Is gold sustainable

Answer 1

I am not sure I understand exactly what you are asking. If you are asking if gold will not derteriorate over time the answer is it will not. Gold sustains itself extremely well. That is why it has lasted so well since ancient times in Egypt. If you are wondering whether there is an unlimited amount of gold in the world, there is not. Furthermore, there is no new gold being produced on Earth. What we have is all we will ever have unless a chunk of gold from space lands here. Gold is an element and like all elements, except hydrogen, gold is mde in stellar processes during nuclear fusion. Gold is one of the hevier elements, #79 to be exact, so it is most likely made during Supernova explosions in super-massive stars when smaller atoms fuse together to make bigger atoms. It will then drift around space for a while, perhaps a billion years or so, and then collect and mix with other stuff like rocky material and metals in a solar system protodisk. So, all of the gold on Earth has been here since the planet formed and once we have found it all there will be no more to find. Obviously gold is pretty rare or it wouldn't be worth so much. Aluminum is cheaper because there is more of it here and it's easier to find and process. On the other hand, platinum is more rare than gold and therefore more valuble. All three are non-renewable and what is on Earth is all that is on Earth.
