Not only ordinary netizens were watching Xu Mang's live broadcast, but many scientific researchers were also among them. Many staff members of the Gravitational Wave Detection Joint Laboratory were holding their mobile phones to watch Xu Mang's live broadcast.

Originally, these people came to see a joke. After all, using laser interference to detect gravitational waves is a bit fantasy in itself. However, when they saw the mathematical formulas on the blackboard, they were surprised to find that there was some content.

"I think"

"This is not a live broadcast for ordinary netizens, this is a declaration of war against us!" said a researcher from the Gravitational Wave Detection Joint Laboratory: "I don't believe those netizens can understand such hard-core stuff."

“Of course it was shown to us,” said another researcher. “Even I couldn’t understand it at all.”

At this time,

Xu Mang started his explanation, first explaining the working principle of laser interference. After passing through a semi-lens, a laser beam moves in two mutually perpendicular directions, is reflected back by a mirror and re-converged.

The converged lasers cancel each other out due to interference. Once a gravitational wave passes through the middle, the distance between the reflector and the semi-transparent mirror will change, and the interference phenomenon will change, thus detecting the gravitational wave.

In order to better understand this concept, Xu Mang also made a model. He took out a laptop and displayed the model in front of the public.

"Got it!"

"I understand too!"

"Just wait for me, I'll understand soon!"

Under Xu Mang's model animation demonstration, most people basically understood the principle of how laser interference detects gravitational waves. However, this is not the final challenge, because very hard-core stuff is coming soon, and a lot of mathematical formulas are coming.

.

first step,

Xu Mang explained the changes in space and time and the principle of the constant speed of light, and re-deduce the process, and then proved the principle. Here Xu Mang used the argument in "Systematic Analysis of Stellar Optical Aberration" to explain to the public that the speed of light is constant.

""

Damn it!

It's over, it's over

I can’t understand it from here on!

Most of the netizens who watched Xu Mang's live broadcast were completely confused at this time, especially the hypothesis Xu Mang made, what are the two kinds of light from stars, and the speed of light is set to be c and light, c is less than, the time of emission is zero,

The time when c is emitted is t

After Xu Mang explained that the speed of light does not change, he brought up a very important concept. The laser is no longer a ruler to measure changes in side length, but the change in the length of time when light passes through each side.

From distance to time, Xu Mang completed a qualitative leap, which is almost the same as Xiaoman's qualitative change.

Then he showed the public the specific results of measuring using a laser as a ruler. This result was not experimental data, but was completed under a hypothetical condition. In fact, Xu Mang just took it from other people's calculations. After all, theoretical calculations,

There are so many examples around the world.

Finally, the highlight of this live broadcast is how to calculate the change in the duration of light passing through each side. After half an hour of hard-core explanation, Xu Mang finished explaining the mathematical formulas on two blackboards, almost going through the process from zero to one to infinity.

"Now!"

"We see that the numerical results on both sides are the same. It is basically certain that laser interference can also detect gravitational waves by measuring changes in the passage time of light, and this method is more scientific!" Xu Mang said with a smile.

Suddenly,

Netizens typed the words 666 one after another, along with the words Professor Xu is awesome.

"Happy times always come so quickly. I want to say goodbye to everyone." Xu Mang sat in front of the camera seriously and said to the camera: "This live broadcast just wants to tell some people, don't question my ideas, especially

Those public intellectuals who scolded me online."

"Doubting me will easily make you autistic." Xu Mang said with a smile: "Okay, the live broadcast is over. If there is a chance, we will see you next time!"

The words fell,

The screen goes black.

at the same time,

In the Joint Laboratory for Gravitational Wave Detection,

It was a bit scary to be quiet, and everyone was almost stunned. Does this prove it?

"It's over, it's over!" said a researcher: "Now that we have a strong competitor, is it okay for me to accept this?"

"How did Xu Mang discover this?"

"It's a little bit incredible," another researcher said.

People were panicked for a moment. Xu Mang's appearance was like a time bomb that would detonate the whole place anytime and anywhere. But now that it had happened, we could only accept this situation helplessly. Fortunately, at this time, the person in charge of the Gravitational Wave Detection Joint Laboratory

People stabilized everyone's uneasy hearts.

"Don't panic yet." The person in charge said: "We have more experience than Xu Mang. Even if he has the equipment to detect gravitational waves, the next work is much more complicated than proving laser interference. We still maintain

Leading position."

When the person in charge returned to his office, a middle-aged man soon found him.

"Professor Luo"

"The situation is a bit tricky!" The middle-aged man frowned and said seriously: "Xu Mang is an opponent that cannot be ignored. It is very likely that we will suffer a big loss from gravitational waves!"

"well"

"This is something that cannot be reversed." The person in charge surnamed Luo sighed: "It's also my problem. I was strongly opposed to Fuda joining in. I thought that Fuda lacked excellent astrophysics researchers, but I never expected that the result would come out.

A monster like Xu Mang."

at first,

There was indeed Fuda's name on the joint exploration list, but it was crossed out by this person named Luo. The reason was very simple. Fuda did not have relevant talents. At that time, Fuda did not have top astrophysics researchers in related fields.

.

However, Xu Mang's appearance completely changed this situation.

half a year,

From being unknown at that time to becoming an authority in this field now, this experience is almost the same as cheating.

"what to do?"

"Are you cooperating with Xu Mang?" the middle-aged man asked.

"It's hard!"

"I heard that Xu Mang has a very stubborn temper." Luo said, "The reason why he initiated the same project as ours was because he lost his temper when he heard that the joint project was not going to be expanded. He never thought that it would happen.

It’s stylish.”

The words fell,

Luo shook his head helplessly: "It was a mistake."

"Right!"

"Tell everyone not to have any dissatisfaction with Xu Mang, let alone use any means to make Xu Mang's scientific research career difficult." Luo said seriously: "We are engaged in scientific research, not conspirators.

, if anyone continues to talk nonsense online and provoke the other party, I will have no choice but to fire him."

"good!"

"I will send a notice immediately." The middle-aged man nodded and said cautiously: "What should I do about Professor Luo's previous situation?"

"The entire laboratory is notified of criticism!"

"Understood."

When the live broadcast ends,

All the big public intellectuals who had been crazily criticizing and insulting Xu Mang on Weibo were shut down. Faced with the condemnation from many netizens, almost all the big public intellectuals chose to remain silent and pretend to be dead. Some smart ones simply closed Weibo.

After the storm passed, Weibo was reopened and continued to lead the way. However, Xu Mang's reputation returned to its previous state, and was even more prosperous than before. Among his many titles, a brand new title was added.

Hardcore science popularizer

It's so hardcore that you can't even understand what's being said.

That night Xu Mang was invited to report by various media, and the live broadcast content was even made into video clips by others.

soon,

Xu Mang's live video was translated into English and began to spread across the ocean and Europe. Many scientific researchers watched the video and were surprised by Xu Mang's conclusion, but they quickly discovered a problem.

The video starts at 37 minutes and 30 seconds and ends at 38 minutes and 5 seconds. The two laser interference devices appearing in this picture are very familiar!

etc,

Isn’t this just MIT’s failed work?

mit,

Institute of Physics.

Professor Delwhit had just watched Xu Mang's video. At this time, he was so confused that he did not expect that the failed device he built would be resurrected under Xu Mang's theory and sold by himself for 10 million pounds.
