Chapter 1194

Human beings are proud of themselves. In the 4.6 billion years since the birth of the earth, countless lives have appeared. Only human beings have finally evolved into intelligent life and developed to the present scientific and technological civilization.

When you look up at the sky, you feel that the earth is so small. Many people think that the universe is so big. Is the earth the only civilization? How many civilizations like the earth are there in the universe?

See the vast universe, once the confidence and pride are gone. From the perspective of the universe, the earth is too small. And human technology can not even go out of a small solar system, do we still feel very powerful?

As for the level of human civilization, as early as last century, the Soviet scientist Nikolai Kardashev proposed the famous "kardashov index" standard for the classification of cosmic civilization. He divided the level of civilization according to the level of civilization and energy technology.

First class civilization, which is the master of planetary energy, means that they can dominate the sum of all the energy on their planet.

According to this standard, the current level of human civilization can only be roughly divided into 0.8 level. Because humans can use most of the earth's energy, but the resources in some places are still not available.

Even if the infinite gravitation group has started to use higher level nuclear fusion reactors to provide energy on a large scale, but this does not mean that human beings can really make full use of all the energy of the whole earth.

Secondary civilization can make use of all the energy of the star system. For example, the famous theory of using the energy of the central star mentioned in the famous daisenball theory can be used by secondary civilization.

In recent years, the "space energy factory" project of the infinite gravity group has begun to involve the study of this civilization level.

However, even if the infinite gravitation group is 120000 kilometers away from the earth, it has successfully built two super solar power stations with a total area of 300000 square meters, and has been able to deliver a lot of energy to the moon, ensuring that the two large bases on the moon can keep normal operation during the half month long lunar night, and even can give The earth transports a certain amount of energy.

However, such utilization efficiency is not particularly high. It is still a hundred thousand miles away from being able to fully use the energy of the whole sun. There are few problems to be solved.

Kuafu said that the accumulation of details also has such factors. Without enough time for technology accumulation, it is impossible to achieve a breakthrough in civilization level, even if it is Lei Tiantang.

Third level civilizations can use the energy of a galaxy. The sign is that this level of civilization has been able to achieve the speed of light flight, or super light travel, which is also the technology Lei Tiantang most wants to master, but they have no clue from now on. This can show how difficult such technology is.

As for the fourth level civilization, it can be called God level civilization. Level 4 civilization can basically use the energy of the whole universe.

Of course, this is a relatively rough division. If you refine it a little, the four levels can be further refined into 12 levels. Even so, the current level of human technology has not broken through level 1 in this level.

0. Our earth civilization (zero level civilization): it is equivalent to 0.8 first-class civilizations. There are primary stages of space station technology, space technology, and various physical theories. Mankind has been able to preliminarily look into space.

1. First class Civilization: can only migrate between planetary systems. And being able to transform other planets, such as the moon and Mars, has not yet been able to colonize between star systems.

Even with the participation of the infinite gravitation group, the development of the moon and Mars is still in the initial stage, and large-scale transformation and immigration are still very early.

So Kuafu's cold water on Lei Tiantang is not a problem, because according to this standard, it is obviously impossible to say that human beings have reached the first level civilization. Human beings are still the poor zero level civilization, but now they are qualified to break through to the first level civilization. As for the second level civilization, you don't have to think about it.

2. Second class Civilization: able to immigrate between neighboring star systems, with an activity range of about 10 light-years. According to this standard, even the unmanned spaceship launched by Lei Tiantang has not yet separated from the solar system!

There is no place for the probe to reach, let alone immigration and other things. Even if Lei Tiantang has completed the design and manufacture of the earth spacecraft, there is no guarantee that we can quickly explore the solar system surrounding the solar system, let alone the thing that human beings can achieve level 2 civilization.

3. Third level civilization: be able to carry out basic navigation in Hanoi. The Galactic class can make basic voyages wherever it is found. However, due to the long sailing time, there are communication restrictions. The range of activity is about 100 light-years.

It's not that we can't go further, but there's no need to go there. Even if we find something good, it's not worth the loss if we want to transport it back.4. Level 4 civilization: it can initially use natural wormholes for river navigation. This problem is also the most perplexing problem for Lei Tiantang. We should know that the solar system is about 22000 light-years away from the small black hole itself!

Although they are all in the Milky way, even if the spacecraft can fly at the speed of light or even fly faster than light, it is impossible to get there in the lifetime from the solar system. Even if the Spacecraft flies at 10 times the speed of light, it will take about 2200 years to arrive!

So the only thing they can do is to find natural wormholes or weak spots in space, and see if they can get to their destination quickly by jumping, otherwise they will have to wait in the solar system.

If he had been away from the earth for more than 2000 years, even if he had lived so long, he would have successfully devoured the small black hole itself, and immediately returned to the earth. Then whether the earth will exist or not will still be a problem.

Even if the earth is lucky to still exist, so long the vicissitudes of life are enough to make everything familiar to Lei Tiantang disappear in the long river of history. What is the significance of his busy life to devour the small black hole itself?
