How does the Doomsday Clock work? Scientists warn we are closer to annihilation as clock moves closer to midnight
The 2026 Doomsday Clock, at 85 seconds to midnight, has been set closer to a global catastrophe than ever before. The clock ...
Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...
For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could ...
As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...
