Chapter 131 - 131 Formula
[Huo Gu, the thing you built is the one that seems to be very powerful... Er... What's its name?]
[Oh, by the way, it's called 'E=MC^2'.]
From its God's perspective, it is observing the metal bodies that are gradually speeding up in the epdochina magnetor.
One kilogram of metal will surround the planet's equator for two weeks, and then be launched from the remaining magnetic orbital giant. At this time, the initial speed of a small shell with a kilogram mass is more than 90% of the speed of light.
Huo Gu has built a complete large sublight-speed weapon this time, which is not often mentioned even in science fiction or novels.
Huo Gu relies on radio pulses to target in space. Aliens do not rely on radio pulses for positioning, but the essence is the same. Both use light-speed particles to receive feedback after hitting the target to obtain the location information of the target.
However, in the face of sub-light-speed shells, the limitation of this positioning method has become very large. Because the movement of the shell is close to the speed of light, the shell will follow behind the reflected radar beam. When the radar receives the beam carrying the position information of the shell, in fact, the shell is very close to the position of the ship, which is basically If you don't have time to make effective evasive measures, you can only resist.
This is also the reason why the radar of the alien fleet failed to find the 'micro-blue thing'. On the one hand, it is indeed because of its small size, but on the other hand, it is its own sub-light speed.
"Miao, E=MC^2 is a formula, not the name of an object..."
Huo Gu complained speechlessly and then explained.
"This formula expresses what form of existence a mass object will become after its speed is increased to the speed of light, and then the relationship between mass and energy."
The wrong understanding did not make me feel embarrassed. The mind was not as complicated and diverse as human beings. It calmly accepted its cognitive mistakes.
After thinking about it, he organized the confusion in his heart into a question and asked Huo Gu.
[I remember you said before that the motion formula of an object is Ek=1/2MV^2. Why does the formula become E=MC^2 after a mass object accelerates to the speed of light?]
"If I knew this, would I still call them to learn physics? It's you, aren't you better than me in that? Why do you ask me this?"
Hearing Wei's inquiry, Huo Gu felt that he had a big head. How could he know this kind of thing? The physical formulas he uses now are just the accumulation of knowledge he memorized in high school.
At the beginning, it was all to cope with the college entrance examination, but I was not in the mood to delve into why it was like this.
He mistakenly thought that Huo Gu didn't understand the questions he asked, so he emphasized one side of the key points.
[The principle of the thing you built is quite simple. It is nothing more than using the electric field to push the metal body. As the length increases, the faster the metal body will accelerate. I just don't understand how the two formulas you mentioned before are converted. Where is the half of the kinetic energy formula? Why isn't it in E=MC^2?]
"Don't ask me. I haven't studied this specifically. Since I'm so curious, I might as well study it by myself, let Yongsue teach you mathematics, and then deduce the formula by myself."
[But Huogu, aren't you able to use the formula freely? Why don't you understand?
"Who told you that if you don't understand, you can't use it? Have you never heard of 'moving a hard cover'?
"...No, you really haven't heard of it."
While Huo Gu muttered to himself, he was attracted by other things.
I saw it asking Huo Gu on the channel.
[Huo Gu, have you noticed?]
Huo Gu was pulled back to his mind from his thoughts. This beginningless sentence made Huo Gu a little confused. He roughly examined all his senses.
No abnormality was found.Wrapped in doubt, Huo Gu asked Miao.
"What did you notice?"
[In the direction of the enemy, many objects are approaching at high speed, but there is still some time before they come to our position.] historical
"What?!"
Hao Gu's answer made Huo Gu alert. He didn't have the relaxed attitude like Wei. Huo Gu understood the seriousness of the problem. The enemy is an opponent who needs people on earth to rely on the unresive 'myths' to describe and understand.
Huo Gu has thought more than once that if these aliens are not their own opponents, but the earth's civilization, what are the chances of winning the earth's civilization?
The Tianyan system began to search for the objects mentioned by ming. Huo Gu needed more accurate information, from which he inferd the true face of those high-speed objects, and then achieved targeted defense.
But as a result, nothing was found between the alien fleet and Huogu, and there was no echo signal of the radio pulse.
"Where is it? Why didn't I see anything?"
Even if it was a full-power celestial eye system, Huo Gu still failed to find those objects approaching at high speed. He felt that he was joking with it.
However, he was sure in his tone, and there was no joke at all.
[Maybe it's because it's too small. After a while, you can see it.]
In this way, Huo Gu maintained his doubts for more than a dozen days and nights...
At this time, the Sky Eye finally observed a large group of high-speed approaching objects, which looked geometrically long shuttles, and looked like some kind of shells with special abilities in online games.
In accordance with the principle of caution, Huo Gu decided to destroy these objects. Based on this idea, the live ammunition was fired as an interception.
However, a scene that Huo Gu never expected happened.
"Dodge it?"
In Huo Gu's observation, those individuals who used to intercept shells were dodged one by one. It was also because of this that Huo Gu's speculation that these objects were like shells was overturned.
Is it a missile?
Huo Gu thought of the scene in the last battle where a whole meteorite that was not less than Mount Everest could be directly turned into powder.
Huo Gu, who was in pain, decided to use a large number of bullets to encircle and intercept.
"Let me see how you hide this time."
In the face of overwhelming metal bullet screens, Huo Gu was confident that those things could not be avoided. As Huo Gu expected, they did not come, but this did not mean that the bullets could play an interception effect.
Through the observation of the heavenly eye, Huo Gu only felt that the figure of those unknown objects had become blurred. Just when he was puzzled, he broke the truth that caused this situation.
[Huo Gu, the things you released seem to be useless. They were all shattered when you touched those objects.]
"Shmash? How much is it smashed?
[Uh... It's probably similar to the vaporization reaction after high temperature.]
