Space
Just as he had thought, the most likely explanation was that something was obscuring the view.
Keep in mind that the human fleet is currently in interstellar space, with nothing in nature to obstruct its view. Since it's not a natural phenomenon, it must be something created by some civilization.
But what exactly could be so massive?
Yes, it could also be the Starry Sky Behemoth I mentioned earlier. The idea of a behemoth is hard to accept, mainly because it's difficult to comprehend the concept of life wandering in space. However, the universe is vast and full of wonders, and many things that humans consider abnormal may not be abnormal to the universe.
Taking a deep breath, Yue Yuan immediately shouted, "Pass down the order: the entire fleet, enter Red Alert status, and the fleet formation, centered on the Residential Spaceship and other engineering ships, will change to a spherical formation!"
"Yes, Commander Yue!" the person in charge of relaying the order replied, and then inserted Yue Yuan's words into the fleet channel.
"Chief of Staff, what's going on?"
The sudden order puzzled several scientists in the Lyra Command Center who were detecting Gravitational Wave signals using Laser Interferometer Space Antenna array, because the Laser Interferometer Space Antenna array disappeared as soon as the fleet moved.
In response to the scientists' questions, Yue Yuan briefly explained his own conjecture.
Immediately, the atmosphere in the entire Lyra Command Center became heavy.
"Could this Commander Yue be a natural phenomenon?" The Lyra Science Officer asked hesitantly, seemingly unsure.
Yue Yuan shook his head. He still didn't believe it was a natural phenomenon, but it seemed the Science Officer had something to say, so he asked, "What's your opinion?"
"This situation is most likely caused by some colossal object, just as Commander Yue and Staff Officer Liu said, either by some civilization or some kind of Starry Sky Behemoth." The Science Officer first affirmed Yue Yuan's and the staff officer's speculation, and then began to Chen Shu his own opinion.
He turned to Yue Yuan, a thoughtful expression on his face, and said, "I think it's not impossible that it's a natural phenomenon. For example, our fleet may have passed through some peculiar space. The characteristics of this Peculiar Space make it impossible for us to observe the universe through any means of observation when we pass through it. This could also explain why the fleet did not appear synchronously."
"Peculiar Space? What Peculiar Space? Could it be the legendary Four-Dimensional Space?" Upon hearing the Science Officer's words, Staff Officer Liu immediately showed an incredulous expression. He exclaimed, "Are you saying that our entire fleet just passed through a Four-Dimensional Space? Or a naturally existing Four-Dimensional Space? And we didn't even notice it when we passed through it? That's impossible!"
Staff Officer Liu thought to himself that this Science Officer must have been reading too much science fiction.
"No, no, no, it's not Four-Dimensional Space. It's probably some kind of Peculiar Space, three-dimensional." The Science Officer denied the Four-Dimensional Space claim.
Then the Science Officer turned to look at Staff Officer Liu, seemingly reading his thoughts from his face, and continued to explain, "Although we don't know much about Four-Dimensional Space, we're not completely ignorant either. In our scientific theoretical system, there are still some descriptions of higher-dimensional space."
If our scientific theoretical system is not fundamentally flawed, then we cannot enter either the lower-dimensional Two-Dimensional Space or the higher-dimensional Four-Dimensional Space.
Because theory shows that the Coulomb Force in Two-Dimensional Space is inversely proportional to the first power of the distance, as a life form in Three-Dimensional Space, once we enter Two-Dimensional Space, regardless of other spatial properties, the Coulomb Force alone is enough to change the physical laws that sustain our bodies and all three-dimensional things.
Our bodies, and other three-dimensional objects, are compressed because the Coulomb Force, which was previously inversely proportional to the square of the distance, becomes inversely proportional to the first power, causing the structure to be disrupted at the level of physical laws.
At this point, the Science Officer shrugged, implying that since the laws of physics had changed, the person was definitely gone.
He then added, "The same applies to entering Four-Dimensional Space. The Coulomb Force in Four-Dimensional Space is inversely proportional to the cube of the distance. Any life or thing in Three-Dimensional Space that enters it will inevitably be disintegrated at the level of the law of the law due to the change in the physical laws. Therefore, the Peculiar Space I am talking about is neither a high-dimensional space nor a low-dimensional space, but a kind of Three-Dimensional Space that we have never known before."
The Science Officer's statement seemed to overturn the general public's understanding of higher and lower dimensions, so someone couldn't help but say, "Uh, does that mean the plots in those movies where a person can freely destroy the interior of a three-dimensional object after entering Four-Dimensional Space are just nonsense?"
"It's not exactly nonsense. Just think of the characters in the movie as being protected by some kind of super technology, which allows them to maintain their three-dimensional structure," the Science Officer said, glancing at the questioner.
He said he wasn't talking nonsense, but his words actually revealed his point of view.
Unless one masters a technology that can maintain its own spatial characteristics, entering either a higher-dimensional space or a lower-dimensional space will only lead to certain death.
Similarly, if a civilization living in Four-Dimensional Space could not directly attack Three-Dimensional Space being, they would not be able to directly attack it. From an optical perspective, they could indeed see the inside of a three-dimensional being, but to attack it, they would have to pull their own mental space onto the three-dimensional being's space. Only after the two spaces overlapped could the Four-Dimensional Space civilization possibly strike the inside of the Three-Dimensional Space being.
Instead of Four-Dimensional Space civilization directly leaving four dimensions to come to three dimensions, because they simply cannot come to Three-Dimensional Space; if they did, they would die from dimensional reduction.
Unless they possess some kind of technology to maintain their own spatial characteristics.
The same applies to three-dimensional to two-dimensional.
If we consider paper as Two-Dimensional Space, then the paper we see is not an independent Two-Dimensional Space, but a two-dimensional Two-Dimensional Space that exists in Three-Dimensional Space while still maintaining its Two-Dimensional Space characteristics.
If there are living beings on it, then those two-dimensional beings cannot stand up directly from the paper. The only way for them to "stand up" is to make the "paper" "stand up" as well. This is what is called spatial overlap.
Of course, mastering a technology that can maintain one's own spatial characteristics would also work.
Seeing that the two were veerging into the topic of Space Technology and spatial cognition, Yue Yuan quickly interrupted them, "Alright, now is not the time to discuss these things. The most important thing is to think about what to do!"
Yue Yuan shook his head. Every time, he would come up with a bunch of guesses and conjectures, but none of them could actually solve the problem.
