The unprecedented sensitivity and angular resolution of current and upcoming cosmological observations such as WMAP and Planck satellites provide us great opportunities to test cosmological theories. This makes it more urgent than ever that we are prepared with concrete models to infer properties of matter and gravity. A primary objective of this research program is to study the physics of the early universe which determines how our cosmos looks like today. An ideal theory of the early universe would be well-motivated from our understanding of fundamental physics, sets the right initial conditions for later stages of the cosmos without fine tuning, and also provides testable predictions that makes it falsifiable.

目前和即将进行的宇宙学观测，如WMAP和Planck卫星，其前所未有的灵敏度和角分辨率为我们提供了检验宇宙学理论的巨大机会。这使得我们比以往任何时候都更迫切地需要准备具体的模型来推断物质和重力的性质。这个研究计划的一个主要目标是研究早期宇宙的物理学，它决定了我们今天的宇宙是什么样子的。一个理想的早期宇宙理论将基于我们对基本物理的理解，为宇宙的后期阶段设定正确的初始条件，而不需要微调，还提供了可检验的预测，使其可以证伪。
