Time dilation is a measurable change in the passage of time caused by differences in gravitational potential, a key prediction of general relativity. Recent advances in atomic clock precision allow ...

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 ...

If, like me, you can't go a day without making sure your watch is synced to the second, you'll be delighted to learn that a new atomic clock has broken the record with an accuracy of 5.5 x 10⁻¹⁹ – ...

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

Quantum sensing specialist Aquark Technologies has completed a second trial of its AQlock atomic clock system, facilitated by the Disruptive Capabilities and Technologies Office (DCTO) of the UK Royal ...

EUROPE — Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn’t lose or ...

Abstract: We report on measurements of frequency shifts in a microwave cesium vapor cell atomic clock based on coherent population trapping (CPT). The dependence of the clock frequency on numerous ...

It's Memorial Day, Short Wavers. This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend ...
