The 2026 Doomsday Clock is ticking closer to midnight, signaling humanity edging to the "closest it has ever been to catastrophe" according to the Atomic Scientists, and the human race destroying ...
The most precise clocks ever built can now detect gravity’s warping of time across a distance shorter than a pencil tip. That achievement, remarkable on its own, has physicists asking a deeper ...
Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.
Atomic clocks have been around for nearly 80 years, but their successors—nuclear clocks—are ready to take the stage. Two independent studies, both uploaded as preprints, report reliable timekeeping ...
