Chapter 160 Calculation of gravitational constant by mirror reflection
After Raphael sat down satisfied, another great wizard who was proficient in force field magic asked curiously.
"Your Excellency Lynn, since you said that the phenomenon of gravity is caused by the distortion of space caused by mass, is it true that only massive stars have this characteristic?"
"This point, I think Mr. Harov's theory of gravity is very clear. This phenomenon exists widely in everything." Lynn replied calmly.
"Is there a grain of sand and a stone?" Lydia raised her hand high and asked a question that most of the people present were very puzzled.
"Of course!" Lynn nodded and explained. "It's like putting an object into the water, even if it's a grain of sand, it will inevitably push the water away!"
"Then why have we never felt the attraction brought by this so-called... space distortion?" Rolle couldn't help standing up, this is also the question that puzzled him the most.
If gravity exists in any object, 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 quality, the impact on time and space is too small. Even in front of a towering mountain, its disturbance to time and space can be almost negligible. I'm afraid it is far less attractive to you than a coincidence The gorgeous ladies passing by are even higher!" Lynn said jokingly.
Among the four fundamental forces, although the range of action of gravity is theoretically unlimited, it is the force with the weakest effect.
This wonderful metaphor made Luo Er a little 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.
"Your Excellency Rolle, in fact, this is exactly the topic we need to discuss today!" Lynn clapped his hands while talking, and Johnny, Eloke and others immediately stepped forward and pushed a very delicate experimental device away come up.
It looks like a steelyard for weighing heavy objects, but a two-meter-long steel wire is tied to the top, making it suspended in the air, and a one-kilogram weight is placed on each end of the swing arm. Small balls.
Is this ready to weigh in? The wizards at the venue were confused, but they quickly rejected this guess, because Lynn asked Jonny and others to move two 50-kilogram iron **** to the side of the small ball.
Lynn explained. "As I said before, the universal gravitation exists in any object, and they will always attract each other. Although it is very weak, it does not exist. It just requires some special means to see this disturbance."
"I don't think you have forgotten the previous pendulum experiment. You only need to use a slender wire rope to multiply the slight disturbance. This torsion balance device also uses a similar method. I call it Micro-deformation amplification method!"
According to the law of universal gravitation, the big ball will generate gravitational force on the small ball, and the entire T-shaped torsion balance will rotate an angle toward the direction of the big ball. The greater the gravitational force, the larger the twisting angle.
Then in turn, only need to measure the rotation angle of the steel wire rope, and also can calculate the force on both ends of the swing arm.
Under Lynn's explanation, a group of wizards were very interested in this small and exquisite device, staring at it non-stop.
"Did you see anything? Pierce?" Ai Luoke stared at the ball hanging on the swing arm, and couldn't see any disturbance for a long time. asked.
"Of course, just like what the professor said, the small ball is being pulled closer under the gravitational force of the big ball..." Pierce nodded pretendingly, and was also paying attention to the torsion balance on the high platform all the time. Similarly, his eyes were sore, and he couldn't see the slightest change.
But since the professor said that this method works, it must be right!
The wizards in the hall were also looking at the spheres. Except for a few people such as Harov and Raphael who could see the hanging wire rope turning slightly, everyone else was at a loss. A wizard Standing up uncontrollably, he asked directly.
"Your Excellency Lynn, has your experiment started yet?"
Lin En nodded and said casually. "Just wait another minute, and you'll see clearly!"
Seeing Lynn's affirmation, the impatient wizards had no choice but to wait.
The pointer of the magic clock soon passed twelve o'clock!
The sun is already high above the head, and the sun is shining directly down.
At the same moment, Lynn picked up an unusually small glass mirror, reflecting the sunlight directly from the skylight onto the slender steel wire rope.
Until then, many wizards noticed that there was also a strange round mirror hanging from the middle end of the steel wire rope. After the sunlight hit the center of the round mirror, it was reflected back to the scale on the opposite side.
"I saw it, it's moving, that spot of light is moving!" Lydia shouted loudly.
In fact, Lydia didn't need to remind her. This time, everyone could see very clearly that the light spot reflected on the scale was slowly moving to the right, from zero to one scale.
"Could this be the effect of the Earth's rotation?" A witch interrupted with a sudden, unsightly voice.
Roll 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 pendulum before.
Lin En didn't answer, and directly moved the big ball that was originally placed on the right side of the small ball to the left. After a while, the light spot changed direction and began to shift to the left, from one scale to zero scale slowly .
Seeing this incomparably miraculous scene, there was no doubt in the hearts of the people, and the only thing left was shock!
Even harsh and tricky people cannot deny the existence of gravity.
After all, the light spot does not move randomly, but changes with the position of the big ball.
So there is no doubt that this is definitely the effect of gravity!
is the attraction produced by the space distortion phenomenon!
Compared to the other wizards who were marveling at the theory of universal gravitation, Harov paid more attention to the ingenuity of the experiment itself.
The gravitational force possessed by a fifty-kilogram iron ball is almost negligible, but Lin En used his long swing arm to amplify this tiny effect once, and then amplified it a second time through light to achieve The subtle space distortion that is not even noticeable in ordinary times is presented in front of them so intuitively!
Harov couldn't help expressing the same emotion as Raphael, how did the other party's brain grow so that he could come up with such a wonderful method.
