From April 17 to 22, 2021, the six-day seminar on "Opportunities and Challenges in Basic Physics in the Era of Gravitational Waves" was successfully held at HIAS. Academician Wu Yueliang, Vice President of the University of Chinese Academy of Sciences, Academician Wang Jianyu, President of HIAS, Academician Hu Wenrui of the Institute of Mechanics, Chinese Academy of Sciences, Academician Cai Ronggen, Director of Institute of Theoretical Physics, Chinese Academy of Sciences, Academician Ma Yugang, Deputy Director of Shanghai Institute of Applied Physics, Chinese Academy of Sciences, and more than 100 experts and scholars from universities and research institutes across the country in gravitational wave physics research gathered together to explore and look forward to the opportunities and challenges of China's basic physics research in the era of gravitational waves in the future.

Academician Wang Jianyu, President of HIAS, delivered an opening speech for the meeting. Wang Jianyu first extended a warm welcome to the guests and then introduced the background and current situation of HIAS. President Wang Jianyu also described the long-term planning for the construction of the permanent campus in the future. It is believed that HIAS, as a branch of the Chinese Academy of Sciences system by the West Lake, will continue to inherit and carry forward the distinctive systems of scientific research, talent training, and innovation and entrepreneurship of the Chinese Academy of Sciences and the University of Science and Technology of China.

Later, Academician Wu Yueliang, Vice President of the Chinese Academy of Sciences and Dean of the School ofFundamental Physics and Mathematical Sciences, HIAS, delivered a report entitled "Program of Gravitational Wave Detection in Space". In the report, Wu Yueliang first reviewed the significance, history, and technical challenges of gravitational wave detection, then introduced the "three-step" strategy of gravitational wave detection in the "Taiji Program in Space" and the breakthrough progress made by "Taiji-1", and finally described the research progress on the basis of super-unified field theory.

Next, the participating experts made wonderful academic reports on their respective research fields, including the Current Situation and Prospects of Gravitational Wave Detection and Other Astronomy Observations; Gravitational Theory, Quantum Gravity, and the Nature of Gravity Beyond Einstein's General Relativity; the Formation of Dark Matter, Dark Energy and Black Holes and the Generation of Universe Inflation; Properties of Strongly Interacting Matter and Neutron Star ( Dense Star) Physics Under Extreme Conditions; Evolution and Numerical Simulation of Gravity Cosmic State. Teachers and students attending the meeting benefited a lot from the scientific research progress in nuclear physics, cosmic gravity, and experimental testing.

At the end of the report, Ma Yongliang, Vice President of theSchool of Fundamental Physics and Mathematical Sciences, summarized the meeting. Ma Yongliang introduced the origin of this meeting. In November 2019, the construction of theSchool of Fundamental Physics and Mathematical Sciences, HIAS was launched. The main goal was to carry out scientific research and talent training in "quantum cosmic physics", and then HIAS established the Gravitational Cosmic Taiji Laboratory. Ma Yongliang, together with several colleagues, launched the academic conference from the scientific goals of the School ofFundamental Physics and Mathematical Sciences and the Taiji Laboratory. It is hoped that this conference can build a platform for free exchanges on key technologies of space gravitational wave detection and discussion on quantum cosmic physics. Finally, Ma Yongliang expressed his heartfelt thanks to all the people and groups who supported the conference.

The conference was co-organized by HIAS, the Institute of Theoretical Physics, Chinese Academy of Sciences, and the International Center for Theoretical Physics (Asia-Pacific Region), and undertaken by the School ofFundamental Physics and Mathematical Sciences, HIAS. The conference was supported by the organizers, the Chinese Academy of Sciences, the National Natural Science Foundation of China, and the Ministry of Science and Technology of the People's Republic of China. The successful holding of this conference has set up a good platform for domestic experts and scholars in this field to discuss and exchange freely. It is hoped that this conference will contribute wisdom and strength to understanding the gravitational universe and making major international breakthroughs in the field of space exploration in China.
