The reason why a black hole is called a black hole is that it can devour light and let it go where it is, even if it reaches the final stop, there is no need to go anywhere else. {We don't write novels, we're just online text porters-casual-dream-fiction wwwlā.}

But in fact, even black holes have radiation, which is what we usually call Hawking radiation. Black holes can only 'survive' in the universe if they reach a certain mass, and if they are too small, they will slowly evaporate their 'Hawking radiation', and there will be no zài.

For a black hole to exist, there must be light for it to swallow, and if there is no light, the black hole will not always exist.

Black holes are an extreme astrophysical phenomenon, and with the current technology of human beings, it is difficult to create such extreme objects.

Therefore, if human beings want to make any invisible objects such as invisibility cloaks, they should not think about making it into something with a huge gravitational force, but only think about making it into an object that can bend light. And how to do this, people have not yet reached such a level of technology. I don't know how to make it truly invisible and manufactured.

Let's go back to stealth missiles. It's not like a black hole that swallows up light. At most, it can change the direction of reflection of the radio signal, so that the radar cannot receive the transmitted signal.

But in fact, even if this is the case, it is impossible for the stealth missile to really reflect all the radio signals to other places, and there must be some radio signals that still return to the radar receiver.

The key is that these reflected signals are too weak, so the radar can't distinguish them, so that the stealth missile can achieve the purpose of stealth.

After some thought, Zhao Zhongyao had found out what the stealth principle of the stealth missile developed by Jonnis and Wesley was.

"Zhongyao, then you say, how are we going to deal with the enemy's stealth missiles!" Yan Mingcheng listened to Zhao Zhongyao's words, looked at him with some concern and said.

"We only have to develop one more advanced air defense radar. As long as the power of the radar increases, the radio signal emitted is very strong, so that the stealth missile can block some signals. There will still be a lot of signal reflected back to the radar's receiver. Zhao Zhongyao once again re-examined, if he wants to deal with the enemy's stealth missile, he can only develop another radar facility.

"Medium Reach, that enemy stealth missile above. What kind of anti-jamming equipment is installed, how can it be so powerful!" Yan Mingcheng still didn't understand this question.

"I think it's quite possible that it's a powerful electromagnet. This electromagnet can generate a powerful electric field, which can surround stealth missiles. Such. The radar waves emitted by our radar, when they reach the enemy's stealth missiles, will weaken these electric fields, or they can be said to be shielded by the electric fields. ”

Although Zhao Zhongyao did not see what the stealth missile developed by the enemy looked like, he still started from the knowledge of radio and speculated what the anti-jamming equipment used by the enemy would be!

"Oh, is it just an electromagnet!" Yan Mingcheng was a little surprised when he heard what Zhao Zhongyao said, and felt that the electromagnet was just an ordinary thing. How can it be so useful!

However, we haven't seen any stealth missiles, and I don't know how they did it, and I'm just speculating about it now. ”

Zhao Zhongyao didn't dare to conclude how the enemy's stealth missiles were made, he just speculated with the knowledge he knew.

"Zhongyao, then what are you waiting for, let's hurry up and develop a new type of radar!" Yan Mingcheng heard Zhao Zhongyao say this, he just wanted to develop a new type of radar as soon as possible!

"Yes! I'm going to hurry up and develop a new radar now. Otherwise, if the enemy fires another missile at Mushroom Island, it will be over, and the two of us will wait for the criticism of the leader!"

Zhao Zhongyao also knew. If the enemy succeeds in launching missiles this time, they will certainly develop some more such stealth missiles, and if they do not quickly find a way to deal with them, they will be caught off guard if they wait for many missiles to be launched at once.

"Okay, Haruka. You design a new radar first! I'm going to find some raw materials. Yan Mingcheng knew that if he wanted to develop a new type of radar, he would have to find some raw materials again. I'm afraid it won't work just with the original materials!

"Okay, then go your separate ways. ”

Zhao Zhongyao said as he took out some design drawings, sharpened a pencil, and then began to design a new radar.

In fact, this new radar is not much different from the original radar, that is, the transmitter used to emit radio waves is twice as powerful as the previous one. Everything else is pretty much the same, and there's not much difference in appearance.

In this way, Zhao Zhongyao only took two days to design the drawings of this new radar.

After the design was completed, he found Yan Mingcheng and asked him to quickly regenerate an air defense radar according to the drawings. In this way, it is good that when the enemy attacks again, the enemy's stealth missiles can be detected.

Yan Mingcheng hurriedly led some workers to produce a new type of air defense radar. Since this new air defense radar is not much different from the original, but the power is a little larger, it has not encountered any problems in production.

Thanks to everyone's efforts, it only took one week to develop this new type of air defense radar.

After the development was made, Zhao Zhongyao and Yan Mingcheng hurried to the radar monitoring room, removed the original air defense radar, and put this new air defense radar on it.

After putting it away, it was quickly debugged again, and then this new air defense radar began to work.

Besides, Jonnis and Wesley are happy now.

You must know that this is the first time that they have successfully launched missiles into the territory of China! Previously, country F had purchased 36 of their missiles. Country F used these 30 missiles to compete with China's cruise missiles.

But the result was that all 10 of China's 10 cruise missiles were destroyed by their 36 missiles. Thirty-six missiles, not a single one lagged behind the territory of China.

This incident not only made country F very angry, but also made Joannis very faceless. After all, the missiles purchased by country F from country M were all developed by Joannis at the head of him! But the result was that none of these missiles hit the territory of China, and this did not make Joannis very embarrassed.

This time, in the military competition with Huaguo, the ballistic missile he developed before failed again. After a long time, he had to give up the original research plan. We had to produce Wesley's stealth missiles!

But no matter what. The stealth missile developed by Jonnis and Wesley really saved some face for Jonis. Finally hit the territory of Huaguo. Although this stealth missile only hit the mushroom island where there were no people and no buildings on it. It did not cause any loss of personnel or property to Huaguo. But after all, it hit the territory of Huaguo. For Jonis, this is already a huge step forward and he is already feeling proud.

Now Jonnis looked at Wesley and smiled, "Wesley, you're amazing! It seems that it's time for my old military engineer to retire." You're up to my part!"

Wesley, of course, couldn't brag in front of the teacher, he glanced at the teacher, and then said modestly: "Teacher, what are you talking about? I'm still far from you! In the future, I want the teacher to help me more and let me learn some knowledge about engines! Although I know a little about radio, I am far inferior to you in terms of engines!"

Wesley was telling the truth, he was good at radio. In other respects, he is not very good, especially in terms of engines, he can be said to be far inferior to Jonis!

"Haha, of course, you can follow me in the future, and I will tell you all the most advanced knowledge of engines that I know. I want to train you to be the most famous military expert in our country M. ”

Jonnis already values Wesley very much now, and feels that this kid will be able to surpass him Joannis in the future. Become the most famous military industry expert in country M.

"Teacher, don't talk about this, are we going to develop a few more stealth missiles! Last time, although it was launched on Mushroom Island. But it didn't work, and there were no people on Mushroom Island. There are no military facilities!"

Wesley thought that the last time the missile he developed hit the mushroom island in Huaguo, it was on that island. Now there is no permanent population, so to speak, a desert island! There are some troops on it, guarding the uranium mine site above Mushroom Island.

This time, although the missiles launched by Joannis and their missiles were successfully launched to Mushroom Island, they did not cause any loss of life or property.

This is a good thing for Huaguo, but not for Jonnis and Wesley.

Any weapon is used to destroy an opponent and destroy an opponent's buildings or military installations. If a missile is launched and no military facilities are blown up, then there is no point in launching this missile!

"But, where do you want to hit the stealth missile? Do you want to hit Jianghai City in Huaguo? I'm afraid that the range of your missile is not that far, and if you want to hit Jianghai City, I'm afraid that it will be beyond the reach of some whips!"

Jonnis knew exactly how far Wesley's missile could hit, and he also knew how far their small island was from Jianghai City in eastern China. It's almost 3,000 kilometers! It is impossible for an ordinary missile to hit such a long distance.

Their stealth missiles can hit Mushroom Island to the limit, and it is basically impossible to hit Jianghai City in Huaguo.

"Teacher, what you're saying is that our stealth missiles can't hit Jianghai City in eastern China at all, but we can hit another small island not far from Mushroom Island. ”

Wesley seemed to have an idea of his own.

"What, hit the island near Mushroom Island. Isn't it just a shark island? As far as I know, there are no people on that shark island! It's just an uninhabited desert island!"

Jonnis listened to Wesley, and he objected again. Because Joannis thinks he knows China very well, including some small islands in the East China Sea, he also knows it very well.

"Teacher, but I recently got some information that there are people on that shark island in the East China Sea now!"

Wesley was an extremely intelligent man. Not only can he develop military weapons, but he also has a hand in the military!

Last time, the stealth missile they launched, although it hit Mushroom Island, it had no effect, and there was no one on Mushroom Island. Although there were some defenders, they were few in number. Besides, Joannis and the others don't know that there are some garrisons of China on Mushroom Island, guarding the uranium mining area!

Now for Jonnis and Wesley, it feels like there is no point in firing missiles at Mushroom Island again, and they want to change the target!

And Jonnis didn't know where to shoot yet! He even said that he was going to launch missiles at Shark Island, near Mushroom Island in the East China Sea!

The reason why Wesley said this was because the last time he knew that the stealth missile they launched was on Mushroom Island and didn't hit any buildings or people, he wanted to change the target!

So he secretly sent some people to some small islands near Mushroom Island to see if there were any Chinese personnel operating on them.

On this small island where they developed weapons, there were also some soldiers of country M, who were protecting Jonnis and Wesley, after all, this was a military research base, and it was also necessary for the army to protect it.

Wesley had some of the warriors disguise themselves as ordinary fishermen and take a large fishing boat to the vicinity of Mushroom Island. First, he came to see if the buildings on Mushroom Island had been destroyed after the last missile attack on Mushroom Island, and whether there were casualties among the Chinese people on Mushroom Island.

Second, he just wants to let these fake fishermen see if there are any personnel activities on the nearby islands, and if there are any, they can attack other islands next time.

After some reconnaissance, these fake fishermen really found that there seemed to be people on a small island called Shark Island near Mushroom Island, and they were far away, of course, they couldn't see the specific situation on the island.

Just looking through the binoculars, there seem to be some improvised structures on this small island, as well as some fishing nets. So they concluded that there were Chinese people on this small island. Probably some fishermen who fished. (To be continued.) )
