Cosmic Energy Budget Dark Matter Dark Energy Baryons Nuclear Science The mission: Explain the origin, evolution, and structure of the baryonic matter of the Universe
Cosmic Energy Budget Dark Matter Dark Energy Baryons • Three frontiers: • Fundamental symmetries & neutrinos • Nuclei and nuclear astrophysics • QCD Nuclear Science
Fundamental Symmetries & Cosmic History • What were the fundamental symmetries that governed the microphysics of the early universe? • What insights can low energy (E << MZ) precision nuclear physics studies provide?

What are the new fundamental symmetries? • Why is there more matter than antimatter in the present universe? • What are the unseen forces that disappeared from view as the universe cooled? • What are the masses of neutrinos and how have they shaped the evolution of the universe?
