"Electromagnetic signals that appear out of nowhere? Where are the estimated signals? Isn't it exploring the edge? Yan An felt that something was wrong when he heard it.

Pulsars are the collapsed cores of massive stars that die during supernova explosions, and they cannot be formed suddenly, and it is difficult to use the word sudden for the observation of the eye of the sky, which feels like there is a sudden addition of people in your field of vision.

And this is even more outrageous than one more person - a pulsar appeared out of thin air.

But this is obviously impossible, so there is only one explanation, this electromagnetic signal does not come from a pulsar, but a mysterious signal that really appears out of thin air.

Gao Shenghan on the other end of the phone paused, "It's not on the edge of detection, but it's very, very close to us, estimated to be about a light-year away, because the electromagnetic signal is comparable to the speed of light, so this signal should have been sent a year ago, and we suspect that the source of the signal may no longer be in the place where the signal was sent." ”

Just appeared so close? Yan An frowned, the distance of just a year is extremely long for human beings, but it is only a small distance for the universe.

If it is an alien civilization spaceship, it is a very dangerous thing to find out at this distance, which shows that the other party has a high probability of mastering the method of traveling at high speed in the universe, otherwise it is impossible to suddenly appear and be discovered.

Could it be that Mingxing's people persistently sent an exploration spacecraft to find him after receiving the distress signal back then?

Yan An suddenly had such an idea in his head, and immediately got up and quickly replied, "Okay, I know, now go to the algorithm building and let them send us the signal they receive." ”

There is nothing to keep secret about this kind of thing, Zhu Chitianyan can receive it, and the Tianyan of the regent country can also receive it, and because the other party may be an extraterrestrial civilization, in comparison, the countries on the Blue Dome Star are a family, so there is still a lot of communication in this regard, basically to jointly promote research.

After saying this, Yan An got up and washed up hopefully.

"BT, did you think it was possible that someone from Mingxing came to us? We've all been shipwrecked for so long, and the spaceship they sent should have arrived, right? ”

His expression was excited and he wanted to get an affirmative answer, but BT poured a bucket of cold water on him, "Your Excellency, according to the analysis of the rescue plan of the wrecked spacecraft by Mingxing before the sixteen turbulent cycles of the Blue Dome.

Before the crash, the spacecraft with stable communication and clear positioning shall not exceed five Ming Star orbital periods.

The maximum search and rescue time for spacecraft that has stable communication before the crash but cannot be located shall not exceed four Ming Star rotation cycles.

The maximum search and rescue time for a spacecraft that has unstable communication and cannot be located before the crash shall not exceed three Ming Star rotation cycles.

It has been 16 times since we encountered the accident, and it is estimated that it is 10 times for the Ming Star, which has long exceeded the maximum search and rescue period of the rescue plan, and the probability that the unknown signal source is the Ming Star rescue spacecraft is only 0.1 percent. ”

The approximate location of the wrecked spacecraft can be clarified, indicating that there is a high probability that Nu Effort can be found, so the search and rescue time is the longest.

And a spaceship like theirs, which had unstable contact and could not be located before the crash, is equivalent to looking for a needle in a haystack, and it is obviously irrational to waste manpower and material resources on this.

As for the signal source being sent by Mingxing's Pioneer spacecraft when it came to explore, it is even less likely.

After all, this is an unknown realm, and even if Mingxing is persistently exploring outward, it is unlikely that he will find this place in sixteen years.

What's more, according to the exploration rules of Mingxing, the Pioneer spacecraft cannot maintain sub-light speed and light speed when exploring outward, at most only one-tenth of the speed of light, these years, it is enough to expand the scope of Mingxing's external exploration, and it is still far away from the Blue Dome.

BT is the intelligent management system of the Pioneer spacecraft, and it is very clear that according to the interstellar ramjet engine used by the Pioneer spacecraft, even if it has been traveling at the speed of light, Mingxing has explored at most sixteen light years over the years.

And the distance between the blue dome and the Ming star is far more than sixteen light years.

Being said like this, the smile on Yan An's face cooled down as he became more disappointed, from a rational point of view, this possibility is really unlikely, especially when it is not even certain whether the signal source is an alien spacecraft, this is his wishful thinking.

"I see." After adjusting his mood, Yan An prepared and went straight out to school.

Yan An met Gao Shenghan in the algorithm building, there are only the two of them here for the time being, Li Junwei and others returned to Liangxi for a vacation after the work in Pingjing was completed, it happened that today was New Year's Day, and they had a break for six days in a row, and they would not come to Nandu tomorrow to officially resume work.

"This is the signal received by the Sky Eye? It does seem to have a certain regularity, but why did you think of asking me to decipher it? In Gao Shenghan's eyes, Yan said after looking at it for a while.

The regularity in his mouth, Gao Shenghan didn't see it, he didn't understand this after all, he thought that Yan An was also pretending, but after thinking about it, the person in front of him was Yan An, and inexplicably felt that he might really understand.

"In fact, there are many research institutions deciphering this signal at the same time, after all, it is too close to us, and the upper authorities are still paying more attention.

What Vice Minister Han means is that if you are interested, you can try to decipher it at your leisure, and if you are not interested, you can start a new project tomorrow. ”

"Leisure time? What if I'm really interested in getting involved? ”

"That depends on what Vice Minister Han means, but it should satisfy you......" Gao Shenghan looked uncomfortable, and he didn't have the right to decide, if he could, he naturally wanted Yan An to choose a project with more money and less life.

"Okay, but I don't think there's much value in deciphering this thing, and even if it's an alien message, it's impossible to get useful content."

The humans of Dome have always been keen to decipher extraterrestrial signals in their own language, and they were thrilled for a long time in the last century just by receiving a signal similar to "WOW", only to later prove that the signal was formed by comet interference.

This kind of behavior is actually no different from self-orgasm.

The people of the two countries on the Dome are still reluctant to understand each other's cultures, and they don't know how they think that aliens are keen to understand the culture of the Dome and communicate with them in the language of the Dome.

From a certain point of view, this can also be regarded as a "general letter star".

Then again, there must be at least 6,000 languages and 2,700 scripts on the planet.

If the alien civilization wants to communicate with them in the language and writing of the blue dome, will it feel too troublesome, and then the parties will fight for the blood in order to let the alien civilization communicate in their own language and writing, and a world war will directly break out?

Tsk, think about it, it's still possible.

"It's always going to be tried, this kind of signal is very regular, and it is more likely to be a signal of an extraterrestrial civilization than any signal we find now."

"Okay, don't be in a hurry about this, how is the cloud platform I want ready?" After being splashed with cold water by BT, Yan An was not interested in this signal.

According to the speed at which Mingxing opened the map, the signal source started to sail from the signal, and it has only traveled a tenth of a light year now, and there are at least nine years left to reach Mingxing.

It's not that there aren't faster ways to sail, black hole shuttles or warp engines can travel faster than interstellar ramjet engines, but even Mingxing, who developed these two technologies, has not applied them to the Trailblazer spacecraft.

There is no other reason, it is easy to have an accident, and a voyage of more than one-tenth of the speed of light can only be on the established interstellar route of the explored star field, otherwise the probability of an accident will increase with the increase of speed, and the consequences will also increase.

The most important thing about exploring the outside is stability, not just lighting up the map and everything will be fine.

If the source of the signal is really a ship that a civilization is exploring, then its top speed will never exceed one-tenth of the speed of light, and it will be a long, long time before it reaches the Emerald Dome.

"I outsourced it to a tanuki, and I just got it on yesterday.

However, your requirements are relatively high, they can't reduce the size and enhance the capacity of the transmission data stream, and the one-to-many high-efficiency connection required by the platform is not stable. ”

"Then wait for them to come back, replace the data stream transmission interface with several information flows, and then use the tree transfer topology to complete the platform sub-motherization."

The multi-session information flow is a special software-based way to transmit data information, including data conversion, data transmission, etc., and the ability to carry data flow can be improved without updating the hardware.

Of course, the increase is limited, and the use of several sessions of information without upgrading the processing equipment can increase the data transmission capacity by up to 40%, which is enough, as long as the BT is slightly closed.

The tree transfer topology is the result of the upgrade and strengthening of the existing tree topology of the Blue Dome, and the parent node establishes an effective and stable connection to the child node, which can solve the problems encountered in the platform sub-motherization.

Not only that, but the tree transfer topology has a greater role in multi-level platforms, most commonly in the management system of individual companies.

Yan An learned these two techniques in December, when Gao Shenghan reported to him the problems he might encounter, and in order to solve them, he learned them by the way, which was simpler than the factor factorization algorithm, but he learned it in two days.

"How many streams? Tree transfer topological state? When do you have a new study? ”

Since he met Yan An, he has not done research, either to deal with chores as a secretary, or to study with Yan An, and completely change from an excellent researcher to an administration - for no other reason, Zhu Xingguo feels that Yan An will like an administration that is not very official.

He couldn't figure out how Yan An did it, and throughout December, as far as he knew, Yan Anke had bought a lot of books, including "Frontiers of Inorganic Chemistry", "Modern Molecular Photochemistry", "Bioinorganic Chemistry" and so on.

These are all content that can only be learned by a master's degree in chemistry, and what I bought half a month ago were books related to physics, materials science, etc.

In other words, while Yan An was studying these books, he also took out two techniques for him.

In this regard, Gao Shenghan couldn't figure out how this was done.
