In this paper we investigate the impact of radionactivity on the evolution of the universe. We demonstrate that whether the radion overcloses the universe, constitutes the dark matter, is the inflaton, the curvaton, or does not

His experiments shaped our understanding of the world of particle physics. Included in the long list of his accolades was the 1988 Nobel Prize in Physics, which he shared with Melvin Schwartz and Jack Steinberger for the discovery that the muon neutrino is distinct from the electron neutrino. Among his many science leadership roles, he served for a decade as Director of Fermi National Accelerator Laboratory. Lederman was a spokesperson and champion for science and one of the most visible physicists of his generation. In his remarkable career Lederman journeyed from his youth in the Bronx, NY, to the directorship of Fermilab in Batavia, IL, to become an international proponent for physics beyond any one institution.

We will discuss the three pillars of the consensus cosmology -- dark matter, dark energy and inflation -- and their connections to fundamental physics and speculate about "all that".
