I really don't want to lie down and win

"truth..."

"More magical than the wildest fantasies!"

words fell,

A large blackboard appeared beside Xu Mang, filled with complex mathematical formulas.

"Some people think that there is only a theoretical possibility between laser interference and gravitational waves, and there is no real possibility." Xu Mang tapped the blackboard lightly, and said calmly, "This is the truth!"

Seeing this blackboard,

All netizens are confused...

What the hell!

Too fucking hardcore, right?

but...

There are even a very small number of people whose expressions became more solemn after seeing the mathematical formulas on the blackboard.

......

Chapter 392 The whole world has this idea (3/3, post it for teenagers and add more)

It wasn't just ordinary netizens who watched Xu Mang's live broadcast. Many scientific researchers were also among them. Many staff members of the Joint Laboratory for Gravitational Wave Detection were watching Xu Mang's live broadcast with their mobile phones.

Originally, these people came to see the jokes. After all, using laser interference to detect gravitational waves is a bit mysterious in itself, but... when I saw the mathematical formulas on the blackboard, I was surprised to find that there was something in it.

"I think..."

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

"Of course it was shown to us," said another researcher. "Even I couldn't understand it a little bit."

At this time,

Xu Mang started his explanation. First, he explained the working principle of laser interference. A beam of laser light travels in two mutually perpendicular directions after passing through a semi-mirror, and then reflects back through the mirror and converges again.

The converged laser light cancels each other out by interference. Once a gravitational wave passes through, the distance between the reflector and the half-mirror will be changed, and the interference phenomenon will be changed, thereby detecting the gravitational wave.

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

"understood!"

"I understand too!"

"Wait for me, I'll understand right away!"

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

first step,

Xu Mang explained the change of time and space, the principle of the constant speed of light, and re-deduced the process, and then proved the principle. Here Xu Mang explained the constant speed of light to the public by using the argument in the systematic analysis of stellar aberration.

"..."

"..."

"..."

What the hell!

it's over... it's over...

Can't understand from here on!

Most of the netizens who watched Xu Mang's live broadcast were completely dumbfounded at this time, especially the assumption made by Xu Mang, what are the two types of light from stars, the light speed is set to C and c, and C is less than c, the moment when c is emitted is zero, and the moment C emits is T...

After Xu Mang explained that the speed of light is constant, he brought up a very important concept. The laser is no longer a ruler to measure the change of the side length, but the change of the time when light passes through each side.

From distance to time, Xu Mang completed a qualitative leap, and it was almost the same with Xiaoman to complete the qualitative change.

Then he showed the public the specific results of using the 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 too many examples all over the world.

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

"Now!"

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

suddenly,

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

"Happy time is always so fast, I want to say goodbye to everyone." Xu Mang sat in front of the camera solemnly, and said to the camera: "This live broadcast is just to tell some people, don't question my thoughts, especially Those well-known big Vs who scolded me on the Internet."

"Questioning me...it's easy to make you shut yourself up." Xu Mang smiled and said, "Okay...the live broadcast is over here, if there is a chance, see you next time!"

words fell,

The screen goes black.

at the same time,

In the Joint Laboratory for the Detection of Gravitational Waves,

Being quiet is a bit scary, everyone is almost stunned, this... proves it?

"It's over...It's over!" A researcher said: "There has been a strong competitor since then, and I am also convinced...Is this all right?"

"How did Xu Mang discover this?"

"It's kind of weird," said another researcher.

Everyone panicked for a while, Xu Mang's appearance was like a time bomb, which would detonate the audience anytime, anywhere, but since the incident had already happened, he had no choice but to accept this situation. People have stabilized everyone's restless hearts.

"Don't panic for now." 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 more complicated than proving laser interference. leading position."

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

"Professor Luo..."

"The situation is a little... 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 lot from gravitational waves!"

"Ugh..."

"This is also something that cannot be reversed." The person in charge surnamed Luo sighed: "It is also my problem. I strongly opposed Fuda's joining at the beginning, thinking that Fuda lacked excellent astrophysics researchers. As a result... I never expected a monster like Xu Mang to appear."
