For human beings, gold is a symbol of wealth, precisely because gold is very rare, so the price of gold is also very expensive. But what many people don't know is that there is far more gold on the earth than we think, according to expert calculations, there are about 400 million tons of gold on the earth, and if you take a look at it per capita, each person can get more than 500 tons.
Where is this gold hidden? Recently, China's Henan has excavated a gold mine with an estimated reserve of 31.55 tons, which can be regarded as a very large gold mine. Is there really so much gold on Earth?
<h1 class="pgc-h-arrow-right" data-track="3" > where did gold come from? </h1>
Gold is actually essentially a gold element, its atomic number is 79, which is a relatively high ordinal element, and the higher the ordinal element is more difficult to form in the universe.
The periodic table, from hydrogen to iron, is produced by nuclear fusion in the stellar core, and each time the nuclei merge into a larger nucleus, the number of protons increases, the number of atomic numbers increases, and new elements are formed.
For a star, even if its mass is large enough, it can only generate iron atoms at most, and the elements after that are difficult to continue. So how are the elements after the iron element generated?
The answer is supernova explosions and neutron star mergers. The super energy generated by the supernova explosion can produce elements larger than the atomic number of iron, while the merger of neutron stars will produce strong gravitational waves, resulting in elements such as gold and silver. Most of the gold element is produced by the merger of neutron stars.
<h1 class="pgc-h-arrow-right" data-track="8" where is the gold on Earth >? </h1>
Since gold appeared in the explosion of supernovae and the merger of neutron stars, this means that gold actually existed before the formation of the Earth.
At the beginning of the formation of the Earth, the entire planet was still in a state of melting, when the surrounding celestial bodies produced neutron star mergers or supernova explosions, gold elements were sprayed in the universe, and some of the elements reached The Earth. In the molten state, dense substances sink preferentially, gold is 2.4 times denser than iron, so gold is more likely to settle into the core, while other lighter elements are more likely to appear in our crust. So these gold elements participated in the formation of the earth, and fused into the core of the earth.
Everyone knows that all the gold we can dig is above the earth's crust, and in fact most of the earth's gold is buried in the core of the earth. Scientific research has shown that if we extract all the gold in the core of the earth and lay it flat on the surface of the earth, we will get a layer of pure gold crust at a height of 4 meters, which shows how rich the gold in the core of the earth is. Much of the gold in our crust is also shaken to the crust by geological activity from the core.
But according to the current technology of mankind, it is impossible to dig into the core of the earth to extract gold. Scientists calculate that there will be about 60 trillion tons of gold on the earth's crust, and as human technology develops, more and more gold mines will be discovered and excavated.
The abundance of gold on the Earth's crust is very low, especially compared to the core. Although the whole earth has very rich gold reserves, gold is indeed a relatively rare metal from the perspective of the formation process, which is why people will be human gold and precious reasons.
<h1 class="pgc-h-arrow-right" data-track="14" > will the price of gold be lowered > mining gold? </h1>
Everyone knows that from the perspective of commodities, the supply and demand of the market determines the price, and if the market supply of a product is large, then it is likely to reduce the price. For gold, does such a market law still exist?
In fact, the exploitation of large gold mines has almost no impact on gold prices, first of all, from the discovery of gold to the final extraction of gold is a long time, secondly, gold in the process of human history has been given strategic significance at the national level, we found that the number of gold mines is difficult to affect the price of gold, but the pattern of international relations changes, the price of oil, etc. will affect the price of gold.
However, although the earth has so much gold, there is still no 1g that belongs to me. In the end, it was left with tears of poverty.
