Country L, Mount Lortes.
The majestic Lortes Mountains stretch for more than 300 kilometers from east to west, like an emerald-green dragon lying across the territory of the L country.
Country L is located on a beautiful island in the South Atlantic Ocean. It is located in the tropics, has a pleasant climate and beautiful scenery, and is a famous tourist resort.
At the same time, the country is also a country of immigrants. Since the prosperity of tourism, it has attracted immigrants of all colors from all over the world. Among them, yellow skin and white skin account for the vast majority of immigrants.
Although this place is located in the tropics, the main peak of Mount Lortes is covered with snow all year round, and the cliffs reach into the sky, like pillars of cloud standing proudly on the top of the seaside.
Looking up at the stars here, you can have a panoramic view of the vast sky. The sky is bright, the stars are dancing, and the beauty is endless...
The commanding height of the main peak, with an area of about 2,000 square meters, was leveled to the ground, and an astronomical radio telescope with a diameter of 80 meters stood among the green pines and cypresses.
The sky here is a bright mirror and the stars are dazzling. It is one of the best places on earth to observe the universe and stars.
Quan Entai is the main person in charge of this astronomical radio telescope base station. He has been working here since graduating from university and has been working there for 20 years.
Quan Entai is a second-generation immigrant. In fact, his original name was not Quan Entai, but John Brody. When he was 3 years old, a super typhoon hit country L. They were returning The family was swept into the sea.
At the critical moment, his parents threw him on the grass by the seaside, and he survived.
Later, a couple adopted him. His adoptive father was an astronomer. Under his influence, Quan Entai became obsessed with the vast starry sky.
In order to repay the couple's kindness in raising him, he took the initiative to take his adoptive father's surname. From then on, he had a new name - Quan Euntai.
He loves this job and will devote his whole life to the cause he loves.
In addition, he is also a well-known expert in the fields of astrophysics and communications in L country, and is also a member of the International Astronomical Society.
For three months in a row, he encountered a thorny problem, that is, the radio telescope captured a mysterious satellite every 15 days. In addition to receiving a strange delayed echo, it neither emitted electromagnetic signals nor Receiving electromagnetic signals, it is like a ghost that appears in the feed cabin of the radio telescope at regular times and at fixed points.
For this reason, Quan Entai mobilized all the staff in the base, but no information about this mysterious satellite was found for several weeks. They even checked the parameters and electromagnetic signal characteristics of satellites launched by all countries over the years, but still found nothing.
At this moment, in the hall that was as bright as day, they still did not give up. Everyone was working nervously...even if there were any clues about this mysterious satellite, no detail was missed.
"Look! Could it be this?" A staff member named Anders shouted, pointing at the computer screen.
Quan Euntai walked over quickly and looked at the screen with wide eyes.
This is an article published in Collier's Weekly by Nikola Tesla, the father of alternating current and a pioneer in electrical engineering, in 1901.
In the article, he detailed a strange radio signal he received during his current experiment. He wrote: Although this signal only lasted a few seconds, I could not understand its meaning, but I immediately realized that it was It may be sent by intelligent life beyond the earth. Maybe I am the first person to hear greetings from another planet.
Quan Entai shook his head. Although both radio signals lasted for a few seconds, there were no electromagnetic characteristics for reference and comparison. Nikola Tesla's description alone was not enough to prove that the two had the same emission source.
"Look! This weird delayed echo was also discovered in 1927!" said another staff member, Limiro.
said.
Quan Entai looked at the screen. It was a delayed echo discovered by a Norwegian radio amateur in 1927, which lasted only a few seconds.
A bitter smile appeared on Quan Entai's face. He was usually strict, but this time he did not reprimand the staff.
Indeed, this weird delayed echo, based on its electromagnetic signal characteristics, has ruled out satellites from all countries on the earth. Perhaps it was several weeks of non-stop work that allowed the staff to pin their hopes on the weird extraterrestrial. Civilization signal.
Quan Entai turned around and looked out the window. Under the clean and vast sky, the huge astronomical radio telescope was still working tirelessly... His thoughts drifted to the feed that appeared at a fixed time and at a fixed point every 15 days. Enter the mysterious ghost in the cabin.
"But, according to the information fed back by the feed module, it is indeed a satellite or a detector." Deputy Chief Engineer Li Xirong said as he walked to Quan Entai.
Quan Entai ignored Li Xirong. His eyes were still fixed on the radio telescope under the sky. It had accompanied him through countless nights in the past 20 years. He was confident of its reliability because it had never appeared before. No mistakes.
"Can you confirm now? The delayed echo we received is the same delayed echo received by Nikola Tesla and the Norwegian?" Li Xirong asked.
"There is a great similarity! Although it is not 100% certain, according to the tracking of the emission source, this delayed echo was emitted by the mysterious satellite." Quan Entai replied.
"However, it was only in October 1957 that mankind sent the first man-made earth satellite into the earth's orbit! Judging from the time, it definitely does not belong to any country or organization on the ground. So where did this mysterious satellite come from?" After Li Xirong finished speaking, his eyes Look at him.
The two looked at each other like this for about 10 seconds. His words suddenly woke up Quan Euntai! He picked up the mysterious satellite photo intercepted from the radio telescope and looked at it carefully...
This is a dense metal object, shaped like an eagle's beak, with a dark black appearance.
"Has the material analysis report of this object been released?" Quan Entai asked.
Li Xirong nodded and handed him a pile of analysis reports.
He read through it carefully: using an infrared spectrometer to conduct qualitative analysis of the compound, it has a dense structure; using an X-ray diffractometer to analyze it, it has a unique crystal structure.
At the same time, in quantitative analysis using an inductively coupled plasma spectrometer, it does not belong to any element known on Earth.
Conclusion: Quan Entai's team compared all the atomic structures currently known on the earth and found no matching element type.
"It is indeed an alien body!" Quan Entai murmured while flipping through the material analysis report.
The more he looked through the materials, the more solemn his face became. He realized that this would be a discovery that spanned the ages. The team he led was the first to observe and analyze this mysterious satellite at close range. What was waiting for them would be something with extraordinary capabilities. A landmark event.
But soon, he discovered that they were not the first to witness the mysterious satellite.
This is a set of eyewitness reports from 1954.
According to a newspaper report from that year, a Ph.D. in astrophysics from country M named Daken Lapas observed this mysterious satellite for the first time from an array telescope. He called it the Black Knight Satellite and paired it with Have clear photos.
Quan Euntai took the photos in the newspaper and compared them carefully, and couldn't help but gasp!
The photo of the mysterious satellite captured from the feed cabin of his radio telescope was exactly the same as the photo of the Black Knight satellite mentioned in the newspaper!
His face became extremely serious. It would be a little thin to judge that it came from outside the earth just through electromagnetic signals, but now, with this eyewitness photo from 1954 in front of him, it was real. The irrefutable evidence.
You must know that in 1954, humans had not launched any artificial satellites, which meant that this Black Knight must have come from outside the earth and was a space probe launched by a veritable extraterrestrial intelligent life.
"Can I contact the Black Knight?" Quan Euntai asked Li Xirong.
Li Xirong nodded, and immediately, the staff in the hall began to send electrical signals to the Black Knight. The wavelength and frequency of the electrical signals were exactly the same as the intercepted delayed echo.
10 minutes passed with no response from the Black Knight.
2 hours....
No response.
5 hours...
Still no response.
"Maybe the Black Knight is damaged?" Li Xirong said.
"Unlikely!" Quan Entai shook his head, "It has been more than 100 years. Except for receiving that weird delayed echo, Earth's technology is no longer comparable to that of that era. After so many years, we only recently intercepted it. It proves that it must have achieved remote orbit change."
Li Xirong nodded. Quan Euntai was right. If the Black Knight had not frequently appeared in the observation range of the radio telescope at regular intervals and at fixed points recently, they might not have been able to discover it.
Because, since it was first observed in 1954, it has disappeared. Even today, with the rapid development of science and technology, and the launch of hundreds of earth satellites, it has only mysteriously appeared recently.
"If it comes from distant space, it will definitely not use electromagnetic waves to send signals. It may be another communication method unknown to us!" Quan Euntai said.
"Could it be quantum communication? A communication method based on quantum entanglement across time and space?"
"Well...I can't rule out this possibility!"
"Aren't you going to attend the World Quantum Communication Conference next month? Liu Hanyang and René, two famous experts in the quantum field in the world today, will both participate. You can let them analyze it."
Quan Entai nodded, but his intuition told him that the Black Knight had appeared frequently recently and must have discovered something on the earth that particularly interested them.
Is it friendly? Or hostility?
His eyes turned to the screen, carefully examining the strange delayed echo from the Black Knight.
"Decipher this delayed echo!"
Soon, the electrical signal of the delayed echo was deciphered.
This is a star map of the constellation Boötes. Obviously, this is the spatial position information emitted by intelligent life.
There are 6 planets distributed around a binary star system on the star map. From the inside to the outside, there are 4 rocky planets and 2 gas giant planets. Among them, the third planet of the 4 rocky planets is specially marked. Obviously , this is the home of intelligent life.
Based on the position information of the star map in the universe, Quan Euntai quickly found out that this binary star system is the epsilon star of the Boötes constellation---Geng Heyi.
Terrestrial Star is a binary star system composed of a bright yellow giant star and a smaller main sequence star, located 210 light-years away from Earth.
The yellow giant star has exhausted its hydrogen and is at the end of its stellar evolution stage.
He fell into deep thought: 210 light years away! If the Black Knight were flying towards the Earth at the speed of light, it would have set sail 210 years ago!
If it flies at 50-90% of the speed of light, then it has been traveling in the universe for thousands of years!
This means that the Genhe civilization is several orders of magnitude ahead of the Earth's civilization. It can be said to be a crushing...
Quan Entai simply didn't dare to think about it any more.
An ominous premonition came to my mind...
