Earth turns faster faster science:
The time. Meanwhile, which many of us believe immutable, is in fact a phenomenon in perpetual evolution. For example, For decades, high precision means of measurement have revealed that the land has gradually accelerated. Meanwhile, Although it is an imperceptible phenomenon on a daily basis, it is of capital importance. Furthermore, Studying it helps better Understand the behavior of our planet While raising many questions about forces that have an. Nevertheless, impact on his rotation. Similarly, It turns out that this slowdown is the fruit of the gravitational influence of the moon. However, in recent years, this trend seems to be reverse. However, The blue planet turns faster.
Pronounced acceleration – Earth turns faster faster science
Since the beginning of 2025. Therefore, researchers have observed three days including The duration was slightly less than the usual 24 hours : July 9, July 22, and more recently, August 5. The earth turns faster faster science latter was distinguished by a remarkable reduction of 1.51 millisecond compared to the standard duration of 86,400 seconds. However, she did not break the record of July 5, 2024 during which the day was 1.66 millisecond shorter. You should know that to measure these variations. scientists use atomic clocks, the accuracy of which makes it possible to assess the fluctuations from earthly rotation to the millisecond.
A dynamic still misunderstood
Although the exact causes of these temporary accelerations remain unclear. it would seem that, once again, the moon has something to do with it. When he is at his point furthest from the terrestrial equator, The star produces an asymmetrical gravitational attraction. This configuration would have a slight impact on the oscillation of the axis of the earth. which would have the effect of generating a slight increase in the speed of rotation. Anyway, it is only a simple hypothesis. Some astronomers believe that this phenomenon could be due to internal factors such as the movements of the terrestrial nucleus. earthquakes or mass redistributions due to the melting of glaciers.
Soon a second less?
Others advance possible external influences, in particular possible gravitational interactions with distant celestial bodies. For the time being, earth turns faster faster science there is therefore no theory to fully explain this dynamic. But if this acceleration continues, it could force us to review our way of measuring time. It is for this reason that since the beginning of the 1970, scientists have been correcting atomic clocks with “intercalaire seconds”. These adjustments allow Compensate for the variations in the rotation of our planet. So far, interventions consisted of adding time. But if the earth continues its acceleration, it could soon have to withdraw a second! Did you know that the rotation of the earth was so scrutinized?
