[50 Years of Crisis, Scout Team]

In order to verify the accuracy of the news of the destruction of the "pseudo-civilization", the federal government decided to send a reconnaissance team to the neutrino signal emitting source. As a result, the Solar System Federation Fleet dispatched 15 of the fastest and best-performing antimatter ships on board, led by Colonel Durand, with team members ranging in rank from sergeant to sergeant. In addition, there are two people who are not soldiers, and that is the first witness of the news: Wang Jiangbo and Ye Wei.

When the reconnaissance spacecraft launched, the fleet was hovering in the orbit of Jupiter, and the neutrino emitter was about an astronomical unit within the orbit of Pluto. Since the antimatter spacecraft can reach a top speed of 60% of the speed of light, the reconnaissance fleet will only need five days to arrive, perhaps less. That's a very fast speed.

Fifteen stars loomed in the deep night sky, and Captain Dongyang Qiyue looked at those stars deeply. She knew they were on their way.

Six days later, the reconnaissance team had reached the target location. Six days – one more day than the actual flight time, as they had an extra day to slow down.

As soon as I arrived at the signal source, I found that there was nothing there, it was still deep in space, dark and mysterious.

Wait, nothing? It seems strange. However, the true two-dimensional plane is not visible to man, it is the side without thickness, and light can pass directly through it, like a projection of the cornerstone empire. It's not theoretically okay to see it. It is this that leads to the "invisible" effect seen by the reconnaissance team. But if so, then there is a doubt? If there really isn't anything, then the picture in the photo in the message can't be explained.

In fact, the sender of the message only sees a two-dimensional energy release effect, which cannot be maintained for a long time. At the time, Peng Xiaoming only wrote down the effect of energy release in photographs (the form of energy radiation happened to be visible light). By the time the scout arrived, the energy release effect had ended, so nothing could be seen.

After several hours of probing, it wasn't like they didn't find anything: they found a fragment of an enemy warship somewhere, and it was lucky that it didn't completely fall to the lower dimensions due to a dimensional strike, because half of it was in the fall zone and half was outside, and the probability of such an event was negligible.

The shard was strange, as if it had been cut off by something. This is not the strangest thing, the strangest thing is that the cut section is so flat and intact that it is the same as the cross-sectional structure that was not cut. Even laser cutting can't be so flat!

"Colonel Duran, don't you think the structure of this fragment is very strange?" Ye Wei said.

"I think. See. Durand looked at the captured fragment carefully.

"Don't you think we're a bit like archaeologists?" Wang Jiangbo asked with a smile.

Ye Wei smiled: "You are very humorous. ”

"This piece of shard, let's assume it shattered when the hull was attacked. But if it is fragmented, its section will be somewhat uneven. Its internal structure, or section, is neat. "So, what kind of blow can destroy a battleship without destroying its internal structure?" ”

Wang Jiangbo turned on his watch and called up the picture he received on the space station. He had downloaded the image on his phone long ago.

"Look! This is the image that the neutrino signal is transmitting. Wang Jiangbo pointed to the information window to everyone. The image captures a plane next to pitch black space, on which is a battleship with a long-broken structure, and the fusion reactor inside is still sending light in two-dimensional space. The scene of Wang Jiangbo's spaceship was synchronized to the other fourteen ships, as did the other ships.

"But there's nothing here? Are you sure this is here? The officer on the other ship said through the communication channel.

"Sure. This is the picture sent by the sender of the message. But...... There's really nothing here. Durand said.

"Eh, you say, is the plane on this photo just a image, just a light image, and the real thing is no longer here." In the many live broadcast screens, the scientific officer of a spaceship said.

"However, this way of destroying and striking is indeed a bit bullish." Ye Wei sighed.

"Really smack!" Wang Jiangbo echoed.

"Could it be that the battleship in the picture is on a flat surface, then the attacker may have lassoed it with a weapon that resembles a plane, which may resemble a weapon with a hypothetical energy wall lasso." Duland's scarf said.

After that, there was silence. In the incomparably dark sky, the silence seemed even more silent.

"I see!" Suddenly, a man broke the silence of the mystery, like a strong wind blowing the surface of a calm lake. Or the scientific officer: "The reason we can't see it is because it's two-dimensional – it's a plane, an infinitely thin plane." And the reason why the battleship is crushed on the 'painting' is that it is compressed into a 'painting'. Its original internal structure was destroyed. ”

“？” Everyone was in disbelief, only the voice of the scientific officer still echoed and reverberated for a long time......

"You know what else came to mind?! I thought of the mass-energy equation, the disappearance of those objects – that is, the disappearance of mass...... And mass can be converted into energy, and those objects are converted into light radiant energy! Since it becomes two-dimensional, their mass is no longer meaningful to three-dimensional, so they are all turned into energy and emitted. That's why you can see it, and it's not what you can see, it's just its energy release effect! But the two-dimensional image it becomes is real. The scientific officer said excitedly. At this time, all the members of the reconnaissance team were glad to have brought a scientist with them.

Speaking of which, Durand took over: "So, their weapon is to make objects ...... No, no, no, it's the whole space, all huddled in one dimension into the microcosm, forcing one of the dimensions to only be owned by the microcosm, so that the macroscopic dimension is lowered! If I had to give this particular strike a name, I'd call it 'Dimensionality Reduction Strike'."

The scientific officer nodded, applauded, and said, "String theory...... Unexpected! Colonel Duran, you are not an amateur in physics. ”

When everyone was in the clouds, only two people really got the answer.

"I've got to think about it." With that, the scientific officer returned to the cabin, where he opened several draft windows with his watch and mobile phone, and did the math inside......

After a few hours of rest, some people who didn't understand gradually understood, and the scientific officer came to the final result.

The scientific officer cleared his throat and spoke loudly: "Indeed. As originally envisaged. The weapon should be a space, the same as ours, nothing-having space, with the only difference: it is two-dimensional, and its dimension is two. Three-dimensional space or objects, when touching that space, will be reduced in dimension due to the limitation of the low dimension of that space. There is a rule in the macro dimension: when a high-dimensional space comes into contact with a low-dimensional space, it will fall to the lower dimension, like a waterfall flowing down a cliff, and suddenly it seems to become 'flat'. And the lost dimension did not disappear, it became one of the seven dimensions in the microcosm, until the fall was complete, and only two dimensions of that space would have macroscopic structures, and the other eight dimensions would only be in the microcosm. ”

"So to speak. Explained perfectly. Wang Jiangbo said in awe, "In fact, the dimension itself is the structure of space and objects." ”

"It can be understood that way, but what it really means is a vector of space." Durand said.

Wang Jiangbo thought for a while and said: "Do you say that there is a possibility that the original ten dimensions of the universe have been extended to the macrocosm, but our current universe is three-dimensional, which is caused by the abuse of this dimensional weapon by the intelligent civilization of the previous dimension. ”

This sentence made the scientific officer think for a moment, and it seemed to touch a nerve in his mind: "If the real world is like this, then how powerful should those civilizations of the previous universe be." How terrible the battle of the ancients will be! If that's the case, I hope that the current three-dimensional universe will not be low-dimensional. ”

"Hehehe, aren't you talking about "The Three-Body Problem"?" A soldier said.

"What is the 'three-body problem'? Is it an object? ”

"It's an ancient science fiction novel, written by a guy named Liu Cixin. The internal vision is the same as what you just had. It is also famous in ancient times, such as Baoshu's "Ruins of Time", Han Song's "Cosmic Tombstone", and Jiang Bo's "Red Stone". ”

"Haha, 'Ebo'?" Wang Jiangbo said, "It's like my name!" ”

"Hey, guys, it's been such a rewarding journey that I have to celebrate. Let's go, go and see Pluto. Durand said.

"Let's go and play with the god of the underworld." Wang Jiangbo said with a smile.

"Hahahaha!" It drew a burst of laughter from the crowd.
