Reconciling the Dual Nature of Photons: A Phenomenological Hypothesis of Null Metric-Memory Wakes and Intrinsic Energy-Spacetime Interaction

I propose a phenomenological geometric hypothesis in which the photon, modeled semiclassically as a localized energy packet, is associated with a weak trailing null metric-memory wake — a proposed null-directed perturbation of the metric. Within this linearized semiclassical ansatz, the transverse electromagnetic structure (understood through classical limits or transition matrix elements rather than literal nonzero field expectation values for a pure one-photon state) provides the wave-like aspect responsible for interference, diffraction, and polarization. The localized packet and its wake furnish the particle-like behavior and invariant null propagation at speed c (treated here as an input of the effective model). Consistency with the photoelectric effect is examined via the U(1) gauge structure of Quantum Electrodynamics, with energy bookkeeping and dynamical termination of the local wake addressed in the semiclassical gravity approximation. Tentative cosmological implications — frequency-independent redshift and effective large-scale backreaction — are sketched, though full agreement with observations requires separate detailed treatment. A deeperversion of the hypothesis would derive null propagation from the wake–packet interaction rather than assume it. Such an extension lies beyond the scope of the present work.
