From black technology to super engineering

Pingtan, 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 largest radio telescope in the world, after the fall of Arecibo, it is the only radio telescope with a diameter of more than 300 meters in the world. It is a well-deserved national heavyweight, and even the top observation tool in the entire astronomy community.

Especially for the observation of pulsars, in just a few years, it has discovered hundreds of pulsars, greatly filling the pulsar database.

The so-called pulsar refers to a neutron star that rotates at a high speed and continuously emits electromagnetic signals. It is generally believed that it is formed by a supernova explosion, but the new theoretical framework "accretion-induced collapse" also shows that supernova explosion is not the only way it is formed. .

Of course, the ability of FAST is far more than just "targeting" pulsars. Its ingenious adjustable angle design, super large reflector and high-sensitivity feed make it very good at observing the neutral hydrogen region.

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 give me two more candies next time?"

In the international cooperation base across the mountain from FAST, Li Lei held coffee that was bitterer than traditional Chinese medicine, with a constipated expression on his face: "Didn't you say that Italians like sweets, why are you the other way around?"

"Adding sugar is easy to gain weight."

Samuel held the coffee, leaned on the desk, and took a sip without changing his expression.

Their office is not big, just five or six positions. Besides the two postdoctoral fellows, there is also Samuel's Sita, and a postgraduate girl from Nantah University working here with her supervisor.

It was the weekend, and they were still in the office. On the one hand, they had no hard needs, and on the other hand, they also had to stare at the data of a new suspicious pulsar. Discovery is always exciting for astronomers.

The Sita was bought by Samuel, who came from Venice, a leather goods family, and a wealthy family. His father opened a factory in Wenzhou, and he applied for a Ph.D. in astronomy at the First University of Rome and came to FAST.

When he robbed Sita last time, everyone in the office "contributed" to him, so he kept his promise and made Sita a waiter in the office.

Li Lei is different from him. He comes from P University and has been working here for six years. Before that, he followed his mentor, but now he works alone. Although he has published a lot of papers, he always feels that they are not interesting enough.

If he is engaged in astronomy, he must be able to live with loneliness. Anyway, he has stayed in this corner for a few years, and his wife has no objection, so he is naturally happy to stay.

The two were chatting casually, and Chen Xiang, a junior sister from Nantah University, was holding a tablet to watch videos—they were located in the core area, and the mobile phone and wifi were not available—but it was no problem to set up a hidden hotspot indoors of.

After all, the signal of wifi, not to mention the mountains, even the walls are almost gone.

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

"That depends on whether the higher-ups are willing to spend money, and now we can't even run Aita's computing power." Li Lei glanced at his computer monitor as he spoke.

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

But as Jizhi Technology provides more and more services, their computing power distribution is becoming more and more limited. It is better that Aita has been equipped with quantum computers until now.

"Huh? Raise computing power?"

Li Lei immediately sat upright, seeing that the analysis progress was only 10% five minutes ago, and now it is directly completed, he immediately yelled: "Fuck, I really increased my computing power!"

The other two immediately stood behind him.

On the monitor, it shows that the data analysis has indeed been completed.

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

At this moment, the phone on the table rang suddenly, startling him.

After picking up the phone, Li Lei clicked on the report at the same time: "Hello, who is it?"

A young voice came from the phone: "Hi, is 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 smile came from the phone: "Well, it seems that we really don't know each other..."

"Wait." Li Lei was taken aback for a moment.

At this moment, the two people beside him also looked at him in shock.

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

Li Lei's heartbeat quickened instantly.

"Ye Ming...Is he Professor Ye Ming from the Provincial Jiaotong University?"

"Well, it's me, what's your name?"

"Ah... Hello, Professor Ye..." Li Lei stood up instantly, took a few breaths and suppressed his excitement, "My name is Li Lei, and I am an associate researcher at the FAST International Cooperation Laboratory."

"Hello, Mr. Li." On the phone, Ye Ming's voice was a little smiling: "It's like this. In a certain spaceflight project, we have done research on the current planets, dwarf planets, and massive asteroids in the solar system. A unified orbit and predictions and modeling ... found it fit the description of a previous paper on gravitational anomalies."

Li Lei took a deep breath, his mind began to turn quickly, and he nodded immediately: "Yes! I have an image of the paper in Physical Review Letters, and the TNO gravitational anomaly predicts that there are undiscovered massive celestial bodies in the outer solar system."

"Yes, so after modeling, I found that the position of FAST is just facing the star field. Can you do me a favor, adjust the orientation of FAST a little, and first align it with a star collection numbered FA8798-5452. data, and then adjust the orientation every hour, and I will send the specific angle through Aita who authorized you.”

Following Ye Ming's voice on the phone, Li Lei also saw it, and the Aita terminal on his computer automatically jumped out of the dialog box.

His heartbeat began to beat violently at this moment!

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

——It is hoped that the sky eye will track and collect the deep-space electromagnetic signals of a certain trajectory, and analyze whether there are undiscovered large-mass celestial bodies that are interfering or interfering!

Reminiscent of the hypothesis of this unknown celestial body in the astronomy community...

It’s fine if it’s an undiscovered planet, if it’s really a black hole…

Li Lei clenched his fist instantly!

"Okay! Now!"

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

"It's okay, it's okay, you only need one word, who would dare to cooperate..."

Hanging up the phone, looking at the two people beside him, he laughed out loud!

"Let's do it!"

Provincial post, 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 also told the other party that he didn't like changing 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?"

"...Are you hacking into it?"

"They will let me use it if they are not black..." Ye Ming laughed and said: "No nonsense, anyway, I want to use it, and that Li Lei... let him take care of it."

This Li Lei is a post-doctoral associate researcher. Judging from his previous work, he has been patrolling the target sky. Many of the data Ye Ming got were from his projects.

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

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

"No problem, but you have to tell me, what kind of result is this?"

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

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

Ye Ming was very satisfied with Lao Niu's performance—obviously, Lao Niu still had a minimum scientific literacy.

If a wandering black hole is really found in the solar system, then it is all right, the Nobel Prize will never escape-this is not a problem of discovery, but a problem of verification!

Now black holes have been proven celestial bodies, but "small mass" and "wandering" black holes have always been hypotheses. If it is really to be proved... that means that the model of cosmic celestial bodies will be greatly improved.

"real or fake?"

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

"..."

...

After hanging up the phone, Ye Ming exhaled softly.

Then, he looked at Paint and Ink sitting across from him.

Qi and Mo also looked at him, with a smile on their faces, which was a bit strange anyway.

"It's a pity, you don't study astronomy." Ye Ming said with a smile: "Otherwise you can get at least two top issues."

"It's not rare!" Qi and Mo waved their hands: "Tomorrow's developer conference, will you attend by yourself, or..."

Qi and Mo took a look at Ita who was sitting quietly next to him.

Ye Ming pondered.

This time ita developer conference, the people who came are all well-known game companies and Internet companies, whether it is a goose farm, a pig farm or Ali, they are all in place, and judging from the candidates sent, there are not many companies among them. president-level executives.

It can be said that...the face is still enough.

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

But when I think about myself, sometimes I can't hold it back...

"It's better to go with Ita, and then she will cooperate with you."

Qi and Mo took a light breath, and their face turned a little red because of excitement: "Then I'm really going?"

"Well, anyway, you have been preparing all the time, and no one in the company is better than you in the interaction with Aita." Ye Ming looked at Paint and Mo, with a smile on the corner of his mouth: "Go boldly, just pretend to be a fork , Let them see what advanced productivity is."
