中文简介:
时空曲率中的涟漪——“引力波”是由我们宇宙中一些最具活力和戏剧性的现象产生的,包括黑洞、中子星和超新星。在预测引力波存在近100年后,激光干涉仪引力波天文台(LIGO)的先进探测器首次探测到这种信号,开创了天文学的新纪元。这篇演讲将解释引力波的本质,描述宇宙中什么样的源可以产生引力波,解释如何探测引力波,以及这个新的天文学时代的未来可能是什么样子(和声音)。
课程简介: Ripples in the curvature of space-time – "gravitational waves" – are produced by some of the most energetic and dramatic phenomena in our universe, including black holes, neutron stars and supernovae. Close to 100 years after the prediction of the existence of gravitational waves, the advanced detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) detected such signals for the first time, starting a new era in astronomy. This talk will explain the nature of gravitational waves, describe what sources out in the Universe can produce them, explain how they are detected and what the future of this new era in astronomy might look (and sound) like.
关 键 词: 引力波; 黑洞; 天文
