Ultrahigh energy cosmic rays create black holes in scenarios with extra dimensions and TeV-scale gravity. In particular, cosmic neutrinos will produce black holes deep in the atmosphere, initiating quasihorizontal showers far above the standard model rate. At the Auger Observatory, hundreds of black hole events may be observed, providing evidence for extra dimensions and the first opportunity for experimental study of microscopic black holes. If no black holes are found, the fundamental Planck scale must be above 2 TeV for any number of extra dimensions.
在具有额外维度和 TeV 尺度引力的情形下，超高能宇宙射线会产生黑洞。特别是，宇宙中微子将在大气层深处产生黑洞，引发远超标准模型速率的准水平簇射。在奥格天文台，可能会观测到数百个黑洞事件，这将为额外维度提供证据，并为微观黑洞的实验研究提供首个机会。如果未发现黑洞，那么对于任意数量的额外维度，基本普朗克尺度必定高于 2 TeV。
