: 830 Extraterrestrial Civilizations!

"The second one, it looks fast." Holding both hands on the back of his head, Guan Ming walked on his way home alone.
No one was around, and Guan Ming didn't have to disguise his custom-made electronic glasses.
"No way, the previous chairman was caught and there was a leak about the new missile defense system being developed. Even the military was disappointed with the chairman, and even more angry at Raytheon. They are expected to rank in the Global 500 this year. Well, but there should be no hope now. "Shuangxing replied with a chuckle.
"What good idea do you have for this second chairman?" Guan Ming didn't care about the so-called missile defense system. As long as there were two stars, everything was under the control of the two stars unless it was back to 100 years ago.
"Not yet, but the chairman has insufficient personal ethics. There are many scandals. I have investigated and there are many real hammers."
With Guan Ming's will as the highest guidance, the Double Star assisted from the side, and extended more to the U.S. arms dealers. After all, the Republican Party represents the interests of arms dealers. As long as it extends to the arms dealers, it wants to kill a few The problem is really small.
"Private morality does not mean everything. If you have the chance, you can get rid of it." At the beginning, the zipper door failed to pull the person down, indicating that sometimes such personal morality is not as shocking as imagined.
"Good boss," Double Star said indifferently.
After all, it is still far away from the time when the Republican Party is in power. The Double Star has enough time to operate, and if it does not work, it will blame the Democratic Party again.
"Boss, there may be something here that you need to take care of yourself." Suddenly, Shuangxing's voice was particularly solemn, which was very rare.
After the dual-star sound module has voice and intonation, even if it was the original island city attack, the dual-star is not bad.
Rare means rare, solemn means serious.
"What's the matter?" Guan Ming stopped, a little curious.
The doorway was less than ten meters in front. Although the window was covered by curtains, it couldn't stop the light. Guan Ming knew that someone in the house was waiting for Guan Ming, waiting for him to go home.
"Since the network satellite took off, I have been collecting all the information that can be collected in the universe. Tonight, at 21:37:52 seconds, a laser pulse signal was collected. I thought this was just an ordinary signal. But just now, I received the same laser pulse signal! "
"The most important thing is that the source and internal arrangement of the two laser pulse signals are the same, and I can't convert this laser pulse signal into readable information at this time!"
Double Star's voice was heavy and a little disturbed.
Technology is an interest and a hobby for Guan Ming.
Sky, earth, ocean, Guan Ming wants to understand these unknowns, but just wants to understand these unknowns, but after hearing the words of double stars, Guan Ming shivered coldly, a little Ye Gonghaolong mean.
"... You mean, are there any aliens?" Guan Ming's voice was a little dry.
Nature can change the sea into mulberry fields, and nature breeds countless miracles.
But as the German philosopher Brenitz put it: "There aren't exactly two leaves in the world."
Guan Ming absolutely doesn't believe that nature will happen so coincidentally!
"Most likely, depending on the direction, I can confirm that the signal source is near Sagittarius twice!" Double Star immediately gave the answer.
Sagittarius is an astronomical name, and it has become the Sagittarius in astrology and is located in the widest and brightest part of the Milky Way.
At present, there is a common understanding in the scientific community that the core of the Milky Way is a supermassive black hole (Sagittarius A), and the entire Milky Way is orbiting this black hole, just like the Earth orbits the Sun and the Moon orbits the Earth.
With the Earth as the center, the center of the Milky Way is inside the Sagittarius.
With Sagittarius A as the coordinate, it is about 26,000 light years away from the earth, which means that this laser pulse signal was sent 26,000 years ago.
"This news is very important. Don't divulge it first, pay close attention to the research on this signal by other scientific research units." Guan Ming couldn't help walking back and forth at his doorstep.
"I know the boss, but rest assured, although this signal is repeated twice, each time lasts only 0.72 seconds. Even if it is monitored by a scientific research unit, they want to find these two identical ones in the face of massive monitoring data. The signal is also a needle in a haystack. "It wouldn't be possible to find the binary star if it didn't have a huge amount of calculations.
"Well, but you still have to pay more attention." Nodded, although Guan Ming wanted to smash all the scientific research institutions around the world who could monitor this signal, but he is not almighty, this is not Guan Ming alone He even faintly expected scientists to notice and discover this signal.
"Is there no way to analyze the permutations and combinations in a mathematical way?" Guan Mingte wanted to smoke at this moment, so he was very irritated, but unfortunately he did not have any smoke at the same time, and his wife was still pregnant.
"Sorry ~ EbookFREE.me ~ There is no way to forcibly decipher. This laser pulse signal is an open type of information transmission. Assuming there is a third or more extraterrestrial civilizations in the Milky Way, first of all, there must be a common Language, or consensus, for example, half a catty in ancient China was equal to eighty two, but now half a catty is fifty-two. "
"This is the first time we have been exposed to the information of a suspected extraterrestrial civilization. We cannot understand the meaning conveyed by the other party, even in a mathematical way." Shuangxing said with regret.
Cryptography is an interdisciplinary field. The most important part of it is mathematics. The most famous cryptography is probably Morse code, which is composed of 'dot' and 'line'.
However, Morse code is only composed of two basic signals, but the laser pulse is essentially stimulated radiation to generate amplified light. How to define 'points' and 'lines' is difficult, especially in the short time of 0.72 seconds.
In microseconds? Or by the number of photons? But what is certain is that the composition of this signal is definitely more than two elements: ‘point’ and ‘face’!
Do not expect aliens to speak Chinese, nor do they expect English to be spoken by aliens.
On a small earth, from the perspective of human history, there have been 5000+ languages ​​that have appeared and have been identified. What about alien civilization?
"If you don't research it, you have to study it. Increase the amount of calculation to study. Send all the information of this laser pulse signal, and I will see what is going on." There was some blood in my heart, Guan Ming ordered.
"Good boss." As soon as the voice fell, Guan Ming's electronic glasses appeared a lot of information about the laser pulse signal.
"Boss, actually ... you can ask Miss Er to inquire." Double Star's hesitant attitude was obvious.
"Well? Ask her what to discuss?" Sitting on the steps in front of her house, Guan Ming's first reaction was, is the alien related to the medical field?
