Earth usually takes 86400 seconds, 24 hours a day. But the speed of its rotation depends on several factors, such as the position of the moon, the gravitational field and even changes in the nucleus of the planet.
When the impact of gravity focuses on the poles more than Ecuador, the Earth's mass is redistributed from the rotation axis, which speeds up the planet's rotation rate Eder Molina, Geophysics, to USP
A phenomenon has been observed since 2020. “We have a little shorter days than in the past fifty years,” said Derk Pester, Germany's National Meteorological Institute for Living Sciences. The effect may seem minimal, but it is related to systems that require flour synchronization, such as GPS, banks, electrical networks and satellites.
We transfer data at a very high speed. Everything needs to have time for computers to see what is happening David Gosard, physicist, to the guardian
Since 1972, the atomic watches have been adjusted in seconds to align the official time (UTC) with the Earth's rotation. But with the last acceleration, some scholars look at an unprecedented procedure: to remove a second, and create a “second negative leap”.
