Super technology leader

At first, Tang Chao didn't realize it, but later he felt how unwise it was to attend this meeting.

Because of the unknown probe, or directly speaking, the alien probe, the high-level meeting invited experts from various fields and made many assumptions that were as broad as the edge of the universe. The most discussed assumption was how humans should respond after the real aliens arrive.

Or rather, how Tianxia should respond.

The experts divided the hypothesized extraterrestrial civilizations into nine categories: Lawful Good, Neutral Good, Chaotic Good, Lawful Neutral, True Neutral, Chaotic Neutral, Lawful Evil, Neutral Evil, and Chaotic Evil.

Tang Chao was dumbfounded after listening.

Good heavens, are you playing with an alignment chart?

But after thinking about it, it's actually similar, that's the idea.

However, this time they are destined to fight wits with the air, because they have thought of almost all situations, except that the aliens who come may be a bunch of blockheads.

It's just that under normal circumstances, no one would think that aliens are blockheads, and all of them are blockheads.

After all, how could a civilization that has developed to the point of launching a probe into the solar system be dumber than humans in the solar system... right?

Tang Chao can tell everyone the truth: some are.

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

"Xiao Tang, what do you think?"

"Ah, some are."

"Some what?"

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

"I mean the proposal just now, we must be prepared for battle, we can't sit still and wait for death," the old scientist said again.

Tang Chao understood this time, they were indeed talking about defense and counterattack just now.

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

The issue of security must never be handed over to others, nor can expectations be placed on the kindness or evil of others.

Even if human capabilities are limited, they cannot completely open the door and allow aliens to enter and exit at will.

The discussion in the meeting room just now mentioned the matter of deploying weapons in space.

Although the Outer Space Treaty clearly states that it restricts the militarization of space, the Americans have blatantly established a space force, and even want to modify two secondary orbital space shuttles into space fighters, which completely disregards the Outer Space Treaty.

If the Americans can do that, Tianxia can naturally do the same, but before the aliens are confirmed to arrive, the United Nations does not allow countries to develop space weapons.

Because if the aliens don't come, humans are likely to aim those super weapons at the earth, at other countries on earth.

Don't say it's impossible, because according to the history of human warfare, this is absolutely going to happen.

But not developing space weapons, if the aliens really come, it will not guarantee their own safety, which has become a very difficult problem.

The Convention on Contact between Human Civilization and Extraterrestrial Civilization mentioned the situation of deploying weapons in outer space, because the situation was too complicated, there were those who agreed, those who disagreed, and those who didn't know whether to agree or disagree.

Time cannot be wasted too much, there are more treaties to be discussed, so a decision was made first using a voting method, and then discussed in detail when there is time.

The result of the vote was an overwhelming "disagree".

Obviously, if agreed, then the gap between major aerospace countries and general countries would not be a simple technological gap, but a real civilizational gap.

Although the military gap between big countries and small countries without space weapons is also very large, but in the past everyone was on the earth, and in the future some countries will be on the earth, and some countries will be in space. The gap in technology, weapons, and culture is greater than the gap between humans and ordinary animals, which is really desperate.

Small countries stubbornly believe that when military equipment and cultural entities are on the earth, their rights will have some guarantee.

If big countries start building "space battleships" and "space cities", then they really have no way.

Tianxia will naturally not be as blatant as the Americans, directly establishing 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 be changed from another angle.

Don't look at the fact that "aliens" are about to come, but the projects that have been finalized before must still be done, but they also need to be changed from another angle.

The huge spectacle-class space facility "Tianting Space Station" still needs to be built, because it is the best transit station for humans 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 some things to the Tianting Space Station on the original basis.

The original Tianting Space Station was a large space station combining commercial tourism and scientific research, so in order to strengthen its scientific research function, it added electromagnetic catapults and laser arrays.

Well, it's 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 directly eject objects into space. They believe that this is very cost-effective and convenient.

Ejecting people is okay, it's easy to eject them to death, but ejecting pure cargo is theoretically... possible.

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

Not to mention the construction cost of such a huge electromagnetic catapult, starting from the foot of the Himalayas and building all the way to the top of Mount Everest, the huge G-force and air friction are enough for the cargo to drink a pot.

No matter whether your density is small or your density is large, you will all become "iron lumps".

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

Already in space, there is no need to require how fast the initial velocity is in order to overcome gravity, and there is no need to worry about the problem of air friction. It is indeed a good way to save fuel and quickly deliver objects.

Even more people want to build electromagnetic catapults on the moon, directly building along the slope of the crater, using the characteristics of low gravity and vacuum, and launching the ore or manufactured goods mined from the moon to the earth by means of electromagnetic catapult, which is also a time-saving and labor-saving method.

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

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

Light sail spacecraft have always been very popular long-range spacecraft, especially interstellar long-range 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 force.

Light shining on the surface of an object will produce pressure, this pressure is very small, usually people are difficult to measure and difficult to detect.

When the midday sun is strongest and can directly shine on the ground, the pressure generated by light on one square meter is not as large as the weight of an ant.

Such a small force is not enough to push an object to move, but in space, the cumulative effect of this force can make the "spaceship" reach a very high speed.

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

Because the sun is too "loving", shining from all directions, without a focus.

Natural light is not good, then artificially strengthen it.

Laser is different from sunlight, it is more concentrated, the difference between the two to light sail spacecraft is equivalent to a breeze and a high-speed rail.

The breeze blows all over the world, you can see it anywhere, but it is difficult for it to blow a piece of paper.

High-speed rail can only run on special tracks, but if you get hit by it, a car can be pushed into the sky.

Just right, the light sail spacecraft must also fly according to a certain orbit, so it is most suitable to drive it with a laser.

Because there is atmospheric interference on the earth, it is most suitable to install the laser array in space.

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

The latest novel is first published on 69shu.吧!

Cough, in fact, what they are, people who understand some technology should understand, but everything pays attention to a name, as long as it is justified, it will be a lot less trouble.

If you want to do experiments, you can also install them.

Fortunately, even without Tang Chao's assistance, Tianxia's electromagnetic catapult technology and laser emission technology are also world-class. With Tang Chao's help, it will be even better.

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

Even the things built on the moon can be built larger, because the space station has limited space, but the space on the moon is very large.

The only trouble is the transportation and construction of parts.

It will be easier if the lunar factory is built, but building a lunar factory is also very troublesome and extremely time-consuming.

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

Anyway, this shows that humans can establish a defense line in space, even if it is weak, it can also show an attitude.

The old scientist asked Tang Chao for his opinion. After all, the establishment of the space defense line cannot be without the assistance of the Pathfinder Company. The Tianting Space Station and the lunar base both have a share of the Pathfinder, and the share is not small.

Tang Chao naturally has no opinion. Anyway, they are all plans that were finalized before. This time, just add a few small things, but the construction speed may have to be accelerated, because it is necessary to race against time.

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

There should be no problem with time.

And many professionals have also analyzed that the unknown probe stays in Mars orbit and does not come out, does not move, does not come to Earth, and only sends a message once and then there is no sound. It is likely that the aliens' technology is not very good.

The reason why they can come here may be the same as the "Voyager 1" probe launched by humans, purely relying on time to drift so far.

This unknown probe was captured by the sun's gravity when it passed through the solar system, and it did not hit the outer planets when it crossed the solar system, but it was still blocked by Mars when it passed through Mars orbit.

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

Because if they have developed some kind of "superluminal" flight technology, whether it is space jump or warp drive technology, the probe flew in this direction, if the target is clear, then the most advanced spacecraft should arrive before the probe.

Since the aliens have not come, only the probe has arrived, then it shows that the other party does not have "superluminal" movement technology.

Then no matter whether the other party is in the nearest Alpha Centauri star system or other star systems farther away, after the probe's information is sent back, the other party will send a spaceship over, and the time will be at least ten years or more.

Ten years is 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 have major infighting in these short ten years, delaying the construction progress.

By the way, the extraterrestrial civilization that launched the unknown probe may also regress, and even perish is not impossible.

Humans often do great things to die, and there is often a danger of civilization regressing or even perishing. The development of extraterrestrial civilization is certainly not smooth sailing.

The famous "Great Filter Theory" is a concept established for this situation.

Don't say that technologically advanced civilizations will not perish, technologically advanced civilizations perish faster.

People in the Stone Age threw stones when they fought, and if they couldn't beat them, they could run far away and hide.

And humans in the technological age throw nuclear bombs when they fight, and there is no place to run.

More advanced civilizations throw star-destroying weapons, black hole weapons, two-way foil and other things indiscriminately, and there is no slag left to die.

These are all possible situations, but this time humans are destined to fight wits with the air.

I don't know when the four-person team from Canxing will come over, which is a little bit of uncontrollable factor, but no one knows better than him why the unknown probe is "silent".

Because he contacted that probe.

He has been working around the clock during this period. After returning to Tianxia from Sakura Country, he went directly to the Aerospace Bureau conference room, and then went to the United Nations meeting in America. He only went to Canxing on the night in Tianxia, and only stayed for 10 hours.

After the United Nations meeting, he finally had time to return to the company, and then used the highest authority in his studio to send secret information to space.

Werner's communication program directly contacted the probe. He asked the probe to perform a self-check, but the probe couldn't even perform a self-check. Obviously, something went wrong when crossing space.

There was no way, he could only check one by one. After checking, he almost breathed a sigh of relief.

There was indeed a problem with the probe. The control module, energy storage module, propulsion module, communication module, etc. all had varying degrees of damage, so it could not autonomously leave Mars' gravity and could only transmit information through relay equipment.

Moreover, the damage to the control module and energy storage module also prevented it from continuously sending information and needed to accumulate energy, so he intercepted it before the second information was sent. When to send information in the future depends on his order.

He has decided to use this opportunity to let human eyes look more at the stars, so as not to always think about the little broken things on the earth, and stir this and stir that all day long.

After all, the future of mankind is in the universe. As an informed person, letting the "aliens" maintain a threat that is neither too close nor too far away can well guide the progress of human civilization.

The name of the Pathfinder cannot be called for nothing.

The current situation is quite good. All countries are focusing on the stars. Except for those truly foolish individuals who are still being incited to march and demonstrate, wandering the streets all day, everyone else is seriously living their lives and earnestly preparing for the arrival of the new era.

Anyone who isn't calm and doesn't think about the future at a time like this can pretty much predict what their life will be like.

Securing a relatively peaceful environment for the world's development is his responsibility as a leader.
