Ceasul atomic cu cea mai mica eroare

Ceasul atomic prezentat mai jos ar avea o pierdere de câteva fracțiuni de secundă cam în 5 miliarde de ani:

N-am înțeles prea multe din ce a zis meseriașu' dar am retinut urmatoarele:
"A newly refined strontium based timepiece takes the mantle of the World’s most accurate clock as researchers claim it would neither gain nor lose time over the course of 5 billion years. The JILA clock’s strontium atoms are bathed in an extremely stable red laser light, exciting them to jump between energy levels. These jumps, which occur some 430 trillion times per second, represent the quantum ticks of this hyper accurate device and result in the timepiece’s incredible performance."
O sa avem un ceas foarte precis ... când întârziem !
