What are the levels of cosmic civilization?

There are many ways to classify the civilization of the universe. This is an open topic and there is no absolute conclusion at present.

At present, the mainstream classification method is: Kardashev grade.

This method has three levels:

The first level: you can control the planet energy and the surrounding satellite energy. In other words, fully grasp the use of planetary energy. Take the earth as an example, that is, all the energy on the earth and the moon can be used.

The second level: you can use the energy of the whole star. Take the earth as an example, we can use the energy of the whole solar system, which is the development of solar energy described in science fiction.

The third level: you can use galaxy energy. The galaxy here is not a star system, not a small galaxy like the solar system, but a galaxy as big as the Milky Way. Take the earth as an example, that is, we can use the energy of the whole galaxy.

According to this method, at present, human beings on the earth can't even reach the first level.

However, Kardashev rank is not unique, and it is definitely not the only way to measure the rank of the universe.

Because, the development of cosmic civilization is varied. The earth civilization is based on energy, so the Kardashev grade is more in line with the requirements.

Assuming that a civilization develops in a way of thinking and consciousness, this classification method is meaningless.

Moreover, if a civilization is developed through virtualization technology, then this division is also invalid.

For example, in the hard science fiction works in Europe and America, it was written that humans came to a planet and found nothing on it. But later I learned that the original civilization was developed by virtual technology. They have uploaded everyone's thoughts to the virtual world, so the physical world has been completely abandoned.

Of course, there are other mainstream ways to classify the universe.

In addition, there is another method:

Level one, you can leave this planet. Take the earth as an example, that is, you can fly away from the earth and go to other planets.

Level 2: You can leave the star system. Take the earth as an example, it can fly out of the solar system.

Level 3: You can leave the Milky Way.

The fourth level: you can cross between galaxies through the transition technology.

Level 5: You can reach every corner of the universe.

Level 6: Can fly out of the universe.

Level 7: You can travel between different universes.

This is graded according to leap's shooting range technology. According to this method, the earth can't even reach the first level at present.

Of course, there are other ways to divide it.

For example, depending on speed:

Level 1: Reach the speed of light.

The second level: beyond the speed of light.

The third level: beyond the speed of the whole universe. Which means flying out of the universe.

According to this method, if you reach the first level, you will surpass the speed of light and cross the universe. Humans have not even reached the first level.

Of course, these are all classified according to technology. There are still some points that are not divided according to science and technology, but according to thinking consciousness.

For example; According to the division of consciousness:

The first level: communicate with other people on the planet with consciousness.

The second level: communicate with people on different planets with consciousness.

The third level: communicate with the life of different galaxies with consciousness.

The fourth level: communicate with life in different universes with consciousness.
