A seismic discovery has shaken Australia’s most basic understanding of the Earth by revealing that its centre is not a gooey mass, but a solid metallic ball.
Discovery reveals hard metallic truth at Earth’s centre
Australian scientists have made a ground-breaking discovery deep below the Earth’s surface.
Their research confirms a 20-year-old hypothesis by revealing the planet, much like a Kinder Surprise, has an hard, inedible mass at its centre.
Beneath the planet’s well-known crunchy crust, molten mantle, and creamy outer and inner core, scientists found a surprise fifth layer comprised of a solid metallic ball.
Australian National University researcher Professor Hrvoje Tkalčić says the discovery reveals a lot about the planet’s evolution.
