At present, the most popular theory about "self-consciousness", called "Boltzmann self-consciousness", is a hypothesis differentiated from "Boltzmann brain".

The low entropy world observed by human beings comes from the random fluctuation of the high entropy universe.

Large fluctuations can cause a state of low entropy. Although the probability of low entropy is very low, it will still occur on a broad scale of the universe.

Further deduction can be drawn: this fluctuation may produce a brain, that is, self-consciousness, and its probability is much greater than that of producing the low entropy world in which human beings live and evolving a large number of brains.

It can be calculated that the probability of fluctuating out of the human world is e ^ (- 10 ^ 100), while the probability of fluctuating out of the Boltzmann brain is e ^ (- 10 ^ 28), a difference of more than 70 orders of magnitude.

Further deduction of this hypothesis leads to the origin of human self-consciousness.

At the same time, self-consciousness can also be divided into "weak consciousness" and "strong consciousness". Cameras, computers and other machines that can record the operation data of the universe also have "self-consciousness", but these things belong to the category of "weak consciousness".

Those who can deduce the system of cosmic motion through logic belong to the category of "strong consciousness".

The observation behavior of "weak consciousness" and "strong consciousness" can affect the movement of the universe itself, which explains the strange phenomena such as double slit interference and the reversal of cause and effect in some micro fields.

Therefore, the mystery of self-consciousness may be hidden at the root of the universe

Well, Zhang Yuan just takes these conjectures as a pleasure.

"Conjecture in conjecture" can not be verified by experiments, let alone further development. Nature cannot reveal the root of self-consciousness, and eternal life is impossible.

Moreover, he found that there seemed to be more and more conjectures that human beings could not verify with experiments.

From the beginning of high-energy physics, to condensed matter, to the current life science, to biology, there may be more and more disciplines that cannot be further developed in the future

He instinctively felt a great crisis from the vast universe!

An invisible net divides the forbidden zone of transcendence and mediocrity.

As long as beyond the restricted area, what people feel is a blank and boundless unknown, and they can no longer continue to develop.

……

With the passage of time, the time of hibernation will come again.

With uneasiness, the kind of uneasiness about the future

This time, Zhang Yuan will hibernate for 329 years and shuttle directly to the 31st century.

"Mr. Zhang, after testing, your physiological indexes meet the conditions of hibernation. I wish you a pleasant time trip. "

His life partner Lin Xuanxuan went into hibernation a month early. Another nurse saw him off, which made him very embarrassed.

"You can record a paragraph and bring it to yourself in the future."

"Thank you." Zhang Yuan nodded, "... This awakening is not so wonderful. On the earth, there is a crisis in both the human environment and the development of science. I just hope that the next time I wake up, earth civilization can solve these crises. "

"OK, I recorded it... Is there anything else you want to say to this era?"

Zhang Yuan said, "no more."

"I wish you a long way and good luck..."

"I hope so."

……

The earth time is crawling slowly in the deep air, and time flies like a meteor.

One hundred years, two hundred years, three hundred years

It's time to get off again.

This time, there seems to be a little accident.

"What? I slept more... 150 years? " Zhang Yuan was lying on the hospital bed and was surprised to see the atomic clock on the wall.

"What happened? What about... The meeting on the history of new civilization? I missed it again? " He opened his mouth and asked in a hoarse voice.

"Hello, Mr. Zhang. It's 3234, the 33rd century. Nothing big happened to the spaceship. In the past few years, several groups of children were born in the spaceship, and your waking time was crowded out. "

"Accordingly, the meeting of new civilization historiography was postponed." Said the nurse.

Hearing that the meeting was postponed, Zhang Yuan instinctively felt uneasy. This kind of meeting does not mean that it will be postponed. Something extraordinary must have happened.

And he found that the female nurse had a trace of wrinkles on her face, as if she were older than a normal astronaut.

"This lady... What about my life partner?"

"She is still in hibernation. According to the awake queue, it will take half a year to get it. I'm really sorry for this."

Hearing that nothing had happened to Lin Xuanxuan, Zhang Yuan gradually relieved himself.

"It's okay, it's okay. It's nothing to be more than a hundred years late. "

A week later, Zhang Yuan was discharged from the hospital, took a few deep breaths of air, and then ate a roadside Portuguese grass.

This is a long lost "new year"!

The cabin is no longer deserted in previous years. When I walked out of the hospital, I smelled a strong smell of human society!

There were even a few teenagers aged 15 or 16 who ran by and said hello to Zhang Yuan with a smile.

"Sir, if you just wake up, you need a psychological test."

"Oh... Thank you!"

When he was in hospital, after a side attack, Zhang Yuan had a general understanding of what happened inside the spacecraft, which would lead to the current situation.

The first big thing, someone committed suicide because of severe depression!

In fact, such mistakes are difficult to predict in advance.

The management arranged a lot of psychological comfort work in advance, and also arranged psychologists, thinking that everything could be peaceful. But not everyone is as strong as they think, and a psychologist may not work.

For example, people like Zhang Yuan can explode their liver and be house men. As long as they can learn, they will have the world. He can be alone and entertain himself in a small environment. He won't have a problem for a long time.

Even, in the whole process, there are beautiful girls who are willing to be "life partners"

Anyway, Zhang Yuan's little life is full of flavor.

But there are always others who are social and uncomfortable living in a lonely world.

They endured the most difficult first waking period in pain and difficulty, but they couldn't survive the second and third times. They had no friends and life partners, and they lived a very difficult life.

Depression is a terrible disease. I am depressed and even infectious!

After several suicide accidents, the management was also aware of this. For several consecutive years, they arranged emergency psychological investigation, and actually found many hidden psychiatric patients.
