"Alright, my report is done."

Ding Yi bowed politely to everyone and prepared to step down from the podium.

Putting aside the time everyone was frozen, the scientists here were all older and more senior than him, and he had to show the humility of a junior.

"Wait a minute!" Christina stopped, "Why is it over?" Isn't the story just beginning? ”

"That's the story." Ding Yi said, "'Ziwei' is just below the exit of the Bilong Pond of the exploration base, now as long as Ms. Lin Xuexi orders, it can immediately rise to the ground and start, but don't start it while the collider is running, the radiation will interfere with it, and in order to prevent it from being discovered by Achilles and destroyed, I recommend that most of the time, try to keep it underground." ”

"You know that's not what she meant." An elderly scientist said, "We are all curious, what did you Chinese astronomers find behind that nebula after the 'Ziwei' was built?" ”

There is no doubt that the most curious people in the world should be scientists, otherwise, they would not be scientists.

In this distant story told by Ding Yi, whether he was intentional or unintentional, it did leave a suspense and mystery full of weight, and in the face of the truth that is close at hand and at your fingertips, how can these outstanding scientists from all eras give up?

"Don't you just need an antenna? I've now provided you with a world-class communications base, aren't you satisfied? ”

Ding Yi said a little angrily that he didn't plan to continue the story at all, because the back of the story is the real top secret.

"You're so stupid! Did it come from a feudal society? The welder said, he didn't expect these scientists who usually find unattainable to be so uncivilized, "Don't you understand? All the nations are gone, and even if we rebuild them, it will be a whole new one, and of course, all if we can defeat the Intelligence. ”

He was already fascinated by the story, and although he didn't understand some of the theories and jargon in the story, who couldn't be fascinated by the human exploration of the universe and space?

Ding Yi didn't expect that he was actually reprimanded by a humble welder, and was about to refute a few words, but Lin Xuexi couldn't help but laugh when he heard Lin Xuexi over there: "Okay! Don't sell it! ”

"You're not going to bother me with authorization again, are you?" Then she made a helpless expression, "Then I authorize you now, finish this story, no omission, no pause!" ”

Looking at this cute girl, Ding Yi's anger disappeared all at once, and his face turned red again.

"Okay." He picked up the stylus again and walked back to the screen.

"Actually, I was an intern of the Ziwei project back then, and I was 20 years old when the 'Ziwei' was completed." Speaking of this, Ding Yi subconsciously glanced at Lin Xuexi.

was able to be selected as an intern of Ziwei Engineering at the age of 20, presumably he was also very good back then.

But what he thought to himself at this time was: "If I didn't participate in the Ziwei project back then, but fell asleep directly after four years like her, I would still be only two years older than her now, and if I slept two years earlier than her, we would be the same age, alas!" Creation makes people! ”

He felt a little bitter in his heart, but he was also a little lucky, and even a little grateful for the accident caused by this earthquake, if it weren't for this accident, he and Lin Xuexi's long life trajectory that was far beyond ordinary people might never overlap, and it would be impossible to stand here and look at her flower-like smile.

"Through 'Ziwei' we found that behind the Iris Nebula is an Sb-type vortex galaxy, which is larger and older than the Milky Way."

"The Earth is about 60 million light-years away, and its diameter is at least 280,000 light-years, which is three times the size of the Milky Way galaxy in which we live."

"From the perspective of the earth, this galaxy belongs to the same Ziwei Yuan as the Ziwei Emperor Star, and we discovered it using a telescope called 'Ziwei', so it was finally named 'Xuanyuan', which is the name of the first emperor in the true sense of Chinese history."

"The star density of the Xuanyuan galaxy is much higher than we think. At that time, through the observation of 'Ziwei', the number of stars in the Milky Way was roughly estimated to be about 230 billion, and the Xuanyuan Galaxy, conservatively estimated that the number of stars would reach 70 trillion. ”

"And most importantly, most of the stars that can be observed in the Xuanyuan galaxy are main-sequence stars, and basically more than 90% of them are in the lower right position of the Hérault diagram, that is, they are yellow dwarfs like our sun, or orange dwarfs with a greater probability of habitable planets, and about 6% of red dwarfs, with only a few supergiants, blue dwarfs and white dwarfs."

"Most of these yellow and orange dwarfs have the same mass as the sun, or even smaller, and have a longer lifespan, so the probability of giving birth to higher life in this galaxy is quite large!"

"If we can't survive in the Milky Way one day, it would be a good idea to move to the Regulus Galaxy."

"And, we may have spotted a black dwarf!"

"Impossible!" The representative of France stood up and loudly retorted.

He is a university professor, and he still knows some basic astronomical knowledge: "The formation of black dwarfs takes tens of billions or even hundreds of billions of years, and the development of the universe is only 13.8 billion years old, and it is absolutely impossible for black dwarfs to exist!" ”

The other scientists also nodded, believing that the representative of France was right.

"My mentor had a mantra where he said: as a scientist, never use the word absolute, especially astronomers."

"I don't know if this sentence later became a famous saying, but the words of the ancients should have some truth."

After the story was told, Ding Yi seemed to be a lot more relaxed, and even made jokes.

"We observed a wandering red dwarf star, and when it passed through a void space, the phenomenon of Loch lobe overflow occurred."

"At first we thought it was a pulsar, but it didn't radiate at all, it couldn't be a black hole, the red dwarf wasn't swallowed, it lost some matter and continued to wander forward."

"From this we guess that the hidden star is a black dwarf, which does not burn and does not radiate, and is a cold, lonely death star."

"We have made many hypotheses about its formation, but one of the most convincing is that a binary system of two massive white dwarfs, each with each other's Lochlobes, transmits material from the Lagrange point to the companion star, causing the companion star to explode beyond 1.44 times the mass of the Sun, the Chandrasekhar limit."

"The mass of the host star is greater than 3.2 solar masses, which is the Oppenheimer limit, and it collapses into a solitary star."

"This solitary star began its wanderings in the universe as the explosion of the companion star pushed him into the distance."

"Then it encountered a white dwarf in the midst of a transition, which looted the burning hydrogen and helium from the planet's outer periphery, leaving behind a carbon core."

"White dwarfs continue to burn for tens of billions of years and then cool for tens of billions of years, and the fusion energy is sucked away, allowing it to skip the process."

"Most stars spend their old age peacefully, but it was killed suddenly."

"The carbon core, which had lost its external energy, continued to collapse and eventually became a hard, icy black dwarf."

"And this solitary star continues to wander, becoming a ruthless killer in the vast universe."

"It is extremely dense, second only to black holes, reaching 100 billion tons per cubic centimeter, and its ultra-high density makes its gravity, Loch limit, Hill sphere, and Loch lobe far greater than that of a star of the same size."

"The stars it encounters in its path will be plundered or swallowed, and its volume and mass will become larger and larger."

"But devouring matter creates high temperatures, right? Even if it's devouring planets at the edge of the universe. "Zou Dufeng questioned it, he is an authority on high-energy physics, and he can find the loophole in this hypothesis by listening to it." I have some understanding of Tsung-Dao Lee's 'non-topological soliton bag model', in the state of high temperature, the soliton solution disappears, the bag constant returns to zero, the phase transition of deconfinement occurs, the strong force of space disappears, and the whole planet will collapse and disintegrate, right? ”

Hearing the question, Ding Yi was so frightened that he hurriedly saluted, he didn't dare to be presumptuous in front of Zou Dufeng, "Zou Lao, we later did a lot of verification and analysis, when the temperature rises to a critical value, the non-topological solitons will indeed undergo a phase transition of deconfinement, the soliton bag will disappear, and the strong force will disappear, but the solitons will enter a strong coupling state similar to plasma, the temperature will continue to rise, the non-topological solitons will disappear, and the topological solitons and anti-topological solitons in the bound state will be produced, when the temperature reaches another critical point, A symmetrical recovery phase transition occurs, topological and anti-topological solitons disappear, and soliton pockets recover. ”

"So the high temperature will not destroy the soliton star, but will give it energy, making it easier for it to compress the newly plundered matter into solitons and become part of the soliton star."

"Suffice it to say that, apart from black holes, soliton stars are invincible in the universe, they can devour infinitely and expand infinitely."

"In the end, following the trajectory of massive celestial life, it is not difficult to calculate its outcome: it will collapse into a smaller base unit and a denser object."

"A sparse red giant will collapse into a white dwarf made of dense atoms, a white dwarf made of atoms will collapse into a neutron star, and a white dwarf with a larger mass will collapse into a quark star, a soliton star, a boson star, so what are the particles smaller than quarks, solitons, and bosons, I don't think I need to talk about them, right?"

"Yuan Qi particles!" Lin Xuexi hurriedly said, she didn't understand the conversation between Ding Yi and Zou Dufeng at all, but about Yuanqi particles, except for Zou Dufeng, she was the one who had the most right to speak. "Isn't that Yuan Qixing? And what about Yuan Qixing in the end? Will it collapse into a black hole? ”

"No, it won't." Ding Yi replied, "Black holes are another branch, and they are all close relatives based on white dwarfs. ”

"Imagine that the mass and density of this Yuanqi star are getting bigger and bigger, and the range of its gravitational influence is getting farther and farther, boundless, endless, and the distance within a radius of tens or even hundreds of light years is within its enveloping range, and its speed is getting slower and slower, until it stops near the last engulfed celestial body, and the surrounding celestial bodies are sucked by it, and countless dust and nebulae gather next to it, and as time goes by, new stars will be born inside, and this Yuanqi planet, which has finally settled down, is wrapped by countless celestial bodies, creating a galaxy. ”

"Therefore, the final conclusion of this hypothesis is that the star nuclei of all galaxies, including the silver nucleus of the Milky Way, may not be a black hole as the astronomical community generally believes, but a huge Yuanqi planet."

"And it's going to continue to devour, and it's going to swell."

"It never ends."
