This paper presents a structural model of the universe in which the fundamental substrate is a network of qubit-sized patches forming a nonlocal entanglement domain (E-domain). Local spacetime (S-domain) emerges as a coarse-grained description of this structure. Matter in the S-domain is anchored to extended "mats" in the E-domain, and tension within these mats encodes both gravity and dark energy. A central result is that force arises from gradients of tension at the boundaries of these mats, replacing both Newtonian action-at-a-distance and Einsteinian curvature with a unified structural mechanism.Using a qubit-based natural unit system, Newton’s gravitational constant G is derived from the structural scale of the qubit network. This derivation does not assume G=1; instead, G emerges from the qubit patch size. When expressed in SI units, the result matches the measured value G ≈ 6.674 × 10u207b¹¹ m³ kgu207b¹ su207b². Since G is derived from first principles, it is not fundamental, rather structure is fundamental.This framework naturally explains galactic rotation curves without dark matter, interprets the cosmic microwave background (CMB) as the thermal imprint of qubit-patch freeze-out , and identifies the cosmic web as the large-scale geometry of mat boundaries. The Big Bang is reinterpreted as a rapid phase transition in which the qubit patch network crystallized into its present configuration. The theory is guided by two principles: simplicity and elegance.
