Scientists discover the Earth’s inner core isn’t solid or liquid. It’s ‘superionic.’
The structure of Earth’s core could be unlike any other state of matter, researchers have found.
Yu He, a physicist at the Chinese Academy of Sciences and lead author of a study published this month in the journal Nature, said the calculations challenged what researchers once understood about the inner core.
He and his colleagues found the inner core creates a “superionic state” made up of hydrogen, oxygen and carbon. He said it’s unlike any solid or liquid form.
