Chapter 1645 The cloned world is real

What’s interesting is that some people think that “Source Code” is brain-burning, but they can still understand it.

Some people think that "Source Code" is actually very simple, but there are some parts that they cannot understand.

So as the movie was released, many various interpretations and analyses of the film reviews began to appear on the Internet.

"Some people say Source Code is too brain-burning, but in fact, the plot of Source Code is very simple! Just like you need to understand the first five chapters of Dream of Red Mansions, you only need to understand the 33 minutes from 35rd to 2th minute of Source Code to understand the film!
In these two minutes, the professor explained the origin of the source code by explaining two characteristics of the brain. The two characteristics of the brain he interpreted are: 2. Consciousness does not disappear immediately after death; 2. Before brain death, consciousness will leave an indelible and profound memory (afterimage) for 1 minutes.

In short, after a person dies, there will be 8 minutes of memory in the brain that will not disappear immediately. It can be extracted, superimposed, and reconstructed into the last 8 minutes of the deceased's life. After the image is digitized, it forms what the professor calls the "source code." The so-called digitization here may also be understood as the digitization of biological information.

Knowing this, it’s not hard to understand this super simple story:

Lin Yunbin was a soldier who "died" two months ago while returning from a mission by helicopter. He became a vegetable. Note that this is a vegetable, which is very important! The professor used legal means to bring him to the laboratory to maintain his life, waiting to receive a mission to carry out the source code project.

The lame professor waited for two months, and finally a terrorist incident happened. A train was attacked by terrorists and no one survived. The terrorists also released news on the Internet that they would continue to carry out a series of terrorist activities in the city center.

In order to find the murderer, the professor immediately rushed to the scene to collect brain residual images of all the dead, and superimposed the brain information of each person for 8 minutes before his death. Through the digitalization of biological information, he reconstructed a source code that lasted only 8 minutes. Of course, we may wonder that this collection and reconstruction process is a bit too fast, but this is not the point. The point is that this source code shows a virtual world that lasts for 8 minutes. Then the professor found one of the dead, Li Zheng, whose physical signs matched those of his vegetative patient Lin Yunbin. As the source code entrance, he deleted the original memory belonging to Li Zheng and implanted Lin Yunbin's consciousness code so that he could enter the source code to seek the truth. Note that the original memory of Li Zheng has been rewritten or deleted here!
Because it was just a piece of biological source code, the professor believed that everything Lin Yunbin's consciousness did in the source code was just to reassign this period of time in the source code!

Implanting Lin Yunbin's consciousness is also a kind of reassignment. It will not change the established facts of the real world, but it will help to find the real culprit through continuous assignment and reorganization of the source code!

In fact, to put it simply, it is equivalent to "cracking the code" of a computer. Lin Yunbin's different choices and decisions during the code execution are a kind of reassignment and then calculate different results.

But the professor himself didn't know that he had inadvertently opened the door to a new world.

After Chen Juan was rescued and watched himself being hit to death, she must continue to live; Chen Juan was shot to death and it would not be reported that she died in the train explosion; I called the professor in the source code and almost got through.
All these signs made Lin Yunbin, who kept traveling (re-assigning values), slowly realize that after 8 minutes, although the source code had finished running, the world related to the 8-minute run was still going on, and it was different from the real world! These were several different new worlds that were recreated! If he changed the inevitable death of one of the worlds, he might be able to continue to survive in this world.

So he strongly asked the female captain to give him another chance and end his life in the real world after the end. Maybe he was afraid that his consciousness would be pulled back to the real world.

The rest is easy to understand. Lin Yunbin's consciousness changed Li Zheng's fate in the newly created world, and his consciousness was able to continue in him. At this time, there was no train explosion in the new world, so the vegetative Lin Yunbin was still lying in the laboratory waiting for a mission, and the female captain also received a strange text message.

In the text message, Xin Li Zheng hinted to the vegetative state through the female captain that one day, the consciousness of the vegetative state Lin Yunbin would change his own destiny in the creation of a new world, and survive in this world in another form.

Sometimes, being too simple doesn’t make things clear, so I’ll try to explain it more clearly using slightly more complex language:
What exactly is source code and how it is formed is particularly interesting and crucial to understanding this film. Dr. pointed out that the formation of source code is based on two characteristics of the brain:
The first characteristic is that brain waves do not lose power immediately after death. In other words, for a period of time after death, all the information and memories in the brain are the same as before death. When advanced technology is used to maintain power in time, brain information can be extracted and preserved forever.

If we continue to study it, we can easily come to a conclusion that the world of source code is not constructed by the brain information of one person, but by the cross-over and superposition of the brain information of all the dead on the train. This world may not be as complete as the real world, but it is very close to reality. This explains why the world of source code is so colorful, and can call up the memories of the dead long ago, and can connect with the world outside the train.

The second characteristic is that before the power is cut off, the brain waves will gradually strengthen the 8 minutes before death into a deep memory (afterimage). Compared with the various brain information in the first characteristic, this memory is clearer and more substantial. It is enough for the professor to superimpose the 8 minutes of everyone into a very clear virtual world, and easily find Li Zheng's memory in it and clear it.

It must be explained here that Li Zheng's 8-minute memory was definitely cleared, because Chen Juan knew him, but he didn't know Chen Juan. However, as one of the information sources for building the entire source code world, Li Zheng's entire brain information 8 minutes ago is not as profound as the 8-minute memory, so it is not so easy to search and clear. Therefore, every time Lin Yunbin looks in the mirror, he can clearly image Li Zheng's appearance. You know, Li Zheng is someone Lin Yunbin has never met.

Why did they clear Li Zheng's memory? In fact, it was to allow Captain Lin's brain waves to have a relatively matching carrier to operate. He was not really dead, he actually became a vegetable, but his brain was not dead, but he also formed a strong memory before his death, and did not form any memory in the following 2 months, and this memory before death was also cleared by the professor, so he only remembered that he was in the cabin before his death, but did not remember being hit, until someone mentioned it and let him recover his memory - in simple terms, it is equivalent to hard drive data recovery.

The new world created by the source code can last indefinitely. This great discovery was gradually realized by Captain Lin during his many time travels.

The professor probably didn't know that he had inadvertently opened the door to rebuilding a new world. Of course, this is my personal opinion. I personally don't tend to believe that he knew the inside story and deliberately concealed the truth.

When Captain Lin traveled through time for the second time, he began to find that "it was the same train, but a little different". The professor's original intention was to let him find the real murderer in a "low-key" way, trying not to affect others or other things, and even shooting everyone in turn to test who the murderer was if necessary. However, Captain Lin was more high-profile. He "stupidly" interfered with almost everyone's memory and drastically reassigned the source code. He gradually found that the calculation results or the memories of some people had changed accordingly.

The most serious incident was the third time he crossed over, when he followed a passenger getting off the bus with his girlfriend. Since the passenger was not dead, he should not have been within the information source of the source code construction, and his behavior after getting off the bus should have been unknown to anyone. However, due to his reassignment (tracking) of the source code and recording everything he saw as a new memory, he filled in the blanks of the passenger's behavior.

What’s more interesting is that when he was fighting with the passengers, the train exploded, but he did not die in the eighth minute, and Chen Juan’s fate was also changed at the same time.

If he hadn't been accidentally hit by a train, he wouldn't even have died and returned to the real world.

All this (and more signs later) made him realize very clearly that it was not as the professor said that he could not exist outside of Li Zheng's 8 minutes of memory. The professor's premise was that Li Zheng was dead. What if he was not dead? He believed that as long as he was not dead, his brain waves could always exist in Li Zheng.

The formation of this concept was clearer when he returned for the fifth time, and it was quite clear when he begged the female captain to give him one last chance. The termination of Captain Lin's life in the real world was not to prevent the brain waves from returning automatically, but to prevent the professor from manually pulling him back.

Finally, the term parallel world is not strictly speaking appropriate.

It should be said that every time you teleport, a completely new branching world is opened up.

为什么这么说呢？假设第一次穿越是在事发当天下午3点整的话，穿越到的第二个世界是早上7点40整（48分发生爆炸），3点和7点40，很明显在时间上2个世界是不平行的。

Then let's continue. Assuming that the second teleportation is initiated immediately after the first teleportation, the time should be 3:08. However, the third world we teleport to is still 7:40 in the morning. It is obviously not parallel to the first world, and not even parallel to the time and events of the second world.

By analogy, every time he traveled through time, the new world he opened up started at 7:40 and was definitely not parallel to the first world. They were not completely parallel to each other either. It could only be said that they were new worlds branching off from the first world at different time points. Just as he said at the end, they were all different forks in life caused by different choices.

So the bifurcated world is actually a brand new world created when people make different choices at a certain moment. This world clones the world information before this point in time, and then develops freely according to people's choices. It's just that usually everyone only has one choice, but he unexpectedly got multiple opportunities to choose, and in the end he made the right choice. At the end of the film, he said that the professor and his team actually created a new world, which means this - not opening a channel to an existing parallel world or changing history.

In fact, from the technical terms, this movie is also quite interesting. What is source code? A computer application is actually a bunch of binary codes. This binary code is actually a machine language that can be recognized by the CPU. When the application is running, the system loads the binary code of the program into the memory and then gives it to the CPU to recognize and execute. These binary codes are source code.

A process is a running application.

A thread is a single sequential flow of control in a process. A thread is created in a process and performs a certain task. When the task is completed, the thread terminates.

Threads are subordinate to processes, and a process can contain N threads at the same time. These N threads run at the same time until their respective tasks are completed. It can be understood as N cars on the highway, driving forward at the same time, they have different destinations, and they will stop after reaching their destinations.

If you interpret it from this perspective, you will find that it is actually very vivid.

First of all, the whole world is a running application, a process. We all run in this process.

The basis is based on a setting that humans will retain the last 8 minutes of memory when they die. The professors in the movie believe that this 8-minute memory is a piece of source code in the "World" application.

After the train bombing, the professor saved the memory (source code) of a passenger on the train 8 minutes before his death. His idea was to start a thread to repeatedly execute the code of the 8 minutes to find the terrorists and avoid the second bombing in the city center. However, they did not have the ability to create threads and could only use existing threads. Captain Lin died, and only his brain was still active. This active brain is a thread.

Captain Lin's brain (thread) is repeatedly activated to execute the 8-minute source code. Theoretically, after the 8-minute source code is executed, the thread will terminate. Captain Lin's brain will be separated from it and return to the initial state. In the movie, Captain Lin is in a fully enclosed iron box to represent this state.

The professor's theory seemed to be verified in the actual operation, because Captain Lin did return to the initial state after 8 minutes of each mission.

However, the professor was wrong. The reason why Captain Lin returned after 8 minutes of execution was not because the source code for that 8-minute period had been executed, but because Captain Lin died every time, either by being blown up, hit by a train, or shot by terrorists. In the two cases of being hit by a train and being killed, Captain Lin returned only after the train exploded, which was longer than 8 minutes. Therefore, the thread was not terminated by the completion of the source code execution, but by the termination instruction (Captain Lin's death).

So at the end of the movie, there are two worlds (processes) running in parallel, one is the original world, and the other is the cloned new world.

In the original world, the train exploded. In the cloned new world, the train exploded without happening. "
