With measurements of the fluctuations in the cosmic microwave background radiation, their counterparts in large-scale structure in the form of baryon acoustic oscillations and the development of the cosmic distance ladder, the concordance model of cosmology is established as a robust standard model, able to describe the universe from seconds after the Big Bang to today and on spatial scales ranging from galaxies to the entire visible universe. The values of its free parameters are now pinned down to remarkable precision and future galaxy surveys will allow further improvement in precision.
