Unknown facts about gold

Sulfur plays very important role in the creation of gold deposits because it enhances gold solubility.

The US state of Nevada is the second largest concentration of gold on Earth, after the South Africa. The gold exploration in Nevada started in 1961 with the discovery of the Carlin gold mine.

Gold nanowires and nanoparticles are expected to play huge role in medicine in years to come as they can even help treat cancer because of their ability to disrupt the blood supply to cancerous tumors and they also have the potential to enable early diagnosis of several types of cancer.

Gold nanoparticles are currently also being very intensely researched for possible applications in catalysis, sensing, photonics, biolabelling, drug carriers and molecular electronics.

The record prices of gold have significantly increased the level of deforestation in certain parts of the Amazon rainforest as there is an increased number of small-scale miners blasting and clearing the forests in search for gold.

The term "fool's gold" refers to mineral pyrite because of its metallic luster.

Thew origin of gold on our planet is believed to be the result of a bombardment by meteorites which occurred more than 200 million years after Earth was formed.

There are likely no planets made entirely out of gold. This is because gold is formed together with dozens of other elements such as iron, manganese, silicon, lithium, in massive stars that become supernova. These all elements come together in a package and gold has no chemical or physical properties that would cause only gold molecules to bind together and form planets or any other space bodies.
