Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

The most advanced atomic clocks do not lose more than a second in 300 million years. That’s pretty accurate. But it turns out ...

What is the Doomsday Clock? It's 2025 and scientists have reset the clock closer to midnight and global catastrophe. Here's ...

The Doomsday Clock, a symbolic measure of humanity's proximity to catastrophic destruction, has been set at 89 seconds to ...

If you buy through a BGR link, we may earn an affiliate commission, helping support our expert product labs. Scientists from MIT have developed what they believe is the most accurate atomic clock ...

Time and Navigation from the National Air and Space Museum explores the surprising connection between time and place—if you want to know where you are, you need an accurate clock. And the Cooper ...

These optical clocks are still being assessed, but already now, some are 100 times more accurate than cesium clocks. They will therefore become the future basis for the worldwide definition of the ...

IN these days of accurate clocks and watches no one thinks of using a sun dial to tell the time of day. At best such an instrument can be right but four times a year, and in many places it can ...

However, compared to a quantum clock, atomic clocks are as accurate as a one-dollar antique pocket watch that's been whacked several times with a coal hammer. By measuring how atoms jump between ...

In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...
