Things that make you go, "Hmmmmmm." Scientists have done some experimental calculating and are now concluding that the outer portion of the Earth's core is not a mixture of iron and oxygen as they had postulated, but probably contains quite a lot of silicon. They are surprised, but I'm wondering why, exactly. Haven't they ever studied the composition of lava?
