Physicists have unveiled the world’s most accurate clock — a timepiece so reliable that it would take more than 260 billion years to lose a second.

Precision clocks are used in everything from satellite navigation to looking for dark matter. Ever more accurate clocks open fresh opportunities, such as mapping changes in Earth’s gravitational pull with exquisite precision, and could form the basis of a new definition of the second.

Never make assumptions

Hahah, thanks! Made me “nose-laugh” a couple of times!
