科学家对暗物质搜寻中的一项惊人结果深感好奇

科学家在南达科他州地下深处的实验设施中，记录到了一次无法用普通物质解释的亚原子粒子相互作用。这一异常现象引发了暗物质研究人员的关注，但目前尚无法确定是否探测到了暗物质粒子。

Dark matter is the invisible stuff that accounts for roughly 85% of the mass in the universe, and for decades, physicists have been trying to figure out what it's made of. Now an experimental facility located nearly a mile below ground in South Dakota has recorded a single interaction between subatomic particles that doesn't match what's expected from normal matter. Has a dark-matter particle been detected at last? It's too early to say, but the anomaly is definitely attracting attention from dark-matter detectives.
