China prepares to launch a supergravity device that generates 1900 times gravity and enables 'space-time compression'

The supergravity device 'CHIEF1300' is currently in operation at Zhejiang University in China, and installation of 'CHIEF1900' has also begun from December 22, 2025. CHIEF1300 can apply 1,300 times gravity to a 1-ton object, and CHIEF1900 can apply 1,900 times gravity, and it is appealing that 'it can form a supergravity field and realize the space-time compression effect.'

The CHIEF1300 is housed in a circular laboratory covering approximately 230 square metres and has an output of 1300 g-tons, meaning it can apply 1300 times the weight to a one tonne object.

By generating hypergravity, it is possible to reproduce real-world disasters and geological changes in a small-scale laboratory. According to China Science and Technology, a Chinese government science portal, 'By generating 100 times the gravity in a laboratory, an object 100 meters long can be 'shrunk' to 1 meter. Furthermore, the process of transporting pollutants that would take 100 years can be 'shortened' to 3.65 days. This 'space-time compression' effect will contribute to the implementation of scientific missions and the research and verification of new technologies in engineering projects.'

CHIEF1300 began operation on September 29, 2025, and has already been used to test the safety of seabed mining by replicating the water pressure at a depth of 2,000 meters, simulate earthquake disasters to verify the seismic design of hydroelectric power plants, and simulate a 20-meter-high tsunami to collect data for site selection for offshore wind power plants. Preparations are also underway for CHIEF1900, which will be capable of outputting 1,900 tons, and its delivery to Zhejiang University was completed on December 22, 2025.
