Description

I will review the essence of the Hubble tension, its current observational status and the three classes of theoretical models that attempt to address it. Then I will focus on the level of the tension in redshift bins as expressed by the mismatch between distances measured by BAO data and by SnIa data calibrated respectively by the CMB sound horizon scale and by the Cepheid based distance ladder. The variation of the tension with redshift will be discussed and its possible implications for theoretical models will be analysed.
