The Photon as a Spatial TSO: Measurement, Polarisation, and Emergent Frequency

This article presents a new physical picture of the photon based on the Time–Space Oscillation (TSO) framework. In this model, free light contains no temporal oscillation at all: its structure is entirely spatial (t=0, x -> infty). Wave-like behaviour, frequency, and even polarisation do not exist intrinsically, but appear only when a photon interacts with matter. We show that measurement itself generates the observed electromagnetic oscillation by projecting the spatial TSO onto the detector’s mixed time–space basis. This mechanism produces: an emergent electromagnetic frequency determined by the detector’s local TSO rate and interaction energy, particle-like absorption whenever the detector locally captures the TSO energy packet, and exactly two observable polarisations, arising from the two allowed electron–positron pair combinations within the photonic TSO microstructure. The resulting framework reproduces all standard optical outcomes yet replaces the conventional “photon as a wave–particle” duality with a single coherent structure. The paper provides analytic expressions for measurement probabilities, polarisation selection rules, and frequency emergence, together with clear experimental signatures suitable for cavity QED and precision optics tests. This work extends earlier TSO studies on zero-energy states and vacuum stability and offers a unified interpretation of light based purely on interaction-driven dynamics rather than intrinsic wave–particle categories.For readers new to the Time–Space Oscillation framework, a structured overview of the four foundational TSO conceptual papers is available in “Time Space Oscillations. Introduction papers” (Zenodo DOI: 10.5281/zenodo.1767154). This companion document summarises the core principles of TSO —TSO concept, Time dilation and Gravity equivalence, TSO & EM, TSO & QM—and provides direct links to the full manuscripts. It serves as the recommended starting point for understanding how the present photon model fits into the broader TSO structure.
