The clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say. A new atomic clock is one of the world’s best timekeepers, ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But ...

A tomic clocks, which power GPS, online transactions, and data networks, just became more precise. MIT physicists have developed a technique that doubles the accuracy of optical atomic clocks by ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

For the first time, scientists have dated dinosaur eggs that lay buried in rock for millions of years, using a groundbreaking new ‘atomic clock for fossils’ method. During the Cretaceous period, Earth ...
