Our most recent generation of cosmology experiments, such as the Planck satellite and observations of distant supernovae, has reduced all of cosmology to the very precise measurement of eight parameters. This relatively simple model seems complete with no hints of additional elements required to explain the entire evolution of the universe from the big bang to some far distant future. These recent results include such things as the precise measurement of the contributors to the overall mass–energy density of the universe. We know with great precision the amount of dark energy, dark matter, neutrinos, baryons, etc., in the universe today. What we do not know is exactly what most of these things really are.
