Don't answer, don't answer, don't answer-why are we looking for aliens?

Ye in the novel is high flyers, majoring in astrophysics. As soon as she graduated, she met that special era.

Society has given her and her father a lot of unfair treatment, and people around her have deceived and framed her.

Her bitter experience finally made her lose hope for human beings and society. Therefore, she believes that human beings can no longer solve their own problems, either being destroyed or relying on external forces.

So when she was working at the Red Shore base, she thought that she could summon the higher civilization in the universe through radio waves, hoping that aliens could come to the earth.

197 1 year, she secretly used the giant radio telescope in the base to emit radio waves to the sun, which was amplified by the sun and broadcast to the whole universe. Ye Wenjie didn't have much hope at that time, because no one had ever received a signal from aliens, and even she didn't have a definite answer about whether there were aliens in the universe.

Humans have also tried to find aliens, but they have found nothing for decades. So people want to know whether they can contact aliens actively. In the 1970s, the United States took the initiative to launch a spaceship with a business card to fly into outer space.

The business card is a gold foil with the image of a man and a woman painted on it, and a row of symbols depicts the positions of the sun and the nine planets in the solar system. It also marked the position of the earth, indicating that the spacecraft flew out from here.

Later 1977, the United States launched the probe Voyager-1, which can fly further. I brought a gold record with 1 15 pictures and more than 90 minutes of sound information, including the waves, wind, bird songs and all kinds of music on the earth, and recorded the greetings spoken by people on the earth in 55 languages.

These languages express the desire of human beings on earth to establish communication with alien civilizations.

After all, the speed of the spacecraft is not fast enough, so it is better to launch it directly with radio waves. Later, the world's largest radio telescope was used to send radio waves to the universe at a fixed point.

Of course, all these attempts have yielded no results.

In the three-body novel, Ye Wenjie sends a signal, which is just received by the three-body people in the three-body galaxy closest to the sun. Only four light years away, they immediately replied to the message. Eight years later, Ye Wenjie received a reply. There should be nothing more gratifying in the universe than this reply.

Ye Wenjie wants to summon aliens to save mankind, but in reality, the aliens we are looking for are obviously not for this reason. So why are we looking for aliens? What are the benefits of finding an alien civilization?

The significance of finding aliens can be said to be as great as it is.

It has far-reaching significance in science and technology, social politics and even philosophy.

For example, it can only prove the existence of alien civilization, even without any substantive connection, which can have a great impact on our human civilization, because in the vast universe, there is finally the existence of the other.

If we have contact with aliens, if aliens are willing to cooperate with humans and impart knowledge and wisdom to us, it may really help us get rid of the dilemma of nuclear war and environmental pollution.

On the other hand, if a country or regime on earth first gets in touch with aliens and forms an information monopoly, then the internal differences of earth civilization will widen sharply.

In this country, the economic and military influence is beyond everyone's imagination. He may reach the sky in one step, which may be a disaster for all mankind.

But the question is, what will happen if people don't intend to cooperate with us?

As described in the movie Independence Day, this possibility exists. We know that this is also a disaster.

In the novel, Ye's three-body man is not to help the earth people, but to immigrate to the earth.

The sociology of the universe and the theory of "dark forest" mentioned in the novel also explain to some extent why we should not expose ourselves. No wonder Mr Hawking always warns people not to contact with aliens.

But there must always be a civilization to stand up first, take this first step and truly explore the real universe. Since the invention of radio equipment, so many radio waves emitted in daily life have actually spread into the universe, and the position of the earth may have been exposed long ago.

No matter what the consequences are, it is impossible for human beings to resist their original desire to explore the universe. In the end, only time will tell us whether we can explore a new form of earth civilization through alien civilization in the future.
