英文摘要：

In this paper, the relation between astrophysics and physics is discussed briefly, and the relation between cosmology and physics is mainly focused. The fundamental idea of the Big Bang Cosmology is described and two most important predictions by the cosmology are discussed and quantitatively observed. Finally, two great progresses, namely Inflationary Cosmology and Accelerating Expansion, are discussed, which might lead to great breakthrough in fundamental physics.
