The Sun is an appropriate venue for baffling news: On February 24, the paper reported that scientists are puzzled by the discovery of new substances at the Earth’s core.
Rather than solid or liquid, as scientists have long believed, Earth’s core exists in a “superionic state” – or something that’s a bit of both. Scientists believe that hydrogen, oxygen and carbon molecules swirl around a lattice of iron. “The solidification of iron at the inner core boundary does not change the mobility of these light elements, and the convection of light elements is continuous in the inner core,” said Professor He Yu, who lead the research said.
What’s down there? What could it mean? What happens next?
