1. There’s gold inside your body:
You read that correctly – the average human body contains about 0.2 milligrams of gold, mostly in the blood. It doesn’t serve a known biological purpose; it’s just there.
2. The world’s oceans are awash in gold:
Earth’s oceans contain an estimated 20 million tons of dissolved gold, but it’s so dilute (about 13 parts per trillion) that extracting it would cost far more than the gold is worth.
3. Gold can be stretched unbelievably thin:
A single ounce of gold can be hammered into a sheet nearly 100 square feet or drawn into a wire 50 miles long. It’s one of the most malleable and ductile materials known to exist.
4. Exploding stars likely created the Earth’s gold:
Most gold on Earth is believed to have originated from supernovae or neutron star collisions that occurred long before our solar system was formed.
5. There’s a golden asteroid worth a quadrillion:
The asteroid 16 Psyche contains massive amounts of iron, nickel, and traces of precious metals, possibly including gold. Some early estimates pegged its value to the quadrillions, earning it the nickname “the golden asteroid.”
