If you want to escape, you must first figure out how many dimensions this damn place is, how big is this space, and ...... Will he be able to move in a higher dimension?

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

Zhang Yuan worked hard to stretch his fingers to the fourth dimension.

A miracle happened, and he actually succeeded!

With a slight hint of obstacle, his fingers pierced through the closed spacesuit, burrowed out of the fourth dimension, and entered a void. It's a strange feeling, as if the whole picture is directly torn, and it is impossible to do it without a high-dimensional perspective.

The fingers quickly developed a cold, swollen touch that did not completely disintegrate.

"Good." Zhang Yuan was overjoyed and retracted his fingers again.

Second, if this space is very large, even the size of the solar system, relying on the spacesuit's ejection device, the probability of finding an exit is still zero.

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

Soon, because of the huge amount of information received, my head began to heat up.

This place seems to be full of mirrors with countless images of itself!

He felt like he was surrounded by mirrors!

When he looked straight ahead, he saw the soles of his feet, not just once, but seven, eight, nine times...... It seems like there are countless times!

This 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 myself and this spacesuit!"

A lot of sweat oozed from his head, and Zhang Yuan tried to make himself calmer.

He deeply experienced the pain of a high-dimensional life.

"Maybe it's not painful for high-dimensional beings, it's just that the perception of low-dimensional people like me can't adapt to it."

Zhang Yuan didn't dare to move indiscriminately, he had already been twisted into a ball, maybe he would move at will, and his fingers would penetrate into his heart from another dimension.

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

The flashlight in the spacesuit was still on, so he moved back and forth, adjusting the angle little by little, and tried again and again.

Let's start with 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 such a simple situation......

It is impossible for him to use the trajectory of light to estimate the curvature in space. There is no air in the space, and it is impossible to produce the so-called Tyndall benefit, so he cannot see the complete path of light.

Even if he sees the path of light, because of the limitations of his own perspective, he will most likely think that this light is a real straight line.

Unless he jumped into a higher dimension to take a global view, he would find that the trajectory of the light was distorted.

Soon, Zhang Yuan thought of some other methods...... He could deduce what was going on in this damn space by looking at himself and the strange distortions of his spacesuit. In addition, the scene he saw, some bright and some dim, should also have something to do with the trajectory of the photon's movement.

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

"The beating heart is the heart?"

"That...... Is it the stomach? ”

"That...... What is it? It won't be the apple I ate today, right? ”

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

The various organs of the human body itself are too complicated, and all kinds of irregular shapes dazzle Zhang Yuan, and even produce a desire to vomit.

He quickly turned his attention to his spacesuit.

He was much more familiar with the spacesuit than his own body, and soon discovered some parts with regular structures.

cubes, as well as all kinds of gears!

Using mathematics, it is possible to judge the specific dimensions of this space.

In a three-dimensional space, there are only 5 types of polyhedra, tetrahedron, hexahedron, octahedron, dodecahedron and icosahedron, and there can be no more.

In the dimension of four-dimensional space, six kinds of regular polyhedra can be constructed, one of which is the "hypercube", which is a regular polymorph in four-dimensional space, surrounded by 8 cavity cubes, as if a cube is surrounded by 6 square faces.

In the five-dimensional world, only 3 types of regular polyhedra can be assembled......

In each different dimension, the solid geometry will take on different properties.

After an hour-long observational calculation, he came to a final conclusion.

It's not a four-dimensional space.

It turned out to be ...... Nine-dimensional space?!

Zhang Yuan didn't know if he had miscalculated, and when he came to this conclusion, he felt that he was about to suffocate.

From one point of view, all matter is still three-dimensional, and the other six dimensions are so small that they can only be observed very narrowly. It was these additional six dimensions that had twisted him into what he was today.

To take a not-so-figurative example, he is like a two-dimensional life embedded in paper. The paper appears to be just a flat surface, but it is actually three-dimensional, but very small.

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

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

Why is this so? Could it be that this world itself is nine dimensions? Add time to that, that's 10 dimensions? ”

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

Moved his body again, as if the whole ball bounced, and thought to himself, "This place seems to have gravity...... But I was in the void again, and I didn't fall in the direction of gravity...... What is holding me back? ”

"It's weird to the extreme."

At this moment, the exuberant curiosity has masked the original fear.

Anyway, in the end, whether he is dead or alive, he has to continue to explore......

Even if it was obviously not enough to know that it was the nine-dimensional space, there was still no way to help Zhang Yuan escape from this place, he still had to know what was going on in this strange space, and where the damn warp point was!

This point is too difficult, even the path of the light itself has been distorted, and it is impossible for Zhang Yuan to get any hints at all.

"Wait a minute, why am I being twisted into a ball? Does it have something to do with the nature of the space itself? ”

Zhang Yuan frowned, thinking crankily.

Gradually, a famous space came to mind.

Calabi-Yau space?!

The space that exists in this theory, which is smaller than a proton, can be linked to string theory in an inexplicable way.

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

Therefore, the photon that Zhang Yuan saw had been tossing back and forth several times in the extra six dimensions, like riding multiple roller coasters, and finally, it ended the whole trip and stopped on his back, which will show the current situation.
