China Built an Underground Hypergravity Machine

China completed installation of the world's most powerful hypergravity machine, CHIEF1900, in Hangzhou, generating 1,900 g-tonnes of force to accelerate natural processes from centuries into days. The $285 million facility uses a 6.4-meter rotating arm to subject multi-ton samples to extreme forces, allowing researchers to test infrastructure failures, geological movements, and deep-sea engineering in compressed timeframes. This surpasses the previous record of 1,200 g-tonnes held by a US Army facility and will operate as a shared global research platform.
