"If the mass of a star is less than the Chandrasekhar limit, it will eventually become a brown dwarf or a white dwarf. And if it exceeds this limit, the final gravitational collapse of the supergiant will produce a neutron star or a black hole."

This is what is written in black and white.

The teacher who taught the class had left long ago, and there was only one girl left in the classroom who was sleeping on the table in the last row.

Her notes are very detailed.

Careful identification is the birth of a star and its future.

"The primordial stellar cloud of dust and gas collapsed under the pull of gravity and formed a star.

The lowest mass stars (brown dwarfs) emerge and remain unchanged until they burn out.

Main sequence stars burn hydrogen in their cores. Distinguish between one solar mass, ten to thirty solar masses, and more than thirty solar masses.

When the hydrogen fuel is exhausted, ammonia nuclei form. An outer layer of gas begins to expand.

A red giant star of one solar mass has a carbon core surrounded by a hydrogen-burning shell and an outer layer of gas.

A supergiant. This is a massive star between ten and thirty solar masses.

A star with one solar mass collapses to form a white dwarf.

The gravitational collapse of a star with ten masses forms a neutron star.

The gravity of a star with thirty solar masses would eventually collapse into a black hole..."

The diary was beautifully written. But the girl fell asleep after writing this. She was still sleeping until the end of the class and all the students left.

At midnight, when the wind outside the window blew into the classroom, the girl finally woke up.

She raised her head and looked blankly at the empty classroom, raised her wrist, and the time projected by the holographic image showed that it was already 11 o'clock in the night.

"I'll go! How can I sleep so well?"

yes.

Sleeping from one o'clock in the afternoon to eleven o'clock in the evening really requires some real sleeping skills.

After hurriedly cleaning up, the girl hurriedly ran out of the classroom.

When she got outside, she discovered that this was not the school she was familiar with.

The sky glowed with a cool dark blue, and some white clouds as scattered as pages of a book hung diagonally in the sky as if they had been cut open with a knife. The water reached up to my ankles, and the wind felt cold on my body.

Only then did the girl really wake up.

She graduated a long time ago, thirty-nine years after graduation. For thirty-nine years, she has been studying stars, gravitational waves, black holes, and Dyson spheres.

This is the most cutting-edge and fashionable topic at the moment. As long as you have some achievements, you can apply for a large amount of special funds from the Supreme Academy of Sciences of the Yaxing Republic and set up a studio of your own. This girl is among them.

Outstanding...

When she graduated from college at the age of nineteen, she already had a master's degree in both astronomy and physics. A few years later, with her own efforts, she obtained enough funds for research and opening of research institutions.

But when she was twenty-seven, she was imprisoned for "violating relevant regulations and using stellar gravitational wave channel technology to send broadcasts to the Milky Way."

This is not an ordinary crime, and most people have probably never heard of it.

What is stellar gravitational wave channel technology?

Are there any dangers in broadcasting to the galaxy?

To put it simply, stellar gravitational wave channel technology is a very complex and cutting-edge technology that uses the energy of stars to amplify captured and edited gravitational waves, so that they can directionally transmit information to the entire galaxy.

In one book from a few centuries ago, this technology was described as "civilization's self-destruction."

Therefore, the Asian Republic, which had just reached the threshold of the second-level civilization, added this special crime to the latest amendment to the Supreme Act after the end of the Solar System 1 War.

"Ah...it turns out that I am a sinner now." The girl looked up at the sky and let out a slightly self-deprecating sigh.

What kind of mistake did she make to be locked up in this place and endure this endless torture?

Just because she had the audacity to send invitations to the entire galaxy?

How ridiculous.

Inferior, not worth mentioning.

She lay down, and the water behind her disappeared in an instant and turned into a big bed. To be honest, she no longer felt that she was being punished. In this cage built of pure consciousness, she was almost a god and a victim.

Beloved God.

Turning sideways, she saw another version of herself again.

There was no bed anywhere at this time, he was clearly still lying in the water, but the comfort had not disappeared.

The girl lying on her side gradually calmed down, and the water surface became as smooth as a mirror. She just looked at her other self.

But she didn't dare to touch her, or even try to greet her, because it was a very dangerous move. Contact with another self in a world made of pure consciousness could easily make herself confused. This is probably the only thing about this place.

The danger was there. They obviously didn't want to be executioners, because there was no specific law that could be pronounced in court saying that she should be sentenced to death, so they left her here to die.

Waiting to die?

"I won't wait to die." The girl regained her composure and changed from lying on her right side to lying flat on her back. At that moment, the gloomy sky became brighter. The breeze blew, and the water under her body turned into grassland. This was where she was born.

Place - Inner Mongolia prairie.

The earth is really a paradise-like place.

"Hey, it's very early today."

Strange sounds, strange people.

The girl stood up after hearing this, and the man had already walked less than five meters away from her.

He seems to be a good person, but she is not sure whether he is a human being... This is a necessary prerequisite, and it stands to reason that it should be determined before he is a good person.

"What's wrong? You look like you have a hard time today?" the man asked with a smile.

"Am I already crazy?" the girl asked.

"crazy?"

"Yes." The girl patted the non-existent dust on her butt and stood up and looked into the distance and said: "This is not the earth at all, is it? It is in a... uh... I can't tell exactly what it is, anyway.

Not on Earth."

"Well...then what do you think you saw?" The man asked a very philosophical question.

The girl didn't want to answer him because it didn't make sense at all.

She walked forward directly, ignoring the scornful gaze cast by the man. At the same time, she said as she walked: "Actually, I hate you, do you know?"

The man was a little surprised. He turned around and followed the girl and asked a little aggrievedly: "Why? What makes you hate me?"

The girl walked forward in the sea of ​​grass that was almost knee-high. She took very long steps and complained as she walked: "Thinking is a very interesting thing, isn't it? As long as you are willing to think, you can always create a lot of interesting things, but

As soon as you appeared, my head felt like it was locked. I couldn't think of anything. It felt like constipation. It's not that I didn't want to, but that I couldn't."

The man was amused by the girl's metaphors and directness. He knew what she was talking about.

That’s right too.

Before he appeared, the girl was the god of this world. Her consciousness could change the world at will, and the world was willing to favor her. But when she returned to this grassland unintentionally, her consciousness seemed to be locked.

, or... it's like a point that had no direction before accidentally encountered another point, so a line is determined and can no longer be arbitrarily created. This is not free, and it is really annoying.

"Well, I should say sorry, but I feel that this is not my problem, but yours. Why do you have to come back to the grassland? You obviously ran away from this place when you were seventeen years old.

And I vowed never to come back again." The man followed behind and said some shocking words.

The girl stopped, frowned and warned: "I'm warning you for the last time! Don't read my memory again!"

The man raised his hands, as if surrendering, and smiled honestly: "I will also explain for the last time, it is not that I am reading your memory, but that these are what you told me."

The girl was stunned when she heard this: "What? Me? Why should I tell you?"

The man thought for a while, scratched his face and said: "Maybe it's because of loneliness. As you said, you can't find anyone on earth who can understand you. You long for relief and freedom, and don't want to be trapped all your life.

In the resettlement area, you do not belong to the past of human history, you can embrace a booming human future, well... this sounds really! Very official! Haha!"

"Don't laugh!" The girl became a little angry, and she remembered everything.

It is true that it is not the man who can read her mind, but the fact that she tells the man what she is thinking. Logically speaking, it is always a happy thing for a girl to meet someone with whom she can chat in such a weird place.

.But as time passed and there was no further secret feelings, the girl felt that this man might also be a fake.

She has already gone crazy.

She knew that the Supreme Supervisory Committee was secretly conducting experiments with the Supreme Academy of Sciences on the pure consciousness space of the Hall of Thought a few years ago. Once such an experiment that violates moral ethics is formed, it will be like this. You can make a person's life disappear in the real universe.

, but it can make his soul eternally trapped in an eternal mental prison.

One second can also be divided into hundreds of years, thousands of years, tens of thousands of years or even hundreds of millions of years.

This sounds crazy.

Imagine that if this technology is not used to torture people, but to perfect the human upgrade plan, doesn't it mean that a monster with an ideology far beyond that of humans may be born?

What are they doing?

The man dared not laugh.
