Scientists have made a groundbreaking discovery about the inner core of our planet, shedding light on its long-mysterious behavior. A team of researchers has found evidence that the inner core is changing shape as it rotates, creating hills and valleys along its border. This deformation could be causing some areas to accumulate more material while others lose it. The study’s findings provide a significant update to our understanding of Earth’s internal dynamics and raise questions about the long-term impact on our planet’s structure.
