Sciences. In 2020, the Earth was spinning (a little bit faster)

We have to believe that even Earth wanted to finish 2020 as soon as possible, because our planet’s rotation speed was a little faster last year. According to scientists interviewed for the British newspaper The Telegraph s The online scientific journal Phys.

They confirmed that July 19, 2020 was the shortest day ever recorded, with the planet spinning on itself at 1.4602 milliseconds less than a normal day, due to various factors: distance to the moon, snowfall levels, mountain erosion …

This acceleration will continue in 2021, depending on his work. As a result, 2021 should be 19 milliseconds in atomic time (the measure that regulates the clocks of our world).

Great first

Therefore, experts are considering using a leap second, a process sometimes used to adjust coordinated universal time in order to align atomic time with solar time.

Shortening the year by one second would be very new, because if physicists had indeed resorted to such a modification (27 seconds since 1970), every time it was a question of adding a leap second.
