论文摘要
本文回顾了普朗克协作的某些结果，并显示了如何计算与最后散射表面的距离，与观察到的最远物体的距离以及CMB等离子体中密度波动的最大半径。然后，它解释了这些距离以及众所周知的天文事实如何表明空间是平坦的或几乎平坦的，而暗能量是宇宙能量的69％。
This paper reviews some of the results of the Planck collaboration and shows how to compute the distance from the surface of last scattering, the distance from the farthest object that will ever be observed, and the maximum radius of a density fluctuation in the plasma of the CMB. It then explains how these distances together with well-known astronomical facts imply that space is flat or nearly flat and that dark energy is 69% of the energy of the universe.
