Superstring theory suggests that our universe was created by bubble nucleation in eternal inflation. We constructed a non-perturbative formulation for such a universe. We showed that there are various phases in eternal inflation, and pointed out that the properties of our universe depend on the phase. We also proposed a new mechanism for the generation of temperature fluctuations of cosmic microwave background radiations. Superstring theory suggests that black holes are described by quantum mechanics of matrices. We computed correlation functions of such a matrix model by using analytical and numerical methods.

超弦理论认为，我们的宇宙是由气泡在永恒膨胀中成核而产生的。我们为这样的宇宙构造了一个非微扰公式。我们证明了永恒膨胀有不同的阶段，并指出我们宇宙的性质取决于这些阶段。我们还提出了宇宙微波背景辐射温度涨落产生的新机制。超弦理论认为黑洞是用矩阵的量子力学来描述的。我们用解析和数值方法计算了这种矩阵模型的关联函数。
