China: World's largest centrifuge achieves 300 times Earth’s gravity

China has launched CHIEF1300, the world’s largest centrifuge by capacity, capable of generating up to 300 times Earth’s gravity (300G) on loads up to 22 tons. Located in Hangzhou at Zhejiang University’s Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF), this advanced research hub aims to simulate extreme environmental conditions such as earthquakes, tsunamis, deep-sea pressures, and geological processes. The facility includes multiple centrifuges and experimental setups, with plans to expand capacity further. By creating hypergravity fields far exceeding typical human experiences (e.g., roller coasters at 2G, astronaut launches at 5G), CHIEF enables accelerated and scaled-down modeling of natural phenomena, compressing timescales—such as simulating a century-long contaminant spread in just a few days. The CHIEF1300 centrifuge operates in a specially designed underground chamber with features like vacuum and cooling systems to ensure stable, safe operation while minimizing
