Takashi Kato is not a person who likes to joke around, and he categorically would not say such a thing if he did not have a certain certainty.

"Can't get out? Is it because we can't dive without oxygen tanks? As soon as I heard Taka Kato say this, my heart sank, "Bang! He asked after waving his knife to chop a "hundred households of the same kind" that fell from the sky.

Even if it is very difficult to get out, it should be possible to get out, at least, Abe Harumi is a living example.

"If you can't get out, how did the one called Baihushi do it?" Yue Mingmo lightly danced the naginata, and no flying monster could get close to him.

"That's it, Dean Kato, your old man hasn't studied it well, so it seems a bit inconsistent with your scientific spirit to draw conclusions like this. What is the origin of these flying human skin dumplings? It's not fatal, but we're going to be in trouble if we continue to be entangled like this. The stallion whistled as he waved his knife.

"It doesn't matter, although these gliding human skin monsters are annoying, as long as you are familiar with their attacks, they are still easy to deal with, as long as you can rush out of this forest quickly, there is no threat to us. His Excellency Kato is protected by three long-mouthed little brothers, so you can rest assured to tell you why. Lao Zhou said.

"Well, since we came here, I've been thinking about a question, even if there are those amazing structures that can withstand the impact of the sea, how much pressure does such a huge space have to bear? Even if it wasn't Xu Fu who was buried here, judging from these ancient trees alone, this space had existed for at least a thousand years, and if that were the case, this space would have been crushed long ago. So I didn't figure out why, until Big Ears said that there might be a huge waterfall falling from the sky in front of me. Takashi Kato's solemn voice came from the communicator.

"We can often see waterfalls, does this have anything to do with not being able to get out?" The stallion asked.

"You don't know and you can't blame you for this, after all, no one has ever touched it. Have you ever heard that there is a bottle in the world that can never be filled with water? Takashi Kato asked.

"Yes, a bottle with a hole." The stallion replied earnestly.

The stallion's answer was of course wrong, and Taka Kato wasn't so boring as to tell bad jokes.

Although I am a liberal arts student, I still pay attention to these strange things from time to time, but I don't know enough about them, and when I hear Takashi Kato say this, a strange term pops out of my head.

"Is it a Klein bottle? But it's impossible to exist in three-dimensional space. Yue Mingmo asked one step ahead of me, but I didn't expect her to know.

"Satsuki-san, your understanding is very high, that's what I want to say." Takashi Kato praised, his tone a little happy.

"What does Lord Kato mean that we are all in one big bottle? Isn't that the same as the situation when Sun Wukong met the King of the Golden Horn and the King of the Silver Horn? It's so much fun. Manjiro said happily with some confusion.

"Well, I'll talk about it briefly." Taka Kato began popular science when we were constantly slashing and killing "the same kind of people in the hundred households".

Strictly speaking, the Klein bottle is a mathematical term that refers to a non-orientable topological space.

The structure can be expressed as follows: a bottle has a hole at the bottom, which now extends the neck of the bottle and twists into the inside of the bottle, and then connects with the hole at the bottom.

Unlike the cups we usually use to drink water, this object has no "edges" and its surface does not end.

However, unlike a sphere, a fly can fly directly from the inside of the bottle to the outside without having to cross the surface, because there is no distinction between inside and outside.

This is an idea put forward by the German mathematician Klein, and so far no concrete objects have been produced, and now there are only computer models.

As the model shows, the Klein Bottle is a strange bottle with a black hole at the bottom, and then the mouth of the bottle leads to the bottom of the bottle after being twisted indefinitely.

Whatever you put in it cannot be kept inside, even an ant will naturally walk from the inside to the outside, and there is no need to go through the surface of the cup at all, it is a non-orientable topological space.

If there is one sentence, it is this: the Klein bottle has no distinction between inside and outside, it is a thing that can only exist in the four-dimensional world.

In real life, in the three-dimensional space we live in, there is absolutely no Klein bottle.

Taka Kato was happy to see that his scientific discussion was no longer high-minded, and the others were also at a loss, but I now feel a little ridiculous.

It's not that Takashi Kato's speculation is ridiculous, but because, if he is telling the truth, if we are all in a Klein bottle, the exit is the import, and the curved part of the bottle does not intersect with itself, just like the past and the future in the four-dimensional space, any object becomes the past when it comes in, and the future when it goes out.

Wouldn't the only way we have to get out is to wait for those big jellyfish to migrate again? What's the difference between this and waiting to die? No way, there must be another way! Otherwise, I wouldn't have been able to see the living Abe Haruaki!

"How amazing is it? After Dean Kato's explanation, I understood, that is, we can come in and go out from anywhere? But can anyone explain to me why I can't just sneak out like Tuxingsun? The stallion asked, standing next to me and stomping the ground.

"You'd better pray not to go out suddenly, or you won't know what awaits you, right? So, I don't think it's a Klein bottle. I said with a slight frown.

As soon as the stallion heard me say this, he immediately came back to his senses, and his face changed, and even his steps were much lighter than that of slashing monsters.

"Ouyang is right, there are many places here that are contrary to the Klein bottle." Yue Mingmo said.

"Well, I think that those unproven theories can be doubted and disproved, because no one has experienced them, and their conjectures, no matter how impeccable they may seem, will inevitably be true in practice. Even the man who invented this theory did not see the existence of the Klein bottle with his own eyes until the day he died. If you don't see it with your own eyes, who knows what the truth is? I'm excited right now, are we about to reveal the secret of the Klein Bottle? Takashi Kato said.

Tatsuku was not interested in what we were discussing, and seeing that we were all concentrating on the discussion, he very consciously took on most of the responsibility for chopping the human skin dumplings.

"Don't get too excited, let's wait until we can live out of this forest, we're in big trouble." I took a deep breath, looked at the huge ancient tree in front of me, and said with a little horror.
