How terrifying is the "god-level civilization" in the universe? They can easily destroy the galaxy, where are they?

Kardashev Civilization Index

The universe has existed for nearly 13.8 billion years, and humans only appeared 2 million years ago. Obviously, in the evolution of the universe, In the process, it is very likely that many civilizations that are more powerful than human beings have been born. Of course, after humans, there may be new civilizations emerging.

Therefore, Kardashev imagined the levels of alien civilizations. If alien civilizations exist, then they can be roughly divided into three levels. Among them, as early as 1960, Dyson proposed that The "Dyson sphere civilization" that controls stellar energy ranks second among them.

Let’s take a look at the specific division: The first stage is the home star civilization. At this stage, it is very difficult for the civilization to leave the home star, and the available resources are all from the home star. If Star can break through this civilization stage, then it will have a chance to become a second-level civilization - a star system civilization.

We have already mentioned the strength of the star system civilization above. To put it simply, everything in the entire star system can be taken as your own. This is also a level in human dreams. To put it simply, mankind is currently in the first stage of civilization and is working towards the second stage of civilization.

Then came the interstellar civilization. In this stage of civilization, it is no longer limited to the star system where it is located, and can freely come and go in the large galaxy where it is located. Continuing to take human beings as an example, if human beings reach this level of civilization in the future, then human beings can come and go freely in the galaxy.

However, strictly speaking, Kardashev is an astronomer after all. When he studied the classification of cosmic civilizations, he was relatively conservative. In fact, many people now believe that, except for In addition to the above three civilizations, it is very likely that there are "god-level civilizations" in the universe, which are more advanced civilizations. This kind of civilization can also be called the "fourth-level civilization" stage. So, what will they look like? Woolen cloth?

"God-level civilization" in the universe

Since it is envisaged that the third-level civilization in the universe can freely roam the large galaxies where it is located, then, the "god-level civilization" in the universe "God-level civilization" will obviously not be bound by large galaxies and can go to other large galaxies.

Let’s use humans as an analogy: If humans break through the third-level civilization in the future and become a “god-level civilization”, then humans will not only be able to come and go freely in the galaxy, but humans will also be able to travel Andromeda Galaxy and more. Of course, human civilization at this time may have been scattered throughout the universe.

How powerful is the "god-level civilization"? On this issue, we still need to look back at Kardashev’s civilization conjecture. According to research, Kardashev believes that if the level of civilization reaches level one, it can have energy 10 billion times higher than the current energy. If the ability of level three civilizations in the universe can control entire large galaxies, Then, a "god-level civilization" can control at least 10 billion large galaxies.

What does this mean? When the third-level civilization in the universe successfully breaks through and transforms into a "god-level civilization", then, assuming that there is a civilization in another large galaxy that he thinks may be a threat to him, he only needs to drop a weapon at random , then another large galaxy may disappear into the universe.

In other words, for a "god-level civilization", the entire universe may be a "playground". Civilizations at this stage may have already fully understood all the mysteries of the universe.

Is there really a "god-level civilization"?

If you want to answer this question, you need to look at how long it takes for civilization to advance by one level. Strictly speaking, the current level of civilization that humans are at is not enough to realize the civilization of their home planet. After all, humans have many unknown things on earth. Humans only know 50% of the land and even less of the oceans. , only 10%.

This means that humans still have a long way to go if they want to reach the home star civilization mentioned by Kardashev. How long will this stage take? The answer is about 5,000 years later.

In the past ten thousand years since humans entered primitive agricultural society, humans have gradually learned how to use part of the energy on the earth to meet our increasingly huge energy needs. However, this is very important for human development. It is far from enough, because if we only rely on the resources on the earth, humans may not be able to immigrate to Mars.

Therefore, in order to develop, humans need more energy. Assuming that humans in 5,000 years can become a home planet civilization, then humans are only the lowest first-level civilization. At this stage, they are far away from the gods. level civilization, there are three more levels.

How long will this take? Controlling the earth is the easiest, but it is much more difficult to control the entire solar system, not to mention taking the resources of the entire star system for yourself. Unfortunately, humans may never be able to achieve a second-level civilization, even if it is achieved , it may take at least tens of thousands of years or even longer.

If it is to rise from a star system civilization to an interstellar civilization, it will take even longer, and it may take hundreds of millions of years. Of course, it will be more difficult to break through to a god-level civilization, although the universe already has 138 It has a history of hundreds of millions of years, but in fact, the birth and evolution of civilization is not that easy. It is very likely that many civilizations will die at the stage of first-level civilization or second-level civilization.

Why is this happening? Take the current situation of human beings as an example. Human beings have developed rapidly in the past 200 years, but humans are also destroying the earth, causing scars on the earth. Many natural landscapes on the earth have been greatly changed due to human intervention. At the same time, the biodiversity of the earth has also been affected.

Today, the prospects for human development are no longer optimistic. For example, many researchers believe that in about 100-200 years, if humans still have no way to control the earth, then humans will be on the earth. Gradual extinction also means that humans may never be able to leave the earth, let alone rule the solar system.

The development of other civilizations may be similar, what do you think?
