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

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 ...

Keeping time is easy, keeping precise time is hard, but a new type of clock based on atomic nuclei has pushed time-keeping ...

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

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 ...

Atomic clocks are a class of clocks that leverage resonance frequencies of atoms to keep time with high precision. While these clocks have become increasingly advanced and accurate over the years, ...

Which atomic clocks are best? The first time zone, Greenwich Mean Time, was established in the late 1600s to assist sailors before the invention of the train and railway in the mid-1800s expanded the ...
