💰 Day 30: A Planet Paved in Gold
Did you know that there is enough gold in the Earth's core to cover the entire surface of the planet in a layer 1.5 feet (45 cm) thick?
While gold is rare and expensive on the surface, our planet is actually packed with it—it’s just tucked away where we can’t reach it.
More Details: Our Treasure-Filled Core
The Sinking of Riches: When Earth was still a molten ball of fire 4.5 billion years ago, heavy metals like iron and nickel sank to the center to form the core. Because gold is "siderophilic" (iron-loving), it hitched a ride, leaving the crust relatively gold-poor.
The 99% Rule: Scientists estimate that 99% of all the gold on Earth is located in the core. If we could somehow extract it all, there would be enough to give every person on the planet several tons of the precious metal.
Meteorite Delivery: Almost all the gold we have ever mined—from wedding rings to gold bars—didn't come from the core. It actually arrived later via a "Late Heavy Bombardment" of meteorites that slammed into the Earth's crust after the core had already formed.
A Solid Treasure: To get to this gold, you’d have to travel 1,800 miles (3,000 km) down to a place as hot as the surface of the sun (5,400°C), where the pressure is millions of times higher than at sea level.
We are literally walking on a massive treasure chest floating through the cosmos.
