The afterimage can 'ripple outward' from any major construction, theoretically without end, and with varying intensities.
后像可从任何主要建构向外“涟漪式扩散”，理论上没有尽头，且强度各不相同。

This program treats the Seth Material as a source of hypotheses, not as doctrine to be validated. Lead dossiers are AI-compiled from the corpus with a book-and-session citation after every statement; literature reviews are AI web-search summaries whose references were all DOI-verified against Crossref; the agenda draft is an AI synthesis. None of it is Seth's original text, and none of it represents scientific consensus. English fields are machine-translated; the Chinese text is authoritative.
Seth sources (book §session)
Adjudicating experiment
First, 'ripple' must be defined as an externally detectable signal, specifying the signal carrier, frequency band, propagation speed, and amplitude as a function of distance. In a shielded environment, randomly start or not start a standardized stimulus source, deploy synchronized detectors at 0.1, 1, and 10 meters, complete 10^4–10^5 blinded events over 6–12 months; compare electromagnetic, acoustic, and thermal conduction models with the pre-registered extra propagation term. If the claim refers only to subjective afterimages, separate spatial diffusion experiments in retinal coordinates should be conducted, and the two types of evidence must not be conflated.

A Preregistered Search for Residual Propagating Signals Following Controlled Stimulus Events
What it would overturn
Only if signals beyond predictions of existing carriers are detected would it revise the hypothesis that propagation from a given physical source can be explained by known interactions and their field equations.
Specificity of Seth's formulation
'Varying intensity' and 'can spread indefinitely' also apply to ordinary waves; the original text provides no amplitude, speed, or distance scales for an extra signal, lacking discriminative power.
Note
Experiments with finite distance and sensitivity cannot prove 'theoretically without end'; far-field propagation of ordinary radiation, visual filling-in, and neural activity spread are not direct evidence for this ontological claim.
