This paper examines the relationship between the large‑scale filamentary structure of theuniverse (the cosmic web) and percolation network theory, and interprets these structureswithin the SP3 (space‑phase) framework. Cosmological observations and simulations revealthat matter in the universe is organized into a hierarchical network composed of voids,sheets, filaments, and nodes. Percolation theory provides a mathematical description ofhow connected pathways emerge within complex systems. In the SP3 interpretation, thesepathways correspond to coherence corridors formed through repeated matter‑energytransport within the spacetime substrate. Filament intersections represent nodes wheretransport converges and energy density increases. This paper outlines the conceptualmapping between percolation networks, cosmic web structure, and SP3 corridor dynamics,and discusses how observational features such as galaxy spin alignment, filament vorticity,and cluster energy concentration may serve as markers of corridor‑based transportdynamics across cosmological scales.
