A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with ...

Possibly originating with the English poet Geoffrey Chaucer's "time and tide wait for no man," the idea that time waits for ...

A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to ...

The atomic clock used in modern timekeeping uses lasers to manipulate atoms of cesium-133 along a frigid shaft. Then microwaves blast into a huddled bundle of these atoms, and triggers their ...

Over the last several years, researchers have shown that it is possible to design clocks 1,000 times more precise than the atomic clocks that the original definition of the second is based on ...

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 – ...

The National Institute of Standards and Technology (NIST) has set a new record by developing the world's most accurate clock, an atomic device with 19 decimal places of precision.

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 ...

The atomic clock is an optical lattice that controls strontium atoms. Photo: K. Palubicki/NIST New clock just dropped, but it’ll only drop a second every 30 billion years while in operation.

Researchers have built an atomic clock that is more precise and accurate than any previous clock. For the first time, the clock can detect the effects of gravity predicted by the theory of general ...

The Doomsday Clock of the Bulletin of the Atomic Scientists, set at 89 seconds to midnight, is displayed during a news conference at the United States Institute of Peace, Tuesday, Jan. 28, 2025 ...
