The earth is a rocky planet and the homeland where mankind has survived for millions of years. After mankind entered the age of science and technology, we finally walked out of the earth through the power of science and technology and saw the vast universe. At the same time, we can clearly recognize the appearance of the earth from space. Seeing the earth from space, the earth is a spherical object.
We also understand at this time that the earth has a surface and an underground. Humans and most living things live on the surface of the earth. And what does the inside of the earth look like? For many people, we have many ways to explore the surface of the earth, especially with satellites, it is more convenient to explore the surface of the earth.
But for the exploration of the earth’s interior, we don’t have any good methods. Except for the fuzzy detection of seismic waves, a more effective method is to dig down. Only by digging deep into the earth can we truly understand this underfoot. world.
I believe many friends are aware of the US-Soviet race in the last century. At that time, the United States and the Soviet Union were the first to have a space race. In this contest, the Soviet Union achieved two firsts: one sent a satellite into space, the first time. The astronaut was sent into space. The United States has achieved the first manned landing on the moon. In this space race, the United States and the Soviet Union are divided among themselves, each with a thousand teams.
After the end of the space race, the United States and the Soviet Union began a competition on the earth. The project chosen at this time was to dig through the earth. For scientists, exploring the mysteries of the earth’s interior is a matter of great interest, and it is also very important for mankind. One thing.
The United States chose to drill offshore because the ocean is the closest place to the earth’s crust, and from here it can reach deep into the earth’s crust. Although the idea is good, in the actual operation process, American scientists found that drilling from the ocean to the crust is far more difficult than we imagined. Later, due to funding, technology and other reasons, this underground drilling experiment in the United States was not carried out.
Although the United States gave up underground drilling experiments, the Soviet Union did not give up. In 1970, a large number of Soviet scientists began to enter the extra-terrestrial drilling experiments, which we call the Extra-Kola ultra-deep drilling experiment. This experiment shocked the world at the time. It was an astonishing “crazy project”. These scientists decided to realize their dream of opening up the earth through the highest technology available today.
But in the end, I believe my friends all know that the Kola ultra-deep drilling experiment was carried out for 20 years, and finally the drilling was forced to stop when it reached 12,262 meters. The reason for the termination of this experiment was not that there was a terrifying sound from deep underground, as in folklore. The main reason is that it cannot be drilled anymore. We must know that the earth is composed of three parts, namely the crust, the mantle and the core. The earth’s crust is the outermost layer of the earth’s solid circle. It is a solid shell composed of rocks, and the texture is extremely strong and difficult to be destroyed.
As the depth continues to increase, the temperature inside the earth is getting higher and higher, and the pressure is getting higher and higher. The temperature of the core at the very center can reach 8000 degrees Celsius, and human drill materials can not withstand the high temperature and high pressure environment inside the earth, and they can only be forced to stop in the end. Many people here will have such an idea: If the power of science and technology is strong enough, we dig through the earth, what will happen?
Humans cannot penetrate the earth, mainly because there is no more powerful high temperature resistant drill material. However, if such materials are realized in the future with the rapid development of science and technology, it will not be difficult to drill through the earth. This is the power of science and technology. It may seem to many people that if we have penetrated the earth, we can establish underground passages, which can not only explore the interior of the earth, but more importantly, we can travel straight to all corners of the earth.
Between the two points, the straight line is the shortest. We are now going from the southern end of the earth to the northern end, and we need to make a circular motion to reach it by plane. But if you go straight from the opened underground passage, the time required will be very short. It used to take tens of hours, but now it only takes tens of minutes. This is indeed a very fast channel.
So if human beings have such technological strength, can they really dig through the earth? The answer is no. If we really do this, then the consequences may be unbearable for us. We all know that the interior of the earth is not a calm, safe and stable environmental structure. Although we see that the surface of the earth is very stable and calm, once we walk into the interior of the earth, you will find that it is a world of lava.
The interior of the earth, especially after reaching the mantle layer, is no longer a solid structure, but in a liquid state where lava flows. We can imagine this as a half-boiled egg. When an egg is boiled to half-mature, the egg white is naturally solid, which is equivalent to the earth’s crust, while the original yolk is in a viscous liquid state. This is equivalent to the mantle and core structure below the crust.
Moreover, the interior of the earth is still an ultra-high pressure environment, with a pressure of 3.7 million atmospheres in the center. In such a high-pressure internal environment, once the earth is dug through, what will happen? The lava material inside must be ejected by strong air pressure. The magma erupting from the inside is far more powerful than we imagined a volcanic eruption.
At that time, the earth will become a world of fire, a large amount of magma will be ejected, and a large amount of carbon dioxide will be released at the same time, and a large amount of volcanic ash will cover the sky. At this time, the earth will enter the era of doomsday, the mass extinction of living things will begin, and human beings will not be able to continue to survive on the earth. In addition to this, once the earth is dug through, the leaked air pressure may also cause some minor changes in the earth’s rotation and revolution.
Even a very small change may destabilize the planetary system of the entire solar system. At that time, it might not be possible for the earth to collide with other planets. This shows that even in the future of advanced technology, we can’t do things like digging through the earth. But if in the future, when human technology can dig through the earth, it is inevitable to go deep into the earth to explore.
At that time, scientists may dig into the mantle layer, and then establish a stable and safe passage, allowing people to take a safe device to enter the earth’s interior for sightseeing, which is similar to the submarine passage we are building now. Therefore, the power of science and technology is infinite. As long as science and technology are sufficiently advanced, nothing is impossible. Of course, the power of science and technology is also terrifying. If it is used carelessly, it may bring a devastating crisis to the entire human civilization.
