🤯 OOPS SAYS
Incredible news for quantum physics, but absolutely devastating news for those of us who rely on "sorry, my clock is slow" as an excuse.
What actually happened
Scientists at the National University of Singapore have developed a highly precise optical atomic clock using lutetium. Researchers at the Centre for Quantum Technologies measured its frequency to 19 decimal places and reported an uncertainty of 1 × 10-19, which they said is the lowest recorded for an optical atomic clock. The team compared two separate clocks to test the measurement and achieved a comparison uncertainty of 5.7 × 10-19. The technology could support future research involving gravity, geophysics and fundamental physics while contributing to precision measurement and timekeeping
