At this moment, Liu Jianguo's voice fell.
The little beauty called Liu Xinna also widened her eyes, her heart pounding.
Fermi's Parabola was a topic that only the top students of China's Aerospace University could study!
How could a high school student explain it clearly?
not to mention
This person actually wanted to reveal the real reason why humans were unable to discover extraterrestrial civilizations!
And this was simply impossible!
Even top physicists couldn't do it, alright?
Thus, while Liu Xinna was shocked, she quickly went to the app store and helped her grandfather download the Huyu platform app.
Although she said that she was watching the live broadcast with her grandfather, Liu Jianguo, to broaden her horizons.
but in fact
She was a little unconvinced and even wanted to expose He Xiao!
Why is it that you can broadcast Fermi's Parabola and talk about aliens while we are all high school students?!
What eighteen-year-old youth, well-read, number one in the world
Are you that amazing?
You must be bragging!
If there was something that Crane Sky could not explain clearly in the live broadcast room later.
Then, she would tell her grandfather about the flaws of the live broadcast without hesitation.
Because she wanted to strike a blow to this He Xiao's spirit!
However, at this moment.
The moment Liu Xinna and Liu Jianguo's granddaughter clicked into Crane Sky's live broadcast room.
"Boom!"
The moment he looked at Crane Sky!
The two of them were dumbfounded!
Liu Jianguo's murky eyes suddenly burst with a bright light, as if he had discovered a peerless jade!
Liu Xinna was stunned.
just because
She was completely shocked by the wealth of theoretical knowledge in front of her.
She was completely stunned by the scene in front of her!
He Xiao's blackboard was filled with all kinds of calculations.
He was using the Kardashev index to calculate the current status of Earth among the space civilizations!!!
"Ka, Kardasev index!"
"There's more! That's Fermi's paradox!"
"Oh my god, so he's really explaining the level of Earth's civilization!”
"But he's only an eighteen-year-old child. How could he know these things?!”
In the study room, Liu Jianguo put on his presbyopic glasses, his hands trembling with excitement.
Because he really didn't dare to imagine it.
An ordinary high school student actually knew about the Earth's development index!
And most importantly!
This person actually knew how to use an exponential formula to calculate Earth's current space civilization level!
And this was something that he could never have dreamed of!
On the other side.
Just as Liu Jianguo, Liu Xinna, and the grandfather and granddaughter entered the live broadcast room to watch.
He Xiao didn't notice it and continued to calculate crazily on his blackboard.""Students, we have just calculated the current power output per second of humans on Earth through the Kardashev index. It is about 2× 10^13 W per second.”
"Then, on the other hand, we can also calculate that our current civilization index should be around 0.73.”
"In other words, the current progress of humanity is far from reaching level 1 space civilization.”
"Because with our current technology and the use of Earth's resources, our Earth civilization is only equivalent to a level 0.73 space civilization!”
Boom!
What did you say?
0.73 A space civilization!
When Crane Sky's calculation results came out…
The live broadcast room was in an uproar.
The bullet screen exploded, and the netizens were all in shock.
"Oh my god, I didn't expect our current Earth civilization to be so powerful. It's only a level 0.73 space civilization!”
"Crane Sky is awesome! You can even calculate this. Speaking of which, these densely packed formulas are making my eyes dizzy!”
"Haha, who are you? Who was Teacher Crane Firmament? Can the two of you compare?"
"Hey, hey, everyone, have you noticed a problem so far?”
"You have to know that the numbers we calculated on the blackboard just now were all huge numbers that were raised to the power of a dozen or more, but, but Crane Sky seemed to have calculated them all by mouth.”
"It seems like he has never used a calculator before!”
"What the f * ck? What did you say? Impossible!"
"No, you haven't used a calculator before? Was this number a guess? Quick, then let's hurry up and see if the streamer's calculation is correct!”
As he spoke.
Many netizens in the live broadcast room had already turned on their phones or picked up the calculators on their desks to calculate.
Even Crane Sky's genius cousin and Liu Xinna who was far away in Jiangnan Province!
While the two girls were not convinced, they kept pressing the calculator to test if Crane Sky's numbers were accurate.
just
Boom!
Five minutes later, the two girls raised their heads at the same time.
Their eyes were filled with endless worship for He Xiao!!!
because
Both of them were blinded by the results of the calculations!
After all, who could believe it?
Five minutes!
Five whole minutes!
Even if they used their calculators, it would still take them five minutes to get the super complicated answer.
However, Crane Sky had just written the formula on the blackboard with chalk and calculated it in his mind in seconds!
The result was exactly the same, even more than a calculator!
What the f * ck!
What kind of terrifying human was this?
This was simply a god!
No!
Even a god probably couldn't do this!!
"Sigh, what a pity.”
"Liu Jianguo, are you old and muddle-headed?”
On the other side, when Liu Xinna put down the calculator in her hand and looked at Crane Sky, there was no longer any contempt in her eyes.
In the study room, Liu Jianguo was pounding his chest and stamping his feet. He looked up at the sky and sighed, full of regret.
Damn it!
Damn it!
He didn't expect that he had worked in the field of scientific research in China for so many years.
In the end, he even lost all his face in front of his own students!
After all, if it wasn't for his student, Little Wang, who had called him repeatedly to urge him to watch the live broadcast, he would have died.
Then, he would very likely become a major criminal in the history of science in China!
Because he had missed out on a top genius who could make China rise!!!
"Then, we have just calculated the current level of civilization on Earth. What should we do next?”
" Dear students, next, we will officially reveal why we humans have been unable to discover alien civilizations."
In the live broadcast room, the previous shock gradually subsided.
He Xiao wiped the blackboard and continued writing.
At the same time.
The bullet screen in the live broadcast room was filled with question marks on all the black people's faces!
What the f * ck?
Speaking of which, he had been talking for more than an hour?
Did he just get to the main topic?
"Oh my god, is this the official reveal? So we were just preparing for this lesson?”
"Haha, wonderful! It's too f * cking exciting!"
"My friends, so what if we're only starting now?”
"To be honest, the content just now was already shocking enough.”
" I'm sure the following content will shock our worldview and bring a new side to our life experience!”
"That's right, I like to hear it. Streamer, tell me about it quickly. I can't wait.”
“......”
At this moment, Liu Jianguo was also staring at his phone.
He looked at Jiang Chen's writing and explained,""Humph, these guys actually accused Crane Sky of explaining too slowly?”
"If it weren't for today, Crane Sky would have spent an hour explaining all the knowledge involved in this live broadcast before revealing the secret.”
"I think most of the people in the live broadcast room will be confused at this time. They won't know what answer He Xiao is talking about.”
Liu Jianguo had been teaching at Qingbei University for many years.
He knew very well that He Xiao was a super genius that he hadn't seen for thousands of years!
but
The other people watching the live broadcast were not geniuses.
They were just ordinary people!
If this live broadcast was really from He Xiao's perspective, he would quickly explain the incomparably profound knowledge of the universe to the netizens.
At that time, everyone would be dumbfounded!
Because they simply couldn't understand!
Only a step-by-step and step-by-step explanation could perfectly complete today's teaching and let everyone truly understand the answer to this live broadcast!
"No!"
However, just as Liu Jianguo was explaining for He Xiao with a smile.
He seemed to have thought of something and could not help but frown.
A trace of doubt appeared in his eyes.
Who was Liu Jianguo?
He was the dean of Qingbei University, who had been teaching for decades and more than half of his life!
It was also because of his rich teaching experience over the years.
Only then did he know how to teach so that the students could understand the knowledge more thoroughly.
How to answer questions and how to ask questions, only then could he grasp the rhythm of the class, only then could he make the class seem lifelike and dreamlike!
but
The Crane Sky in front of him today made him feel a little strange.
Because the latter was merely an eighteen-year-old youth!
However, Crane Sky was able to make a lesson that was originally extremely profound and boring so simple and clear, lively and exciting!
He was completely superior to the so-called great teachers in many universities!
It was even better than his own lecture!
Where did he get such rich teaching experience?
"Genius!"
"This is a genius!"
In the study, Liu Jianguo stared at the wonderful live broadcast on his phone and couldn't help but nod and praise,""Nana, you have to know that there are tens of millions of students in China, and there are too many outstanding people among them.”
"Normally, a student would only be able to solve this difficult problem by himself.”
"However, what if he not only knows how to solve this difficult problem, but can also explain it to others! Let the others hear it clearly and understand it.”
"That is the most powerful part!"
After that, Liu Jianguo smiled and stroked his beard while looking at his precious granddaughter, Liu Xinna.
He wanted to take this opportunity to teach his granddaughter a lesson and let her understand what a true study god was!
just
Just as he turned his head.
F * ck!
Liu Jianguo was dumbfounded!
Dumbfounded!
He had been talking here for a long time.
This precious granddaughter of his actually did not even look at him from the beginning to the end!
He was playing the lute to a cow!
In the study, Liu Xinna was not in the mood to listen to Liu Jianguo's story at all.
She rested her chin on her hands, her eyes shining as she stared straight at the screen.
It could be said that she was completely immersed in the ocean of knowledge.
She was completely immersed in Crane Sky's live broadcast!
At the same time, on the other side.
"Crane Sky, I beg you, hurry up and teach!”
"Yeah, why haven't we discovered aliens yet? Why don't you explain a few reasons?”
"Yes, yes, yes. I think once this reason is revealed!”
"Tonight, the host will definitely make it to the trending searches and become popular throughout the entire scientific community!”
"That's right, that's right! When that time came, all the experts and scholars would realize that their years of research were not as good as an eighteen-year-old streamer! Just thinking about it makes me laugh to death!"
“......”
At this moment, the bullet comments were overwhelming and flooding in like crazy.
When Crane Sky saw this, he pushed up his glasses and chuckled.
The answer.
He naturally had to announce it!
To be honest, the shock value in his system was about to reach 100,000.
How could he give up such a crucial opportunity so easily?
"Dong dong! Students, we have explained the total number of intelligent alien civilizations in the universe. There are as many as 100 trillion! He even calculated the amount of resources needed by civilizations of different levels.”
"Then…"
"Why haven't we found any traces of aliens yet?”
"Let's take a look at the most impartial views in the scientific community.”
In the bedroom, Crane Sky wrote down a few numbers on the blackboard as he spoke.
" The first common explanation."
"That is, extraterrestrials have indeed visited Earth.”
"However, at that time, we humans had yet to appear. Even if there was any contact before, it had nothing to do with us humans and could not be passed down!”
" As for the second common explanation.
"The Milky Way galaxy we are currently in has actually been completely colonized by a super alien civilization from another galaxy!”
"As for our Earth, it was neglected because it lived at the edge of the Milky Way.”
"This is like the European countries colonizing the American continent. However, the Inuit tribe at the northernmost edge of the American continent only knew about this after many years.”
"It's because…"
"They are too primitive and backward. They are not worthy of the European colonists 'attack!”
" Similarly, perhaps for a powerful alien civilization, our Earth's current level is too low and is of no value at all.”
" There is absolutely no need for the super civilizations to send a fleet to a remote corner and conquer us!”
On the other side, Crane Sky was telling the story vividly.
The voice fell.
In the live broadcast room, everyone fell into deep shock and thought.
Seeing this situation.
He Xiao struck the iron while it was hot, and wrote down the third explanation on the blackboard:
"Students, as for the third explanation…”
"That can be said to be the law of the Dark Forest that we are familiar with.”
Whoosh!
What was that?
Dark Forest Law?
This was a little familiar!
Hearing this term.
Many of the netizens in the live broadcast room revealed a look of realization.
However, there were still many netizens who couldn't help but post on the bullet screen: "Host, what is the Dark Forest Law?”
"Yeah, hurry up and tell me about it. It feels so awesome!”
"That's right! The name of the Dark Forest Law, could it be that the universe we are currently in is a vast forest?”
