Collective Photon Traffic and Space-Phase Conditioning: A Dimensionless Conditioning Ratio in the SP3 Framework

In the SP3 framework, matter and radiation play distinct roles in shaping the state of spacephase. While massive bodies establish localized saturation profiles, propagating lightcontributes a distributed conditioning that depends on aggregate photon traffic rather thanindividual interactions. This paper examines how near-Sun probes—impulsive lightdeflection and recurrent planetary motion—highlight this distinction, and extends thediscussion to cosmic regimes where photon flux may be low, such as the early or highlyexpanded universe. A dimensionless conditioning ratio is proposed, combining photonflux with the saturation relaxation timescale 𝜏, to characterize whether light-drivenconditioning is sufficient to maintain structured space-phase between matter anchors. Theratio does not predict outcomes but provides a framework for comparing regimes andbounding SP3 behavior across epochs.
