Brother Chuan Xiao, Dong Yu and Zhang Yapeng did not sleep, but began to sort out the data overnight, and for the three of them, they did not feel any excitement when they recorded gravitational waves, but a little sense of loss.

But...

Ten minutes later,

The trio were surprised to find that the gravitational waves appeared 1.7 seconds earlier than the gamma-ray burst.

“...”

“...”

“...”

What's going on here?

The three of them are in a completely confused stage, Einstein once predicted that the speed of gravitational waves is the speed of light, and the gamma-ray burst is a strong light burst event, which can be said to be a kind of light itself, according to the logic that the two should arrive at the same time, why is there a difference of 1.7 seconds?

Faced with this problem,

The first possibility is that gravitational waves can be detected by the probe without waiting for two neutron stars to collide, and when the two neutron stars orbit rapidly, they can induce powerful 'space-time ripples', and according to calculations, the speed of orbiting each other reaches 12 revolutions per second.

Another possibility is that the propagation of light is greatly affected by the matter in the universe, after all, the universe is not a real vacuum, stars, nebulae, dust, dark matter, will have an impact on light, and the influence on gravitational waves is weak.

The gravitational wave, which is 1.7 seconds earlier than the gamma-ray burst, is not worth paying attention to, but its presence is the point.

After another ten minutes or so,

finally

The three of them sorted out all the data, and then Brother Chuan Xiao sent the data to Xu Mang's mailbox.

"Thank you all for your hard work. ”

"Or... How about we go for supper?" Brother Chuan Xiao asked, "Beer and skewers, the more you eat, the more energetic you become, I haven't eaten skewers for a long time." ”

"Yes!"

"I don't care. Dong Yu shrugged his shoulders and said to Brother Chuanxiao: "Brother Chuanxiao... Are you not going home today?"

"If you don't go back so late, it will affect the rest of the family. Brother Chuan Xiao said: "Don't rub it off, you two hurry up and go to eat barbecue with me, I remember that the two of you can still have a lot of alcohol." ”

meanwhile

Xu Mang was lying on the bed, holding a violent airfield in his arms, he tried to close his eyes and sleep, but he found that he couldn't sleep, no matter how hard he tried, his mind was full of gravitational waves.

Got it...

It took half a year to finally find it.

suddenly

The phone ringtones, which is the ringtone that Xu Mang sets separately for the email.

Carefully got the mobile phone, Xu Mang glanced at the content inside, it was the data sent by Brother Chuan Xiao, through the temporary preview of the mobile phone, Xu Mang glanced at the content inside, this is the recorded gravitational wave frequency change in a hundred seconds.

It's time to get to work... Aim to announce this discovery tomorrow morning!

Secretly letting go of Yang Xiaoman, Xu Mang put on his clothes and pants, carefully slipped out of the bedroom, and began his work.

First of all

Proving that the recorded data is a neutron star merger event from NGC 4994 is not very difficult to analyze the gravitational wave signal by chirping mass to obtain the best variable about the quality of the measurement.

The chirped mass of NGC 4994 is 1.186 to 1.192 solar masses, which is basically the same.

Of course, this is only the beginning, and after Xu Mang began to explore further, he found that through the combination of data from other observatories, this crucial combination gave another way to measure the expansion rate of the universe.

At the same time, through electromagnetic data, it is possible to identify host galaxies, and to study the physical behavior of the matter emitted by merger events, such as exploring the causes of relativistic jets.

Then

Xu Mang thought of the two black hole predictions he had completed, the swinging accretion disk and the swinging jet, and the merging time just solved some unsolved problems in the swinging jet, and further affirmed the physical properties of the swinging jet.

This is no accident,

It's a norm in the universe.

"Oops... it!" Xu Mang didn't dare to study any further, this piece of the theory of relativity has the most piece of the puzzle, breaking too many theories that everyone insists on, it refutes the theory of dark matter simulation, and at the same time limits the difference in wave velocity between gravitational waves and electromagnetic waves.

Any new alternative theory must assume that gravitational waves and electromagnetic waves travel at the same speed.

thereinto

What shocked Xu the most was that gravitational waves seemed to solve the Hubble constant controversy, and gravitational waves might eventually support one value of the Hubble constant instead of another, but might decide a third new value of the Hubble constant.

"It's kind of interesting!" Xu Mang showed a smile, and then he turned on the beast mode, and he had to solve all the problems before dawn!

...

Following

Joint Laboratory for Gravitational Wave Detection,

Professor Luo came to his office early, and today, as usual, he slowly moved forward in confusion, trying to clear all the problems at hand, but... Professor Luo understands that in the next six months, I am afraid there will still be no progress.

In the past,

He may be rushed to death, but now he is calm, anyway, there are no competitors in the country, instead of rushing to the schedule and leading to mistakes, it is better to take his time, solve every detail problem, and improve this theory step by step.

Having made himself a cup of instant coffee, Professor Luo turned on the computer, and yesterday's neutron star merger became the main news of the day, in which NASA became the protagonist of this event, and they explained the brief gamma-ray burst based on this merger event.

Since the 1990s, the astronomical community has believed that the transient gamma-ray burst is due to neutron star mergers, but there is no data to prove this, but this merger event proves that any transient gamma-ray bursts are due to neutron star mergers.

The second is the European Space Agency ESA, which is the second protagonist of this neutron star merger event, and they confirmed the existence of a thousand novae. A kilonova is an astronomical phenomenon created by the merger of neutron stars.

After looking for a long time,

Professor Luo did not see any research reports published by Huaguo, and he was very emotional for a while.

Long

Professor Luo's mentality returned to normal and started the day's work, when the middle-aged man from yesterday walked in and said to Professor Luo: "Professor Luo... Did you follow the news this morning?"

"Hmm!"

"This neutron star merger incident has caused a lot of waves in the astronomical community. Professor Luo sighed: "It's a pity... There is no shadow of us. ”

"Actually... We also recorded the relevant data, but there was a lack of comparison. The middle-aged man surnamed Dong sighed: "But... Being able to experience this merger event can be regarded as a death without regrets. ”

"Don't be so exaggerated. Professor Luo smiled: "When we solve the gravitational waves, you can die without regrets." ”

The middle-aged man surnamed Dong smiled bitterly: "Professor Luo... I'll be honest with you, a lot of people on the team... They are all lacking in confidence, and now even Professor Xu's team has given up, causing many people to start doubting what they are doing.

Professor Luo sighed: "If there are difficulties, overcome them." ”

Farewell to Professor Luo,

The middle-aged man surnamed Dong returned to his office, and at this moment... He suddenly thought of Xu Mang, and also realized his importance, with him and without him, the atmosphere of the whole team was completely different.

Turn on your computer,

This middle-aged man came to the Princeton Astrophysical Society, which he didn't pay much attention to before, until Xu Mang became an official member of this association, and published many heavyweight research reports on it, and this Princeton Astrophysical Society also kept it in mind.

The moment the computer page jumps past, and all of a sudden... The middle-aged man was stunned, his breathing began to be rapid, and the consciousness of his brain gradually emptied...

This...

Isn't that true?

In the eyes of this middle-aged man, he saw a title, "NGC 4994 Galaxy Neutron Star Merger Event, the First Detection of the Existence of Gravitational Waves", author - Xu Mang.

Oh, my God!

What's going on?

How did Professor Xu... How did such an article suddenly be published?

Didn't he quit?

Isn't he working on quantum computers?

Why did he suddenly come back?

All kinds of questions filled the middle-aged man's head, which made him feel a little dizzy for a while, and he glanced at the publication date and calculated according to the time difference... Five minutes money has just been published!

No, no, no, no...

I must be hallucinating!

The middle-aged man twisted his arm hard, and the pain swept through his body in an instant, and this time he realized that he was in the real world, not in a dream.

Struggling to hold his mind steady, the middle-aged man realized this time that the first half of the title... In the NGC 4994 galaxy neutron star merger event, Professor Xu actually used yesterday's neutron star merger to prove gravitational waves?

The trembling hand held the mouse tightly, and then clicked in, but in just a dozen seconds, the middle-aged man stopped talking... He saw the frequency change from tens of hertz to hundreds of hertz after the neutron star merged, and he knew that this was the frequency of gravitational waves.

Followed by

He saw another strong piece of evidence, the analysis of gravitational wave signals by chirping mass, which basically matched the observations of other observatories.

So far

The middle-aged man realized that Xu Mang had not withdrawn from gravitational wave detection as everyone thought, but was waiting for an opportunity to wait for the arrival of the neutron star merger event in the NGC 4994 galaxy.

He... Deceived the whole world!

"I..."

"Professor Xu!"

"It's a shame that I trust you so much... You actually play with my emotions!" The middle-aged man was so angry that he vomited blood, but he was very helpless in his heart, in fact, all this had nothing to do with Xu Mang, it was all a blind guess that everyone was sitting there and trying to.

Unfortunately,

Everyone guessed wrong, people never left.

suddenly

The middle-aged man hurriedly ran out of his office and went to Professor Luo.

"Brother Dong?"

"Why are you in such a hurry?" a young researcher asked with a smile when he met the oncoming middle-aged man, "Could it be that there is a fire in the house?"

"It's the whole world on fire!"

Drop a word,

The middle-aged man didn't look back, and left with hurried steps.

“...”

"What's going on?"

......
