?Does a day extend to 25 hours? ...A German study says it is possible, but when will that happen
Does a day extend to 25 hours? 13-613
A study by scientists from the German Technical University of Munich revealed that a day on planet Earth could become 25 hours instead of 24 hours, a discovery that shows the great progress that science has achieved in understanding the Earth’s rotation through rotational dynamics.
The Earth completes one revolution around its axis once every 24 hours, which represents one day, but the Earth’s rotation was not always constant, contrary to popular belief, and early in the planet’s history, the rotation may have been less than 10 hours. This discrepancy is due to the heterogeneous composition of the Earth, which is a mixture of different solids and liquids, each of which affects the speed of the planet's rotation.
“It could take 200 million years.”
In its report on the subject, the British newspaper “The Sun” stated, “It may take millions of years before another hour is added, but Earth days are actually getting longer for years, as they are getting longer by about 1.8 milliseconds every century.”

She reported that this is an increase of one minute every 3.3 million years, which means that it may take "200 million years before another hour is added to the Earth's day."
According to the study, the Moon appears to be responsible, because the friction resulting from the tides slows down the Earth's rotation over time, as the Earth receives a signal from a star 16,000 light-years away.
When the Earth rotates on its axis, this determines the amount of sunlight that crosses its surface, thus affecting the length of days, but the Moon's gravity pulls on the side of the Earth closest to it, which causes tides and causes the planet to swell.

For his part, Ulrich Schreiber, a professor from the Technical University of Munich, said: “Fluctuations in circulation are not only important for astronomy, but we also urgently need them to create accurate climate models and better understand weather phenomena such as El Niño.”
