China has taken a significant step in high-precision timekeeping by mass-producing a fingernail-sized chip-scale atomic clock ...

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 ...

For decades, physicists have pursued a goal that sounds nearly impossible: to build a clock that keeps time using an atom's nucleus rather than the electrons orbiting it. "Having worked in this field ...

Two independent teams of scientists have created the first functional clocks that can keep ultraprecise time using the nuclei of a radioactive element ...

Considering that 90% of American adults own mobile phones, the practice of interrupting strangers to inquire about the time has almost completely disappeared. Since these devices are so prolific in ...

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 nearly a century, scientists around the world have been searching for dark matter—an invisible substance believed to make up about 80% of the universe's mass and needed to explain a variety of ...

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.

Humanity has used clocks since we became aware of the concept of time. And as technology has improved, so have our time-keeping methods. Today, many people rely on digital clocks to track the hours ...
