"That's right. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoIf the object here can be identified as an extra-dimensional 'shadow', then this should also be relevant to the understanding of the existence of dark matter. ”

Bai bit put the camera outside, came back and said "I see", and nodded.

Once you've prepared your equipment and opened the shutter, you can just leave it alone until the time is up. So there's no need to stand next to it.

"The presence of mass distorts space, and this distortion is observed as gravity. However, if space is distorted for reasons other than mass, gravity-like phenomena should occur even if there is no matter there. ”

"Space warp is gravity? What's going on?"

Facing the silver-haired girl who suddenly came over to talk, "That is to say, this is the case" Yang Ming actually began to explain kindly.

After he pulled out the rubber non-slip mat next to him, he asked the white bit, Urubata and others next to him to help tighten one side and make its surface smooth.

"Go further there, taut it...... That's right, yes, yes. ”

Kurata and the others also found it interesting and gathered around the mat. The photographer was urged by Kuribayashi to start shooting.

"Is that okay? Think of this as a space. As can be seen, it is in a flat and undistorted state. However, if there is a substance with weight present here. ”

Yang Ming said, casually picking up the grenade that Itami hung on his chest and placing it on it. Itami, who had taken the grenade, was shocked with an "ah", but the grenade's tab was not pulled out, so he left it at that.

"Doesn't this rubber mat bend in response to the mass of the object?"

In fact, the rubber pad only slightly dented that part of the weight of the grenade.

"The phenomenon that arises from this depression is the falling of objects. This depression is the 'gravitational force'. ”

After listening to Yang Ming's explanation, Nanami Kurithayashi tilted her head. She didn't seem to quite understand. But Leilai's eyes lit up and she nodded as if she realized something.

"The phenomenon of objects falling downward is due to this distortion...... inclination. In that case, if there is mass, gravity will inevitably occur regardless of its mass. ”

"Hmmmm. That's right. ”

This is the moment when the scientists of this world are taught the law of gravitation.

Yang Ming took the marbles out of his pocket and threw them on the rubber mat.

"Professor, why do you still have this with you?"

"Pachinko is science. Sooner or later, I'm going to have to figure out the winning equation for this thing. ”

"Pachinko used to be a science club, but 40 years ago, when you were still using a handle to play pinball and aim at tulips, right? ”

"What a guy who doesn't understand romance. ”

The silver marble didn't care about his conversation with Urushihata, it rolled slowly on the surface of the rubber mat. Then they are attracted by the bend (dent) caused by the grenade, and finally hit its surface with a single blow.

"When an object exists, it distorts space...... So depending on its mass and size, it is also possible to make a hole in the space?"

Hearing the question raised by Leilai's eyes lit up, Yang Ming smiled.

As usual, Ushibata began to observe Relai, and said, "This little girl is very young, but she is quite smart. There is no student with such understanding today. Something like that.

"I said, I said, can this girl take it back?"

When asked, Itami replied, "I just said yes." Don't look at her like this, she's a scholar of this world, and she's also a magister. However, it is also very troublesome to study abroad, so you can't go there in a day or two. ”

"Roar, a scholar of this world and a magister, the old man has been interested in magic before. Then let's go to my husband's laboratory to study abroad?"

"Professor Yangming, you are so cunning. I fell in love with her first. ”

"It doesn't matter who comes first and who comes last. It depends on her fit for the lab. ”

Yang Ming engaged in this conversation as he took the grenade and marbles off the rubber mat.

"Then, if there is nothing, it will be flat and undistorted, and this is the normal way of space. Now suppose that space is distorted for some reason......"

Yang Ming said, reaching under the rubber mat, grabbing and pulling down from below.

Then, the surface of the rubber mat, which had been flattened earlier, recessed to form a concave surface.

Yang Ming rolled the marbles into it again.

"As you can see. ”

The marbles move irregularly on the wrinkled surface, but are still attracted to the most recessed spots.

"That's why gravity-like phenomena can be created here even if there is no mass that gravity creates. ”

"But we didn't think gravity was anything strange when we got there?"

Hearing Sasakawa's words, Yang Ming smiled.

"Of course. Because there is earth with great mass. The distortion is so small that it can be said to be as weak as a tiny fold. Isn't that a difference that can be felt physically?"

Yang Ming said, placing the grenade on the wrinkled rubber pad again. The dent caused by Yang Ming's previous reach from below was eliminated by the weight of the grenade.

"Is it a distortion of space? Use this rubber cloth to illustrate how the space is and how it always feels like something. And what is the EVAI dimension?"

Kurata's words were scoffed at by Yangming.

"Hey, this is probably too reluctant for you stupid people, wahahahaha

After packing up the rubber mats and returning to their seats, Relai and Nanami Kuribayashi continued to ask questions to Yomei and Urushihata.

"The problem is the theory of extra dimensions. It is difficult to recognize the existence of additional dimensions in the first place. In any case, we will be bound by the three axes of horizontal, vertical, front and back, and the axis of time from the past to the future. Not any of them, but another kind of 'direction' that I can't even imagine. ”

"What could be in the 'direction' other than the flow of time from the past to the future?"

Hearing Nana's question, Yang Ming showed a bitter expression.

"I don't know, just speculating on it will do its best. Of course, I have some ideas. If we take into account the common elements of the nature of the direction axis. But this is speculation that cannot be proven. ”

"What is the common character?"

Nanami asked.

"Vertically, horizontally, before and after, and the flow of time. These can be mathematically set to extend infinitely from any point P to both positive and negative directions. As a result, the three-dimensional space-time thus formed contains two-dimensional, one-dimensional and other low-dimensional spaces, advancing along the axis of time flow. Then the elements of its high-dimensional space should also have the same properties. ”

"Yes, that's right. Lelai nodded yes. And then he began to say,

"I can explain that. ”

"Y-What did you say?"

"Originally, magic was the way to interfere with the outer side of three-dimensional space. ”

"Wait, wait, little girl. You mean you understand this?"

Yang Ming and the others leaned forward together.

Leilai nodded and said that this was something the Magus had to know.

"There is Ettel on the outside of three-dimensional space. ”

"Etter?"

"That's what we call it. ”

Leilai's instructions are very simple.

"Got it. Go on. ”

"Good. ”

Leilai preached. On the outer side of this world there are Ettel, Setter, Keitel, Fittel...... and other various direction axes.

"Just said it was on the outside, but that's wrong. Strictly speaking, it coexists with three-dimensional space. But we don't have an organ that can sense it, so it becomes the external manifestation. ”

“…… You say coincide?"

"That's right. Therefore, in this three-dimensional space, which is governed by the law that objects fall when they are thrown out, objects can also be blown away and float in the air. ”

Leilai ordered the rope that was lying on her stomach in the Chinook machine to float in the air and show them.

"This phenomenon arises by cutting off the 'present reason' of the three-dimensional space and interfering with the side of Setle that is dominated by the void. In the case of a ball that was previously rolled on a rubber mat, the phenomenon is similar to the behavior of grabbing the ball from the back of the mat. So it doesn't matter if gravity is there or not, it can make the object float. ”

"But how can you interfere with Settle?"

"So I said it. Three-dimensional space coincides with Setle. ”

"So even if it coincides, how can you interfere with the other side of the coincidence?"

"Setle and here overlap each other. ”

Even after listening to Leilai's explanation, "I don't understand the key part" Yang Ming tilted his head and thought.

"Three-dimensional space is divided into Ettel, Setel, Keitel, Fittel...... contains. It's not something else. So Setel is here, and Fittel is here. ”

"Ku, more than half of them don't understand—"
