"Students, we learned a lot in the last class, let's review it again.

Can anyone get up and tell me what we learned about parallel universes in the last lesson? And give extra points to the students who speak, and the extra points will enter the annual selection of the three good students, everyone can raise their hands to speak. ”

Teacher Xinglong wrote the four big words of parallel universe on the blackboard and looked at the students below and said.

He can call the shots when he says this, after all, he is a big man at the level of the teaching director.

As soon as the words were finished, the students who studied well below began to raise their hands very actively, while those students who did not like to study played their own games underneath, after all, this class was not their strong point.

A boy sitting in the second row in front of him raised his hand again, he was not very tall, he thought that the teacher would not find him, but he was seen by Teacher Xinglong.

Because he is a top student, and he is also a representative of the Chinese class, he is also very handsome, and his name is Blue Fox.

"Everyone is very positive, I see it in my eyes and keep it in my heart, and a very few students don't like to speak, and they still make small moves under the table, don't think I can't see it, just let the Blue Fox students get up and set an example for everyone, everyone applauds and welcomes." Xinglong said and applauded, and everyone applauded as soon as they saw it.

As soon as the blue fox heard the teacher ask him to get up, he immediately stood up and said in a loud voice: "Teacher, a parallel universe refers to an existence that is separated from a certain universe and parallel to the original universe.

In these universes, planets with the same or the same history may also have people who are exactly the same as humans.

At the same time, things will develop differently in these different universes, for example, species that are extinct in our universe are in another universe and may be constantly evolving and evolving.

The two universes that are parallel to each other neither coincide nor intersect, and it can be said that "the water of the well does not interfere with the water of the river."

Although through some fortuitous events, the two universes are able to perceive each other's existence; Teacher, I'm done. ”

"That's a good point, I'll give you 10 points, but keep working hard, the teacher is optimistic about your good results in the final exam." As he spoke, Mr. Xinglong wrote his name on the blackboard and added ten points to it.

"Thank you! Teacher, I will try to show you, please rest assured. As he spoke, he moved his chair forward and sat down, his legs together, his hands on the table in the shape of a thousand layers of bread, and his waist straight.

"Excellent! Everyone is going to sit like this with the blue fox, and now it's all for me. After seeing his series of actions, the physics teacher tapped the table with a ruler and said solemnly, not giving everyone a hippie smile.

As soon as everyone dared to make other small movements, they immediately got up and sat down, because they were afraid that the teacher would read their names.

"Who else knows? You can give me a hand. ”

The students below saw that there were extra points, which means that the teacher was serious, and began to raise their hands high for fear that the teacher would not see it.

"Teacher, I'll tell you ......"

"Teacher, I'll talk about ......"

"Teacher, I'll just come......"

"Okay, let Sun Um answer the question." Physics teacher Xinglong didn't name anyone, but saw the boy in the middle of the third row and said.

When Sun Mingyou heard this, he quickly stood up and didn't read the textbook and said: "Parallel universes refer to being in the same space system, but the time system is different, just like two trains speeding on the same railway line;

They may be in the same time system, but the spatial system is different, like a car driving in the upper and lower passages of an overpass at the same time.

Teacher, I'm done. ”

"Well, that's good, and I also add ten points to Sun Youyou." Xinglong said and added ten points to the blackboard after his name.

At that moment, there was a snoring sound from behind, which the whole class heard, and everyone was looking for who was snoring.

Soon, the teacher can see far away from the podium, he knows everything off the field, just turn a blind eye, as long as the other party does not make things bigger, he will not trouble others.

But he saw Liuying, who was sitting at the end of the sixth row, lying on the table and sleeping, and it was he who was snoring.

Liuying fell asleep because he played the game for too long last night and stayed up late.

Xinglong was very angry when he saw it, he hated it most when someone talked and slept in his class.

But he didn't ask him to call Liuying, because he wanted Liuying to know the lesson.

So he picked up a blackboard eraser from the lectern and threw it in his direction, it was so fast that he believed that his blackboard eraser could hit the target.

But his wishful thinking didn't work, and just as the blackboard eraser was about to reach the top of his head, a hand quickly stretched out from the desk and took it to his hand.

When they saw this scene, all the teachers and students in the audience were stunned, and soon everyone applauded for this small battle, after all, this wave of operations is not something that ordinary people can do, and it requires good hearing and hand speed.

"Shadow, Shadow. Get up! A sound sounded, and it was his tablemate An Ran calling him, and shaking him with his hand.

Shadow opened her eyes and stood up, stretching.

When the physics teacher saw him doing this, he was very angry and said to him, "Liuying, don't you know that sleeping in class is wrong?" Even if you don't listen to the class, you can't lie on the table, which is very disrespectful to the teacher. ”

"Teacher, you are mistaken, I didn't sleep, in fact, I was lying there listening to your class."

Liuying looked at him and said, pretending that he wasn't sleeping.

However, the teacher and classmates did not say anything, and several things about him were exposed by themselves.

That is, there are marks on his face that he has slept, and he wipes the hara from his mouth with his hand before getting up, and he is being shaken by the person next to him.

"I heard you right, are you listening to my class? The point is that you're snoring, and anyone can hear that. As soon as Teacher Xinglong heard that he still had a rebuttal, he told a little truth.

"Actually, I'm pondering how parallel universes can appear? I think my classmates are speaking very well, so I made a sound, and I am sorry for what happened to me just now. Liuying said apologetically.

"Didn't you say you were listening? If what you say is right, then the teacher will sit you down, and if you say something wrong, then how about you stand and listen to a lesson? Xinglong looked at him and said.

"This is what you said, you can't go back, you have to call the shots." Liuying was afraid that he would regret it, and hurriedly said.

"Well, that's what I said. A gentleman's word, a quick horse. Xinglong nodded, in fact, he wanted to see what Liuying said.

"Okay, then you ask, I'll answer." Said the teacher who looked at him.

"Listen, what does it mean to explain parallel universes?"

"Uh...... Parallel universes? Sure enough, Liuying looked a little blind, and scratched his head anxiously, his mind racing rapidly.

"Haha! Fight with me, it's still a little tender. Teacher Xinglong laughed in his heart, but he didn't show it, because he saw Liuying's sad face.

"Teacher, do you really want me to say it?" He didn't answer the question but asked him about the teacher, he wanted to see if what the teacher said was true or false.

"Of course, if you don't want to answer, do you still want me to answer as a teacher?" The teacher looked at him and said.

"Then you see! According to Einstein's theory of general relativity, there are other parallel universes outside of this parallel universe where we exist, and these universes are strikingly similar to each other.

For example, in another parallel universe, there may be someone who looks exactly like you.

However, we can't travel through these parallel universes unless we do it through wormholes, but according to the general theory of relativity, these wormholes have a great attraction and can destroy all foreign matter, so it is almost impossible to travel through time and space through wormholes. ”

He sat down without waiting for the teacher's surprise, because everything he said was right, and some of them hadn't even been printed yet.

These are all big topics that scientists are working on right now.

The teacher and his classmates who didn't look at him well were shocked, they didn't expect him to speak so well, so completely, and there was no mistake at all.
