My girlfriend died in the past

Chapter 58 The Possibility of Time Travel Back

After I arrived at the hotel and knocked on the door, the person who opened the door was a slightly plump man in his thirties.

He was wearing a short-sleeved T-shirt and casual shorts, and a pair of flip-flops. He looked nothing like the physics PhD that Zhuang Xiao had in mind.

"Boss Zhuang, I said I would visit you tomorrow."

As soon as he saw Zhuang Xiao, the man immediately extended his hand enthusiastically to shake hands with Zhuang Xiao, and then let the three of them into the house.

Compared to the two beauties Shu Die and Dong Weirui, he looked at Zhuang Xiao with particularly fiery eyes.

"Um, what's your name?" Zhuang Xiao felt quite uncomfortable after sitting down.

Why does this brother look so weird?

"Just call me Fisherman. I'm used to using a pen name. It takes me a long time to react to my real name." The physics PhD and science fiction writer, who goes by the pen name Novice Fisherman, was very enthusiastic.

This is normal, because he came here to take a deposit of 500,000 yuan! If the cooperation is satisfactory, there will be a balance of 500,000 yuan later!

It would be strange if he wasn't enthusiastic towards the financial sponsor!
"Hello, Doctor." Zhuang Xiao decided to just call him "Doctor". It always felt weird to call someone a fisherman.

"Okay, whatever you want." Dr. Fisherman didn't care, but asked, "Just now I received a message from your secretary saying that you are planning to discuss the world view setting of the game now, right?"

"Yes, I don't know much about time, I just have the story framework." Zhuang Xiao really didn't understand.

"First, we need to understand the concept of 'time' itself." The doctor asked, "Mr. Zhuang, how much do you know about time?"

Zhuang Xiao was very honest, "I know there are 24 hours in a day."

".Excellent insights!" The doctor snapped his fingers, "But I need to add a little more."

He thought for a moment, thinking about what simple and easy-to-understand method he could use to make the young boss in front of him understand the basic principles without offending him.

“The concept of ‘time’ is relatively abstract. To put it simply, it is a parameter that we humans use to describe the process of material movement or the occurrence of events.

"To put it more concretely, concepts like 'the period of the Earth's rotation' or 'the period of the Earth's rotation around the Sun' are observed by us humans as related physical phenomena, and we call them 'days' and 'years'."

Before Zhuang Xiao could say anything, Shu Die suddenly realized, "So 'time' doesn't exist at all?"

"No, time does exist, but forget it, let's not talk about this topic." The doctor hesitated and finally gave up explaining.

Zhuang Xiao breathed a sigh of relief.

Thanks to Xiaodie, he had originally thought so too, luckily Xiaodie took the blame.

The Doctor was also sweating a little.

It is really difficult to discuss professional matters with a complete layman in a simple and clear manner.

But there's nothing we can do about it, since he's the financial sponsor.

He simply got straight to the point, "Let's talk about 'time travel'."

Zhuang Xiaolai was very excited. "Please speak."

The doctor asked seriously, "Do you believe in gravity?"

"Isn't this the line from the sixth part of JOJO?" Shu Die muttered softly, but her voice could be heard by everyone in the room.

"Well, that's it." The doctor almost couldn't hold it back, so he changed the subject again, "Do you know 'time paradox'?"

"I know this. I have seen many science fiction movies with similar themes." Zhuang Xiao nodded.

"Back to the Future", "Time Paradox", "Tenet", "Source Code", "The Butterfly Effect", "Terminator" and so on, these movies are more famous than one. The doctor then smiled reservedly, "Yes, but science fiction movies are just as the name suggests, they refer to 'science fiction' movies, they are just fantasy after all.

"Are you familiar with the 'Grandfather Paradox'?"

"I know." Zhuang Xiao nodded. "If a person goes back in time and kills his grandfather before he gets married, then neither his father nor he will exist. Since he will not exist, he cannot go back in time and kill his grandfather."

"In fact, it's more than that. Strictly speaking, the moment this man's grandfather is killed by him, the whole world will disappear."

Seeing that Zhuang Xiao and the other two were puzzled, he explained, "Because at the moment of Grandfather's death, everything related to him would change, including the people he knew or his relatives and friends, even the owner of the breakfast stall where Grandfather went downstairs to eat once and the owner of the tobacco shop where he bought cigarettes.

"The 'future' of these people no longer exists, so they naturally don't exist either. Based on them, the connection between them and this world spreads out. The final result is that from the moment my grandfather died, the future of this world no longer exists."

The doctor snapped his fingers. "Similar to this, there are other little pieces of knowledge that are easy for laymen to understand, such as the 'suicide paradox', the 'coffee paradox', and the 'prophet paradox'."

The suicide paradox means that if a person goes back to the past and kills his past self, he will disappear, but since his past self is dead, his future self will not exist either, so a non-existent self cannot go back to the past and kill himself. This is similar to the "grandfather paradox".

The coffee paradox means that if a person drinks a cup of poisoned coffee, he contacts his past self through some method before he dies from the poison and tells the other party not to drink the poisoned coffee in the future. The past self who received the message follows the advice and does not drink the poisoned coffee.

So the question is, if he didn't drink that cup of coffee, how could he have sent a message to his past self?
The prophet paradox is similar.

This means that if something happens to a person, and then he goes back to the past to change the outcome of that thing, for example, if that thing is "Event A", and after he changed "Event A" it did not happen, but became "Event B", then it is impossible for this past person to have "Event A" happen in the "future", so it is impossible for him to go back to the past and change "Event A".

Zhuang Xiao's voice was a little hoarse. "So, a person can't travel to the future, because the 'future' hasn't happened yet. At the same time, he can't go back to the past, because things that have already happened can't be changed."

So how do you explain what happened to him?
Shu Die curled her lips and said, "Then can we not make this game?"

"It can be done! Of course it can be done!" the doctor immediately retorted.

What a joke! This is a big money sponsor! He is still waiting to get the subsequent consulting fees!

As a consultant, isn't your job to first raise a problem and then provide a solution? Otherwise, what if people say, "It seems like you didn't do anything" and then stop paying you?
It's just like going to the dentist.

The doctor says that your tooth is difficult to extract and it is very serious. Then he removes it with a few clicks and says the operation was a success. At this time, you can only be grateful.

But it seemed that he had used too much force this time and had to make amends quickly.

"Boss Zhuang, let me ask you first, is there a parallel world in our game setting?"

Zhuang Xiao shook his head. "Let's not consider parallel worlds for now. The world before and after is the same."

"Then I think we can use the principle of time jump to justify ourselves." The doctor snapped his fingers.

Zhuang Xiao perked up, "What do you mean?"

The doctor smiled and asked, "Mr. Zhuang, you should know the law of cause and effect, right?"

"There are three schools of Japanese mahjong. In addition to the 'Law of Cause and Effect', there are also the 'Teppodama' and the 'Royal Warrior'!" Shu Die continued.

PhD:"."

Zhuang Xiao glared at her, and Shu Die smiled awkwardly and retreated, "I just thought the atmosphere was too tense, so I wanted to relax a little. Okay, I won't interrupt anymore."

Seeing that she was honest, Zhuang Xiao said, "You reap what you sow, isn't that right?"

"Yes, because everything has a cause and an effect, that's why the time paradox is triggered, so why don't we just avoid it?" The doctor smiled.

Zhuang Xiao became excited and asked, "Tell me more!"

Maybe the reason why he can go back in time can be found here!
