Zhao Lan is the discoverer of this quasar. Zhao Lan still remembers that at that time, when he first entered his father's research institute, perhaps because his father thought he was too naughty and did not let himself affect his work, so his father gave him a photo after technical processing, and told himself that if he could find the fifty hidden points of light from it, his father would take him to the playground on weekends to play.

But Zhao Lan searched and searched and only found forty-nine. The remaining spot of light could not be found anyway. In order to allow his father, who has always been busy, to take time to take him to the playground, the young Zhao Lan sat on the ground and searched for the photo for a morning, line by line, pixel by pixel. Eventually, in a corner of a certain row and column, Zhao Lan found a spot of light that was slightly brighter than the surrounding pixels.

It was a very small difference, if it wasn't for Zhao Lan calming down and looking for it, Zhao Lan would not have been able to find this. Zhao Lan, who found this point of light, excitedly told his father about this discovery, perhaps because he couldn't bear to discourage his enthusiasm, his father still used his work authority to aim the telescope's observation angle at the bright spot shown in the photo, so he ...... He did discover a distant and ancient quasar.

This quasar is so far away, and although it is extremely powerful, the light it emits after a long journey of 10 billion light-years can only be enhanced by a pixel on top of the negatives of high-precision telescopes. The difference is so small that even electronic programs ignore it and simply treat it as a product of light pollution or gravitational lensing, without analyzing it in detail. But it didn't miss Zhao Lan's search. It was Zhao Lan's work that morning that added another number to the list of stars of human civilization.

His father led Zhao Lan to the playground for a whole day as promised, and Zhao Lan's door to the astronomical world was also opened. It was precisely because of this incident that Zhao Lan embarked on the same path as his father in the future and also became an astronomer.

At this moment, more than 20 years have passed since this incident, and his father, who was strong and energetic in the past, has already left him because of illness, but this incident has been buried in the depths of Zhao Lan's memory. This quasar means a lot to Zhao Lan. It means not only the dreams of youth, but also the loving and generous gaze of my father.

But now, it disappeared under Zhao Lan's gaze, and disappeared without the slightest warning. Just like when my father left him.

Zhao Lan left his office, and after reporting the matter to the person in charge of the observation base, Zhao Lan was given higher authority to call on the higher share of the Sky Survey Telescope. In addition to the observation of the optical band, Zhao Lan also obtained the permission to use the telescope of gamma rays, soft X-rays, hard X-rays, infrared bands and other radiation fields.

Zhao Lan can be sure that there is absolutely no error in the position and orientation parameters he has entered into the telescope console. But it doesn't matter what type of observation. All that was returned was blank, all darkness. All the observations clearly told Zhao Lan that there were no objects in that direction that could be detected by human civilization.

But...... Zhao Lan's previous observation records clearly recorded that in that direction, in that position, there was obviously a quasar, and even, just two hours ago, Zhao Lan was still watching it obsessively.

The vastness and profundity of the universe made Zhao Lan feel a little powerless. When all of Zhao Lan's search attempts failed, Zhao Lan even wanted to go to that place to see it in person. See what's going on there, what kind of being can swallow a powerful quasar. However, Zhao Lan clearly knows that the word 10 billion light years does not only mean spatial distance, but also temporal distance. Ten billion light-years means that the light that came to Earth from there was emitted 10 billion years ago. Even if he could reach that position, he would not have the ability to go back to 10 billion years ago......

What is going on in the universe?

Obviously, a powerful quasar can't disappear for no reason. A quasar consists of a supermassive black hole in the center and an accretion disk orbiting it and bound by its strong gravitational pull. The quasar is only a few light-days in diameter, but its radiation power is much stronger than that of the Milky Way, which is 100,000 light-years in diameter. Its radiant power comes from the collision and friction of accretion disk materials, whether in the visible band or in other bands.

So. Of course, a quasar will "die". When it finally swallows up the material in the accretion disk that surrounds it, the central black hole will quiet down and no longer emit any more radiation, and people will naturally not be able to observe it. It's just that...... It took only ten minutes for the quasar to go from normal luminosity to complete disappearance. It's only ten minutes...... How is it possible to complete the long journey from robustness to death?

This is absolutely impossible. But why did it disappear?

Zhao Lan finally gave up the idea of continuing to search. Zhao Lan left the operation room, wrote an observation log in his office, recorded what he saw and heard today, and then went back to prepare for rest.

"Maybe a cloud of dust happened to pass by there and blocked out the quasar's radiation." Zhao Lan thought like this and comforted herself like this. "It will only take a few days at most, and the dust cloud will drift away, and the quasar will reappear."

It is not uncommon for stars to disappear due to dust clouds in the universe. One of the most obvious examples is that until now, humans have not been able to see the core of the Milky Way from visible light because of the obscuration of dust clouds. However, if the quasar had disappeared because of a cloud of dust, it would have been in a different situation than the Milky Way core. Obviously, the dust cloud did not obscure the quasar, and now that it does, then it must be in motion. And if it is in motion, then it will inevitably continue to move until it leaves the obscured path.

However, there are some loopholes in this interpretation. Because the obstruction of the dust cloud is unlikely to block the radiation in all bands, and now, Zhao Lan cannot see this quasar from any kind of telescope.

"Let's keep waiting." Zhao Lan thought so.

Then Zhao Lan waited for more than a month. For more than a month, Zhao Lan would find time every day to observe this quasar. But Zhao Lan never found anything. With nothing to do, Zhao Lan had no choice but to write a work report and submit this report to the Central Academy of Sciences, hoping to find a reasonable explanation for this matter with the help of the Central Academy of Sciences.

After this matter is over for the time being. Zhao Lan once again received a message from Xu Ming, the person in charge of Mars Port.

"Hello Ms. Zhao Lan, in accordance with the requirements of the current laws of human civilization, I would like to inform you of some updates on the theft of your Sylvia spacecraft."

Xu Ming's appearance has not changed much, but the hair on his head is more thin. It seems that Xu Ming has been overwhelmed by the spaceship theft case for a period of time.

"After we conducted a lot of investigations with government departments, we have basically determined that Li Yunfan did this matter." Xu Ming said with a wry smile, "Because we found some of Li Yunfan's unique methods of crime inside Mars Harbor, as well as some marks that he deliberately left to declare his identity. That's right, Li Yunfan stole your spaceship, but we still don't know why. ”

"And the department responsible for tracking the ship's whereabouts hasn't made much progress. We did a lot of work to finally locate the last place where the spacecraft appeared, which was only three million kilometers away from Earth, and was already under the surveillance range of Space Base 108. Any instruments flying in and out of Earth from this direction will be inspected and recorded by Space Base 108, but Base 108 does not record any data about your spacecraft. After that time period. None of the recording devices in our civilization have seen your ship again. That is, after the Sylvia spacecraft arrived near Observation Base 108...... Suddenly it disappeared. No one knows where it went, and no one knows what kind of means Li Yunfan used to do it. Months have passed now, and we still haven't been able to trace a single clue. ”

When listening to Xu Ming say this, Zhao Lan's heart moved slightly. Because Zhao Lan found that there seemed to be some kind of commonality between the Sylvia spacecraft and the disappearance of the quasar. The common denominator is that both of them have disappeared suddenly and inexplicably, and with the power of human civilization, there is no way to find any rational explanation for this disappearance.

But Zhao Lan then dispelled this idea. Between a quasar 10 billion light-years away and a small modern spaceship of human civilization. If anything, they're the most incredible thing.

"It's probably a coincidence." Zhao Lan thought so.

"We are still investigating this matter, but I would like to say it in my private capacity, Ms. Zhao Lan. Don't have any illusions about getting your ship back. Xu Ming said, "Li Yunfan is too elusive, unless he comes out on his own, we probably won't be able to catch his ......."

"Okay." Zhao Lan replied, "I know it's not your fault. As long as you finally compensate me for my new ship, I promise not to pursue this matter further. ”

Although there is some regret for the theft of the Sylvia. But Zhao Lan is an easy-going person and doesn't want to embarrass Xu Ming too much.

"Thank you for your cooperation." After a communication delay, Xu Ming's figure appeared on the communication instrument again, and bowed to Zhao Lan repeatedly: "We will definitely deliver the new spaceship to you as soon as possible." ”

After a pause, Xu Ming continued with some hesitation: "Ms. Zhao Lan, there is something that we think we should tell you in advance...... That's ...... You're famous. ”

"Me? Am I famous? Zhao Lan felt a little inexplicable at this sentence.

Xu Ming said with a wry smile: "Ms. Zhao Lan, as you know, as the most legendary thief, Li Yunfan has many fanatical fans and extremely high attention in our society, and anyone who is involved with Li Yunfan will receive public attention. Now the same is true, the fact that Li Yunfan used all kinds of incredible means to finally steal one of your ordinary spaceships has been unearthed by the media...... And it has been reported and spread to society. As you know, this is the first time that Li Yunfan has had a relationship with a young and beautiful lady like you, and since you are the only direct descendant of Zhao Huasheng, the savior of mankind, your identity is also quite special...... So now, there have been a lot of speculations in society about you and Li Yunfan, and you are ...... More well-known than celebrities. ”

"What media outlets have reported on this and mentioned my name?" A wave of anger suddenly appeared in Zhao Lan's mind: "I'm going to the court to sue them for violating my ** rights!" ”

Li Yunfan is a very legendary thief, and until now, except for this name, all personal information about Li Yunfan has not been leaked. Every case he made was bizarre and earth-shattering, but these cases had one thing in common, that is, these cases did not cause any social harm, and no one suffered because of Li Yunfan's cases. Strictly speaking, Li Yunfan's cases are more like some pranks. One is because of the mystery, and the other is because of the entertainment of the prank, Li Yunfan naturally has a very high reputation, and even has many fanatical fans and admirers. In this case, Zhao Lan was implicated, and it became a natural thing for Li Yunfan to be concerned by the public.

"This matter is also due to our mishandling of confidentiality measures." Xu Ming continued to smile wryly and said, "We will cooperate with your accusation, provide you with all the evidence you need for the accusation, and at the same time, we will also give you proper ......compensation for the trouble caused to you by our work mistakes." )
