Earth Era

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

But Zhao Lan searched and found only forty-nine. That remaining spot of light could not be found anyway. In order to allow his busy father to take time to take him to the playground, the young Zhao Lan sat on the ground unwilling to admit defeat, and searched for the photo for an entire morning, line by line, pixel by pixel. A pixel search. Finally, in a corner of a certain row and a certain column, Zhao Lan found a light spot that was slightly brighter than the surrounding pixels.

That is a very small difference. If Zhao Lan hadn't calmed down and kept looking for it, Zhao Lan would not have discovered this. Zhao Lan, who found this light spot, excitedly told his father about the discovery. Perhaps he couldn't bear to discourage his enthusiasm. His father still used his work authority to align the observation angle of the telescope at the bright spot shown in the photo. , so... he really discovered a distant and ancient quasar.

This quasar is too far away. Although it is extremely powerful, the light it emits has traveled a long journey of 10 billion light-years. When it reaches the earth, it can only be enhanced by only one point on the film of a high-precision telescope. The brightness of the pixel. The difference is so small that even electronic programs ignore it. But it is only regarded as a product of light pollution or gravitational lensing, and it has not been analyzed in detail. But it did not miss Zhao Lan's search. It was Zhao Lan's work that morning that added another number to the list of stars in human civilization.

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

At this moment, more than 20 years have passed since this incident. The strong and energetic father in the past has long since passed away due to illness, but this incident has been buried deep in Zhao Lan's memory. This quasar means a lot to Zhao Lan. It means not only the dreams of childhood, but also the loving and generous gaze of the father.

but now. It disappeared under Zhao Lan's gaze, and disappeared without a sign, just like when his father left him.

Zhao Lan left his office, and after reporting the incident to the person in charge of the observation base, Zhao Lan was given higher authority to call for a higher usage share of the sky survey telescope. In addition to observations in the optical band. Zhao Lan has also obtained the right to use telescopes in gamma rays, soft X-rays, hard X-rays, and infrared wavelengths.

Zhao Lan can be sure that the position and direction parameters he entered into the telescope console are absolutely correct. But no matter what type of observation it is, what it returns is nothing but darkness. All the observation results clearly told Zhao Lan that there was nothing in that direction that could be detected by human civilization.

But... Zhao Lan's past observation records clearly recorded that there was a quasar in that direction, in that position. Even, just two hours ago, Zhao Lan was still staring at it.

The vastness and depth 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 have a look and see what was going on there. What kind of existence can devour a powerful quasar. However, Zhao Lan also knew clearly that the term 10 billion light-years meant more than just the distance in space. It also means distance in time. Ten billion light-years means that the light transmitted from there to Earth was emitted ten billion years ago. Even if you can get there. I don't have the ability to go back to 10 billion years ago...

What is going on in the universe?

Obviously, it is impossible for a powerful quasar to disappear for no reason. Quasars consist of a supermassive black hole at the center and an accretion disk orbiting it, bound by its powerful gravity. Quasars are only a few light days in diameter. Its radiation power is much stronger than that of the Milky Way, which is 100,000 light-years in diameter. Its radiation power comes from the mutual collision and friction of the materials in the accretion disk, whether it is the radiation in the visible light band or the radiation in other bands.

Well, of course a quasar will "die". When it finally devours the matter in the accretion disk around it, the central black hole will quiet down and stop releasing the radiation, and people will naturally not be able to observe it. It's just... It took only ten minutes for this quasar to go from normal luminosity to complete disappearance, ten minutes... How could it possibly complete the long journey from robustness to death?

This is absolutely impossible. But why did it disappear?

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

"Perhaps a dust cloud just happened to pass by and blocked the radiation of this quasar." Zhao Lan thought so, comforting herself, "It only takes a few days at most, and that dust cloud will disappear. It will float away and the quasar will reappear."

It is not uncommon for stars to disappear because of dust clouds. In the most obvious example, humans have not been able to see the core of the Milky Way from visible light until now because of the obscurity of dust clouds. However, if the quasar disappeared because of the dust cloud, then its situation is different from that of the Milky Way's core. Obviously. The dust cloud did not block the quasar before, but now it blocks, so it must have motion. And if it has motion, then it must continue to move until it leaves the occlusion path.

But there are some flaws in this explanation. Because the dust cloud is unlikely to block the radiation of all wavelengths, and now, Zhao Lan can't see this quasar no matter what kind of telescope he uses.

"Continue to wait for a while." Zhao Lan thought.

Then Zhao Lan waited for more than a month. For more than a month, Zhao Lan took time out every day to observe this quasar. But Zhao Lan always found nothing. With nothing to do, Zhao Lan only wrote a work report. This report was submitted to the Central Academy of Sciences, hoping to use the power of the Central Academy of Sciences to find a reasonable explanation for this matter.

After this matter was temporarily over, Zhao Lan once again received a message from Xu Ming, the person in charge of Mars Port.

"Ms. Zhao Lan, hello, in accordance with the requirements of the current laws of human civilization. Let me update you on the latest developments regarding the theft of your Sylvia spacecraft."

Xu Ming's appearance hasn't changed much, but the hair on his head has become thinner. It seems that Xu Ming has been devastated by the theft of the spacecraft.

"After we have conducted a lot of investigations with government departments, we have basically determined that Li Yunfan did this." Xu Ming said with a wry smile, "Because we found some unique methods of committing crimes within the Mars Port, And some marks he left on purpose to declare his identity. Yes, Li Yunfan stole your spaceship, but we still don't know why."

"And the department responsible for tracking the whereabouts of the spacecraft has not made much progress. We have done a lot of work. Finally, we have locked the place where the spacecraft last appeared, which is only three million kilometers away from the earth. The monitoring range of Space Base 08 is out. Any flying instruments entering or leaving the earth from this direction will be checked and recorded by Space Base 108, but Base 108 has not recorded any data about your spacecraft. In After that time period, all the recording equipment in our civilization has not seen your spacecraft again. That is to say. After the Sylvia spacecraft arrived near the observation base No. 108... suddenly disappeared. No one knows. Where did it go, no one knows what method Li Yunfan used to achieve this. Several months have passed by now. We still can't trace any clues."

Zhao Lan's heart moved slightly when he heard Xu Ming say this. Because Zhao Lan found out. There seems to be something in common between the Sylvia spacecraft and the disappearance of that quasar. What this has in common is that both of them disappeared suddenly and inexplicably, with the power of human civilization. No reasonable explanation could be found for this disappearance.

But Zhao Lan then dismissed the idea. If there is any connection between a quasar 10 billion light-years away and a small modern spacecraft of human civilization, this is the most incredible thing.

"This is probably a coincidence." Zhao Lan thought.

"We are still investigating this matter, but I will say this in my personal capacity, Ms. Zhao Lan, you should not have any illusions about retrieving your spaceship." Xu Ming said, "Li Yunfan is too mysterious, unless He came out on his own, otherwise we probably wouldn't be able to catch him..."

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

Although I regret the theft of the Sylvia spacecraft, Zhao Lan is an easy-going person and doesn't want to be too embarrassed.

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

After a pause, Xu Ming continued hesitantly, "Ms. Zhao Lan, there is one thing we think we should tell you in advance...that is...you are famous."

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

Xu Ming said with a wry smile: "Ms. Zhao Lan, you know, as the most legendary thief, Li Yunfan has many ardent fans and a high degree of attention in our society, anyone who is involved with Li Yunfan will attract the attention of the public. The same is true now, Li Yunfan used all kinds of incredible means to finally steal one of your ordinary spaceships. The matter has been dug up by the media... and has been reported and spread to the society. You know , this is the first time that Li Yunfan has had a relationship with a young, beautiful and beautiful lady like you, and because you are the only direct descendant of Zhao Huasheng, the savior of mankind, your identity is quite special... So now, in society, you have There has been a lot of speculation between you and Li Yunfan, you are now... more famous than a star."

"Which media reported this and brought up my name?" Zhao Lan's mind suddenly burst into anger: "I'm going to the court to sue them for violating my sexual rights!"

Li Yunfan is a very legendary thief~www.readwn.com~ Until now, no personal information about Li Yunfan has been leaked except for this name. Each of the cases he has made is bizarre and earth-shattering, but these cases have one thing in common, that is, these cases have no social harm, and no one has suffered because of Li Yunfan's cases. Strictly speaking, these cases of Li Yunfan are more like 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. Under such circumstances, Zhao Lan was implicated, and because of Li Yunfan, it became a natural thing to be noticed by the public.

"This matter is also due to our improper handling of confidentiality measures." Xu Ming continued with a wry smile, "We will cooperate with your accusation and provide you with all the accusation evidence you need. At the same time, because of our work mistakes And for the trouble it brings to you, we will also give you proper compensation..." (To be continued.
