Located 2,400 meters below Jinping Mountain, their research site is the world’s deepest underground laboratory. After reaching the foot of the mountain, it is a 10-minute drive before arriving at the lab. There are six layers of material outside the lab, including natural rock, 50-centimeter-thick concrete and other materials to keep nearly everything out. However, there is still something that cannot be kept out—the dark matter. According to NASA Science, only five percent of the universe is currently known. Dark energy fills 68 percent of the universe, and dark matter makes up about 27 percent. Human eyes can’t see either of the elements; and no one has detected them yet. Scientists are confident that dark matter exists. According to National Geographic, standard physics would suppose that stars orbiting at the edge of a galaxy travel slower than those near the center. However, what we see is that stars turn at nearly the same speed—no matter where they are. Scientists thus believe that stars are driven by the gravitational effect caused by dark matter. With the first dark matter search results from the lab published in 2021, Chinese researchers have successfully narrowed down the range when detecting these “ghosts”. A question remains—why do scientists need such a pure “environment”？ Professor Elisabetta, a physicist, told the Science X Network website that dark matter research has to happen deep underground to “cut out the cosmic(宇宙的) noise and radiation(辐射)”， for instance, cosmic rays(射线)which can be absorbed by rocks. If a lab is buried deep enough underground, the impact of cosmic rays may be reduced to zero. 语篇解读　本文为一篇说明文。文章介绍了在四川的一个大山深处， 有一个地下实验室， 中国科学家在实验室里不知疲倦地研究着暗物质。 细节理解题。根据文章第一段“Located 2,400 meters below Jinping Mountain, their research site is the world’s deepest underground laboratory.”可知， 这个地下实验室是世界上最深的地下实验室。 1．What’s the conclusion about the underground laboratory according to Paragraph 1?
