The Hubble Constant Controversy: Status, Implications and Solutions

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.

This NASA/ESA Hubble Space Telescope image shows a massive galaxy cluster glowing brightly in the darkness. Despite its beauty, this cluster bears the distinctly unpoetic name of PLCK_G308.3-20.2. Galaxy clusters can contain thousands of galaxies all held together by the glue of gravity.

The Hubble Space Telescope is a joint ESA/NASA project and was launched in 1990 by the Space Shuttle mission STS-31 into a low-Earth orbit 600 km above the ground. During its lifetime Hubble has become one of the most important science projects ever. credits ESA

Resembling a wizard’s staff set aglow, NGC 1032 cleaves the quiet darkness of space in two in this image from the NASA/ESA Hubble Space Telescope. NGC 1032 is located about a hundred million light years away in the constellation Cetus (The Sea Monster).
