Scientists have a set a new record in accurate timekeeping, creating an atomic clock that won’t lose or gain a second in 15 billion years — a time span greater than the estimated age of the ...

Related article U.S. gets new, hyper-accurate atomic clock. ... Our understanding of a second is based on a system of technology developed in the 1940s and an agreement among scientists in 1967.

Scientists have created an atomic clock so precise that it won't lose or gain a single second in 15 billion years -- roughly the age of our universe.

Scientists have developed the most accurate atomic clock – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only improve services like ...

Atomic clocks use these frequencies — specifically, absorbing and emitting photons at regular intervals to keep time. They are the most accurate clock we have to measure time in seconds.

Together, these clocks will be so accurate they would lose less than one second over 300 million years – 10 times more accurate than the clocks aboard GPS satellites.

Known as a "strontium optical lattice clock", it is 100 times more accurate than caesium atomic clocks, the current standard for defining seconds, the precision-equipment producer said in a statement.

For now, this technical skirting of the Second Law of Thermodynamics is only theoretical. However, the authors note that this ...

New clock just dropped, but it’ll only drop a second every 30 billion years while in operation. That’s right: It’s the most precise, accurate clock yet built.

Together, these clocks will be so accurate they would lose less than one second over 300 million years – 10 times more accurate than the clocks aboard GPS satellites. Sign up to our Launchpad ...

In a nutshell, optical clocks are incredibly accurate instruments that measure the frequency of atoms after they’ve been excited by lasers. The atoms are first cooled to near absolute zero, then ...

Before the 1950s, the most accurate clocks used vibrating quartz crystals to keep time, but the seconds would drift on a daily basis. Essen's invention used the quantum properties of caesium atoms ...
