The Kardashev civilization index universe has existed for nearly 65.438+038 billion years, and the time when human beings appeared was only 2 million years ago. Obviously, in the evolution of the universe, it is very likely that many civilizations more powerful than human beings have been bred. Of course, after mankind, there may be new civilizations constantly emerging. Therefore, Kardashev conceived the level of alien civilization, giving way to the existence of alien civilization, so they can be roughly divided into three levels, among which Dyson's "Dyson Sphere Civilization" proposed as early as 1960, which can control the energy of stars, ranking second. Let's look at the specific division: the first stage is the parent star civilization. At this stage, it is difficult for civilization to leave the home star, and all available resources come from the home star. If we can break through this stage of civilization, we will have the opportunity to become a secondary civilization-stellar civilization. The strength of the stellar civilization, as we said above, is simply that everything in the entire stellar system can be taken for yourself, which is also a level in the human dream. In short, mankind is currently in the first stage of civilization and is striving for the second stage of civilization. Then there is interstellar civilization. At this stage of civilization, it is no longer confined to its own star system, but can come and go freely in its own big galaxy. Continue to take humans as an example. If humans reach this level of civilization in the future, then humans can come and go freely in the galaxy. But strictly speaking, Kardashev is an astronomer after all, and he is conservative when studying the classification of cosmic civilization. Its realization is believed by many people that in addition to the above three civilizations, there is probably a "divine civilization" in the universe, that is, a more advanced civilization. This civilization can also be called the "four-level civilization" stage. So, what will they look like? Since the "god-level civilization" in the universe is envisaged, the third-level civilization in the universe can roam freely in the big galaxy where it is located, so it is obvious that the "god-level civilization" in the universe will not be bound by the big galaxy and can go to other big galaxies. Take human beings for example: if human beings break through the third civilization and become "sacred civilization" in the future, then human beings can not only come and go freely in the galaxy, but also go to the Andromeda galaxy to find out. Of course, human civilization at this time may have been scattered in the universe. How powerful is the "god-level civilization"? On this issue, we still need to look back at Kardashev's conjecture of civilization. According to the research, Kardashev thinks that if the civilization level is raised to the first level, it can have energy 65.438+000 billion times higher than the existing energy. If the ability of the third civilization in the universe can control the whole galaxy, then the "sacred civilization" can control at least 654.38+000 billion galaxies. What does this mean? When the third-level civilization in the universe successfully breaks through and becomes a "divine civilization", then assuming that there is a civilization in another big galaxy that he thinks may pose a threat to himself, throwing a weapon casually, then another big galaxy may disappear into the universe. In other words, for "sacred civilization", the whole universe may be a "playground", and the civilization at this stage may have thoroughly understood all the mysteries in the universe. Will there really be a "sacred civilization"? If you want to answer this question, you need to see how long it will take for civilization to upgrade. Strictly speaking, the current level of civilization of human beings is not enough to realize the civilization of their home planet. After all, on earth, there are still many unknown things for human beings. Only 50% of them know the land, let alone the ocean, only 10%. This means that there is still a long way to go before human beings can reach what Kardashev called the home planet civilization. How long will this stage take? The answer is about 5000 years later. Since mankind entered the primitive agricultural society, in the past ten thousand years, mankind has gradually learned how to use part of the energy on the earth to meet our growing energy demand. However, this is far from enough for the development of human beings, because if we only rely on the resources on the earth, human beings may not be able to migrate to Mars. Therefore, in order to develop, human beings need more energy. Assuming that after 5000 years, human beings can become the home planet civilization, then human beings are only the lowest civilization. At this stage, there are still three levels from the divine civilization. How long will this time take? Controlling the earth is the simplest, but it is much more difficult to control the entire solar system, let alone take the resources of the entire star system as your own. Unfortunately, human beings may never realize the second-class civilization, and even if they do, it may take at least tens of thousands of years or even longer. If it is from stellar civilization to interstellar civilization, it will take longer, maybe hundreds of millions of years. Of course, it will be more difficult to break through the sacred civilization. Although the universe has a history of 65.438+038 billion years, in fact, the birth and evolution of civilization is not so easy. Many civilizations are likely to die in the first or second civilization stage. Why is this happening? Take the human category as an example. In the past 200 years, human beings have developed rapidly, but they are also destroying the earth, causing the earth to be scarred. Many natural landscapes on the earth have undergone tremendous changes because of human intervention, and at the same time, the biodiversity on the earth has also been affected. Today, the prospect of human development is not optimistic. For example, many researchers believe that in about 100-200 years, if humans can't control the earth, they will gradually become extinct on the earth, which means that humans may never leave the earth, let alone rule the solar system. The development of other civilizations may be the same, don't you think?
