For decades, nuclear clocks have existed as one of physics’ most tempting promises. A ...

A clock built from thorium-229 has crossed an important line, from a long-discussed concept to a working device. The shift ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a smartphone screen. Yet despite its constant presence, time remains one of the ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks. Scientists are developing next-generation atomic ...

Is Einstein's assumption about gravity and time correct? Researchers want to find out with the help of two clocks. And send them into space to find out.

Imagine you're trying to keep time by listening to a room full of people clapping. If everyone claps randomly, it’s hard to tell the rhythm. But if they clap in sync, the beat becomes clear and steady ...

Without precise time, the modern world collapses - from GPS to the electricity grid. And Switzerland is one of the clock ...

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 ...
