Now Xiao Yu's understanding of space technology is still very scattered, and he does not have a systematic and comprehensive understanding. Xiao Yu is still not very clear about the state in which this small universe exists.
"First of all, we can be sure that on a four-dimensional scale, the small universe we are in is not far away from our big universe." Xiao Yu said, "When we were still in the big universe, what we observed was
The phenomenon that the orbit of the star is unstable can illustrate this point."
"Yes, existing scientific and technological theories, as well as our observation results when we were avoiding the information storm in the semi-four-dimensional Taihao body, can prove that gravitons can be transmitted in the fourth dimension, and it also follows the rules of our three-dimensional world.
The law of physics is that the farther the distance, the smaller the gravity, and the closer the distance, the greater the gravity." Luca 3 said, "I speculate that there is probably some kind of force between our big universe and this small universe.
The link of connection, this link, is gravity. I think that this small universe may be pulled by the gravity of the large universe, and it is making circular motion around the large universe on the four-dimensional level."
"Is it circular motion at the fourth-dimensional level..." After hearing Luca No. 3 finish his opinion, Xiao Yu began to think silently.
"There is a loophole in this statement." A scientist from the Department of Science and Technology said, "Let's take a look."
The scientist issued a few instructions to his computer terminal, and a three-dimensional animated image appeared on the conference table.
In the image are two pieces of white paper, one large and one small.
"The big white paper is the big universe." The scientist pointed to the piece of paper and said, "The small piece of paper is the small universe we are in now. Now, the two-dimensional small universe we are in is orbiting the two-dimensional small universe.
The universe moves in a circular motion on a three-dimensional level."
As the scientist issued another command, 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 Three nodded slightly: "That's what I mean. In this system, gravity acts as a link, and the big universe pulls the small universe, making it impossible for the small universe to escape."
The scientist shook his head: "But in this system, there is a little contradiction. No, maybe it is not a contradiction, but a point that Mr. No. 3 has ignored."
"Oh?" Xiao Yu expressed his doubts in one word.
The scientist bowed to Xiao Yu and said: "As you can see, this two-dimensional small universe is making a three-dimensional circular motion around this two-dimensional large universe. But... I don't know if you have noticed this two-dimensional universe."
There is no motion trajectory of the small universe."
"Motion trajectory?" Xiao Yu was a little confused, but he reflected instantly: "I understand. Although this two-dimensional small universe is performing circular motion at the three-dimensional level. However, its trajectory is not exactly
At the three-dimensional level. It is moving simultaneously in two dimensions: length and width, and in the third dimension, height."
"Yes, this is what I want to explain." The scientist said, "The motion trajectory of the third dimension just adds one more dimension, and the two original dimensions it has are not lost. So what happens next?
, we can extend this question - since this two-dimensional small universe is still moving in the two dimensions of length and width in the three-dimensional circular motion, then...please take a look."
Unknowingly, the scientist's speech had attracted the attention of all scientists. Xiao Yu saw that in the conference room, scientists were constantly whispering 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: "One thing everyone needs to pay attention to is that this two-dimensional universe should not be so small. In fact, it should be very big.
"
It said and issued an order, so in the three-dimensional image, the larger piece of paper representing the universe began to expand rapidly, until it expanded to about three meters in radius, making the entire three-dimensional image smaller than the previous one.
Fully occupied.
Luca Three nodded slightly: "I understand."
"I understand too." Xiao Yu also nodded: "You are saying that the orbital radius of this small universe that revolves around the large universe cannot be larger than the radius of the large universe. Therefore, during the operation process
, it will inevitably intersect with the macrocosm, that is, it will pass through the macrocosm. Well... in one operation cycle, it will pass through the macrocosm twice."
"Yes, it's like this." The scientist said and gave the order, manipulating the piece of paper representing the small universe to continue to revolve around the big piece of paper. The small piece of paper performed a three-dimensional circular motion, Xiao Yu
See, this piece of paper slowly approaches the big universe, then passes through the big universe, leaves the big universe, reaches the apogee, starts the process of approaching again, and then passes through the big universe again, continues to move away, and reaches the apogee.
Then keep getting closer...
It goes round and round, never stopping.
"I speculate that the three-dimensional small universe we are in now also performs such a circular motion." The scientist said, "Our small universe moves in a total of four dimensions, length, width, height, and the fourth
dimension. It will also pass through the universe and have its own apogee."
"This is easy to understand." Xiao Yu said, "In fact, through calculation, we can completely know the distance between us and the big universe, which is the distance from the apogee. If calculated according to the orbit of the star, the small universe at the apogee
, it is about 14.3 billion kilometers away from the big universe. Well... according to the movement trajectory, at this moment we are probably less than 5 billion kilometers away from the big universe. But this distance is the fourth dimension.
How can we bridge this distance?"
Such a scene is like two two-dimensional worlds. Use two pieces of paper to represent the two two-dimensional worlds. The two pieces of paper are one centimeter apart, but this centimeter is a three-dimensional distance. People who live on this piece of paper
How can two-dimensional creatures span this three-dimensional distance of one centimeter?
This is a very vexing problem.
"We do not have the ability to move above the fourth dimension." A scientist shook his head and said: "I think that the method of directly crossing the fourth dimension and returning to our universe can rule out the legacy of the Trol civilization.
The information shows that space weapons are the key to leaving this small universe, and it is obvious that space weapons have little to do with the four-dimensional space. Our discussion must still revolve around space weapons."
"Yes." Another scientist agreed: "Not even the Taihao civilization has the ability to move in the fourth dimension, let alone us."
The discussion encountered difficulties at the beginning, and for a while, the atmosphere in the conference room was a bit dull.
"First of all, our method of escaping from the four-dimensional barrier set up by the Taihao civilization cannot be used here." Xiao Yu said slowly, "The environment is different, and the Klein bottle cannot connect two unrelated things.
In the three-dimensional world, it is not feasible to directly cross the fourth dimension. Senya, do you have any suggestions?"
This scientist who expressed his own opinions and brought a lot of inspiration to Xiao Yu and other scientists is named Senya. He is also a very outstanding scientist and has inspired Xiao Yu a lot in many aspects.
Senya pondered for a moment and slowly shook his head: "I don't have a specific and feasible way. I just think that since our small universe and the big universe will have an intersection, then we may be able to make some speculations based on this aspect. In the small universe
When we merge with the big universe, there may be some special phenomena that may help us leave this small universe..."
"Senya's opinion is very good, and the inference is basically reasonable. However, the rigor of a scientist prevents me from believing in any conclusion that is not supported by actual observational data. No matter how rigorous this speculation is, it is still just an inference, isn't it?
?My suggestion is to think of a way to either verify this inference or rule it out. Before we get a clear conclusion, all the work we do is just in vain and meaningless." Luca 3 shook his head
, expressed his own views.
When Luka Three spoke, Senya immediately stopped what he said, looked at Luka Three respectfully, and waited for Luka Three to speak.
Xiao Yu keenly noticed that there was a bit of gunpowder between the two. This phenomenon made Xiao Yu a little funny.
Senya and Luca 3 are both scientists in the natural science field of the Department of Science and Technology, but they belong to different civilizations, and Luca 3 is the undoubted authority in this direction. Senya's performance today can be said to be a steal.
It has taken away the limelight of Luca 3 and posed certain challenges to the majesty of Luca 3.
"How can it be so easy to secure the position of chief scientist of the Department of Science and Technology? Now that we occupy this position, we are destined to be constantly challenged by other outstanding talents." Xiao Yu thought to himself.
Regarding such healthy competition, Xiao Yu always holds an attitude of being happy to see the results, and lets them fight for themselves. Anyway, the final judgment is in his own hands.
"Senya's inference is very strict, but Luca No. 3's statement is not unreasonable. This inference really needs to be verified before taking the next step." Xiao Yu thought, and said: "Luca No. 3
That makes sense. So, do you have any ideas on how to verify this?" (To be continued...)
