Earth’s hidden cache of gold
According to Australian geologist Bernard Wood, 99 percent of the earth’s gold is missing. A cache of 1.6 quadrillion tons of gold and 6 times more platinum were pulled to the center of the earth billions of years ago when the planet was still a ball of molten magma.
“…there's enough gold in Earth's core to coat its surface in 1.5 feet of the stuff."
