Chapter 353 The strongest substance in the universe!
As the official astronomical institution of the court.
The Sitianjian itself was responsible for studying the sky.
And during this period of time when the sky appears.
The Sitianjian not only expanded its staff greatly, but also studied and recorded the celestial bodies.
And whenever Tianmu talked about knowledge related to the universe and astronomy, the Sitianjian would collectively stop everything else they were doing.
Specialize in studying the cosmic astronomical knowledge of the sky.
And this time, I watched the sky tell the story of the moment when a star died, and the final brilliant fireworks.
Supernova explosion.
Almost all the members of the Sitianjian thought of the "Guest Star at the Gate of Heaven" in the first year of Zhihe during the reign of Emperor Renzong!
At that time, the guest star shone continuously for more than 20 days.
Clearly visible during the day.
It is also brighter than the moon at night.
Although it gradually dimmed later, it lasted for several years before disappearing.
Naturally, that astronomical wonder attracted long-term research from the entire Astronomical Observatory.
The historical records also recorded: "In the first year of Zhihe, on the fifth month, a guest star appeared on the side of the Tianguan Pass. It was visible during the day like Taibai, with four sharp horns, red in color and slow in movement. On the sixth month, on the 23rd day, the guest star was visible."
The members of the Imperial Observatory realized it almost instantly.
"Ah? It turns out that the Tianguan guest star exploded as a supernova!"
"A star explosion, equivalent to the dazzling light produced by the explosion of the sun?"
"So that's it? That's it!"
Everyone in the Imperial Observatory of the Northern Song Dynasty was delighted.
And the sky continues.
[After the supernova explosion, a neutron star is formed.]
[There is also a situation where, for example, when a binary star system merges, there is a chance that a neutron star will be produced.]
[When two stars of similar mass rotate towards each other, they will form a gravitational interaction, eventually causing a collision and fusion.]
【During this period, if a certain critical point is reached. 】
[The core of the star will also collapse violently, forming a neutron star.]
[No matter which situation the neutron star is formed in. ]
[Ultimately, the mass of a neutron star will reach the level of the sun or even higher, while the radius is usually only a few thousand meters or a dozen kilometers.]
The sky screen describes the birth process of a neutron star.
Some images of supernova explosions are also given.
Although it was synthesized through computer technology.
But it's still very shocking!
The ancients clearly saw that moment of shining in the deep night sky of the universe.
It seemed to illuminate the entire universe.
And in the process of shining.
Everything in the cosmic background is covered by a short period of strong light.
The energy contained in this super-large-scale explosion.
Even those who know nothing about cosmic astronomy.
It can also be clearly felt.
Spring and Autumn.
Confucius was originally giving a lecture to his disciples.
What he was talking about was the debate he had with two children about the sun.
And later, after seeing Tianmu's description of the sun.
New understandings generated by oneself.
And now, a new celestial body, the neutron star, has been seen.
Confucius was also full of interests.
Confucius said to his disciples:
"If our thoughts and inspirations have a source."
“Then the biggest source of inspiration must be the universe.”
"Every time I watch these videos about the universe, I can deeply feel the vastness of the heavens and the earth, and the boundlessness of the universe."
"It's as if the whole person's thoughts have traveled beyond billions of spaces."
"I don't know if you have ever had this kind of situation."
Obviously, Confucius is a strong and powerful man.
He is very fascinated by the sky related to cosmic astronomy.
Although the disciples may not necessarily have the same feelings as Confucius.
But seeing that their teacher was so engrossed, they naturally would not spoil the fun.
So they nodded and said: Me too.
And Tianmu continued to talk about how terrifying neutron stars are.
[When a neutron star is just formed, the temperature can reach over 1500 billion degrees! ]
[Even for a neutron star in its stable phase, the surface temperature exceeds 100 million degrees.]
[In comparison, the surface temperature of the sun is only 6000 degrees.]
[The diameter of a neutron star is only about 10 kilometers, but its mass exceeds that of the sun. ]
[This also makes the gravity of neutron stars extremely extreme. ]
[The mass of a neutron star as big as a glass of water exceeds the mass of Mount Everest.]
[Moreover, the density of neutron stars is also extremely high, and their gravity is extremely strong, second only to black holes in the entire universe.]
[Its strong gravitational force can even distort the surrounding light. ]
[If humans want to leave a neutron star, they must reach a speed of more than 15 kilometers per second, which is half the speed of light.]
【Only then can it possibly break free from the strong gravitational pull of a neutron star.】
[At the same time, neutron stars are also the fastest rotating celestial bodies in the universe. ]
[Its rotation speed can reach more than 1000 revolutions per second]
【And if a human being is attracted by the gravity of a neutron star and hits it. 】
[The energy generated is equivalent to the energy of 14000 Little Boys exploding.]
[But such a violent impact has no effect on the surface of the neutron star. ]
[Because the surface of the neutron star has a solid outer shell. ]
[This outer shell is mainly composed of iron elements left over from the supernova explosion, and they are squeezed together.]
[Under strong pressure, protons and neutrons will rearrange to form nuclear planes.]
[The nuclear surface is the strongest substance in the universe and can hardly be destroyed by any means. ]
[As I just said, the power of more than 14000 atomic bombs exploding at the same time.]
[Not even a trace can be left on the surface of the core. ]
[However, it is actually impossible for humans to ever reach a neutron star. ]
[When a living person approaches a neutron star, he or she will be completely decomposed by the neutron star's powerful magnetic field.]
【And not from the outside, but from the inside! 】
[This is because under the gravitational force of the magnetic field, the blood inside the human body will form an extremely strong impact force, just like a bullet shot from the inside out.]
【Completely decompose people.】
[This is why neutron stars are among the most terrifying objects in the universe.]
[But in fact, our lives are also closely related to neutron stars. ]
[Most of the heavy elements in the universe are thought to be produced as a result of neutron star collisions.]
[When two neutron stars collide with each other, a large amount of heavy elements will be synthesized and released, and spread in the universe. ]
[This includes gold! 】
【As for gold, its specialness to us humans needs no further explanation. 】
[So even though neutron stars are scary, we humans don’t need to be afraid of them. ]
[After all, if neutron stars really pose a threat to humans, we humans basically have no means to counter it. ]
The sky screen video ends here.
In the first half of the film, the horror of neutron stars is mainly described.
But in the second half, neutron stars and gold are described in a relatively romantic way.
This has eliminated the fears of many modern audiences, or ancient people.
This also makes people feel very happy after watching this sky-high video.
And actively and enthusiastically discuss it.
"If Heaven had not created me as a neutron star, the universe would have been in darkness forever!"
"Neutron stars don't carry electrons, so they don't conduct electricity?"
Neutron Star: "No Chemistry Here."
What would life be like on neutron stars?
"There is a novel that seems to be about neutron stars."
"Which is more powerful: neutron stars, quasars, or black holes?"
"If we put a coil near a neutron star, wouldn't it be able to generate a lot of electricity continuously?"
"I don't believe that a water droplet can hit a neutron star. The neutron star can block it!"
The ancients had no say in the discussion about neutron stars, but they watched the discussion on the forum with great interest.
And a new sky curtain also appeared immediately.
And the opening was so explosive that it shocked the listeners!
