Overview

To this day, human civilization has reached an unprecedented height, but if this civilization is put in the huge universe, it is just a small existence as dust.

According to scientists' observations, the universe has 13.7 billion years old . In front of it, the earth is like a child who is still learning to speak.

Since such a young earth can nurture billions of lives and civilizations, then there are many planets in the universe that are more "qualified" than the earth. Are there more advanced civilizations on those planets?

Kardashev's third-level civilization

In the 1960s, under the influence of frequent space exploration activities in various countries, an astronomer in the Soviet Union was inspired to have the idea of ​​classifying cosmic civilizations.

This astronomer is called Nicolah Kardashev . Based on the ability to obtain and consume energy, he has formulated three rating standards for cosmic civilization.

The first-level civilization is also called the parent star civilization . The creatures at this level of civilization have the ability to make full use of the resources of their planet.

Nicolah Kardashev

Take humans as an example. If our civilization level has reached the requirements of a first-level civilization, then this means that we can make full use of all resources on the earth, including the core, and even the moon, will become part of our development.

Unfortunately, according to scientists' determination, the current human civilization of is only 0.72 level , far from reaching the level of first-level civilization.

Secondary civilization is also called stellar civilization. , a creature in the secondary civilization, exceeds the limitations of its parent star and has the ability to develop broader galaxy resources.

If human civilization reaches this level, This means that we have the ability to manipulate the solar system, and the resources of the entire solar system can be used by us.

However, after reaching the secondary civilization, traditional energy conversion has become obsolete. requires a new device to develop and utilize stellar energy, including the sun.

This new device is called Dyson Ball . Dyson's ball can surround the star and then absorb the energy of the star for use by some civilization.

Functionally, the Dyson ball is like a solar panel, is just huge in size and absorbs not only sunlight, but all the energy of the star.

Level 3 civilization is also called galaxy civilization . When human civilization reaches this level, we will be able to use the entire Milky Way energy.

According to observations, the number of stars in the Milky Way is about 100 billion to 400 billion. So, when we enter the third-level civilization, humans will have the ability to use these hundreds of billions of stars, and the energy of and even the black hole can be used for us. What's even more terrifying is that in addition to being able to control all the energy of the stars and planets in the galaxy, the third-level civilization of can also utilize energy that exceeds the energy of the star energy by 10 billion times.

and, 10 billion times is just an average value. If the celestial body in which this civilization is located is huge, the energy available for utilization will be greater.

However, as of now, the possibility of a level 3 civilization is not very high.

Take humans as an example. Judging from our current development speed, it takes one or two hundred years to reach the first-level civilization, and one or two thousand years to reach the second-level civilization. But if you want to enter the third-level civilization, it will take at least one hundred thousand years.

can be seen that the third-level civilization is far beyond our cognition, not to mention the fourth-level civilization above the third-level civilization.

However, Kardashev only divided the three civilizations of levels. Level 4 civilization was expanded by later scientists on the basis of this third-level civilization.

How terrible is the fourth level civilization

In theory, the higher the level of civilization, the greater the demand for energy. In the fourth level civilization stage, 80% of the energy in the universe can be used by this civilization, including the largest number of dark matter in the universe.

dark matter is the cosmic matter that humans have not discovered yet. It occupies 80%-90% of the universe's space .

Level 4 civilization has the ability to subvert all matter, Even time and space cannot bind the level 4 civilization. It can use powerful energy to break the limitations of time and space.

However, although scientists divided the four civilizations of levels, they can be found that they don’t seem to like to mention the fourth-level civilization. Why is this?

In fact, there are three main reasons.

First, Level 4 civilization is too far away from humans. Even if technology advances rapidly, humans can only touch the edge of the second-level civilization at most in the future, and they cannot even see the shadow of the third-level civilization, let alone the fourth-level civilization.

Therefore, even when mentioning the fourth-level civilization, scientists can only make guesses, and these guesses cannot find the basis for reality.

second, there is a saying that goes, "The higher you climb, the worse you fall." Although the level 4 civilization of is so powerful, this is exactly what it is.

mentioned earlier that in the fourth-level civilization stage, the stars and planetary energy in the universe can no longer meet their requirements. At this time, they will use dark matter.

The main component of the universe is dark matter. Over-exploiting and utilizing dark matter is tantamount to hollowing out the universe. Once the content of dark matter in the universe is lower than a specific value, the universe may be out of order.

And no matter how powerful a civilization is, without a stable cosmic environment, what can it rely on to survive?

In addition, there will not be only one level 4 civilization, but for them, the universe resources are limited. Then, in order to obtain limited resources, these civilizations such as must be bound to compete and fight to the death.

However, there is actually no winner in this kind of battle. How much damage will two or more Level 4 civilizations fight to the universe? Without the universe, what's the use of no matter how much energy there is?

Third, although humans have been trying to find alien civilizations, psychologically, we are actually more inclined to accept civilizations with lower levels than humans.

If a higher level of civilization is discovered, it will not be a good thing for humans, Because in the face of higher level of civilization, we humans are small and incompetent as Ant .

Therefore, after realizing the insignificance of humanity, you will find that finding alien civilizations may mean the arrival of a bloody and violent war.

Therefore, some scientists do not agree with finding alien civilizations.

Conclusion

For humans, the most important thing at the moment is to be down-to-earth, develop your own civilization step by step, and strive to enter the ranks of advanced civilizations as soon as possible, so that you will not be easily controlled by other civilizations.
