Xu Mang's stay in the capital was quite short, he just handed in a few reports, and then arranged specific work matters for Li Siyao and the others, and returned directly to the magic capital. There is no need to use this super device just yet.

And Li Siyao and the others are carrying out daily maintenance work and still maintaining the best state of this quantum computer.

Back to the magic capital,

Xu Mang hurriedly went to the gravitational wave detection laboratory, and the day after tomorrow merger event was about to break out, to be precise, in the second half of the night, when the world's astronomical organizations would look at it, and he could not miss it.

"How?"

"There should be no problem, right?" Xu Mang stood on the edge of the equipment and asked Brother Chuan Xiao beside him, "Have you ever had a trial run?"

"Tried. ”

"It was perfect. Brother Chuan Xiao said: "Just wait for the big incident you said to break out." ”

"Oh..."

"What's going on in Europe?" Xu Mang asked curiously, "How is their progress?"

Brother Chuan Xiao shook his head and said helplessly: "I don't know for the time being... According to the current news, they are still in the stage of developing detection equipment, but... The joint detection team has been making big moves recently. ”

"Big move?"

"What big move?" Xu Mang asked with a confused expression, "Why don't I know?"

"Because I've been covered by your news. Brother Chuan Xiao smiled: "I saw a report about them by chance, so far... They had a major breakthrough, and they focused their eyes on the black hole. ”

Xu was stunned for a moment, black holes can indeed explore gravitational waves, but... According to the calculation, it can be found that the energy released by it is not detectable at all, even if it is its own laser interferometer can't, is it... Did they find a device that was more advanced than their own?

"This..."

"Is this a joke?" Xu Mang frowned and said solemnly, "They have invented a more accurate device than us?"

"I heard that it is a cylinder made of a magical special material, and when gravitational waves pass through the cylinder, the gravitational waves force the cylinder to constantly stretch and compress in different directions. Brother Chuan Xiao said: "A weak pressure is generated in the cylinder, and through the precision piezoelectric sensor, this pressure change can be measured sensitively. ”

"If the frequency of the gravitational wave happens to coincide with the eigenfrequency of the cylinder itself, it causes resonance, which makes it possible to measure much weaker signals. Brother Chuan Xiao said: "Isn't it amazing?"

Xu Mang was stunned for a moment, and said confusedly: "How is it possible... Where did you get the news?"

"Hearsay. ”

"It was a buddy who told me. Brother Chuan Xiao smiled bitterly: "Don't say it... In fact, this news is quite accurate, and Qingda has developed an ultra-sensitive material, which is estimated to have some relationship. ”

Xu Mang was silent, and then returned to his office, searching for relevant reports from the gravitational wave joint detection team, and found some clues, this ultra-sensitive material of Qingda was successfully developed two months ago, and this time coincided.

But...

According to Xu Mang's simulation of the three-dimensional situation on the software, a problem was found... If gravitational waves pass by and create such a scene, then the scale of these changes should be very, very small, and it is impossible for any material in the world to have such an effect at present.

This...

It's impossible!

And what about noise interference?

Xu Mang looked at the three simulations on the calculation, and fell into confusion for a while, and finally judged that the new detection method mentioned by Brother Chuan Xiao was nonsense from a friend of his, after all, this is a team composed of many experts, and it is impossible to make such a low-level mistake.

meanwhile

At the Joint Laboratory for Gravitational Wave Detection,

As the leader of this team, Professor Luo is leading his members to overcome a problem, although the project has been established for about half a year, but there is no gain, and Xu Mang, who is also a competitor, has achieved an amazing achievement.

So far

A lot of people are a little frustrated, but there is also some good news.

At least Xu Mang has 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, and we must cut off all external interference. ”

moment

Professor Luo returned to his office, and before the chair was hot, a middle-aged man walked in.

"Professor Luo?"

"Later tomorrow night, there will be a neutron star merger event in the galaxy of NGC 4994, and astronomical institutions around the world are focusing on it, should we join in the fun?"

"Yes. ”

"Just make an announcement, and someone will want to stay. Professor Luo has no opinion on this, anyway, the progress of the whole project is very slow, it is better to find other interesting things to do to improve the enthusiasm of the members.

"Good!"

"I'll do it. ”

Words fall,

The middle-aged man left the office directly, not to mention... There are many people who are willing to stay and enjoy the wonders of the universe this time.

The time came to 20:07 the next day,

This middle-aged man, with many members, waited for the merger of NGC 4994, in fact, this event had already happened, and the light had not yet reached the earth, and the impression seen in the future was only an image left by the past.

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

"I have connected to the database of the XXX International Observatory, and the relevant data will be available at that time. A young researcher said, "Brother Dong... Did 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 he will quit. The middle-aged man surnamed Dong said: "From his research results in the past six months, we can see that he has long since moved away from the gravitational wave project. ”

Faced with this answer,

Many people showed a look of disappointment, Xu Mang's status among these people is very high, and now 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?" said the researcher seriously, "not even his laser interferometer is fine." ”

On this point,

The middle-aged man surnamed Dong shook his head and said solemnly: "It shouldn't be the case, it's because Xu Mang doesn't want to spend too much time on this research topic, after all, there are too many problems left for him, and it is obviously not worth delaying more projects for the sake of one project." ”

however

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

soon

Everyone stayed up until the second half of the night, and suddenly one by one it was like being beaten with chicken blood, and there were still ten minutes before the wonders of the universe would happen, and everyone's face was full of anticipation, looking forward to this neutron star merger event, which could bring new discoveries.

"It's exploded!"

"It's starting to explode!" one researcher exclaimed, looking at the data on the screen and a flash of light on the image, "Oh my God... This... It's just amazing!"

Previously

According to calculations by the International Gamma-ray Astrophysics Laboratory, the gamma-ray burst signal is very weak, and although NGC 4994 is not very far from the Earth, the jet of material generated by the merging process is not directly sprayed at the Earth, but at an angle of 30 degrees to the Earth's line of sight.

But that's enough,

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

"There it is!"

"Professor Xu, the frequency started at twenty-four hertz and suddenly increased to several hundred hertz!" Zhang Yapeng stood in front of the monitor and shouted at Xu Mang excitedly: "This... Does that mean we've succeeded?"

“...”

"When this merger is over, let's see the full numbers. Xu Mang said indifferently.

A full hundred seconds,

The laser interferometer worked for a hundred seconds, and then returned to a pre-set frequency of twenty-four hertz.

This...

That's it?

It's over before it starts?

Wang Ai and the others were a little disappointed, and they had been preparing for half a year, just for this moment, but the result was not as earth-shattering as they imagined, just sitting in the office, looking at a bunch of displays, watching the numbers keep jumping, and then letting them slowly return to the starting point.

Slightly disappointed...

The feeling is over before it even begins.

"Professor Xu?"

"It's... This is the end?" Zhang Yapeng said helplessly: "Why don't we have any sense of joy?"

"Probing is only part of the success, subsequent proof is the key. Xu Mang shrugged his shoulders 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 on their faces.

Xu Mang smiled, and Brother Chong Chuan smiled and said, "Help me collect complete data immediately... Then send it to my mailbox. ”

...

On the way back,

Although there were not many vehicles in the middle of the night, Xu Mang drove very slowly, and before in the laboratory, he realized that he had made a serious mistake, and the problem was too simple, although gravitational waves were detected, the follow-up work was as much as a cow's hair.

Prove?

Xu Mang doesn't plan to prove too much, in short, he wants to know whether this is a gravitational wave or not, and find out the answer for himself, and the most important work at present is to try to rule out some alternative theories according to the relevant data collected.

For example, the general theory of relativity cannot explain the accelerated expansion of the universe, so many alternative theories have tried to explain the accelerated expansion of the universe with the concept of dark energy.

It's a complicated job, and it's a thankless job, and he can even think of some of the scientists who support those theories, attacking him.

But...

The truth cannot be hidden from falsehood, and someone must always stand up and make the truth known to the world.

Xu Mang sighed and said to himself helplessly.

"I married Yang Xiaoman as my wife... What else am I afraid of?"

"Just do it!"
