Connecting Quarks with the Cosmos

Advances made by physicists in understanding matter, space, and time and by astronomers in understanding the universe as a whole have closely intertwined the question being asked about the universe at its two extremes—the very large and the very small. This report identifies 11 key questions that have a good chance to be answered in the next decade. It urges that a new research strategy be created that brings to bear the techniques of both astronomy and sub-atomic physics in a cross-disciplinary way to address these questions. The report presents seven recommendations to facilitate the necessary research and development coordination. These recommendations identify key priorities for future scientific projects critical for realizing these scientific opportunities.Table of ContentsFront MatterExecutive Summary1 Introduction: Where We Are and Where We Can Be2 Foundations: Matter, Space, and Time3 How Are Matter, Space, and Time Unified?4 How Did the Universe Get Going?5 What Is the Nature of Dark Matter and Dark Energy6 What Are the Limits of Physical Law?7 Realizing the OpportunitiesAppendix A: Meeting AgendasAppendix B: Call for Community InputAppendix C: Project Proposals ReceivedAppendix D: Glossary and Acronyms
