Chapter 158 Gravity
The new star formation was engraved on the left shoulder.

Cheng Jinzhou's heart moved slightly, and he gently moved it.

Different from the feeling of using the zero-level star array, he seems to be able to feel the connection with the starry sky in the dark. A transparent grid floats in front of him half-bright and half-dark. The interface is quite similar, but more unclear.

If he were an astronomer, he would definitely find that this is the astronomical map with Bactria as the center of the observation angle.

Cheng Jinzhou couldn't judge whether those gradually twinkling stars were distant stars, but he could tell at a glance that this inexplicably appearing grid turned out to be a dynamic three-dimensional figure, although its Z axis appeared in a non-proportional form , but it exists after all.

For the monkeys in the 17th century who didn't even understand Euclidean geometry thoroughly, it seemed even more miraculous that their star formations had three-dimensional images. No wonder few astrologers and cartographers were able to research brand new star formations , I am afraid that even if it is researched, there will be a lot of mistakes.

Although Mahron had handed over the bill to the priest of the church, he still stayed here and instructed loudly: "If you can vaguely see a star map, it means that the star god has recognized you. From then on, you can borrow The power of the Star God, in theory, can obtain energy from any cosmic body"

"I see a network of light and dark." Cheng Jinzhou kept moving his head up and down.

"That's right, that's the star map. It's not bad to be able to open the star map smoothly for the first time." Mahron praised Cheng Jinzhou in unproficient language.

"The question is how do I use it?" Cheng Jinzhou looked at the star map flashing in front of him, completely confused.

His anti-gravity star array is very simple. As a zero-level star array, it is usually used as long as it is turned on, and it will lose its effect when it is turned off.

The star array from the Holy Church is more advanced, at least it allows him to choose how much driving force, but from a mechanical point of view, it is just a few more gears.In addition, including changing the direction, etc., all need to be processed by manual foot movement, and cannot be controlled by the star array.

But the memory star array, as a first-level star array, is obviously much more complicated, so much so that Cheng Jinzhou doesn't know where to start.

Ma Helong looked at Xiao Cheng up and down with his blistered eyes, and said, "I don't know how you became a star warlock before. Others have learned the manipulation method, but they have no chance to become a level star warlock. You He became a dual star warlock, but he didn’t understand anything.”

When he said this, the two apprentice astrologists behind him lowered their heads even more.

It is really difficult to become a real star warlock.

To them, what seems so far away is like a lifelong goal - but in reality, if you can't become an Astromancer at the age of 40, your remaining chances are slim.

For every Apprentice Astromancer, time is so tight.

Ma Heron muttered twice to himself and continued to guide: "Do you see the black dot in the center of the entire star map?"

"I see." In the semi-darkness, there was always a black dot floating in the middle.

"It is the center, which is you. All the bright spots on the other star charts represent the celestial bodies of the universe, which are consistent with what you see when you look up at the starry sky. If you want to use the power of a certain celestial body, you must communicate with it... "

"How to communicate?"

Machron paused, coughed and said: "There will be suction of different sizes between different points. After you are proficient, you will have a general impression of the specific size of the suction. Now, first of all, you have to imagine that there is a force , connect the celestial bodies you want with yourself, and then transfer them to yourself."

When it comes to celestial bodies, when it comes to attraction, the first thing Cheng Jinzhou thinks of is gravitation—any two objects in nature are attracted to each other, and the magnitude of gravity is proportional to the product of the masses of the two objects, and the distance between them Inversely proportional to the second power of .

In other words, assuming that the star map that appeared in front of his eyes really represented the relationship between each celestial body and the planet, then there must be a gravitational connection between all celestial bodies. Machron's so-called power must be gravitational force.

It was the first time to speculate on the original power of astrologists. Cheng Jinzhou thought enthusiastically: If the different bright spots are celestial bodies and he is the earth, then there will be gravitational force between each point, and the gravitational force produced by the farther celestial body may be smaller. But objects that are farther away can be more massive.

The astrologers of this era only had a vague concept of gravitation, so they could only use star gods to explain everything and solve problems through experience - just like people have explained all uninformed natural phenomena for thousands of years. Same.

Newton's universal gravitation is so simple, but so bold, perhaps in this world, there is no gentleman who has such an imagination and the ability to prove it at the same time.

However, although the description of universal gravitation is so simple, its application is often complicated and frustrating.

Think about it, within the radius of the universe, in addition to the moon, the sun and several other planetary brothers and sisters, there are satellites of planets, comets, and other stars in the Milky Way, and stars in other galaxies farther away— Although many celestial bodies have a negligible effect on the earth, they still exist in reality.

Specific to the star map in front of him - Cheng Jinzhou is very sure that the star map is incomplete - the distance between the countless celestial bodies is guesswork, the mass of the celestial bodies is guesswork, and there are so many of them, no matter how clear and simple the formula is, Cheng Jinzhou used the method of elementary mental arithmetic tutorials, but he couldn't get the point for a long time.

Ma Heron was tired of waiting and said angrily: "You're too stupid. Let's try the sonic attack first. Think about the celestial body closest to you. Do you see a black line connecting the two?"

Cheng Jinzhou stopped his useless calculations, listened to his words and tried it, then shrugged and said, "I saw the black line."

"Okay, is the black line constantly fluctuating there, swinging up and down?"

"Yes."

"This shows that there are other celestial bodies that have an impact on the black line, and it means that you are not pious enough to the Star God." Ma Heron used a scientific method in the first half of the sentence, but the second half of the sentence mentioned religion, which is also the habit of the Holy Cult. He asked Cheng Jinzhou thought for a moment and then said: "What you have to do now is to think about adding reaction force to the black line and how to keep it straight. If the black line between the two stops shaking, then your relationship with this celestial body will be Even if the connection is successful, try more. How much reaction force to exert and in which direction, others can't teach you this. A good astromancer can be considered good if he can contact two or three celestial bodies in his lifetime."

Cheng Jinzhou raised his eyebrows and made the gravitational force between the two celestial bodies line up. Isn't this to calculate the influence of other celestial bodies on the gravitational force of the two celestial bodies?and cancel each other out?

He asked very puzzled: "How can I make it straight, I mean, how can I balance other forces without applying extra force.

"Then move yourself, move the black dot." Mahron was surprised by Cheng Jinzhou's quick response.

"Can the black dot move?" Cheng Jinzhou was stunned for a moment, but gravity is different.If anyone has the ability to move the earth, then it should be some kind of astromancer, or a demon king.

"Use your fingers."

Cheng Jinzhou hastily stretched out his hand, and flicked his fingers in front of him, which really made the black dot move.

The black line also fluctuated more and more violently.

"Just try to stabilize it." After saying this, Warlock Machlon packed up his things and ignored Cheng Jinzhou, who kept moving the black dots and had a great time.

The black spot can only move within a small range, but considering the relationship between distance and mass in the gravitational force, if the moving position is accurate, it is not impossible to offset the gravitational force generated by other celestial bodies.

After playing for a while, Cheng Jinzhou discovered after repeated attempts that there was a problem with the distance between these bright spots and black spots.

Seeing the unequal proportions of the Z axis, Cheng Jinzhou suddenly stopped.

It turns out that the proportions of the entire star map are confusing. One centimeter may represent 10 light years, or it may represent 10 kilometers, or it may even represent 10 meters.

No wonder astrologists use star charts every day, and they don't vigorously develop three-dimensional concepts, or consider the problem of universal gravitation.If the displayed ratio is chaotic, then they will not consider the problem of universal gravitation at all. When there is no necessary connection between mass and distance, he seems to be helpless.

Ma Helong slowly packed up his things. Seeing Cheng Jinzhou lost in thought, he finally smiled and said: "It is very complicated for everyone to use the first-level star array for the first time, especially when trying to combine two celestial bodies. It may take a long, long time to balance the black lines between them, so take your time.”

"Thank you very much." Cheng Jinzhou also laughed.

Perhaps because of the sincerity of his expression, Mahron forced a smile and said, "Did you see a very bright spot on the right side of your black spot?"

"I saw it."

"The brighter the point, the less interference from other darker points, you can try it first. It will be easier to stabilize the black line." The trick that Mahron said is also practiced by countless astrologists for countless hours came.

The value of civilization lies in inheritance.

Cheng Jinzhou immediately realized that the brighter point meant that it was a celestial body with a larger mass. Compared with a celestial body with a small mass, it was naturally easier to stabilize.

But looking at the star map, the brighter celestial bodies are basically in the outer circle. Although the specific proportion of the distance is unknown, it is certain that the outer celestial bodies are farther away.

The very bright dot, with only one next to the black dot, must have been a common celestial body for astrologists.

Cheng Jinzhou immediately drew between the two with his hand, and a black line was connected instantly.

And the degree of stability is obviously higher than the black line that was just connected casually.

Cheng Jinzhou looked at the floating star map and marveled. He didn't expect that in such a backward era, he could find something more advanced than the entire system of graphics.

But he doesn't know that not every astromancer can see a clear star map, which has something to do with the clarity of their thinking.

It is precisely because Cheng Jinzhou can understand things like universal gravitation that he can see very clear star maps. If he has no concept of astronomy, the light points he sees will not only flicker, but also the frequency will be very slow, making it impossible to judge.

Before Mahron Star Warlock left, Cheng Jinzhou hurriedly asked: "If the black line is not absolutely straight, can the star array be used?..."

"It's called a star line." Machron's old bubble eyes were helpless, and he paused for a while and said: "There is no need for an absolute straight line, but any bending will reduce the power. The more stable your star line is, the more stable the output of star power will be. , the longer the time. In addition, although the brighter point can bring more star power, it is also used by astrologists. If everyone uses the same celestial body as the source of star power, the star power obtained will be reduced, so you Try to grasp as many celestial bodies as possible, in case of emergencies.”

Cheng Jinzhou nodded gratefully, secretly stunned, using gravity as energy source, thanks to whoever came up with the idea, I don't know if it will interfere with the operation of other planets.

Mahron nodded, and walked out with the box in person.

Cheng Jinzhou continued to play with the little black dot with one finger.

Without knowing the mass and distance, balancing the universal gravitation is essentially a very good graduate thesis direction.

If we can study it clearly, let alone in a barren scientific soil like Daxia, even in the 21st century, it is possible to get the qualifications to stay in a Chinese university - if the research is more in-depth, it will be said in "Nature" It is not impossible to publish it.

Thinking this way, Cheng Jinzhou does not expect to be able to completely offset the gravitational pull of all celestial bodies on the star lines, but he can ignore most of the farther and fainter stars, thereby greatly reducing the difficulty of calculation.

As far as calculations are concerned, gravitation is a formula, as simple as a boiled egg.Cheng Jinzhou didn't know how many planets there were around the planet he was in, but considering that there were only 10 important celestial bodies around the earth, he simply selected a dozen bright spots around the black dot, and picked the nearest three Very bright light spots, guessed there.

He first assumed that the gravitational constant is constant, and then regarded mass and distance as unknown quantities, and the rest were all known quantities.

The whole process of trying is just to list a dozen quadratic equations in two variables, and then put them in the inaccurate three-dimensional geometry for experiments, to see the change of the position of the central black point and the change of the pendulum of the star line—although it cannot To get specific values, but you can get the relationship between the size, for Cheng Jinzhou, such a topic can only be regarded as difficult elementary mathematics.

After only seven or eight attempts, Dr. Cheng Da was able to do a good job, and the swing of the star line was also significantly reduced.

Although I don't know what the so-called stability requirements are, as long as the known quantities are continuously approached, there will always be a period of time when satisfactory results can be obtained.

Cheng Jinzhou was doing the paper work with ease, feeling very relaxed.

If other astrologists knew about his attitude, he would be so angry that he would vomit blood.

However, reality itself is what it is.

6.67259 was meaningless before Cavendish, but in 1798, the British physicist determined it as the gravitational constant with an extremely beautiful experiment - rated as the 10 most beautiful physical experiments in human history , countless physical practices seem to be given life.

Without knowing what gravitation is, the astrologists of Daxia cannot know the constant of gravitation, so even if they can think of the method used by Cheng Jinzhou, it is impossible for them to get the answer.

Because when G (the universal gravitational constant) is not an exact number but an unknown number, the dozen or so binary quadratic equations will turn into a dozen or so horrible ternary quadratic equations, trying to calculate the result with bare hands, It's not as realistic as fighting dinosaurs with bare hands, at least the latter has the possibility of being solved by intelligence.

……

Mahron staggered slowly on the hard rocky ground with an old man's style.

His wooden suitcase was never allowed to be touched by others. When he was young, this was a good habit that brought security, but when he got older, it became a tiring and bad habit.

From the room to the corridor, Mahron walked for four to five minutes, and the two apprentice astrologists patiently followed behind, not daring to help him.

Mu Yin and Tian Shimin came quickly from the main hall.As one of the five famous young masters in the capital, both of them are star warlocks from wealthy families. When they are in a good mood, they dare to break free even in the holy hall.Changing to other nobles, most of them have to weigh one or two.

"Machron star warlock, you haven't carved a star array for others for a long time, why did you come to the church today?" Seeing Lao Shuibaoyan from a distance, both of them stopped.Astrologists are often more popular than ordinary astromancers.

"It's the two elders. I'm here to imprint a young man with a star formation." Mahron's bubble eyes bulged.

"Is it a first-level star formation?" Tian Shimin asked curiously.

"Yes."

"So, Daxia is going to have more first-level star warlocks again? Why don't you see the guard of honor from the Holy Church and the Star Warlock Association?"

It is not easy to be promoted to Star Warlock. The Holy Temple and Star Warlock Association will naturally not give up the good method of exchanging worthless honor for trust.

Ma Helong laughed, put the heavy wooden box on the ground, pointed backwards and said, "It's a young man from Shaonan Cheng's family. He has been a two-star warlock for a long time, and now he has carved a first-level star formation. The level of the warlock is not considered to be improved."

Tian Shiguo said "ah?" Mu Yin's handsome face twitched, and he almost cried out, "Cheng Jinzhou?"

"Yes." Mahron didn't know the cause and effect, and didn't want to ask why Mu Yin reacted so much, so he lifted the wooden box shortly.

"When did he become a first-level star warlock?"

Ma Helong said a little unhappy: "Just now, Muyin Star Warlock. He is communicating with the star god, and he will be able to use the star formation smoothly in a few days."

With that said, he continued to walk forward.

"But, but..." Remembering not long ago, he declared that before Cheng Jinzhou could become a first-level star warlock, he would become a second-level star warlock, and Mu Yin's face turned red hot.

Tian Shimin glanced at his fourth brother with a funny face, patted him on the shoulder and said with a smile, "Since we know this first-level star warlock, let's say hello next time."

He was really afraid that the two of them would fight again.

Mu Yin has been known as a genius since he was a child, but now he is preempted by the country nobles in everything, not to mention the boredom in his heart, his face also changed from red to white to purple, and finally completely black.

Tian Shimin put an arm around Mu Yin's shoulder, turned him around and said with a smile: "Let's go, let's go back and play two more games."

"Boom!"

Like a thunderbolt, it exploded more than a hundred meters behind.

The three of them watched helplessly as a spherical shock wave blasted flying sand and stones into the fountain in the garden, and the splashed jets of water were like hailstones.

Now, even the gamblers in the main hall couldn't help but walk out of the door and look in the direction of the corridor.

Cheng Jinzhou walked out of the big hole in the wall in disgrace. While wiping his face, he apologized with a silly smile: "I'm sorry, I didn't expect the sonic attack of a first-level star to be so strong. Sorry, sorry, I'm not familiar with the star array yet..."

Ma Helong's eyes were as wide as goldfish, as if he wanted to squeeze out the blisters in his eyebags, and couldn't help but said: "He just started to communicate with the Star God, how is that possible!"

Li Zhong who hurried over from the inner hall happened to hear his words, and his eyes turned bright when he looked at Cheng Jinzhou.

In addition to the word count: In fact, I often read the book review section, and I have also seen everyone’s comments. I welcome everyone’s enthusiastic comments.
