"Lolita, you said this kind of thing has happened before?"

Juan, who helped Lolita finish the experiment, found a random box and sat down, waiting for the self-healing to be completed.

"Yes, I didn't follow Dr. O for long at that time, and it was the same way, and all of a sudden, the human network was disconnected.

"At that time, it caused a great panic among the human army, and the rebels took the opportunity to launch an attack, using forbidden spells to level the human base camp.

"If it hadn't been for the return to normalcy later, the human army would probably have been wiped out by the rebels."

"Later it got back to normal?"

"yes, otherwise how could you come?"

"Also, has Dr. O studied this phenomenon?"

"Yes, he spent a lot of time studying this phenomenon and came up with a hypothesis."

"Just hypothetical?"

"There's no way to verify it, so it can only be called a hypothesis, but it's all the same for me, I don't understand it anyway."

"You still don't understand? You're a scientist. ”

"I specialize in the art industry, and I don't know everything."

"You're so humble, then, do you remember this hypothesis?"

"Of course, I have a good memory, I'll recite it to you, but don't ask me to explain if you don't understand."

Lolita said, bringing over a trash can full of waste paper.

"According to Dr. O, the world is a garbage can......"

"I've heard this, and there's a song that says: 'The world is a garbage can, we're all garbage'......"

"Hey, don't just mess around, okay?"

"Okay, I won't sing, you continue."

Lolita pointed to the paper crammed in the trash can and said:

"There are a lot of parallel universes in this trash can world, and they are not intrinsically connected to each other, just like these papers, but they are crowded together, and there are individual places that touch."

Lolita pulled out a piece of polished A4 paper, a rolled tube, and a clump of paper from the trash.

"The space of these parallel universes is different, some are completely flattened, some are rolled, and some are clumped."

Lolita draws a dot on each of the three sheets of paper with a pen.

"The cosmic space is huge, and there is a galaxy in it, like this point, even much smaller than it.

"Therefore, for the intelligent beings living in this 'point', they cannot feel the true appearance of the universe."

Lolita picked up the polished A4 paper.

"The most likely thing for these intelligent beings is to judge that the entire universe is flat according to the characteristics of the space they are in, like this flat paper without wrinkles."

Lolita picked up the rolled paper and the clumps of paper instead, and showed Juan the dotted parts.

"Even if the universe they live in is in these two forms, they will think that they are in a flat cosmic space, because the position of this point is flat."

Juan nodded: "I can probably understand, just like the ancient people thought that the earth was flat, before they could observe the wider cosmic space, they would inevitably think that the flat space they were in was the shape of the entire universe." ”

"Yes, before I followed Dr. O, I thought that the earth on which I was standing was flat.

"I've heard that you humans have been circling your planet for a long time and proving that you are on a spherical planet, right?"

"Yes, that time is known as the Age of Discovery."

"When I want to go around the beautiful planet, even though I already know it's a ball."

"If you have a chance, let's go together."

"Well," Lolita nodded, retracting her thoughts, "So, the intelligent beings in the 'point' can't understand the movement pattern of jumping directly from one place to another. ”

Juan took the roll of paper from Lolita's hand and pointed to the stacked parts:

"We humans already know this, so we can make a space flight by jumping, which greatly reduces the time of the space voyage."

"But you don't understand this cosmic pattern yet."

Lolita shook the ball of paper.

"I didn't say it, it was Dr. O, who said that the flat and coiled universe might just be a very small exception to parallel universes.

He said that the most likely thing about the universe should be that it contains various shapes, that is, paper that resembles such clumps of paper.

"He called the universe in this state a 'multidimensional universe.'"

"Multidimensional? It's a lot in science fiction, but reality is only one-dimensional, two-dimensional, and three-dimensional.

Of course, there are also people who propose that time can be counted as one-dimensional, so the space we are in is a four-dimensional space.

However, many people disagree, thinking that time cannot be turned back and should not be counted in the spatial dimension.

"So, the current mainstream of human thinking is that the world is three-dimensional."

Lolita shook her head: "Dr. O believes that the cosmic space we are in is multidimensional, at least definitely not three-dimensional.

"The world is only three-dimensional because the galaxy we control, which is this 'point', is always in a flat part."

"I kind of understand what you mean, you mean that we, like the ancient people who thought that the earth was flat, mistakenly thought that the three-dimensional space we live in is the whole of the world."

"I didn't say it, I'm just reciting Dr. O's words, I don't really understand these things."

Lolita pointed to the line closest to the "point" and continued:

"The universe is in motion, and galaxies, which are the 'points,' move through the universe, and when it moves to this polyline, it touches another form of space."

Lolita uses her pen to draw concentric circles on the outside of the dots until she crosses the polyline and reaches the surface of the paper almost perpendicular to the original plane.

"Since galaxies are actually very large, this contact does not pass the entire galaxy at once, but a part of the galaxy's edge passes first.

"For example, our planet is at the edge of the star map."

Juan seemed to understand, and as he walked his fingers along the concentric circles drawn by Lolita, he said:

"Our planet revolves around a star, and a star revolves around the center of a galaxy.

"When the two are superimposed and reach a farthest point, our planet just bypasses the broken line and enters another space, just like now."

"Yes, that's how Dr. O explained it."

"Did he explain why he was disconnected?"

Lolita pointed to the broken line and said, "Dr. O said that this vertical space and horizontal space are actually the same three-dimensional space, but the twist is too drastic, like a broken optical fiber.

"So much so that along the 'optical fiber' -- that is, the three-dimensional space, the light that travels, there is no way to get from here to there.

The same is true of other electromagnetic waves.

He said that only in this way can it be explained that in the new space, the physical and chemical properties of the beautiful planet have not changed, but the connection with the original world has been severed.

Juan's fingers, sliding from the vertical surface of the paper, cut the horizontal flat surface at the folded line, and fell into the air.

He was a little puzzled and said, "Light travels in a straight line, so can't you get by?" ”

"No, that's not how I understand it, Dr. O said that light can turn, as long as the gravitational force is strong enough, but the turn is too drastic, and the light can't turn over, so he used the metaphor of a broken optical fiber."

Juan was even more puzzled: "If you can't even pass the light, how can the planet go over and come back?" ”
