Structural Plenitude Theory describes the vacuum not as emptiness, but as a continuous, viscoelastic substrate — the Pleroma — whose structural tensions govern light propagation, gravitational coupling and cosmological redshift.
In this framework, physical phenomena are not isolated interactions, but emergent responses of a dense underlying medium. Objects such as 3I/ATLAS exhibit measurable structural drag, asymmetric radiative signatures and impedance transitions consistent with substrate interaction models.
The upcoming passage near Jupiter provides a critical observational window. Within SPT, massive bodies are not merely gravitational wells, but regions of altered substrate impedance. The Jovian interaction phase offers a natural test for structural coupling predictions.
The objective is not speculative replacement, but structural reinterpretation of observational anomalies within a physically continuous cosmological architecture.
