Since ancient Homo sapiens had an indissoluble bond with grass, this magical species of human beings has an indissoluble bond with numbers. On the one hand, the advanced civilization of mankind can be said to be inseparable from the use and calculation of numbers. At first, people only used numbers to record time and things they encountered, but they soon found that the "numbers" made of grass were too monotonous, and everything recorded became the same until the emergence of Arabic numerals in the 3rd century.

Numbers symbolize the law as if they had just been created. They evolved from the original "1". The number "2" is 1+ 1, the number "3" is 2+ 1 and so on. At the same time, they symbolize everything.

After discovering many mathematical laws, people use different dimensions to describe different spaces, such as a point on a piece of paper, which is one-dimensional only including itself, and a line composed of countless points is two-dimensional, which has the concept of "length" on the basis of all the attributes of one-dimensional space, while "three-dimensional" is the dimension we are in now, which contains all the attributes of all two-dimensional worlds and has the concepts of width and height.

It can be inferred that there is a higher dimension above the three dimensions-four dimensions. The question of whether the four dimensions really exist was confirmed by a German mathematician "Riemann". So what mysterious changes will happen when human beings reach that unimaginable four-dimensional space? Next, let's explore together.

What is a four-dimensional space?

Speaking of four-dimensional space, in order to make it easier for everyone to understand, let's start with the most basic concept of one-dimensional space. We draw a straight line on a piece of paper to mark a point as the origin. The "point" representing one dimension in the two-dimensional space of "straight line" can be described by its distance from the origin, and all the numbers on this line can be described by a number. After understanding this, we draw a straight line perpendicular to the origin of this line and turn it into what we know.

After two points on two straight lines connect these two lines, a plane is formed, which is also two-dimensional. We can move them at will, they can only be two-dimensional. Then when a drop of water passes through them in this two-dimensional space, it becomes different together. Because there is no height in the two-dimensional space, the water droplets passing through the two-dimensional biological perspective only leave fleeting shadows in the two-dimensional space, just like dividing the water droplets in the two-dimensional space into countless cross-sections.

Similarly, when studying prime numbers, Professor Riemann found that there were countless insignificant zeros between 1 and 2, so he wrote "Assumptions Based on Geometry" and put forward the famous "Riemann Space" with the help of gravity, electromagnetism and calculus. By collecting and calculating the infinite details left by four-dimensional objects when they pass through the three-dimensional world, he calculates and infers the whole picture of four-dimensional objects, just as two-dimensional creatures infer the information of countless cross sections left by calculating "water drops"

Professor Riemann also confirmed to us that four-dimensional space is real, and it is extremely difficult to understand it thoroughly. But generally speaking, three-dimensional space is a "point" and a tiny detail in the "plane" of four-dimensional space. Four-dimensional space is the infinite integration of all three-dimensional spaces, and one attribute used to bind three-dimensional creatures is "time"!

Everything grows again and again, but it cannot escape time. I just don't know the time difference between the mushroom in the future and the Toona sinensis in 8000. If we describe our three-dimensional space as a video being played, then in the higher four-dimensional space, they can wave the progress bar at will, stop at a position where they want to pause, observe and immerse themselves in it, just as we have experienced it ourselves, and they can taste any details at will. For four-dimensional creatures, information will be fully unfolded, and time will.

In this regard, we can get a glimpse of some things in the four-dimensional space, and even some things have been explained. Just as a clever two-dimensional creature wants to break through the comfortable "height", human beings, as the smartest creature in our three-dimensional space, have always wanted to break through the shackles of life and time.

Megatron Yu Heng's first emperor couldn't get rid of this instinctive desire. In his later years, he searched everywhere for elixir. People with numb and full desires can't resist the temptation to get rid of the bondage of time. After entering the four-dimensional space and understanding it, it is as easy as drawing two lines on paper to create a two-dimensional space, and problems follow. What will the offspring become after entering the four-dimensional space?

Enter the four-dimensional "four-dimensional worm"

People always say that life is a stage play that cannot be replayed, and everyone is his own protagonist. In the four-dimensional space theory put forward by Riemann, we can find that human beings are also four-dimensional creatures, but they are not "absolute" four-dimensional creatures. We can only follow the flow of time without responding, and our senses can only passively accept it without changing it. Although we have the ability to create and change any three-dimensional object with length, width and height, we have no "organ" that can feel and change time.

We don't have some sensory organs that four-dimensional creatures should have, because the university has dabbled in Riemann extensively and has made great achievements in philosophy and theology. He came up with an unexpected conclusion that people can make up for this "defect" in other ways, that is, using "tools". Similarly, people found that two-dimensional objects can be transformed into three-dimensional objects by folding.

Just like the left view and top view we learned in primary school, a cube can be made up of six planes with the same size, so we humans can feel and even enter the four-dimensional space through similar "folding" methods.

And what will happen when people enter the four-dimensional space? We also need to compare by inference. Two dimensions create their nonexistent "heights" by folding six identical planes, so humans may become a "four-dimensional bug" with wireless time details after folding their "time" units into four dimensions!

From the perspective of time, everyone's infinite details about time are unfolding. They climb from their beds to schools, companies and shopping malls all the time. From the beginning of a time period to the end of a time period, we can observe and experience any day, hour and minute of these time details ...

Time does not pass, it is we who pass.

Based on exploration or knowledge, dreams or desires, people have great expectations for higher-dimensional space, but our tens of thousands of years of human evolution has also taught people the way to survive in a limited life, which has become a belief engraved in our bones and blood.

Therefore, even if bound by time, disease and death, it is better to seize the time to create your own value. After all, we are not four-dimensional creatures, and we only have one life. Who doesn't want to live a more meaningful life, right?
