Since its inception Earth 4.5 billion years ago The years The days were getting longer more time. This happens because the speed at which the Earth rotates on its own axis slows down at certain times.
1.5 billion years agoIn the Precambrian, days lasted 19 hours The study explains Natural Earth Sciences. And it does 66 million yearsDuring the time of the dinosaurs, the The day reached 23 hours.
But experts revealed from a certain date Days add another 60 minutes.
Scientists from the Technical University of Munich (TUM) in Germany has announced that it has improved one of the instruments used to measure time.

Scientists determined that the days would lengthen over time.
With the help of this new, more accurate instrument, they were able to determine a rough date for when days on planet Earth last.
Days are 25 hours long
This tool, developed by German scientists, is called Ring Laser GyroLocated at the Wetzel Geodetic Laboratory.
This setting is important Explains the motions of the earth. Therefore, scientists were able to improve the accuracy and find that the Earth's rotation changes by 6 milliseconds every two weeks.
With the help of the gyroscope, the experts concluded that the planet Earth would begin to form Days last 25 hours in 200 million years.
The Earth's rotation speed This changes because there are dynamics that accelerate or decelerate the rotation rate in fractions of milliseconds.
