Light in SP3: Space-Phase Reconfiguration Replaces Wave–Particle Duality

Light has historically resisted a single physical interpretation, exhibiting wave-likeinterference, particle-like energy exchange, and invariant high-speed propagation throughspace. These behaviors led to the concept of wave–particle duality, an interpretivecompromise rather than a unified physical explanation. In the SP3 framework, space itselfis not empty or passive but possesses phase, memory, and the capacity for conditioning.This paper reframes light as a localized, self-maintaining reconfiguration of space-phaserather than a particle moving through emptiness or a field oscillating in a void. Interference,quantization, constant propagation speed, and gravitational bending arise naturally fromthe properties of space-phase itself. Wave–particle duality is therefore not resolved bychoosing one description over another but is eliminated by replacing an incompleteconception of space with a physically active medium.
