Life is the most amazing and complicated thing that has appeared since the birth of the universe. Nothing can compare to the greatness of life, but even such a great life is not omnipotent. When faced with various natural disasters, it will also appear very small.
The earth has a long life history of 4 billion years. In such a long time, there have been tens of millions of life types, but these life types have not been able to continue forever. Rather, in various ecological disasters, the constant extinction disappeared. Even 65 million years ago, the dinosaur, who had dominated the earth for 160 million years, was extinct because of the impact of an asteroid.
After the end of the dinosaur age, mammals began to rise, and humans were born millions of years ago. Human beings are different from other creatures. We are intelligent life, relying on wisdom to dominate the earth and become the creature at the top of the food chain.
Although human beings are intelligent beings, we deeply know that nature is still something we need to fear. When human beings face the disasters of nature, they still have no good means to deal with it, but as human beings enter the age of technology, with the help of technology, we finally have the courage to face nature directly. With the confidence and hope to overcome nature.
The rapid development of science and technology allowed mankind to quickly walk out of the earth and see the vast universe. Only when we have truly stepped out of the earth can we know how small the earth is, and at this time, mankind has a greater goal of hard work, that is, the stars and the sea, becoming the overlord of the universe.
The dream of becoming the overlord of the universe, I believe that every human being is very much looking forward to it. But when we truly see the vastness of the universe, we have to think about the question, that is, does intelligent life like human beings exist in the universe?
From the perspective of the vastness of the universe and the age of the universe, we have to admit the fact that the probability of existence of alien civilization is basically 100%. If alien civilizations exist, the strengths of civilizations are naturally different due to the time of birth and development. Some may be weaker than humans, and some may be much stronger than humans.
So how is the strength of cosmic civilization divided? In the early 1960s, the former Soviet Union cosmologist Kardashov assumed a three-level model of cosmic civilization based on the level and total amount of energy that civilization can master and use. Later, some scientists extended this three-level model to seven levels, which means that the strength of the cosmic civilization can be divided into seven levels.
The first-level cosmic civilization can be called planetary civilization, which means it can use all the energy and resources on the parent planet. We know that the first place of any civilization is on the planet, and as a life planet, there must be a lot of resources and energy.
These resources and energy are the key to the development of a smart civilization towards the stars. As long as the resources on the planet can be fully utilized, then this civilization can be upgraded to a first-class civilization step by step. When we can fully utilize the resources on the home planet, we will truly become the overlord of the earth, not only dominating the biological world, but also above nature, truly mastering nature, and letting it serve us.
If human beings reach this stage, then we are the gods of the earth and possess the supreme power on the earth. Nature does not have to refute human beings, but can only serve at the request of human beings. Unlike now, nature often goes crazy by itself. It has brought damage and loss to ecology and human beings.
The secondary cosmic civilization is a stellar civilization, which means that it can use all the resources of the entire parent star system. Let’s take the solar system as an example. It is the star system where humans live, and the solar system has a very wide range. If the Oort Cloud is included, the diameter reaches 2 light-years.
With such a wide range, there is naturally no way for human beings to exploit resources. But when we become a second-class civilization, the solar system is our back garden. We can establish mining bases on various planets and collect the resources of each planet for our use.
At this time, humans also have the ability to freely shuttle through the solar system, and can initially walk out of the solar system and explore the nearby starry sky. In addition to these planetary resources, the most important resource of the solar system is the stellar sun. Using the energy of stars to serve us has always been the goal of scientists’ continuous exploration.
After becoming a second-class civilization, we have the technology to initially apply solar energy. Super man-made buildings that absorb stellar energy such as the Dyson ball will also be manufactured. Of course, because of the construction of a full version of the Dyson ball, the resources needed are really there. A huge collection of the resources of all planets in the solar system may not be complete. Therefore, in the second stage of civilization, we can only build a simple version of Dyson Sphere to meet human development needs.
The third-level civilization is a galaxy civilization, which means that the resources of the entire galaxy can be used. Taking humans as an example refers to the resources of the entire galaxy. The diameter of the Milky Way has reached 100,000 light-years. With such a vast space, it is conceivable that it is difficult to mine and apply resources. The most important thing is the ability to fly faster than light.
If there is no such speed as the speed of light, we will not be able to travel across the Milky Way, and naturally we will not be able to use the resources of the entire galaxy. Therefore, after reaching the third-level civilization stage, he has initially mastered some space jumping techniques, and can initially achieve super-light speed shuttles. You can easily shuttle between various star systems to mine resources.
After reaching the third level of civilization, since resources are no longer a problem, a full version of the Dyson sphere can be built at this time to truly surround the stars to absorb energy. The third-level civilization can be called an intermediate-level cosmic civilization, and it is already considered a relatively powerful strength in the cosmic civilization.
The fourth-level civilization can also be called an interstellar civilization, which can shuttle between different galaxies. Although the third-level civilization has mastered the preliminary space jumping technology, there is still no way to shuttle between the big galaxies. After the fourth-level civilization, the space technology is further advanced and can jump farther distances. You can go to other large galaxies to explore and mine resources, completely free from the constraints of the Milky Way.
Level 5 civilization is a dimensional civilization. After reaching this stage, civilization has begun to break away from primary space applications and rise to dimensionality. The conjectures about the multidimensional universe have now been proposed by scientists, but if you want to truly understand what dimensions are and be able to carry out primary applications, you may need to reach the fifth-level cosmic civilization.
After mastering the preliminary dimensional technology, we can break through time and space and enter other dimensional spaces. After mastering the ability to break time and space, you also have the ability to create wormholes, and you can go farther in the three-dimensional universe and reach all corners of the universe. There is nothing in this universe that can restrain us.
The sixth-level cosmic civilization is a truly advanced civilization. They have the ability to break the barriers of the universe and can run out of the universe and go to other parallel universes. Perhaps when a civilization reaches the sixth level of civilization, they will leave the universe and go to the big world outside the universe. For an advanced civilization, our universe is only a small space.
The seventh-level cosmic civilization is the ultimate civilization, which can also be called a god-level civilization. They have mastered all the mysteries of the universe, and are not restricted by the rules of the universe. Time and space are the ultimate goals they want to explore. For a seventh-level civilization, the universe can travel at will, can freely change the rules of the universe, and even be able to Create a new universe out.
The above-mentioned civilizations at all levels believe that each of us is very hopeful, especially the seventh-level civilization is so strong that it is invincible. So what level of civilization does human beings belong to under this classification standard? If a careful friend may already know the answer, it is that mankind is not even a first-class civilization.
We have not yet been able to use all the resources on the earth. We have not yet defeated nature and truly become the supreme ruler of the earth. According to the research of scientists, human beings can only be regarded as level 0.7 civilization at most. Although it is only level 0.3 away from level 1, it may take at least hundreds of years to reach it.
And to become a higher civilization or even the ultimate seventh-level civilization, it will take an extremely long time, even from the birth of the universe to the present, whether there is a civilization above the sixth level is still unknown. According to the classification standards of civilization levels, the sixth-level civilization has been able to travel around the universe easily and freely, and everything in the universe is basically well understood.
If civilizations above level 6 really exist, then the existence of the earth and humans may have been known for a long time, and they may come into contact with humans. Even if there is no direct contact, humans may know their existence, but the reality is that we have not found any traces of the existence of alien civilizations. In this case, either the alien civilization does not exist, or the level of the alien civilization is not high, and there is still no way to arbitrarily shuttle through the galaxy and across the universe.
