ScienceScienceAlert'The Most Accurate Clock in The World': Atomic Clock Just Set a New World Record
Scientists in Singapore have built the world's most accurate atomic clock using the element lutetium, which should lose less than a second over 300 billion years.
The time-keeping offered by your watch or phone may be good enough for day-to-day life, but scientists are much more ambitious in terms of precision, and use atomic clocks to measure slices of time as accurately as possible.
Researchers at the National University of Singapore have built an atomic clock based on the element lutetium that sets a new world record for accuracy, publishing their findings in Nature.
The clock measures a second with an uncertainty of under a ten-billion-billionth of a second, roughly four times more accurate than any previous record, and should lose less than a second over 300 billion years.
Lutetium's atomic structure makes it highly resistant to heat, magnetism and motion, meaning the clock stays stable across a wide range of environments, the researchers say.
