Cosmological constraints on the big bang quantum cosmology model
arXiv:2603.25999 · doi:10.1103/k1nl-rxsy
Abstract
The big bang quantum cosmology model introduces the trace of the Schouten tensor as a form of dynamic dark energy. Together with cold dark matter, these components form the so-called CDM cosmology model, proposed by M.H.P.M. van Putten (J. High Energy Astrophys., 45, 2025, 194), which offers a potential resolution to the Hubble tension. We derive the constraints on the CDM cosmology model, utilizing early- and late-time cosmological data including cosmic microwave background (CMB), baryon acoustic oscillations (BAO) released by the Dark Energy Spectroscopic Instrument (DESI), cosmic chronometers (CC), and type Ia supernovae (SNIa). For a flat universe, the CDM model yields \( H_0 = 66.95 \pm 0.51 \, \rm{km~s^{-1}~Mpc^{-1}} \) and \( Ω_m = 0.3419 \pm 0.0065 \), results that are consistent with early-universe observations but exhibit a higher \( Ω_m \) compared to the CDM model. In the case of a non-flat universe, CDM favors a slightly curved geometry with \( Ω_k = 0.0154 \pm 0.0027 \), leading to \( H_0 = 69.13 \pm 0.56 \, \rm {km~s^{-1}~Mpc^{-1}} \) and \( Ω_m = 0.3477 \pm 0.0074 \). The increase in \( H_0 \) in the non-flat scenario suggests a geometric degeneracy between spatial curvature and \( H_0 \). We also investigate the internal inconsistencies present in DESI data and evaluate their impacts on cosmological parameter constraints. Our analysis shows that while the CDM model, which is constructed from first principles without free parameters beyond those of CDM, agrees excellently with late-time cosmology, it struggles to simultaneously match early-universe observations in a fully self-consistent manner.
