Atomic clocks, combined with precise astronomical measurements, have shown that the length of the day is
Over the past few decades, the rotation of the Eartharound its axis, which determines the length of the day, has accelerated. As a result of this trend, the days were getting shorter; so, in June 2022, a record was set for the shortest day in the last half century. But despite this record, since 2020 this constant acceleration has been replaced by a slowdown - the days are getting longer again, and the reason for this remains a mystery.
The scientists added that the clock shows that inThere are exactly 24 hours in a day, which is the theoretical time it takes the Earth to complete one revolution. But this time is constantly changing - even earthquakes and storm events can play a role. A day is very rarely exactly equal to 86,400 seconds.
The reason for these changes is not clear. This may be due to climate change, natural disasters, the melting of glaciers or a volcano, as a result of which a huge amount of water has entered the atmosphere.
