America invented the world's most accurate watch

According to the journal Science, American scientists have invented the world's most accurate watch with 10 times the accuracy of any watch.

>>> The device is more accurate than the atomic clock

The optical network clock is made of the Ytebi (Yt) element that represents the breakthrough, giving a new level of clock stability. "Measuring more than a hundred years, this clock is accurate to a few nanoseconds," said Andrew Ludlow, a researcher at the Institute for Standards and Technology in Boulder, Colorado .

If mechanical clocks use pendulum motion to calculate time, atomic clocks use electromagnetic radiation emitted at precise frequencies to stimulate the electrons of the moving cesium atom. .

Physicists have used 10,000 rare earths, cooled down to 10 microkelvin (10 parts per million by 1 degree) to make the Ytebi clock. It is placed in an optical fence made of laser light. The watch has high stability due to the large amount of atoms.

The stability of the optical network clock, made from the Ytebi element, has opened the door to a number of interesting applications in practice, as well as bringing advanced technological applications across the track. Common times like positioning systems, magnetic fields and temperatures.

In addition, scientists hope to use the Ytebil optical network meter to examine other theories, seeking an explanation for the relationship between gravity and time. "Today, many scientists believe that relativity is incompatible with other physical theories," said Ludlow .
