全球定位系统(GPS)已经成为我们生活中不可或缺的一部分,无论是在都市导航,还是在山区寻路,都需要用到GPS装置。对物理学家来说,全球定位系统也可能成为直接探测暗物质的工具。近日,美国内华达大学雷诺分校的安德雷·德雷维安科及其同事,来自加拿大维多利亚大学和理论物理学周边研究所的马西姆·波斯彼洛夫提出了一个探测暗物质的方法。利用GPS卫星和其他原子钟网络,比较原子钟显示的时间差异,寻找受暗物质影响的线索。“尽管已经有了扎实的观测证据,但暗物质依然
Global Positioning System (GPS) has become an integral part of our lives, whether it is in the city navigation, or in the mountains to find ways, need to use GPS devices. For physicists, the GPS may also be a tool to detect dark matter directly. Recently, Andrey Trevánko at the University of Nevada in Reno, and his colleagues, Massim Persysirov from Victoria University of Canada and the Permalloy Institute of Theoretical Physics proposed a method to detect dark matter. Use GPS satellites and other atomic clock networks to compare time differences displayed by atomic clocks to find clues that are affected by dark matter. ”Despite the solid observational evidence, dark matter remains
