Japan made the world's most accurate watch pair

Japanese scientists have created a pair of high-precision watches, which only take one second for 16 billion years.

" Optical network clocks in a cold environment " are more like computers than wall clocks. They are so high that today's technology is unmistakable.

A Tokyo University team led by Professor Hidetoshi Katori believes that the instrument could outstrip current atomic clocks that are used to determine "second units."

Japanese scientists use a special laser to hold strontium atoms in small mesh structures. Then it measured the oscillation frequency of strontium and used them as "pendulum atom".

The system should operate at a temperature of -180 degrees Celsius to reduce the impact of the surrounding electromagnetic waves and maintain the accuracy. The expert group connects two clocks in a month and estimates that there should be 16 billion new years of interruption per second. Meanwhile, for every 30 million years, cesium atomic clocks may appear similarly wrong.

According to AFP, the technology can be applied to global positioning systems by satellite, communication networks, or as the basis for many high accuracy technologies.

"By improving accuracy, we expect new discussions about reassignment of the second unit , " the team's statement said.
