中文简介: | 时空弯曲中的涟漪-“引力波”-是由我们宇宙中一些最充满活力和戏剧性的现象产生的,包括黑洞,中子星和超新星。在预测了引力波的存在后将近100年,激光干涉仪引力波天文台(LIGO)的高级探测器首次检测到了此类信号,从而开创了天文学的新纪元。这次演讲将解释引力波的性质,描述宇宙中哪些来源会产生引力波,解释引力波是如何被检测到的,以及这个天文学新时代的未来会是什么样(和听起来)。 p> |
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. |
