The miracle at the center of the Earth, every 8 and a half years the inner core

Scientists in China have recently made a discovery about the heart of our planet. Every eight and a half years, the Earth's inner core wobbles around its axis of rotation.

This change is likely caused by a slight mismatch between the inner core and the Earth's mantle, the layer below the Earth's crust, according to a new scientific study.

Starting about 2,896 kilometers below the surface, the Earth's core is divided into a rotating liquid outer boundary and a mostly solid inner layer. This area is partly responsible for many of our planet's geophysical dynamics, from the length of each day to the Earth's magnetic field, which helps protect humanity from harmful rays emitted by the Sun.

For their latest study, Hoao Ding and his co-authors further confirmed this cycle by measuring small shifts in day length around the world, which control the periodic movement of Earth's spin axis, and comparing them to variations in the previously identified polar movement.

Their data suggest that this wobble is likely caused by a tilt of 0.17 degrees between the Earth's inner core and mantle, which contradicts the traditional theory of Earth's rotation, which assumes that the axis of rotation of the Earth's core interior of the Earth and the axis of rotation of the mantle coincide.

This tilt, according to the research, could mean that the northwestern hemisphere of the inner core may be slightly denser than the rest of this layer, and that there is a difference in density between Earth's inner and outer core.

In the future, this discovery could help researchers understand the dynamics between Earth's inner core and processes that affect humanity, from earthquakes to changes in the magnetic field.

This newly discovered tilt in the inner core could eventually lead to a change in the shape and motion of the liquid core, leading to a possible shift in Earth's magnetic field.
