Hundreds of years ago, human civilization embarked on the road of industry, and since then began a period of rapid development. With the help of science and technology, mankind has also ushered in opportunities for qualitative change, bringing the entire civilization onto the fast lane. In just a few hundred years, we have achieved leaps again and again, not only improving the quality of people’s lives, but also Realized the wish of the ancients, stepped out of the earth and began to explore the universe.
The universe once was a completely inaccessible field for humans, but with the help of technology, we finally left traces of human activities in the vast starry sky. Faced with the vast universe, both the earth and human beings are undoubtedly very small. Such a small earth can give birth to human beings. Such a vast universe and starry sky, with countless galaxies and countless planets, should not lack intelligent civilization.
So are there many alien civilizations in the vast universe? When human beings just walked out of the earth, we all believed that the starry sky in the universe should be very lively. Even if there are not all alien life and alien civilization everywhere, then the traces of alien civilization should be visible in the universe.
However, the actual situation is different from what we imagined. After truly walking out of the earth, what we see is a dark, cold and extremely lonely universe. It should be a very lively universe, but the reality is very quiet. Not to mention intelligent civilization, even simple microorganisms have not been discovered until now.
If there are many alien civilizations in the universe, there must be many civilizations that have also entered the age of technology, and some civilizations may have been upgraded to interstellar civilizations. For a civilization that walks out of the planet to the starry sky, it is normal to leave traces of activity in the universe, especially a powerful interstellar civilization, it is more likely to leave traces of its own activities in the entire galaxy or in different galaxies.
As long as we can find the traces of an extraterrestrial civilization, we can prove the existence of an extraterrestrial civilization. Then, have we discovered such civilization traces? Until now, there has also been no discovery. In the starry sky area that humans can explore and observe, we have not found any objects or traces related to civilized activities.
This huge contrast between expectations and reality is the core content of the “Fermi Paradox.” In order to explain this weird situation, scientists have also put forward various interesting and subversive hypotheses. For example, some people have speculated that this universe may be a virtual universe created by an advanced civilization, and we are just a bunch of code.
Among the many subversive hypotheses, one hypothesis has aroused intense discussion among people. This hypothesis holds that humans are not natives of the earth, but come from the universe. Hundreds of thousands of years ago, the alien civilization sent some criminals to the earth, and the earth became the “prison” for this civilization to imprison mankind.
The “prisoner” of an alien civilization subverts people’s cognition. It sounds a bit sensational. Many people are unwilling to believe that how can such a great intelligent civilization of mankind be a “prisoner” of an alien civilization? The scientist who put forward this bold conjecture also did not speak completely nonsense, but put forward some of his own reasons and opinions.
This reason is that human beings cannot fully adapt to the earth’s environment. We all know that life is a long evolutionary path from simple to complex, and all kinds of complex creatures on the earth are actually evolved from primitive life after billions of years of evolution.
The purpose of evolution is to adapt to the earth’s environment. Only organisms that can fully adapt to the earth’s environment can not be eliminated by nature. Therefore, we will find that most organisms on the earth have strong environmental adaptability. Mammals that are homologous to humans are also particularly adaptable to the environment and will not easily get sick.
On the other hand, human beings are different. We cannot really fully adapt to the ecological environment of the earth. For example, we are extremely sensitive to strong light. The most difficult thing for human beings to fully adapt to the earth’s environment is the earth’s gravity.
We all know that every planet has its own gravitational environment, and the creatures living on this planet can theoretically fully adapt to the gravity of this planet after billions of years of evolutionary evolution. Animals on the earth have basically achieved this, but humans have not fully achieved it. Under the influence of the earth’s gravity, humans often feel discomfort. For example, when the elevator is fast, we will feel discomfort.
For another example, when we take a spacecraft out of the gravitational restraint of the earth, most people cannot adapt. Only a few people with stronger physical fitness can adapt. That’s why we are very strict when selecting astronauts, and we have very high requirements for physical fitness.
At the same time, the influence of gravity will also cause various diseases of the cervical spine, spine and internal organs in humans, and these diseases rarely or do not occur in other animals. If human beings are truly aboriginals on the earth, after billions of years of evolution, they should have adapted to the earth’s gravity environment and other environments long ago, but in fact, the earth’s gravity has a relatively large impact on the human body. .
This view also believes that after the alien civilization sent the “prisoner” to the earth and left, it also left a “monitor”, which may be the moon as we know it. As for the moon, I believe you will not be unfamiliar with it. It is the only natural satellite of the earth.
The moon has always been a mysterious little planet. First of all, its mass is relatively large, which is very rare in satellites. At least so far, scientists have not discovered a second such large satellite. In addition, although there are many craters on the moon, those craters are also very weird. They are usually relatively large in area, but the depth is very shallow.
The large and very shallow lunar crater means that there is a very hard protection under the lunar soil, and some scientists have speculated that it may be a tight metal shell. According to the detection of the moon by the current probe, the metal content on the moon is very high, especially the content of titanium metal may be more than 10 times that of the earth.
Titanium metal has good corrosion resistance, high temperature resistance and sturdiness, which is very suitable as the “coat” of spacecraft. Therefore, some scientists suspect that the moon may be a high-tech creation, and its role is to monitor humans on the earth.
After reading this, many people may also think that the “Earth Prison Theory” seems to have some truth, but so far all this is just conjecture. Some opponents believe that the distance between the vast universe and the starry sky is in light years, and the speed of objects cannot exceed the speed of light, so it seems very unreasonable for alien civilizations to take a long time to cross the interstellar to send prisoners to the earth.
To unravel these mysteries, then perhaps we need to focus on the moon. If it is an artificial spacecraft, then there must be something else inside the moon. As long as we truly understand whether the moon is a celestial body or a man-made object, we may Part of the answer can be obtained. All this requires the continuous efforts of mankind. Only when our technology is more advanced can we hope to fully explore the moon and find the truth.
