What made Yan Xiuze unbelievable was that the old man in front of him, who looked to be at least in his fifties, actually looked exactly like the instructor!

No, it can't be said to be exactly the same, for some reason, the instructor looks much younger than this Professor Zhou, there is no gray hair in his temples, and he has been tied in a ponytail for many years, looking like a fairy who has walked out of the fairyland......

But now, how did he become such an old man?

If it weren't for the teacher-student relationship with Bai Xuyan, Yan Xiuze would almost have mistaken the one in front of him for the instructor's father!

Moreover, Yan Xiuze also keenly discovered that the red rope that the instructor had been using to tie the horse's tail in the original world actually ran to his wrist at this time, and he didn't know what the commemorative significance of this red rope was...... It was so that the instructors of the two worlds invariably carried it with them.

"Instructor?" Professor Zhou tilted his head a little puzzled, then looked at Yan Xiuze and said curiously: "This is ......?"

"Teacher, you must be very interested in his origins." Bai Xuyan stepped forward at this time and explained, "Do you know that there is a superpower named 'Colonel Storm' in Huaxia Country? ”

"Well, I think I've heard of it...... Wait, this ......" Professor Zhou's eyes widened, as if he had suddenly discovered a new continent: "I seem to have seen a picture of Colonel Storm before, and this one seems to be ...... Like? ”

"Teach...... No, Professor Zhou, hello. Yan Xiuze took a deep breath and said slowly: "I am also Yan Xiuze." ”

"Also?" Professor Zhou stood up from the rattan chair with some excitement: "What do you mean......"

"That's right, I ...... From another world. ”

Looking at the instructor with an old face in front of him, Yan Xiuze said with a complicated expression, he had always thought that the real age of the instructor was only in his thirties at most, but he didn't expect that just because the instructors in the original world were too well maintained, he was actually an old man in his fifties.

"Do parallel worlds really exist?" Professor Zhou said excitedly: "Hurry up, tell me the ins and outs of the matter!" ”

……

"That's the way it is...... In our original world, Bai Xuyan relied on the space-time wormhole created by the antimatter explosion to suck me, Bai Xuyan, and Melson into it at the same time, and then when I woke up, I was already in this world. Yan Xiuze explained for half an hour before finishing everything, and he looked at the instructor in front of him, hoping that he could get inspiration from his own story and give him hope of going home.

But after listening to all the narration, Professor Zhou was rarely silent, his right hand kept rubbing the stubble on his chin, while his left hand kept slowly stroking the red rope tied to his right wrist, as if he was in a long thought.

Just when Yan Xiuze and the others were already waiting a little desperately, Professor Zhou suddenly spoke: "No, it's not a space-time wormhole. ”

"Huh?" Yan Xiuze was stunned.

"It's not a space-time wormhole, there's something wrong with your previous statement." Professor Zhou repeated: "It's not a space-time wormhole, it's a space-time wormhole. ”

"Assuming that the time of the two parallel worlds is synchronized, and you come to this world from the original world, and only a few days have passed, it means that this trip has not disturbed time, in essence, you have teleported from one place in the universe to another."

"You mean, Yan Xiuze's world and ours are actually in the same universe?" Bai Xuyan asked tentatively.

"It can be understood in this way......" Professor Zhou nodded: "In fact, this concept is not difficult to explain, assuming that the universe we live in is infinite, but the order of arrangement between microscopic particles is limited, then in the infinite universe, there will inevitably be two planets with exactly the same order of particles." ”

"And because the maximum speed of the universe is the speed of light, and the universe is constantly expanding, the distance between the two planets will quickly move away at a speed far exceeding the speed of light, so the people of the two planets will not be able to influence each other no matter what, so the two planets will naturally become parallel worlds that do not interfere with each other."

"So I guess that the so-called parallel world should be under the same big universe, far away from another corner...... It's just that this corner is likely to be hundreds of millions of light-years away, and with normal means, we can't reach it in a lifetime. ”

"And Yan Xiuze, who tore through the barrier of space by abnormal means, came to our world, I have to say that it is a miracle."

"But according to what you say, there are more than two parallel worlds that are exactly the same!" Bai Xuyan continued: "But there are countless worlds with the same permutations and combinations? ”

"It can be understood so, but it is based on the infinity of the entire universe." Professor Zhou pushed the spectacle bone on the bridge of his nose and said slowly: "Of course, the appearance of Yan Xiuze now proves a point of view: even if the universe is not infinite, it is beyond our imagination!" ”

"And if the 'antimatter explosion' that Yan Xiuze said can really give birth to a spatial wormhole, then it is not difficult to send him back to the original world."

"But it doesn't make much sense to say that now...... Without antimatter refining and storage technology, it would be impossible to reproduce the spectacle of the 'antimatter explosion', right? Yan Xiuze said dejectedly.

"This ...... Not necessarily. Professor Zhou said thoughtfully.

"Not necessarily?" Yan Xiuze raised his head suddenly, and hope was once again ignited in his heart.

"The antimatter explosion created a space wormhole, that's the conclusion you came to, but is this conclusion really correct? Or could this be just a façade on top of the real principle? ”

"Appearances? I don't understand......" Yan Xiuze's face showed a confused look.

Professor Zhou smiled and explained, "That's right, the wormhole appeared after the 'antimatter explosion', but we can easily understand that the wormhole was created due to the antimatter explosion...... But in reality, this may not be the case. ”

"I noticed your previous description, after the wormhole is created, there is a huge gravitational pull, right?"

"That's right, if it weren't for the strong suction of the wormhole, I wouldn't have been here." Yan Xiuze said helplessly.

"Then the question is, what exactly created that 'space wormhole'?" Professor Zhou asked rhetorically: "Is it a concentrated explosion of antimatter, or is it a 'gravitational distortion' caused by the explosion?" ”

"You mean that the main cause of inducing space wormholes is a change in gravity?" Bai Xuyan's eyes lit up and added.

"Based on the analysis of the information we know so far, this is the most likely statement." Professor Zhou nodded and said with a smile.

"Therefore, as long as the gravitational force of the local area can be changed to a limit, it may be possible to reproduce the ...... of the 'space wormhole' at that time."
