摘要 (Abstract)：

This is the first lecture on the Gravity and Cosmology. Further detail of the lecture will be provided during the next year, e.g. summer. In this first lecture we will give an overview picture, providing the basic obseravational structure of the universe, and then critical observational evidences that lead to the standard model of the so-called lambda CDM model. We also explain briefly some challenging observations to that standard lambda CDM picture.
