The metal which defines all interesting facts about gold
This metal many people want to own, he is accused of incitement to crime, it is considered a standard of value and measure of wealth… But many people don’t know basic things about gold, relying more on a beautiful and terrible tale.
Expensive because rare
Sometimes it seems that the gold in the world pretty much – just look at the many Windows of jewelry stores or listen to historical stories about the Inca gold! In fact it is not. This metal would not be so expensive if it is really a lot. According to statistics nowadays in an hour produces as much steel, how much humanity has developed of gold in its history. Businessman V. Buffett is confident that all the gold ever received by mankind, could form a cube with edge 20 meters. The BBC the company in turn, argues that all the world’s gold enough to pave them the courts of Wimbledon. According to the assumptions of some specialists, large gold nuggets are rare than large diamonds.
False is the idea that gold is only used for making jewelry. This is the most important technical metal with unique properties of electrical conductivity. Without gold would have been impossible, modern computer and space engineering, electrical engineering. It is used in aircraft construction and in the manufacture of windshields of automobiles (reduces sun glare). Disposal of tons of unusable computers gives the same precious metal, and 17 tons of ore.
By the way, for making jewelry, gold is not used in its pure form. Even Olympic gold medals consist mainly of silver.
If on land, a little gold, in the ocean it is much more. However, there it is quite hard to get, as it is atomized in water, and its concentration is very small. The greatest she is at considerable depths, but the man still very difficult to access. Therefore, the production of «ocean of gold» today is profitable and is not planned. But, if we could extract all the gold from ocean water, the share of each inhabitant of the Earth would have about 4 kg.
In this country there are rich gold mines, and ancient India boasts a significant production of «yellow metal». According to statistics, more than a tenth of the current international gold reserves currently owned by the Indian women. The total weight of their jewelry is estimated at 18 tons, which exceeds the total gold reserves of countries such as USA, Germany and Switzerland.
But does this mean that Indian women are very rich? Not at all. First, the population of this country exceeds one billion people, so that in recalculation per capita it turns out not so much. Second, Indian tradition considered the legal property of women clothing and jewelry. A large number of ornaments of the Indian women are trying to raise their social status. So they can often have gold rings and earrings, but do not have enough food.
Alien from the stars
Now scientists believe that the gold did not originate on Earth but came here as a result of a cosmic catastrophe after the formation of our planet. It happened over 200 million years ago. The assumption about the galactic origin of the precious metal confirmed in 2011, experts at Bristol University. Scientists drew attention to the paradox that all modern life on Earth largely depends on the metal, which fell to the planet by pure chance!
