dream pocket

In the cold morning, Tang Xin leaned lazily on the head of the bed, a household heater in the house emitted a gentle breeze to keep the whole room from the low temperature invasion, Tianhai City only had a few sleet rains during the coldest time of the year Therefore, residential buildings generally do not have heating systems installed.

With a stack of books in hand, Tang Xin yawned and flipped through them one after another. Now his mind was confused by all kinds of whimsical theories.

Recently, he is researching the possibility of traveling through time and space.

Although there is no space-time 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 is not sure what the consequences of time travel will be.

Maybe someone else would have been happily wandering around the future and the past with the time prop, but after all, Tang Xin is not a person who does things recklessly.

A general understanding of general relativity, and a general understanding of the key to traveling through time and space, speed, when traveling faster than the speed of light, traveling through time and space becomes possible.

But Tang Xin's thinking fell into a chaotic cycle.

Because too many theories contradict the concept of "time".

If Newton's view of time is used as the basis, then the grandmother paradox is a warning that all those who fantasize about traveling through time and space must be careful!

If you travel back in time and space and kill your grandmother, will you still exist?

Hawking used "time bifurcation" to generate "parallel universes" to solve this grandmother paradox.

However, a new problem has emerged. If you travel back to the past or the future, it is equivalent to having no connection with the space of your own existence. At that time, space travel is the same as traveling and sightseeing, and has no connection with your own space of existence.

Tang Xin put down the book, raised his head and stretched out his hands to pinch the Jingming acupoint, suddenly feeling a lot of melancholy.

Some people have rejected Hawking's theory on the grounds that the time defined by Hawking, or that Newton's concept of time is narrowly incorrect.

The universe is a four-dimensional space, and the fourth dimension is time. Human beings 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 relies on the past.

So if you go back to the past through time and space, even if you change a small thing, it may change the history of the entire human being. Because of the butterfly effect, the longer you go back, the greater the impact, and even accidentally obliterate the basis of your own existence.

History cannot be changed, otherwise the present is in jeopardy.

What about going to the future?

From the macroscopic perspective of the four-dimensional space, the future seems to be doomed. Looking at it this way, there seems to be no danger in knowing the future.

But Tang Xin still has a heavy heart, and he is not optimistic about spying on the future.

For example, he goes to see the ups and downs of the stock market tomorrow, and then comes back to buy now to make a profit.

The problem is still coming one after another. In the future he sees, there is no such variable as his participation in it, and his intervention will inevitably lead to a change in the future trend. Who can guarantee that the stock will definitely rise?

Maybe his participation is very small, but the whole world is composed of countless small events, the connections of which are invisible or even imperceptible to the naked eye, and there are such scientists who specialize in the chain reaction of complex events.

Thoughts flew back again, Tang Xin stroked his forehead in distress, his four-dimensional pocket obviously couldn't be a product of modern science, so what kind of impact will this pocket have on him in the future?

buzz

The vibrating sound of the mobile phone made Tang Xin wake up from the struggle of thinking, and when he picked up the phone, a sneer suddenly appeared on his gentle face.

Putting on his clothes slowly, and looking in the mirror, Tang Xin left the house after he was dressed neatly, took a taxi and headed towards Xinghua Street.

When he arrived, he paid and got out of the car, stepped on the soft snow, Tang Xin put his hands in his coat pockets to keep warm, and walked slowly towards the wine.

A lot of people gathered at the Jiumen Exchange, there were crowds on the other side of the street, a police car was parked at the entrance, and people came and went in a hurry.

Ye Pengfei and Li Shufen talked with the police with sorrowful faces, Fu Yiqun was on the phone in a secluded corner, Qiu Qiang leaned on his prince's motorcycle with his arms crossed, and looked on coldly.

When Tang Xin saw Chang Haitao leaning against the car, his expression was as usual, just as indifferent as Qiu Qiang.

Seeing Tang Xin approaching, Chang Haitao's eyes flickered, he looked at him tepidly, then lowered his eyes, took out a pack of cigarettes and lit a puff.

Qiu Qiang came over to greet Tang Xin. Tang Xin smiled at him, then raised his hand to stop him from opening his mouth to speak, greeted Ye Pengfei and Li Shufen himself, and walked into the wine.

It was a mess, there was no clean place in the whole hall, or debris or colorful paints, Lin Xue saw Tang Xin with a sad face, and hurried over and said: "Tang Xin, this, this It's not our responsibility."

Tang Xin ignored her and looked around. The wine, which was less than half decorated, was almost in ruins, but he seemed to be all right, still smiling.

After getting out of the wine and coming to Chang Haitao, Tang Xin smiled and said, "Captain Chang, do you mind giving me a cigarette?"

Chang Haitao raised his eyelids slightly, took out a cigarette from the cigarette case and handed it to him, and also took out a lighter to help him light it.

Breathing out a smoke ring, Tang Xin waved to Chang Haitao, Chang Haitao didn't know what he was going to do, followed him away from the crowd, stood on the sidewalk outside the wine window, looked into the wine from this angle, just happened to be able to see clearly The messy color.

"Captain Chang, are there any suspects in the police?"

Tang Xin asked softly.

Chang Haitao shook his head and said nothing, it was an answer.

Tang Xin chuckled in a low voice, and said in a low voice: "Captain Chang, Dingwei Security Company has really overdone it this time. They smashed it, and I lost at least 50 yuan. But it doesn't matter, they will return it to me. And it has to be doubled, I am worried that I don’t have enough money for decoration.”

Looking at Tang Xin in surprise, Chang Haitao lit a cigarette again, and looked around secretly. There was no outsider within ten steps, he flicked the cigarette ash, and said meaningfully: "Tang Xin, you haven't done it yet. As an adult, the laws of society are not as simple as you imagined. I am curious why your first reaction is to resist when you encounter this kind of thing? There are countless businesses in Xinghua District, why is it that your wine has not Opening is about to close?"

The corners of Tang Xin's mouth turned up into a beautiful arc, and he said lightly: "I don't resist? Then I will be like most people, swallowing my anger and venting it with pale words in private? Does the United States, which is the most flamboyant in the world, rely on words? ? No, it’s an airplane tank. Captain Chang, I think you’re just going through the motions today, and criminals definitely won’t be able to access Skynet. Does it mean that the business cannot be done? Does it mean that tomorrow, the day after tomorrow, someone will come and smash my shop?"

Looking at each other, although Chang Haitao was amazed by the calm look in Tang Xin's eyes at the moment, he didn't take it to heart, patted him on the shoulder like an elder, and whispered in his ear: "In this society, there are rules everywhere. If you don’t comply, you’ll be ostracized and you won’t be able to survive.”

"Thank you Captain Chang for your teaching, I will remember it."

Tang Xin kept smiling, and Chang Haitao saw that he seemed to have opened his mind, so he walked back and stopped caring when he got on the police car.

After the police car left, Tang Xin still stood where he was, slowly took out a recording pen from his pocket, put on the earphones to listen to the conversation with Chang Haitiao just now, and then raised his head to look at the monitor in the corner of the wine window , with a knowing smile.
