[Light Needle (Level 3): Accelerate a gram of 'needle tip' to 0. times the speed of light, and use the mass multiplication effect to generate 13.95 trillion trillion joules of impact energy when it collides with a massive object. Exchange for the required reputation
:500.】
Zhao Yu looked at the weapons that appeared in the redemption list, scratched his head, and was a little confused.
I can understand every word in the introduction, but when put together, I don’t understand it at all. The last paragraph generates 13.95 trillion trillion joules of impact energy, but I don’t know how powerful it is.
The only thing I know is that this light needle is a weapon only available to level 3 civilizations.
Fortunately, if you encounter something you don’t understand, you can ask someone.
When Zhao Yu was about to ask Colonel Chu what Joule was, he suddenly stopped again.
It’s hard to explain how the weapons came from just asking so rashly.
Simply being patient, Zhao Yu returned to his residence as usual after the matters here were settled.
After staying for a while, I excitedly found Colonel Chu.
"Sir, what's the happy news?!" Colonel Chu asked curiously when he saw Zhao Yu hurried back not long after he left, with a look of joy on his face.
"Pangu civilization has passed on new weapons!"
"What!?"
Colonel Chu's face lit up with joy and he quickly asked: "What kind of weapon is it?!"
Zhao Yu read out the introduction in the reputation list and asked: "Do you know how powerful these 13.95 trillion trillion joules are?!"
"13.95 trillion trillion trillion joules?!"
Colonel Chu was shocked. This number was beyond imagination. He quickly took out the banknotes and started counting.
"The formula for impact energy is E=1/2mv^2, E represents the impact energy, m represents the mass of the impacting object, and v represents the velocity..."
"The speed of light constant c=m/s, the weapon description mentions the mass increase effect..."
Colonel Chu paused for a moment, recalled something, and then calculated again, "The mass increase effect means that the moving mass of matter follows the mass-velocity relationship. The calculation formula is M=m/√[1-(v/c)^2]
..."
"..."
"The energy released by the explosion of one ton of TNT is 4.18*10^9 Joules..."
"The energy required to destroy a blue star is 3/5xGM^2/R = 6.299x10^32 Joules, where G gravitational constant, M, R are the mass and radius of the earth..."
"The energy generated by the impact of the light needle is 1395x10^32 joules..."
Colonel Chu's eyes showed shock, "The energy generated by the impact of this light needle is enough to destroy the Blue Star 200 times!"
But soon, he frowned again, "According to this calculation, the power of the light needle impact is actually not as powerful as the particle black hole collapse bomb..."
Colonel Chu explained a lot, and even rambled on while calculating, as if he was telling others.
But Zhao Yu only understood the last two paragraphs, which was that the light needle impact could destroy the Blue Star 200 times, but its power was not as powerful as the particle black hole collapse bomb.
This made him a little curious and asked: "How to say?!"
Colonel Chu said with mixed emotions: "The impact of the light needle can be regarded as a physical attack. The collapse of the particle black hole is related to gravitational waves. There is no research on this aspect. From the feeling, the gravitational wave attack is more advanced and somewhat difficult to defend against..." Zhao Yu asked doubtfully: "Can this light needle be used for defense?"
"A physical strike, according to the description of the light needle, must hit an object with mass to generate such a large amount of energy. Before the impact, it is just a needle moving close to the speed of light..."
Colonel Chu explained: "The particle black hole collapsed and covered a range of 500,000 kilometers. Within this range, we have almost no way to escape and no way to defend..."
"As for the light needle strike, it is known that the speed is close to the speed of light. Although it cannot be detected, the speed of light is 300,000 kilometers per second. According to the data analysis in previous wars, our laser defense system can only operate within 30,000 kilometers of the warship.
Only then can you hit the target 100%..."
"This means that as long as we are 30,000 kilometers away from the enemy ship, keep dodging, and do not follow the original trajectory, we have a high probability of avoiding the light needle strike..."
Before he finished speaking, Colonel Chu himself paused again, shook his head and said: "No, it can't be calculated like this..."
"In light needle strikes, the carrier is a 'needle tip' with a mass of only one gram. It is absolutely impossible for existing gravitational wave detectors to detect..."
"At the speed of the light needle, other types of detection equipment cannot detect it. When these devices can detect the light needle, it means that an impact has occurred..."
"Coupled with the vacuum environment in the universe, the light needle strike has almost unlimited range..."
"Unless it encounters an obstacle and collides with it in advance to release energy, before that, the light needle can keep moving forward at the speed of light and never fail..."
Colonel Chu became more and more excited as he talked, "Infinite range is only theoretical. In fact, there are many massive objects flying around in the universe..."
"Even if there are countless unknowns in the universe, within the galaxy, it is possible to calculate the obstacles within the entire universe and avoid them in advance to achieve ultra-long-distance light needle strikes..."
"Even if the detection capability and computing power are sufficient, the optical needle can achieve cross-galaxy strikes..."
"Also, according to the introduction, the mass of this light needle is only one gram. Does that mean it can be emitted on a regular basis?!"
He said excitedly: "The particle black hole collapse bomb requires a warship as a carrier and is difficult to use without the warship. It is extremely conspicuous and its shortcomings are also very clear. Each warship must self-destruct before it can be used..."
"But if the light needle strike can be fired continuously like a kinetic energy cannon, it is simply unimaginable..."
Each one has only one gram, and almost no means can detect it, and the detection is the attack method. If it can be launched on a large scale, hundreds of millions of them can be fired at once. Such a density is not to mention 30,000 kilometers.
, even if it’s 3 million kilometers, it’s hard to escape.
Moreover, the most terrifying thing is that this light needle strike has almost 100% hit when faced with a fixed target.
Because the enemy will not notice that the light needle is already on the road, or even know that the attack has been sent out.
"Sir, this weapon is very good. If operated properly, we can even launch it directly from the solar system to Proxima Centauri and kill those aliens..." Colonel Chu was very satisfied. Fortunately, the Pangu civilization was the mother civilization of the Blue Star civilization.
Otherwise, if you encounter this kind of dilemma, you may be waiting for death.
There is a Level 3 civilization in the Proxima star system next door, and the other party may also have this kind of method that can quietly destroy a civilization.
"To launch from here to Proxima Centauri, even if it is a light needle, it will take 4 years to get there?!" Although Zhao Yu doesn't understand those data formulas, he still understands the common sense units of light speed and light years.
"That's right!"
Colonel Chu nodded and said: "So, how to make the light needle reach Proxima Centauri smoothly is the key. This requires that the light needle cannot touch any objects with mass within these four years, not even one gram..."
"This seems a bit difficult..."
Zhao Yu frowned. He had been studying astronomy these days. He knew that there was a lot of cosmic dust floating in the universe.
Colonel Chu also thought of this and quickly said: "Sir, do you know the minimum triggering mass of this light needle?"
"I don't know..."
Zhao Yu shook his head. The light needle has not been redeemed yet. He only knows the introduction of the reputation redemption list. What is the specific situation? We have to wait until it is redeemed.
Colonel Chu nodded slightly, gradually calmed down, and analyzed: "The size of most cosmic dust ranges from ten to three hundred microns, with an average mass of one hundred and fifty micrograms. As long as the minimum trigger mass of the light needle is greater than five hundred micrograms, we can strike across galaxies."
The difficulty will drop significantly..."
"This is also difficult..."
Zhao Yu tugged his hair and said: "Four light years is equivalent to a distance of 37 trillion kilometers. The dust in the universe is always moving..."
"If we want to strike across galaxies, we need to find a route that allows the light needle to pass smoothly within such a light range, and we also need to calculate the trajectory of these cosmic dust..."
"In addition, we don't seem to be able to detect all the cosmic dust between the solar system and the nearby galaxy..."
"It's really difficult..."
Colonel Chu nodded, and then said: "But it is difficult to return, as long as you find a way to overcome it, there is always a chance..."
"In recent years, we have received a lot of light signals from the universe, and we can determine the location of obstacles based on their trajectories..."
"Every second of light signals can draw a rough map of the universe's star field. By integrating the light signals of all time periods, it should be possible to determine the trajectory of cosmic dust..."
This is like adding a time dimension to minesweeper. It changes every second, and you need to judge the trend of the next second based on the situation of the previous second, or judge the trend of the previous second based on the next second.
Zhao Yu was stunned, "This project is not small. How many layers of the universe star field map need to be constructed based on the light signals received over the years?!"
In seconds, there are 31.53 million seconds per layer of the universe star field map in a year. After so many years, the minimum number of universe star field maps that need to be constructed is counted in billions.
This is just the simple work in the early stage. The most complicated part is to find the patterns among the billions of star field maps.
The most terrifying thing is that the world is so large, and countless light signals are received every year. Even if we only count the recorded ones, it is an unimaginable calculation.
Colonel Chu nodded and said: "It is almost impossible to achieve this by relying on human power. We can only rely on computers..."
"Sir, there should be a super host at your moon base, right? With its computing power, there may be hope..."
Uncle Da?!
Zhao Yu was startled for a moment, then nodded and said: "I'll send your idea back and see if there's any way to calculate it..."
"You just keep watching here, and I'll go see when the light needle can be built..."
After saying that, Zhao Yu returned to his room.
At this moment, the system prompts sounded twice more.
[Mihui Civilization (Level 1): 10.0%, activate 10% of nodes, gain 100 reputation.]
[Skybat Civilization (Level 1): 10.0%, activate 10% of nodes, gain 100 reputation.]
【Reputation:700】
[Current number of redeemable technologies: 1]
"Would you like to save more and look at other technologies?!"
Zhao Yu was a little excited. The light needle exchanged for 500 reputation is so powerful. Will more reputation lead to more powerful technology?!
But this kind of thing is uncertain. If the next convertible technology requires too much reputation, it may delay the war.
Now, according to Colonel Chu's plan, the limit of their delay is three to five years.
If we exchange the light needle now, calculate a feasible route as soon as possible, and launch an attack on the Proxima Galaxy, maybe the crisis will be completely resolved in four years.
After hesitating for a while, Zhao Yu finally decided to exchange the light needle.
[Do you want to spend 500 reputation to redeem the third-level civilization technology: Light Needle?]
"Yes!"
[Please select the production line placement location.]
Brush!
After a red light flashed in front of my eyes, the transparent star map in the solar system appeared in my mind again, as well as the required location.
Zhao Yu opened his mouth involuntarily, with a shocked look on his face.
“You actually need such a big place?!”
What he didn't expect was that the required placement location for the optical needle production line was so large that the entire base could not accommodate it.
You know, the base he is staying at now is a fragment of Pluto with a diameter of two hundred kilometers.
The red block for installing the optical needle production line did not indicate clearly how much area was needed. Zhao Yu could only roughly judge that the length of the red block was more than a thousand kilometers based on the length of the base.
This means that he has to find a place with a length of at least one thousand kilometers to place a production line for optical needles.
"This..."
After searching a lot, there was no spacious enough space on the moon to place it, so I finally found two suitable places on the Blue Star.
One is the newly planned scientific research area in the Blue Star transformation plan, and the other is the mass-produced grain growing area.
"What a coincidence..."
Zhao Yu also didn't expect that what he had done easily before would actually come in handy today.
He was about to press the placement button in the scientific research area when he suddenly froze again.
"I have to tell Uncle Da about this..."
He is worried that there will be ignorant robots that will destroy the production line.
This thing is a technological product of level 3 civilization. It cost 500 reputation to redeem it. If it was destroyed like this, it would be over if it couldn't be repaired.
To be on the safe side, Zhao Yu recorded a video and narrated his plan to install the optical needle, and asked Uncle Da to take protective measures to ensure the smooth installation of the optical needle production line.
In addition, Zhao Yu also explained what he had previously discussed with Colonel Chu, regarding the idea of using light needles to attack enemies across galaxies.
Let Uncle Da see if there is any way to build a set of star maps that can illuminate the space between the solar system and the Proxima Nebula.
After recording the video, Zhao Yu sent the content back to the moon.
Coincidentally, Uncle Da also sent a routine report message.
Zhao Yu looked through it and found that it was nothing major. There were only two points of useful information.
First, Uncle Da has accumulated 500,000 warships and has sent them to the front line at once for him to prepare to receive them.
The second one is related to the humans on Bell's Comet, which mentions that Uncle Da discussed with Penguin executives to design a reward mechanism.
Moreover, this reward mechanism is used very well. People who used to have nothing to do all day long went to the virtual world and began to learn to control the spacecraft.
Human society has also begun to develop a culture of worship that is spontaneously formed among the people, such as whoever can get a spaceship pilot's license will have priority in mating.
Seeing this, Zhao Yu couldn't help but nodded with satisfaction, "If this continues, we will soon be able to form a fleet controlled by humans..."
After all, there are hidden dangers in the robot fleet. It needs to be restricted by an absolutely loyal host. It cannot fight independently remotely, otherwise there is a risk of defection.
Therefore, it is imperative to form a fleet controlled by natural persons. Even according to the current situation, this fleet may not be used, but it cannot be left without it.
