The Hubble law discovered in 1929, i.e. the linear relation between the recession velocity of galaxies and their distance, is the cornerstone of modern cosmology and of the Big Bang model. In this model, the proportionality constant H0 in this relation, the so-called Hubble constant, is also the ratio of the expansion rate and size scale of the cosmos, the inverse ratio thus directly giving the age (and characteristic length) scale of the cosmos. To accurately determine H0 has thus been a major focus in observational cosmology and astrophysics over the past 90 years. However, the history of determining H0 has been full of systematic problems, inconsistencies and controversies from its very beginnings. The next few years are likely to be particularly interesting for further study of the discrepancy.

It is thus the perfect time now to bring together the experts in the various field of astronomy and astrophysics that are concerned with the determination of H0 and the implications of these results, and to discuss the most recent results, prospects, and possible implications, and provide them to a broader audience.
Do we have a Hubble constant crisis? Experts are discussing an old question full of current relevance for the understanding of our universe.
