Let's unlock the most interesting secrets of gold and learn 15 amazing facts about this precious metal.
Do you know that:
1. The origin of gold is still a mystery. Some scientists believe that the precious metal was formed as a result of chemical processes on Earth. In recent years, the theory prevails that gold was brought from space. According to one version, gold originated deep within the ancient stars that exploded and later scattered it throughout the universe.
2. The largest quantity of molten gold is concentrated in the Earth’s core. If the planet was covered in metal, its layer would be 1,5 meters thick.
3. In the entire history of mankind, nearly 200000 tons of gold have been mined. A giant cube cast from such a quantity of metal would reach the height of a six-story building. Having melted all this gold, we would be able to fill three fifty-meter-long Olympic pools.
4. The biggest gold nugget was found in Australia in 1872. With a total weight of 235,5 kilograms, the specimen contained 83,2 kilograms of gold. The discovered object was called the “Holtermann Nugget”.
