Chapter 352: The most terrifying celestial body in the universe, not inferior to a black hole?
And the new sky soon appeared.

【One of the most terrifying celestial bodies in the universe. 】

[It is small in size, but extremely massive. ]

[A neutron star with a diameter of 10 kilometers has a mass far greater than that of the sun! ]

[And if a neutron star the size of a stadium collides with the Earth. ]

[Then the Earth will be crushed to death without a doubt! ]

[And the extremely high mass is just one of the many terrifying characteristics of neutron stars. ]

[In the next video, we will reveal what a neutron star is. ]

[And why is it that neutron stars are called one of the most terrifying celestial bodies? 】

The first few sentences of Tianmu attracted the curiosity of many ancient people.

Long before the sky appeared, ancient people often looked up at the starry sky and pondered the mysteries of the universe.

And since the sky curtain appeared, it has told stories about the universe through many passages.

It also allowed many ancient people to establish a preliminary understanding of the universe.

Although it is not a systematic study through textbooks.

I only have a superficial understanding through some videos.

Therefore, the universe in the minds of many ancient people was still imperfect.

His level of understanding is not even as good as that of an ordinary primary school student today.

But many ancient people already knew some basic common sense.

Just like the horror of outer space.

Now, Tianmu said there is a celestial body called a neutron star, which is extremely dense and very terrifying.

The ancients were also very curious.

And look forward to it.

Because neutron stars have appeared in the sky before.

However, that section of the sky mainly tells how gold was produced.

Neutron stars were only mentioned briefly.

The ancients only knew that there was such a celestial body as neutron star.

And know that it seems to be very powerful.

But the ancients could only guess about more specific contents.

And I was thinking: "Can we artificially synthesize neutron stars to produce gold..."

And now, see the sky curtain specifically about neutron stars.

Naturally, people are more interested in the golden planet.

tomorrow.

Zhu Di had just returned from the compilation site of the Yongle Encyclopedia.

As a result, we saw the sky curtain about neutron stars again.

I also looked at it seriously and pondered it.

perhaps?

The content about the neutron star sky can also be written into the Yongle Encyclopedia.

Anyway, ever since the sky curtain appeared.

There is an additional section in the Yongle Encyclopedia that is used to record knowledge related to the sky curtain.

Above the sky.

The sky first showed a dark blue, faintly glowing, rapidly rotating spherical model.

This is the model of a neutron star.

【Neutron star.】

【It is one of the densest celestial bodies in the universe. 】

[Its terrifying degree can even be compared with a black hole. ]

[Although black holes are extremely terrifying, they are relatively stable. ]

【The changes in the properties of neutron stars are obviously more active.】

[The unknown terror that a neutron star can bring is also extremely powerful! ]

However, this part of Tianmu's story obviously aroused the disapproval of many barrage masters.

"It's so funny, a black hole beats a neutron star!"

Quasar: What are you talking about?

"Black Hole: I look at neutron stars like putting a bid to sell Seoul."

"How is that possible? Black holes are much stronger than neutron stars, you know?"

"If the neutron star continues to shrink, it will become a black hole."

……

Obviously, the host made the neutron star sound so terrifying that it can even be compared to a black hole for the sake of publicity.

This statement, which subverts common sense, is indeed very controversial.

It's like the Three Kingdoms period.

After Lu Bu's death, everyone is Lu Bu.

In the movie, all kinds of dinosaurs beat the Tyrannosaurus Rex.

In cosmic videos, many celestial bodies are compared to black holes.

The ancients, because they had read some content about black holes before.

So we basically know that black holes are one of the most powerful celestial bodies in the universe.

So when the ancients saw this, they had the same doubts as modern audiences.

Can this neutron star really be compared with a black hole?
How strong is it?

[There is a line in a movie that goes, "To create, you must first destroy."]

[The origin of neutron stars also comes from the destruction of another massive celestial body. ]

【That is a star.】

[In a sense, neutron stars are stars after they die.]

【After the death of a massive star. 】

[The relics left behind are neutron stars! ]

[Stars continue to emit light and heat during their life cycle and maintain a high degree of stability.]

【It actually comes from a balance of interaction. 】

[The main part of a star is extremely hot and has a huge mass.]

[A large amount of matter is constantly moving toward the interior of the star due to the star's gravity.]

[A huge amount of matter gathers together in a star, squeezes each other, and forms nuclear fusion.]

【Those who often use hydrogen bombs know this. 】

[Nuclear fusion also produces enormous amounts of energy.]

[These extremely huge nuclear fusion energies are released from the inside out. ]

[In this way, a balance between internal and external forces is formed.]

[It can maintain the stability of stars for a very long time. ]

【This form is very permanent and stable. 】

[The name of the star comes from this stability. 】

【But we know that nothing can last forever. 】

【Not even the universe itself. 】

[As the hydrogen inside the star is exhausted, the star will also enter the end stage of its life. ]

[Most stars, including the sun, will first enter a period of rapid expansion.]

[The final result of the expansion will be a white dwarf. ]

[The lifespan of a white dwarf is longer than that of a normal star, almost reaching the same level as the lifespan of the universe.]

[And we know that there are many more superstars. ]

[These larger and more massive stars will have different endings after they enter their final stages.]

[First, the helium inside the star is exhausted. ]

[The balance of gravity from inside to outside and from outside to inside will be broken. ]

[The core of the star continues to condense, and the outer part of the star will rapidly expand to hundreds of times more. ]

[In this process, stars will also continue to generate heavier elements at a terrifyingly high speed.]

[For example, it takes hundreds of years for carbon to turn into neon. ]

[The final process of silicon turning into iron only takes one day.]

[From the perspective of the universe, this is an almost unbelievably short process.]

[When it comes to the iron element, the fusion process is complete. ]

[At this point, since it can no longer undergo drastic changes, the star's gravity begins to compress inward uncontrollably.]

[The entire core of the star will be squeezed and collapsed rapidly. ]

[Since these stars are extremely large and have terrifying masses, the gravitational force from the outside to the inside is also very huge.]

[The pressure from outside to inside is increasing. ]

【And it keeps accelerating.】

[It will cause the matter inside the star to be further squeezed toward the core of the star. ]

[The core of the star is heated at an increasingly faster rate.]

[During the process of extremely rapid contraction, extremely high temperature and high pressure will form inside the star. ]

[Electrons and protons will be further compressed into neutrons. ]

[The core of the star will also be compressed to the extreme. ]

[Generally speaking, the core of a star is more massive than the Earth.]

[But after compression, the core of the star will be only about 10 kilometers in size.]

[At the same time, the entire star will explode violently! ]

[A large amount of matter will be attracted inward at a speed one-quarter the speed of light.]

[When it touches the inner core, it will bounce outwards. ]

[Forming a huge shock wave! ]

[And a large amount of matter and energy is spread into the universe at an extremely alarming speed. ]

【A large number of spectacular nebulae and other new celestial bodies were formed. 】

[This! Is a supernova explosion! ]

[The excessive electromagnetic radiation brought by a supernova explosion can even illuminate the entire galaxy! ]

[It can be called the most shining moment in the entire universe. ]

【Humans on Earth can see it by looking up. 】

【Its daybreak!】

Northern Song Dynasty.

In Sitian Prison.

The officials of the Imperial Observatory were collectively shocked!
　I’m back now, working on the manuscript!
