This is the look of the cat looking up at the starry sky and crying sadly, which made Chen Nuo really shocked.

He could read the deep sadness and helplessness in the grey cat's eyes.

Originally, in Chen Nuo's cognition of this cat, he always felt that this cat was as timid as a mouse...

Um?A cat is as timid as a mouse and always feels that something is wrong...

Well, it was always thought that it was withdrawing from the competition, "abstaining" according to its own words, because it was cowardly.

And tonight, after the grey cat's words were finished, Chen Nuo suddenly understood...

Cowardice is not true or false, but there may be some "desperation" and "depression without hope" in addition to that.

"...So, do you think it won't work?" Chen Nuo lowered his voice.

"I don't know." The gray cat shook his head: "I hope to succeed, but..."

After this "but", the gray cat has closed his mouth and stopped talking.

"Okay, let's ask another question... What if it works? I mean if."

The gray cat still answered calmly: "I don't know."

Then it added: "We also don't know what four-dimensional life looks like and how it exists. So, how do I know? If it succeeds... that kind of thing is impossible to imagine."

That's right, low-dimensional life cannot understand and imagine the existence of high-dimensional life.

"Then say something, what you already know, or guess." Chen Nuo shook his head and said: "You have been busy for so long, long years, endless disputes, it is impossible that there is no progress until now, right?
Just as you said, your spiritual beings have already stood at the peak of life in three-dimensional space.

Then you should at least know something more than we do. "

The gray cat raised its paws, facing the direction of the sky, as if beckoning, and said, "I asked you just now, what is life."

"I answered it too, but you said it was inaccurate."

"Of course it's not accurate, three-dimensional life can only define three-dimensional life. But... it's not impossible to guess at all, there are always some imaginative ideas.

For example, haven't you humans been making a lot of theoretical guesses about the four-dimensional space? "

This Chen Nuo still knows a little about the guesses and assumptions about the four-dimensional space.

In fact, thanks to countless sci-fi works 20 years later, especially during the eight years of self-imprisonment at sea, Chen Yanluo, who was extremely bored, also read a lot of messy things to pass the time.

To put it simply and rudely, human guessing about the four-dimensional space is to add a dimension to the existing three-dimensional world.

A one-dimensional world is a line.

The two-dimensional world is a plane, that is, the length and the width, and the line forms a plane - the length and the width, which are the two axes of the two-dimensional world.

The three-dimensional world is: length, width, height.The line becomes a three-dimensional world with volume, so the three axes of the three-dimensional world are length, width, and height.

The so-called four-dimensional world is to find the fourth axis on the basis of the three-dimensional world.

As for what the fourth axis is, the mainstream speculative and hypothetical theories think it is: time.

time!

Chen Nuo's heart moved, and he tentatively said: "The fourth axis of the four-dimensional space is... time?"

"Maybe, maybe not." The gray cat shook his head.

"What do you mean?"

Chen Nuo frowned and said he couldn't understand.

Chen Nuo is not completely ignorant of the imagination of four-dimensional space, after all, a large number of science fiction works have similar discussions.

Time is the fourth axis of four-dimensional space.

To put it simply and rudely: taking time as the axis, superimposing countless three-dimensional spaces is the so-called four-dimensional space.

but……

Next, the gray cat said something with a smile.

"The so-called time, using your human definition of the material universe, is the manifestation of all material motion, change, and continuous sequence. That is to say, it is an abstract concept, but it can be observed and perceived.

But this 'observation' and 'perception' are also flawed.

That is to say, this 'perception' and 'observation' are also based on the material world, that is, under the theoretical framework of the 'three-dimensional world'.

The problem is... just as I asked you about the definition of life just now, what you and I have said is the definition of life in the three-dimensional world.

So, is time really the fourth axis?
The definition of time is: the continuity and regularity of the movement and change of matter...  

We live in a three-dimensional world, so our matter is in motion and change.So we define this movement and change with the concept of 'time'.

But the question is, is there really a change in the motion of matter in the four-dimensional space?
In other words, does the movement and change of matter really exist forever?
You humans have gradually discovered a lot. For example, the measurement of time is not absolute, but changes.

Another example, 'time' is based on perception and observation.

Even if one does not perceive or observe, the definition of time almost becomes a pure abstraction, which can be said to be 'non-existent'.

Therefore, taking time as the fourth axis of the four-dimensional space, we have always identified this direction before.

But...as you go further and discover more and more, that may not be quite the case. "

Seeing Chen Nuo frowning, Gray Cat suddenly changed his approach: "Let's talk about a very interesting statement made by one of your human philosophers, very idealistic, but very interesting."

"what?"

"You are a life, right?"

"of course."

"Okay, so let's say you're dead.

Then, there are two phenomena.

You are the one who destroyed the world.

For you, the world is actually destroyed.

understand?

The so-called world, if you look at it from your point of view, the country, family, society... your friends, relatives, your feelings, emotions...

The mountain is high, the sea is wide, the cake is sweet, the orange is sour, the wine is spicy, the tea is bitter...

These are the 'worlds' defined from your perspective.

From an individual's point of view, the so-called world, or the so-called "three-dimensional world", is an existence that you perceive and observe.

understand?

For you, a normal person, your world is bright.

But for a blind man born blind, his world is dark.

No matter how much you describe and explain to him, you can't make him understand what 'bright' is, and you can't make him understand what 'bright' is.

Therefore, the so-called 'world', in fact, is based on the perception of individual life, and what you perceive constitutes the 'world' defined by you.

And once you're dead...

Chen Nuo, for example, at this moment, you suddenly died.

So for you, it's not that you're dead.

But your 'world' is destroyed.Your children, your women, your friends, your family, your career, your country, everything you know in this world... in the moment you die, perish, perish. "

"...But, it still exists, this is objective." Chen Nuo frowned: "Even if I die, the world still exists."

"But for you as an 'individual', you are destroyed, because you are dead, you can no longer perceive or observe, so your world is destroyed." The gray cat said this and smiled: "From this definition, ...Actually, the world perceived by each living individual is different.

Someone who was born blind, someone who was born deaf, or someone who was born color blind...

Broadly speaking, you and these people exist in the same world.

But specifically...from a personal point of view for each of you, the world is different again. "

"So... time is not the fourth axis of the four-dimensional space?" Chen Nuo asked.

"No... As far as our guesses are concerned, time is likely to be the fourth axis." The gray cat replied again.

Chen Nuo widened his eyes.

"But this time, not that time.

The time we define is the three-dimensional life of the three-dimensional world. According to the scope of our ability to observe and perceive, we have observed, perceived and summarized the changes and movements of the three-dimensional matter in the three-dimensional world. Conclusions and definitions.

That is to say, what we now call 'time' is, to be precise, 'time in three-dimensional space'. "

Chen Nuo generally understood what the gray cat meant.

The "life" defined by us human beings, to be precise, is not the definition of life, but the definition of "three-dimensional life".

Because we ourselves are three-dimensional life, we can only perceive and observe three-dimensional life, so we can only define three-dimensional life.

Similarly, the "time" defined by us human beings is not the definition of time, but only the definition of "three-dimensional space time"!Because we are three-dimensional beings, we can only perceive and observe time in three-dimensional space!We can only define time in three-dimensional space.

Maybe... the 'time' of the four-dimensional space, and our definition of 'time', are different! !

Chen Nuo thought for a while.

Human beings, three-dimensional life, define time as: the regularity and continuity of the changes and movements of [matter].

But...if the definition of "matter" in four-dimensional space is different from that in three-dimensional space, then the so-called time will naturally have a different definition.

This Chen Nuo is generally understandable.

One dimension is a line.

[-]D is a plane.

So let's not talk about one-dimensional.

The matter of the two-dimensional world (plane world) is definitely different from the matter of the three-dimensional world.

Then, most of the matter in the three-dimensional world is also different from the matter in the four-dimensional space.

Since the matter is different, the concept of 'time' is summed up based on the observation of matter in the three-dimensional world.

Naturally, it is very likely that it cannot be applied to the four-dimensional space.

So, time in four-dimensional space... What is it used to define?

The continuation and regularity of the movement and change of matter...

Chen Nuo thought about something in his heart.

If matter is different, how else can time be defined?
What is used to define?What else, is universally applicable to three-dimensional and four-dimensional space, but can be compatible with: motion, change...continuous, regular...these conditions?
Then, Chen Nuo suddenly took a deep breath and looked at the gray cat.

The gray cat smiled: "Guess it?"

The gray cat nodded: "Actually, this... is just our guess, and it may not be accurate. After all, we have not succeeded, nor have we reached the finish line, and no one knows what the door will look like after that."

Chen Nuo looked solemn: "So... the fourth axis of the four-dimensional space is indeed time.

But this 'time' is different from the 'time' we define.

The concept of time that we define with 'matter' as the object of observation does not apply to four-dimensional space.

According to your guess...

The definition of 'time' that conforms to the standard of four-dimensional space does not use 'matter' as a scale.

But...

life! "

From the individual perspective of each life, the observed world is different.

Countless beings, theoretically speaking, is equivalent to having countless worlds and countless three-dimensional spaces.

These countless three-dimensional spaces are superimposed on the axis of life time, which is the so-called four-dimensional space.

That's what the grey cat wanted to say.

The life time here is not how many years and days the so-called life can live...

but something else.

"In simple terms, it is the birth, the death of an individual life. That is, the 'movement' and 'change' in the definition of time.

Every life has its birth and its death. This is continuity and regularity.

This is the 'time' measured by life.

'Time' in four-dimensional space. "

The gray cat shook his head: "Getting this guess and assumption is the guess of our spiritual beings, or that sentence, we don't know if it's right or wrong...

Probably right.

But more likely, it is wrong.If it is wrong, then the end result is that we run, search, and evolve with all our strength in this direction.

At the end of the run, I found that what awaits us is not the finish line of successful evolution, nor the door that pushes open to jump out of the third dimension and reach the fourth dimension.

And it may be a dead end, an iron wall.

But... no matter what, with what we currently have, all the power we have, the position we stand, what we can see, what we can summarize, and what we can guess, that's all. "

Yes, hypothetical.

However, the height of the ecological niche occupied by the parent civilization and seeds is obviously higher than that of humans.

In their own words, standing at the pinnacle of three-dimensional life.

So maybe, maybe, their guesses are closer to the real answer than what humans are currently assuming?

"Then here comes the problem.

If the fourth axis of four-dimensional space is really time.

If the time definition of the four-dimensional space is based on 'life' as the scale, not matter.

So……

Back to my original question.

Chen Nuo...

life, what is it?
Or, let me put it another way.

Where does life come from? "

Chen Nuo was speechless.

Where does life come from?
this problem……

Suddenly he remembered something.

Humans are born of human beings, and demons are born of monsters.

What's your mother's last name?

[Very important words:

First, I am a liberal arts student, so these things are all messy things I usually read and dabble in, and then I imagined them myself.To put it simply, it is more civil than civil science!Real science students, brothers and sisters studying physics, especially theoretical physics, don't laugh at me, it's just a novelist's imagination.

Second, I know that the contents of these two chapters are about concepts.However, in a novel of more than 200 million words, there must always be some chapters used to explain the world view and the basic setting of the story. This is unavoidable.I will try to simplify these things as much as possible, but at the same time, I will try my best to explain it clearly.However, such chapters are necessary.

Third, this book is not sci-fi, and I, a civil subject like me, can’t write sci-fi either. It just borrows some concepts as a part of perfecting the setting logic.

that's all.

Tomorrow is the Chinese New Year, here I wish everyone a prosperous and prosperous year of the tiger, and the tiger will prosper! 】
