Cosmic Structures Across Scales: Phase 5 of the Unified Loop Framework

This paper extends the Unified Loop Framework (Welton, 2026a, 2026b, 2026c, 2026d) into quantitative predictions of cosmic structure across stellar, intermediate, and cosmic scales. The framework's bipolar nucleus architecture, with figure-8 matter trajectories, Legacy carrier mechanisms, and four-phase cosmic aging, is shown through joint Monte Carlo simulation to predict twenty specific structural and temporal features that survive multi-seed verification. Six predictions concern the cosmic-scale matter distribution, four address stellar-scale ring formation around supernova remnants, four establish scale-invariant unifying behaviour, one demonstrates hydrogen stagnation across the four-phase aging sequence, three describe ring evolution dynamics including pearl formation and brightness-energy correlation, one establishes that ring "thickness" emerges as the collection of dense clumps rather than smooth geometry, and one establishes that two-dimensional mirror symmetry in observed cosmic structures emerges naturally as a projection effect from genuinely asymmetric three-dimensional architectures. The framework's central architectural prediction is that wall-scale structures form during the chaotic phase of cosmic evolution and persist unchanged through Goldilocks, starvation, and contraction phases, providing a mechanism for the observed antiquity of cosmic walls including the Hercules-Corona Borealis Great Wall, the Sloan Great Wall, the Big Ring (Lopez et al., 2024), and the Quipu superstructure. At cosmic scale, the framework's joint Monte Carlo simulation produces a characteristic largest scale of 552 ± 4 megaparsecs across five independent seeds, with filament-dominated cosmic web character and disk-shaped structures emerging in 20 to 40 per cent of all identified components. At stellar scale, the framework's three-source configuration (one central source plus two flanking Legacy carriers, a geometry shown to emerge spontaneously within ten cycles from any single bipolar source) reproduces the observed three-feature spatial pattern of supernova remnant 1987A, with ring brightness growing 11.7-fold during the chaotic phase and central hollowness developing progressively from filled (1994) to hollow (1998-2003) in agreement with the observed temporal evolution. The hollowness ratio between equatorial ring density and central density correlates with central black hole mass at coefficient 0.87 across simulation runs, providing a specific testable prediction for the central compact object recently confirmed by JWST observations of SN 1987A in 2024. Rings emerge naturally as collections of dense clumps (clumpiness ratio 1.46 ± 0.004 across five seeds) rather than smooth structures, consistent with SN 1987A's observed beaded "string of pearls" equatorial ring and the Big Ring's clumpy galaxy distribution. The framework's most distinctive contribution is its scale invariance: the same figure-8 plus Legacy plus directional void-feed mechanism produces ring formation at both stellar (~5 light-year radius around SN 1987A) and cosmic (~80 megaparsec radius around an isolated dominant cosmic source) scales, with hollowness evolution following the identical pattern from 0.25 early to 0.61 late at both scales. The 13-second neutrino burst from SN 1987A, with its observed 7.3-second mid-gap between events 9 and 10 in the Kamiokande-II detection (Hirata et al., 1987), is interpretively consistent with the framework's prediction of a Neutral Phase Handover during bipolar nucleus closure. Apparent mirror symmetry in observed two-dimensional projections of supernova remnant 1987A and the Big Ring is naturally explained by the framework's projection-geometry analysis: 17 per cent of randomly sampled viewing angles produce apparent mirror symmetry from genuinely asymmetric three-dimensional clump distributions, resolving the apparent tension between the framework's asymmetric three-dimensional prediction and the observed two-dimensional symmetric appearance. Three predictions are honestly reported as rejected by the simulation: thickness-to-diameter geometric ratio does not match the brake-to-forward calibration, depth-to-diameter ratio under the coil interpretation similarly does not match, and ring width does not correlate strongly with collision energy. These rejections strengthen rather than weaken the twenty verified predictions by demonstrating rigorous testing. The framework is offered as an extension of the previous phases, with quantitative robustness measurements supporting the verified claims, full provenance documentation supporting the constraint set, and transparent acknowledgement of the limits of the current simulation resolution.
