The earth was born 4.6 billion years ago. The early earth did not have such a beautiful and perfect ecosystem as it is now, but a purgatory planet. So how did the earth gradually develop a beautiful ecosystem and give birth to life?
Speaking of the earth from its birth to its evolution into a living planet, there is so much luck in it. We must know that the solar system is habitable with three terrestrial planets, and only the earth is a beautiful planet of life, the other two are a purgatory world and the other is a desert world.
The earth can have such a beautiful ecological environment, water is an important element, followed by abundant various heavy elements. Water is the source of life. Without water, life can hardly be born, and if the various elements needed for life do not exist, then life cannot evolve even if there is water, let alone evolve into intelligent life.
So how did the earth’s water and various heavy elements come from? In this regard, after continuous research and exploration, scientists have put forward a more reliable conjecture, which is caused by the impact of asteroids and comets. We must know that the early solar system was very unstable. At that time, celestial collision events often occurred.
After the birth of the earth, the frequency of collisions by various asteroids was also very high, and in the course of a large number of collisions, comets brought water and life to the earth. The various asteroids and other celestial bodies have brought some rich heavy elements to the earth, such as gold.
I believe that everyone is very familiar with and likes gold, and the price of gold is naturally expensive, which is why it has a very high value. In addition to many industries that need gold, the most important thing is its rarity. The gold mines that we can mine are actually relatively small, and the reserves are also very limited.
Many people may say that the earth’s gold reserves are already very scarce, and it makes sense that it is expensive. So are the earth’s gold reserves really very scarce? This may not be the case. Let’s look at a famous crater. Although the Earth is a living planet, it has suffered a lot of asteroid impacts over the course of billions of years.
There are currently ten major craters on the earth. Some of them were formed tens of millions of years ago, while others were formed billions of years. Take the Yucatan crater, for example, which has a diameter of more than 198 kilometers and was formed 65 million years ago. This time coincides with the extinction time of the dinosaurs, so many scientists speculate that it may have been formed after the huge asteroid that caused the extinction of the dinosaurs hit the earth.
The Yucatan crater is not the largest crater on earth. The largest crater is Friedberg Crater, which has a diameter of more than 380 kilometers and was formed 2.033 billion years ago. It can be said to be the oldest, largest and most eroded crater in the history of the earth.
If it weren’t for observations from high altitudes, it would be difficult for us to imagine that this place with a large population of people turned out to be a huge crater. For this crater, scientists are naturally very concerned about its research, because it was formed more than 20 years ago. Through it, we can understand the evolution of the early Earth.
During continuous research and exploration, scientists discovered that the bottom of Friedberg Crater is a huge treasure, and there may be at least 1,000 tons of gold reserves inside. So much gold naturally makes many people very excited and want to mine it out. However, until now, no one has been seen to mine the gold at the bottom of Friedberg Crater. Why?
Why don’t we mine the gold here? Know that more than 1,000 tons of gold is a huge amount of wealth. There are two main reasons why humans did not mine the gold in this crater. One reason is that the emergence of these large amounts of gold will make the gold market turbulent and unstable, which will affect the stability of the global financial market.
The second reason is to protect this huge crater, which is a unique crater on earth. Its age is as long as 2 billion years ago, and it has gone through a long 2 billion years. In such a long time, the crater can effectively preserve some historical traces due to its special environment.
Scientists hope to explore this ancient crater through research and reveal some of the mysteries of the earth 2 billion years ago and 2 billion years ago. The significance of this kind of research is far more than that we should destroy the crater to mine gold, which is not worth the loss. Therefore, this crater has been rated as one of the World Heritage Sites, and private mining and sale by any country is prohibited.
It seems that many people’s dreams of getting rich in gold have been shattered, so apart from the thousands of tons of gold inside this crater, is the earth’s gold reserves not rich? Of course not. In fact, the earth’s gold reserves are far beyond our imagination. During the process of studying the earth’s history, scientists discovered that the early earth might have had a golden rain.
This golden rain came from outside the solar system. After entering the solar system, a large number of celestial fragments carrying gold fell on the earth, forming a spectacular golden meteor shower. Since the earth had just been born at that time, it was still in a molten state. After these gold fragments entered the earth, they were continuously deposited into the interior of the earth through geological movement.
Scientists speculate that the amount of gold that has landed on the earth may have reached 6 billion tons. I believe everyone will feel incredible after seeing this amount of gold. If all of them appear on the market, the price of gold may not even be as good as iron. Unfortunately, although we know that the earth once had a vast golden rain, there were 6 billion tons of gold on the earth, but we are unable to deal with them now. Mining.
The reason is that they are in the inner part of the earth, and they are also very deep. I believe many friends are aware of the Kola ultra-deep borehole. This was a magnificent underground drilling scientific research experiment conducted by Soviet scientists during the last World-U.S.-Soviet competition. The Kola ultra-deep drilling experiment has been conducted for more than 20 years, and the deepest point reached 12,262 meters.
In this ultra-deep drilling experiment, scientists obtained some precious underground rock data at different depths. For example, at a position of about 7000 meters, a gold layer was discovered. This location may be an area formed by gold deposits after the early golden rain fell on the earth.
If 6 billion tons of gold are concentrated at the position of 7000 meters, then we need very strong scientific and technological strength to mine. With the current technology of mankind, I can only hope Jin Xing sigh. Of course, science and technology are constantly advancing. In the future, we will inevitably continue to explore the mysteries of the earth’s interior. One day, we will be able to easily enter the earth’s interior and mine resources deep underground.
As many as 6 billion tons of gold will one day come into existence, so at that time, will gold depreciate to be very cheap? The possibility is very small. You must know that gold is a very important industrial raw material, and many technological products require the addition of gold. With the rapid development of human technology, the demand for gold in the future will also increase.
Although the gold reserves inside the earth are very rich, they may not be able to meet the development needs of mankind. The conditions for the formation of gold, a precious metal element, are very harsh. Studies have found that gold may only be formed during a supernova explosion. If this is the case, then gold may also be a relatively scarce element in the universe.
From this we can also see that the earth is really lucky. Not only is it very fortunate to become a planet of life and give birth to intelligent human beings, but also during the early evolution of the earth, it is also very fortunate to attract many resource celestial bodies. The impact has formed a wealth of various resources, which are stored inside the earth, waiting for human exploitation and application.
