The Earth’s core just got a lot more interesting – here’s why


Even though it is hotter than anything else on or in the planet, the Earth’s inner core of iron and nickel has long thought to be entirely solid because of the intense pressure pressing in on it – but if new research is right, that isn’t entirely the case.

The Earth’s core can only be seen indirectly through data, particularly though seismic waves. When an earthquake occurs someplace in the world, the vibrations travel through the entire planet like ripples from a stone thrown in a pond.
