Pingtan in Guizhou, FAST base.

FAST, Five-hundred-meter Aperture Spherical radio Telesco, the full name is the 500-meter aperture spherical radio telescope.

Of course, it has a more popular name, "Sky Eye".

As the world's largest radio telescope, after the fall of Arecibo, it is the world's only radio telescope with a diameter of more than 300 meters.

In particular, the observation of pulsars has led to the discovery of hundreds of pulsars in just a few years, greatly filling the pulsar database.

The so-called pulsar, which refers to a neutron star that rotates at high speed and constantly emits electromagnetic signals, is generally believed to be caused by supernova explosions, but the new theoretical framework "accretion-induced collapse" also shows that supernova explosions are not the only way to form them.

Of course, FAST's capabilities go far beyond "targeting" pulsars, as its clever angle-adjustable design, large reflective surface, and highly sensitive feeds make it extremely good at observing neutral hydrogen regions.

Three years ago, the country announced that FAST was fully open to astronomers around the world.

Today, many astronomical teams from all over the world have come to the depths of the western mountains to cooperate.

……

"Samuel, can you ask Sita to put me two more pieces of candy next time?"

In the international cooperation base across the mountain from FAST, Li Lei held coffee that was more bitter than traditional Chinese medicine, and his face was constipated: "Didn't you say that people like sweets, why are you the opposite?" ”

"It's easy to gain weight when you put sugar."

Samuel took his coffee, leaned back on his desk, and took a sip without changing his face.

Their office is not big, only five or six positions, and now in addition to the two of them, there is Samuel's Sita and a graduate student from NTU who works here with their mentor.

It's the weekend, and they're still in the office, with little hard demand and a new suspicious pulsar — a place where the discovery of pulsars is nothing but something to be excited about.

Sita was bought by Samuel, who came from Venice, from a wealthy family of leather goods, his father opened a factory in Wenzhou, and he applied for a doctorate in astronomy at the University of Rome 1 Panthéonica to come to FAST.

The last time he robbed Sita, the whole office helped him out, so he kept his promise and made Sita a waiter in the office.

Li Lei is different from him, he is from P University, he has been working here for six years, he used to follow his tutor, and now he is "working alone", although he has sent a lot of papers, but he always feels that it is not interesting enough.

Doing astronomy, he must be able to live up to loneliness, anyway, he has been in this mountain for a few years, and his wife has no opinion, so he will naturally be happy to stay.

The two of them chatted casually, and Chen Xiang, the little sister of Nanda next to them, was holding a tablet to watch a video - they are located in the core area here, and they can't use mobile phones or wifi - but it's no problem to have a hidden hotspot indoors.

After all, the wifi signal, not to mention the next mountain, even if the wall is almost gone.

"Mr. Li, we should change the Ita system here, right?" Chen Xiang raised her head, she raised the tablet, and her face was full of interest: "Looking at the latest display of Jizhi Technology, the combination of the twin towers is really strong." ”

"It depends on whether the upper side is willing to spend money, and now we can't even run up to Aita's computing power." Li Lei said and glanced at his computer monitor.

——As a key project, FAST has a high demand for AI, computing power, and algorithms, so not long after ATA was launched, they enjoyed key care.

However, as Jizhi Technology provides more and more services, their computing power distribution is becoming more and more limited, and it is only now that Aita has been on quantum computers.

"Huh? Computing power? ”

Li Lei immediately sat upright, looking at the analysis progress that was only 10% five minutes ago, and now that it was completed directly, he immediately shouted: ", it's really up to you!" ”

Two others immediately stood behind him.

On the display, the data analysis is indeed complete.

Li Lei exhaled softly, ready to click on the report.

Just then, the phone on the table suddenly rang, startling him.

Picking up the phone, Li Lei clicked on the report at the same time: "Hey, which one?" ”

A young voice came from the phone: "Hello, are you FAST?" I'm Ye Ming. ”

"Well, yes...... Ye Ming? Do we know each other? Li Lei put all his attention on the report.

An embarrassed laugh came from the phone: "Well, it seems that we really don't know ......"

"Wait." Li Lei was stunned for a moment.

At this moment, the two people beside him also looked at him with shocked expressions at the same time.

Both of them heard the word "Ye Ming" in his mouth.

Li Lei's heartbeat instantly accelerated.

Ye Ming...... Is it Professor Ye Ming from the provincial exchange? ”

"Well, it's me, what do you call it?"

"Ah...... Hello Professor Ye......" Li Lei stood up instantly, and after taking a few breaths in succession, he forcibly suppressed his excitement: "My name is Li Lei, and I am an associate researcher of the FAST International Cooperation Laboratory. ”

"Hello Mr. Li." On the phone, Ye Ming's voice was a little smiling: "That's right, in a certain aerospace project, we have made a unified orbit, prediction and modeling of various planets, dwarf planets, and massive asteroids in the current solar system...... It was found to match the description of a previous paper on gravitational anomalies. ”

Li Lei took a deep breath, his brain began to spin rapidly, and he immediately nodded: "Hmm!" Physical Review Letters paper I have an image of a TNO gravitational anomaly, predicting that there are massive objects in the outer solar system that have not yet been discovered. ”

"Yes, so after modeling, I found that the position of FAST is right opposite the star field, see if you can do a favor, adjust the orientation of FAST a little, first aim at a star numbered FA8798-5452 to collect data, and then adjust the orientation every hour, the specific angle I sent through Aita, who authorized you."

With Ye Ming's voice on the phone, Li Lei also saw that the Aita terminal on his computer automatically popped out of the dialog box.

His heartbeat began to beat violently at this moment!

As an astronomer, he instantly understood Ye Ming's intentions.

——This is to hope that the Sky Eye will track and collect the deep space electromagnetic signals of a certain trajectory, and analyze whether there are undiscovered massive celestial bodies interfering or interfering!

Again I think of the hypothesis of this unknown celestial body in the astronomical community......

If it's an undiscovered planet, forget it, if it's really a black hole......

Li Lei instantly clenched his fists!

"Okay! Right away! ”

"Well, thank you in advance, because the window period is a bit short, so I have to call you first. You tell me what cooperation procedures are needed in the future, and I will make up for it. ”

"It's okay, it's okay, you just need a word, who doesn't dare to cooperate......"

Hanging up the phone and looking at the two people next to him, he laughed out loud!

"Let's go!"

Provincial delivery, after Ye Ming hung up the phone, he called Director Niu again.

After connecting, he told Director Niu that he wanted to use FAST, and by the way, he also told the other party that he didn't like to change partners.

On the phone, Director Niu's voice was a little surprised: "Why did you suddenly think of using FAST?" ”

Ye Ming laughed: "Then I'll go to Lao Mei and use Harper or Weber?" ”

“…… You're in the dark, aren't you? ”

"If it's not black, they will let me use it......" Ye Ming laughed and said: "Don't talk nonsense, I want to use it anyway, and that Li Lei ...... Just let him be in charge. ”

This Li Lei is an associate researcher after a doctorate, and judging from his previous work, he has also been patrolling the target sky, and many of the data that Ye Ming got are from his subject.

In addition, I received this call from myself on the holiday, which means that the two are destined.

Since there is fate, there is no need to make any more messy things.

"No problem, but you'll have to tell me what this is."

"How can I tell you? I said it could be a wandering black hole in the solar system? ”

Ye Ming heard a gasp from the other side of the phone.

Lao Niu's performance made Ye Ming very satisfied - it was obvious that Lao Niu still had a minimum of scientific literacy.

If a wandering black hole is really discovered in the solar system, then it is appropriate, and the Nobel Prize will definitely not be able to run away - this is not a matter of discovery, but of verification!

Now black holes are confirmed celestial bodies, but "small mass" and "wandering" black holes have always been hypotheses, and they really have to be proven...... That would mean that the model of the cosmic bodies would be a great refinement.

"Really?"

"Director Niu, at first glance, you are not engaged in scientific research." Ye Ming joked with a smile.

“……”

……

Hanging up the phone, Ye Ming exhaled softly.

Then he looked at Lacquer and Ink, who were sitting across from him.

Qi and Mo also looked at him, with a smile on their faces, in short, it was a little strange.

"It's a pity that you're not studying astronomy." Ye Ming said with a smile: "Otherwise, you can take at least two top issues." ”

"It's not uncommon!" Lacquer and ink waved their hands: "Tomorrow's developer conference, will you be there by yourself, or will you ......?"

Urushi and Mo glanced at Ita, who was sitting quietly next to him.

Ye Ming groaned.

At this ITA Developer Conference, the people who came were all well-known game companies and Internet companies, whether it was a goose farm, a pig farm or Ali, all of them were in place, and in terms of the candidates sent, there were many president-level executives of the company.

It can be said that ...... The face is still sufficient.

It stands to reason that Ye Ming, the CTO, should officially come forward.

But sometimes I can't help myself when I think about it......

"Ita should go, and then she will cooperate with you."

Qi and Mo took a breath softly, and their faces turned a little red from excitement: "Then really I'll go?" ”

"Well, you've been preparing all the time anyway, and there's no one in the company who is more powerful than you in your interactions with Aita." Ye Ming looked at the lacquer and ink, and a smile appeared on the corner of his mouth: "Go boldly, that is, to put a fork, so that they can see what advanced productive forces are." ”
