At first, he didn't feel it, but later Tang Chao felt that it was an unwise choice for him to participate in this meeting.

Because of the unknown probe, or directly about the alien probe, the high-level meeting invited experts from various fields and made many assumptions that were wide to the edge of the universe, and the most common assumption was how human beings should deal with it when the real aliens came.

In other words, how should Tianxia deal with it.

Experts divide hypothetical extraterrestrial civilizations into nine categories, namely Orderly Good, Neutral Good, Chaotic Good, Orderly Neutral, Complete Neutral, Chaotic Neutral, Orderly Evil, Neutral Evil, and Chaotic Evil.

Tang Chao looked stunned after hearing this.

Good guy, are you playing the camp nine-square grid on hold?

But if you think about it, it's actually pretty much the same, that's what it means.

But this time they were destined to fight the air, because they had thought of almost all the situations, but they didn't expect that the aliens who came might be a group of iron Hanhan.

It's just that under normal circumstances, no one would think that the aliens are Tie Hanhan, or the kind of Tie Hanhan who is all the members.

After all, the civilization that can develop to the level of launching probes into the solar system cannot be more stupid than the humans in the solar system...... Right?

Tang Chao can tell everyone the truth: Yes.

Of course, there is still a difference between stupidity and criticism.

"Don Jr., what do you think?"

"Ah, yes."

"What's there?"

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

"I mean, we have to be ready to fight, we can't sit idly by." The old scientist said it again.

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

Tianxia is very familiar with this matter, and it has been doing this since the founding of the country.

The issue of security must not be left in the hands of others, nor can expectations be placed on the good and evil of others.

Even if human beings are limited, they can't completely leave the door open for aliens to enter and exit.

That's all we talked about in the conference room just now, about the placement of weapons in space.

Although the "Outer Space Treaty" clearly states that the militarization of space is restricted, the United States has already brazenly established a space force, and even wants to convert two types of space shuttles into orbit into space fighters, which is no longer taken seriously by the "Outer Space Treaty" at all.

Merriken can do that, and Tianxia can naturally do that, but until the arrival of aliens is confirmed, the United Nations will not allow countries to develop space weapons.

Because if the aliens don't come, humanity is likely to aim those superweapons at the Earth, at other countries on the Earth.

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

However, without the development of space weapons, if aliens really come and cannot guarantee their own safety, this will become a very dilemma.

When the Convention on Contacts between Human Civilization and Extraterrestrial Civilization was formulated, it talked about the deployment of weapons in outer space, because the situation is too complicated, and there are those who agree, those who disagree, and those who do not know how to agree or disagree.

There is not much time to waste, there are more treaties to negotiate, so a decision was made by voting first, and then we will discuss it in detail when we have time.

The result was an overwhelming "disagree" vote.

Obviously, if it is agreed, then the gap between the space powers and ordinary countries is not a simple scientific and technological gap, but a real civilization gap.

Although there is a big gap between large and small countries that do not have space weapons, the gap between everyone on the earth in the past and some countries on the earth and some countries in space is greater than the gap between humans and ordinary animals.

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

If the major powers start to build "space battleships" and "space cities", then they really can't do anything.

Tianxia will naturally not be as blatant as Merrican to directly establish a space force, it is not a superpower, it is just a small developing country that is recovering.

But it's not that those things can't be done, they just need to be looked at from a different angle.

Don't look at the "aliens" are coming, but the projects that have been finalized before should still be done, but they also have to change their perspectives.

The huge spectacle space facility "Heavenly Court Space Station" still needs to be built, because it is the best transit station for human beings to go to space, even if it is not built now, it will be built in the future, not to mention that the tasks have been issued to various factories and companies.

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

The original Tianting space station was a large-scale space station that combined commercial tourism and scientific research, so in order to strengthen its scientific research function, an electromagnetic catapult and laser array were added to it.

Well, it's for scientific research.

Just like Tianxia's famous agricultural satellite and farming channel.

As we all know, electromagnetic catapults are used to catapult objects, and are often related to aerospace, for example, some people want to install electromagnetic catapults on Mount Everest, and then directly catapult objects into space, they think that this is very cost-effective and convenient.

Even if you eject people, it is easy to bounce to death, but ejecting pure cargo is still theoretically ...... OK.

It's just that the ideal is very plump, but the reality is very skinny.

Not to mention the construction cost of such a huge electromagnetic catapult, it was built from the bottom of the Himalayas to the summit of Mount Everest, and the huge G-force and air friction alone are enough for the goods to drink a pot.

It doesn't matter if you are small or dense, you will become an "iron lump".

But in space, it's much easier.

If you are already in space, you don't need to ask for muzzle velocity to overcome gravity, and you don't have to worry about air friction, which is indeed a good way to save fuel and quickly deliver objects.

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

Therefore, it is normal to build a few small electromagnetic catapults on the Heavenly Court space station for testing.

There are also laser arrays, which are also an important test facility.

Lightsail spaceships have always been very popular long-distance spacecraft, especially interstellar spaceships, which do not carry a lot of fuel, but use huge film lenses to use the radiation pressure of sunlight as the propulsion of the spacecraft.

Light on the surface of an object creates a pressure that is so small that it is usually difficult to measure and imperceptible.

When the midday sun is at its strongest and hits the ground, the pressure generated by one square meter of glazing is less than the weight of an ant.

This small force is not enough to propel an object into motion, but in space, the effects of this force can add up to a very high speed for the "spaceship".

It's just that this "cumulative time" is quite long.

Because the sun is too "fraternity", the radiation in all directions does not have a focus.

Natural light does not work, then artificially strengthen it.

The laser is different from the sunlight, it is more concentrated, and the difference between the two is equivalent to the breeze and the high-speed rail.

The breeze blows all over the world, and 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 you are struck by it, a car can scare you to the sky.

It just so happens that the light-sail spacecraft also has to fly according to a certain orbit, so it is perfectly suitable to drive it with a laser.

Because there is atmospheric interference on Earth, it is most appropriate to install laser arrays in space.

Then installing a few units on the "Heavenly Court Space Station" is also a normal operation.

Ahem, in fact, what they are, people who know some technologies should understand, but everything pays attention to a name, as long as the name is right, it will be a lot less trouble.

If you want to do experiments, you can pretend to do that.

It just so happens that even without Tang Chao's assistance, Tianxia's electromagnetic ejection technology and laser emission technology are also the top in the world, and with Tang Chao's help, it will be even better.

By the way, the moon also needs to be installed, and there are just ready-made ideas, that is, the electromagnetic catapult of the lunar crater and the lunar laser array.

Even things built on the moon can be made bigger, after all, the space station has a limited space, but the place on the moon can be bigger.

The only trouble is the parts shipping and construction aspects.

It's easy to say if you wait for the moon factory to be built, but building a moon factory is just as cumbersome and time-consuming.

Aliens could come at any time, and "gambling on time" is too risky.

Anyway, it shows that humans can build a line of defense in space, even if it is weaker, but it can also show an attitude.

The old scientist asked Tang Chao's opinion, after all, the establishment of the space defense line is indispensable to the assistance of the Navigator Company, and the Heavenly Court Space Station and the Moon Base both have the share of the Navigator, and there are quite a few shares.

Tang Chao naturally has no opinion, anyway, it is all a plan that has been finalized before, this time it is just a few small things, but the construction speed may be accelerated, because it is in a hurry.

But it doesn't matter, the company can expand and recruit workers, and it can also adopt new production technologies to withstand it.

The timing should be fine.

And many professionals have also analyzed that the unknown probe stayed in the orbit of Mars and did not come out, nor did it move its nest, nor did it come to Earth, and it only sent a message once and then there was no sound, and it is likely that the technology of aliens is not very good.

The reason why I was able to come here may be the same as the "Voyager 1" probe launched by humans, it is purely because of time that it has traveled so far.

The unidentified probe was captured by the sun's gravity as it passed through the solar system, and it didn't hit the outer planets when it passed through the solar system, but it was stopped by Mars when it entered the orbit of Mars.

Considering the time factor, the other party's current technology is definitely more advanced than the era when the probe was launched, but it should not be too advanced.

Because if they develop some kind of "faster-than-light" flight technology, whether it is space jumping or curvature flight technology, and the probe flies in this direction, if the goal is clear, then the most advanced spacecraft should arrive before the probe.

Since the aliens did not come, but the probe arrived, it means that the other party does not have "faster-than-light" mobile technology.

So no matter whether the other party is in the trimaran galaxy closest to the earth or other galaxies that are farther away, after the information of the probe is sent back, the other party will send a spacecraft over, and the time will be at least ten years up.

Ten years is a short time for the aerospace industry, but it is enough for mankind to build a preliminary space defense facility.

The premise is that there will be no major infighting in this short decade, delaying the construction progress.

By the way, it is not impossible for the extraterrestrial civilization that launched an unknown probe to regress, or even perish.

On the human side, there are often great deaths, and there is often the danger of civilization regressing or even extinction, and the development of extraterrestrial civilizations is certainly not smooth sailing.

The well-known "Great Filter Theory" is a concept set up for this situation.

Not to mention that advanced science and technology will not perish, and advanced civilizations will die faster.

Stone Age people fought by throwing stones, and if they couldn't hit it, they could run away and hide.

In the age of science and technology, human beings have thrown nuclear bombs when they fight, and there is nowhere to run if they want to.

In a more advanced civilization, what kind of star-destroying weapons, black hole weapons, two-way foil and the like are thrown around, and the dead scum is gone.

These are all possible scenarios, but this time humanity is destined to battle the air.

Kanxing's four-person team didn't know when it would come, which was a little uncontrollable, but it was unknown why the probe was "silent", and no one knew better than him.

Because he got in touch with the detector.

He has been rotating continuously during this time, and when he returned to Tianxia from the cherry blossom country, he directly entered the conference room of the space agency, and then went to Merrican to attend the United Nations meeting, and he went to Kanxing on the night of Tianxia, and only stayed for 10 hours.

After the UN meeting, he finally had time to return to the company, and then used his studio to launch secret messages into space with supreme authority.

The communication program given by Werner directly contacted the probe, and he asked the probe to perform a self-test, but the probe could not even do the self-test, apparently something went wrong while traveling through space.

There was no way, he could only check them one by one, and he was almost relieved when he was done.

The probe did have problems, and the control module, energy storage module, propulsion module, communication module, etc., were damaged to varying degrees, so it could not get out of the gravitational pull of Mars on its own, and could only transmit information through relay equipment.

Moreover, the damage to the control module and the energy storage module also made it unable to continuously send messages, and needed to accumulate energy, so he intercepted it before the second message was sent, and when to send the message in the future, wait for his command.

He has decided to take advantage of this opportunity to let human eyes look at the starry sky more, and save always thinking about the little on the earth, mixing this and that all day long.

After all, the future of mankind is in the universe, and he, as an insider, can keep the "aliens" in the near and distant deterrence, which can well guide human civilization forward.

The name of the Navigator cannot be called in vain.

The current situation is very good, the eyes of all countries are looking at the starry sky, except for those who are really innocent and still being encouraged to march and demonstrate, wandering the streets all day long, everyone is seriously living their lives and seriously preparing for the arrival of a new era.

If you don't calm down and don't think about the future at this time, you can basically predict what your life will be like in the future.

It is his responsibility as a leader to strive for a relatively peaceful environment for the development of the world.
