As of my understanding, there is no scientific consensus or widely accepted theory suggesting that the core of the Earth will change its direction of rotation.
The Earth's core consists of two main parts: the inner core, which is solid and primarily composed of iron, and the outer core, which is in a liquid state. The outer core is responsible for generating the Earth's magnetic field through a process called the geodynamo.
While the Earth's magnetic field is known to undergo changes over long geological timescales, including reversals of the magnetic poles, there is no scientific evidence or significant research suggesting that the rotation direction of the Earth's core will change.
It's important to note that the dynamics and behavior of the Earth's core are complex and not fully understood. Scientists continue to study the Earth's interior using various methods, including seismology, geodesy, and geomagnetism, to better understand its structure and processes. Any significant changes or new discoveries regarding the rotation direction of the Earth's core would require further scientific investigation and evidence.
