In February 2025, a group of geophysicists published a study that suggests changes are underway in the Earth's inner core. Already in 2023, we learned that the rotational direction of our planet's inner core may have changed, or even reversed, in around 2009. The new study suggests, however, that it is not only the rotation of the Earth's center that is subject to change. Indeed, the shape of the Earth's innermost layer may not be fixed, either.
