On a cold morning, Tang Xin leaned lazily against the head of the bed. A household fan in the house emitted a gust of breeze to prevent the entire room from low temperatures. There were only a few sleets in Tianhai City every year, so there were generally no heating systems installed in residential buildings.
With a stack of books in hand, Tang Xin yawned and looked through them one by one. Now his mind was confused by various strange theories.
Recently, he is studying the possibility of traveling through time and space.
Although there is no time and space machine in the four-dimensional pocket, there are other similar props that can go back to the past or travel through the future.
However, Tang Xin was not sure what the consequences would be for time and space travel.
Perhaps it was someone else who had already been sitting happily on the props of time wandering around the future and the past, but Tang Xin was not a person who did things without any consequences after all.
A rough understanding of general relativity and roughly understand the key to traveling through time and space, speed and speed of light, it becomes possible to travel through time and space.
But Tang Xin's thinking fell into a chaotic vicious circle.
Because too many theories have contradictions in the concept of "time".
If Newton's view of time is used as the basis, then the grandmother's paradox is a cautious warning for all those who fantasize about traveling through time and space!
If you travel through time and space and go back to the past and kill your grandmother, then will you still exist?
Hawking used the "time fork" to generate the "parallel universe" to solve this grandmother paradox.
However, a new problem arises again. If you travel back to the past or the future, then it is equivalent to having no connection with the space that exists. Then time and space shuttle will be like tourism and not having connection with the space that exists.
Tang Xin put down the book, raised his head and reached out to pinch Jingming's acupoint, and suddenly felt a lot of sorrow.
Some people deny Hawking's theory, because Hawking defined time, or Newton's view of time, is incorrect in a narrow sense.
The universe is four-dimensional space, and the fourth dimension is time. Humans are three-dimensional creatures. The understanding of time must rise to a higher angle to peek at the fur.
In this four-dimensional space, Tang Xin roughly understood some stakes.
The existence of the present is based on the past.
Therefore, if you travel through time and space to the past, even if you change a small thing, it may cause changes in the history of human beings. Because of the butterfly effect, the longer you go back, the greater the impact, and even accidentally erase the basis of your existence.
History cannot be changed, otherwise it will be in danger now.
Go to the future?
From the macro perspective of four-dimensional space, the future seems to be destined. Looking at it this way, it seems that there is no danger in the future.
But Tang Xin was still in a heavy mood and was not optimistic about spying on the future.
For example, he goes to see the rise and fall of the stock market tomorrow, and then comes back and buys now to make a profit.
Questions still follow. He did not participate in this variable in the future he saw. His intervention will inevitably trigger changes in future trends. Who can guarantee that the stock will definitely rise?
Perhaps his participation is very small, but the whole world is composed of countless small events, the correlation is that humans cannot see or even detect it with their naked eyes. Some such scientists specialize in the chain reaction of complex events.
Thoughts flew back, Tang Xin stroked his forehead distressedly. His four-dimensional pocket was obviously impossible to be a product of modern science. So what would the impact of this pocket on him on the future?
Buzz
The vibrating sound of the cell phone made Tang Xin wake up from his struggles of thinking. When he answered the phone, his gentle face suddenly sneered.
He slowly put on his clothes and looked in the mirror. After Tang Xin was dressed neatly, he left the house and took a taxi and headed towards Xinghua Street.
When he arrived, he paid to get out of the car and stepped on the soft snow. Tang Xin put his hands in his top pocket to keep warm and walked slowly towards the bar.
There were many people gathered outside the bar door, and there were onlookers across the street. A police car was parked at the door, and pedestrians in and out were in a hurry.
Ye Pengfei and Li Shufen talked to the police with a sad face. Fu Yiqun called in a secluded corner. Qiu Qiang leaned on his prince's motorcycle to wrap his arms around his chest, looking coldly watching.
When Tang Xin saw Chang Haitao leaning against the police car, his expression was as normal as Qiu Qiang.
Seeing Tang Xin coming, Chang Haitao's eyes flashed. He looked at him tepidly and looked down from behind. He took out a pack of cigarettes and lit a cigarette and sucked the clouds and mist.
Qiu Qiang came over to greet Tang Xin. Tang Xin smiled at him, then raised his hand to stop him from talking. He greeted him, Ye Pengfei and Li Shufen, and walked into the bar.
It was a mess, and there was no clean area in the entire hall, either fragments or colorful paint splashed with colorful paint. Lin Xue saw Tang Xin with a sad face and hurried over and said, "Tang Xin, this is not our responsibility."
Tang Xin ignored her and patroled around. The bar that was less than half of the decoration was almost ruined, but he seemed to be fine and still had a smile on his face.
Walking out of the bar and coming to Chang Haitao, Tang Xin smiled and said, "Captain Chang doesn't mind sending me a cigarette, right?"
Chang Haitao raised his eyelids slightly, took out a cigarette from the cigarette box and handed it to him, and took out a lighter to light it for him.
After spitting out a smoke ring, Tang Xin waved to Chang Haitao. Chang Haitao didn't know what he was going to do, so he followed him away from the crowd and stood on the sidewalk outside the bar window. Looking into the bar from this angle, you could see a clear mess.
"Captain Chang, is there any suspects in the police?"
Tang Xin asked softly.
Chang Haitao shook his head and said nothing, which was considered an answer.
Tang Xin whispered and said in a low voice: "Captain Chang, Dingwei Security Company has really done too much this time. I will lose at least 500,000 by smashing it. But it doesn't matter. They will give it back to me, and it will be doubled. I'm worried that there is not enough money for decoration."
He looked at Tang Xin in surprise, and Chang Haitao lit a cigarette himself, and looked around invisibly. There were no outsiders within ten steps. He blew up the ashes and said meaningfully: "Tang Xin, you are underage yet. The social rules are not as simple as you imagined. I am very curious. Why did you react when you encounter such a thing? There are countless business people in Xinghua District, so why is your bar closed before it opens?"
Tang Xin's lips curled up to a beautiful curve and said lightly: "I don't resist? Then, like most people, swallow their anger and then vent in private with pale words? Does the United States, which claims democracy the most in the world, rely on words? No, it's an airplane and tank. Captain Chang, I think you are just going through the motions today. Criminals must not be able to go to the sky without missing that sentence. Then I asked clearly, if I don't pay the protection fee, will the business be impossible? Will someone come to smash my store tomorrow and the day after tomorrow?"
With eyes facing each other, Chang Haitao was surprised at the calmness in Tang Xin's eyes at this moment, but he didn't take it to heart. He patted his shoulder like an elder, and said in his ear: "There are rules everywhere in this society. If you don't abide by it, you will be rejected and unable to survive."
"Thank you, Captain Chang for your teachings, I remember."
Tang Xin kept smiling. When Chang Haitao saw that he seemed to have a clue, he walked back and got into the police car and no longer cared about it.
After the police car left, Tang Xin was still standing there, slowly took out a recorder from his pocket, put on his headphones and listened to the conversation with Changhaibiao just now, then looked up at the monitor in the corner of the bar window, and smiled knowingly.
