There is a liquid core and a viscous mantle inside, but the very center is considered to be solidified. But there are also inhomogeneities in it, and most importantly, its behavior is alarming. The fact is that the rotation speed of the inner core changes over a period of a few years. This was established by recording seismic waves from repeated earthquakes. In recent years, the rotation of the inner core has accelerated and slowed down compared to the rotation of the rest of the planet's mass. In the new work, scientists reanalyzed the data obtained over the past 20 years and discovered an anomaly near the boundary of the two parts of the core.
