Timing Patterns of Electromagnetic Signals Versus Strain in LIGO Observations: A Space-Phase Interpretation

Across the catalog of detections made by interferometric observatories such as LIGO, aconsistent timing asymmetry is observed between space–time strain signals and associatedelectromagnetic (EM) emissions. Strain appears promptly, coherently, and withoutdispersion, while EM signals arrive later and exhibit strong dependence on emissionmechanism, medium opacity, and propagation path. This paper interprets that pattern usingthe Space-Phase (SP3) framework. We argue that strain reflects a state change of the spacephase carrier itself, while EM radiation must negotiate that carrier and is thereforetransport-limited. This distinction explains the observed timing hierarchy without invokingsuperluminal signaling or separate substances, and reframes LIGO as a probe of mediumstate rather than a receiver of traveling waves.
