The gravitational constant G occupies a central yet conceptually unresolved position in modern physics. Introduced as the coupling parameter between curvature and stress–energy in Einstein’s field equations, G determines the strength of gravitational interaction but lacks a structural derivation. Its measured value remains experimentally delicate, and its physical interpretation is traditionally treated as primitive. In this work, we propose a reinterpretation of G within the framework of Viscous Time Theory (VTT), treating it not as a fundamental constant, but as an emergent informational coupling operator. Specifically, we demonstrate that G can be understood as the inverse susceptibility of emergent geometry to identity-preserving informational tension (Δ
