What is hidden in the underground world? The former Soviet Union once dug into the "Gate of Hell"

The farthest place that human beings have been in the universe is the moon, which is 380 thousand kilometers away from us; The deepest point in the sea is 1. 1 10,000 meters; Relatively speaking, we know very little about the land under our feet.

At present, the deepest excavation depth of mankind is less than 0.2% of that of radius of the earth, which makes people curious. What secrets are hidden in the unknown underground world? Let's dig down together

First of all, we dig 3 meters underground, which is the general burial depth, because burying the body at this depth can effectively avoid the spread of the plague.

Continue to dig 4 meters underground, which is the depth of the deepest ant nest in the world and the grave depth of the young Egyptian Pharaoh Tutankhamun.

At that time, there were rumors that it was a cursed tomb, because Lord carnarvon, the first person to enter the tomb, died of mosquito bites a year later.

6 meters underground, which is the deepest depth that metal detectors can detect.

Underground 12 meter is the deepest cave depth found by animals at present, which comes from the hands of Nile crocodiles.

It is 20 meters underground, which is the depth of the catacombs in Paris. Insufficient cemetery area is an inevitable trend of burial. /kloc-in the 0 th and 8 th centuries, a large-scale smallpox broke out in Paris, and a large number of residents died, which directly led to the dead people having no place to be buried.

There is no way, the government can only order the previous bodies to be dug up and transferred to an abandoned mine. This is a very hard job, and the priests are responsible for it.

18 10 was finally officially completed, and 6 million bodies were piled together. But so many bones simply don't match, and finally the priests can only classify and pile them up.

There are walls piled with bones everywhere, which makes people forget that these people used to be real people, as if these bones were just building materials. About 500,000 tourists come here for sightseeing every year.

It is 35 meters underground, which is the depth of the top floor of the Qin Shihuang Mausoleum, but we don't know how deep it is because the Qin Shihuang Mausoleum has not been excavated.

However, according to historical records, Li Si, the prime minister in charge of tomb design at that time, described that it was impossible to dig, and he thought it should be dug to the bottom of the underground.

The construction of the Mausoleum of the First Qin Emperor involved 800,000 laborers, covering an area of 56.25 square kilometers. It was built continuously for 39 years, and it was not completed until two years after the death of Qin Shihuang.

Foreign experts believe that the depth of the Qin Shihuang Mausoleum is between 500m and1500m.

According to records, there are countless treasures in the mausoleum of the First Qin Emperor, and in order not to spread the secrets in the mausoleum, after the restoration of the mausoleum, hundreds of thousands of craftsmen were sealed in the mausoleum, and no one was spared.

It is 85 meters underground, which is the depth of the underground city of Capadocia, equivalent to the height of the twenty or thirty floors of the building.

It is said that this underground city was established by Christians at that time to avoid the persecution of the Romans, and it has a kitchen, a toilet and an animal breeding base.

But we don't know the real use, because this underground city can live 6.5438+0.5 million people. If it is only a refuge for Christians, it is obviously overqualified.

Underground105m, it is the deepest subway station in the world. The depth of Arsenal Station is located in Kiev, Ukraine. Because the geology is not hard enough, I have been digging to this depth.

Underground 155 meters, which is the depth of the deepest hotel at present. This hotel is in Sweden. It's called Sarah Silver Mine Hotel.

There is a reason to call the Silver Mine Hotel, because this hotel is converted from a hollowed-out silver mine, where you can stay and explore. It is said that the lowest price in this hotel is 4000 yuan per night.

700 meters underground is the depth of Chile's mine disaster in 20 10, which is called 2 1 century miracle.

20 10 on August 5, the San Jose copper mine in Chile collapsed, trapping 33 miners 700 meters underground. Rescuers don't know their location, so they can only look for them blindly.

At first, they dug a small hole for two weeks. Finally, they heard the sound of knocking 688 meters underground, so they continued to dig according to the sound.

After a few days, I finally saw that all the people below survived. They are crowded in a very small place. Because the hole is too small, they can only write a note and bring it back to the ground through the drill.

The note says that all 33 of us are still alive, but we are running out of water and food. Fortunately, they happened to be trapped in the food storage.

So rescuers began to dig a big hole to rescue them, which was quite difficult. It took two months and 69 days to dig through. All 33 people survived. This is the most classic super rescue in history, and it is a miracle.

Underground 22 12 meters, it is the deepest natural cave in the world at present. The name of this cave is "Veryovkin a", and this is only the known depth at present, and it may continue to deepen with human exploration.

It is 2400 meters underground, which is the depth of the deepest laboratory in the world. This is the Jinping Deep Underground Dark Matter Laboratory in Sichuan, China.

Dark matter is a substance that can penetrate anything, but it has not been observed yet. The laboratory is deep and can shield all cosmic rays. If the detector still reacts at this depth, it proves that dark matter has been found.

This laboratory means that China has started the most advanced research in the world. Once dark matter is confirmed, it will set off a great revolution in the fields of astronomy and physics in the world.

It is 3600 meters underground, which is the deepest depth that multicellular organisms can survive at present. This creature is called devil bug. According to research, this kind of creature can survive under extreme conditions and fully adapt to the environment of high pressure and high temperature.

Scientists say that with such tenacious vitality, we can send it to Mars first to explore the road for us.

It is 3902 meters underground, which is the deepest depth that human beings have reached so far. It is the most famous gold mine in South Africa-Taotona Gold Mine. There are 35,000 people working in this 3-kilometer-deep mine.

Underground 12263 meters, which is the deepest hole ever dug by human beings. During the cold war between the United States and the Soviet Union, Soviet scientists planned to dig a hole all the way to the other side of the earth.

The hole was dug for nearly 20 years, but at this depth, the plan was stopped by the government. The official reason is insufficient funds.

However, Dr. Dimir Asagov, a famous geologist in the former Soviet Union who participated in the project, said that when the drill bit reached the depth of 12263 km underground, the drill bit suddenly rotated at a high speed, which indicated that there was a hole below.

Not only that, they also received a recording, which is called the sound of hell, just like the screams when people are tortured. So they decided not to dig any more and sealed the well.

"As an atheist party member, I didn't believe in heaven or hell, but as a scientist, I can't help but believe in hell now." Dr. Asagov said.

These are just rumors. The real reason for the plan to stop may be that the lower the temperature is, the higher the temperature is, and the bit melts at a depth of12000m, so the plan has to be stopped.

Speaking of the former Soviet Union, we have to make another hole in front of the Soviet Union, which can be said to have really opened the "gate of hell".

197 1 geologists of the former Soviet Union accidentally discovered a cave full of natural gas while drilling in Turkmenistan. In order to prevent natural gas leakage from affecting the lives of local residents, they had to ignite natural gas.

Originally, they planned to continue the downward exploration after the natural gas burned out, but unexpectedly, the fire has been burning for almost fifty years and has not been extinguished until today.

These wasted natural gas are said to be worth as much as 5 billion yuan.

From 33,000 meters to 800,000 meters underground, this layer is called the upper mantle, where the dark underground world is illuminated, and the extremely high pressure and temperature underground make all the stones here glow.

And this layer of stone is not an ordinary stone, but a gem. These gems are mainly olivine, as well as rubies and diamonds.

How did you know? Because volcanic eruption can often bring out things in the upper mantle, and various gems are often found in solidified magma, it is speculated that gems may be the most abundant substance on earth.

800,000 to 2.8 million meters underground, this layer is called the lower mantle, but things in the lower mantle will not erupt through magma, and humans can't dig this deep at present, so what this layer is is unknown.

It is 4.8 million meters underground and reaches the core area, which is called the outer core. 2 million meters away from the upper mantle is an ocean of iron, all of which are rolling molten iron.

This is only through speculation about the earth's magnetic field. Without such a large amount of metal, it is impossible to form such a large earth magnetic field.

The last remaining central part is the core of the earth's core. The core of the earth is a huge iron ball with infinitely high temperature. The temperature is higher than the liquid iron outside, but it becomes solid due to greater pressure.

Horribly, scientists have found that when the earth was born, the iron ball in the core did not exist, but was formed about one billion years ago.

In other words, the core of the earth is getting stronger and stronger, and this core will get bigger and bigger until the ocean of 2 million meters of liquid iron becomes stronger after countless years.

If this happens, then the earth will have no magnetic field. Without a magnetic field, the atmosphere on the earth's surface will be blown away by the solar wind in an instant, and all living things will die because of ultraviolet rays.

At that time, the only way out for mankind may be to escape to the underground and continue to live as an underground person, or will the underground world be occupied by other creatures?

Humans know too little about the underground world, so it may be more mysterious to us than the universe and the ocean.
