Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.

The most precise clocks ever built can now detect gravity’s warping of time across a distance shorter than a pencil tip. That ...

Scientists have taken another giant step towards building the most precise clock ever imagined—one that could display not only the passage of time, but shifting rules of nature itself. An ...

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 decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

A portable atomic clock that has been successfully tested at sea could change the future of marine navigation.

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

Unlike other atoms (left), ytterbium-173 (right) has a large nuclear spin and a strongly deformed nucleus whose strong fields interact with the electron shell. This turns forbidden quantum jumps into ...
