If today’s day (Wednesday, July 9, 2025) seem smaller than a 24 -hour ordinary, you will be right, as there is a scientific phenomenon responsible for it.
The land, according to scientists, is expected to speed up its rotation in the coming weeks, making a few days shorter. Today will be from 1.3 to 1.6 mm a second than the standard 24 hours, making it one of the smallest days in history.
What is causing the phenomenon
This phenomenon occurs because the Moon has moved closer to the poles, causing the Earth to rotate faster this month, experts explain.
One day on Earth is the amount of time our planet takes to completely rotate around its axis. That is, 86,400 seconds or 24 hours. However, rotation of the Earth is influenced by various factors, such as the position of the Sun and the Moon, the changes in the magnetic field of the planet and the balance of mass on it, Livescience reports.
In 2020, scientists found that the Earth has begun to rotate faster than any other time. And since they began to recording its rotation in the 1970s. On July 5, 2024, we had the shorter day ever recorded, which was 1.66mm of a second less than 24 hours. About the same levels will move today.
And other shorter days
According to the International Earth Rotation and Report Systems (IERs), 22 is expected to be brieflyor July and 5or August. The organization is responsible for managing the “negative vaccine second” that will result from this series of short days, which will lead to the first kind of regulation of the world watch.
This special change is projected to take place in 2029 and will result in the first adjustment of this species.
“It will be an unprecedented situation and a big deal,” said Duncan Agnew, a geophysicist at the Scripps Institute of Oceanography at the University of California in San Diego. “This is not a huge change in the rotation of the Earth that will lead to a disaster or something, but it is noteworthy,” he added.
We may believe that a few milliseconds do not matter, but in the world of technology and telecommunications, every fraction of a second counts.
Scientists even believe that if this trend continues, in about 50 billion years the rotation of the Earth will synchronize with the moon orbit. In this case, there would be no tides and we would always see the same side of the Moon, which would only be visible on the half planet.
