In 2020, the earth’s rotation will accelerate, we may need “negative leap seconds”



Another thing about 2020 is strange: the earth has accelerated.

The rotation speed of the planet usually drifts slightly, depending on the wind, changes in ocean currents, or shaking around the molten core of the earth. But in the past few decades, this has usually caused a microscopic slowdown of the rotation. The result of this is that every year (about half a year), we need to add “le seconds” to the atomic clock.

But in 2020, the situation has changed in the opposite direction-since 1960, our record is the fastest day of 28 days on record. This accelerates the rotation of the earth so much that the time lord in charge of the earth clock is considering adding “negative leap seconds”

;: kill time.

Incomplete Tenet, But I am still very excited. As “Life Science” wrote:

Peter Whitberry, a physicist at the National Physical Laboratory in the United Kingdom, said: “If the Earth’s rotation speed is further increased, it is likely to require negative leap seconds, but it is too early to say whether this is possible.” Tell the Telegraph. “There have also been international discussions on the future of leap seconds, and a negative leap second may be required to make the decision to permanently terminate as leap seconds.”
