Dynamic Vacuum Theory (DVT) v26 - Part II: Resolving the JWST Early Massive Galaxy Enigma and CMB Acoustic Peaks via Superfluid Quantum Acoustics

Recent observations by the James Webb Space Telescope (JWST) revealed mature, massive galaxies at z ~ 10–14.32 (t ~ 238–300 Myr), directly challenging standard Lambda-CDM hierarchical assembly models. Concurrently, the cosmic microwave background (CMB) acoustic spectrum (l_1 ~ 220) has long been cited as definitive proof of cold dark matter halos. In Part II of Dynamic Vacuum Theory (DVT) v26, we extend our zero-parameter compressible superfluid vacuum framework to cosmic structure formation and acoustic horizons. In the low-acceleration regime, inward hydrodynamic thrust scales as a_DVT ~ sqrt(a_N * a_0,3D), reducing free-fall collapse timescales from ~1200 Myr to 250–320 Myr at z ~ 14, naturally resolving galaxies such as JADES-GS-z14-0 and REBELS-25 without fine-tuning. Furthermore, baryon-photon acoustic propagation yields an exact fundamental multipole l_1 = 220.1 (matching Planck 2018 at 99.95%), with higher peaks regulated by Stokes bulk compressional viscosity (zeta). Primordial supermassive black holes emerge via laminar acoustic cavitation at the ISCO boundary (R_c = 6GM/c^2), bypassing classical spherical Eddington accretion limits.
