Earths inner core may be deforming within years scientists say its hidden movements could change the length of our days

Earth's rotation experiences slight variations in day length due to interactions within its inner core and mantle. Researchers have developed a model revealing how gravitational forces drive these changes over decades. The inner core is not completely rigid and can undergo deformation within years. Electromagnetic and mechanical forces at the core-mantle boundary oppose gravitational torque. These findings provide insights into Earth's internal processes and structure.
