I Don’t Want to Win Lying Down

Xu Mang's stay in the capital was quite short. He just handed in a few reports, then arranged specific work matters for Li Siyao and the others, and then returned directly to Shanghai. For now... there is no need to use this for the time being. super device.

Li Siyao and the others were doing routine maintenance, and they still kept the quantum computer in top condition.

Back to the magic capital,

Xu Mang hurried to the gravitational wave detection laboratory. The merger event was about to break out the day after tomorrow. To be precise, in the second half of the night tomorrow, the world's astronomical organizations would look at it, and he couldn't miss it.

How about it?

There shouldn't be any problems, right? Xu Mang stood beside the equipment and asked Brother Chuan Xiao beside him, Have you tried it?

Tried.

It's perfect. Brother Chuan Xiao said, Just wait for the big event you mentioned to break out.

oh...

What's the situation in Europe? Xu Mang asked curiously, How's their progress?

Brother Chuan Xiao shook his head, and said helplessly: I don't know yet...according to the current news, they are still in the stage of research and development of detection equipment, but...the joint detection team has been making big moves recently.

Big move?

What big move? Xu Mang asked in a daze, Why didn't I know?

Because it was covered by your news. Brother Chuan smiled and said, I saw reports about them by accident. At present...they have made a major breakthrough, and they have focused their attention on black holes. above.

Xu Mang froze for a moment. Black holes can indeed detect gravitational waves, but...according to calculations, it can be found that the energy released by them cannot be detected at all, not even with their own laser interference instruments. Equipment to perform more by oneself?

this...

Is this a joke? Xu Mang frowned, and said seriously, They invented more accurate equipment than ours?

I heard that it is a cylinder made of a magical special material. When gravitational waves pass through the cylinder, the gravitational wave will force the cylinder to stretch and compress in different directions. Chuan Xiaoxiong said: Weak pressure is generated inside the cylinder. ,

And through the precise piezoelectric sensor, this pressure change can be sensitively measured.

If the frequency of the gravitational wave coincides with the characteristic frequency of the cylinder itself, it will cause resonance, so that much weaker signals can be measured. Chuan Xiaoxiong said: Isn't it amazing?

Xu Mang froze for a moment, then said in confusion, How is it possible... Where did you get the news from?

hearsay.

A buddy told me. Brother Chuan smiled wryly and said, Don't tell me...in fact, the news is quite accurate. Tsingda University has developed a super-sensitive material, which probably has something to do with it.

Xu Mang was silent, then returned to his office, searched for relevant reports of the gravitational wave joint detection team, and found some clues. The ultra-sensitive material developed by Tsingda University was successfully developed two months ago. Matched.

but...

According to Xu Mang's simulation of the three-dimensional situation on the software, he found a problem... If the gravitational wave passes by will cause the current scene, then the scale of these changes should be very, very small. No material can have such an effect.

this...

It's impossible!

And what about noise interference?

Looking at the three computer simulations, Xu Mang fell into a daze for a while, and finally judged that the brand-new detection method mentioned by Brother Chuan Xiao was a friend of his who was talking nonsense. After all, this is a team composed of many experts. It is possible to make such a low-level mistake.

at the same time,

At the Joint Laboratory for the Detection of Gravitational Waves,

As the leader of the team, Professor Luo is leading his members to solve a problem. Although the project has been established for about half a year, it has not achieved anything. Xu Mang, who is also a competitor, Got an amazing achievement.

So far,

Many people have some frustration, but it also brings some good news.

At least Xu Mang had given up on this research topic.

Pay attention here.

There must be no mistakes. Professor Luo said solemnly: The sound interference of the earthquake is the most direct. We must cut off all external interference.

moment,

Professor Luo returned to his office. Before the chair was warmed up, a middle-aged man walked in.

Professor Luo?

In the middle of tomorrow night, there will be a neutron star merger event in the galaxy NGC 4994. Astronomical institutions all over the world are focusing on it. Shall we join in the fun? Horse ray burst?

Can.

Just make an announcement, as long as someone is willing to stay. Professor Luo has no objection to this. Anyway, the progress of the entire project is very slow. It's better to find other interesting things to do to increase the enthusiasm of the members.

good!

I'll do it now.

words fall,

The middle-aged man left the office directly, not to mention... There are many people who are willing to stay and appreciate this cosmic spectacle.

The time came to 20:07 the next day,

This middle-aged man, with many members, is waiting for the merger event of NGC 4994. In fact, this event has already happened. The light has not yet reached the earth, and the impression seen in the future is only left by the past. images only.

Is the gamma-ray burst detection instrument ready? the middle-aged man asked.

I have already connected to the database of the XXX International Astronomical Observatory, and I will be able to obtain relevant data at that time. A young researcher said: Brother Dong...Professor Xu really quit the gravitational wave detection project?

I don't know...

But I discussed it with Professor Luo, and I think there is a high probability that I will quit. The middle-aged man surnamed Dong said: From his research results in the past six months, we can see that he has already started working on the gravitational wave project. Transferred.

Faced with this answer,

Many people showed a hint of disappointment. Xu Mang's status among these people is very high. Now that this top scientist has withdrawn from this research project, does it mean that his mission to explore gravitational waves is currently impossible?

Brother Dong...

Could it be that Professor Xu thinks...with current scientific methods, gravitational waves cannot be detected? The researcher said seriously, Even his laser interference instrument can't.

about this point,

The middle-aged man surnamed Dong shook his head, and said seriously: It shouldn't be the case, Xu Mang didn't want to spend too much time on this research topic. After all, there are too many problems left for him. For a project, It is obviously not worth it to delay more projects.”

However,

Faced with the explanation of the middle-aged man surnamed Dong, many people expressed dissatisfaction.

soon,

Everyone stayed up until the middle of the night, and suddenly one by one felt as if they had been beaten with chicken blood, and a spectacle in the universe was about to happen in ten minutes. Everyone's face was full of anticipation, looking forward to this neutron star merger event, which can bring Brand new discovery.

exploded!

It's starting to explode! A researcher looked at the data on the screen and a flash of light on the image, and exclaimed excitedly: My God... this... this is simply amazing!

Previously,

According to the calculations of the International Gamma-ray Astrophysics Laboratory, the signal of this gamma-ray burst is very weak. Although NGC 4994 is not very far away from the earth, the material jet generated by the merger process is not directly ejected to the earth, but is in contact with the earth. The line of sight is at an angle of thirty degrees.

But that's enough,

Because at the same time, Xu Mang, who was far away in the magic city, was also monitoring gamma ray bursts and detecting gravitational waves at the same time.

Yes!

Professor Xu, the frequency has suddenly increased from 24 Hz to several hundred Hz! Standing in front of the monitor, Zhang Yapeng shouted excitedly to Xu Mang, This...does this mean that we have succeeded?

...

When this merger is over, let's have a look at the complete data. Xu Mang said indifferently.

a full hundred seconds,

The laser interference instrument worked for a hundred seconds, and then returned to the pre-set frequency of 24 Hz.

this...

That's it!

It's over before it even started?

Wang Ai and the others were a little disappointed. They had prepared for half a year just for this moment, but the result was not as earth-shattering as they had imagined. They just sat in the office, looked at a bunch of display screens, watched the numbers keep beating, and then let They slowly return to the starting point.

slightly disappointed...

It feels like it's over before it even begins.

Professor Xu?

This... is this the end? Zhang Yapeng said helplessly, Why don't we have any sense of joy?

Detection is only part of success, and subsequent proof is the key. Xu Mang shrugged and said calmly, And it's not just our own proof, but we also need others to help us prove it.

Hearing Xu Mang's call, many people showed a trace of doubt.

Xu Mang smiled, and Brother Okikawa said, Help me collect the complete data immediately...and send it to my email.

...

on the way back,

Although there weren't many vehicles in Modu in the middle of the night, Xu Mang drove very slowly. In the laboratory before, he realized that he had made a serious mistake and imagined the problem too simply. Although gravitational waves were detected, the follow-up work But there are as many as a cow's hair.

prove?

Xu Mang didn't intend to prove too much. In short, he wanted to know whether this was a gravitational wave or not. He had to find the answer by himself. The most important task at present was to try to rule out some alternative theories based on the collected relevant data.

For example, general relativity cannot explain the accelerated expansion of the universe. So far, many alternative theories have tried to explain the accelerated expansion of the universe with the concept of dark energy. Xu Mang wanted to exclude some unqualified theories.

This is a complicated job, and it is also a thankless job. He can even think of some scientists who support those theories attacking him.

but...

Truth cannot be hidden in falsehood, there must always be someone who stands up and announces the truth to the world.

Xu Mang sighed, and said helplessly to himself.

I've already married Yang Xiaoman...what else do I have to be afraid of?

Just do it!
