The Earth may record the shortest day in its history today Environment and climate

Geology and astronomical physics announced that today, Tuesday, it may record the shortest period of rotation of the Earth in modern history, to be the shortest day that the planet has recorded since the beginning of the monitoring, bypassing the record that was recorded just two weeks ago.

According to astronomical data, the shortest day of July 10, 2025, was 1.36 mm lower than the normal rate of 86 thousand and 400 seconds (24 hours), while on July 9, a decrease of 1.3 mm decreased.

The millions seem again – that is, part of a second of a second – is not perceived, but this slight change can be monitored using high -precision atomic watches that follow what is known as “LOD”, which is an accurate scientific measure of the period that the Earth takes in one full cycle.

The scientists explained that this unprecedented acceleration in the rotation of the earth may affect global positioning systems (GPS), satellites and international time standards, noting that the phenomenon is still under research, with hypotheses that link it to the changes of atmosphere, the melting of ice, and transformations in the Earth’s nucleus and the magnetic field.

Experts pointed out that the continuation of this acceleration may impose on the world a rare time step by the year 2029, which is a second quantitative addition by deleting a second from UTC (UTC) to align it with the fastest rotation of the earth.

The reason for this sudden acceleration in the rotation of the earth remains scientifically uncommon. The proposed hypotheses include the effects of the moon’s attractiveness, atmosphere changes, and the melting of polar ice.

It also includes – according to scientists – transformations in the mineral land nucleus and the weakness of the magnetic field. In this context, recent studies indicated to NASA that the possibility of entering the Earth in a state known as the “tropical balance point” with the moon, and may have given it a slight boost in its speed of rotation.

.. Andarlish of Iran study It was conducted in 2024 that the melting of the polar ice and the high level of the sea may affect the rotation of the Earth. However, instead of causing this acceleration, this redemption may reduce this severity.

As for the most likely reason, according to the study, it is the slowdown in the nucleus of the liquid earth, which may redistribute the angular momentum in a way that speeds up the scarf and dandruff a little.

According tostudy It was conducted in 2023, today was about 19 hours to a large part of the early history of the Earth, due to the balance between the tidal in the solar atmosphere, tide and lunar peripheral islands.

Over time, today it is constantly longer on Earth. The main reason was the friction of the tidal from the moon, causing it gradually away from the Earth. As it turns away, the moon drains the Earth’s energy, causing the Earth’s rotation and prolonging the days.
