I Don’t Want to Win Lying Down

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

but...

ten minutes later,

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

...

...

...

what is happening?

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 gamma-ray bursts are a kind of strong light burst event, which can be said to be a kind of light itself. Logically speaking, the two should be at the same time. Arrive, why is there a gap of 1.7 seconds?

Faced with this problem,

The three quickly gave the answer. The first possibility is that gravitational waves can be detected by detectors without waiting for two neutron stars to collide. When the two neutron stars revolve rapidly, they can stimulate powerful space-time ripples ', according to calculations, it shows that the speed of revolving around each other reaches twelve circles per second.

Another possibility is that the propagation of light is greatly affected by matter in the universe. After all, the universe is not a true vacuum. Stars, nebulae, dust, and dark matter all have an impact on light, but have a weaker impact on gravitational waves.

The gravitational wave arrived 1.7 seconds earlier than the gamma ray burst, so it is not worthy of attention. It is the fact that it can appear.

After another ten minutes,

finally,

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

thanks everyone.

How about... how about we go for supper? Brother Chuanxiao asked: Beer and skewers, the more you eat, the more energetic you are. I haven't eaten skewers for a long time.

Can!

I don't care. Dong Yu shrugged, and said to Brother Chuan Xiao: Brother Chuan Xiao...Aren't you planning to go home today?

I won't go back so late,

It can affect other people in the family. Brother Chuan Xiao said: Stop dawdling, you two, hurry up and have a barbecue with me, I remember that you two can still drink.

at the same time,

Xu Mang was lying on the bed with a violent airport in his arms. He tried to close his eyes to sleep, but found that he couldn't fall asleep. No matter how hard he tried, his mind was full of gravitational waves.

found it...

It took half a year to finally find it.

Sudden,

The phone rang, which was the ringtone that Xu Mang had set separately for the email.

Taking the phone carefully, Xu Mang took a look at the contents. It was the data sent by brother Chuan Xiao. Through the temporary preview of the phone, Xu Mang took a look at the contents. It was the gravitational force recorded within a hundred seconds. Wave frequency changes.

Getting to work... Try to publish this discovery tomorrow morning!

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

first,

To prove that the recorded data is from the neutron star merger event of NGC 4994, in fact, this step is not very difficult, the gravitational wave signal is analyzed through the chirped mass, so as to obtain the best variable about the measured mass.

The chirped mass of NGC 4994 is between 1.186 and 1.192 solar masses, which basically matches.

Of course, this was just the beginning. After Xu Mang began to explore in depth, he discovered that through the combination of data from other observatories, this key combination gave another way to measure the expansion rate of the universe.

At the same time, through the data of electromagnetic phenomena, the host galaxy can be identified, and the physical behavior of the matter emitted by the merger event can also be studied, such as exploring the cause of relativistic jets.

At this time,

Xu Mang thought of the two black hole predictions he had completed, the swaying accretion disk and the swaying jet. The merging time just solved some unsolved problems in the swaying jet, and at the same time further affirmed the physics of the swaying jet. nature.

It's no accident,

It is a normal state in the universe.

Oh...fuck it! Xu Mang didn't dare to study any further. This piece of relativity is the last piece of the puzzle, which breaks too many theories that everyone insists on. It rejects the theory of dark matter simulation and limits gravity at the same time. The difference in velocity between waves and electromagnetic waves.

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

in,

What shocked Xu Mang the most was that gravitational waves seemed to be able to resolve the debate over the Hubble constant. Gravitational waves might eventually support one value of the Hubble constant rather than another, but might determine the third value of the Hubble constant. a new value.

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

...

the next day,

Joint Laboratory for Gravitational Wave Detection,

Professor Luo came to his office early, and today is still the same as usual, advancing slowly in confusion, trying to clear up all the problems at hand, but...Professor Luo understands that in the next six months, there may 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 make mistakes and making mistakes, it is better to take it slowly, solve every detail problem, and improve the theory step by step.

After making himself a cup of instant coffee, Professor Luo turned on the computer. Yesterday’s neutron star merger event became the main news today, and NASA became the protagonist of this event. According to this merger event, they gave short-lived gamma rays Violence explained.

Since 1990, the astronomical community has generally believed that short-lived gamma-ray bursts come from neutron star mergers, but there is no data to prove it. However, this merger event proves that any short-lived gamma-ray bursts originate from neutron star mergers.

The second is the European Space Agency ESA, which is the second protagonist of this neutron star merger event. They confirmed the existence of kilonovae. In detail... kilonova is an astronomical phenomenon caused by neutron star mergers.

I searched for a long time,

Professor Luo didn't see any research reports published by Hua Guo, and felt very emotional for a while.

for a long time,

Professor Luo's mentality returned to normal, and he started his day's work. It happened that the middle-aged man from yesterday walked in. He said to Professor Luo, Professor Luo... have you followed the news this morning?

Um!

This time the neutron star merger event has caused quite a stir in the astronomy world. Professor Luo said with emotion: Unfortunately... there is no shadow of us.

Actually...we have also recorded the relevant data, but there is a lack of comparison of the relevant data. The middle-aged man surnamed Dong sighed: But... to be able to experience this merger incident in person is also considered a death. No regrets.

Don't be so exaggerated. Professor Luo said with a smile: When we solve the gravitational wave, you can die without regret.

The middle-aged man surnamed Dong said with a wry smile: Professor Luo...to tell you the truth, many people in the team...are not confident enough, and now even Professor Xu's team has given up, resulting in many Started to wonder what I was doing.

Professor Luo sighed: Overcome any difficulties.

Farewell Professor Luo,

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

turn on computer,

This middle-aged man came to the Princeton Astrophysics Association. He didn't pay much attention to this association before, until Xu Mang became an official member of this association and published many heavyweight research reports on it. Heart.

The moment the computer page jumped over, suddenly... the middle-aged man was stunned, his breathing began to become rapid, and the consciousness of his brain was gradually emptied...

this...

Could it be true?

In the eyes of this middle-aged man, he saw a title, NGC 4994 galaxy neutron star merger event, the existence of gravitational waves was detected for the first time, the author - Xu Mang.

God!

What is the situation?

How did Professor Xu...how did he publish such an article all of a sudden?

Didn't he quit?

Isn't he working on quantum computers?

Why did he come back all of a sudden?

All kinds of questions filled the middle-aged man's head, which made him feel a little dizzy for a while. He glanced at the publication date and calculated it based on the time difference... It was just published in five minutes!

no no no no no...

I must be hallucinating!

The middle-aged man twisted his arm severely, and the pain swept through his body instantly. This time he realized that he was in the real world, not in a dream.

Trying to stabilize his thoughts, this middle-aged man realized that the first half of the title...NGC 4994 galaxy neutron star merger event, Professor Xu actually used yesterday's neutron star merger to prove gravitational waves?

He held the mouse tightly with trembling hands, and then clicked in. In just a few seconds, the middle-aged man stopped talking... He saw the frequency change after the merger of neutron stars, from tens of hertz to A few hundred hertz, you know that this is the frequency of gravitational waves.

Immediately afterwards,

He saw another strong evidence, analyzing the gravitational wave signal through the chirped mass, basically consistent with the observation data of other observatories.

So far,

It was only then that the middle-aged man discovered that Xu Mang hadn't withdrawn from gravitational wave detection as everyone thought, but was waiting for an opportunity, waiting for the neutron star merger event in the NGC 4994 galaxy.

He... cheated the whole world!

I...

Professor Xu!

It's a pity that I trust you so much...you actually played 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 of this had nothing to do with Xu Mang, it was because everyone was sitting there. guessing.

Unfortunately,

Everyone guessed wrong, they never left.

Sudden,

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

Brother Dong?

Why are you in such a hurry? A young researcher met a middle-aged man approaching him and asked with a smile, Could it be that the house is on fire?

The whole world is on fire!

leave a word,

The middle-aged man walked away with hurried steps without looking back.

...

What's the matter?
