The earth is a rocky planet. Standing in space, we will see a beautiful blue sphere. It is the home earth where mankind has survived for millions of years. Before entering the age of science and technology, the ancients did not know what kind of world the earth was, and where humans lived in this world.
It was not until mankind embarked on the path of scientific development that we gradually understood that mankind did not really control the earth, and the place where we live is only the surface of the earth. There are two places on the earth that are still not controlled by human beings, one It is the ocean world, and the other is the underground world.
Regarding the ocean, everyone knows that 71% of the earth’s surface is made up of oceans, but humans’ understanding of the oceans is actually very little, only about 10%. What kind of secrets are hidden in the deep ocean? We still don’t know. know. Compared to the ocean, the secrets of the earth’s interior are more attractive to us.
We all know that according to modern scientific research, the earth is mainly divided into three parts: the crust, the mantle and the core. The crust is the outermost region of the earth. The average thickness is about 17 kilometers. Humans live in the outermost layer of the crust. Although humans have walked out of the earth 50 years ago and began to explore the universe, our understanding of the earth’s interior is still very good. Few, and legends about the underground world have existed since ancient times, but we have not yet uncovered this mystery.
What is inside the earth, whether there is a mysterious underground world, we don’t know yet. Humans’ only knowledge of the Earth’s interior is limited to the crust, mantle and core. The crust is 17 kilometers thick. In such a thick area, whether there is a huge underground cave world is still the next unknown.
As for our understanding of the mantle, we think that it is a liquid world where magma flows, but the truth of the matter remains to be further explored. There are legends about the existence of the underground world from ancient times to the present, and there are also many theories about the connection between the surface and the underground world.
In the “Science Reports” magazine, there was an article in which scientists discovered a huge “river” under the surface of Australia. This river is a hidden seabed river that only appears in autumn and winter. The entire river spans 10,000 kilometers, and there are many special exceptions. The discovery of this river also caused a sensation in the scientific community.
Some scientists speculate that this river may be a channel connecting the new underground world. For the discovery and research of this flowing river, scientists have spent more than 2500 day and night explorations. At present, there is not much knowledge about this mysterious river, only that its water density presents a “staircase” shape, and the density in some areas is very high. , The density in some areas is very small, and it only appears in autumn and winter.
Why does this river only appear in autumn and winter? Scientists believe that it may be related to temperature changes in Australia. It is the river of comrades that changes with seasonal changes, so scientists suspect that it is equivalent to a channel in itself, connecting the depths of the earth. As for where it leads, it is not yet known and needs to be changed. Further exploration research.
The ocean is the area closest to the mantle. Scientists have found that the seawater on the earth’s surface has been flowing into the earth’s interior for a long time. Every year, hundreds of millions of tons of water flow into the crust and even the mantle layer through the gaps at the bottom of the ocean. .
The existence of water inside the earth is a fact beyond doubt, but in what form the water inside the earth still exists, further exploration is needed. Some scientists believe that the water inside the earth dissolves in magma and forms a water cycle with the surface. Other scientists believe that there may be a huge mysterious space inside the earth, where water from the surface will converge in this space to form an underground ocean.
As for the research and exploration of the mantle layer, scientists have made new progress in recent years. According to the American Geophysical Union report, scientists have discovered giant mountains in the interior of the earth and mapped out the conditions of the mountains through 3D images. The scientists found that, The entire mountain is 100 times higher than Mount Everest.
This underground giant mountain is located in the mantle layer. It is necessary to know that the mantle layer is a world of high temperature and pressure. In theory, there should only be flowing magma here. How can there be peaks? However, through the exploration of seismic waves, it is indeed found that there are such giant peaks in the mantle layer, but at present there is no answer to how it was formed.
The discovery of giant mountains inside the earth once again made people full of expectations for the existence of the underground world. Scientists believe that this mountain inside the earth may be the biggest secret of the earth. It may be one of the main factors forming plate tectonics. It may also have a certain relationship with the formation of ecosystems on the earth’s surface and the formation of life.
Combining these circumstances, many people think that the earth is not as simple as we imagined. There is a rich world of life on the surface and a rich world of marine life in the ocean. It is possible that there is also a world of subterranean life that we do not understand at all in the earth.
Although we don’t know whether there is a huge space inside the earth, the existence of life under the earth is indeed confirmed by scientists. In the past 10 years, scientists have discovered a large number of various kinds of life underground through a lot of research and exploration. The abundance of underground life far exceeds our estimates. It can even be said that only in terms of quantity, underground life can be called Is the overlord.
Moreover, scientists have discovered various kinds of life under some extreme environmental conditions. These lives are constantly breaking through the limits and surpassing our previous understanding of life. In 2020, scientists have also discovered non-breathing animals, life forms that can survive in a 100% pure hydrogen environment.
This important discovery allows us to realize that humans’ understanding of life is still very “shallow”, and that the ability of life to adapt to the environment is beyond our imagination. Life can survive in extreme environments that we think impossible. of. Such a discovery has important reference significance for us to search for extraterrestrial life.
As for the exploration of the underground world, mankind has just started. I believe that with the continuous advancement of science and technology, with the support of higher technological strength in the future, we can truly enter the underground world, explore the mysteries of the earth, and thoroughly understand the earth. Perhaps in the future, when we truly enter the underground world, there will be more unexpected major discoveries.
