Multi-Ion Optical Atomic Clock Takes A Step Towards Changing The Definition Of A Second
Researchers have developed a new approach in optical nuclear clocks that land forth a major goal in skill : the redefinition of a irregular . The fundamental whole of time could soon be base on something beyond the transition of two hyperfine ground states of caesium , which has been the definition since 1967 . The first concrete stride in changing it has now happen . Over the last several years , researchers have shown that it is possible to design clocks 1,000 time more precise than the atomic pin clover that the original definition of the 2nd is base on ....
