在美国南达科他州地下深处的一座前金矿中，研究人员利用充满液态氙的探测器记录到一次罕见的原子核碰撞，并留下无法解释的异常能量信号，科学家认为这可能是迄今为止最令人信服的暗物质物理证据。

暗物质约占宇宙物质的85%，因不与光相互作用而难以直接观测，其热门候选粒子为弱相互作用大质量粒子（WIMPs）。在长达220天的观测中仅记录到这一次异动，虽然统计数据尚不足以正式宣布发现新粒子，但已排除了常规背景杂讯干扰。

研究团队已将成果发布为预印本并在学术会议上进行分享，初步模型估计该粒子质量约为质子的200倍；尽管科学家保持谨慎态度，但若能证实其为暗物质碰撞，将为人类揭示暗物质性质及其与常规物质的交互作用带来重大突破。

Deep underground in a former gold mine in South Dakota, researchers using a detector filled with liquid xenon recorded a rare atomic nucleus recoil with an unusual energy signature, which scientists believe could represent the most convincing physical evidence of dark matter to date.

Dark matter accounts for roughly 85 percent of the universe's matter but remains invisible, with Weakly Interacting Massive Particles (WIMPs) standing as a primary theoretical candidate; although only a single such anomaly was detected across 220 days of observation—insufficient for a confirmed discovery—the signal successfully withstood rigorous background noise filtering.

The research team has released their preliminary findings as a preprint and shared them with the scientific community, calculating that the potential candidate particle would be roughly 200 times more massive than a proton, which could unlock unprecedented insights into dark matter's fundamental properties if verified.
