A Record-Breaking Clock Won’t Lose a Second For Another 15 Billion Years

1000

It’s about time!

From The Guardian:

Physicists have said they have fine-tuned an atomic clock to the point where it won’t lose or gain a second in 15bn years – longer than the universe has existed.

The “optical lattice” clock, which uses strontium atoms, is now three times more accurate than a year ago when it set the previous world record, its developers reported in the journal Nature Communications.

The advance brings science a step closer to replacing the current gold standard in timekeeping: the caesium fountain clock that is used to set Coordinated Universal Time (UTC), the official world time.

“Precise and accurate optical atomic clocks have the potential to transform global timekeeping,” the study authors wrote.
