Galaxy dynamics tracing quantum cosmology beyond ACDM below the de Sitter scale of acceleration

It is proposed that the baryonic Tully-Fisher relation (bTFR) and JWST 'Impossible galaxies' at cosmic dawn are unified in weak gravity by the trace J of the Schouten tensor below the Sitter scale of acceleration a(dS )= cH, where c is the velocity of light and H is the Hubble parameter. Across a(dS), J parametrizes short-period galaxy rotation curves and fast gravitational collapse beyond the predictions of Lambda CDM. The sensitivity of weak gravitation to J=16R is derived in infrared gravitation from a consistent limit of quantum gravity, reducing to general relativity in the limit of a small Planck constant, where R is Ricci scalar tensor. For the first time, it identifies the exact relation a(0 )= c(2 )root J/2 pi of the Milgrom parameter across all redshifts, accounting for the bTFR and early galaxy formation accelerated by a factor similar to J(1/8). It predicts a ' 0(0)<0 at the present epoch.
