Xueba system prevents me from moving bricks

The following is two children who blame each other for making themselves look ugly on the scene, and talk about each other, but they don't make any noise.

*** Open Time and Space

"Okay, the previous topic is over, next, our next topic is opening time and space.

Some people will enter the time-space lock after death, and live the life of that day forever. Of course, this is a relatively closed time-space. Some people will trigger a new time-space line after death, and travel back to the past. "

Li Ning listened, like what happened to him.I just wanted to ask a question, asking the old professor how he escaped from this ghost place. Although he didn’t keep going back to a certain day, he didn’t want to stay in this ghost place for a moment. Even if he met some interesting people, but after experiencing it again, The pain is also doubled. Although he can no longer feel disgusted after a year of system training, he definitely can't say that he likes this point in time.

I was just about to rush to ask questions, but I didn't expect that a kid would take the lead.

He can only wait for the event to be held, and he will personally find the old professor to open a small stove to teach him some experience.

Of course, it is possible that he has no experience at all, and it is more likely that he regards himself as an experimental subject.

"Hello, teachers,"

In the second row, a student who looked like a college student stood up and asked questions to several people in the venue. Li Ning saw in his eyes that he was a young man in a hurry.

"So, professor, can you think that those legends in the past may be true, that there really are [-] levels of hell similar to eternal suffering, and people who fall at a specific time and space point in time and space are like a small building? The small universe does not violate the rules of the outside world. This is also the basis for their existence."

Pull it down, Li Ning doesn't believe this kid's words, he is an example.

Professor Wang Dechun still leads the topic in the lecture.

"The student who asked the question, the point of view you mentioned is very interesting. Sub-universes exist independently, but it is not known whether they can exchange information or even exchange material bodies with our universe. After death, a new timeline will also be triggered. Some People will trigger the new space-time closed loop and stay in it forever, we call them prisoners. These people experience a fixed day 24 hours a day, never stop. Of course there may be breakthrough points, this is our science fiction part, currently There's no theory that works."

"Next, let's talk about the next one!" He said, he didn't want to answer the child's question anymore. The question of the closed universe deviated from their original topic. He originally wanted to focus on the following about the open universe. Going back to the past can change For the content of future history, the following is the best part.

"According to our current sci-fi assumptions, creating a space-time machine requires supercomputers to provide computing power." A guest talked about this topic.

Another person immediately picked up the topic.

"I actually think that the clock of the time machine is the most important part. If a person can go back in time, I think that the clock of the time machine is the key to a person's ability to go back to the precise past. The traveler must set the correct time Only then can it return to the precise time point, otherwise it will be lost like a blind man. The clock device on its body is the key, the accuracy must be very high, accurate to infinite digits after the decimal point." An old man took the words.

"If you can know what's inside without opening the package, then it means you are a space-time traveler." The past and the future are not a purely linear relationship, and it doesn't have to continue from the past to the future. There are multiple intersections in time and space. Points intersect each other and interfere with each other. Some things are like stones in the river that you have to pass through, while some time and space events can be detoured. "It was proposed.

But without opening the box, is the cat inside alive or dead?Can we know without looking?But if it is not a person of this world, he knows that the fact does not seem to violate the laws of the world, because he has seen it, he is from the future, and the world has collapsed in front of him.

Professor Wang likes this point of view very much, and he wants to use this point of view to leave some thoughts for everyone at the end of the meeting.

"You guys always discuss technical issues that we are not interested in. In my opinion, the topic of human-computer interaction interface is the most attractive to our folk science fiction literature. Is the time machine a little girl or a boy?" A science fiction writer said , causing the people in the seats to laugh out loud, feeling that a person is a bit indecent.

"Oh, don't laugh!" Seeing this, he hurriedly explained, "This is a very serious topic. The human-computer interface has always been very important, even related to the life and death of the operator. Think about it, many industrial equipments are caused by the reaction of technicians. Operational accidents are caused by human design. You can’t expect a technical worker to face the set of black switches and red and green light bulbs you invented all day long. There are no other display interfaces, and you can’t expect him to put on a smiling face every day. Is the mask going to work? A pain mask is coming out!"

It was fine if the writer didn't explain, but when he explained it in line with his unique local accent, the audience laughed even harder.

He didn't say anything more.Why!The quality of this audience is not good, tell him serious things, he thinks you are telling him a joke, tell him a joke, he thinks you are telling him a bedtime story.

Seeing the good response from the audience, Professor Wang was very happy, and would like to invite this big baby over next time there is an event.When the audience became quieter, Professor Wang stopped smiling and said:
"Everett's multi-worlds interpretation of quantum mechanics points out that our universe is just one of the universes. One thing that is happening, all possible subsequent results will collapse into one universe alone. I will take a step forward immediately. , or two steps, there are different answers in different universes." Professor Wang said, stood up and took a step forward in the venue, then retreated, "Well, this world is one step." He smiled .

……

*** Epilogue: Invitation Letter
Finally, the end is coming to an end, and the professor wants to end today's symposium with a brief summary.

"Next, I will complete the last activity of this sci-fi symposium. I also learned from the conversation with you just now. I haven't told anyone about this activity, including all the guests present..."

At this time, a voice suddenly came from a long distance behind Li Ning, speaking loudly, interrupting Professor Wang.

"Please, professor, don't talk about unanswered questions. We are not elementary school students anymore." A young man in the last row raised a microphone to question Professor Wang and science fiction master Yue Wenfang. The young man was dressed in black and his face was covered The head was wrapped in a black cloth, making it difficult to recognize his face, and he sneaked into the venue at some point.

It seemed that apart from Li Ning and Liu Ting, there were no other primary school students present.Li Ning felt very uncomfortable listening to him. Everywhere he went, he was said to be a primary school student and was looked down upon by others. Primary school students are also very strong!However, he remembered the days when he was cheated by elementary school students while playing games, and suddenly felt that what he said was right, and his point of view was clear and logical.

"Science proposes a theory that requires verifiable methods and experiments. Otherwise, it cannot be called science if it does not find a method to prove it. The same is true for science fiction. Although you are asked to relax, you still need a way to prove your What you said is not a series of lies. So the professor proves it!" The overwhelming aura of the young man Taishan put a lot of pressure on the professor.

The young man's point of view is good, but his behavior is a bit strange, which Professor Wang doesn't mind.

"Little comrade, how do you think we should prove it?"

"It's very simple, if any of you here has never been here, first rely on him to prove that he is from the future..."

"How does this prove?" someone questioned.

"It's very simple. He must have some thoughts and behaviors brought from the future. He can regard people as a machine, and he walks in this world by this. His behavior and thoughts will reveal the foresight of the future. Simply put, he He has, so he knows the answer."

"Hey hey hey..." Someone was dissatisfied and said a lot of nonsense, just say no to the last sentence.

"Then if he doesn't want to tell the truth, he just tells lies? How can you tell?"

"Yes, the reverse proof is not feasible, and we can only force it forward. Space-time has its own rules, and people cannot surpass the laws of physics. Some laws of space-time guarantee..."

Professor Wang interrupted him, "Little comrade, let's talk slowly later, now, let me finish the last part of this event, okay?" He smiled kindly as a scholar, meaning Get out of the way, little guy, don't disturb the order of the venue.

"Professor Wang Dechun is going to send letters to those future time travelers at the end of the symposium, so that they can participate in this conference?" The young man smiled sinisterly, and Li Ning saw his aura The strange eyes wandered in the hall like ghosts, looking for prey.

I saw Professor Wang's gloomy expression, staring at his eyes, except for his eyes, he covered everything tightly.

"How do you know, even they don't know! How do you know? Who are you?" He pointed at all the bosses present, and then Professor Wang was stunned, unable to concentrate for a long time.

The audience applauded immediately, and everyone thought it was the effect of the show.

"Old Wang acted like that!"

"Yeah, you fooled me!"

……

Spectators left the arena, pouring out both the front and back doors.

"Hey, don't go away! There are people in your group who come from the future!"

He pulled the floating people, and everyone smiled at him, implying that he played well.

"I'll find you, Time Traveler!"

This guy isn't coming towards him, is he?Seeing that something was wrong, Li Ning quickly slipped out without even having time to say hello to Liu Ting.

But he didn't go far, staying in a dark corner outside the museum, staring at the people passing by.

He did have some questions he wanted to ask Professor Wang, but now that mysterious young man attracted his attention.
