Abstract

Cosmology is undergoing a revolution. With recent precise measurements of the cosmic microwave background radiation, large galaxy redshift surveys, better measurements of the expansion rate of the Universe and a host of other astrophysical observations, there is now a standard, highly constrained cosmological model. It is not a cosmology that was predicted. Unidentified dark particles dominate the matter content of our Universe, and mysteries surround the processes responsible for the accelerated expansion at its earliest moments (inflation?) and for its recent acceleration (dark energy?). New measurements must address the fundamental questions: what happened at the birth of the Universe, and what is its ultimate fate?

摘要

宇宙学正在经历一场变革。随着近期对宇宙微波背景辐射的精确测量、大规模星系红移巡天、对宇宙膨胀率的更精确测量以及一系列其他天体物理观测，现在有了一个标准的、受到高度约束的宇宙学模型。这并非一个曾被预测到的宇宙学模型。身份不明的暗物质主导着我们宇宙的物质构成，并且围绕着宇宙早期加速膨胀（暴胀？）以及近期加速膨胀（暗能量？）背后的过程存在诸多谜团。新的测量必须解决这些基本问题：宇宙诞生时发生了什么，以及它的最终命运是什么？
