The terrestrial singularity causes the length of the day to change every 8.5 years

With this hypothesis, a team of researchers from the University of… Wuhan He studied how a small, hitherto unknown irregularity led to an unexpected outcome: the inner core of… Land It oscillates every 8.5 years, which explains the length of the day and night and the movement of the poles.

This would explain the failures that have occurred so far when explaining the superficial manifestations of the Earth's internal behavior.

rotation

Due to rotation, the different points of our planet lie in front of the planet respectively sunThen day arises, or they conflict and night is born. The time that elapses between two successive passes of a star at the same longitude is equivalent to the Earth's rotation, that is, the time it takes to rotate around its axis 360 degrees.

This work, based specifically on observations of this motion, confirmed that the static tilt angle means that the average density in the northwestern hemisphere of the inner core must be higher.

“Undeniably, it is difficult for seismic observations to directly detect such a static tendency of the inner core, but it is interesting that the results of seismic studies have shown that the western/northwestern hemisphere (or at least its upper layer) of the inner core has It is relatively denser.” . “These suggestions, although they have some uncertainties, are qualitatively consistent with our detection of a westward-tilted inner core, and we suggest that this consistency must be useful for differential oscillation or rotation of the inner core.”
