A proposito di questo titolo

Gold is a remarkable noble metal defined by its extraordinary malleability and extreme chemical stability. As the most malleable of all known metals, a single ounce, roughly the size of a large marble, can be hammered into a translucent sheet of gold leaf covering 100 square feet or drawn into a wire significantly thinner than a human hair. Because gold does not oxidize or corrode when exposed to moisture or biological systems, it is considered biologically inert and technically edible. This unique stability makes gold essential in modern medicine for dental crowns and specialized treatments for rheumatoid arthritis, as well as in aerospace engineering, where microscopic layers on astronaut helmet visors reflect intense solar infrared radiation. The presence of gold on Earth is the result of violent cosmic phenomena, specifically the supernova explosions of dying stars or the high-energy collisions of neutron stars. While much of Earth's native gold sank into its molten core during the planet's formation, the gold accessible in the crust today was likely delivered by a massive meteor bombardment approximately four billion years ago. Despite its prominence in global culture, gold remains exceptionally scarce. The total volume mined throughout human history, approximately 200,000 metric tons, would fit into just over three Olympic-sized swimming pools. This scarcity, combined with unusual natural occurrences like eucalyptus trees absorbing gold particles through their roots, continues to solidify gold's status as one of the world's most valued substances.
