233: Chapter 233: At least one super-civilization once existed within the solar system!

After saying this, he looked at the expression on Xiaoyu's face and couldn't help but want to laugh.

In this world, this hypothesis does not exist; in fact, it is a concept currently in his mind.

Speaking of this, he couldn't help but think of his past life, the first time he brought up this concept to several top astronomers in his think tank.

Those refined scholars' initial reactions were ten times more exaggerated than Xiaoyu's current one; they directly slammed the table and called it nonsense, science fiction.

The serious meeting room almost turned into a rare scene of physical altercations.

Fortunately, by relying on his superb physical contact techniques—for example, force—he made the scholars realize that resorting to physical violence was not a wise move, and in the end, he made them obediently listen to the entire argument.

Then... those astronomers went from anger to contemplation, then to sudden realization, and finally all gave a thumbs up, believing that while this line of thinking was shocking, it at least provided a possible direction for explaining the unnatural coincidences in astronomical observations.

Thinking of that scene, he still finds it a bit funny now.

"What I mean is!"

"In the distant past of our Solar System, there existed more than one civilization. They might have erupted into conflict with each other for reasons unknown to us."

"Of course, it could also be that a native civilization within the Solar System and a civilization from outside the Solar System engaged in a super war!"

"And the main reason for that war was because of [Nuclear]!"

"There is a key point here: Nuclear. Big Brother will tell you later why it must be a nuclear war, rather than a high-tech war!"

Xiaoyu listened with her beautiful eyes wide open.

"But Xiaoyu!"

"To understand why Big Brother has this near-sci-fi conjecture, you must first understand how the astronomical community deduces the formation of the Solar System."

"Accretion model?" Xiaoyu tried to answer.

This is the current mainstream hypothesis in the world, that the Sun was gradually formed by absorbing the initial nebula.

Jiang Zhe nodded slightly and then shook his head. "Where our Solar System came from today, there is currently no direct record. Everything is just people's hypotheses and deductions; there is no single hypothesis that can explain everything."

"Regarding the formation of the Solar System, it actually needs to be traced back to over 300 years ago, in 1755, when a German philosopher, Immanuel Kant, published a work titled 《General History of Nature and Theory of the Heavens》; at that time, he first proposed a concept—the Solar System might have originated from a huge, slowly rotating primitive nebula."

Inside the National Astronomical Institute, Professor Zhang Qinian nodded gently and whispered to the young researcher beside him: "The Nebular Hypothesis. This is our current mainstream view on the origin of the Solar System, and also what is in the textbooks for children."

The young researcher couldn't help but whisper: "Are we still using the framework proposed by a philosopher over three hundred years ago?"

Professor Zhang glanced at him, "Unless you can be like that person on the screen and propose a new hypothesis that is more logically self-consistent, better explains observational facts, and convinces most of the academic community, the Nebular Hypothesis remains the best choice."

The young researcher shrank his neck and didn't speak again.

Inside the villa, in the living room.

Jiang Zhe slowly began: "Kant's idea was that the Solar System was initially a chaotic, misty nebula of matter; under a certain mechanism, such as gravity, it began to condense and contract, and then the Sun formed at the very center; the surrounding disk of matter condensed into planets."

"This idea was very advanced at a time when the Heliocentric Theory was still prevalent!"

"However, his model was more of a philosophical speculation."

"It wasn't until about forty years later, at the end of the 18th century, that a famous French mathematician and astronomer, the Marquis Pierre-Simon Laplace, independently proposed a 《Nebular Hypothesis》 based on mechanical principles."

"Later, the scientific community combined the two, calling it the [Kant-Laplace Nebular Model]."

"However, this model was popular for less than a hundred years before it encountered severe challenges."

Pausing for two and a half seconds, he continued to speak slowly: "The challenges mainly came from observational data."

"First, the Sun's mass is too large; it accounts for over 99.86% of the total mass of the entire Solar System!"

"And all the planets, moons, asteroids, etc., in the Solar System combined only account for that pitiful zero point zero something."

"Secondly, there is the problem of planetary orbits and motion. These contradictions are ultimately concentrated in one key physical quantity—angular momentum."

"Angular momentum?" Xiaoyu said, deep in thought, "I remember a bit, but also forgot a bit."

"Simple!"

"Xiaoyu, you can understand it as how much energy a rotating body maintains its rotation with; it is related to the object's mass, size, and especially its rotational speed."

"For example, an athlete on an ice rink: when she spreads her arms, her rotation speed slows down; when she pulls her arms in, the rotation speed becomes faster; this is the manifestation of the conservation of angular momentum."

Xiaoyu nodded thoughtfully, "Just like a spinning top, the heavier it is, the faster it spins, and the less likely it is to fall?"

"Not bad, very close." Jiang Zhe nodded approvingly, "According to the accretion model of the Nebular Hypothesis—just like rolling a snowball, the massive central celestial body, the Sun, gradually absorbs the surrounding matter and the angular momentum they carry during its formation process."

"Then theoretically, the Sun, which absorbed all the mass, should also possess almost all of the angular momentum; it should be spinning super fast."

Speaking of this, he nodded slightly and held up a finger,

"But the facts are exactly the opposite!"

"The Sun's mass is enormous, but its rotational angular momentum is pitifully small, accounting for less than 0.5% of the entire Solar System's angular momentum."

"And the planets with very small mass account for over 99.5% of the total angular momentum within the Solar System!"

"This means that the Sun, this giant, is almost stationary, while those tiny planets are crazily revolving around the Sun!"

"It's like a fat person standing on the spot, barely moving, while a bunch of little guys run circles around him at super fast speeds, and they carry the vast majority of the rotational energy. Is this reasonable?"

Xiaoyu shook her head subconsciously, "Unreasonable!"

"Yes, it is not reasonable!"

"What's even stranger is that this phenomenon seems to be unique to our Solar System!"

He said this, picked up the tablet, and randomly picked out some other star systems, "Look at other similar celestial bodies, such as failed black holes: neutron stars. The greater their mass, the more terrifying their rotation speed; some can even reach ten or twenty percent of the speed of light!"

"Compare them to other stars in the Milky Way; many that are larger or smaller in mass than the Sun have rotation speeds that are much, much faster than the Sun!"

"Even within our Solar System, this rule is the opposite."

"The larger the planet's mass, the faster it tends to rotate!"

"Jupiter, the largest planet in the Solar System, rotates once every 10 hours; Saturn is 10.5 hours, Neptune is 16 hours, Uranus is 17 hours; they all rotate faster than the 24-hour Earth!"

"In other words, within the Solar System, celestial bodies that have absorbed more mass rotate faster, which conforms to the standard of angular momentum!"

Having told this much, he narrowed his eyes and asked, "Xiaoyu, but why does the rule fail when it comes to the Sun?"

"It essentially absorbed more mass, yet it rotates the slowest!"

"All the angular momentum problems became the fatal blow that negated the early Nebular Hypothesis."

"Later, although there were other hypotheses, such as the capture theory, where the Sun relied on gravity to grab wandering planets from outside; but this capture theory has even more problems!"

"In the end, scientists found that the Nebular Hypothesis still had fewer contradictions; although it cannot explain the angular momentum problem, everyone still uses it as the mainstream framework to this day. Even today, in 2026, astronomers are still looking for reasons to explain this difficulty!"

After he finished speaking, the barrage was silent, everyone was deep in thought.

Although there were no continuous explosions, Big Brother's gentle, storytelling tone made those netizens who didn't like astronomy gradually become interested in it.

"Damn, if I had had Big Brother's eloquence before, would I have hated astronomy?"

"Exactly, my university professor always threw formulas at me; who doesn't know that formulas are the most annoying? Telling stories with analogies is Big Brother's style!"

"Love it, love it!"

"..."

Inside the Qingfeng Temple living room.

Zheng Ming looked at the eloquent Jiang Zhe and nudged Fang Xu with his elbow, "Brother Fang, is he talking nonsense?"

Fang Xu shook his head gently and nodded in approval, "No, what he said is very accurate and concise; this is indeed a key point that truly existed in the history of the development of astronomy."

"The Nebular Hypothesis cannot explain the abnormal distribution of angular momentum. Just like compact celestial bodies like neutron stars, their rapid rotation just highlights how incredible the Sun's laziness is!"

"Even looking at the Milky Way, the Sun's rotation belongs to that particularly slow category among stars of the same mass."

"The greater the mass, the faster it rotates; this is a recognized fact. What he said about it being unnatural, from an astronomical perspective, is valid, and it is correct!"

Upon hearing this, Zheng Ming felt a bit dejected, and his gaze toward Jiang Zhe became even more complex.

Inside Principal Fu's office, the astronomy teacher Ren Xiaoyao frowned. He taught basic elective courses and really hadn't struggled with the contradictions behind the Nebular Hypothesis.

At this moment, hearing Jiang Zhe's systematic analysis, he actually felt a sense of sudden enlightenment mixed with a hint of horror.

Old Yu, who was on the side, saw this and smiled, "Very professional, right? He seems to know a little bit about everything, and it's not just superficial; he can grasp the core contradictions."

"Even if you ask him about human origins, he can talk from paleontological fossils to gene sequencing, and then throw out a few hypotheses that will drop your jaw; he can even make you feel scalp-tingling for days whenever you think about these things. His knowledge base is terrifyingly broad."

Ren Xiaoyao gasped, "I was completely confused by Xiaoyu's question today; I didn't think in this direction at all. I didn't expect her brother, it seems, possibly, to really be able to explain these!"

Just at this moment, inside the big screen.

"Now, Xiaoyu, after knowing the origin of the Solar System, you should have discovered the unnatural aspects that our current mainstream theories cannot explain!"

"Now, here with Big Brother, there is a brand new hypothesis!"

"This hypothesis might be able to explain all the seemingly unnatural coincidences in the Solar System, including the planetary twinning and missing planets you felt, and even the angular momentum that has plagued astronomy for centuries. It can even provide a terrifying possibility: that at least one super civilization once existed within the Solar System!"
