Chapter 195: The First Communication with an Alien in History
"Hey, Mom, I'm not going back for the New Year this year...... Yes, if there is an emergency, I will take the time to go back in the next year...... Okay, okay, bring your daughter-in-law back when the time comes, and you won't forget it......"
The New Year is approaching, and with the approach of that alien battleship, it is obvious that Lu Yi will not have time for the New Year.
In the voice of Lu's mother's complaint, Lu's father stopped Lu's mother's voice, Lu Yi hung up the phone, reached out and rubbed his eyebrows, and continued to check the data on the screen.
Now that the battleship had crossed the orbit of Pluto, it seemed that the goal was to go to Jupiter, but at this time, the battleship, Jupiter, and Earth were in the same straight line, and no one could be sure that the other party was not coming to Earth.
"What happened to this? Could it be that the warship was damaged due to the war, and had to enter the solar system to repair the spaceship, but the damage surface is not like being bombarded by mass cannons, but is a bit like hitting a meteorite. ”
Lu Yi looked at the newly detected images of the warship, and after the other party crossed the Kuiper Belt into the solar system, without the dust and meteorites of the Kuiper Belt, the other party's traces were completely exposed to the sight of human beings at once.
It's just that to the surprise of mankind, it is not a heavily armed warship that enters the solar system, but a dilapidated warship.
This situation was not only a little unexpected by Lu Yi, but also a little unexpected by everyone, which also made the original other party not war, recuperate, and peaceful exchanges suddenly increase.
"Is it really here to repair the battleship, not malice?"
An idea came to Lu Yi's mind, opening the image information that had captured the battleship before, especially after the other party sent out an active detection.
"What is this?"
Suddenly, two anomalous pixels on an image attracted Lu Yi's attention.
According to calculations, this is an object with a diameter of about 30 centimeters, but at such a long distance, even with the most advanced scanning detection array, this object is only two pixels in the image.
Such pixels are generally classified as useless information in detection, because they are too small and too blurry.
And it is in the Kuiper belt, the starry sky is full of dust, and it belongs to the breeding ground of meteorites, so even if the explorers see it, they will subconsciously ignore it, thinking that it is the gathering of starry sky dust or small meteorites in the Kuiper belt.
Lu Yi had a bit of an obsessive-compulsive episode, so he retrieved all the historical images in this direction, and after comparison, he found that the previous scanned images did not appear these few pixels.
"What the other party threw down? Or is it a meteorite that was previously obscured? ”
Lu Yi, who felt that he had found something, calculated the speed and course of this unknown object according to the only 4 images that scanned this anomalous object, according to the scanning time of the images, and the change in the orientation of the object when the scan was found.
"The speed is about 60 meters to 200 meters per second, which is not much difference in the speed of most meteorites in the Kuiper belt, but the orbit is ......."
Lu Yi looked at the calculated orbit, if there was no collision, the orbit of this item was similar to the orbit of most comets, it was an ellipse.
However, Lu Yi retrieved the previous scanned images according to this orbit, and did not find this item on this orbital path.
"In this case, then this unknown item is most likely thrown by this battleship, so it's very interesting."
Lu Yi kept turning one thought after another in his mind, in interstellar voyages, any material is precious, and it will not be thrown away when things are used up like on Earth, but will be reused when they are used up.
Even if it is feces and urine, it will be collected, and then the material elements in it will be reclassified and reused.
During interstellar travel, it's likely that the water you drink is actually the water in the feces or urine you pulled 5 minutes ago.
Forget about throwing it, but the initial strength and angle of this throw are obviously strictly calculated, and they are thrown out according to the speed and orbit of most meteorite comets in the solar system.
"The other party is deliberately covering up this thrown object!"
After thinking for a while, Lu Yi affirmed his guess, if the strength and angle of the throw were not so rigorously calculated, it could still be said that the loose parts of the damaged side of the opponent's battleship were collided and dropped by a small meteorite.
But in such a situation where it was thrown out after strict calculation, it is undoubtedly certain that the other party is deliberately covering up something.
If you hadn't stumbled upon each other's tracks before that, and then had already established a large scanning and detection array on the moon, in space orbit, and on the ground, you wouldn't have been able to scan this small object with a diameter of less than 30 centimeters.
If the other party's active detection behavior was discovered at that time and did not track it with all the scanning arrays at the first time, then even if it was discovered later, it would not have associated this item with this alien battleship with this parameter that is no different from a meteorite comet.
"Commander Lu, there is the latest situation, the other party took the initiative to launch electromagnetic wave communication!"
While Lu Yi continued to guess the other party's purpose, suddenly a staff member hurriedly ran over to report to him.
"Unsolicited contact?" Lu Yi's eyes froze slightly, saved the results of his analysis, and hurriedly stood up and walked inside.
"What's going on now?"
Walking inside, all the personnel were busy, Lu Yi looked at the information on the big screen, and asked Lao Su a word.
"Five minutes ago, the other side launched a large laser screen board, on which the information was repeatedly flashing, and through preliminary analysis, this information belongs to the language dictionary."
Lao Su hurriedly replied, 5 minutes here refers to the time to detect the laser screen, not the time when the alien warship actually launches and unfolds the laser screen plate.
According to the speed of light, the other party has just crossed Pluto, and there is still a distance of nearly 4 light hours from the earth, and the actual time to launch the laser screen plate should be 4 hours ago.
It's the same as the sunlight seen on Earth is actually emitted by the sun 8 minutes ago.
Lu Yi nodded and didn't bother anymore, he is not an information expert, and Lao Su can only be counted as half, if he really wants to decrypt the language dictionary sent by the other party, the group of scientists in front of him who have a little cold scalp are.
Half an hour later, Professor Hill took a tablet over, handed the tablet in his hand to Lu Yi and said, "It's a language dictionary, but it's a language dictionary that has been processed, and it doesn't have much valuable information on it." ”
The meaning of a language, a text, every pronunciation and every symbol is given by intelligent life, and if you want others to understand your own language, you must tell each other the meaning you give to each sound and symbol.
That is to say, a complete language dictionary, in addition to the content of various language words, these contents must be accompanied by images to be used.
For example, human Chinese, write "sun" two Chinese for others to guess the meaning, in addition to people who have learned Chinese, others, including aliens, will also be stupid when they see it.
But if you write the word "sun" and then draw an image of the sun next to it, then others will be able to understand it, and even if you are more proficient, you can directly use "day" to represent it.
This process of giving meaning to words and symbols and pronunciation language can reveal a lot of information about this civilization, and from the explanation of some words, we can get the general form of the life of this civilization, from the explanation of some nouns, we can know the general system of this civilization, and even from some words, we can also know the degree of science and technology of this civilization.
But it's a pity that now the language dictionary sent by this alien warship has been analyzed, and it is obviously a processed dictionary, and the civilization information that can be revealed on it is almost equal to 0.
Lu Yi pondered for a moment and ordered: "Send a communication in the other party's language dictionary, ask the other party to explain the purpose of entering the solar system, and ask the other party not to cross the orbit of Jupiter!" ”
Jupiter's orbit is 630 million kilometers from the Earth, and with such a long distance, coupled with the interstellar dust that fills the asteroid belt, even high-energy light weapons will have to attenuate most of their energy, so they cannot pose much threat to the Earth.
As for the mass cannon, although the energy attenuation of the actual matter in space is very low, the speed of the mass projectile is below the speed of light, which can be scanned in advance, and humans will have enough reaction time to intercept it after such a distance.
"Yes."
A technician next to him answered, and Hill also nodded in agreement with Lu Yi's proposal, which is the safest choice for humans.
Drip.....
Before the technician could compile the communication according to the language dictionary of the other party and send it out, the radio scanning array in space detected a regular electromagnetic wave.
The information of the electromagnetic wave is not encrypted, the system automatically matches the information, and the matching language dictionary displays the information content contained in this paragraph of electromagnetic wave.
[Hello respected civilization, we are the exchange ship of the blue civilization.
When we were traveling in the interstellar space, due to the failure of the detection system, we collided with an interstellar wandering meteorite at high speed in the outer space of the galaxy, resulting in serious damage to the AC ship, hoping to replenish the material in your galaxy and stay for a period of time to repair the hull, in exchange, we can use some scientific and technological data information as a reward. 】
Everyone in the entire hall stopped what they were doing, looked at the communication of the first alien civilization in the history of mankind, and then turned their eyes to Lu Yi.
Lu Yi's eyelids twitched twice as he looked at the information displayed on the screen, this was really a meteorite......
