The current model of the universe, based on an inflationary beginning and the content presently dominated by dark matter and dark energy, has survived a decade of intense scrutiny. It is in an excellent agreement with the three main kinds of astronomical data available to us today -- fluctuations in the cosmic microwave background (CMB), the large scale distribution of galaxies, and the dimming of distant supernovae. However, the origin of inflation and its connection to the rest of high energy physics remains unresolved, as does the nature of dark matter and dark energy. Over the next decade, qualitative improvements are expected in all three types of data. Motivated by this prospect, our proposal focuses on two main directions. In one, we will concentrate on new observational tests of dark energy or, more generally, the gravitational physics causing the apparent acceleration of the universe. The other focus will be on processes that took place at high energies and whose observational signatures can either be confused with those of inflation or help to discriminate among different models of inflation.

宇宙的当前模型基于通货膨胀的开端和目前以暗物质和暗能量为主的内容，经过了十年的严格审查。这与当今我们可用的三种主要天文数据是一个很好的一致性 - 宇宙微波背景（CMB）的波动，星系的大规模分布以及遥远的超新星的变暗。但是，通货膨胀的起源及其与其他高能物理的联系仍然无法解决，暗物质和暗能量的性质也是如此。在接下来的十年中，预计所有三种类型的数据都将进行定性改进。在这一前景的推动下，我们的提议集中在两个主要方向上。在其中，我们将集中精力进行黑暗能量的新观察测试，或者更普遍地是引起宇宙明显加速的重力物理学。另一个重点将放在高能以高能的过程上，其观察性签名可以与通货膨胀相混淆，或者有助于区分不同通货膨胀模型。
