The book "The Three-Body Problem" is a very famous science fiction novel in China, which has not only aroused the enthusiasm of many science fiction lovers in China, but also won the love of many readers overseas.
It shows Liu Cixin's cold cosmology and explores the relationship between cosmic civilization and human loneliness.
And Liu Cixin's coldness has also formed a cold way of thinking, which is exactly in line with this way of thinking is the law of the dark forest.
This law tells us that if life in the universe has a grand goal, it is to survive.
No one will let it go just because its survival will make it more difficult for others to survive, so the universe is like a dark forest, where the lives in it are trying to maintain their own survival, and at the same time trying to prevent other life from threatening them.
The communication between them is basically to destroy the other party before making sure that the other party is not threatening, so as to ensure their own safety.
But that makes it difficult to really cooperate, and even if two creatures are friendly to each other, it's likely that one of them is cheating on the other.
Although this law of the dark forest may seem pessimistic, it also has its practical significance.
Kepler 452-b is a planet with a very special environment, and from this point of view, it may be the birthplace of life in the universe, or it may be a planet that has developed advanced intelligent life.
Kepler-452-b is very slow relative to Earth, its year is only 11 days long, which means that its day is nearly 4 days long on Earth.
In this way, a year in Kepler 452-b is equivalent to more than three years on Earth, and a year is about three seasons, which may be the environment in which life can thrive.
And human beings, who are constantly exploring other planets for signs of life, are like always looking for a possible friend, and this obsession also comes from the loneliness of the strongest population on Earth.
At the same time, some people believe that the cosmic civilization in the book "The Three-Body Problem" may exist in the universe beyond the earth, but we have not yet discovered it.
1. Loneliness.
Human exploration of extraterrestrial life can be said to be a kind of curiosity about the universe and a response to the growing loneliness of human beings.
Human beings are the strongest species on the earth, they have almost nothing on the earth that can threaten their survival, and human beings have also created their own civilization with their own hands and become the most powerful race on the earth.
But it is precisely because of this that human beings on the earth gradually feel the existence of self-loneliness.
On earth, no human being can match human intelligence with human beings, and it is precisely because of this that there is hardly anyone with whom human beings can talk to each other, and no one who can understand themselves.
As a result, human beings began to look outwardly and wanted to find a partner in the universe who could understand themselves.
On the earth, the exchanges between human beings are also relatively complicated, and the exchanges between them are either for the purpose of expanding their sphere of influence, or purely for survival, etc., and various purposes make the exchanges between human beings quite complicated.
In the universe, other populations also have their own goals, and even peace-loving populations may be understood by humans as having ulterior motives, thus triggering a cosmic war.
It is precisely because of the complexity of this communication that human exploration of the universe has become more difficult.
And if there really is a population in the universe that is stronger than humans, then humans, as the king of the population on the earth, are likely to be treated as a threat by the other party, which will cause a cosmic catastrophe.
In "The Three-Body Problem", many human beings died because of this, which also made human beings cautious in their exploration of extraterrestrial life, but it also could not stop human curiosity about the universe.
It is as if human beings are searching for themselves while exploring the universe, and they want to find an existence in the universe that can understand themselves and fill the gap in their hearts.
Human beings are actually a species full of loneliness, and different people will experience loneliness differently at different times.
But, in general, the richer a person is, the more lonely they feel.
People who live at the bottom of society, because of the pressure of life, often spend every day in a busy way, and they rarely have time to feel lonely.
But it is easy for people to ignore a problem, that is, when the rich are busy, they are often lonely, lonely, and they also feel lonely in the process of comparison.
In those who are richer than themselves, they see their own insignificance, but also their loneliness.
By exploring the external world, it is also the process of human beings understanding themselves, and only by observing the external world can human beings better understand themselves.
2. Voyager probe.
Human exploration of extraterrestrial life has never stopped, and human exploration of the universe is also constantly deepening.
In 1960, the United States set up a team of probes called "Voyagers", and their goal was to let the probes fly out of the solar system, into the stars, and see the world beyond the solar system.
And in 1977, the first Voyager probe set off for Saturn, which flew a long distance and finally reached Saturn in 1980.
However, in 1986, a second Voyager probe set off, targeting Uranus and Neptune, but after flying by Uranus, it took longer to fly by Neptune due to the relationship between Neptune and Uranus, so it only reached Neptune in 1989.
After that, mankind began to welcome the new century, and the mission of the Voyager probes was completed, and they were decommissioned, but their contribution to mankind was very huge, so they were also called "children of space" by mankind.
The exploration of extraterrestrial life has never stopped, and mankind has begun to look for the next probe, the goal of which is to leave the solar system and go to the starry sky.
In 2006, the new-age Voyager probe was finally launched, named "New Horizons", and the goal of this probe was to fly to Pluto, but it did not disappoint mankind and successfully completed the mission.
However, New Horizons' mission is not over yet, it continues to move forward, and humanity is waiting for news of it.
And in 2015, New Horizons finally flew out of the solar system and began to receive the information that humans hoped it could gather, and at the same time began to explore the starry sky.
In December 2015, New Vision sent a message to mankind that it had discovered a planet in the starry sky, which was named "Kepler 452-b" by humans.
Kepler-452-b is a planet 1,400 light-years away from Earth, which is a very long distance from Earth, and even at the speed of light, it would take 1,400 years to get there.
However, from the perspective of interstellar probes, it is not far at all, and the interstellar probes launched from the Earth have been all the way forward, and finally come to Kepler-452-B.
Since then, Kepler-452-b has also entered the field of human vision, and at the same time has become the most famous probe in human history, after all, it discovered Kepler-452-b.
Kepler-452-b's orbit is slightly farther than the Earth's, and its parent planet, Kepler 452, is more than twice as far away as the Earth's distance from the Sun, making it a long year.
For about 450 days, due to the distance between Kepler 452-b and its parent star, its temperature will not be as low as that of Mars, but will be in the temperature range suitable for life.
Therefore, it has been suggested that Kepler 452-b is most likely the second Earth that mankind has been seeking, a place where humans can live in the future, and a place where humans can seek signs of extraterrestrial life.
3. Life in the universe.
The discovery of Kepler 452-b has triggered human thinking about the universality and survival possibility of life in the universe, and has also provided more imagination space for future exploration of extraterrestrial life.
On Earth, the only life forms that humans can find are microorganisms and plants, but not animals, which also makes the exploration of extraterrestrial life even more mysterious.
At the same time, it also makes human conjecture about extraterrestrial life more obscure, human beings always use themselves as a standard to imagine life forms on other planets, but in fact, life forms in the universe may be completely different from life forms on Earth.
Human science and technology for the exploration of the universe is also very limited, so far, human beings have not been able to fly out of the solar system, so for the life on Kepler 452-b, human beings have not yet been able to detect.
However, this does not become an excuse for human beings to give up, and it is precisely because of human curiosity about the unknown that human beings continue to explore and progress.
Only when human beings continue to develop their own science and technology can it be possible to have a deeper understanding of the universe and whether there are other life forms in the universe.
Life in the universe may be the same as life on earth, or it may be completely different from life on earth, and human exploration of the universe is also a process of constantly searching for answers.
Only human beings can find the answer through continuous exploration, otherwise they can only keep wandering in speculation.
At the same time, human exploration of extraterrestrial life also reflects human beings' thinking about their own status and the meaning of life, and human exploration of extraterrestrial life is also a process in which human beings are seeking the meaning of their own existence.
The discovery of Kepler 452-b has made human beings cherish the earth and think more deeply about their own living environment, and people have gradually realized the importance of the earth and gradually begun to pay attention to environmental protection and sustainable development.
epilogue
The discovery of Kepler 452-b is a great progress for mankind, and it is also a spur to mankind, hoping that mankind can continue to make progress and exploration, so that mankind can have a deeper understanding of the universe.
Only by constantly developing our own science and technology can we let human beings have a deeper understanding of the universe and give them more room for imagination.
