Earth's core derailed, one day is not 24 hours

Research just published in Science Advances shows that Earth's inner core even "displaced gears", spinning in the same direction as the rest for about six years between 1969 and 1971, according to an analysis of geospatial data. concussion. In the period 1971-1974, it continued to change direction.

The length of the day also increases and then shrinks during these two periods without human knowledge.

The layers of the Earth are not aligned and move in the same direction as imagined, but the core always has its own speed and direction of rotation.

The initial evidence was obtained by accident. The team led by Earth Science professor John E. Vidale from the University of Southern California's School of Letters, Arts and Sciences used measurement data from the Large Aperture Seismometric Array (LASA) of the University of Southern California. The US Air Force, based in Montana, to demonstrate that the Earth's inner core is rotating faster than the rest of the Earth, although not as fast as previously believed.

The new beam-forming techniques that Professor Vidale developed also help find new evidence of the core's rotational speed through an old set of data - waves generated by underground nuclear bomb tests by Earth. Soviet Union 1971-1974 - and discovered rotational direction reversal of at least 1/10 of a degree per year.

According to PHYS, this is the first time that the controversial theory of the "displacement" rotation of the Earth's core has been practically proven.

This results in a cycle of 6 years, where a day varies from about 0.2 seconds shorter than 24 hours to about 0.2 seconds longer than 24 hours, something we hardly notice.
