Light Without Particles: Reassessing Wave–Particle Duality Through Field Geometry

For over a century, physics has taught that light is “both wave and particle,” with the photon elevated to a fundamental constituent of nature. This article revisits how thecorpuscular picture of light became dominant—from Newton and Huygens to Einstein’s photoelectric effect and Compton’s scattering—and argues that much of the alleged evidence for photons as “particles” can be reinterpreted more economically in a purely wave-based framework. We highlight a conceptual tension of twentieth-century quantum rhetoric: electrons and photons are routinely described as if they “knew” our experimental intentions, while any serious discussion of consciousness beyond humans is dismissed as unscientific. Building on a recently proposed geometric reinterpretation of the Compton effect—where the wavelength shift arises from field–structure coupling rather than particle–particle collisions—we show how the photoelectric effect and double-slit experiments can likewise be understood without attributing ontological particle status to light. Discreteness emerges not from light being made of corpuscles, but from quantized field modes and the event-like nature of charge in matter. The electromagnetic field remains a wave throughout; only matter clicks. This work integrates new conceptual insights, including two revealing paradoxes of the standard narrative and three implicit principles that guide our geometric reinterpretation, while preserving the full depth and detail of the original analysis.
