Chapter 623: Just do it!

Xu Mang stayed in the capital for a short period of time. He just handed in a few reports, and then arranged specific work matters for Li Siyao and he went back to the magic city. For now... there is no need to use this for now. A super device.
However, Li Siyao is carrying out daily maintenance work and still keeps this quantum computer in its best condition.
Back to the magic city,
Xu Mang hurried to the gravitational wave detection laboratory, the day after tomorrow the merger event is about to erupt. To be precise, in the second half of tomorrow, astronomical organizations all over the world will look at it, and he cannot miss it.
"how about it?"
"There should be no problems, right?" Xu Mang stood by the equipment and asked to Brother Chuan Xiao next to him: "Have you tried it?"
"Try it."
"Very 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 is 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 developing detection equipment, but...the joint detection team has been making big moves recently."
"Big move?"
"What big move?" Xu Mang asked with a dazed expression: "Why don't I know?"
"Because it is covered by your news." Brother Chuan Xiao smiled: "I saw a report about them by accident. At present...they have made a major breakthrough, and they focused on the black hole. Above."
Xu Mang was stunned. The black hole can indeed detect gravitational waves, but... According to calculations, it can be found that the energy released by it is not detectable at all, even with their own laser interferometer. Could it be...they found a comparison More equipment to carry on by oneself?
"This..."
"Is this a joke?" Xu Mang frowned, and said solemnly: "They invented a more precise device than us?"
"I heard that it is a cylinder made of a magical special material. When a gravitational wave passes through the cylinder, the gravitational wave will force the cylinder to continuously stretch and compress in different directions." Brother Chuan Xiao said: "There is a weak pressure inside the cylinder. , And through a precise piezoelectric sensor, this pressure change can be measured sensitively."
"If the frequency of the gravitational wave coincides with the characteristic frequency of the cylinder itself, it will cause resonance, so that a much weaker signal can be measured." Brother Chuan Xiao said: "Is it amazing?"
Xu Mang was stunned for a moment, and said in a daze, "How is it possible...where did you get the news?"
"hearsay."
"A buddy told me." Brother Chuan Xiao smiled bitterly: "Don't tell me... Actually, this news is quite accurate. The National Tsing Hua University has developed an ultra-sensitive material, which is probably related."
Xu Mang was silent, and then returned to his office to search for related reports of the gravitational wave joint detection team, and found some clues. The ultra-sensitive material of Tsing Hua University was successfully developed two months ago. It's a coincidence.
but...
According to Xu Mang's simulation of the three-dimensional situation on the software, a problem was found... If gravitational waves pass by will cause the current scene, then the scale of these changes should be very, very small. At present, any kind in this world No material can have such an effect.
This...
It's impossible!
What should I do if there is noise interference?
Xu Mang looked at the three computational simulations and fell into confusion for a while, and finally judged that the new detection method mentioned by Brother Chuan Xiao was nonsense by a friend of his. After all, this is a team composed of many experts. May make such low-level mistakes.
at the same time,
In the Joint Laboratory of Gravitational Wave Detection,
As the leader of this team, Professor Luo is leading his members to overcome a problem. Although this project has been around for half a year since its establishment, there has been no gain. And Xu Mang, who is also a competitor, Achieved an amazing achievement.
So far,
Many people are a little frustrated, but it also brings some good news.
At least Xu Mang has given up on this research topic.
"Pay attention here."
"Don't make any 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. The chair was still warm, and a middle-aged man walked in.
"Professor Luo?"
"At midnight tomorrow, there will be a neutron star merger in the galaxy of NGC4994. Astronomical institutions all over the world are looking at it. Should we join in the fun?" The middle-aged man laughed and said, "Let’s study gamma. Ray burst?"
"can."
"Send an announcement, and someone is willing to stay." Professor Luo has no objection to this. Anyway, the progress of the entire project is very slow. It is better to find other interesting things to do to increase the enthusiasm of the members.
"it is good!"
"I will do it now."
Words fall,
The middle-aged man left the office directly, let alone... many people are willing to stay and appreciate the wonders of the universe this time.
Time came to 20:07 the next day,
This middle-aged man, with many members, is waiting for the merger event of NGC4994. In fact, this event has already happened. At present, the light has not reached the earth yet, and the impressions he sees in the future are only from the past. Image only.
"Are the gamma-ray burst detection equipment ready?" the middle-aged man asked.
"It has been connected to the database of the XXX International Astronomical Observatory, and relevant data will be available by then." A young researcher said: "Dong Ge...Professor Xu really withdrew from the gravitational wave detection project?"
"Not sure..."
"But I discussed with Professor Luo and felt that there was a high probability that he would withdraw." The middle-aged man surnamed Dong said: "From the results of his research in the past six months, we can see that in fact, he has already learned from the gravitational wave project. Transferred."
Faced with this answer,
Many people showed a look of disappointment. Xu Mang's status in these people is very high. Now that the top scientist withdraws from this research project, does it mean that his mission to explore gravitational waves is currently impossible?
"Brother Dong..."
"Does Professor Xu think that...with current scientific methods, gravitational waves cannot be detected?" The researcher said seriously, "Even his laser interferometers are not good."
about this point,
The middle-aged man surnamed Dong shook his head and said solemnly: "This should not be the case. Xu Mang does not want to spend too much time on this research topic. After all, there are too many questions left for him. For one project, It is obviously not worth it to delay more projects."
however,
Facing the explanation of the middle-aged man surnamed Dong, many people expressed dissatisfaction.
quickly,
Everyone stayed up in the middle of the night, and suddenly one by one, like a chicken blood, the wonders of the universe will happen in ten minutes. Everyone’s face is full of expectation, looking forward to this neutron star merger event, which can bring A new discovery.
"exploded!"
"It's starting to explode!" A researcher looked at the data on the screen and a shining spot on the image, and exclaimed excitedly: "Oh my god... this... this is amazing!"
Before,
According to calculations by the International Gamma-ray Astrophysics Laboratory, the signal of this gamma-ray burst is very weak. Although NGC4994 is not very far from the earth, the material jets generated during the merger process are not directly directed toward the earth, but are in line of sight. It is an angle of thirty degrees.
But these are enough,
Because at the same time, Xu Mang, who is far away in the magic capital, is also monitoring gamma-ray bursts and is also detecting gravitational waves.
"Yes!"
"Professor Xu, the frequency started from 24 Hz and suddenly increased to a few hundred Hz!" Zhang Yapeng stood in front of the monitor and exclaimed at Xu Mang excitedly: "This... does this mean we succeeded?"
"..."
"When this merger is over, let's take a look at the complete data." Xu Mang said calmly.
Exactly one hundred seconds,
The laser interferometer worked for 100 seconds, and then it returned to the preset frequency of 24 Hz.
This...
Is this done?
Is it over before it starts?
Wang Ai and a few people were disappointed. They prepared for half a year for this moment. However, the result was not as earth-shattering as they had imagined. They just sat in the office, looking at a bunch of display screens, watching the numbers beating constantly, and then let They slowly return to the starting point.
Slightly disappointed...
It feels like it has not yet started, it is over.
"Professor Xu?"
"This...this is the end?" Zhang Yapeng said helplessly: "Why don't we have any sense of joy?"
"Detection is only part of the success, and follow-up 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 Chongchuan Xiao said: "I will collect complete data for me right away... and send it to my mailbox."
...
On the way back,
Although there are not many vehicles 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 assumed the problem too simplistically. Although gravitational waves were detected, follow-up work It's just like a feather.
prove?
Xu Mang does not intend to prove too much. UU Reading www.uukānshu.com wants to know if this is a gravitational wave, and find the answer by himself. The most important task at present is to try to exclude certain things based on the collected data. Instead of theory.
For example, general relativity cannot give an explanation for 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 wants to eliminate some unqualified theories.
This is a complicated job, and it is also a thankless job. He can even think of the attacks on himself by certain scientists who support those theories.
but...
Truth cannot be hidden from falsehood. There is always someone who should stand up and announce the truth to the world.
Xu Mang sighed and said to himself helplessly.
"I have married Yang Xiaoman as his wife... What else do I have to fear?"
"Just do it!"
