Guide to Galactic Dominance

Checking the data in his hand, Ye Qing, a dark-skinned but very handsome young Chinese physicist, couldn't help but sigh. He put down the detection data in his hand and said, "As expected, it really can't be detected."

His mentor, Academician Ding, who leads many large-scale aerospace projects and secret defense projects in the country, is not as downcast as he is. Instead, he has a calm attitude. Academician Ding said: "This is also natural. The other party's technical level is different from ours." Too many, and measuring them against what we understand might be like measuring modern nuclear reactors against a group of Neanderthals using their skills in drilling wood to make fire."

Ye Qing thought for a while and said: "Our intelligence personnel received information from the United States that the US military did not obtain any electromagnetic signals from alien fighters during the San Francisco incident. In this way, those warships in Earth orbit also It should be the same technology used.”

Academician Ding said: "This is not surprising. If we can detect it using multiple methods, then it is something worthy of doubt."

China has just built the world's largest single-aperture radio telescope FAST this year, and it is also one of the most powerful astronomical detection tools in the world. It can not only detect pulsars and other celestial objects thousands of light-years away, but also can be used as a super-large passive strategic radar due to its high sensitivity. But even with such a powerful astronomical detection tool, it still hasn't detected any information about the mysterious alien fleet. This makes people feel very powerless.

There is a difference of forty years between the two, but they are both the top geniuses in this country. In order to deal with this unprecedented crisis of contact with extraterrestrial civilizations, China established the "Extraterrestrial Contact Countermeasures Office", which convened elites from various fields and was directly responsible to the National Security Council to analyze and explain various types of intelligence it had obtained, and at the same time conduct research. means of defending the country and its people in crises. Both Ye Qing and Academician Ding were elected to this countermeasures office.

Liu Tong, an official of the State Council who parachuted into the office to serve, hurriedly walked in from the outside and said to the two of them: "At this time, the Americans are still ostracizing us and refusing to reach any negotiation and cooperation mechanism with us. They are determined to Solve the problem yourself.”

After hearing Liu Tong's words, Ye Qing sneered and said, "Solve it yourself? They haven't even cleaned up the mess in San Francisco. Our country is generally stable, and production and life have not been disturbed too much. I heard that the United States has already There have been riots of varying sizes in more than 20 cities, and the National Guard has been dispatched. I can't handle it myself, and I want to deal with aliens. It's just a fantasy."

Academician Ding frowned and said: "Americans are used to acting arbitrarily, but at this juncture, they can't help themselves. The Americans refuse to cooperate with us. I'm afraid they already have their own plans, and This would definitely be a bad idea."

Facts have proved that Academician Ding’s speculation is extremely correct.

More than four hours later, China's missile defense system detected a large-scale missile target in the United States, which was launched almost at the same time.

Ye Qing couldn't help but feel his scalp tingling when he looked at the drawing image on the screen in the office, and said loudly: "The Americans are crazy!"

Liu Tong was also horrified by the actions of the Americans. He checked the information he had obtained and said: "The 90th, 91st and 341st strategic missile wings of the United States, which maintain a high degree of combat readiness, have deployed a total of more than 70 strategic ballistic missiles. , they have no reason to fight a nuclear war at this time, that is, they will use nuclear weapons to bomb the alien fleet! Dr. Ye, do you think the Americans can succeed?"

Ye Qing shook his head repeatedly: "The destructive effect of nuclear weapons in outer space is far less than that on the ground. Without air, the shock wave in nuclear weapons that can cause the greatest damage no longer exists. The greatest damage caused by nuclear explosions in space comes from various sources. Radiation, high heat and neutron jets, etc., the damage range will also be smaller than that of nuclear explosions in the atmosphere.

But this is not the biggest problem in this attack. The missile used by the Americans should be Minuteman III, and the alien fleet is in orbit 200,000 kilometers above the surface. Ordinary ballistic missiles cannot reach this altitude. of. Since the Americans are rushing to attack the missiles, it means that these weapons have been urgently improved and are even secret weapons that the United States has concealed. It is not enough to be able to fight this far. This is the first time that humans have purposefully carried out actual combat against space targets. There is a huge disconnect between tactics and reality. We are not sure whether the United States has done relevant pre-research and deductions.

The most important issue I can think of is the probability cloud theory of space warfare. This is a very central part of people's speculation about space warfare. The speed of light in a vacuum is constant, and one party's observation of a long-distance enemy's autonomously maneuverable aerospace weapons will be affected by the delay effect. The distance of one light second is about 300,000 kilometers. The alien fleet is now about two-thirds of a light second away from the earth. So even if we conduct real-time optical observations, we will only see the image of the other party two-thirds of a second ago. If the opponent continues to maneuver, it is absolutely impossible for the weapon aimed at the opponent's target to hit the target. Even with directed energy weapons. Therefore, in a space battle, one can only make a rough calculation of the probability cloud space based on the relative position of the opponent and its movement performance. This is a question of quantum mechanics. The target position of our attack may be any three-dimensional coordinate point within the probability cloud. The better the opponent's mobility, the greater the initial velocity and acceleration, and the more flexible the steering, the larger the probability cloud will be. , the lower our probability of hitting.

However, the biggest problem for the Americans now is that their weapons are not directed energy weapons and cannot reach the speed of light. Judging from the missiles they launched, it was actually a modified version of a large rocket, exceeding the first cosmic speed and less than the second cosmic speed, that is, above Mach 23 and below Mach 33. And this speed can only reach the level of five or six digits after the decimal point of the speed of light. Because the Americans do not have the technology to guide the radar of the alien fleet, it is basically only possible to use inertial guidance. Without discussing the deviation of the inertial navigation, it is just a slight displacement when the other party discovers that the Americans are launching missiles. The Americans The nuclear bomb cannot hit. Nuclear explosions have a weak killing range in space. Even if the Americans use fixed depth detonation and multiple killing surface effects to form a killing range area, I don’t think this killing range area can completely cover the space battle probability cloud of the alien fleet. . "

Liu Tong didn't quite understand what Ye Qing was talking about, so he naturally didn't understand it. From his understanding, although he didn't know what this probability cloud was, he thought simply that the aliens' technology was so powerful, and the vacuum-weakened version Even if a nuclear explosion hits the alien fleet, it may not cause any real harm.

Liu Tong asked curiously: "Don't Americans understand what Dr. Ye said?"

Academician Ding answered this question for Ye Qing, "It is impossible for them not to understand that the United States' achievements in space warfare, basic physics, game theory, etc. cannot be matched by our country's decades of catching up. They have no idea. Having a deep reserve is still our teacher. However, the person who makes the decision is not a physicist, and in such a situation, people always have some luck. They will think, what if they hit it? ?”

Liu Tong was shocked: "Are you just pinning your chances on such an unreliable gamble?"

Academician Ding said: "There is nothing we can do about it. The emergence of aliens has completely broken the balance of power on our planet and has also seriously threatened the existence and international status of the United States. Although this matter is ultimately a common problem shared by 7.5 billion people around the world. They have to face it, but Americans have such a strong savior complex that they cannot escape from this trap. Aliens do not communicate with the earth, and they look like a menacing military invasion. It is impossible for Americans not to make some reactions. , even if it has no effect.”

Liu Tong's voice was a little off-key, and he said in disbelief: "The Americans are so irresponsible! If aliens are really angry at the earth, then people all over the world will suffer!"

Academician Ding was not surprised by this, and just said calmly: "Yes, it is the same as the nuclear bundling back then. Even if the United States is going to be finished, then the whole world will be finished with it."

Ye Qing snorted and said, "To put it in current terms, all of us in the world are 'represented' by the United States."
