While billions of people are watching demonstrations around various electronic devices, landers fixing scenery, Mars rover slowly changing scenery, and helicopter flying scenery, the United Nations is also busy.

Before, everyone was paying attention to the live broadcast, which was just a few hours, but now it's finally time to rush again, and everyone can finally go to the bathroom.

The same is true for most of the regular viewers who watch the live stream.

Now this situation is what scientists will pay attention to, and the average person only wants to see the moment of alien contact a few hours later.

That's what excites me.

After so many years of development on the earth, "science fiction culture" has formed a large system, and there is a lot of attention paid to contact with aliens alone.

For example, there is a very famous old science fiction movie that directly uses a contact classification as the movie title, that is, "The Third Kind of Contact".

They are divided into six categories based on the patterns of human-extraterrestrial contact that people have generalized.

The first is zero contact, that is, distant sightings, most of which are watching alien flying saucers fly rapidly through the sky, or seeing strange aliens from afar, and then the next moment the aliens disappear.

Even indistinct and uncertain are the same, they are all zero-class contact.

Most of the current international sightings related to aliens are like this.

After that, there is the first type of contact, which is a close-up witness, which can roughly see the silhouette of the alien ship and the alien.

Then there is the second type of contact, that is, a part of the human body touching something on a UFO or witnessing the traces left by the impact, the kind that does not see aliens.

Then there is the third type of contact, which is the most talked-about.

In this way, people have direct contact with aliens and see UFOs clearly, perhaps at this time, it can be determined that it is an alien spaceship, especially after seeing the humanoid advanced life forms on board, which are closer than the first type of contact.

As for the fourth type of contact, it is mysterious, it is to communicate with aliens through telepathy, which is the case of "I have been friends with aliens for a long time".

You're going to say look for evidence, sorry, no, we're just communicating with each other.

This pattern of exposure is also unrecognized by most researchers.

After all, it's too mysterious.

But there are also those who are convinced of this type of contact.

After all, the contact is an alien, if it's not mysterious, is it still called an alien?

Finally, there is the fifth type of contact, in which humans communicate with extraterrestrial civilizations with friendly messages.

However, this is a classification of enthusiasts, and some people not only do not recognize the "fourth type of contact", but also do not recognize this large category, such as Dr. Heineke, an astronomer who served as an advisor to the Blue Book Project of the Air Force Department for two decades.

He divided those who had direct contact with aliens and saw UFOs, especially humanoid advanced life forms, into three categories.

The first type of contact is that the UFO does not affect the surrounding things, that is, there is no sighting record at all, and it is really unknown if it has not come.

It's the same as the previous debate about whether there are aliens in the universe, after all, no one has ever seen it.

Now, of course, there is no need to argue with this debate, the aliens have already arrived.

The second type of contact is when the flying object affects the surrounding things, but no physical UFO or alien is seen, such as the ground leaving regular burning marks, crop circles, abnormal radiation in places where it should not be, etc.

The third type of contact refers to the sighting of extraterrestrial creatures on that vehicle, including direct contact with them.

Later, there were popular newspapers and science fiction that described details such as the hijacking of some people by extraterrestrial creatures, which was called the fourth type of contact. 2018

However, in serious scientific writings, these phenomena are generally still included in the third category of exposure.

In fact, the movie "The Third Kind of Contact" is not a simple third type of contact, neither of the two classifications, but shows all the types of contact.

The climax of the film is the final part of the film, where humans use music to communicate with aliens, and then the ambassador of civilization diplomacy is also elected to officially establish a friendly communication channel between the two civilizations.

In a bunch of films about aliens invading the earth, it can be regarded as a clear stream of alien friendliness.

Of course, those are just science fiction works, and the plot is a story written in advance, and today, humanity is about to come into contact with real aliens.

Although it is only through an unmanned probe and then contact on another planet, this may be a better solution for human civilization.

After all, in many movie plots, after humans encounter aliens, they don't do isolation, don't make plans, don't invite experts, etc., don't do anything, just go up by themselves, and then ......

Then hit GG.

In the end, the aliens were defeated with love, and the hero and heroine kissed in the sunset.

So in this case, it is a better plan to use unmanned equipment to probe the bottom and keep a buffer zone between the two sides.

However, there are also many "hard wounds" that cannot be solved, and they are hidden dangers in the first contact.

Well, except for Tang Chao, everyone thinks so.

In this kind of flight interval, Tang Chao left the mission center directly, left the live broadcast screen, and fully cut to the scene of the United Nations General Assembly.

Rather than people who relax and go to find other things and then call friends and wait to see the first human contact with aliens, the people here at the United Nations General Assembly are still a little more attentive and hurry back after going to the bathroom.

Now that Tang Chao is out of the live broadcast state, they need to communicate with Tang Chao quickly, after all, they are going to contact with aliens next, and there can be no mistakes here.

"Mr. Tang, do you guarantee that there will be no problems over there?"

The representative of Merrican was very polite and said directly: "If it doesn't work, I think Merrican can replace the Navigator company to carry out this contact, after all, our deep space TT&C network is the most comprehensive, which can ensure the maximum smoothness of information." ”

Tang Chao sat in the office behind the command center, and there were several directors of the navigator management and technology next to him, and he didn't care what the representative of Merrican said, and directly said: "Okay, if you solve the problem of ultra-long-distance communication delay, you take the lead in the task, I don't have any opinion." ”

"You ......"

Representative Merrican was stunned and had nothing to say, that thing was just a theory, no one could solve it, why should they be allowed to study it.

When the other countries saw that Merriken didn't speak, they naturally stopped talking, only the old god of Tianxia's representative was drinking tea.

Who made the Star Navigator company Tianxia's company?

And Tang Chao saw that no one spoke, so he continued: "Everyone doesn't have to worry about the communication ability of this operation, our navigator has a complete communication satellite network, although the radar antenna on the ground is not very good, but because the unmanned exploration spacecraft has a super-large communication antenna, the requirements for the ground antenna are not high." ”

"The key problem now is the problem of communication delay, if there is an unexpected situation in our contact with aliens because of the long communication delay, for example, they think that we are too slow to reply, think that we are snubbing them, and then use force against them."

"When this happens, do we want to continue to explain and then get an amicable understanding? Or is it a direct war with the other side? ”

Tang Chao said the difficulty, and the representatives of the countries present also frowned, because this is indeed a difficult problem.

It is difficult for people living in the information age to imagine the degree of delay in the information of the ancient fast horses, flying pigeons, and Yang Fan's letters.

Not to mention the ancient times, let's just say that a few decades ago, people still used the postal system to send letters, and now it is difficult for young people to accept video communication at the touch of a button.

Originally, people were only exploring Mars, and the communication delay had caused a very low success rate, but now when it comes to communicating with aliens, it is difficult enough to guess each other and decipher the meaning of the language, plus the communication delay, it is absolutely hellish difficulty!
