At present, Xiao Yu's understanding of space technology is still very scattered, and there is no systematic and comprehensive understanding. What kind of state does this small universe exist, Xiao Yu still doesn't know very well.

"First of all, we can be sure that on a four-dimensional scale, this small universe we live in is not far from our big universe." Xiao Yu said, "When we are still in the universe, the phenomenon that the orbit of the star is not stable can illustrate this. ”

"Yes, the existing scientific and technological theories, as well as the observations we made when we were avoiding the information storm in the semi-four-dimensional Taihao, can prove that the graviton can be transmitted in the fourth dimension, and it also follows our three-dimensional physical law, that is, the farther the distance, the smaller the gravitational force, and the closer the distance, the greater the gravitational force." "I speculate that there is probably some kind of bond between our big universe and this small universe, and that bond is gravity. I think that this small universe may be pulled by the gravitational pull of the large universe, and on the four-dimensional level, it is moving in a circle around the large universe. ”

"Circular motion at the four-dimensional level......" Listening to Luca 3 finish his opinion, Xiao Yu thought silently.

"There's a loophole in that statement." A scientist from the Department of Science said, "Come and see. ”

The scientist gave several commands to his computer terminal, and a three-dimensional animated image appeared on the conference table.

In the image, there are two blank sheets of paper, one large and one small.

"Big white paper is a big universe." The scientist pointed to the piece of paper and said, "Small pieces of paper." It's the little universe we're in right now. Now, the small two-dimensional universe we live in is moving in a circular motion on the three-dimensional level around the two-dimensional universe. ”

With another command from the scientist, the small piece of paper began to move in the three-dimensional image, and it began to rotate around the large piece of paper representing the universe.

"Yes, that's it." Luca III nodded slightly: "That's what I mean. In this system, gravity acts as a bond, and the big universe pulls the small universe, so that the small universe cannot escape. ”

The scientist shook his head: "But in this system. There is a bit of a contradiction, no, maybe it's not a contradiction, but something that you overlooked, Lord Three. ”

"Oh?" Xiao Yu expressed his doubts in one word.

The scientist bowed to Xiao Yu and said, "As you can see." This small two-dimensional universe is moving in a three-dimensional circular motion around this large two-dimensional universe. But...... I don't know if you have noticed the trajectory of this two-dimensional small universe. ”

"Trajectory?" Xiao Yu was a little puzzled, but he reflected it instantly: "I understand." This two-dimensional universe moves in a circular motion at the three-dimensional level. But. Its orbit is not entirely three-dimensional. It is moving in two dimensions, length and width, and a third dimension, height, at the same time. ”

"Yes, that's what I'm trying to illustrate." "The trajectory of the third dimension. It's just that it has one more dimension, and the two dimensions it already has have have not been lost. Then we can lead to the question - since this two-dimensional universe is still moving in two dimensions, length and width, in a circular motion at the three-dimensional level, then ...... Everyone, please take a look. ”

Before you know it. The scientist's statement has already captured the attention of all scientists. Xiao Yu saw that in the conference room, there were constantly scientists talking to each other, talking in low voices, and talking about related matters.

The scientist pointed to the three-dimensional image on the conference table and continued: "There is one thing that everyone needs to pay attention to, that is, this two-dimensional universe should not be so small. In fact, it should be big. ”

As it spoke, it gave an order, and then, in the three-dimensional image, the piece of paper that represented the larger part of the universe began to expand rapidly, until it expanded to a radius of about three meters, occupying the size of the entire three-dimensional image.

Lukka III nodded slightly: "I understand." ”

"I get it, too." Xiao Yu also nodded: "You mean, this small universe that orbits around the big universe, its orbital radius can't be larger than the radius of the big universe, so in the process of operation, it will inevitably intersect with the big universe, that is, pass through the big universe." Kindness...... In one cycle, it passes through the universe twice. ”

"Yes, like that." The scientist spoke, giving the order, manipulating the piece of paper representing the small universe to continue to orbit around the large piece of paper. Xiao Yu saw that the piece of paper slowly approached the big universe, and then passed through the big universe, left the big universe, and after reaching the apogee, it started to approach the process again, and then passed through the big universe again, continued to move away, and continued to get closer after reaching the apogee......

Repeat the cycle, never stop.

"I speculate that the three-dimensional universe we are in now is also moving in such a circular motion." "Our small universe moves in four dimensions, length, width, height, and a fourth dimension," the scientist said. It also travels through the universe and also has its own apogee. ”

"That's understandable." Xiao Yu said, "In fact, through calculation, we can completely know the distance between us and the universe, that is, the distance of the apogee. According to the trajectory of that star, the small universe at apogee is about 14.3 billion kilometers away from the large universe. Kindness...... According to the trajectory of the movement, we are probably only less than 5 billion kilometers away from the universe at this moment. But this distance is the distance of the fourth dimension, how can we cross this distance? ”

Such a scene is like two two-dimensional shijies. Two pieces of paper represent two two-dimensional shijie, these two pieces of paper are one centimeter apart, but this centimeter is the distance of the three-dimensional scale, how can the two-dimensional creatures living on this paper cross the three-dimensional distance of this centimeter?

It's a big headache.

"We don't have the ability to move above the fourth dimension." One scientist shook his head and said, "I think that the method of directly crossing the fourth dimension and returning to our big universe can be ruled out. The message left by the Torol civilization shows that space weapons are the key to leaving this small universe, and it is clear that space weapons have little to do with four-dimensional space. Our discussion still revolves around space weapons. ”

"Yes." Another scientist agreed: "The ability to move on top of the four dimensions is something that even the Taihao civilization does not have, let alone us." ”

The discussion began with a difficult one, and for a moment the atmosphere in the room was a bit dreary.

"First of all, our method of escaping the four-dimensional barrier laid for us by the Taihao civilization cannot be used here." Xiao Yu said slowly, "The environment is different, and the Klein bottle can't connect two unrelated three-dimensional shijies. Nor is it feasible to directly cross the fourth dimension. Senya, do you have any suggestions? ”

This scientist who expressed his views and brought a lot of inspiration to Xiao Yu and other scientists is named Senya. He is also a very outstanding scientist who has inspired Xiao Yu a lot in many ways.

Senya pondered for a moment and slowly shook his head: "I don't have a concrete and feasible way. I just think that since our small universe and our larger universe will have a point of convergence, then we might be able to speculate on this aspect. When the small universe and the large universe converge, there may be some special phenomena, which may be of some help to us to leave this small universe......"

"Senya's opinion is good, and the inferences are basically reasonable. But the rigor of being a scientist makes it impossible for me to believe any assertion that is not supported by actual observational data. No matter how rigorous this speculation is, it's still just an inference, isn't it? My suggestion is to think of a way to either verify this inference or rule it out. Until a clear conclusion is reached, all the work we do is a loft in the sky, and there is no meaning. Luca III shook his head and gave his opinion.

When Luca 3 spoke, Senya immediately stopped his words, looked at Luca 3 respectfully, and waited for Luca 3 to speak.

Xiao Yu keenly discovered that a little smell of gunpowder arose between the two. This phenomenon made Xiao Yu a little funny.

Senya and Luca III are both scientists in the natural sciences of the science department, but they belong to different civilizations, and Luca III is the unquestioned authority in this direction. Senya's performance today can be said to have stolen the limelight of Luka No. 3 and posed a certain challenge to the majesty of Luka No. 3.

"If you want to sit firmly in the position of the chief scientist of the Department of Science, where is it so easy. Since he occupies this position, he is destined to be constantly challenged by the rest of the outstanding talents. Xiao Yu thought to himself.

For such healthy competition, Xiao Yu has always held an attitude of being happy to see it happen, and let them fight for it themselves, anyway, Zuihou's judgment is in his own hands.

Senya's reasoning is very tight, but Luca Three's claim is not unreasonable. This inference really needs to be verified before the next step can be taken. Xiao Yu thought about it, and said, "What Luca No. 3 said also makes sense. So, do you have a way on how to verify this? (To be continued......)
