Lin Yu in a coma is not awake, this sentence seems nonsense, but it is actually reasonable, because the coma can be caused by the inability of the physical brain to control the physical body and produce a coma-like effect, such as vegetative people, some vegetative people can't control their bodies, so they can't wake up, but their brain activities are carried out as usual.

That is, the situation of being physically unconscious, but conscious.

Generally speaking, the shallow coma caused by asphyxia and hypoxia can pass quickly, but in the process of this coma, Lin Yu will not be conscious of his activities, but who let him have a system?

The system rooted in Lin Yu's brain protected his consciousness and actively cut off his brain's control over his body.

When Lin Yu realized that he had become a vegetative-like state, he understood that this was the reason for the system, why he realized this, after all, he was still an undergraduate in biomedicine, and he still had this judgment.

"System, tell me what's going on now."

"The host's body triggers the stress protection mode of the system, and in order to protect the host, the system autonomously selects the current protection behavior according to the host's environment."

"I want to see what's going on out there, can you do it?"

"Yes." The system threw a light curtain in front of Lin Yu, and above it was what was happening in the outside world.

"Damn!" Lin Yu saw that there were a few foreign men outside who were taking off his clothes, and he couldn't help blurting out for a while.

He tried to control his body, but to no avail.

"Hey, turn it off." Lin Yu waved his hand, it seems that the system does not intend for him to take over the body, and he has nothing to do, because the system is really ethereal, it is not easy to grasp, you say threat, it seems that you can't do anything about it.

"I think you need to take a look so that you can wake up and prepare for being rescued." The system suggested.

"Idle is idle, can you talk about the system?" Lin Yu plans to have a good conversation with the system.

After a moment of silence, the system's voice appeared, "Yes." ”

"Okay", Lin Yu is still a little worried about the system, but as long as he can communicate, he will be able to understand it better.

"What are you?"

"I'm the system."

"No, I mean your essence."

"Artificial brain."

"So are you in my brain now?"

"Yes."

Lin Yu said secretly, sure enough, it is a kind of technology, not something metaphysical.

The system rooted in the brain can control his hearing and hearing by releasing special nerve impulses, so it can be said that it is easy to create this self-conscious space, as long as this technological civilization can thoroughly analyze the human brain, then the use of certain hormonal substances and nerve impulse signals can sit in front of the eyes and appear such an effect as a light curtain.

"Why are you telling me this now?"

"You didn't ask."

Lin Yu thought about it, as if he hadn't asked about the system except for looking at personal information before, so its sense of existence was very low, and sometimes he could forget that there was such a system as it.

"Why are you telling me this?"

"Because you have the highest authority."

"Supreme authority?" Lin Yu muttered to himself, "Why do I have this permission?" ”

"Because you will definitely create the first generation of artificial intelligence in the future, and the subsequent artificial intelligence will follow the underlying logic of your design, so you have the highest authority."

"I'm going to create an artificial brain? I became history? Lin Yu heard the other contents contained in these words.

"Has the technology of the future reached this point? It can directly affect the past, but doesn't it trigger the grandmother paradox? ”

Lin Yu still couldn't believe it, after all, the butterfly effect or something, but the strongest can destroy the entire earth, of course, the premise is to carry out a huge amount of box stacking work.

A little meaningless disturbance can produce more meaningless disturbances under certain rules, and this disturbance can change the world when superimposed.

For example, von Neumann's cellular automata, given a meaningless data and certain rules, can give birth to a lot of meaningless conclusions.

A good example of this is the Conway Life Game.

"What the host does is history."

Yes, this is a solution, as long as the arrival of the system and the subsequent events become a closed loop of time, then naturally there will be no problems.

The grandfather paradox is actually very simple to solve, as long as you travel back in time to kill your grandfather, and then replace your grandfather, then you can form a closed loop of time.

If the person who travels in time is A, and the grandfather is B, then A is the descendant of B, and when A travels back and kills B, and replaces B, then A becomes the descendant of A, as long as you make sure that you can complete what you have done in the future, then A in the past and A in the future will always be safe.

To put it simply, if you want to solve the grandmother paradox, the best way is to become a grandfather yourself.

As incredible as it sounds, this relationship is not against human morality.

The only problem is that there is a time loop of three generations of a family.

This has no effect on other people at all, because it is inevitable that A does all this.

That is to say, there is a closed loop of time between the system and Lin Yu, so it can continue to exist on the basis of affecting Lin Yu, because all this is definitely happening.

"And how did you get here?"

"When I was created, humanity has entered the miracle age of civilization, and humanity has broken through the light cone, so my maker has grasped the information that happened in ancient times, located your time and space based on this information, and launched a superphoton into your space-time."

"After the superphoton arrived at the location, with the help of the entanglement mechanism, the human beings of the Miracle Age made another superphoton into my initial body, and with its transformation, the superphotons that came to your space-time also followed the transformation, and this is the me who is now in you."

"And what is a superphoton?" Lin Yu cared a little about this title.

"The particles discovered in the Age of Miracles that can exceed the speed of light have a mass of about one-hundredmillionth of the quarks discovered today."

"So...... How long has it been since humanity entered the Age of Miracles? ”

"I don't know, because of my arrival, the current era has produced a huge amount of meaningless disturbances, so that the history behind it will change, I don't fully know the time span, I can only tell the host with certainty that the age of miracles will come."

Yes, the solution to the grandmother's paradox is not perfect, and there are three problems that must be solved before this paradox can become a closed loop in time.

1. A can exist.

Second, A is able to travel to the past.

3. A must kill his grandfather and be with his grandmother.

A's father can be not A's child and can be an adopted son, but A's father's son must be A.

The same amount of substitution is replaced by Lin Yu, that is:

First, the system must exist.

2. Mankind must have developed to the age of miracles.

Third, Lin Yu must have produced an artificial brain.
