Redefining Time: US Builds World’s Most Accurate Atomic Clock Ever

Researchers at JILA, a US research institute, have developed a new light-based atomic clock that is so precise that it can measure the smallest effects predicted by Einstein’s general theory of relativity. The clock will lead to a more precise definition of a second and could even lead to the discovery of new underground mineral … Read more

The world’s most accurate and precise atomic clock pushes boundaries in physics

An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh vacuum environment, meaning there is almost no air or other gases present. This vacuum helps preserve the atoms’ delicate quantum states, which are fragile. The red dot you see … Read more
