At first I didn’t think so, but later Tang Chao felt that it was such an unwise choice for him to attend this meeting.

Because of unknown probes, or directly talking about alien probes, the high-level meeting invited experts from many aspects and made many assumptions that ranged to the edge of the universe. The most common assumption is how humans should deal with it after the real aliens arrive.

Or, how should Tianxia deal with it?

Experts divided the hypothetical extraterrestrial civilizations into nine categories, namely orderly kindness, neutral kindness, chaotic kindness, orderly neutrality, complete neutrality, chaotic neutrality, orderly evil, neutral evil and chaotic evil.

Tang Chao was confused after hearing this.

Good guy, are you playing with the nine-grid grid of the camp?

But if you think about it carefully, it is actually almost the same, it means that.

But this time they were destined to fight wits and courage with the air, because they thought of almost all the situations, but they didn't expect that the aliens who came might be a group of stupid people.

But generally no one would think that aliens are either Titan Hanhan or Titan Hanhan.

After all, it can develop to the level of civilization that can launch detectors into the solar system, and it cannot be foolish than humans in the solar system... right?

Tang Chao can tell everyone the truth: Yes.

Of course, there is still a difference between stupid and stupid.

"Xiao Tang, what do you think?"

“Ah, some.”

“What are there?”

"Uh, what were you asking just now?" Tang Chao looked at the old scientist sitting next to him embarrassedly.

"I mean the proposal just now, we must be prepared for battle and cannot sit and wait for death." The old scientist said again.

Tang Chao understood that he was indeed talking about defense and counterattack just now.

Tianxia is very familiar with this matter. It has been doing this since its founding.

The issue of safety must not be handed over to others' hands, nor should it put expectations on other people's good and evil.

Even if humans have limited abilities, they cannot completely open the door and allow aliens to enter and exit.

The discussion in the conference room just now talked about the matter of laying out weapons in space.

Although the Outer Space Treaty clearly stated that it restricts the militarization of space, the Meriken has blatantly established a space force and even converted two second-level space shuttles into space fighters. This is no longer taking the Outer Space Treaty seriously.

If Meriken can do that, Tianxia can do it naturally, but before the aliens are sure to arrive, the United Nations will not allow countries to develop space weapons.

Because if aliens don't come, humans will likely aim their superweapons at the earth and at other countries on the earth.

Don't say it's impossible, because according to the history of human war, this is something that will definitely happen.

However, if the aliens really come and cannot guarantee their safety, it will become a very dilemma.

When the Convention on the Contact of Human Civilization and Extraterrestrial Civilization was formulated, it talked about the deployment of weapons in outer space. Because the situation was too complicated, some agreed, some disagree, and some did not know how to agree or disagree.

Time cannot be wasted too much, and there are more treaties to be negotiated, so we first make a decision by voting and discuss it in detail when we have time.

The number of votes turned out to be overwhelmingly "disagree".

It is obvious that if you agree, then the gap between aerospace powers and ordinary countries is not a simple technological gap, but a real civilization gap.

Although the military gap between big and small countries without space weapons is also far different, everyone was on the earth before, but in the future, some countries were on the earth, and some countries were in space. The gap in science and technology, weapons and culture was greater than that between humans and ordinary animals, which is really desperate.

Small countries stubbornly believe that when military equipment and cultural subjects are on the earth, their rights are still guaranteed.

If major powers start to build "space warships" and "space cities", then they will really have no choice.

Tianxia naturally won’t be as blatant as Meriken and directly establishes a space force. It is not a superpower, it is just a small developing country that is recovering.

But those things are not impossible to do, they just need to change the angle.

Although "Aliens" are coming, we still need to do projects that have been finalized before, but we have to change our perspective.

The huge wonder space facility "Sky Space Station" needs to be built, because it is the best transfer station for humans to move to space. Even if it is not built now, it will still be built in the future, not to mention that the mission has been issued to various factories and companies.

Then add something to the Heavenly Court Space Station based on the original basis.

The original Tianting Space Station was a large space station that combines commercial tourism and scientific research. Therefore, in order to strengthen its scientific research functions, electromagnetic catapults and laser arrays were added to it.

Well, it is used for scientific research.

Just like Tianxia’s famous agricultural satellites and farming channels.

As we all know, electromagnetic catapults are used to eject objects and are often related to aerospace. For example, some people want to install electromagnetic catapults on Mount Everest and then directly eject the object into space. They think this is very cost-saving and convenient.

Forget it if you eject a person, it is easy to kill him, but in theory it is still... OK to eject pure goods.

But the ideal is full, but the reality is very skinny.

Not to mention the construction cost of such a huge electromagnetic catapult, it started from the bottom of the Himalayas and continued to the top of Mount Everest. The huge G-force and air friction are enough to drink a pot of goods.

No matter whether you have a small density or a large density, you will become "iron lumps".

But in space, this method is much easier to use.

Already in space, you don’t need to require the initial speed to overcome gravity, and you don’t have to worry about air friction. It is indeed a good way to save fuel and quickly deliver objects.

There are also more people who want to build electromagnetic catapults on the moon, directly along the slope of the crater, and use the characteristics of low gravity and vacuum to launch ore mined from the moon or goods manufactured to the earth through electromagnetic catapults, which is also a time-saving method.

So it is normal to build a few small electromagnetic catapults on the Heavenly Court Space Station for testing.

There is also a laser array, which is also an important testing facility.

Light sailing spacecraft has always been a very popular long-distance spacecraft, especially interstellar long-distance spacecraft. This type of spacecraft does not need to carry a large amount of fuel, but uses huge thin-film lenses to use the radiation pressure of sunlight as the spacecraft's propulsion.

Light shines on the surface of an object and creates pressure. This pressure is very small and is usually difficult for people to measure and detect.

When the sun is strongest at noon and can hit the ground directly, the pressure generated by one square meter of light is less than the weight of an ant.

Such a small force is not enough to push objects to move them, but in space, the effects generated by this force can add up to the "spacecraft" to a very high speed.

But this "accumulative time" is quite long.

Because the sun is so "fraternal" that there is no focus on the illumination from all directions.

If the natural light cannot be achieved, then artificially strengthen it.

Lasers are so fraternal than sunlight. They are more concentrated. The difference between the two is equivalent to breeze and high-speed rail.

The breeze blows all over the world, you can see it anywhere, but it takes a lot of effort to blow a piece of paper.

The high-speed rail can only run on special rails, but if it is criticized, a car can be confronted by you.

Just so happens that the light sailing spacecraft also needs to fly in a certain orbit, so it is perfect to drive it with a laser.

Because there is interference from the atmosphere on the earth, it is most suitable to install laser arrays into space.

Then it is normal to install a few units into the "Tianting Space Station".

Well, in fact, what they are, people who know some techniques should understand, but everything is one name. As long as it is legitimate, there will be less trouble.

If you want to do an experiment, you can also pretend.

Just so happens, even without Tang Chao's assistance, Tianxia's electromagnetic catapult technology and laser emission technology are also among the world's top. With Tang Chao's help, it will be better.

By the way, we also need to install it on the moon, and there are ready-made ideas, namely the lunar crater electromagnetic catapult and the lunar laser array.

Even things built on the moon can be built to become larger. After all, the space station is limited, but the place on the moon can become larger.

The only troubles are the parts transportation and construction aspects.

It would be easy to say if the moon factory was built, but building the moon factory is just as troublesome and extremely time-consuming.

Aliens may come at any time, and "betting on time" is too risky.

Anyway, no matter what, this shows that humans can establish defense lines in space, even if they are weaker, but they can also show an attitude.

The old scientist asked Tang Chao's opinion. After all, the establishment of the space defense line is indispensable for the assistance of the Pilot Company. Both the Heavenly Space Station and the Moon Base have Pilots, and the share is still quite large.

Tang Chaonata had no objection. Anyway, it was all the plans that were finalized before. This time I just added a few small things, but the construction speed may be accelerated because I have to hurry up.

But it doesn’t matter. The company can expand recruitment and adopt new production technology to withstand it.

Time should be fine.

Many professionals have also analyzed that the unknown probe stayed in the orbit of Mars and did not come out, did not move, nor came to Earth. After sending information once, there was no sound. It is very likely that the aliens' technology is not very good.

The reason why we came here is probably like the "Voyager 1" probe launched by humans, it was purely time that we had been so far away.

This unknown probe was captured by the sun's gravity when passing through the solar system. When it passed through the solar system, it did not hit the outer planet, but was still stopped by Mars when it entered the orbit of Mars.

Considering the time factor, the other party's current technology must be more advanced than the detector launch, but it should not be too advanced.

Because if they developed some kind of "super-light speed" flight technology, whether it is space jump or curvature flight technology, the detector flew in this direction. If the goal is clear, then the most advanced spacecraft should arrive first than the detector.

Since the aliens did not come and just the probe arrived, it means that the other party does not have the "super-light speed" mobile technology.

So no matter whether the other party is in the closest trismos galaxy to the earth or other galaxies farther away, after the probe's information is sent back, the other party will send a spaceship over, and it will take at least ten years to go up.

Ten years are very short for the aerospace industry, but it is enough for humans to establish preliminary space defense facilities.

The premise is that humans will not experience major internal conflicts in this short decade, delaying the construction progress.

By the way, the extraterrestrial civilization that launched unknown detectors may regress or even perish.
