Half-immortal civilization

The light of the brilliant Orion Nebula in the distance, spanning four light-years, can illuminate the back of the spacecraft porthole as bright as day.

"Old people" such as Zhang Jingyuan sit at the back of the hall and usually don't speak; some young people in front are very active.A huge, 20-meter-square projection of the starry sky now shows the eight main bright "stars" of the entire constellation of Orion.Seven of them are particularly bright, but the top one is somewhat dim.

A middle-aged man is preparing to explain.Of course, in today's Huaxia, you can't judge people by their appearance. Maybe they look like young people, but they are actually old monsters—the typical representative is the big boss.

Obviously, such a situation annoyed the comrades in the civil affairs department and the public security department, and this annoyance has not ended until now. Looking at the five or six hundred-year-old monsters on the record, I can only say, so powerless!

far away...

"Hi everyone, my name is Zhong Xinghui. Like my surname, I am from the Zhong family. Today, I will explain to you the situation of the Orion Nebula we detected; facing this strange interstellar environment, you must be prepared."

When Zhong Xinghui introduced himself, he was very proud!Also, as one of the most powerful families in the Chinese Empire today, they have the merits of being a dragon.From the construction of the Space Mirror back then, to hosting the Space Environment Science and Technology Research Department to promote the development of the empire, to the future exploration of the starry sky, the Zhong family is indispensable.Today, the elites of this family are indispensable to explore new and unfamiliar star fields.

Also, by virtue of merit and dedication.This family has been able to retain its title of marquis to this day!You know, the Huaxia Empire adopted a reduced hereditary system, so one can imagine how strong this family is.Even around the solar system, they even have their own galaxy and their own country!
For the national structure of the Huaxia Empire, the Pearl Starfield has also explored, but they can't learn it!In the rear of China's ancestral land, every galaxy is a country; but in the front, they are combined to form a huge empire, working together!This is a social structure well adapted to the survival of the universe.Everyone has their own interests, and they can also keep their own interests; and at the same time.The entire race has its own goals to pursue!

at the moment.This family, which has always taken the exploration of the starry sky as its mission, has allowed the most elite generation of the family to come to assist in the development and development of the empire.

Everyone sat upright, Zhong Xinghui explained.Contains all the efforts and achievements of this family.Of course, it will also become the key and guidance for China to explore the Orion Nebula.

See everyone is ready.Zhong Xinghui turned his head and began to explain.

"In ancient China, the constellation of Orion was called Sansuke. When pronounced shen and xiu, Shen is actually three, capitalized three. The reason is very simple. Just look at the three stars on Orion's belt.

According to the naming of our ancient culture, viewed from top to bottom, firstly there are two relatively wide positions, and there is a not-so-bright star in the upper middle. position, just above the mouth.

The next red one, located on the right shoulder of Orion, is a red giant star with a diameter of about 16 billion kilometers, which is almost equivalent to the orbital diameter of Jupiter and a little more.Red giant, this is the later stage of the star, which may evolve into the next nebula.

The red giant star was named Betelgeuse in ancient China.

Next on the left shoulder is Betelgeuse.

And there are three juxtaposed on the belt, which are Betelgeuse [-], [-], and [-].

The lower ones on the knees of the hunter pattern are Rigel on the right knee and Rigel on the left knee.

First of all, I want to popularize a little astronomy knowledge to everyone.Many people only know that there is Orion in space, but few people pay attention to it. From our perspective, the positions of many stars are actually biased.

For example, the red giant Betelgeuse does not belong around the Orion Nebula at all.Orion is about 1500 light-years away from the solar system, but this red giant is only 430 light-years away from the solar system.

Then there's Rigel, about 770 light-years away from our solar system.

After talking about these two examples, let’s talk about Betelgeuse. This star is actually a group of stars, and it was discovered only recently. The distance of light years (no specific information was found).Betelgeuse is also about 80 light-years away from the nebula. This is a super blue giant star.

Having said all that, I would like to say that the Orion Nebula, which we are targeting, is actually Betelgeuse.The star we see in the solar system is actually a nebula 16 light-years in diameter!
But what we need to pay attention to is that the Orion Nebula is not one. The entire star field, within a radius of [-] light years, is all nebula groups!Just like the white clouds in the sky, although each of them looks isolated, they are actually inextricably linked, like ribbons.

According to what we have observed so far, what we have been observing for a long time is this nebula with a diameter of 16 light years, which is also the closest to us, and it is also a relatively small one in this nebula group.

In the background, there is another large nebula covering a distance of up to 50 light-years.

So far, we've detected several danger zones in the nebula, places that appear to be particularly bright. "

"Is it a star that just exploded?" A worried officer suddenly asked.

"No, on the contrary, they died at least 300 million years ago!" Zhong Xinghui had a rare sense of humor!
"In 300 million years, the temperature should have dropped!?" The officer was puzzled.

"Because they are now in the resurrection stage!"

"?" The star died, but can it be revived in place?Many people looked at Zhong Xinghui, waiting for the other party's explanation.

"Yes, you heard it right, they are indeed in the resurrection stage. But after the resurrection, they are not stars.

As we all know, in ghost stories, the resurrected zombies are not human beings.Similarly, the revived star is no longer a star, but the product of the death of the star, a black hole!
Black holes, in everyone's understanding, must be the kind of existence that has no light and cannot be detected.For example, the black hole in the Pearl Star Field.But everyone is wrong, black holes also have several stages.

The black hole in the Pearl Star Field is in a stable period, and there is no matter around it that can be devoured.But the black hole here is in the growth stage.They wantonly devour the surrounding matter.

In the process of black hole engulfment, it will lead to the compression of energy, light, and some hydrogen, helium, and even lithium, etc., will be compressed.When these elements are compressed to the limit, a nuclear fusion reaction will erupt, releasing high temperature and radiation.

So those bright regions that we see now, are actually black holes, and feeding black holes at that!Its range of influence is about one light-year to one-and-a-half light-years.For the sake of safety, it is recommended not to enter at a position 2 light-years away from the luminous circle.According to theoretical calculations, the luminous circle is the extremely compressed nuclear fusion reaction area, and the distance from the black hole here will not exceed 5 million kilometers.

In addition, we should also pay attention to the fact that the nebula has another characteristic, that is radiation!Its radiation is completely different from that of stars.We know that the radiation of stars is directed.But the nebula is not, but from all directions!Maybe the fist-sized wreckage you see has a lethal dose of radiation.

To be precise, the nebula is also a kind of celestial body, and if we want to enter the interior of this celestial body, we will of course be attacked from all directions, that is, radiation.Just like our immune system.

And around those black holes, the radiation is even more intense.

The radiation components here are very complex, including general ray radiation, strong electromagnetic wave radiation, and even particle stream radiation!There are many neutron rays, gamma rays, beta rays, alpha rays, x-rays, etc.!
People say that roses are beautiful but thorny; and the nebula right now is the rose in the universe!

Well, my speech is over, do you have any questions? "

"Hello, Professor Zhong, I would like to ask, what is the explanation for the strange life we ​​have detected in the nebula at present? You know, our existing scientific theories cannot explain this phenomenon!"

"Not bad, lad. Unfortunately, I'm an astronomer, not a biologist. Well, I think you're off the mark!"

In my opinion, it should not be said that our current theory cannot explain this phenomenon; rather, it should be said that our theory will have a great development!This shows that carbohydrates, or silicon bases, etc., are not necessarily necessary for the development and evolution of life.

You see, in this universe, there are such beings who use nebula as their body, planets as their brains, and electromagnetic radiation as their nerves.Wow, what a treasure trove!
How lucky we humans are to encounter such a miracle when our development has slowed down a bit!

It's a miracle!Yeah?Boy, it's a miracle!We are lucky! "

Finally, Zhong Xinghui emphasized that this is a miracle.

"Yes, Professor Zhong, you are right, this is our nebula, a miracle, a miracle facing us!"

"Okay, what's the boy's name? Are you interested in being a researcher under me?"

"I'm willing to teach. My name is Xiaohao! The size is small." The young man said fiercely.

"Small? Oh, this is really a rare surname. I'll give you a month to pack it up, and then report to Nebula 7 spacecraft. You can find me then."

"Thank you, Professor!" Xiaohao rolled out of the meeting hall happily.

"Hello, Professor Zhong!" A middle-aged officer stood up, "I want to ask, will the intense radiation from the Orion Nebula affect our exploration and our safety?"

"Temporarily, we have discovered that virtual physics technology and energy protection layer technology can be used in combination to isolate all damage. But it is limited to the current exploration."

"Thank you!" (To be continued...)
ps: Extra episode: Professor Zhong Xinghui quietly asked Xiaohao: Young man, can you warm the bed?
Xiaohao smiled shyly: I made a good friend, he has been letting me learn to sleep on the floor.
