论文摘要
驱动宇宙早期和迟到的加速扩张的机制是当今基本物理学中最引人注目的奥秘之一。理解早期和晚期加速的原因的途径取决于完全利用正在进行的调查，开发和演示新技术以及构建和操作新工具的途径。该报告在2030年代及以后提出了对宇宙调查计划的多方面愿景。宇宙调查解决了广泛的基本物理问题，因此是HEP实验组合中独特而有力的组成部分。
The mechanism(s) driving the early- and late-time accelerated expansion of the Universe represent one of the most compelling mysteries in fundamental physics today. The path to understanding the causes of early- and late-time acceleration depends on fully leveraging ongoing surveys, developing and demonstrating new technologies, and constructing and operating new instruments. This report presents a multi-faceted vision for the cosmic survey program in the 2030s and beyond that derives from these considerations. Cosmic surveys address a wide range of fundamental physics questions, and are thus a unique and powerful component of the HEP experimental portfolio.
