TED-Ed: Where does gold come from? - David Lunney

The video explores the historical quest of alchemists to turn lead into gold, a dream now achievable through modern technology. Gold's origin is traced back to supernovae, where heavy elements are formed. The process of nuclear fusion in stars and the subsequent formation of elements like gold during supernovae is explained. Gold's journey to Earth and its rarity are discussed, highlighting the challenges of mining. The video also covers the potential of producing gold using particle accelerators, though it's not cost-effective. Future sources of gold, such as oceans and space, are considered, with a nod to the possibility of future supernovae delivering more gold.

What are the challenges associated with extracting gold from the ocean?
