The universe is permeated by a network of filaments, sheets, and knots collectively forming a "cosmic web." The discovery of the cosmic web, especially through its signature of absorption of light from distant sources by neutral hydrogen in the intervening intergalactic medium, exemplifies the interplay between theory and experiment that drives science and is one of the great examples in which numerical simulations have played a key and decisive role. We recount the milestones in our understanding of cosmic structure; summarize its impact on astronomy, cosmology, and physics; and look ahead by outlining the challenges faced as we prepare to probe the cosmic web at new wavelengths.
宇宙中弥漫着一个由丝状结构、片状结构和纽结组成的网络，它们共同构成了一个“宇宙网”。宇宙网的发现，尤其是通过中性氢在星系际介质中对来自遥远光源的光的吸收特征而被发现，体现了推动科学发展的理论与实验之间的相互作用，也是数值模拟发挥关键和决定性作用的伟大范例之一。我们回顾了在理解宇宙结构方面的里程碑；总结了它对天文学、宇宙学和物理学的影响；并通过概述在准备以新波长探测宇宙网时所面临的挑战来展望未来。
