Core Insights - The article discusses the origins of gold on Earth, suggesting that it primarily comes from meteorites that impacted the planet during its early formation [1][3] - It highlights the significance of gold as a measure of a country's strength, despite the shift to fiat currencies [1] Group 1: Origin of Gold - Approximately 4.5 billion years ago, gold was present on Earth's surface due to meteorite impacts, but most of it sank into the core as iron did [3] - The current concentration of gold in the Earth's crust is about 1.3 grams per 1,000 tons of material, which is higher than previously estimated [3] - The prevailing theory, known as the late veneer hypothesis, posits that a significant meteorite bombardment brought gold to the mantle and crust after the core formed [3] Group 2: Scientific Theories - The late veneer hypothesis is now a fundamental theory in planetary science, explaining various geological anomalies and the origins of other essential elements for life [3] - Elements such as carbon, nitrogen, water, and amino acids may also have extraterrestrial origins, similar to gold [3]
