After the "Art Sea Shell" operation was completed, according to the order of the Crisis Planning Agency, the 3-square-centimeter piece of metal collected from the alien irregular body was divided into two parts. One part was sent to Country M, and the other part was sent to Country M. It was urgently sent to the Materials and Molecular Research Institute of a top university in country Z.
The Crisis Plan commissioned the institute to study the composition, process, properties, elements and other physical characteristics of its materials.
The institute has a very high level of expertise in polymer materials, inorganic non-metallic materials, metal materials, composite materials, etc. The body skins and new coatings of a batch of recently installed advanced fighter aircraft are produced by the institute.
Liang Ruigang, a Ph.D. in Materials Science, is the main person in charge of the institute.
Fifteen days later, the research made a major discovery. At the invitation of Lieutenant General Li Jianfeng, Liu Hanyang and Li Mosen rushed to the research institute to jointly research and summarize the material.
Stepping into the university campus, you will be greeted by the dense tree shades, quiet corridors, and the smell of fragrant grass and earth, which is intoxicating and refreshing.
The volleying football, the bouncing basketball, the flipping books, the jumping pen tip, the vigorous posture and the concentrated thinking complement each other, the sunshine is bright, and the knowledge is erudite.
This was the first time he had entered the university since the arrival of the alien irregularity.
All this brought back endless memories for Liu Hanyang...
Once upon a time, he was also the young man who stood in the shade of the trees and in the pavilion, holding a book and meditating hard; once upon a time, he was also the athlete on the playground and in the gymnasium who fought against each other and ran forward and backward; once, he was even more so in the dormitory. , in the classroom, there are pillars of people laughing and bickering and writing fast.
The past has quietly left with the passage of time, leaving like a white horse passing by. For a moment, only small fragments like shadows are hidden deep in my heart.
Suddenly, a deep sadness poured into his heart. Faced with the mysterious alien irregular body, their almost crushing technology, the dilemma of the moon accelerating away, and the coming earth. Moon disaster, how long can this kind of beauty and happiness last?
Two years!
All this may become what it once was.
He calmed down. Right now, there are still many things to do!
Earthlings, never give up!
Liu Hanyang and Li Mosen entered the research institute, and a thin man in his 40s with black-rimmed glasses walked towards them. He extended his broad hand to them.
"I'm Liang Ruigang, welcome you two!"
"Lemmerson Academy of Sciences."
"Liu Hanyang from the Institute of Quantum Research."
After the greetings, Liang Ruigang led the two of them to a large pile of instruments. The 3 cm square piece of silver-white metal lay quietly under the atomic force microscope.
In order to obtain it, the member states of the Crisis Plan paid a heavy price, including the destruction of several naval ships by alien irregularities and the sacrifice of nearly 10,000 naval officers and soldiers.
"We used an infrared spectrometer to conduct a qualitative analysis of the object. It has a dense structure. Under the atomic force microscope, its atomic structure is very strange." Liang Ruigang pointed at the silver-white metal block and said, his eyes filled with wonder.
"Is it a known metal on earth?" Li Mosen frowned.
Liang Ruigang shook his head. After a moment, he said: "We used an X-ray diffractometer to analyze it. It has a certain similarity with the structure of titanium metal, but the structure inside is hollow!"
"Hollow?"
"Yes! It has the same atomic relative mass as titanium metal, but the arrangement is different. It is divided into two parts. The surface layer is a very thin film layer with a similar structure to titanium metal, and the inside is a layer that seems to have nothing. of hollow.”
Liang Ruigang said, turning on the visible spectrophotometer. On the display screen of the instrument, a circle of red light tightly wrapped a black area.
"The red light on the periphery is that layer of film." Liang Ruigang pointed to the instrument and continued, "This wrapped black area cannot be penetrated by light. At present, it is not clear what substance it is?"
"How thick is the film?" Liu Hanyang asked.
"0.05 nanometers."
"What proportion of the volume is occupied by the hollow space?"
"About 97.973%"
Liu Hanyang raised his head and looked into the distance. After a while, he looked back: "Did you use an inductively coupled plasma spectrometer to measure this hollow?"
"After measuring it, plasma can't penetrate it!" Liang Ruigang looked gloomy.
The room fell into silence. The three of them had serious expressions, but their minds were thinking hard about what kind of material this hollow was...
"Could it be antimatter?" Professor Li Mosen broke the silence.
Liang Ruigang shook his head: "If it is antimatter, it will annihilate a huge amount of energy with the surface metal film. We will get nothing except light and thermal radiation."
"In other words, if it were antimatter, this piece of metal would not appear here."
"Yes." Liang Ruigang nodded.
"What if it's dark matter?" Liu Hanyang's pupils narrowed and he said seriously.
Liang Ruigang's mouth was rounded, his eyelids were rolled up, his black eyes were wide open, and a surprised expression flashed across his face...
Suddenly, he seemed to understand something.
He started the robotic arm and moved the metal block to an X-ray diffractometer. A beam of blue light shot out of the laser head and then hit the metal block.
His eyes moved to the display screen. In the hollow part of the metal block, a temperature distribution map appeared.
Liang Ruigang's face immediately showed a look of surprise: "X-rays disturbed its magnetic field, and the fluctuations in the magnetic field caused temperature fluctuations in a short period of time. The different temperature distributions in the hollow part show that it has mass."
"Then..." Liu Hanyang's face showed extreme excitement and joy, "Then, there is only one possibility!"
"It is dark matter!" Liu Hanyang and Liang Ruigang said at the same time.
Liang Ruigang faced Li Mosen and nodded vigorously to him, his excitement palpable.
"Congratulations to both of you for discovering the legendary dark matter. You have made history and solved the material composition of the alien irregular body." Li Mosen said happily.
“According to the cosmic microwave background radiation and the standard cosmological model, many astrophysicists firmly believe that the matter that makes up our universe is composed of 15% visible matter and 85% dark matter. Unexpectedly, we have actually verified it today. existence." Liu Hanyang said with emotion.
"Now it is certain that the alien irregular body is composed of dark matter! This explains why our electromagnetic detector could not detect it before." Li Mosen said.
Liu Hanyang nodded: "Yes, because dark matter does not participate in electromagnetic interactions. Previously, the reason why we were able to observe alien irregularities was entirely because of the metal film on its surface."
"What do you mean?" Li Mosen had a surprised expression on his face.
Liu Hanyang looked at him with a stern expression. After a moment, his eyes turned to the piece of metal: "When the alien irregular body came to the earth, it was likely that there was no such metal film layer. No one knows how long it took for it to arrive? The fact that we detected it later depended entirely on their wishes.”
"You mean, they want us to observe it!"
"Yes." Liu Hanyang nodded, looked away from the metal block, and then continued, "Our opponent is a god-level civilization that exceeds our cognitive level. Maybe they are warning us? Maybe they are warning us? , they have nothing to do with the moon moving away.”
Li Mosen looked solemn and nodded: "With their level of civilization, we Earthlings are just a bunch of ants. If they want to defeat us, it will be easy. But until now, they have not taken the initiative to attack us."
After a while, he said thoughtfully: "Maybe they are hinting at something to us?"
The house fell into silence again...
About three minutes later, Liang Ruigang broke the silence: "But this doesn't mean that they won't attack us in the future. We still haven't figured out why the moon is moving away. Maybe they are waiting for an opportunity!"
Liu Hanyang and Li Mosen nodded.
After a moment, Liang Ruigang faced the window, his eyes slightly focused: "We seem to have a chance against them."
His words made Liu Hanyang and Li Mosen look surprised. They stared at him closely, their eyes fiery and doubtful...
"follow me!"
The two followed Liang Ruigang to a closed hall on the second floor, which is the weapons materials research and development center within the institute.
From a distance, Liu Hanyang saw Lieutenant General Li Jianfeng standing in front of a huge tempered glass. About 50 meters away from the glass, there was a goat wearing silver armor.
The three of them came to Li Jianfeng. After a brief greeting, Liu Hanyang and Li Mosen stared at the goat.
"The team led by Dr. Liang Ruigang successfully developed this protective device using reverse engineering in just 15 days." Li Jianfeng pointed to the silver-white armor on the goat and continued, " Its thickness is only 1% of A4 paper and its weight is less than 100 milligrams, but its protective power is..."
Li Jianfeng said, picking up a pistol from the table next to him, and with a "bang!" sound, a bullet hit the goat. Broken shrapnel splashed from the goat's body, and the shrapnel was instantly smashed into pieces by the huge kinetic energy. powder.
Surprisingly, the moment the bullet hit the goat, except for the slight shock to the armor on its body, the goat did not move at all!
"Our team reverse-engineered the film material of the metal block, changed its molecular structure based on titanium metal, and set it as an anti-energetic material based on the characteristics of the metal block. The protective power it showed far exceeded our expectations." Liang Ruigang said happily.
"If our fighter jets or ships use this material, then we will have the ability to withstand strikes against that alien irregular body. At least, we will not be reduced to the situation of wielding a stick to beat tanks." Li Jianfeng pointed out. He said while looking at the shining silver armor.
"What if a certain amount of dark matter is filled into the armor?" Liu Hanyang said with a determined look on his face.
Liu Hanyang's words seemed to wake up Liang Ruigang. A trace of surprise flashed across his face, and he raised a finger: "Everyone, wait for me for 10 hours!"
After saying that, he turned around and ran away...
