Chapter 155 Cone
It is now the 80th year of the Cataclysm Chronicle and the 17th year since Zhou Cheng was sent to Mercury.
When Project Mercury was proposed, these approximately 190 frozen embryos had just entered the thawing and cultivation stage. By the time Zhou Cheng left, they had already been born and become babies.
Now, they have become young teenagers.
Standing next to the railing on the second floor of the school, watching the children playing and fighting in the playground, Liu Yu couldn't help but smile.
She seemed to see herself and Zhou Cheng at this age.
We were like this back then, too. Sometimes we would be sad, sometimes we would be heartless, sometimes...
Smiling and shaking his head, Liu Yu walked towards his office.
Class is about to start, it's time to get ready.
When she passed by the mirror, she paused slightly and looked carefully at her appearance in the mirror.
In the mirror, there was a woman with fair and smooth skin, tall figure and slender body.
Thanks to good living habits, the passage of time did not seem to have left many traces on this body. But if you look closely, some details reveal them.
There are crow's feet at the corners of the eyes, the flesh on the neck is slightly loose, and there are a few gray hairs...
"Before I knew it, I was already 40 years old."
With a sigh, Liu Yu walked into the classroom.
When they saw Liu Yu come in, the children immediately stopped fighting and sat down in their seats properly.
"Today, we're going to talk about the introduction to gravitational waves. Everyone, please turn to page 66..."
In my old age, the children's curriculum was quite tight. At the age of 17, I had already learned university-level physics.
After teaching for a while, during a break, a fat boy raised his hand.
"Teacher Liu, are the gravitational waves you're talking about the same ones the World Government mentioned earlier? If we can just learn how to create them, can we save civilization and the world?"
A smile appeared on Liu Yu's lips: "Yes."
"good."
The fat boy nodded vigorously: "With so many of us, we can definitely all learn how to create gravitational waves!"
"Okay, you must do your best."
In this class, the students listened very attentively.
Time passes quietly.
After finishing the course and returning home, Liu Yu habitually turned on the computer and visited a web page.
The web page is filled with densely packed names.
This is an obituary website that specializes in counting the names of people who died the day before and then publishing them.
After taking a look at the statistics, Liu Yu discovered that the number of deaths on this day seemed to be higher than any previous day, reaching tens of thousands.
The names of some public figures are listed first.
After taking a look, Liu Yu was somewhat surprised to see the name of the first decision maker.
Suddenly, Liu Yu realized that he was now an old man in his eighties.
As I read further, I saw more familiar names.
Li Defu, Zhao Dafang, Mo Wenjing...
They are all scientific pioneers of the older generation.
But in Liu Yu's memory, their physical condition seemed to be fine. How could it suddenly...
Recalling the last time he saw them, Liu Yu sighed softly.
They work so hard.
As if they were afraid of not being able to contribute their knowledge and wisdom, they put in too much effort and energy into the "gravitational wave transmitter" project.
At such an old age, and still working so hard, it is normal for him to collapse at work.
Liu Yu also knew that many more people were busy at work day and night, overdrawing their already limited vitality.
In fact, this desperate state has been the norm in recent years.
Even myself, isn't it the same?
After all, this is the last charge of human civilization...
After taking a quick look at the recent progress, Liu Yu hurriedly washed up and lay down on the bed.
I still have two classes and three exchange meetings to attend tomorrow.
A tragic and heavy atmosphere enveloped the entire human world.
There were no passionate slogans, no enthusiastic mobilization. People just kept moving forward in silence.
Time passed quietly, more and more people fell down, and the young people grew up quickly and gradually joined the scientific research team.
The charge never stopped.
In this endless charge, in the 83rd year after the catastrophe, when the global population dropped below 100 million for the first time, the human world's research on "gravitational wave transmitters" finally made its first breakthrough.
A recent physics graduate published a paper describing a peculiar structure.
The cone made according to this structure will be able to convert about one hundred millionth of its energy into gravitational wave radiation when it rotates at a speed of 600,000 revolutions per minute.
This is an unprecedented breakthrough in the history of gravitational wave transmitter research.
For a moment, the entire human world was boiling.
While people were excited about this progress, they also realized another thing.
Although the extraordinary ability of this structure to convert energy has been proven through mathematics and theoretical calculations, it is almost impossible to apply it in reality.
To maintain its own structure while rotating at such a high speed requires extremely high material performance, which is impossible for people to manufacture.
At the same time, its rotation speed is too high. For a cone with a mass of 1 kg, the instantaneous energy is too huge, and people cannot manufacture a rotor that meets the requirements.
But regardless, this is still a huge breakthrough.
Based on this breakthrough, people began to try to use mechanical or engineering methods to achieve this requirement.
In the blink of an eye, another year passed and people's research made no progress.
There is no way. Even in its heyday, with all the power of civilization, it is unlikely that equipment that meets the requirements could be produced, let alone now.
But in this situation, the emergence of another paper once again shocked the entire human world.
After carefully reading the content of this paper, Liu Yu was also surprised by its wild imagination, and at the same time, shocked by the detailed calculation and reasoning process.
"If that's the case, maybe it really works..."
Liu Yu muttered to himself, holding the paper, and quickly rushed to the World Government Conference Room.
The person who proposed this paper is a girl with acne and a youthful look on her face.
Facing such a big scene for the first time, she seemed a little nervous and at a loss.
Looking at the girl, Liu Yu suddenly felt that she looked familiar.
At this time, the girl also saw Liu Yu and was instantly surprised: "Teacher Liu! You are here too? I am Sun Huiya, from Class 3 of High School, and I am your student!"
Liu Yu suddenly remembered and couldn't help but smile: "It's Huiya, it's okay, don't be nervous."
With Liu Yu's comfort and encouragement, Sun Huiya gradually calmed down.
Facing the room full of white hair, her clear voice rang out.
"My idea is this..."
