Abstract
The Hubble tension is inherently multidimensional and bears important implications for parameters beyond ${H}_{0}$. We discuss the key role of the matter density parameter ${\mathrm{\ensuremath{\Omega}}}_{m}$ and the physical cold dark matter density ${\ensuremath{\omega}}_{c}$. We argue that once ${\mathrm{\ensuremath{\Omega}}}_{m}$ and the physical baryon density ${\ensuremath{\omega}}_{b}$ are calibrated, through baryon acoustic oscillations (BAO) and/or type Ia supernovae (SNeIa) for ${\mathrm{\ensuremath{\Omega}}}_{m}$, and via big bang nucleosynthesis for ${\ensuremath{\omega}}_{b}$, any model raising ${H}_{0}$ requires raising ${\ensuremath{\omega}}_{c}$ and, under minimal assumptions, also the…
