More than 30 billion years of error less than 1 second!The Chinese Academy of Sciences develops a new generation of light clock

Science Fiction Network June 17 (Wang Ziyu) Time is the continuous and sequential performance of the eternal motion of material, the change of change. In nature, the rotation and revolving of the earth generate the earliest time. With the development of society, the accuracy requirements of human time are getting higher and higher, and there are various clocks. At present, the latest light clock developed by the Chinese Academy of Sciences can achieve more than 30 billion years of error for less than 1 second.

In recent years, the research team of the Chinese Academy of Sciences has been committed to developing various advanced atomic clocks. After more than 10 years of development, atomic 铯 fountain clocks, cold atoms, light bells, and international first laser pumping Xiaoyuzhong bells and other products.

The latest development of the light clocks this time is the best one. According to scientists, the light bell is a high -performance forward -looking atomic clock and a benchmark atomic clock in the future, and its accuracy has also greatly improved compared with other products. Taking the 铯 Atomic fountain clock as an example, it can achieve 60 million years of accumulation errors for less than 1 second, and the light clock can achieve more than 30 billion years of error less than 1 second.

Such a high -precision bell is not more time on time to go to work, and its use is more widely used, such as high -precision clocks in the navigation system. In addition, high -precision light clocks can also be used in the launch of missiles, satellites and spacecraft, and providing high -precision time signals such as measurement and control and guidance.

At present, scientists are trying to send light clocks to space, but many technical problems are solved.
