By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that ...

First dreamed up decades ago, the world's first nuclear clocks are set to improve quickly, becoming more precise and aiding ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, ...

World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

But physicists have long dreamt of even better clocks that run on atomic nuclei, which are less sensitive to environmental ...

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.

When it comes to navigation in outer space, keeping precise time is incredibly important, that's why NASA needs to use ...

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 ...

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 are established as the most precise timekeepers created. Atomic clocks work by deploying lasers to measure the vibrations of atoms (electromagnetic signals). By atoms oscillating at a ...
