Chapter 221

In addition to the super stealth performance, the detection ability of the detector also lags behind that of similar equipment on the earth. Among them, in addition to many more advanced optical detectors than the earth, the key is a new way of space detection - gravitational wave detection!

We know that any object with mass can distort space-time. The greater the mass, the more obvious the distortion effect. For example, even light around a black hole can be distorted, and the position shield is a similar principle.

Gravitational wave is a kind of ripple in space-time distortion, which propagates outward from the mass source in the form of wave. This wave transmits energy in the form of gravitational radiation, and the propagation speed is equal to the speed of light. In 1916, Einstein predicted the existence of gravitational wave based on general relativity.

In theory, any object with mass has gravitational waves, and the gravitational wave detection of Gemini civilization is based on such characteristics, so that all spacecraft and celestial bodies have nowhere to hide!

In the universe, short-range detection means such as traditional ground radar are basically useless under huge space distance. Before approaching the effective detection distance, you have long been found by a variety of optical detection equipment including infrared detection! Even the detection range of radar is not as good as the attack range of warships!

Therefore, at present, the detection means of human beings in the universe are mainly optical detectors! Or call it "Guangda"!

However, lidar can be restrained by light stealth technology, but there is almost no way to crack gravitational wave detection.

Needless to say, the position of gravitational wave detection in interstellar war is like radar on earth, which cannot be overemphasized.

However, the drawback is that the gravitational wave detector obtained by Nie Yun is only a small equipment, which is naturally no better than the resolution and performance of the gravitational wave detection radar on the warship.

If you want to get a warship class gravitational wave detection radar, you need Nie Yun to continue to study and improve. Of course... You can also continue to kill strange explosive equipment.

Although the two detectors have different manufacturing processes, the core technology is the same, showing that the technical exchange and integration between the two races of Gemini civilization are still above Nie Yun's imagination.

Even if you can't intermarry, it's at least to the extent of good friends! Nie Yun thought so.

So far, after the two detectors were knocked to the bone and marrow by Nie Yun, the remaining value has been completely drained, and even the body has not been spared. It can be regarded as a worthy death

(detector: "...)

Nie Yun sorted out his harvest a little. From the technology tree of aliens, they are far ahead of the earth in three categories of technology.

That is long-distance navigation technology, quantum technology, graviton technology!

In addition to the galaxy level long-distance navigation technology that can be determined to be owned by the other party, but the specific way cannot be known, quantum computer and quantum communication are both applications of quantum technology.

Position shield, light deflection stealth and gravitational wave detection technology can be classified into the sub science and technology of graviton technology.

It can be seen that the research of Gemini civilization on quantum technology and graviton technology is not overnight, but has formed a complete system!

Regardless of these three types of technologies, there are still a lot of potential to tap. Nie Yun doesn't know how many powerful military technologies he doesn't know about the Gemini civilization, but from the technical level, Nie Yun is undoubtedly at a disadvantage.

In addition, Nie Yun has a huge life gate, which is exposed to the enemy without any disguise!

That's right... That's the earth!

Although the elite of the Freemasons who take the "turtle flow" are selfish, they are not fools. As they consider, the exposed earth is indeed a huge strategic disadvantage that can not be avoided! Always on the verge of destruction.

Although the layout of the two detectors made Nie Yun regain some initiative, this strategic disadvantage will be the fatal weakness of Nie Yun's side as long as the battlefield is still in the solar system.

Nie Yun has simulated the possible war trend of both sides countless times in his mind. However, no matter how to arrange defense, he can't guarantee that the protection of the earth can be foolproof.

It's like the other party has a hostage in his hand. Even if Nie Yun's combat effectiveness is stronger, he can only tie his hands and feet and avoid rats!

However, Zi once said, you can't be too sharp!

In view of the current strategic situation that the enemy is dark and we are clear, and the enemy is strong and we are weak, Nie Yun formulated a very bold plan and gave it a very miraculous name - resurrection from the dead!

……

Thirteen districts of the United States.

The district chief was walking anxiously back and forth, and next to him sat Jay with a dignified face.

In the observation window, a group of scientists kept busy, trying to crack the shield of gravity bomb, and ripples were stirred on the shield from time to time.

And the countdown on the gravity bomb... There are eight hours left.

"Didi!" the mayor's phone rang.

"Hello! How's the situation now?" as soon as the phone was connected, there came some nervous inquiries from the Secretary of defense.

"Eh? Your Excellency, the investigation is over?" the district head was stunned.

"Just over! Damn it, if you let me know who stole my account and invaded the database of the Security Bureau, I * * *" didn't mention the investigation. Fortunately, the mention of the Secretary of defense almost blew up, and a series of blocked words jumped out.

The investigation did not take much time, the Secretary of defense had an alibi, and there were various signs that the Secretary of defense was not suspected of collaborating with the enemy.

The disclosure of confidential documents enough to cause global political unrest can only confirm that the hacker attack was sent from their own internal network, but the investigation has no clue who did it.

Although according to the ghost captain, aliens have invaded the system of zone 13, which seems to be the most suspected, the Secretary of defense thinks it is more likely that the ghost captain is robbing by fire and shouting to catch thieves!

However, under the great threat of gravity bomb, he can only write down this account temporarily. After all, it's almost burning. Who can care about the theft at home!

"Forget it. What about the bomb?"

"Alas! The bomb is still working..." the district chief sighed.

"Where's captain ghost? Aren't they sure?" the Secretary of Defense said anxiously.

"Er... I contacted him several times and suggested that he... Wasn't in the service area..." the head of the district twitched at the corner of his mouth.

Secretary of Defense: "

Not in the service area?! what the fuck! How can you lose contact at the critical moment? Is there any sense of responsibility?!

After hanging up the communication, the Secretary of defense recalled the ghost captain's dog head mask face, and the more he thought about it, the more he felt that it was unreliable!

Eggs can't be put in one basket!

Gritting his teeth, he dialed a phone, "Hello! This is the Secretary of defense. Inform all senior officials to hold an emergency meeting at the highest level immediately!"

Soon after, in a secret conference room, there was a scream and noise, followed by a miscellaneous quarrel

As Nie Yun imagined, as death approached... Panic inevitably... Began to spread
