Earth Has a Heart of Gold

Isn't that just so poetic? And new research indicates that it's true: '[Macquarie University geologist Professor Bernard Wood] says there is enough gold buried deep within the Earth's core to cover the entire land surface of the planet to a depth of half a metre... "We can say that more than 99 per cent of the Earth's gold is in the core," he said.'

Whoa.
