China Develops Advanced Gravitational Device Capable of 1900 Times Earth's Gravity

China has announced a significant scientific advancement with the construction of a large-scale device designed to generate extreme gravitational forces underground. This new apparatus, known as CHIEF1900, is capable of simulating a gravitational force that is 1900 times stronger than that of Earth, surpassing the previous record held by the CHIEF1300.

The CHIEF1900 was developed by the Shanghai Nuclear Power Group and is part of the multidisciplinary CHIEF project focused on extreme gravitation. Its goal is to conduct scientific experiments that would typically take decades in nature, compressing them into just hours.

* Unprecedented Strength

Chen Yunmin, the project's lead scientist and a professor at Zhejiang University, stated that the aim is to create experimental environments that range from atomic scales to kilometers, and from fractions of a second to tens of millions of years under various natural or extreme conditions of pressure and temperature.

He added: "This project opens the door to discovering entirely new phenomena and theories that scientists have not previously considered."

* Accelerating Time and Structural Pressure

The CHIEF1300 was launched in September 2025 with a gravitational capacity of 1300 tons, while the new device boasts a 46% increase in capacity, allowing researchers to simulate the effects of extreme gravity to accelerate years or decades of structural and geological stress into just hours.

This device will enable the examination of the impacts of earthquakes, landslides, dam safety, radioactive waste storage, and other long-term or large-scale physical phenomena.

* Impressive Technical Specifications

The CHIEF1900 is installed at a depth of 15 meters beneath Zhejiang University in Hangzhou to minimize vibrations. It operates with a vacuum-based cooling system and a ventilation system to manage the heat generated by the high-speed centrifuges.

* Major Investment in Global Research

The project is estimated to cost around 285 million USD and is expected to become a leading international center for scientific research, inviting scientists from around the world to utilize this groundbreaking technology.

While the device has not yet begun experiments, its launch is imminent.

This breakthrough not only sets a new record for gravitational devices but also opens new avenues for studying space-time and extreme gravity, positioning China at the forefront of advanced scientific research.
