Future cosmic surveys of large scale structure and the cosmic microwave background radiation will attempt to answer questions of fundamental physics: What is the nature of dark energy? Is cosmic gravity completely described by general relativity? Can we probe the inflationary epoch through primordial gravitational waves? What are the masses and hierarchy of neutrinos and are there additional relativistic degrees of freedom? We need to develop the theoretical, computational, and technological frameworks to address the questions. I also describe the Cosmic Visions process in the US, for what might come beyond the DESI-Euclid-LSST-WFIRST era for dark energy and the CMB.
