Earth's Core is Superionic…

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.
