Mound Space

If you want to escape, you must first figure out how many dimensions this damn place is, how big this space is, and whether he can move in higher dimensions.

If it can only move in three-dimensional space, then the probability of finding the exit is almost zero.

Zhang Yuan tried his best to extend his fingers to the fourth dimension.

A miracle happened, he succeeded.

With a slight obstacle, his fingers penetrated the closed spacesuit, got out from the fourth dimension, and entered a void. This feeling is very strange, as if the whole picture is torn directly, and it is impossible to do it without a high-dimensional perspective.

The fingers quickly felt a cold, swelling sensation without completely disintegrating.

"Very good." Zhang Yuan was overjoyed, and retracted his fingers again.

The second point, if this space is very large, even as large as the solar system, the probability of finding the exit is still zero by relying on the small injection device of the spacesuit.

Zhang Yuan rested for a few minutes, gathered his spirit, and carefully observed the distance.

Soon, due to the huge amount of information received, my mind started to get hot.

This place seems to be full of mirrors, with countless images of himself.

He seemed to be surrounded by mirrors

. When he cast his eyes straight ahead, he saw the soles of his feet, not just once, but seven or eight times. , Nine times, there seemed to be countless times

such a huge amount of information made Zhang Yuan's head almost collapse again.

"There is no space in the traditional sense at all. The whole world is just me and this spacesuit." There

was a lot of sweat on his forehead, and Zhang Yuan tried to calm himself down.

He deeply experienced the pain of high-dimensional life.

"Perhaps it is not painful for high-dimensional life, but the perception of low-dimensional people like me can't adapt."

Zhang Yuan didn't dare to move indiscriminately. He has been twisted into a ball. Use your fingers to penetrate into your heart from another dimension.

In this kind of place, in case of such an accident, it is almost impossible to save the gods.

The flashlight in the space suit was still on, so he moved back and forth, adjusting the angle bit by bit, testing again and again.

Consider first the simplest four-dimensional space.

If the three-dimensional space is distorted to form a four-dimensional Klein bottle, there is no doubt that a beam of light emitted from the front can indeed hit one's back.

But soon, Zhang Yuan discovered that it was not so simple that

he could not use the trajectory of light to estimate the curvature in space. There is no air in the space, so it is impossible to produce the so-called Tyndall effect, so he cannot see the complete light path.

Even if he saw the light path, because of the limitation of his own perspective, he would probably think that the light was a real straight line.

Unless he jumps to a higher dimension for global observation, he will find that the trajectory of light is distorted.

Soon, Zhang Yuan thought of another way. He could speculate what was going on in this damned space by observing the strange distortions of himself and the spacesuit. In addition, some of the scenes he saw were bright and some were dim, which should also be related to the trajectory of photon movement.

Imagining a high-dimensional space is definitely a brain-burning thing, because it is far beyond Zhang Yuan's daily experience. This kind of omniscient dizziness is transmitted every few seconds.

"The beating thing is the heart"

"That is the stomach"

"What is that? Could it be the apple I ate today?"

I don't know why, but all the original structures can still be used, that is to say, the high-dimensional world is actually compatible with the low-dimensional world.

The various organs of the human body are too complicated, and Zhang Yuan is dazzled by the various irregular shapes, and even has a desire to vomit.

He quickly turned his attention to his spacesuit.

His familiarity with the spacesuit was much higher than his own body, and he quickly discovered some parts with regular structures.

The cube and various gears

use mathematics to determine the specific dimension of this space.

In a three-dimensional space, there are only 5 regular polyhedra, regular tetrahedron, regular hexahedron, regular octahedron, regular dodecahedron and regular icosahedron, and there cannot be more.

In the dimension of four-dimensional space, 6 kinds of regular polyhedrons can be constructed, one of which is "hypercube", which is a regular polyhedron in four-dimensional space, surrounded by 8 cell cubes, like a A cube is generally surrounded by 6 square faces.

In the five-dimensional world, only three kinds of regular polyhedra can be assembled.

In each different dimension, the three-dimensional geometry will present different properties.

After an hour of observation and calculation, he came to a final conclusion.

Not four-dimensional space.

It turned out to be the nine-dimensional space.

Zhang Yuan didn't know if he had made a mistake in his calculations. When he came to this conclusion, he felt like he was about to suffocate.

From a certain angle, all matter is still three-dimensional, and the other six dimensions are very small, and can only be observed very reluctantly. It was these extra six dimensions that twisted him into what he is today.

To give an inconspicuous example, he is like a two-dimensional life inlaid on paper. Paper looks like a flat surface, but it is actually three-dimensional, only with a very small thickness.

Extending a piece of paper to nine dimensions, and extending the two-dimensional to three-dimensional, is his current situation. The

nine-dimensional perspective is so novel, it's no wonder that all kinds of information are as huge as a flood.

"Why is this so? Could it be that the world itself has nine dimensions? Adding time makes it ten-dimensional." The

ten-dimensional space reminded Zhang Yuan of some inferences in physics.

I moved my body again, just like a whole ball bouncing, thinking in my heart, "This place seems to have gravity, but I am in a void again, and there is no force to push me if I don't fall in the direction of gravity. I'm stuck."

"It's so weird to the extreme."

At this moment, the exuberant curiosity has covered up the original fear.

Anyway, in the end, it is life or death, and he has to continue exploring.

Even if he knows that the nine-dimensional space is obviously not enough, there is still no way to help Zhang Yuan escape from this place. He still has to know how this strange space turns out.

It is really difficult to find out where the damned warping point is . Even the path of the light itself has been distorted, and it is impossible for Zhang Yuan to get any hints.

"Wait a minute, why am I distorted into a ball? Could it be related to the properties of the space itself?"

Zhang Yuan frowned, thinking wildly.

Gradually, a famous space came to mind.

Calabichu space,

a space smaller than a proton, exists in the theory of Calabichu space, which can be related to string theory in an inexplicable way.

In this space, there is no straight line, every place is constantly bending, and you may be able to touch your back and the soles of your feet when you reach out.

Therefore, the photon that Zhang Yuan saw has been tossing back and forth in the extra six dimensions for several times, just like riding many roller coasters. In the end, it ended the whole journey and stopped on his back. present the present situation.
