Hyperspace, this is a world that is completely different from ordinary space.

Here, everything around them disappears, and the only thing that can be seen is a myriad of lights.

Surrounded by colorful lights, the scene is like being in the midst of countless auroras.

This is not the first time Yun Qi has seen this kind of scene.

After all, Infinity itself can also travel in hyperspace, although the technical principles are somewhat different, but fundamentally speaking, they all use hyperspace to distort the material world to achieve the purpose of exceeding the speed of light.

Today, however, the hyperspace leading to the Precursor ruins is a little different.

The usual hyperspace passage is a straight, tube-shaped passage surrounded by colorful auroras. According to the experts, these lights are not actually the light of the hyperspace channel itself, but the projection phenomenon that occurs when space is extremely compressed.

Of course, in order to explain this so-called phenomenon of dimensional projection, those experts have written a rather thick proof of civilization. However, when he saw that the directory of this electronic document alone exceeded one G, Yun Qi decisively skipped the previous explanation and read the conclusion directly.

With a total size of more than 15,000 G of supporting documents, who TM has a problem reading them from beginning to end!

Skipping all the proof processes, Yun Qi saw the conclusion that the essence of hyperspace is the ascent of dimensions. No matter how many dimensions there are in the universe, its essence is a continuous superposition of one-dimensional, two-dimensional, and three-dimensional.

One dimension is points and lines, two dimensions are surfaces, three dimensions are space, but what about four dimensions?

For most humans, the fourth dimension is time. But how to consider the dimension of time?

The three-dimensional world is very simple, it is three axes of xyz. As long as the position coordinates on the three axes of xyz are determined, the spatial position of any object is determined, but how to understand the fourth dimension?

There is nothing wrong with the fact that the fourth dimension is time, but the dimension of time is actually unrecognizable or defined in our human brains. We can imagine three-dimensional space, but we can't imagine the fourth dimension of time.

There is a saying that human beings live in a three-dimensional world, so it is impossible to describe the four-dimensional space. It's like an ant in a two-dimensional world, never able to understand the existence of humans.

There's an interesting experiment about ants. Ants rely on smells and antennae to perceive the world, and in their minds, the whole world is a huge plane, so for ants, there is no up or down at all. Whether it's flat ground or steep cliffs, it's actually the same as a flat surface for ants.

The reason for this is that the main sensory organ of ants depends on smell, not on the eyes.

Somebody once did an interesting experiment, and it went like this. Place an apple on the path that the ants must pass through, and when the ants smell the apple and want to come and feed, lift the apple into the air.

Since the apple is in mid-air, when the ants come to the bottom of the apple according to the taste, they will be puzzled to find that the apple is gone. But the smell of apples still kept coming down from mid-air, telling the ants that I was here, right above your heads.

It's a pity that for ants who don't have the concept of space, their consciousness is that the apple has disappeared out of thin air, and they will only look around the smell of the apple and look around and circle under the apple, but they will not find the apple there anyway.

This classic experiment teaches that creatures living in two-dimensional worlds cannot perceive three-dimensional worlds. But the existence of a three-dimensional world can have an impact on a two-dimensional world. Like that apple, it smells, it creates a shadow on the ground, and that's what the three-dimensional world does to the two-dimensional world. By analogy, human beings are creatures living in the three-dimensional world, so they cannot perceive the four-dimensional world, but they can feel the influence of the four-dimensional world on the three-dimensional world, such as the passage of time.

Although they cannot feel it directly, human beings rely on their own intelligence to calculate the existence of the four-dimensional world. According to the law of dimensional superposition, high-latitude spaces are composed of countless low-dimensional spaces. Just like a two-dimensional plane is made up of an infinite number of one-dimensional lines. Three-dimensional space is composed of countless two-dimensional planes, so four-dimensional time is composed of countless three-dimensional spaces.

And the five dimensions are countless combinations of four dimensions.

By analogy, if there is a higher-dimensional six-dimensional space, it is composed of an infinite number of five-dimensional spaces.

According to scientists, the entire universe is actually a huge cone, and the smallest point at the top of the cone is the highest dimension of the universe, the sixth dimension. The lowest end of the cone is made up of countless one-dimensional points and lines.

If we use the language of dimensions to describe the universe, the entire universe is a six-dimensional point composed of countless one-dimensional, two-dimensional, three-dimensional, four-dimensional, and five-dimensional.

And the hyperspace passage that can cross long distances in an instant is a four-dimensional space.

Each unit of distance that the spacecraft moves can actually be understood as the spacecraft itself moving through the three-dimensional space at another point in time. This can be understood as the universe an hour ago and the universe an hour later. These two universes actually exist at the same time for the four-dimensional space, but they have a sequence, and the only difference is that the spaceship was in position A an hour ago, and has already arrived in position B an hour later.

The movement of this position gives humans the feeling that time has passed.

When the spaceship keeps moving, if you want to go from one end of the universe to the other, in the fourth dimension, it is an infinite number of three-dimensional universes arranged together, and the spaceship just travels from the universe an hour ago to the universe an hour later, and so on and so forth, and finally reaches its destination.

In a sense, this is very imaginary with a labyrinth. Many of the maze entrances and exits are actually very close to each other, but when people enter the maze, it almost takes a certain amount of time to get out. Each labyrinth grid is like a three-dimensional universe, and every time a human walks through a labyrinth grid, it is equivalent to passing through a three-dimensional universe. The reason why people have to walk this way is because the walls in the maze lattice restrict people, so that people have to honestly follow the maze lattice one by one.

But if you flatten the whole maze into a chessboard, you will find that the entrance and exit are only one square apart, and you can reach the destination by crossing the grid.

Of course, the jump in hyperspace is not so simple, but the general principle is similar. These grids represent an infinite number of three-dimensional worlds, and if you go directly from the four-dimensional space, that is, the hyperspace, over the walls that limit these grids, you will go straight to your destination.

However, the real hyperspace jump does not jump directly from the starting point to the end, but directly crosses the countless squares in the middle and reaches the end. That's why the scene that Yun Qi had just seen appeared in the hyperspace passage, and countless Ambilights surrounded him. Those are actually the projections left in hyperspace by the points and lines that have been compressed into countless three-dimensional spaces.

Although after reading the conclusion, Yun Qi has a general understanding of what hyperspace is, but the hyperspace he entered this time is obviously different from what those experts said.

Because after flying for a period of time, the entire hyperspace passage suddenly rises and expands, and then becomes a huge three-dimensional space.

According to space theory, this is impossible.

Because the essence of four-dimensional space is a straight line composed of countless points formed in three-dimensional space.

Therefore, time can only flow forward, not backward, let alone move left and right, or up and down!

But now, an infinite three-dimensional space actually appeared in Yun Qi's sight.

The scale of the entire space exceeds the limit of Yunqi's perception. Or that is no longer a world that human organs can perceive.

That's the existence above the four dimensions, the fifth dimension. It is also the birthplace of parallel universes.

The fifth dimension is like a broad plane, and its essence is composed of countless four-dimensional lines.

Each four-dimensional line is a stream of time, and each stream of time is a parallel universe.

Parallel universes are already part of the multiverse in the strict sense of the word. It's just that the parallel universe is based on the countless mirror universes generated on the main universe. Each mirror universe is a possible branching change in the main universe.

But only one mirror universe will become the real main universe, and the rest will always be mirror universes that may or may not exist. These parallel universes are, to put it bluntly, a possibility of the main universe.

But the concept of parallel universes is by no means understandable to ordinary civilizations. A first-level scientific and technological civilization can understand and control the four-dimensional space, control the hyperspace, and complete an unprecedented river-level jump, all of which can be achieved from the perspective of science and technology! But it is absolutely impossible to grasp the mysteries of the five-dimensional space. Entering the five-dimensional space is equivalent to transcending the universe, like a carp jumping out of the water gate, and can freely choose the direction of the universe.

Such an existence is even more awesome than that of him, a true god!

And soon, Yun Qi discovered the existence that controlled this magical space, an extremely large man-made object.

It was a strange lotus-like object.

It's just that when Yun Qi discovered it, the entire Infinity appeared within the range of this lotus-shaped man-made object as if it were teleporting. And then it's like entering an infinite loop space, and you can't leave it again.
