Gold is one of the most electrical conductive elements in the world. However, gold doesn’t come from this world. Gold is the byproduct of supernovas, or when a star collapses on itself and explodes. The large amounts of energy allow heavy elements to be created such as gold. It is created in a second and then distributed out into space.  Uranium can also be created. This explains why gold is so expensive, and is not found in large quantities at once.
