Qinglan Consulting, project code name c, fourth meeting.

When the meeting started, Rao Xin looked around. Unlike the last time there were more than a dozen people, there were very few people attending the meeting this time. He himself, Professor Shen from Qinglan Consulting, an engineer who is said to be from the United States, There is also a nuclear physics expert who was in the same discussion group last time. The expert's surname is Tian. Rao Xin only heard Professor Shen call him Lao Tian-they should know each other.

In front of these bigwigs, a video is being played three times on No.30.

Professor Shen and Professor Tian were talking to each other in a low voice. The American stared and shook his head while counting things on the paper.

It can be seen that they have seen a lot of things in the previous 32 times, and they are still learning more.

Especially the American, when he played it for the first few times, he wanted to search for information frame by frame, and find out any questionable points to question Shen Changwen.

Only Rao Xin himself, from the first time to the present, he hardly felt any difference in what he saw, nor did he think of more things because of it. In his opinion, the content in this short ten-second video , is very simple, so simple that all the information can be summarized in one sentence.

In a zero-gravity environment, a person used a laser to cut 240 swords and kill 240 people in two seconds.

Information is simple, not simple, and it is a specific elaboration of these information.

Although the entire video is short, it contains a lot of information. The angle of view is rotated and zoomed in, and the definition of each shot is extremely high. There are several gigagrams in the converted data in just a dozen seconds, and each of them Each picture can withstand dozens of times of magnification to ensure that the details are still clear-this alone is far beyond the needs of ordinary movie pictures, and also beyond the conceptual scope of conventional special effects production-it does not look like an ordinary big picture. make.

The frame frequency of the video itself is also far higher than the shooting needs of ordinary movies, reaching more than 300 frames per second, which is five times that of ordinary movies.Of course, this is nothing compared to the content of the screen itself.

The work they have to do has nothing to do with how these pictures are realized. They need to analyze, assuming that the content in the pictures is true, how to evaluate the power of the weapons and possible means of confrontation.

First of all, the most important detail, which the American has emphasized many times, is the energy level assessment of this laser—this is what they mainly analyzed in this meeting.Calculated from the time on the screen, the laser lasted a total of 480 seconds from its appearance to its end. During this period, the laser always maintained such an obvious operation process: lock the target, move and track, destroy Target, lock on to the next target...the number of all targets is 5, that is to say, the average time to lock and destroy a target is only 5 milliseconds—for example, the speed at which a bee flaps its wings is [-] milliseconds Once, that is to say, within the time that the bee flapped its wings once, the laser beam successfully destroyed the target.

And the recording frequency of this video is [-] frames, that is, an average of [-] milliseconds per frame-in the time of two frames, the laser just completed the task of locking and destroying.Zooming in on the video, it can be clearly seen that those destroyed flying swords and human bodies have obvious physical processes of being vaporized by high temperature. The other three people have simply calculated on paper that to achieve this effect, at least Energy level - the conclusion is obvious, the temperature of the laser itself is at least on the level of hundreds of thousands of degrees, or even millions of degrees - this even exceeds the temperature inside many stars.

This alone shows that if civilizations possessing this weapon really exist, then their technology is far beyond the earth... I don't know how many levels.

On earth, there is only one place where people can create such a high-temperature environment through equipment, and that is the inertial confinement nuclear fusion device that is still in the experimental stage.Similar to the domestic Shenguang Project and the US National Ignition Device, such lasers are focused together by hundreds of laser generators, and can only be maintained for a short time after the nuclear fusion is finally activated. However, in the picture, it is completely outdoor In a natural environment, the generating device is just a stick, and the duration from generation to contact is very short, just like switching a flashlight once-this is enough to show that the reliability of this device itself is very strong.

"And the controls, which are more incredible than the power levels."

"Have you noticed the movement of the device's own angle - pay attention to the hand muscles of the operator in the video..."

"You can try holding an object in your hand. When you are about to adjust the angle of the object in your hand, there will definitely be a slight muscle twitch, but there is no such movement in the picture, but the angle of the control device itself is slightly moving. Variety."

"That is to say, from locking to destroying, the whole process is fully automatic - I don't believe that the human reaction speed can reach the millisecond level, so many operations can be completed in a short period of time - this is completely beyond the transmission of nerves Speed." This sentence is what Professor Shen is saying. Compared with the previous speech, he first said it to Professor Tian and Rao Xin in Mandarin, and then said it to the American in English.

The American was lost in thought and began to calculate on paper again. After a while, he stopped and nodded to Shen Changwen.

Professor Tian added a point of view: "It can be seen from the picture that the angles of the entire fine-tuning are very different. When we look at the first destruction, the 220 swords are almost distributed in all angles of the entire field of view, which is very uniform. There are one coordinate point distributed over a square kilometer, and the average angle between every two coordinate points is about 20 degrees, pay attention to its moving trajectory, I used tracking software to automatically draw a trajectory map, take a look."

Professor Tian opened the video again from the computer, switched to the clip he mentioned, and then Rao Xin was surprised to see that all the trajectories scanned by the red laser were recorded—during the high-speed flight of those flying swords, the red The laser is like threading a needle, from the first target, to the second, to the third...

The whole process perfectly followed the scanning method of the stereographic projection——the trajectory of the laser is a very beautiful spiral curve. It starts to move from the place where it just started, and gradually expands the radius of travel in the order from near to far. Like an invisible hand, it delicately controls the light to stir in the space.This process does not move at a uniform speed, but is accompanied by the process of acceleration, stop, re-acceleration, and then stop-every short moment of stop is the process of laser focusing on the target and releasing energy.

Rao Xin also discovered a noteworthy detail during this process - when the laser leaves a target, it is impossible to distinguish whether the target has been destroyed or not from the screen alone, and those swords even maintain their overall shape. The shape and stable flight status continued to fly, but the laser just left by itself.

It wasn't until the entire destruction process was nearing the end that the first destroyed target sword body began to break and separate.

"This means that the laser has very mature parameters for destroying these targets, and at the same time, the energy is saturated and overloaded-so that the destruction can be ensured. If it leaves without destroying, it is extremely wasteful in terms of efficiency."

In layman's terms, comparing a laser to destroying a flying sword is like knocking down a person with a punch, it sounds easy to do, but to knock down 240 people in a row in a very short period of time means that the boxer It is necessary to have a very accurate estimate of the strength of one's own shot and the opponent's ability to resist blows, in order to ensure that each blow does not waste too much effort, and to ensure that each punch can be truly knocked down.

"In terms of weapon design, we usually have to leave a margin of 25%, or even more than [-]%, in terms of lethality. In specific combat behaviors, it is necessary to project hundreds or thousands of times the necessary firepower." , even tens of thousands of times the firepower. In the Iraq War, an average of [-] bullets killed one person... But this, this... This machine is as accurate as the devil's scalpel," this is the American "In front of it, the gun is like a firecracker, just like a child's prank toy."

Rao Xin could no longer agree with the American's evaluation.

Rao Xin couldn't help scratching his head—it's true to be serious, but...whether it's a movie or a game, is it necessary to take the details so seriously?

As an author of science fiction, he can naturally realize what this kind of weapon with super lethal efficiency and precision beyond imagination means.Imagine if such a person in the video appeared on the earth with such a weapon, what would it mean?Within two seconds, he could clear all targets within a range of 5 square kilometers—and it was precise killing. This kind of massacre efficiency is more frightening than nuclear bombs.Before the automatic sighting system that is guaranteed to be locked and destroyed in [-] milliseconds, all aircraft missiles on the earth have become decorations. This is simply the perfect form of the US TMD (Theater Missile Defense Program).Even a small target like Feijian, which is only more than one meter long and more than ten centimeters wide, can be accurately locked, let alone these huge missiles on the earth.

After such an analysis, several people at the scene looked at each other in blank dismay—after an awkward silence, everyone burst out laughing—on such an illusory topic, they actually discussed a certain sense of reality, as if they were real aliens To appear on Earth and carry out aggression in general.

"For this weapon, the only possibility is that it has run out of energy and has temporarily rested," the American said. "The instantaneous power when it fires is almost equivalent to the ignition power of iter. Maybe the gap between launches is his weakness."

"This technical premise does not exist. Under the hypothetical technical background, the functional system of this weapon is an antimatter battery," Shen Changwen said. "The energy it stores is equivalent to the annual electricity consumption of a small country. Don't say Two seconds, even two hours, will not exhaust its energy."

Antimatter battery?How high is the budget for this project?

Funds are burning!

"Yes, anti-matter batteries. Now let's discuss the weapons we have, and these are not all from the earth," Shen Changwen opened another video channel, "First, let's take a look at this shield-like armor. Let me remind you that it It's an electromagnet."
