China has eclipsed its personal – and the US – document, constructing a monster underground hypergravity centrifuge that may mannequin eventualities with 1,900 instances the real-world gravitational drive of Earth, bending area and time with unprecedented energy.

Constructed by Shanghai Electrical Nuclear Energy Group as a part of China’s Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF), CHIEF1900 will quickly operate at 1,900 g-tonnes, surpassing the beforehand strongest centrifuge the CHIEF1300.
“We purpose to create experimental environments that span milliseconds to tens of 1000’s of years, and atomic to [kilometer] scales – below regular or excessive circumstances of temperature and strain,” Chen Yunmin, CHIEF’s chief scientist and a professor at Zhejiang College, informed South China Morning Submit. “It offers us the prospect to find completely new phenomena or theories.”
We first reported on the facility in 2024, when the dimensions of the venture was unveiled, however with solely the preliminary equipment in place. The spectacular CHIEF1300 got here on-line in September 2025, with the flexibility to generate as much as 1,300 g-tonnes of hypergravity. The brand new centrifuge is about 46% extra excessive in its capability.

Each centrifuges are used to mannequin intense gravity to compress time and scale in experiments – which primarily lets scientists simulate long-term or large-scale bodily phenomena similar to dam structural integrity, earthquake harm, landslides, nuclear waste storage and extra.
By rising efficient gravity, researchers can speed up years and even many years of structural and geological stress into just some hours, enabling experiments that might be impractical in the actual world.
The CHIEF1900 has been put in 49 ft (15 m) beneath Zhejiang College in Hangzhou, to be able to cut back the vibrational disturbance it’d trigger if contained in an above-ground facility. In the meantime, a vacuum-based coolant and air air flow circulation system offsets the extreme warmth generated by the centrifuges working at excessive speeds.
The hypergravity facility is reported to have price round US$285 million to construct and is anticipated to be a beacon of worldwide analysis, with the Chinese language group inviting scientists from world wide to make use of the know-how.
The CHIEF1900 is but to start conducting experiments, but it surely’s anticipated to be operational quickly.
