Core. Not only is the internal pressure high, but the temperature is also very high, estimated to be as high as 2 000-5 000, and the density of the substance is on average 10?6 grams between centimeters x centimeters x centimeters.
In the case of high temperatures, pressures and densities, the concepts of "solid" or "liquid" are no longer applicable.
This is because the material in the earth's core has both the "rigidity" of steel and the "flexibility" (plasticity) of ash and asphalt. Not only is this substance more than ten times harder than steel, but it can also slowly deform without breaking.
These special cases inside the Earth's core are difficult to simulate even in the laboratory, so little is known about them.
But there is one thing that scientists are convinced of: the interior of the earth is a world of extreme unrest, and all kinds of materials in the interior of the earth are always in constant motion.
Some scientists believe that the layers of matter in the earth's interior not only have a local flow in the horizontal direction, but also have convective movements between the top and bottom, but the speed of this convection is very small, only about 1 cm per year. Some scientists have also speculated that the material inside the Earth's core may be subjected to the gravitational pull of the sun and moon and cause rhythmic vibrations.

Humanity currently does not have the technology and ability to get to the center of the earth, because the Earth's interior is extremely complex, including high temperatures, high pressures, and other extreme geological conditions, making it an extremely challenging task to get directly into the center of the earth. Here are some of the main reasons that hinder exploration of the center of the earth:
1. Extremely high temperature:The temperature of the Earth's interior gradually increases with depth, and the Earth's core is estimated to be thousands of degrees Celsius or even higher. Current human technology is not able to withstand and cope with such a high temperature environment.
2. Extremely high pressure:The pressure on the Earth's interior also increases with depth, beyond what humans can currently withstand. Even if we are able to withstand high temperatures, we will need to face extreme crustal pressures, which is an insurmountable problem for humans.
3. Resource and technical limitations:Achieving geocentric exploration requires a lot of resources, money, and advanced technology. At present, our technical level has not yet reached a sufficient level of maturity and reliability, and we lack sufficient resources to support such a huge project.
4. Challenges of living conditions:The geocentric environment lacks the conditions necessary for human survival, such as oxygen, water, and food. Even if we can overcome the challenges of high temperatures and high pressures, we need to solve the problem of human survival and ** in this extreme environment.
To sum up, due to the limitations of technology, resources and living conditions, human beings are currently unable to directly explore the center of the earth. However, scientists are working to study and understand the structure and properties of the Earth's interior through means such as wave propagation, geological exploration, and probes to improve the understanding of the Earth. These efforts have helped to unravel the mysteries of the Earth's interior, but it remains a distant dream to get directly to the center of the Earth.

The interpretation upstairs is ruthless and detailed, and I can't help but think of it, pressure cooker, well, that's it.
-
With the current level of science and technology, why don't human beings explore the center of the earth? Is that necessary?
-
So far, human drilling activities have been in the earth's crust, and the deepest is about 10 kilometers.
The center of the earth is the core of the earth.
The common name refers to the central part of the earth, with a radius of about 3,480 kilometers, mainly composed of iron and nickel elements.
Compose. Its physical properties are distinctly different from the surrounding mantle and crust. Abbreviation for Earth's center of mass. The origin of the Earth's frame of reference is defined in a common center of mass that includes the solid Earth, the atmosphere, and the oceans.
The center of the earth is divided into two parts: the inner heart and the outer center.
The Mystery of the Center of the Earth. As we all know, the earth is composed of three parts: the crust, the mantle, and the core, but this understanding should be said to be very superficial. Because according to the current state of science and technology, human drilling is only 35 kilometers deep, and the deepest exploration well (on the Colis Peninsula) is only 12 kilometers.
The radius of the earth is 6,300 kilometers, and when we compare these numbers, we will find that the earth we touch is actually like the peel of an apple cut with a knife, limited to a thin layer. So what's further underground? What is inside the Earth, and even at the center?
This is a mystery that has puzzled people for thousands of years.
However, human beings are not ignorant of the earth, and intelligent human beings are constantly looking for answers to their questions in the depths of the earth according to the changes in the movement of the earth.

The center of the earth is still a mysterious place for humans, why have humans been unable to detect the center of the earth? There are two reasons why humans have done everything so far. The first is the power that does it, and the second is the economy.
Any progress in science and technology can be traced back to these two points. Digging up the earth, first of all, science and technology should be unattainable at present. Manpower and material resources are also not allowed.
And there isn't much benefit to economic value. Western hegemony, like a certain country, is also not beneficial to its status as an "international policeman" on the planet. Therefore, there is no need for human beings to dig up the earth in terms of technology and purpose.
And, digging even deep into the earth can lead to a domino effect in various climates. It could even lead to a series of disasters. First and foremost, changes in crustal pressure can lead to active volcanic eruptions and tectonic plate movements on Earth**.
And then the tsunami and everything are like a French meal, one by one.
Even with technology, I don't think any civilization of the current level would do this. The diameter of the ball is 12,756 kilometers, and the radius is 6,378 kilometers, that is, 6,378,000 meters, to reach the center of the earth. Got it, how big a hole do you have to dig?
The current well-drilling technology of human beings is only 10,000 meters, so where is this? It's not that human beings don't want to dig up and see, it's that human beings haven't reached this level of science and technology. Human capabilities can't do that.
The Mariana Trench does not need to be dug, more than 11,000 meters, which is equivalent to a small scratch on the skin of an apple on the earth, and it is difficult for humans to get down. In the dimension of cosmic exploration, the current level of science and technology of human beings is like a baby who has just been born for a few seconds and has not yet cut the umbilical cord, and even knows less than 1 in 100 million about the earth itself, almost zero. The huge amount of energy released by the earth's core is unbearable for human beings, and it may cause a series of problems such as the rapid increase in the earth's temperature.
And we don't have the ability to make a tool that can withstand such high temperatures. So with this idea, there is no way, curiosity can kill cats, but not people.
-
Probably because the distance from the center of the earth to the ground is too far to be detected at this distance.
-
Because the task of exploring the center of the earth has no substantive and concrete significance, and there is no follow-up funding, they are all abandoned.
-
1. Current technology cannot penetrate into the interior of the earth. 2. In the known scientific and technological knowledge, human beings cannot use scientific and technological means to resist the hot temperature from the earth.

The interior of the earth is divided into three parts: the crust, the mantle, and the core of the earth, in addition to the crust, the temperature of the mantle and the core of the earth are very high, basically in a molten state, so the reasons why human beings cannot get through the center of the earth are as follows:
First, the temperature is too high, and the punching equipment can not withstand it. If the drilling equipment needs to be operated by pure punching, the personnel will not be able to withstand the high temperature.
Second, the liquid mantle cannot be perforated. Suppose drilling into the mantle is equivalent to a volcanic eruption. There is no such thing as a borehole for liquid substances.
Why haven't humans been able to fly out of the solar system so far? Once you make a mistake, the probability of being rescued is zero.

In this case, some of the problems are that you do not have a design foundation, not an art major, if you want to enter, you should first learn the knowledge of design, such as: color principle, plane composition, three-dimensional composition, pattern basics and other courses. Otherwise, you can only be an operator, and there is no future. >>>More
1. The scientific and technological revolution promotes the transformation of the mode of production. First of all, the development of science and technology has promoted the transformation of labor materials, for example, the development of iron-making technology has made iron tools used in agricultural production, replacing stone tools; The use of mechanical agricultural machinery replaces manual farming tools. Second, science and technology promote the transformation of the object of labor. >>>More
The speed of human development should be faster and faster, because the level of education and science and technology of human beings has been greatly improved, so the speed of development is also getting faster and faster. However, this growth rate cannot be sustained forever, showing a wave-like development trend, with one stage developing faster and another stage developing slower.
