Tickety-Tock! An Even More Accurate Atomic Clock
Scientists announced this week that they have created the most advanced clock in the world.
The clock, this week in the journal Nature, is so precise that it would neither lose nor gain one second in about 5 billion years of continuous operation. That’s pretty good, considering that the Earth itself is only around 4.5 billion years old.
Since the 1960s, official timekeeping has been based on the natural oscillations of atoms. And scientists just continue to come up with better designs for so-called atomic clocks. A few years ago, a team unveiled a clock that would neither gain nor lose one second in about 3.7 billion years.
