China has quietly built a machine that bends one of the most stubborn limits in physics research: gravity itself. By pushing hypergravity to levels roughly half again higher than the previous world ...

China has built a machine so extreme that its designers say it can squeeze centuries of geological change into a few days of lab time, effectively compressing the way matter experiences time and space ...

China has completed construction of the world’s most powerful hypergravity machine, a device designed to compress space and time to simulate extreme events like dam and earthquake disasters. The ...
