The rotation of the planet varies slightly constantly depending on the movement of its core and the oceans andAtmosphere.
According to a report by the “Live Science” website, which specializes in scientific news, each day consists of 86,400 seconds, and we need a “negative leap second” in the next decade, otherwise the clocks will be out of sync.
And when Coordinated Universal Time or UTC, the official international method for displaying time, is not synchronized by more than 0.4 seconds, our clocks require an adjustment in the form of a “leap second” and the last time an adjustment was needed was on New Year’s Eve 2016, when an adjustment was added seconds at 23 hours 59 minutes and 59 seconds.
According to the US National Institute of Standards and Technology, scientists have added a “leap second” roughly every 18 months on average since 1972.
Scientists fear that the Earth could one day become unstable, as the Moon is moving further away from our planet.
The magazine “Earth, Planets and Space” indicated that this phenomenon can cause chaos in every aspect of our lives, as the gravitational rotation of the Earth and the Moon affects the sea, the sun, mammals and plant life, according to the British newspaper, “Daily Star”.
