This revelation was made possible by the creation of the most intricate map of the geology beneath the southern hemisphere of our planet. If validated, this concept of a "recycled" ocean floor could function like a thermal blanket, trapping heat within the core. Samantha Hansen, the lead author of the study and a professor of geological sciences at the University of Alabama, explained in an email to Insider.
