With the continuous understanding of the universe by human beings, people generally believe that there is not only human civilization in the universe, and it is true that the universe is vast and unimaginable, and there are so many galaxies, it is impossible to have only lonely human beings.
In the last century, some scientists have classified the intelligent civilization of the universe, and the current scientific and technological level of our human civilization is only about 0Level 73 or so,So with the current development progress, when will human beings enter the first-level civilization?
The proposer of the hierarchy of intelligent civilization is Nikolai Kardashev, an astronomer from the Soviet Union, who roughly divides the cosmic civilization into three levels, namely the first-level civilization, the second-level civilization and the ** civilization.
The so-called first-level civilization is also called planetary civilization, that is, the civilization is the master of the planet where it is located, and it can control and use all the energy resources on the entire planet for its own use. For example, dealing with various disasters from the planet.
The second-level civilization is also the stellar civilization, which has entered a higher level, which can use and control all the energy of the entire planetary system, and in this kind of civilization has been able to obtain stellar energy, such as building Dyson spheres, and can travel around the major planets at will to develop resources, and deal with all disasters in the planetary system.
The ** civilization is the galaxy civilization, which has reached a point that we can hardly imagine, it can use and control all the resources of the entire galaxy, that is, it can travel between stars at will, and develop resources, this civilization has at least mastered wormholes or other ways of traveling.
According to the classification of Kardashev civilization, the level of energy that human beings can currently master and use is only about 0Around level 73, scientists guess that with the current trend of scientific and technological development, it will take at least 200 years for human beings to reach a first-level civilization, and it is a conservative estimate. Because the leap from 0-1 is a big chasm.
We know that the main application energy of human beings today is chemical energy, and to cross to the first level of civilization at least need to master efficient energy conversion technology, at least controllable nuclear fusion technology, at this time human beings are no longer troubled by the shortage of resources.
In addition to the above, human beings also need to be able to deal with various threats from the earth itself and outer space, such as preventing the impact of asteroids, extreme natural disasters on the earth itself, etc., that is to say, when entering the first-level civilization, human beings have been able to fully deal with threats such as super ** and volcanic eruptions, and at the same time, they can also control and control the earth's climate change.
In addition, the lifespan of human beings will be greatly extended, and viruses and diseases have been completely conquered by humans. And rising to space, human beings can even establish a base on the moon to develop lunar resources, which means that human beings will already be the absolute rulers of the earth, and nothing on the earth will pose a threat to human beings!
However, it is difficult to say when human beings will be able to enter the first-level civilization, after all, the breakthrough of science and technology is not just a matter of paper, but the accumulation of time, maybe in a hundred years, or thousands of years later.
