Video spoilers history, starting with the blitzkrieg on Poland

The marquee continues to play.

The shining supercluster of galaxies is constantly magnified.

[Imagine this: All the galaxies on Laniakea's map are like puppets pulled by invisible strings, along the filamentary network of the universe's large-scale structure.]

[Slowly but surely flowing towards the gravitational abyss of the Great Attractor. ]

[Currently, scientists have not yet fully determined the nature of the supermassive black hole.]

[There is a view that the supermassive black hole may be formed by the aggregation of a large number of galaxies and dark matter. ]

[Dark matter is a mysterious substance that we cannot observe directly.]

[But its existence can be inferred through the study of the movement of galaxies.]

[The mass of dark matter far exceeds that of visible matter. It forms a huge gravitational network in the universe, affecting the distribution and movement of galaxies.]

[In the area where the supermassive black hole is located, there may be a large amount of dark matter. ]

[This dark matter interacts with visible galaxies, creating a strong gravitational pull.]

[There is also a view that the supermassive black hole may be a supermassive black hole. ]

[The mass can reach millions or even billions of times the mass of the sun. ]

If the Great Attractor is a supermassive black hole, then its powerful gravity could explain why the surrounding galaxies are attracted to it.

all the time.

Videos related to the universe were very popular among ancient people.

Even Sima Zhong, the foolish emperor of the Jin Dynasty, was like this.

Although Sima Zhong's IQ is lower than that of ordinary people.

But Sima Zhong's interest in cosmic astronomy videos is higher than that of ordinary people.

Sima Zhong sat on the dragon throne, his eyes fixed on the introduction of the giant jet generator on the sky.

My already confused mind was now even more of a mess.

He scratched his head and couldn't help muttering, "What kind of new thing is this giant attractor?"

"I heard them say before that there are black holes in the universe, and now there's a giant black hole?"

“And you still say that the Great Attractor is a black hole?”

"I have an illusion that people in later generations encountered things they did not understand when studying the universe."

"Just throw them all onto the black hole."

"When you are in doubt, go to the black hole?"

And next to Sima Zhong.

The regent Yang Jun was also reminded by Sima Zhong.

"That being said, it seems true."

“Many sky-screen videos in later generations mentioned black holes when talking about things in the universe.”

“Is this giant black hole a black hole?”

And amid the ancient people's doubts, curiosity and complaints.

The sky curtain also continues.

[Now, we seem to have a preliminary understanding of the supermassive black hole. ]

[But there’s a troubling paradox here: According to the theory of cosmic expansion, all the galaxies should be moving away from each other, driven by dark energy.]

[However, within about 3 million light-years around the supermassive source, Hubble's law seems to fail.]

[Countless galaxies are swimming upstream, fighting against the tide of cosmic expansion.]

[This suggests that beyond observable matter, there must be some distribution of matter or form of energy that we have not yet understood.]

[Some theories suggest that the Great Attractor may be the core of a dark matter continent spanning 4 million light years.]

[Its mass may be more than ten times that of visible matter.]

[What’s even more amazing is that the supermassive black hole itself is also moving! ]

[The latest research shows that all matter, including the Laniakea Supercluster. 】

[Actually, they are all moving towards another larger source of gravity! ]

[The Great Attractor is moving towards the location of the Shapley Supercluster at a speed of 1600 million kilometers per hour, carrying all the galaxies it attracts.]

[This behemoth, called the "Shapley Supercluster," is about 6.5 million light-years away from us. ]

[It consists of more than 8000 galaxies, and its gravitational influence extends to more than 400 galaxy clusters! ]

[Its mass is at least 1000 billion billion times that of our solar system! ]

[So the whole picture becomes a gravitational nesting doll. ]

[The Milky Way is pulled by the Great Attractor, which is pulled by Shapley.]

【And Shapley? 】

[Perhaps it is also being pulled by a more distant unknown structure...]

[This nested network of gravity outlines a grand picture of the large-scale structure of the universe.]

[Some scientists believe that this force that drives the movement of galaxies is very likely related to the expansion of the universe and is inextricably linked to dark energy.]

[However, unfortunately, it is limited by the current level of technology. ]

[We have absolutely no way of observing what is happening in this mysterious area.]

【We can only make inferences based on existing scientific discoveries. 】

【As we approach the supermassive black hole, we will eventually enter its area of ​​jurisdiction. 】

[Is this the final destination of all galaxies? ]

[Will our destiny end here as well? ]

[But don’t worry, this migration across the cosmic scale will not lead to a direct collision of galaxies.]

[Due to the expansion of the universe, the Milky Way may never actually reach the supermassive black hole.]

[Like an ant crawling on the surface of an inflated balloon.]

[Although we keep moving forward, the goal is accelerating away from us. ]

[According to calculations, about 1300 billion years from now, when the expansion of the universe dominated by dark energy completely tears apart the existing galaxy structure.]

[The gravitational influence exerted by the Great Attractor may become the last cosmic memory of this dark age.]

So where do we go from here?

[The answer to this question may be hidden in those dark areas of the universe that have not yet been penetrated by electromagnetic waves. ]

[In the dark matter that makes up 85% of the mass of the universe but never emits light. ]

[In the dark energy that drives the accelerated expansion of the universe. ]

[Beyond the boundaries of human cognition, there is always a greater unknown. ]

【And it is this unknown that makes every night when we look up at the stars. 】

【All filled with shock and awe! 】

The sky screen video ends here.

Barrages of comments flew out one after another.

"The universe is so scary!"

"Every night I get pushed videos about the universe, but after watching them I just feel extremely empty."

"When I was a kid, I thought it was popular science, but now I think it's depressing. The end of everything is nothingness."

《Human beings are nothing.》

《I'm so scared, what should I do then? 》

"When I get to Earth, I will be sucked in by the supermassive black hole. I will be so uncomfortable that I can't sleep. My future will be dark!"

"The Great Attractor may be the entrance to the upper world."

《Sun: Children, follow me! Let’s go to the center of the Milky Way!》

"Milky Way: Children, follow me, let's go to the center of the supermassive black hole!"

"It can't be a black hole anyway. If it is a black hole, then this black hole may be larger than the entire Milky Way. There can't be a black hole that big."

"The Great Attractor is a combination of a bunch of supermassive black holes."

"It feels like this gravity is an infinite nesting doll."

"Change a map to the top, and you will immediately find that there are even more awesome areas."

"Great! I'm going to see the supermassive black hole during the first day of the New Year holiday."

While netizens were discussing it.

tomorrow.

Xu Guangqi stood under the sky, watching the introduction about the supermassive black hole intently.

Xu Guangqi, who had a strong interest in astronomy, could not help but say with regret:
"It turns out that there is such a mysterious and powerful existence in this world!"

"I have devoted myself to studying the mysteries of the universe, and although I have gained some insights, they are insignificant compared to the mysteries of the universe revealed by this sky."

"This giant attractor can pull in countless galaxies. Its power is beyond imagination."

"What are the court disputes and trivial matters that we usually pay attention to in the face of this vast universe?"

"I really want to concentrate on studying knowledge!"

"Now with Tianmu's assistance, I, Xu Guangqi, should be able to research knowledge more effectively than before."

"Unfortunately."

Xu Guangqi sighed again.

"The Ming Dynasty is now facing internal and external troubles. As a minister, I should do my best to assist them, wipe out the rebels and Tartars, and bring peace to the people."

"But when all this is over, I will resign from my post and devote myself to this vast scholarship."

"And now, let's look at what we have learned through the Sky Curtain."

"How can we save the Ming Dynasty from this crisis?" (End of this chapter)
