Description
The Hubble tension has reached the 5$\sigma$ confidence threshold and is currently considered the biggest crisis for the LCDM standard model of cosmology. Yet, despite more than a decade of thorough search, a well motivated and simple solution to the Hubble tension has not emerged. In this talk I review the current observational status of the Hubble tension and what makes the problem of trying to ease it with a new cosmological model so tricky. In particular, I focus on early and late universe cosmological probes and the possible avenues of systematic failure in their determination of the Hubble constant. Then, I give a short overview of the roads that are taken towards easing the tension through new theoretical models and the general lessons that can be gleamed from those studies.
