On the largest scales, matter is strung out on an intricate pattern known as the cosmic web. The tendrils of this web should reach right into our own cosmic backyard, lacing the Galactic halo with lumps of dark matter. The search for these lumps, lit up by stars that formed within them, is a major astronomical endeavor, although it has failed to find the huge expected population. Is this a dark matter crisis, or does it provide clues to the complexities of gas physics in the early universe? New technologies in the coming decade will reveal the answer.
在最大的尺度上，物质分布在一种被称为宇宙网的复杂结构上。这张网的丝状结构应该一直延伸到我们自己的宇宙后院，将银河系晕圈与暗物质团块交织在一起。寻找这些被其中形成的恒星照亮的团块是一项重大的天文学研究工作，尽管尚未找到预期数量众多的团块。这是一场暗物质危机，还是为早期宇宙中气体物理学的复杂性提供了线索？未来十年的新技术将揭示答案。
