92: Chapter 92: I asked you to give examples, not to reveal the secrets of cosmic reincarnation.

Upon hearing about the "super singularity" and just how absurd it could be, the viewers in the livestream room immediately had their imaginations run wild.

"No matter how absurd, as long as you can think of it, it can appear?"

"So if I think about lying flat and getting rich every day, that can be realized too?"

"The person above has too small a perspective. I want alien fleets to rule Earth, as long as they give me a nine-to-five job, two days off a week, and insurance."

"Non-kin, their hearts... are also good. If the money is enough, Earth can be sold too."

"So, dinosaur resurrection, human evolution, even things in fantasy stories—as long as someone can imagine them and make them self-consistent, will the future leave a place for this idea?"

"Isn't this world a bit too idealistic?"

"..."

One idea, and it can be realized in the future no matter what?

Xiaoyu, stealing a glance at the screen to read the barrage comments, couldn't help but laugh. She looked at her older brother with burning eyes: "Older brother, no matter how absurd, what about a spaceship that travels through time?"

"That definitely couldn't appear, right? After all, time cannot flow backward."

Jiang Zhe, however, had a look of wondrous amusement: "You even thought of this? It definitely can appear!"

"This can appear too?" Xiaoyu felt it was unbelievable. "No way, no matter how the future is, it wouldn't have time-travel means, otherwise we would have seen traces of future people in the present or ancient times."

Jiang Zhe shook his head slightly, refuting this: "Based on current fundamental laws of physics, the arrow of time flows forward, only forward; the time-traveling spaceship you mentioned might not be fantasy in that scenario!"

"Really possible?"

"Yes!"

Watching Xiaoyu's eyes flicker, Jiang Zhe seemed to have grabbed hold of her curiosity and continued:

"I've talked about the grandfather paradox before: a grandson in 2025 killing his grandfather in 1980."

"It is indeed achievable."

"What does the grandson need? A time machine that reverses time? No, not needed."

"He only needs a spaceship that can approach the speed of light infinitely!"

"Future interstellar spaceships will definitely be equipped with energy shields to resist tiny obstacles in outer space during high-speed flight."

At this moment, the viewers were confused. We asked you to make the spaceship travel through time, not approach the speed of light!

"A spaceship infinitely approaching the speed of light?" Xiaoyu's beautiful eyes flickered. "Doesn't that only allow travel to the future? You can't go to the past, right?"

Jiang Zhe spoke slowly: "As for whether it's possible, you'll know after listening."

"Assume the grandson gets on that spaceship and starts accelerating crazily. As the speed infinitely approaches the speed of light—"

"The grandson's time relative to the outside world will slow down drastically. This is internal and external relative time dilation."

"In the grandson's eyes, the starry sky outside the spaceship will rapidly turn into light particles, stretch, everything will start to shrink, and then his vision will fall into total darkness—because the speed of light, 300,000 kilometers per second, cannot catch up to the grandson's spaceship."

"At the same time, outside on Earth, time is passing at an inhuman speed—"

"Civilizations rise and fall, the Sun extinguishes, the Milky Way dies, until the universe meets its end, heat death, and finally the Big Crunch."

At this moment, in the lounge at Huaqing University.

Dr. Li Mo gasped sharply, unable to help but be shocked by Jiang Zhe's rhapsody.

Professor Guan narrowed his eyes, as if he had rediscovered how magical Jiang Zhe was: "His ideas are based on physics; you can basically find no fault with them. He is different from those other people."

Jiang Zhe's voice came again.

"Next, after the universe ends, if it really follows the Big Bang theory—then after the universe dies, it will re-contract."

"At that time, it will refocus into a [giant singularity], and finally, with a [bang]!, the universe will explode again."

"At that time, for the grandson in the light-speed spaceship, his own time is almost static, unaffected by the Big Bang or the Big Crunch."

"In just a few days, or even a few dozen days, within his own state on the light-speed spaceship, he directly [jumps] over the billions of years of the universe's demise and arrives directly at the beginning of the [next] newborn universe."

"In the new universe, time begins to flow, and the Milky Way, Solar System, and Earth begin to evolve again."

Finishing his explanation, seeing Xiaoyu's beautiful eyes widened in realization, Jiang Zhe smiled slightly: "Xiaoyu!"

"The grandson finally stops in 1980 on Earth and kills his grandfather."

"Logically speaking, the grandfather's death didn't affect the grandson, right? And this is a scientific law, under the premise that time is irreversible!"

"Nowadays, we don't even need to violate causality. We just need to stretch the length of time enough, and returning to the past can be self-consistent from that perspective."

"Of course, such materials will appear in the future, but it will take a very, very, very long time!"

"So your idea will definitely be realized!"

Xiaoyu was already dumbfounded, her scalp tingling. After a long while, she squeezed out a sentence:

"Brother, I was just asking about a time machine casually, and you actually have a solution?"

Jiang Zhe, of course, wouldn't say... this was just the most low-level and basic method among the think tanks in his previous life.

At this moment, the viewers were almost going crazy!

"Holy crap, I'm speechless!"

"Is such a hardcore [possible] allowed? The key is that it sounds like there's no problem!"

"Brain: I understand. Hands: No, you don't!"

"Damn, brother, do you have a misunderstanding of fundamental laws? You call this fundamental laws?"

"Understood. Need a spaceship, then accelerate to the speed of light, and live to the next cosmic era. Farewell!"

"..."

In the Huaqing University lounge.

Everyone was silent, all seeing excitement on each other's faces.

Li Mo gasped, looking at Professor Guan, somewhat incredulous: "Although it's crazy, in the eyes of [a madman with unorthodox methods], these are indeed the most scientific..."

Professor Guan couldn't help but applaud him: "It seems we didn't come to the wrong place tonight. Those concepts are really being thrown out by him anytime, anywhere. He is not human!"

On screen.

Jiang Zhe looked at Xiaoyu's dumbfounded expression and smiled, pulling the topic back.

"Do you understand now?"

"Anything that can be imagined, even the absurd kind I just mentioned, in the infinite possibilities of the future..."

"It will all appear, and it will all have its place!"

Xiaoyu suddenly had a brain flash: "Brother, you mentioned the Big Bang, cosmic collapse, and the universe re-exploding to generate a new universe... Oh my god, the universe is like a black hole. My teacher said black holes will eventually evaporate; will the universe eventually evaporate too?"

Jiang Zhe narrowed his eyes inexplicably, then the corners of his mouth curled up slightly:

"Yes. This involves astronomy, and there is too much to talk about here; there are many interesting things. We'll talk about it later."

"Let's withdraw these impractical fantasies and focus our vision on reality."

"Brother will help you sort out the historical singularities that have already happened on Earth, as well as the super singularities that will impact human civilization in the near future!"

At this moment, countless viewers straightened their backs, holding their breath.

"Now, let's magnify this concept of a singularity."

"Putting it on Earth itself, its birth is the biggest singularity!"

"Then, 4.2 billion years ago, the birth of life: How did inorganic matter form organic matter capable of self-replication? Don't know, singularity."

"550 million years ago, the Cambrian explosion: Why did simple cellular organisms suddenly evolve into the prototypes of almost all modern animals in a short geological period? Incomprehensible, singularity."

"330 million years ago, the appearance of reptiles, singularity."

"200 million years ago, the birth of mammals, singularity."

"80 million years ago, the birth of primates."

"Then 3.9 million years ago, Australopithecus, started walking upright—why? Just because of the environment, or some kind of drive? Modern times are still full of mysteries, singularity!"

"1.8 million years ago, humans systematically started using stone tools—from using natural tools to making tools, this is a leap in human [cognition], belonging to a singularity!"

"10,000 years ago, the Agricultural Revolution—humans suddenly shifted from hunting and gathering to planting and animal husbandry, their lifestyle completely overturned and changed, singularity!"

At this moment, in Qingfeng Temple.

Zheng Ming couldn't help but shake his head when he heard this:

"I admit his physics level is extremely high, but this is still too far-fetched!"

"These are just long processes with traces to follow. How can they be considered singularities? It's completely forced!"

This time, Celestial Master Zhang did not correct him.

He just listened silently, seemingly considering what this had to do with the Dao.

On screen.

Jiang Zhe happened to answer this question:

"Xiaoyu, if you look back with today's perspective, the emergence of agriculture is very natural—it's the result of slow development."

"But if you stand from the perspective of that tribesman 10,000 years ago and look at it."

"Can you imagine stopping your footsteps, starting to bury wild grass seeds into the soil, and then waiting months to harvest the fruits of the wild grass?"

Xiaoyu nodded repeatedly, not refuting this time.

Not only Xiaoyu, but the viewers listening carefully also gradually understood what a singularity was!

"Xiaoyu,"

"You will find that the previous singularities were hundreds of millions of years, then tens of millions of years, then millions of years, tens of thousands of years, until 10,000 years ago."

"The outbreak of singularities was very slow at the beginning, but as time passed, the speed of the outbreak became faster and faster, faster and faster!"

"In the blink of an eye, it became a few hundred years. About 250 years ago, the Industrial Revolution."

"Before steam engines replaced manual labor, who among the emperors, monarchs, scholars, and craftsmen of the feudal era could imagine a type of large power machine that did not rely on human, animal, wind, or water power, but could liberate hands and output continuously?"

"This is a singularity in the field of productivity."

"More than 130 years ago, the telephone appeared, making remote voice communication possible."

"70 years ago, electronic computers were completely born!"

"In recent years, big brother phones, keypad phones, screen phones; the iterations accelerated after these appeared; but the moment before they appeared, they all brought people a sense of shock. This is a small singularity."

Looking at Xiaoyu, Jiang Zhe concluded:

"According to my sorting and observation, after humans entered a technological civilization, these [technological singularities] that change the rules of the world appear with increasing frequency, and the time intervals are becoming shorter and shorter;"

"Our technology curve is not a uniform line, but..."

Speaking of this, he casually took out paper and pen from the pocket of his black trench coat. Relying on the small streetlights in the park, he drew a line on it that started flat, then gradually became steep, and finally vertical, and finally wrote down the relevant years.

"It is growing exponentially!"

He handed the paper to Xiaoyu. Xiaoyu observed the year table on the paper; it was indeed getting faster and faster, just as her brother said, from hundreds of millions of years to tens of millions, millions, tens of thousands, thousands, hundreds, tens, a few years...
