Video spoilers history, starting with the blitzkrieg on Poland

And the sky continues.

[Except that the world is virtual.]

[Even if the world is absolutely real. 】

[From the perspective of civilization development, if there are no aliens in the universe, that is definitely not good news. ]

[Because this may indicate that the birth and development of civilization faces a huge bottleneck. ]

【On Earth, the development of human civilization has gone through countless challenges. 】

【From natural disasters to disease epidemics, from resource scarcity to war conflicts. 】

[We have only developed for a few thousand years, but we are already facing many crises that may lead to the destruction of civilization, such as environmental destruction and nuclear threats.]

[From amino acids in the primordial ocean to interstellar civilization, each species must go through multiple evolutionary levels:]

[Nuclear fusion, artificial intelligence, interstellar travel...]

[And 99.99% of civilizations will be wiped out at some stage. ]

[If there are no other civilizations in the universe, it means that in the entire history of the universe, almost no civilization can break through these bottleneck stages! ]

【This is the Great Filter Theory.】

[It is almost impossible for civilization to break through these key links. ]

[Almost all of them will be stuck at the critical node and die. ]

[The most terrifying thing is not that we have passed all the tests, but that we have discovered the remains of a civilization that has been completely destroyed at the checkpoints ahead.]

【Dyson spheres swallowed by black holes. 】

[A space city that vaporized due to antimatter going out of control. ]

[All of these suggest that humanity may be standing on the brink of the guillotine. ]

It’s like a big filter.

[This is undoubtedly a huge warning to mankind. ]

[It is very likely that we will not be able to escape these crises, and civilization may end at any time. ]

[Let’s think about this from another theory that makes people shudder: the Dark Forest Principle. ]

[This law comes from the novel "The Three-Body Problem" by Chinese science fiction writer Liu Cixin.]

【It compares the universe to a dark forest.】

【All civilizations are hunters and prey lurking in it. 】

[In this forest, every civilization must hide its whereabouts. ]

[Because once exposed, they may be attacked by other civilizations. ]

【What if there are no aliens in the universe? 】

[That means that all civilizations have successfully hidden themselves. ]

[Or all civilizations have perished before they were exposed. ]

[The former situation means that the universe is full of extremely dangerous unknown civilizations. ]

【They all adhere to the law of the dark forest. 】

【Always be alert to the emergence of other civilizations. 】

[Once discovered, they will be destroyed without hesitation. ]

[The latter case shows how fragile the survival of civilization is.]

【If you are not careful, you will be destroyed. 】

[The Milky Way has existed for 130 billion years. Even if a civilization evolved only 100 million years earlier than humans, they should have used Dyson spheres to wrap stars and use gravitational waves to broadcast cosmic declarations.]

[But the reality is that even the sophon detector in "The Three-Body Problem" has never appeared. ]

[This eerie silence is more chilling than any alien warship - perhaps all civilizations have been wiped out by some unknown force, and humans just happened to be on the countdown to extinction. ]

[No matter which situation it is, it is chilling. ]

【and.】

[Assuming there are no aliens in the universe, then humans are alone in the universe. ]

This loneliness is not just emotional.

【It is also a deep worry about the future. 】

[We have no one to communicate with or learn from, and we don’t know how other civilizations develop technology, solve social problems, and deal with cosmic crises.]

【We can only grope our way forward alone.】

[When faced with major problems, there is no experience from other civilizations to draw on, and no allies to rely on. ]

[Moreover, when we send signals into the depths of the universe and expect a response, we never get any feedback.]

[This silence seems to be the universe's indifference to humans. ]

[It makes people feel extremely small and helpless. ]

【The universe is so vast that the possibility of life existing in theory is extremely high. 】

【But we still haven’t found any trace of aliens. 】

[If there are really no aliens in the universe, it would mean the extreme uniqueness of the Earth, the difficult bottleneck of civilization development, the terrifying universe environment under the law of the dark forest, and the lonely and helpless future of mankind. ]

[In comparison, the existence of aliens may make us feel a little more at ease. ]

[Because it means that life is not unique. ] [The development of civilization is not hopeless. ]

[So, the most terrifying thing is that there are no aliens in the universe. ]

【but. 】

[The silence of the universe may be the highest level of alarm, but it may also be the most generous opportunity. ]

[Even if the entire universe is a testing ground. ]

[Also let alien observers keep this in mind. ]

Our Earth Civilization.

[The brightest light ever bloomed! ]

The sky screen video ended here, and barrages of comments flew out.

"It's normal to think that aliens exist. It's not unreasonable."

"With a universe of tens of billions of light years, Earth is the only one exploring alone in the darkness. Just thinking about it makes me feel lonely and sad."

"If there were no aliens in the universe, the Earth would be extremely lucky. I am the King of Luck."

《It doesn’t matter whether it’s fake or not.》

"As long as it's true to humans, it's fine."

"Perhaps all aliens will become extinct before leaving the galaxy."

"The vast majority of civilizations, from birth to extinction, may not be able to leave their own star system."

"The Big Filter sounds pretty plausible."

"There are already traces of the Great Filter on Earth: the Aztec civilization of the American people, who were stuck in the Stone Age forever, because America lacked easily mined iron ore. So does interstellar travel require special resources? If so, humans will never be able to break through."

"I hope it's not a dark forest."

"The Dark Forest is unreliable at first glance."

"The premise of the Dark Forest Law is that there are indeed a large number of civilizations in the universe itself."

"Aliens may not care about us, just like you would not care about an ant in front of you."

"Even if aliens discovered the Earth, they wouldn't have enough gas to come here once, and they wouldn't be able to endure a journey of tens of thousands of years!"

"From a probabilistic point of view, it is quite possible that humans are the first civilization in the universe."

"Someone will win, so why can't it be a human?"

"Is it possible that there are a lot of aliens, but humans are not high enough to join the group chat?"

"The universe is too big to find aliens. We just haven't reached that level yet."

"The greatest tragedy of the universe is that the speed of light cannot be exceeded, and the universe is too big."

Netizens were discussing it enthusiastically.

The same was true for the ancients.

Qin Dynasty.

Ying Zheng watched the video with a keen eye, listened to the three theories, and just sneered indifferently.

"This virtual universe theory says that we are in an illusion?"

"Humph, every inch of land and every citizen of my Great Qin are real and tangible. How can they be illusions?"

"As for the Great Filter Theory, if there really is such a bottleneck that hinders the development of life, my Great Qin will also break through it."

Ying Zheng paused again.

“As for the Dark Forest Theory?”

"That's interesting."

"If the universe is really as this theory says, it is a dark forest full of dangers."

"Then I will make Daqin even stronger."

"Including the descendants of the Chinese people in the future, we must also make our civilization strong!"

"In this cosmic jungle, only the strong can survive."

"We must make China the overlord of the universe, so that other civilizations, if they exist, will not dare to underestimate our Great Qin, and will not dare to spy on China!"

The ministers around him applauded Ying Zheng one after another.

And Ying Zheng also said firmly at the end:

“Whether it’s the bottleneck of the big filter or the hidden dark forest.”

"Humanity must move forward at all costs!"

"Only when it's strong enough will humans have a choice."

And in the Song Dynasty.

Song Huizong was too lazy to think about so many unnecessary things.

I just looked at the sky and wrote on the blank space on the paper:
"The green mountains and rivers are the palette of the Creator, and my brush and ink are the truth."

“What if we really find out in the future that the world is fake?”

"But at least my artistic creations will amaze the aliens!" (End of this chapter)
