在这篇文章中，我们回顾并讨论了宇宙空洞的几个方面。空洞是宇宙中物质和星系大尺度分布的主要组成部分。它们对于理解宇宙网的出现的重要性是显而易见的。它们相对简单的形状和结构使它们成为提取各种宇宙参数值的有用工具，甚至可能包括暗能量的影响。也许最有希望和最具挑战性的是在其领域内发现的星系的问题。空洞的原始环境不仅为评估环境对星系形成和演化的作用提供了一个有希望的试验场，矮星系的缺乏甚至可能对宇宙结构形成的标准观点提出了严重挑战。
In this contribution we review and discuss several aspects of Cosmic Voids. Voids are a major component of the large scale distribution of matter and galaxies in the Universe. Their instrumental importance for understanding the emergence of the Cosmic Web is clear. Their relatively simple shape and structure makes them into useful tools for extracting the value of a variety cosmic parameters, possibly including even that of the influence of dark energy. Perhaps most promising and challenging is the issue of the galaxies found within their realm. Not only does the pristine environment of voids provide a promising testing ground for assessing the role of environment on the formation and evolution of galaxies, the dearth of dwarf galaxies may even represent a serious challenge to the standard view of cosmic structure formation.
