Questioning the $H_0$ tension via the look-back time

Understand

The Hubble tension is investigated taking into account the cosmological look-back time.

• Specifically, considering a single equation, widely used in standard cosmology, it is possible to recover both values of the Hubble constant $H_0$ reported by the SH0ES and Planck collaborations: the former is obtained through cosmological ladder methods (e.g.
• Cepheids, Supernovae Type IA) and the latter through measurements of the Cosmic Microwave Background.
• Also, other values obtained in the literature are achieved with the same approach.
