abstract:
Some insights about the present Hubble tension are given from a perspective of the observational astronomy. The difference between the local (based on supernova) and the global (based on the LCDM model) values of the Hubble parameter may indicate a need for a revision of the LCDM model – a „new” physics. However, another likely cause is simply an underestimation of systematic uncertanties.
