Scientists propose a new atomic clock experiment that could reveal whether time itself follows the strange rules of quantum ...

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could ...

Add Yahoo as a preferred source to see more of our stories on Google. The Bulletin of the Atomic Scientists members, from left, Jon B. Wolfsthal, Asha M. George and Steve Fetter reveal the Doomsday ...

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.

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 ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

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 ...

The last time that digital clocks read 23:59:60 occurred on December 31, 2016. In an update from the International Earth ...
