China to launch gravitational wave research project

gravitational wave, Chinese technology

Tianqin, China's domestic gravitational wave research project initiated by the Sun Yat-sen University in July 2015, is awaiting governmental approval.

由中山大学发起的中国本土引力波研究项目"天琴计划"于2015年7月立项,目前该项目正等待政府批复。

The US-based Laser Interferometer Gravitational-wave Observatory (LIGO) announced its ground-breaking discovery of gravitational waves on Thursday (Feb 11), which fulfilled the prediction of Albert Einstein's general theory of relativity a century ago.

周四,美国激光干涉引力波天文台宣布引力波研究取得重大突破,填补了一个世纪前爱因斯坦广义相对论的预测。

The new discovery has encouraged further studies into gravitational waves around the world, with China accelerating its domestic research, said Li Miao, dean of the Institute of Astronomy and Space Science of the university in China's Guangdong Province in the south. According to Li, Tianqin has already made progress on some key technologies and will be carried out in four stages over the next 15 to 20 years, including the last step of launching three high-orbit satellites to detect gravitational waves.

广东中山大学天文与空间科学研究院院长李淼称,这一新发现将激发全球范围内对引力波开展更深的研究,同时也将加速中国本土的引力波研究。他还介绍道,"天琴计划"已经在一些关键技术上取得了进展,该计划将在未来15到20年间通过四个阶段实施,最后阶段将发射三颗高轨道卫星来探测引力波。

The university plans to build a 5,000-square-meter observatory and a new lab occupying more than 10,000 square meters on Fenghuang Mountain in Zhuhai City, Guangdong Province. Chen Yanbei, scientist with LIGO, said Tianqin will study the gravitational waves in the space, which is different from research made by the US ground-based observatory.

中山大学计划修建一个5000平方米的天文台,并在广东珠海的凤凰山上新建占地10000平方米的实验室。LIGO科学家Chen Yanbei称,"天琴计划"将在太空中研究引力波,不同于美国通过地面天文台对引力波进行研究。

"Tianqin will likely collect more information about the phenomenon, as a larger black hole may be detected in space compared with one detected on the ground," said Chen.

"同地面探测相比,在太空中能探测到更大的黑洞,因此'天琴计划'将能搜集到更多关于这种现象的信息。"他说道。

Sun Yat-sen University is willing to co-operate with other institutions in China as well as around the globe to carry out its project, Li added.

李淼还说道,中山大学希望同国内乃至全球的其他研究机构合作,共同完成这一项目。
