Zhu Di said, and Zhu Gaochi commanded the two personal eunuchs who came with him to start the operation.

The process of the twist scale experiment is very simple, that is, put two small lead balls on the same horizontal plane of the equipment, and then let the two people put a certain weight of larger lead balls on both sides of the twist scale until the gravitational balance of the two small lead balls is broken, and then judge whether the experiment is successful by observing the movement of the light point reflected by the small mirror on the metal wire.

The key is to put the two large lead balls next to the small lead balls at an equal distance, but not touch them or get too far apart.

Zhu Gaochi's two personal eunuchs moved very lightly, under Zhu Di's gaze, constantly adjusting the position of the big shot put, after several attempts, they finally succeeded in achieving the goal of the two big shot put balls close to the small shot put, and maintain a state of balance.

However, as the two eunuchs moved away from both sides of the scale, the small lead ball immediately began to twist abnormally, constantly shaking back and forth, and the light points reflected by the small mirror on the metal wire also continued to move with the movement of the small lead ball.

Zhu Gaochi's heart sank, and he realized that there was something wrong with his plan.

Zhu Gaochi immediately called a few good-eyed Jinyi guards, let them observe the trajectory of the small shot put, and record the time of each movement and the position of the light point, after some research, Zhu Gaochi came to a conclusion: the trajectory of the small shot put is irregular, there must be interference factors, they need to redesign the experimental plan.

In other words, because of the interference factor of someone, the ground fluctuates, and the equipment rack in the darkroom trembles slightly, and the two small lead balls will shake abnormally.

But this is only a possibility, and perhaps there is something else to the truth. For example, this metal wire was originally very stable, but due to the influence of the air currents brought up by the two eunuchs during their activities, it became unstable, and the trajectory of the two small lead balls also changed......

In short, if you want to figure out what happened, you still need to find the "interference factor".

Then, Zhu Gaochi did a little improvement test, he instructed the Jinyi guards to fix one of the larger lead balls with a board near the small lead ball, and then did the same on the other side.

However, the two large lead balls were fixed, but the small lead balls did not move, as did the light points reflected by the copper mirror on the metal wire.

Seeing this, whether it was Zhu Gaochi or Zhu Di, they all felt that this so-called "gravitational" experiment was probably more than lucky.

After all, although it is not completely in accordance with the experimental steps mentioned by Jiang Xinghuo, two large lead balls, two small lead balls, metal wires, and small mirrors are all available, and the light spots have not moved.

Therefore, it is very likely that this so-called "gravitational force" does not exist at all.

Thinking of this, Zhu Di's Zhu Gaochi's mood is a little complicated.

As the ruling class of the Ming Dynasty, the two of them resolutely maintained the existence of imperial power, and of course they did not want any "gravitational force" and "heliocentric theory" to pop out and shake the traditional concept of heaven and man induction, so as to affect the imperial power.

But in the same way, there is also a subtle mentality, that is, the two of them are actually not willing to believe that Jiang Xinghuo, who has never made a mistake, will make a mistake this time.

The success or failure of the experiment is a direct reflection of the verification of this result.

Zhu Gaosui, the third prince next to him, watched it for a long time, and saw that his father and brother were silent, and couldn't help but say to Zhu Gaochi: "Big brother, what kind of reputation is this?" ”

"If you don't understand, don't care!"

"If you don't understand, don't care!"

Zhu Di and Zhu Gaochi said almost in unison, Zhu Gaosui shrunk his neck and hid behind his father.

Zhu Di clasped his hands in his cuffs and glared at his stupid son angrily.

The eldest can write, the second can be martial, and the third can eat.

Zhu Gaosui is more strict than when he eats when he doesn't eat, and he seems to be a little tight-lipped and reliable, but he is afraid that his brain is at the same level as his second brother.

When I was a child, the children of Xungui got together to go to school, and one of them was the first from the bottom and the other was the second-to-last.

When Zhu Gaoxu stopped reading, Zhu Gaosui became the penultimate forever.

Looking at the third brother who was sneering, Zhu Gaochi, who was a little impatient because of the failure of the experiment, felt a little annoyed for a while, and patiently explained to Zhu Gaosui for a moment.

"Big brother, although your method is good, but the big lead ball on the board is placed in a fixed place and does not move, isn't it impossible to achieve the effect you said? After all, any gravitational movement of the small shot put ball is caused by the big lead ball. ”

After listening to the eldest brother's explanation, Zhu Gaosui tried to open his eyes wide and said.

"What then?"

Zhu Gaochi stood for a long time, and at this time, he was a little impatient, and he became a little dizzy.

Seeing this, the two eunuchs who had served him for many years hurriedly stood up left and right, and then a brocade guard sent a chair for him to sit down and rest.

Zhu Gaochi also pointed to the two personal eunuchs a little helplessly and said: "They are already the most dexterous, they usually walk and do things lightly, Rao is so, as long as people go in, the unflowing air in this dark room will be disturbed, and the ground will also have a slight vibration, as long as there are these movements, it will not be accurate, and if you change to other brocade guards, I am afraid that the movement will be greater." ”

"So what should I do?" Zhu Gaosui said, "Is it just left to be left alone?" ”

Zhu Gaochi sighed and said with a wry smile: "Let me think about it first, and then try again later, if it doesn't work, I'll think of other ways." ”

After Zhu Gaochi finished speaking, he waved his hand, and the two eunuchs hurriedly retreated, walked to the dark room, and waited for the order of the eldest prince before continuing to operate according to the previous steps.

Zhu Di was pacing slowly beside him, his face was slightly cloudy, and he was obviously worried.

After a while, Zhu Di suddenly stopped, looked at Zhu Gaochi and said, "Mr. Jiang at that time, was the step he did not be like this?" How to deal with these two big shot puts? It doesn't seem to be a human to get it. ”

Zhu Gaochi nodded and replied: "Back to my father, what Mr. Jiang said at that time was to put two smooth guide rails, so that the two large lead balls slowly arrived at equal distances on both sides. ”

"Then why not do it?" Zhu Di looked at his eldest son and asked.

Zhu Gaochi explained: "I have tried before, but I can't do it, as long as there is a sloped guide rail, because the weight of the lead ball is too large, it will cause vibration to the balance instrument with metal wires and small mirrors hanging in the middle, and this vibration is even greater than the movement of people lightly." ”

"What about the ones with no slope?"

As soon as Zhu Gaosui couldn't help but ask, he knew the result.

"There is no slope, the big shot put does not slide at all." Zhu Gaochi replied.

Hearing this, Zhu Gaosui couldn't think of any good way.

Since there was nothing good for them, they had to continue to try to manually carry the large lead ball again.

The two eunuchs even took off their somewhat cumbersome robes and shoes, wore their middle clothes barefoot, and held two large shot puts, which they placed next to the small lead balls leisurely.

The father and son, who were observing outside the dark room, couldn't help but look intently at the results of the second experiment.

After all, these two big lead balls, in fact, are not shaking the mirror, but the imperial power!

The two eunuchs picked up the big lead ball with both hands, stretched it forward softly and with all their might, then adjusted the angle to the wooden board that was cushioned, and began to use their arms as a fulcrum to hold the big lead ball and move it to the small lead ball.

Although this method is more labor-intensive, it is better to be safe, after all, the small shot put is fixed, and you only need to try your best to keep the large shot put balanced.

However, in this process, the two eunuchs had to be careful about their surroundings while moving the large lead ball, so as not to let the large lead ball be in the wrong position or collide with the metal frame, in case of accidents—an operation that was indeed a great test of arm strength and patience.

Zhu Di and Zhu Gao stared at the changes in the mirror and the lead ball.

The large shot put ball was placed in the pre-drawn position.

However, the two small lead balls remained unmoved.

The two eunuchs were not reconciled, and once again pushed the big lead ball with their arms, and moved it slightly to the small lead ball by two inches, this time there was finally a little movement.

I don't know if it was uneven, but the result of the efforts of the two eunuchs was that the small lead ball on the metal frame moved, swirled in its original position, and rubbed against the metal wire and the mirror, making a fine and harsh sound, but the experiment still had no results, obviously did not produce the slightest "gravitational force".

This made Zhu Gaochi, who presided over the experiment, a little discouraged.

Zhu Gaochi remembers clearly that Mr. Jiang said that this experiment was very simple, but it was so difficult for him to do it himself.

If the forces on both sides of the large lead ball cannot be balanced, it is estimated that it is difficult to truly test the gravitational fluctuations of the small lead ball.

Zhu Di saw that the two experiments failed, but he was relieved.

There is no "gravitational pull" of Rausch, which is better for him.

After all, if "gravitational force" does not exist and the "heliocentric theory" cannot be explained, then the traditional concept of celestial and human induction will not be shaken, and imperial power will not be threatened.

At this moment, Zhu Gaosui frowned and pondered for a long time, then suddenly raised his head and said, "Big brother, father, I have an idea." ”

"Oh?" Zhu Di looked at his youngest son in surprise, "Let's talk about it." ”

Zhu Gaosui scratched his head and said: "I see people building houses, sometimes they tie ropes and rope wheels between the second floor and the first floor, and hand over the waste wood and the like on the second floor directly. The same goes for the first floor if you want to transport things up. Why don't we use a rope wheel? In this way, as long as the position is aligned, it will avoid human power causing the ground and air disturbance in the dark room. ”

"Rope wheel?"

"Yes."

Zhu Di frowned after hearing this, showed a smile, and said, "According to the third child's method, you can hang a rope wheel on the beam of the dark room to fix it, and then pull the rope at the place where the holes are opened on both sides, so that people will not go in, and the position is also accurate, just pull the knot in a position, and touch the fixed plank below, it will naturally be able to stabilize it, if it is not successful, then it means that this Raushzi's 'gravitational force' does not exist at all." ”

Zhu Gaochi also held up his two thick fingers, compared a "V" shape and said: "You can also nail it with two wooden boards, just enough to jam the big lead ball." ”

"Go for it."

Zhu Di waved his hand, and the brocade guards hurriedly went down to execute.

And Zhu Di, father and son, also began to wait for the results of this last experiment.

If this experiment still fails, then it proves that Jiang Xinghuo was wrong for the first time

But could Jiang Xinghuo really make a mistake?

Zhu Di's heart suddenly jumped out of such a question that surprised him.
