The black tech madman who saves the world

Chapter 323 Earth Federation ([-])

"Proxima Centauri belongs to the category of red dwarfs in the classification of the sun. But if you want to understand red dwarfs, you have to start with the H-R diagram." Chen Mengchuan hugged his daughter with a smile.

The little girl's knowledge level is already at the level of hanging everything in the kindergarten, and she can speak well, and she spends most of the day playing with Ah Chen.

"Papa, what is a Heluotu? Is it a painting?" Chen Zhihui blinked her eyes with doubts.

"Haha, baby, the HR diagram is a scatter plot of the sun's absolute magnitude or luminosity versus spectral type, or effective temperature. If you want to put it simply, the HR diagram plots each sun on a On the chart, its temperature, color and luminosity can be measured, and it is not related to the position of each sun. The related color-magnitude chart plots the apparent magnitude and color of the star, these are usually for the sun They are drawn from star clusters at the same distance." Chen Mengchuan patiently said to his daughter.

The little girl obviously didn't have enough vocabulary to understand these words, she frowned and pouted.

"Haha, when you grow up, you will know. Baby." Chen Mengchuan picked her up.

"Papa, you should still say red dwarf, isn't it red?" the little girl asked again.

"Okay, then Dad will tell you. Red dwarfs, in fact, are often the planets we see at night, because they are too far away from us, and the sun is very close to us, so the red dwarfs look small, and the sun sees them." It looks big. The number of red dwarfs in the sun is relatively large, and the diameter, size and weight of most red dwarfs are less than one third of the sun. That is to say, most red dwarfs are smaller than the sun of."

"The surface temperature of these red dwarfs is also lower than that of our sun, and the light emitted is much weaker than that of the sun. Sometimes the brightness of many red dwarfs is only one ten-thousandth of the brightness of the sun. It looks like dimming Fireflies. Remember when I showed you the video of fireflies?"

"remember."

"Well, this is because the nuclear fusion of hydrogen elements inside these red dwarfs is slow. However, their slow nuclear fusion is also good, that is, their lifespan will be longer."

"Many red dwarfs with a mass less than 0.35 solar masses will have sufficient convection, and the helium element will be evenly distributed inside the star without accumulating in the core. In this case, the red dwarf will not expand into a red giant star, but Gradually shrink until the hydrogen is exhausted."

"Papa, how long will they glow?"

"Dad doesn't know how long it will shine, but according to scientific reasoning, they will maintain a stable luminosity and spectrum for hundreds of billions of years. However, due to the limited age of our current universe, no red dwarfs have yet developed to a later stage. So we have never observed the extinguishing of red dwarfs." Chen Mengchuan said with a smile.

He enjoyed the feeling of holding his daughter and telling her science stories.The little guy is very curious and interested in everything. I don’t know when he already knew a lot about astronomy. Most of them were told by A Chen, and sometimes Chen Mengchuan or Zhao Wanyu told her astronomy stories. .

"Brother Chuan, we're going there." Zhao Wanyu walked in with a smile.

"Mom!" Chen Zhihui struggled to jump down and rushed towards Zhao Wanyu.

Zhao Wanyu smiled and squatted down, holding her, and the mother and daughter kissed each other.

"Good boy, mom and dad are going to work, can you play with Ah Chen?" Zhao Wanyu asked with a smile.

"No. I want to play with my mother." The little girl was firm.

"Mom asked Chen to play cartoons for the baby, okay?"

"Okay! Long live mother, long live Ah Chen."

After a few minutes.

"Always show her cartoons, aren't you worried that she will be short-sighted in the future?" Chen Mengchuan complained.

"The intelligent soft light system of the graphene gravity screen can prevent myopia." Zhao Wanyu said with a smile.

Chen Mengchuan waved his hand helplessly. Zhao Wanyu is naturally more familiar with the various technological applications and technological products of Tianzhi Technology than herself, and she will not make jokes about her daughter. It should be true after all.

It’s true, people like me look at the screen every day, and the working hours are only a lot longer than they used to be on Earth, but it seems that eye drops are not used much anymore. When I was on Earth, I could drip a bottle of eye drops a week .

"Have you made an appointment?" Chen Mengchuan asked her.

Zhao Wanyu's smile subsided, and she nodded calmly, with a lot of determination in her eyes.

"Then let's go." Chen Mengchuan didn't say anything more.

The two boarded the gravitational ball together, and soon flew to the gate of another dimension.

Today is a big day for Chen Mengchuan and others.

After a period of secret promotion, the entire United Nations finally understood what Tianzhi Technology wanted to do.

Promote the Earth Federation!

The nations of the earth unite!
This time, Tianzhi Technology will take the stage!

Because Tianzhi Technology already has enough power and enough popular support.

What Tianzhi Technology needs to do now is to gather all the resources of the entire earth and make a unified plan.

Further liberate more human populations, release more educational power, and concentrate the power of the entire human race to face the future.

For Chen Mengchuan, this is the most important thing during this period of time, and it is also an urgent thing.

After this time, Tianzhi Technology will strive for the greatest authority to coordinate the earth. No one, any country, or any force can, and will not be able to stop Tianzhi Technology's overall planning this time.

The gravitational ball slowly landed on the square of the gate system of the different dimension.

Zhao Wanyu took Chen Mengchuan's hand and walked out of the gravitational ball.

In the entire square, there are already many people walking and guarding.This is a world class party.Countless political representatives from the top of the world gather in the city of Mars—Qiming City. Everyone will really understand Tianzhi Technology today, understand the culture of Tianzhi Technology, and understand the ultimate ambition of Tianzhi Technology, which is the level of the entire human civilization. Yes, an integration of endless racial hatred, endless national hatred, and endless national hatred.

All countries on the entire earth will be integrated today, will enter a brand new human era today, and will realize the highest social form that all countries will pursue today.

Tianzhi Technology now has the right to speak, and Chen Mengchuan does not intend to continue to remain silent.

In the not-too-distant future, among the interstellar civilizations that are about to be realized, the earth must be monolithic!
