Why won't gold depreciate???

You know gold is a non renewable resource on earth , It comes from meteorites in outer space , Around the 40 The extremely dense elements produced by the explosion of a neutron star billion years ago , Among them is gold , After the formation of gold, it will be thrown into the universe along with other elements to avoid the surface of the star with the explosion of the star , And mixed with the original interstellar matter in the universe , In the process , It's hard for gold to come together to form a new planet , Some of the gold collided with the earth , Because the density of gold is greater than that of other elements on the earth , Therefore, in the long temperament movement, the gold element gradually settles towards the geocenter , This has led to 99% All the gold has entered the earth's core . In the universe, a neutron star explodes . Does not see more , And not all elements will become gold , Only 1% The elements of will become high-density elements , this 1% And only a small part of it will form gold , So gold is very rare in the whole universe , In ancient times, gold was used as currency , There is no practical use , But with the progress of human technology , There is a growing need for gold in the electronic components of precision automation instruments , Because gold has a high melting point, strong corrosion resistance and good conductivity , It is widely used in the aerospace field , In the era of aerospace and science and technology , Less gold is used , So buying gold will never reduce prices
