A day on Earth is about to have 25 hours
According to scientists' calculations, the Moon is gradually moving away from Earth, making a day on the blue planet longer and a 25th hour is expected to appear.

| Earth will have 25th hour because the Moon is gradually moving away. |
In a new study conducted by the US National Academy of Sciences, scientists have demonstrated how the Moon affects the day on Earth.
Specifically, 1.4 billion years ago, the Moon was very close to Earth and a day at that time only lasted about 18 hours. Until now, a day has 24 hours and the Moon is still gradually moving away from the blue planet at a speed of 3.82 cm/year.
According to calculations by Geography Professor Stephen Meyers of the University of Wisconsin-Madison, if the Moon continues to move away from Earth at this rate, time will lengthen by 2 milliseconds per century. This means that in about 200 million years, a 25th hour will appear, assuming the time scales are the same as they are today.
Besides, Professor Meyers also affirmed that if at that time, humans still existed, they would certainly have to re-divide time zones to suit the outside circumstances./.
