This atomic clock is so precise it can detect how gravity changes time. Scientists now want to take it outside the lab and measure tiny shifts across Earth

Researchers at Singapore's Centre for Quantum Technologies have developed a highly accurate lutetium-based atomic clock. This clock has a reported frequency uncertainty of 1 10, making it one of the most precise clocks available. The team successfully demonstrated the clocks sensitivity to minute differences in gravitational potential. Future plans involve creating a transportable version of the clock for various scientific applications.
