China’s new 'time-bending' centrifuge helps geologists compress centuries into days: Chinese scientists have built CHIEF1900, a powerful centrifuge that they claim can compress centuries of geological processes into days. The facility can simulate how pollutants migrate through soil over millennia or test a 3-meter dam model under the same stress as a 300-meter real-world wall, potentially helping researchers fast-forward through decades of environmental scenarios that are impossible to study in real time.
