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 ...

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.

Until now, the most accurate atomic clocks measured the vibration of caesium atoms between two energy states; one second is defined in Standard International units as the time it takes for one ...

For nearly 50 years, the length of a second has been defined in the same way. But researchers in Germany now believe they have found how to make the most accurate clock ever created, which keeps ...

Accounting for this effect can make future clocks even more precise, eventually leading to atomic clocks that lose only one second every 32 billion years – about two and a half times the age of ...

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.

New Atomic Clock Is So Accurate It Won't Lose 1 Second in 15 Billion Years. A few tweaks to the atomic clock make it hyper-accurate. By ABC News. April 22, 2015, 1:22 PM.

A study released Wednesday in Optica, the Optical Society’s research journal, is putting the pieces together about how to get an even better way to keep time.
