Even More Accurate Atomic Clock


Scientists announced last week that they have created the most advanced clock in the world. The clock,  described last 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.
