Is gold a space?
We all know gold is mined from the ground.
But, have you ever wondered how it got there.
Surprisingly, gold is most likely from outer space – formed in the hearts of dying stars and propelled across the galaxy by supernova explosions before crashing into primordial Earth almost 4 billion years ago..
Can gold rust?
Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Gold tarnish is usually very thin and shows up as a darkening of reflecting surfaces. …
Where is gold Most found?
