On October 3, 2017 (August 14, 2017 in the lunar calendar), three scientists won the Nobel Prize in Physics for their research on gravitational waves. The college announced in Stockholm at 11:50 local time on October 3, 2017 (17:50 Beijing time) that it would award the 2017 Nobel Prize in Physics to three American scientists, Rainer Weiss, Barry C.Barish and Kip S.Thorne, in recognition of their "decisive contributions to LIGO detectors and gravitational wave observations." Three scientists won the Nobel Prize in Physics for gravitational wave research. The Royal Swedish Academy of Sciences said in a press release that the 2017 Nobel Prize in Physics winners used their enthusiasm and determination to contribute to the success of the Laser Interferometer Gravitational-Wave Observatory (LIGO). Make a priceless contribution. The statement said that Weiss and Thorne, pioneers in this field of research, and Barish, the team leader who led the project to success, worked together to ensure that four decades of efforts yielded results and finally observed the existence of gravitational waves. On September 14, 2015, humans detected gravitational waves in the universe for the first time. In February 2016, Weiss and three other scientists announced the discovery to the world. In December 2015, January 2017, and August 2017, scientists detected gravitational waves three more times. In fact, as early as a century ago, Einstein predicted the existence of gravitational waves. The gravitational wave discovered came from the collision of two black holes, and it took 1.3 billion years for the gravitational wave to enter the field of view of the LIGO probe in the United States. Although the signal was extremely weak when it reached Earth, the discovery was enough to spark a revolution in astrophysics. Gravitational waves are a new way to observe the most intense events in space and are testing the limits of our understanding. Three scientists won the Nobel Prize in Physics for their research on gravitational waves. In the mid-1970s, Weiss had analyzed possible sources of background noise that interfered with measurements and designed a laser interference detector for this purpose to overcome this noise. Weiss and Thorne long believed that gravitational waves could be detected and would revolutionize our understanding of the universe. Einstein once described in his general theory of relativity that gravitational waves are everywhere, traveling at the speed of light, and filling the universe. Only when massive celestial bodies deep in the universe undergo violent activities such as acceleration, collision and merger can powerful gravitational waves be formed. Einstein once believed that it would never be possible to measure them, and the achievement of the LIGO project was to use a huge laser interference detector to measure a change thousands of times smaller than the nucleus of an atom, thereby observing the extremely weak gravitational wave signal when it reached the earth. So far, all electromagnetic radiation, including cosmic rays, and particles, including neutrinos, have been used to explore the universe. But gravitational waves are direct evidence of the destruction and changes of space-time itself. This is a new and unique field that opens up an unknown world. The hidden value of these discoveries is waiting for those who have successfully observed gravitational waves to interpret the information therein. Three scientists won the Nobel Prize in Physics for their research on gravitational waves. Rayna Weiss was born in Berlin, Germany in 1932 and is 85 years old. In order to escape political turmoil, the family moved to Prague, Czech Republic in late 1932, and then moved to the United States in 1938. He spent his youth in New York City and attended Colombia Grammar School. He received a bachelor's degree from MIT in 1955 and a doctorate from MIT in 1962. He taught at Tufts University in the United States from 1960 to 1962, was a postdoctoral scholar at Princeton University from 1962 to 64, and then joined the Massachusetts Institute of Technology to teach in 1964. Barry Barish was born in Omaha, Nebraska, USA in 1936. He is 81 years old. He received a bachelor's degree in physics in 1957 and a doctorate in experimental high-energy physics from the University of California, Berkeley in 1962. He joined Caltech in 1963. Barish played an important role in approving funding for the project by the National Science Board of the National Science Foundation and played an important role in the construction and delivery of LIGO. He also founded LIGO Scientific Collaboration, which currently has more than 1000 collaborators around the world. Kip Thorne was born in Logan, Utah, USA in 1940. He is 77 years old. He received a bachelor's degree from California Institute of Technology in 1962 and a doctorate from Princeton University in 1965. Thorne returned to Caltech in 1967 and was hired as an associate professor. Three years later, he was promoted to professor of theoretical physics.
