The optical lattice clock shines lasers on atoms to measure time |
Scientists say they have found a more accurate way to measure time. We currently use atomic clocks to count the seconds, but tests on an alternative atomic timekeeper have revealed that it is more precise.
The French researchers said the clocks, which are called optical lattice clocks, lost just one second every 300 million years.
Writing in Nature Communications, the team said they offered a better system for defining the second.
