Zhang Xinmin, member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC): In 2020, China will build the world's highest gravitational wave observatory Xinhua News Agency, Beijing, March 7 New Media (Reporter Jiang Fang Chenno Chen Gang) "The original gravitational wave is the gravitational wave produced by the Big Bang at the beginning of the universe."
, which is expected to be completed in China by 2020, will be the world's first primary gravitational wave observatory in the northern hemisphere.
, a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC) and a researcher at the Institute of High Energy Physics of the Chinese Academy of Sciences and chief scientist of the Ali Project, said.
2016, the U.S. Laser Interferon Gravitational Wave Observatory (LIGO) announced the discovery of gravitational waves, a discovery considered the largest breakthrough of the year for basic research.
, however, this is only the "preludes" of the discovery of gravitational waves, the confidence of countries in the detection and study of gravitational waves is high, a series of research plans to step up the layout.
, for example, in 2017, VIRGO, the European gravitational wave detector, will perform its first advanced joint operation with LIGO, helping researchers lock the source of gravitational waves into specific galaxies.
Zhang Xinmin, China's gravitational wave detection research has a clear road map.
First, space exploration, including the "Tai Chi Project" led by the Chinese Academy of Sciences and the "Tianqin Project" of Zhongshan University, and ground exploration, including the 500-meter sperical radio telescope FAST project in Guizhou under the auspices of the National Observatory, and the "Ali Project" led by the Institute of High Energy Physics of the Chinese Academy of Sciences, which detects the original gravitational waves.
Zhang Xinmin said that because the original gravitational wave is extremely weak, so the detection of it has been a difficult problem in the scientific community.
the original gravitational waves contain the mystery of the origin of the universe - was the universe caused by the Big Bang?It is important to detect primary gravitational waves and find suitable observation points.
according to Zhang Xinmin, there are only four places in the world suitable for cosmic microwave background radiation (CMB) detection: chile's Atakama Desert in the southern hemisphere, Antarctica, and Greenland in the northern hemisphere and China's Ali in Tibet.
"Now "Plan Ali is moving forward in all directions."
" Zhang Xinmin introduced, in February this year, the plan reviewed the design of the observation module, telescope construction program has also entered the evaluation stage, the plan will be formally constructed in early May, after completion and operation or can be the first time to achieve the northern hemisphere ground original gravitational wave observation, leading China's original gravitational wave research into the international frontier.
, the program is driving independent research and development of related technologies.
