(Part 36) Light, Photon, and Null Structure — Paper 407–415.-.-.pdf

This series reformulates light and photons without treating them as physical entities or carriers of energy. Light is described as a manifestation of null structure — the limiting geometry of causal relations — rather than as a propagating object or field excitation. Photons are identified as measurement-induced events, not pre-existing particles. Energy transfer is reinterpreted as constraint reconfiguration between emission and absorption, eliminating the need for energy transport through space. Null geometry is shown to possess causal structure without spatial extension or motion, functioning as the backbone upon which spacetime descriptions emerge. Measurement is placed prior to photon event formation, resolving longstanding paradoxes concerning localization, time experience, and the rest frame of light. The work removes object-based assumptions from electromagnetism and quantum optics, establishing a constraint-first, event-based framework that remains internally consistent without invoking hidden variables or additional postulates. The series concludes by identifying null structure as the boundary beyond which physical description ceases to be meaningful.
