Not only ordinary netizens watched Xu Mang's live broadcast, but many of them were also scientific researchers, and many staff members of the Joint Laboratory for Gravitational Wave Detection were holding their mobile phones at this time, watching Xu Mang's live broadcast.

Originally, these people came to see the joke, after all, using laser interference to detect gravitational waves is a bit fantasy in itself, but... When I saw the math formula on the blackboard, I was surprised to find some content.

"I think..."

"This is not a live broadcast to ordinary netizens, this is a declaration of war against us!" said a researcher at the Joint Laboratory for Gravitational Wave Detection: "I don't believe those netizens can understand such a hardcore thing." ”

"Of course, it was broadcast to us. Another researcher said, "Even I don't understand it a little." ”

Then

Xu Mang began his explanation, first explaining how laser interference works, a beam of laser light passes through a half-lens and heads in two mutually perpendicular directions, reflects back through the mirror and reconverges.

The converging laser light cancels each other out by interference, and once a gravitational wave passes through the middle, the distance between the mirror and the half-lens will be changed, and the interference phenomenon will change, so that the gravitational wave will be detected.

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

"Got it!"

"I get it, too!"

"Wait a minute, I'll understand in a moment!"

Under Xu Mang's model animation, most people basically understand the principle of how laser interferometry detects gravitational waves, but... It's not the ultimate challenge, because there's going to be a lot of very hardcore stuff coming right now, and a whole bunch of math formulas coming at you.

Step 1,

Xu Mang explained the principle of space-time change, the invariance of the speed of light, and re-deduced the process, and then proved its principle, here Xu Mang used the argument in "Systematic Analysis of Stellar Light Travel" to explain to the public that the speed of light does not change.

“...”

“...”

“...”

it!

It's over, it's over...

I don't understand it from here!

Most of the netizens who watched Xu Mang's live broadcast were completely confused at this time, especially the assumption made by Xu Mang, what star has two kinds of light, set the speed of light to C and c, C is less than c, the moment c emits is zero, and the moment C emits is T...

After Xu Mang explained that the speed of light does not change, he threw out a very important concept, the laser is no longer a ruler to measure the change in the length of the edge, but to measure the change in the time of light passing through each side.

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

Immediately after that, the specific results of using the laser as a ruler were shown to the public, and 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, there are too many examples of theoretical calculations in the world.

Finally, the highlight of this live broadcast, how to calculate the change in the duration of light passing through each side, under the hardcore explanation of half an hour, Xu Mang finished the mathematical formula of the entire two blackboards, and almost experienced the process of zero to one to infinity.

"Now!"

"We see the same results from the numbers on both sides, and it is almost certain that laser interferometry can also detect gravitational waves by measuring the change in the passage time of light, and this method is more scientific!" Xu said with a smile.

Suddenly,

Netizens typed the word 666 one after another, and it was accompanied by Professor Xu.

"Happy times are always so fast, 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 well-known big Vs who scolded me on the Internet." ”

"Question me... It's easy for you to be autistic. Xu Mang smiled: "Okay... That's the end of the live broadcast, and we'll see you next time if we have the chance!"

Words fall,

The screen goes black.

meanwhile

In the Joint Laboratory for Gravitational Wave Detection,

There was something terrible about the quiet, and everyone was almost confused, this... Does this prove?

"It's over... It's all over!" said one of the researchers, "Since then, there has been one more formidable competitor, and I'm also convinced... Is this all right?"

"How was this discovered by Xu Mang?"

"It's a little bit incredible. Another researcher said.

For a while, people were panicked, and Xu Mang's appearance was like a time bomb, which would detonate the audience anytime and anywhere, but since the incident had happened, he could only reluctantly accept such a situation, fortunately, at this time, the person in charge of the Gravitational Wave Detection Joint Laboratory stabilized everyone's uneasy heart.

"Don't panic just yet. "We have more experience than Xu Mang, and even if he has the equipment to detect gravitational waves, the next work is much more complicated than proving laser interference, and we still maintain a leading position," the person in charge said. ”

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

"Professor Luo..."

"There are some... It's tricky!" The middle-aged man frowned and said solemnly: "Xu Mang is an opponent that cannot be ignored, and it is very likely that we will suffer a big loss in gravitational waves!"

"Ugh..."

"It's something that can't be reversed. The person in charge surnamed Luo sighed: "It's also my problem, it's because I strongly opposed the joining of Fuda at the beginning, thinking that Fuda lacks excellent astrophysics researchers, and as a result... I never expected a monster like Xu Mang to come out. ”

Initially

On the list of joint exploration, there is indeed the name of Fuda, but it was crossed out by the surname Luo, the reason is very simple, Fuda did not have relevant talents, and at that time, Fuda did not have top astrophysics researchers in related fields.

But... The emergence of Xu Mang completely changed this situation.

Half a year's time,

From obscurity at the time to the current authority in this field, the experience is almost the same as hanging.

"What should I do?"

"Isn't it... Cooperate with Xu Mang?" the middle-aged man asked.

"It's hard!"

"I heard that Xu Mang has a very stubborn temper. The surnamed Luo said: "The reason why he initiated the same project as ours was because he heard that the joint project was not restored, so he lost his temper, but he never thought of it... It's done in a good way. ”

Words fall,

The surname Luo shook his head helplessly: "I made a mistake..."

"That's right!"

"Tell everyone, don't have any dissatisfaction with Xu Mang, and don't use any means to make Xu Mang's path to scientific research difficult. The surnamed Luo said solemnly: "We are engaged in scientific research, not conspirators, if anyone talks nonsense on the Internet and provokes the other party, I can only fire him." ”

"Good!"

"I'll give you a notice right away. The middle-aged man nodded and said cautiously, "Professor Luo... What about the previous one?"

"The whole laboratory circulates criticism!"

"Understood. ”

...

When the live stream ends,

In the face of the condemnation of many netizens, almost all the public Vs chose to remain silent and play dead, and some smart ones simply closed Weibo.

Wait until this turmoil has passed, reopen Weibo to continue to lead the rhythm, but Xu Mang's reputation has returned to before, even more vigorous than before, and among his many titles, there is a new title.

Hardcore science popularizers...

It's so hardcore, so hardcore that you can't understand what you're saying.

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

soon

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

Starting at the 37th minute and 30 seconds of the video and ending at 38 minutes and 5 seconds, the two laser interference devices that appear in this video are very familiar!

Wait a minute

Isn't this a failed work for MIT?

MIT，

Institute of Physics.

Professor Del Whitt had just finished watching Xu Mang's video, and he was in a state of confusion at this time... Unexpectedly, the failed equipment built by himself was resurrected under Xu Mang's theory, and was sold by himself for 10 million pounds.

Of course

That's not the problem, the important thing is that the laser interferometer is gone!

That's all there are for these two!

Thinking of this... Professor Delwhitt couldn't help but have a painful look on his face, and at this moment he felt that there was darkness in front of him, and he felt a sense of suffocation.

"Professor Delwhitt!"

"Professor Delwhitt!"

Then

A professor as old as Professor Del Whitt came to his office and said to Professor Del Whitt: "Have you watched a video on the Internet? Your laser interferometry equipment has been verified, and Professor Xu Mang from Huaguo has proved that laser interferometry can detect gravitational waves by calculating time. ”

Professor Delwhitt opened his mouth for a long time before he spoke, "I know... Professor Motz, I just watched this video. ”

"Oh?"

"Then can you build two more?" Professor Motz said with a smile, "I also need two such devices, if gravitational waves are detected, it will be a Nobel Prize-level discovery!"

“...”

"There are no drawings anymore. Professor Delwhitt said bitterly, "There are only two in the world... At that time, the whole public opinion said that it was impossible for laser interference to detect gravitational waves, and then I threw all the design papers into the fire in a fit of rage, unless I designed it all over again... However, it will take at least two years from design to completion. ”

Hearing Professor Del Whitt's words, Professor Motz was dumbfounded... His mouth opened slightly, but he didn't say it.

"Did you sell it for ten million pounds?" asked Professor Motz.

"Yes!"

"Of that, £1 million was left behind for my project as research funding, and the remaining £9 million was taken by the university for other purposes. Professor Delwhitt said helplessly: "Don't blame me, I wouldn't have been able to sell it without the school's consent, and we both thought it was a big profit at the time!"

Big money?

Yeah... It was a big profit at the time!

Almost cheated others more than eight million pounds, however... What now?

Do you still earn money?

For 10 million pounds, he took the world's only two laser interferometer devices, which were also used to detect gravitational waves, and once the results were achieved, he was sure to win the Nobel Prize in physics.

"Can you contact Professor Xu Mang?" Professor Motz said seriously, "We can provide funding to participate in his project!"

“...”

"Professor Motz believes in me... The whole world has this idea!"

meanwhile

Yang Jian received a phone call, which was an international call.

"Yang!"

"What is the relationship between Professor Xu Mang and you?!"

......
