After Raphael sat down contentedly, another great wizard who was proficient in force field magic asked curiously.
"Your Excellency Linn, since you said that the distortion of space caused by mass causes the phenomenon of gravity, does that mean that only massive stars have this characteristic?"
"On this point, I think Mr. Harrov's theory of gravity has made it very clear. This phenomenon widely exists in everything." Linn replied calmly.
"Is there even a grain of sand or a stone?" Lidya raised her hands high and asked a question that most of the people present were very puzzled by.
"Of course!" Linn nodded and explained. "It's like putting an object into water. Even a grain of sand will inevitably push the water away!"
"Then why have we never felt the attraction brought by this so-called...space distortion?" Rohr couldn't help but stand up. This was also the question that confused him the most.
If gravity exists in any object, then it stands to reason that they also have it. Why are the sand and stones on the ground not attracted when walking on the road?
"That's because compared to our mass, the impact on space and time is too small. Even in front of a majestic mountain, its disturbance to space and time can be almost negligible. I am afraid that its attraction to you is far less than that of a person who happens to The gorgeous ladies passing by come higher!" Linn said jokingly.
Among the four fundamental forces, although the range of gravity is theoretically infinite, it is the weakest force.
This wonderful metaphor made Rohr dumbfounded, but he still asked another important question. "Since the influence of gravity is extremely weak, how can we be sure that it exists in everything?"
Only great wizards can barely feel the subtle changes in the curvature of space. For formal wizards, they can only rely on imagination to understand time and space.
"Sir Rohr, in fact, this is exactly the topic we need to discuss today!" Linn said and clapped his hands. Jonny, Alok and others immediately stepped forward and pushed a very delicate experimental device. Come up.
It looked like a steelyard for weighing heavy objects, but a two-meter-long steel wire was tied to the top, making it suspended in the air. A one-kilogram weight was placed on each end of the swing arm. Small round ball.
Are you ready to weigh in? The wizards at the venue were confused, but they quickly rejected this guess, because Linn asked Jonny and others to move two fifty kilogram iron balls next to the small ball.
Lin En then explained. "As I said before, universal gravitation exists in any object, and they will always attract each other. Although it is very weak, it is not non-existent. It just requires some special means to see this kind of disturbance."
"I think you haven't forgotten the previous pendulum experiment. You only need to use a slender wire rope to amplify slight disturbances. This torsion scale device also uses a similar method. I call it Micro deformation amplification method!”
According to the law of universal gravitation, the big ball will exert gravitational force on the small ball, and the entire T-shaped torsion scale will rotate at an angle in the direction of the big ball. The greater the gravitational force, the greater the twisting angle.
Then in turn, you only need to measure the angle of rotation of the wire rope, and you can calculate the force on both ends of the swing arm.
Under Linn's explanation, all the wizards were very interested in this small and exquisite device and stared at it non-stop.
"Did you see something? Peirce?" Alok looked at the small ball hanging on the swing arm. For a long time, he couldn't see any disturbance. He couldn't help but look at his companion and whispered. asked.
"Of course, just like what the professor said, the small ball is constantly being pulled closer under the gravitational force of the big ball..." Peirce nodded pretendingly, also always paying attention to the torsion scale on the high platform, but with Ai Like Locke, his eyes were sore and he couldn't see the slightest change.
But since the professor said this method is effective, it must be right!
The wizards in the hall were also looking at the balls. Except for Harrov, Raphael and a few others who could see the hanging wire ropes rotating slightly, everyone else was confused. A wizard Unable to help himself, he stood up and asked directly.
"Sir Linn, has your experiment started?"
Linn nodded and said casually. "Just one more minute and you'll see clearly!"
Seeing Lin En's affirmation, some impatient wizards on the field could only continue to wait.
The hands of the magic clock soon passed twelve o'clock!
The sun was already high overhead, and the rays were shining directly down.
At the same moment, Linn picked up an unusually small glass mirror and reflected the sunlight directly from the skylight onto the slender steel wire.
It was only then that many wizards noticed that there was also a strange circular mirror hanging at the middle end of the wire rope. After the sunlight hit the center of the circular mirror, it was reflected back to the scale on the opposite side.
"I saw it, it was moving, the light spot was moving!" Lydia shouted loudly.
In fact, there was no need for Lydia's reminder. This time, everyone could see very clearly that the light spot reflected on the scale was slowly moving to the right, slowly turning from zero to one.
"Could this be the effect of the earth's rotational force?" A witch suddenly interrupted in a shocking tone.
Luo Er and others immediately thought of this.
Yes, is it possible that the deflection force of the earth's rotation is affecting the slow movement of the ball, just like the previous pendulum?
Lin En didn't reply, and directly moved the big ball that was originally placed on the right side of the small ball to the left side. After a while, the light spot changed direction and began to shift to the left, slowly returning from one scale to zero scale. .
Seeing this extremely magical scene, everyone had no more doubts in their hearts, only shock!
Even the most demanding and cunning people cannot deny the existence of gravity.
After all, the light spot does not move randomly, but changes according to the position of the big ball.
So there is no doubt that this is definitely the effect of gravity!
It’s the attraction caused by the phenomenon of space distortion!
Compared to the other wizards who were marveling at the theory of gravity, Harrov paid more attention to the sophistication of the experiment itself.
The gravitational force of a fifty-kilogram iron ball is almost negligible, but Linn used his long swing arm to amplify this tiny influence once, and then amplified it twice through light. The subtle spatial distortion, which is usually not noticeable at all, was presented in front of them so intuitively!
Harrov couldn't help but sigh in the same way as Raphael. How could the other person's brain be so long that he could come up with such a wonderful idea.
