Everyone is congratulating the recent Nobel Prize winners, whose work uses observations of distant supernovae to attempt to show the existence of universal acceleration. Let's not forget that supernova studies of cosmology are all based on a theory (General Relativity) that has huge problems - as demonstrated first by Zwicky in the 1930s, again by Rubin et al in the 1970s, and continually since. But instead of coming up with a new theory of gravity that fits the large-scale data, the community has continually propped up GR by introducing free parameters. These include exotic forms of matter and energy for which there is no theoretical understanding and no observational evidence, despite decades of searching. GR works well within the solar system. But time and time again serious, intractable problems have emerged on large scales. Not only does the metric have no clothes, we do not even know its shape. Ironically, were he still with us, Einstein would be first to roll up his sleeves.
