While billions of people were watching demonstrations around various electronic devices, landers fixed the scenery, Mars rover slowly changed the scenery, and helicopters flew the scenery, the United Nations was also busy.

Before, everyone was following the live broadcast, and it took several hours to broadcast. Now it’s time to travel again, and everyone can finally go to the bathroom.

The same is true for most ordinary viewers who watch live broadcasts.

Now, scientists will pay attention to this situation. Most people only want to see the moment of alien contact in a few hours.

That's exciting.

After so many years of development on Earth, "science fiction culture" has formed a large system, and there are many considerations in contact with aliens alone.

For example, there is a very famous old science fiction movie that uses a contact category to make the movie name, which is "The Third Category of Contact".

According to the human-alien contact patterns summarized by people, they are divided into six categories.

The first is Class I contact, that is, distant sightings. Most of them are watching alien flying saucers fly rapidly through the sky, or seeing strange-shaped aliens from afar, and then the aliens disappear at the next moment.

Even if you can't see clearly and are uncertain, it's all about zero contact.

Currently, most of the international witness records related to aliens are like this.

Then there is the first type of contact, which is close-range sighting. This type of contact can roughly see the outlines of alien spacecraft and aliens.

Then there is the second type of contact, that is, a part of the human body touches something on an UFO or has traces left by eye-catching touches, which is the kind of aliens that cannot be seen.

Next is the third type of contact, which is the most relishable way of contact.

This method is to have direct contact with aliens and see the UFO clearly. Perhaps at this time, it can be confirmed that it is an alien spacecraft, especially the advanced humanoid living organisms on it, which are closer to the first type of contact.

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

You want to find evidence, sorry, no, we are just spiritual communication.

This contact pattern is also something that most researchers do not recognize.

After all, it's too mysterious.

But some people believe in this way of contact.

After all, the contactor is an alien. If it is not mysterious, then is it still called an alien?

Finally, the fifth type of contact is the contact between humans and alien civilizations using friendly information.

However, this is a classification divided by enthusiasts. Some people not only do not recognize the "fourth category contact", but also do not recognize this major category. For example, Dr. Heineke, an astronomer who served as an adviser to the Blue Book Project of the Merecon Air Force for twenty years.

He divided the contact events of those with aliens directly, saw clearly UFOs, and especially the contact events of advanced humanoid living beings into three categories.

The first type of contact is that UFOs do not affect the things around them, that is, there is no eyewitness record at all, and they really don’t know whether they come or not.

Just like the previous debate on "Whether there are aliens in the universe?", after all, no one has seen it before.

Of course, now, there is no need to argue about this debate, the aliens are already here.

The second type of contact refers to the flying objects affecting the surrounding things, but no physical UFOs or aliens are seen, such as the ground leaving regular burning traces, wheat field vicious circles, and abnormal radiation appears in places where radiation should not appear.

The third type of contact refers to the sight of alien creatures on the aircraft, including direct contact with them.

Later, some popular newspapers and science fiction described details such as some people being hijacked by alien creatures, and called it the fourth type of contact.

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

In fact, the movie "The Third Category of Contact" is not a simple third Category of Contact. It is neither category, but shows all types of contact.

The climax of this movie is the last part of the film, where humans use music to communicate with aliens, and then select civilized diplomatic ambassadors to formally establish a friendly communication channel between the two civilizations.

In a bunch of aliens invading the earth, it is a friendly and clear stream of aliens.

Of course, those are just science fiction works. The plot is like that, all stories were written in advance. Today, humans are going to come into contact with real aliens.

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

After all, in many movie plots, after encountering aliens, humans do not make quarantine, make plans, do not invite experts, do nothing, and go up on their own, and then...

Then hit GG.

Finally, he defeated the aliens with love, and the male and female protagonists kissed them in the sunset.

So in this case, first use unmanned equipment to explore the bottom and keep a buffer between the two parties. This is a better solution.

However, there are also many "hard flaws" that cannot be solved, which are hidden dangers in first contact.

Well, except for Tang Chao, everyone thinks so.

During this flight interval, Tang Chao left the mission center directly, left the live broadcast screen, and cut to the UN General Assembly site.

Compared to those who relax and go to find other things, and then call friends to watch the first human contact with aliens, the people at the United Nations General Assembly are more attentive and come back quickly after going to the toilet.

Now that Tang Chao is out of the live broadcast state, they need to communicate with Tang Chao quickly. After all, they will have to contact aliens next, so there cannot be any mistakes here.

"Mr. Tang, do you promise that there will be no problem?"

The representative of Meriken was very rude and said directly: "If it doesn't work, I think Meriken can replace the Navigator Company for this contact. After all, our deep space measurement and control network is the most comprehensive and can ensure the maximum smooth information."

Tang Chao sat in the office behind the command center, and there were several supervisors in the management and technology of the Navigator next to him. He didn't care what the representative of Merecon said, and directly replied: "Okay, if you solve the problem of ultra-long-distance communication delay and you will lead the mission, I have no objection."

"you……"

Representative Meriken was criticized for nothing. That thing is just a theory and no one can solve it. Why should they study it?

When other countries saw Meriken, they stopped talking, so naturally they stopped talking. Only Tianxia's representative old god was drinking tea.

Who made Star Pilot Company a company of Tianxia?

When Tang Chao saw that no one was talking, he continued: "No one should worry about the communication capabilities of this operation. Our leader has a complete communication satellite network. Although the radar antenna on the ground is not very good, because the unmanned detection spacecraft has an ultra-large communication antenna, the requirements for ground antennas are not high."

"The key problem now is the problem of communication delay. If there is an unexpected situation in our contact with aliens due to excessive communication delay, for example, they think we respond too slowly, think that it is neglecting them, and then forcefully face each other."

"After this happens, should we continue to explain and get friendly understanding? Or should we go to war with the other party directly?"

Tang Chao mentioned the difficulties, and representatives of the countries present also frowned because this was indeed a difficult problem.

It is hard for people living in the information age to imagine how late the information delayed by the ancient times, how many things would it take to delay when flying pigeons delivered letters, and how latency of the information would be?

Not to mention the ancient times, just a few decades ago, people generally used the postal system to send letters. Now, it is difficult for young people who can communicate video by pressing a button.

It turned out that people were just exploring Mars, and the communication delay had already caused an extremely low success rate. Now that we are encountering communication with aliens, it is difficult enough to just guess and crack the meaning of language. In addition, the communication delay is absolutely difficult!
