"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!"
......
Chapter 624 He Never Left (1/3)
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...
10 minutes later,
The trio were surprised to find that gravitational waves appeared [-] 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 [-] 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 two neutron stars revolve rapidly, they can stimulate powerful space-time ripples. According to calculations, the speed of revolving around each other has reached 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 [-] seconds earlier than the gamma ray burst, so it is not worth paying attention to. The key point is that the gravitational wave can appear.
After another ten minutes,
at last,
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 delicious 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 will affect the rest of the family." Brother Chuan Xiao said, "Stop dawdling, both of you, 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.
suddenly,
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 of all,
To prove that the recorded data is from the neutron star merger event of NGC 4994, in fact, this step is not very difficult, and the gravitational wave signal is analyzed through the chirped mass, so as to obtain the best variable for measuring the mass.
The chirped mass of NGC 4994 is between [-] and [-] 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 rooftops, 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 merger event just solved some unsolved problems in the swaying jet, and at the same time further affirmed the physical properties of the swaying jet. .
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 last piece of the puzzle in the theory of relativity broke too many theories that everyone insisted on. It rejected the theory of dark matter simulation, and at the same time restricted gravitational waves and The wave velocity difference of electromagnetic waves.
Any new alternative theory must assume that gravitational waves travel at the same speed as electromagnetic waves.
among them,
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.
