The earth is a rocky planet, except for the high-altitude in the atmosphere, it is mainly composed of a solid structure. This zero-solid structure is divided into three layers, namely the crust, the mantle and the core. Their thickness is different. The thinnest crust is about 17 kilometers, and the core is 3400 kilometers thick.
The earth core can be divided into an inner core and an outer core. The outer core is mainly composed of liquid material, which forms a flow, while the inner core is a high-density metal body composed of iron and nickel. The mantle layer sandwiched in between is the most mysterious place. Scientists once thought that the mantle is made of liquid material and the magma erupted by volcanoes came from here. However, in recent years, scientists have discovered through seismic detectors that the mantle layer seems to have a huge solid state. Mountain peaks are not entirely composed of magma.
After mankind entered the age of science and technology, we ushered in a period of rapid development. With the help of science and technology, we walked out of the earth and began to explore the universe. Today, humans can observe a part of the scene tens of billions of light-years away through astronomical telescopes, and human probes have walked out of the heliosphere and entered interstellar space.
Mankind’s in-depth exploration of the universe and the speed of development are astonishing, but looking back, we still know very little about the earth. Humans live on the surface of the earth, which is the uppermost structure of the earth’s crust, while land only occupies 29% of the surface area, and the rest are oceans. We don’t know much about the ocean, only 10%, and the remaining 90% are mainly concentrated in the deep ocean.
Compared with the ocean, we can still have a certain understanding, so the situation inside the earth is basically a blind spot for us. Many friends may say, don’t we already know the three internal structures of the earth and the structure of the earth’s core? In fact, many of these cognitions are still just speculations. For example, what is the situation with the earth’s core? We don’t have a definite answer, we just guess that it is composed of inner and outer cores.
As for the understanding of the mantle, more judgments are made through changes in seismic waves, and such judgments themselves have many flaws. To truly understand the situation inside the earth, the probe must be able to penetrate deep into the earth. That is, we have to dig down to the inside of the earth, even into the depths of the earth’s core.
So can human beings have the ability to dig into the earth’s interior? The madness of scientists is beyond the imagination of many people. In the last century, the United States and the Soviet Union started a race in various fields. In the field of space, the Soviet Union achieved two firsts, the successful launch of mankind’s first artificial satellite, and mankind’s first space flight. Crew enters space. Not to be outdone, the United States launched the Apollo project and successfully achieved the first manned landing on the moon in 1969.
After completing the space race, the United States and the Soviet Union started a race to explore the interior of the earth. The United States chose to dig down into the interior of the earth in the ocean. However, due to various difficulties, this plan was eventually aborted. The Soviet Union was smarter and chose Dig down holes on land.
This Soviet digging experiment caused a sensation in the world at that time. A large number of scientists gathered here to conduct the first human exploration of the earth’s interior. The Soviet scientist’s illusion was to dig through the earth. Can this madness be realized? We all know that the radius of the earth is about 6371 kilometers. To dig through the earth, a drill pipe with a length of more than 12,000 meters must be prepared.
Of course, there is no problem with the drill pipe. It can be realized by splicing no matter how long it is. The main reason is that we need a super drill bit, which is the key to deciding whether to dig down. The Kola ultra-deep drilling experiment in the Soviet Union started in 1970. The first 9 years were relatively smooth, and it quickly dug tens of thousands of meters. This result encouraged scientists to dig deeper with the information.
However, in the ensuing time, the speed of digging became slower and slower, and it took ten years to dig only more than 200 meters. Why is this so? The main reason is that as the depth continues to increase, the temperature inside the earth is also rising. It must be known that the inside of the earth is also in a high-pressure and high-temperature environment, and the temperature can reach 6000 degrees Celsius.
Under the influence of increasing temperature, the drill pipe and the drill bit continue to soften and fracture, which brings difficulties to the drilling process. Often only a little bit is drilled, and the drill bit needs to be replaced. This continued for 22 years and dug an ultra-deep hole with a depth of 12,262 meters. By 1983, the Kola ultra-deep drilling experiment was stopped, and the hole was closed. There are many mysterious legends about the reason for the stop of the experiment.
In fact, the real reason was that it was unable to proceed. The temperature at a depth of 12,262 meters was unbearable by the existing drill materials. If it went down, it was broken by the software. And this depth has become the deepest hole dug in human history. Although this experiment has stopped, it has made a great contribution to mankind.
A friend once asked: If we keep digging towards the inside of the earth, can we dig through the earth? Perhaps many friends, after learning about the Kola ultra-deep drilling experiment, thought it was impossible and humans could not do it. If you think so, you are wrong. The power of science and technology is endless. As long as we solve the problem of high-temperature materials, digging through the earth is no longer a dream.
The temperature inside the earth is not as terrible as we think. Even the temperature at the core is only about 6000 degrees Celsius. This temperature is definitely an insurmountable difficulty for humans’ current technology. However, with the rapid development of human science and technology, we will inevitably have high-temperature drill materials that can withstand this temperature in the future.
As long as you have this high-temperature material, you can dig down until you dig through the earth. So from a scientific point of view, digging through the earth is not a myth, but just a matter of time, depending on the speed of human science and technology development.
Of course, even if humans have the technology to dig through the earth in the future, we will not be able to do it. That crazy idea will bring disaster to the earth and mankind, so what kind of disasters will there be? Friends are welcome to leave a message below to discuss and express their opinions and opinions.
