Video spoilers history, starting with the blitzkrieg on Poland

The new sky appeared with melodious and soothing background music.

In the vast universe.

The sky screen video begins to explain.

Where are we going?

[This question seems to be the eternal philosophical question of human civilization. ]

[But today, please forget about philosophy and poetry for a moment - let us turn our gaze to the starry sky above our heads. ]

[This is the diagram of the solar system we see in books. They are almost running on one plane.]

[But this is actually how it moves.]

[It moves in an almost spiral fashion.]

[Our sun is running wildly in the universe with the entire solar system at a speed of 220 kilometers per second.]

[The Milky Way itself is madly rushing towards an unknown coordinate deep in the universe at an astonishing speed of 600 kilometers per second...]

[Such a fast speed. ]

Where is the sun taking us?

[And the end point of all these movements may be hidden in the cosmic mystery called the Great Attractor. ]

【To understand this interstellar migration spanning hundreds of millions of light years. 】

【We must first re-recognize our position. 】

[The solar system where the earth is located is like a pearl inlaid in the Orion spiral arm of the Milky Way. ]

[When you look up at the Milky Way on a clear summer night, you'll see the milky white band of light that stretches across the sky. ]

[It is the city in this galaxy with a diameter of 10 light years that we are in. ]

But the city is far from static.

[The entire Milky Way is like a huge cosmic windmill, with all the stars rotating around the black hole at the center of the Milky Way. It takes 2.3 million years to complete one revolution.]

[This movement of the solar system is not isolated; it is also affected by the distribution of surrounding celestial bodies and matter.]

[On a larger scale, we can observe the movement of the solar system within the Local Group of galaxies.]

[The Local Group includes about 50 galaxies including the Milky Way and the Andromeda Galaxy. ]

[These galaxies interact with each other through gravity, forming a relatively stable celestial system. ]

[The Milky Way is moving towards the Andromeda Galaxy at a speed of about 300 kilometers per second.]

[Scientists predict that in about 40 billion years, the Milky Way and the Andromeda Galaxy will collide and merge. ]

【This will be a grand event of cosmic proportions. 】

[However, astronomers discovered a strange phenomenon in the 1970s.]

【After we accurately deduct the rotation of the Milky Way. 】

[The Local Group, including the Milky Way, the Andromeda Galaxy and 54 other galaxies, is still moving towards the Centaurus at an inexplicable speed. ]

【It's like boating on a calm lake.】

[Suddenly I realized that all the ships were being pushed in the same direction by the undercurrent - there must be some source of gravity that we can't see.]

[This mysterious source of gravity is the Great Attractor. ]

[In 1986, scientists made an amazing discovery in the direction of Centaurus.]

[An extremely strange scene appeared there.]

[There are not only many ancient galaxies distributed in the direction of Centaurus,]

[More and more galaxies are converging towards this area. ]

[These celestial bodies collide with each other, releasing a large amount of electromagnetic radiation and triggering the agitation of gravitational waves. ]

[Even more amazing is our own Milky Way galaxy and all the galaxies within hundreds of millions of light years of the Milky Way.]

[As if driven by an invisible force, it rushed towards this abnormal area like a surging river.]

[Scientists named this region of gravitational anomaly the Great Attractor.]

[The supermassive black hole has a terrifying mass. ]

[The gravitational force generated makes it difficult for almost all galaxies to resist. 】

[According to current trends, in about billions of years, most of the galaxies in the galaxy cluster where the Milky Way is located will be attracted to the vicinity of the supermassive black hole.]

Outside the sky.

The ancients were shocked.

Through the sky videos during this period, the ancients already knew how huge the Milky Way was.

What an exaggeration.

But now Tianmu says that the Milky Way is being led?
Spring and Autumn.

Confucius stood under the Xingtan where he gave lectures, gazing at the introduction of the Great Attractor.

"My disciples, look at this universe. It is so vast and boundless."

"That giant attractor pulls in countless galaxies. Its power is beyond imagination."

Zengzi, who was standing beside him, replied respectfully: "Master, this is indeed shocking."

"What caused it? Could it be the Son of Heaven?"

"If there is a powerful force in the sky pulling, does it mean that there should be a powerful monarch on earth as well?" I heard this guess.

Although Confucius felt that it was inconsistent with the facts.

But Confucius found it very interesting.

After thinking for a moment, Confucius said:
"No! Zhou Li emphasizes that everyone should be content with their own position. The stars have their own orbits, just like a gentleman should abide by his duties."

"If there is an emperor in the universe, each star system should follow its own path."

The students standing by also expressed their views.

"Master, we understand."

And Tianmu also began to formally introduce the supermassive black hole.

[So, now we can talk about what a supermassive black hole is. ]

[The Great Attractor is a gravitational anomaly located near the center of the Laniakea Supercluster.]

[The Laniakea Supercluster is itself a huge celestial structure. ]

[It contains about 10 galaxies and has a diameter of 5.2 million light-years.]

[And the supermassive black hole, like the heart of this supercluster, dominates the movement of many galaxies inside. ]

【After twenty years of observation and calculation. 】

[In 1986, scientists finally locked down the coordinates of this mysterious gravitational force: it lurks in the direction of the Hydra-Centaurus Supercluster, about 1.5 million to 2.5 million light-years away from Earth.]

[This existence, named "the Great Attractor", has a mass equivalent to tens of thousands of Milky Way galaxies. ]

[The gravitational force generated is enough to drag galaxies within hundreds of millions of light years towards it. ]

[Including our own Milky Way galaxy.]

[But the true face of the supermassive black hole is still shrouded in mystery. ]

[Because it happens to be located in the hidden zone of the Milky Way's disk. ]

[The occult zone is a barrier of densely populated areas of interstellar dust and stars.]

【It blocks the observation of the Earth's visible light band. 】

[Our most important telescopes are nearly blind in this direction.]

[It was not until the beginning of the 21st century that astronomers began to use infrared and radio waves with stronger penetration power, and only then were they able to glimpse the tip of the iceberg of the giant black hole.]

[Data shows that this gravitational monster is likely the core of the Norma galaxy cluster. ]

[There are hundreds of ancient galaxies gathered there, with a total mass of about a quadrillion times that of the sun.]

[But here’s the puzzling part: Even if you take into account all the visible matter in the Norma Cluster, its gravity is still not enough to explain the observed velocities of the galaxy streams.]

[This means that there may be even more shocking secrets hidden behind the supermassive black hole.]

In 2014, when scientists mapped the boundaries of the Laniakea supercluster.

【The true status of the great attractor is finally revealed. 】

[This cosmic structure, with a diameter of 5.2 million light years, includes 10 galaxies, including the Virgo Supercluster! ]

[And the Great Attractor is the gravitational center of the entire supercluster! ]

The sky screen now gave a picture.

This is the picture of the Laniakea Supercluster!

This picture, full of the majestic power of the universe, is bright and shining.

It's like a huge collection of filamentary structures in the universe.

The numerous galaxies are like sparkling gems inlaid in these filamentary structures.

Against the backdrop of the vast dark universe, bright galaxy concentrations are intertwined to form an irregular network.

There is also relatively empty space in between.

Even though it's just a picture.

But it is full of great power.

It makes people feel extremely beautiful and shocking!

Even the ancients had seen the magnificence of the universe many times through sky dome videos.

But at this moment, I couldn't stop being shocked!
Northern Song Dynasty.

Shen Kuo looked at the unprecedented picture of the Laniakea Supercluster on the sky and couldn't help muttering to himself:
"Is this... is this the vastness of the universe?"

Shen Kuo's eyes were filled with shock and he shook his head slightly, his heart filled with regrets about his own insignificance.

"Such a huge galaxy cluster contains countless stars, and the world we live in is just like dust in it."

"The ancients often said that the world is vast and boundless, but compared with what is revealed by this canopy, it is really nothing."

"The Laniakea Supercluster is so vast that even if we use our imaginations, we still cannot measure its boundaries."

Although Shen Kuo was in shock and EMO.

But the pen in my hand did not stop.

“Although the universe is huge and the superclusters are endless, they can still be contained in my pen.”

"record it."

"I believe that the wisdom of future generations will answer this question for us." (End of this chapter)
