Depending on its mass density, the geometry of the universe could be flat, open, or closed. In his research commentary, Kamionkowski discusses recent and future observations that consider these basic cosmological questions. In a related research article, Gawiser and Silk describe a comparison of different models for what makes up the mass of the universe; an accompanying research commentary by Primack discusses in particular the role of neutrinos in cosmology.
