According to the level of cosmic civilization, the earth can only be considered as a civilization of .7, and the top civilization is unimaginable.

The concept of classifying cosmic civilization was first put forward in 1964 by Kardashev, an astronomer of the former Soviet Union, and it is called the "Kardashev" index, also known as the civilization development level index. Kardashev divided the cosmic civilization into three types according to its scale. Generally speaking, the type I civilization is the mother star civilization, the type II planetary system civilization and the type III stellar system civilization.

Although our earth is not even a type I civilization now, it may be impossible to imagine what a level III civilization really looks like, but advanced civilization is described in many literary works or film and television works. For example, the story setting of Star Wars is that we have mastered the advanced civilization of Interstellar. Although this film was made in the 196s, we have to say that the consciousness and thoughts of the film are really advanced. Another example is the movie Interstellar, in which there is the imagination of multi-dimensional space.

this level of civilization can make use of the energy of the planet itself (including its own energy and the energy given by the stars in the star system). The utilization of the earth by human beings has not reached the level of full utilization. For example, our development is limited by the limitations of various energy sources, but it has destroyed a lot of the earth.

If the earth civilization is to reach Type I, then the most likely way is to master controlled nuclear fusion (which was explained in detail in the last article). Since all the energy we can use on the earth comes from the sun in the final analysis, mastering controlled nuclear fusion technology is equivalent to having inexhaustible energy. The number of .7 civilization that the earth has reached now is not the exact level, but is estimated according to the formula.

China has a group of outstanding theoretical masters in the field of controlled nuclear fusion, plus China's attention to this technology (which has been studied for more than half a century since 1956), and China's Inner Mongolia is the world's first rare earth resource, which has now become the world's first group. As early as 212, it broke through many technical problems and was far ahead of the world. Perhaps China will take the lead in breaking through controlled nuclear fusion's technology and leading all mankind to nuclear energy civilization.

"Type II civilization" means that we can make use of the energy of stars in the solar system, that is, our activities have reached the whole solar system and neighboring galaxies, and we can immigrate to other planets in the solar system. Although we haven't reached type I civilization yet, we have actually started our journey to type II civilization since the first landing on the moon.

but unfortunately, our present ability has not reached any other planet except the moon. Moreover, the exploration of the moon only stops at inserting the national flag, and it is still difficult to establish a base on the moon. In the process of moving towards type II civilization, we will gradually establish space stations on the marginal planets of the solar system. After reaching type II civilization, perhaps we no longer live on the earth and immigrated to other planets; Or we live in a space city.

type ⅲ civilization can use the power of the whole galaxy, in other words, it can move freely in the galaxy. In my opinion, this is close to the level of God. Perhaps at that time, black holes are no longer mysterious, and can be used by us. To some extent, they have mastered time and space, can travel between stars, and can travel to the past or the future.

This is beyond human imagination. The farthest distance between the two ends of a galaxy ranges from hundreds of thousands of light years to hundreds of millions of light years. What a concept it will be to be able to travel in the vast galaxy!

there must be a more advanced civilization besides the third-level civilization. Because there are countless galaxies as big as the Milky Way outside the Milky Way, there are 1 billion galaxies in the universe that can be measured by human beings at present, covering the whole universe, so there is a civilization that can cross the Milky Way.

maybe they can exist in any form they want, even in consciousness, and they don't have to be confined to fragile bodies. In addition, they can use most of the rules in the universe to transform the world. The meaning and value of their existence can't be guessed, and it's difficult to describe their purpose, because only a few things are meaningful to them.

tsiolkovsky said, "The earth is the cradle of human beings, but human beings cannot be bound in the cradle forever." You know, our goal is the sea of stars.
