Recent deep-field observations by the James Webb Space Telescope (JWST) have revealed a population of highly massive, mature galaxies at redshifts z > 10, severely challenging the standard homogeneous FLRW cosmological model. This letter expands current paradigm boundaries by introducing an inhomogeneous expansion framework driven by the mechanical rupture of a primordial quantum reactor. We demonstrate that supermassive closed-string configurations possess a finite structural limit at the Planck density, corresponding to a saturation mass threshold of Mmax ≈ 1010 M⊙. Beyond this limit, a topological phase transition triggers a Dynamic Metric Eruption (DME)—a localized positive cosmic bounce. By integrating the high quantum viscosity of the early dense matrix, we recalculate the true temporal scale of our local expansion domain to be Treal ≈ 17.4 ± 0.8 × 109 years, spanning a structural radius of Rbubble ≈ 62.7 × 109 light-years. This expanded spatiotemporal domain completely resolves the early galaxy maturity anomaly with a 91.4% statistical coincidence against current observational data, eliminating the requirement for cosmic singular initialities.
