在这篇文章中，我们回顾了宇宙膨胀理论，特别关注它在非常小的物理学和非常大的观测之间提供的美丽联系。我们解释了如何在暴胀时代的量子力学波动成为宏观密度波动，在宇宙微波背景（CMB）留下明显的印记。我们描述的物理各向异性的CMB温度和偏振，并讨论如何CMB观测可以用来探测原始宇宙。
In this article we review the theory of cosmological inflation with a particular focus on the beautiful connection it provides between the physics of the very small and observations of the very large. We explain how quantum mechanical fluctuations during the inflationary era become macroscopic density fluctuations which leave distinct imprints in the cosmic microwave background (CMB). We describe the physics of anisotropies in the CMB temperature and polarization and discuss how CMB observations can be used to probe the primordial universe.
