Will the clock be only one 120 seconds wrong for 14 billion years?

Some scientists propose to replace the atomic clock with a nuclear clock, because the nuclear clock only runs one-thirds of a second within 14 billion years - the time equivalent to the life of the universe.

The NIST-F1 atomic clock is the time standard in the US that is expected to deviate one second over a period of over 100 million years.

In simplest terms, the atomic clock uses electrons orbiting an atom - in the case of NIST-F1, cesium 133 acts as a pendulum.

Researchers at the University of New South Wales, Georgia Institute of Technology (USA) and the University of Nevada (USA) said that nuclear physics is more accurate than atomic physics. The clock operates on the principle of nuclear physics nearly 100 times more accurate, most atomic clocks are being used today.

'By using lasers to direct electrons in a certain direction, it is possible to use a neutron rotating around an atomic nucleus like a clock pendulum, forming a nuclear watch ,' said Prof. Victor Flambaum. at New South Wales University, explained.

In atomic clocks, electrons make samples relatively loose, so they are easily affected by external disturbances, affecting their oscillation rate. But nuclear clocks maintain accuracy for a longer time because neurons are kept very close to the nucleus.

According to GS. Flambaum, a nuclear clock, will allow scientists to test basic physics theories with unprecedented precision, and will create an unparalleled device for applied physics research. '
