No Big Bang: Vacuum-Polarized Growth in High-z Galaxies

The distant galaxies GN-z11 (z ≈ 10.957) and CAPERS-LRD-z9 (z ≈ 9), recently observed with the James Webb Space Telescope (JWST), challenge conventional cosmology with their compact sizes, remarkably compact morphologies, intense starburst activities, and over massive central supermassive black holes (SMBHs) relative to stellar masses. GN-z11's SMBH is approximately 1.6 × 106 solar m...
