Why Spacetime Stiffness May Permit Persistent Transport Corridors A Conceptual Bridge Between General Relativity and the SP3 Framework

Einstein’s General Relativity describes gravity as curvature of spacetime produced by
mass-energy. The coupling between energy density and curvature is extremely weak,
implying that spacetime behaves as an extraordinarily stiff medium. While this stiffness
limits large curvature distortions, it may also allow small structural perturbations to persist
once formed. The Space-Phase (SP3) framework proposes that repeated flux of matter and
energy may condition the spacetime substrate, producing persistent transport pathways
referred to as coherence corridors. This paper examines how the extreme stiffness implied
by Einstein’s field equation may permit the long-term persistence of such subtle structural
organization.
