- Abstract
A critical discussion on the H 0 Hubble constant tension is presented by considering both early and late-type observations. From recent precise measurements, discrepancies emerge when comparing results for some cosmological quantities obtained at different redshifts. We highlight the most relevant measurements of H 0 and propose potential ideas to solve its tension. These solutions concern the exploration of new physics beyond the Λ CDM model or the evaluation of H 0 by other methods. In particular, we focus on the role of the look-back time.
