"The parallel universe can also be said to be a coaxial parallel universe, and the parallel universe, like the coaxial universe, is on the same time axis. So why do we make a distinction between them? Let me start with an analogy, the coaxial universe is like a big family, from one ancestor slowly evolved into a huge race, and all the people in the group are homologous. The parallel universe, on the other hand, is another family. ”

"Because the speed of light is finite and the Big Bang had a time start, there is a limit to the observed universe, and the corresponding boundary is called the cosmic horizon. The horizon refers to the maximum range of cosmic electromagnetic waves that can be received on Earth. Beyond this range, the light does not reach the Earth, so it can never be observed. Therefore, the cosmic horizon determines the scope of observation of the universe. ”

"Our universe only has a time history of about 13.7 billion years, so the most observable universe for human beings is probably centered on the earth, and then a circle is formed with a radius of 13.7 billion years, and this circle is all the universe that human beings can see at present. But our universe has been expanding since the Big Bang, and all the nebulae in the universe are moving away from each other, and they are getting farther and faster, so in fact, the limit of the universe that we can observe is 45 billion light years. ”

"The limit of 45 billion light-years limits the scope of our exploration of the universe, and we will never be able to explore the universe beyond that. For example, if two ants are on opposite sides of a balloon, and one of them wants to know if there is a similar kind on the other side, so he tries to crawl, and we can think of the crawling speed of the ants as the speed of light. But unfortunately, the balloon began to be blown up, and now we assume that the balloon will never burst, and the balloon's inflation rate represents the cosmic expansion rate, then the ants will never be able to find their kind on the other side, or even farther and farther away. For example, if you are on a highway and you find that the car that was still in front of you suddenly disappears, and you can't catch up no matter how fast you do, it is not because the car in front of you is faster than you, but because the road under your feet is constantly lengthening. ”

Therefore, the coaxial universe that we have been talking about is limited to our current cosmic horizon. So for the possible civilizations outside of our cosmic horizon, the cosmic horizon in which they are located is what I call the parallel universe, and we and them are like two big families that can never intersect. ”

"Because the universe is expanding, our cosmic horizon is also constantly changing, and we can observe more and more areas, but we can observe less and less matter. In hundreds of millions of years, galaxies that were originally within our observation range will move away from our cosmic horizon. If there were civilizations in that galaxy as well, then we would never be able to intersect from being connected to never being connected. And that civilization will go from our coaxial universe to a parallel universe. ”

"The whole universe is composed of countless such parallel universes that are independent of each other, and the universe that we call parallel universes must have civilizations, while the inanimate universe is called the blank universe, and they occupy the vast majority. However, our research is meaningless, so I will not elaborate on it. ”

"Since the universe expands faster than the speed of light, no matter how close a parallel universe is to the edge of the universe, it is only relatively close. In the universe, beyond the limit distance that light can reach, and between it and the absolute boundary of the universe, there will be a huge space without light, which I call a polar barrier. There is no light, no matter, no information transmission in the polar barrier space, it is a forbidden area for thinking life, even immaterial life cannot be touched, it is an absolute blank. The only thing that can prove the existence of a polar obstacle is space and time, and nothing else. ”

"Therefore, as three-dimensional beings living in the four-dimensional world, it is impossible for us to leave this universe and walk out of the boundary, because we cannot be faster than the speed of light, and theoretically it is impossible to even see extreme obstacles. But this false world must be ended, and if we want to continue civilization, we must get out of here. However, the rules of this universe limit that we can never leave, and at this time, no matter what we do, what should we do?" Bai Didi threw out a question, and then quickly gave a conclusion, "Reincarnation Channel!"

"As we all know, the reincarnation channel is an extreme product that can go directly to the universe under high-dimensional interference, ignoring all the physical principles of the universe such as time and space, and relying on high-dimensional energy. Its generation is an accident, and we cannot perceive the existence and activities of high-dimensional beings, so we naturally cannot know the operating principle and cause of the reincarnation channel. But it undoubtedly paved a highway for us out of the ravines. ”

At this time, Dr. Mi stood up again, raised his right hand high, and was seen by Bai Didi and nodded before he began to ask, "Professor Bai, do you have any guesses about the cause of the reincarnation channel?"

"Didn't this Doctor Mi be notified by the radio that he went to a closed room because of some abnormality? Bai Dian said on the side.

"Why are you a ghost in charge of so many things? Su Mancheng responded.

"Alas, it's boring, when are we leaving?"

"It's not okay, right? I guess you want us to listen to this?" Ye Qingmian was also a little tired, not physically, but mentally, the liberal arts student said that he really couldn't listen to it, and he talked so much for a long time, which did make everyone have some new views on this universe and become clearer, but! But Ye Qingmian didn't want to know how the reincarnation channel came about, he wanted to know more about real things, such as how to get more powerful Bible power, such as how to successfully pass the reincarnation selection.

According to Ye Qingmian's thoughts, it is best for each person to send some reference books such as "Five-year Preliminary Selection and Three-year Second Selection", "QD Reincarnation Game Skills", "Detailed Explanation of Huanggang Ability", and the sea of questions is king. This kind of empty slogan is like the principal's nonsense at the teacher-student conference, no matter how much he says, no matter how much he understands, what is the use?

Yes, but again, given that we can't make observations of higher-dimensional existences, it's just conjectures. Bai Didi said, "There are several more reliable conjectures now, the first is also the more mainstream conjecture, the Colosseum conjecture, that is, our universe, for high-dimensional life, is like a cage, we are the tools waiting in the arena to have fun, and the arena is the reincarnation game, and the winner can be free through the reincarnation channel." The second, the alternate civilization conjecture..."

"I'm sorry Professor Bai, can you interrupt?" said Mi Yukong with a polite bow.

"You say. Bai Didi didn't care, but politely asked Mi Yukong to express his opinion.

"What you said is widely known, can I take the liberty of asking you about your personal understanding of the reincarnation channel?"

"Hmm... There is absolutely no basis for my thoughts, and sometimes even I wonder if it is ridiculous, and since you asked, I might as well say it, and everyone can listen to it. Bai Didi said with a smile, "I once guessed that the initial establishment of the reincarnation channel may not have been prepared for us at all, to be exact, not for the indigenous civilizations in any universe. ”

"Since the rules are set up to unlock a lot, just so that we can't reach the boundary of the universe. So why open a back door? I once thought that the reincarnation channel might have been built for itself by some high-dimensional being. I have said before that there is a possibility of evolution and degradation of life in different dimensions. Is it possible, then, that it was an injured high-dimensional life that set up a passage for itself to escape when it was unable to maintain its original dimensional existence form. This means that when it is forced to descend to our universe, it can recover itself and leave here quickly through the shortcut of the reincarnation channel. ”

"Professor Bai, do you mean to say that it's like a person who offends someone, in order to avoid being chased and killed, he will hide in prison, and the limelight will come out, is this probably the case?"

"Well, it's not too appropriate, but it's not wrong either. At least that's what I thought. ”

"Is the reincarnation channel prepared for the high-dimensional beings themselves? Ye Qingmian muttered to himself.

"I see, that..." Mi Yukong was about to continue to ask questions, but the door was suddenly knocked open, and two middle-aged men broke in with anxious faces, looking around rudely and shouting at Mi Yukong.

"What are you doing?" Mi looked at the two reckless men angrily.

"I'm sorry Director Mi, I'm sorry Professor Bai, the matter is urgent, and we have no choice but to do it, I'm really sorry. The two men apologized as they quickly walked over to Miku.

"What's going on?" Bai Didi asked.

"An hour ago, Subject TZ199-A1905 was monitoring anomalies. A few minutes ago, A1905's vital signs were very erratic and could have died at any moment. One of the middle-aged men quickly explained to Bai Didi, and at the same time pulled Mi Yukong, "Director Mi, let's go, it's too late to hurry up, A1905 can't die now!"

"You go get busy, the things in the lab are more important. Bai Didi said to Mi Yukong.

"Okay!" Mi Yukong also knew that the matter was urgent, and he had received the previous notice, but it was too common for the test subject to monitor abnormalities, and he didn't expect it to become so serious in such a short time, and he was also a little lied for a while.

But Ye Qingmian and the other four were a little embarrassed, "Shall we follow?"

"This 'lesson' here isn't over yet, right?" Su Mancheng was a little entangled, not knowing what to do.

"Let's go out and have a look, and if the route Doctor left is consistent with our road map, then follow the past, and if not, we'll come back. After Zhong Ming made a decisive decision, several people also followed Dr. Mi and left quickly.

But when a few people were about to come out through the wall, the words below the white drops made them stop.
