranging from propagative structures of a medium topurely mathematical descriptive tools. Within the framework of the five-dimensional solitonictheory (TS5D), physical objects are described as solitonic excitations of the geometric fielditself, rather than as fundamental linear waves. We propose here a coherent re-examinationof the notion of wave, of Young’s double-slit experiment, and of Fourier analysis, showingthat the wave constitutes an effective descriptive language, while geometry and topologyplay a fundamental causal role.
