The moment human beings walked out of the earth and saw the vast universe, we were constantly thinking about a question: Are human beings the only intelligent civilization in the universe? In the eyes of many people, the universe is vast and vast, with an observable range of only 93 billion years, the number of star coefficients that exist is at least one trillion, and the number of planets is too large to describe with numbers.
With so many star coefficients, the uncountable number of planets, and the cosmic age of 13.8 billion years, it is hard to believe that the universe does not have other intelligent civilizations. Scientists naturally also believe that there should be extraterrestrial civilizations in the universe, so when humans walked out of the earth, we started a great search for extraterrestrial civilizations.
Scientists use various methods to find traces of alien civilization. For example, Voyager 1 and Voyager 2 are sent out of the solar system. They all carry a golden record that records the coordinates of the earth and human information, as long as the Voyager is outside the solar system. Astral civilization captures, then you can know the location of the earth through the information on the record, and come to the solar system to come into contact with humans.
In addition to dispatching interstellar spacecraft, scientists also search for signals of alien civilizations that may exist in the universe, and we have also proactively sent human radio waves to the depths of the universe many times, hoping that alien civilizations can receive “calls from humans”. “. And in recent years, scientists have also observed the starry sky through astronomical telescopes, hoping to find giant alien structures like Dyson Sphere.
As long as any one of the above methods has significant discoveries, then we can determine the existence of alien civilizations. But more than half a lifetime has passed, and we have put in a lot of effort, but still nothing. There is no lively scene in the entire universe. On the contrary, the more we understand, the more we feel that the universe is lonely. Except for the earth and human beings, there seems to be no life. Information.
Many people find it difficult to accept such a result, and scientists have also put forward many conjectures. Some people think that the universe is really too big. Even if there are alien civilizations on a certain planet, the distance limits the exchanges and exchanges between civilizations.
Others think that alien civilization has developed to a very advanced stage, and they are not interested at all in low-level civilizations like human beings that have not yet reached the first level. Naturally, they will not cross the interstellar to come to the earth to come into contact with humans. These two statements can still be accepted by people. In theory, there are indeed these two possibilities. Distance is indeed a key factor restricting humans from going out. It’s easy to understand that high-level civilizations look down on low-level civilizations, and humans also look down on tiny ants.
In addition to these two conjectures, some scientists have also put forward the “Zoo Theory”, which believes that the earth and the solar system are a biological laboratory set up by alien civilizations, and humans are the “little mice” in this laboratory. The virtual universe hypothesis believes that the universe in which humans live is just a virtual universe created by advanced civilizations. Everything and life in this world are just pieces of computer program code.
These two conjectures have subverted people’s cognition, making it difficult for many people to accept, but if we think about it carefully, it may not be completely impossible. Humans keep various animals in a limited space and observe their living habits and activities. When human civilization develops into interstellar civilization, we may also use a planet or even a galaxy as a laboratory.
With the rapid development of virtual reality technology, it is entirely possible for humans to create a virtual world that makes it difficult for people to distinguish between true and false in the future. Human beings can create a virtual world in the future, so for an advanced civilization that is tens of thousands or even hundreds of millions of years more advanced than human beings, it is also possible to create a virtual universe.
These two theories are more scary. No matter how scared people are, at least the first four conjectures believe that alien civilization exists, but for various reasons we can’t reach it. In addition to these four conjectures, there is another conjecture that may be even more difficult for people to accept, that is, human beings are the only intelligent civilization in the universe.
Human beings are the only one in the universe. I believe that this kind of conjecture has scared many people. If there are no other intelligent civilizations in the universe, but only one civilization, what is the point of our exploration of the universe? The purpose of mankind’s exploration of the universe is largely to find alien civilizations, hoping to communicate with many alien civilizations.
But now you tell us, don’t look for it anymore, there is no other intelligent civilization in the entire universe besides human beings. It’s so scary to think about it. Indeed, there is only humans in the universe. Many people may seem to have nothing. Without other intelligent civilizations, humans have no competitors and can exclusively enjoy all the resources of the universe.
If you think so, then you are very wrong. Human beings are the only intelligent civilization in the universe. It really makes us think deeply. If this is the case, then there may be no meaning for humans to explore the universe, and even we have a high probability. There is no way to truly explore the mysteries of the universe.
After 13.8 billion years of such a vast universe, only the human civilization was born. The result is that we feel truly afraid. It means that no matter how big the universe is, it is possible that human beings will always be trapped in a small galaxy, and it is impossible to get out of the galaxy to explore the vast universe. It also shows that the birth of life and the birth of civilization may not be as simple as we thought.
Of course, this is just a conjecture of ours. Regardless of whether there is an alien civilization in the universe, or if there is only a civilization in the universe, we cannot give up on ourselves, but continue to advance along the path of science. Now that science has appeared before our eyes, it shows that it is the key to human beings to uncover all these mysteries.
As long as human civilization continues to develop along the path of science, whether after tens of thousands of years, hundreds of millions of years, or even tens of billions, we must move forward unswervingly. As long as we work hard, we believe that one day, All the mysteries of the universe will be revealed by us. If there is really only one civilization in the universe, we should not be afraid, but should be proud of it, showing how difficult it is for humans to emerge.
Of course, if mankind is the only intelligent civilization in the universe, it may prove the correctness of the multiverse. Standing in the universe, we think that human beings are the only intelligent civilization is a bit weird and hard to accept. But if mankind walks out of this universe and sees a vaster space with countless universes in it, then it might be easy to understand that there is only one civilization in this universe.
