Everyone's novel welcomes you, please remember the address of this site :, mobile phone reading, so that you can read the latest chapter of the novel "Galaxy spokesperson" at any time ...
In the Thunder Temple of Langtu Mountain, in front of the screen wall, a large wooden barrel is filled with cheese, and a large barrel of hot water is filled with various Chinese medicines, including Xiang mushroom powder. As for the cheese itself, the whole body is soaked, only the head is exposed.
Nobita comforted him strongly and said, "Relax, small cheese, you will be fine, trust me!"
Cheese said with a bleak smile: "Boss, I believe you."
But I heard that the robot from the gluttonous universe Fengshen in the Sixth World continued to introduce: "The set of cards you see is not the true face of the universe, but only a two-dimensional description of each universe. Because we will talk about it later. To the four-dimensional universe. I would like to ask you to describe to me what is the four-dimensional universe, who can? "
Everyone shook their heads, Zhou Jinyin said: "We are people living in a three-dimensional universe, we are all three-dimensional, including the robot you, all the objects here are three-dimensional, including our thoughts, so for what you said Of the four dimensions, we simply cannot describe it, nor can we imagine it. "
"So the dimensionality reduction description is used. The dimensionality reduction here is not a real dimensionality reduction, but a method of description." The robot continued, "Now back to the cards again, the cards you saw Each card represents a universe, and the cylinder formed by these cards is the upper level of the four-dimensional universe. As for the specificity of the four-dimensional universe, we do n’t know what we can do, we can only rely on imagination. There are five dimensions, six dimensions, and even higher unimaginable dimensions.
"In this cylindrical card, our ancestors discovered a huge secret, that is, there are four unrelated cards, and there is a connection between the cards that are far away. After years of research, we have found In this connection, it is that these four cards form a peculiar formation, which is the teleportation formation.
"As long as a portal is established in each universe, you can move freely in these four universes."
Nobita raised his hand and said, "Mr. Robot, I want to ask you a question."
"Please say."
"As you say, the portals distributed in these four universes are the gates between the universes? How was the portal built in the beginning? Because I know of any two of the four universes The distance is so far beyond imagination that you ca n’t reach any party before there is no portal. Am I right? "
"You are absolutely right. The distance between any two universes is so large that you use the speed of light, even if the universe is destroyed, you can't reach each other." The robot said, putting a card in the barrel Pull it out and put it aside, and a little more, that card turned into a ball, and it pulled out a lot of cards, turning them into one after another. , These spheres are the true shape of each universe, and each sphere is a universe ... "
"Bubble Universe!" Nobita blurted out, because he once made a conjecture about the bubble universe like the consul.
"Bubble universe?" The robot asked, "It's a very good name, but it's more complicated than the bubble universe you mentioned, because it involves a four-dimensional universe. The universe in each ball is not simply a In a single super-universe, but in a four-dimensional universe. To be specific, it is very complicated, as long as you know that these represent each individual universe.
"According to what you people on earth say, each sphere has a diameter of trillions of light years. Isn't that number dare to imagine? And every two neighboring universes have reached hundreds of millions in diameter. Times the distance. Moreover, they are not necessarily in the same three-dimensional universe. "
According to robots, the diameter of one universe is one trillion light years, and the distance between two adjacent universes is one trillion light years! How vast the universe is, unimaginable!
"This is the real universe," the robot said, putting all of these bubble universes back into the card cylinder, and continued, "So our civilization designed this to allow people to understand this multidimensional multiverse universe view. Card theory is just for people to understand.
"So can you understand everything I said?"
Everyone nodded ignorantly, and Nobita said: "I can understand, but I still have a hard time understanding how you traversed the universe before building the portal."
The robot said: "According to this cosmological theory, it is indeed impossible to traverse before there is no teleportation. The distance of several trillion light-years cannot be traversed at all! So after our ancestors proposed the teleportation theory, it was also I have n’t been able to imagine this problem for a long time. But since there is the theory of teleportation array, although people realize that the theory of teleportation array is almost impossible to realize, it can be said that there is no need to build it ~ EbookFREE.me ~ Since there is this theory , There are still some people to try, so after many years of silence, finally the first portal was artificially created. There are twelve cosmic runes on this portal. In the process of continuous improvement of the theory of teleport array , The four universe teleportation arrays gradually rose to 12 universes. That ’s why you see 12 portals on the portal, including the universe on the base. "
"However, we saw three portals, not just 12 runes." Nobita asked questions again.
"Because there are dozens of hundreds of portals in each universe, and each gate has a rune, so there are actually more than 400 runes, that is, there are more than 400 doors." The robot answered.
Nobita asked again: "But why are the runes of World Six, which is your gluttonous universe, all the same?"
"It's not the same, it's a bit different, but it's just not marked out deliberately," the robot replied. "You see they are the same. That's because in our world, all portals are all concentrated in one place. Engineers are so involved only for the sake of mischief. "
Hearing the robot here, Daxiong said: "According to what you mean, there are only 12 universes to be transmitted? So, there is a way for us to go home on each door? It's just that when we go back, we are not in one place. ? "
"You are half right," the robot said. "There are indeed runes on every door that you can go home, but not 12 universes, but only four universes."
"Did you just say 12?"
"It's 12, but eight of them have never been online. They haven't been online since the beginning."
"What do you mean? I didn't understand." Nobita asked with doubt.
