The picture on the projection cloth is of two huge white dwarf stars, one foot apart!
But don’t underestimate a foot on the canvas. Maybe in the real universe, this is a distance of several light years!
Lin Haochuan pressed the play button and started playing the picture!
On the projection cloth, two huge white dwarf stars began to slowly move towards each other!
After a while, the two white dwarfs got closer and closer, and due to the mutual gravity, they began to change their orbits!
Subsequently, the trajectories of their two planets began to become distorted!
Just like Tai Chi, one yin and one yang are circling each other!
I don’t know how many times they circled each other!
A huge vortex cyclone has been generated around them!
Even the small planets around them were attracted by this huge gravitational force and collided together!
Finally, the two white dwarfs collided together!
Then it exploded with a 'coaxing' sound.
Of course, this is the sound effect simulated by Lin Haochuan.
If the real sound effects of their collision were played, everyone present would be so shocked that they would bleed to death!
Finally, after the two white dwarfs collided, a dazzling white light was produced!
That was also released by Lin Haochuan in a weakened way. Otherwise, this light would be enough to blind the eyes of all people on earth!
Yes, and inside that white light, the two white dwarfs are getting smaller and smaller, and the light around them is getting brighter and brighter!
Finally, that dazzling white light disappeared with a ‘swish’!
That's right, it disappeared with a 'swish', and then a tiny black dot appeared on the screen.
And, it began to devour endlessly!
This picture was collected by Lin Haochuan using a time traveler to go to the universe on world line B hundreds of millions of years ago, and after hundreds of millions of times of time passed!
Fortunately, Lin Haochuan lives on world A and does not belong to world B.
Otherwise, that white dwarf collision would be enough to wipe out Lin Haochuan!
The screen ends here.
All the students’ eyes widened and their mouths opened wide, speechless!
Lin Haochuan pointed at the black dot on the projection cloth with a white stick and said, "Can anyone tell me what this is?"
Just listen to Li Zixing whisper: "Is it a black hole?"
Because Li Zixing has seen the true appearance of a black hole, she feels that this thing looks very familiar to a black hole!
Lin Haochuan nodded slightly and said: "Classmate Li Zixing answered correctly, yes, this is the so-called black hole in the universe!"
After a pause, Lin Haochuan continued: "Okay, so we already know the formation of the black hole, but can anyone tell me where the two white dwarfs that collided before went?"
"I know, I was swallowed by a black hole!"
Liu Xuebi raised her hand to answer, while Lin Haochuan shook his head!
"I know that all the energy between them must have been converted into the energy of the black hole, and then disappeared!"
After Liu Chicheng finished speaking, Lin Haochuan continued to shake his head and said: "That's not right! Classmate Wang Zhixin, please tell me your understanding!"
Lin Haochuan knew that here, only Wang Zhixin's physics knowledge was a little richer than theirs!
Wang Zhixin coughed and said: "Well, Teacher Lin, I think so! According to the law of conservation of the universe, this black hole is condensed from the energy generated by the collision of two white dwarfs. As for the two white dwarfs,
Where did it go? This, according to my guess, should have neutralized the energy, turned into dust, and scattered in the universe. It’s just that because the screen is zoomed, we can’t see it! Okay, teacher, let me say
It’s over!”
After Wang Zhixin finished speaking, he wiped the sweat from his forehead and sat down in fear!
Yes, this was the first time he felt so nervous in physics!
After all, the person in front of him is Lin Haochuan, and Wang Zhixin cannot guarantee that his theory is correct!
As expected, Lin Haochuan shook his head slightly, then slightly raised the corner of his mouth and said: "Congratulations, not one of you got the answer right, not even one of you touched the edge!"
Lin Haochuan smiled and shook his head helplessly!
But actually, we can’t blame them.
Because without in-depth research and understanding, it is impossible to guess where the two white dwarfs went, and how the tiny black hole was formed!
Lin Haochuan said: "Don't look at this small black hole. Yes, its volume is indeed only about half of the earth, but because it is a newborn black hole, it has not yet begun its long devouring process! And its
The mass is more than billions of times that of the earth, and most of it is composed of the element gallium!"
"Okay, then next, I'm going to tell you how this black hole came out and where the two previous super white dwarfs went! Here comes the important point, take notes!"
"Swipe, swipe, swipe..."
All students, immediately sit up straight and start listening carefully!
Just listen to Lin Haochuan solemnly say: "The huge impact of the two white dwarf stars cannot be withstood by the three-dimensional space, so it breaks the dimension of space! It breaks another world line, commonly known as the parallel world! And I call that parallel world
It’s world line B! Our world is called world line A!”
"Yes, World Line A was originally like a complete wire, with current flowing continuously! Now it's better, because two white dwarfs collided, and a certain part of the wire could not withstand such a large force, so it exploded
It exploded all of a sudden
, all the remaining energy was sent to the B world! As for the B world line, in order to repay the 'good gift' we gave them, they also gave us a 'good gift', that is,
There’s a black hole on this projection cloth!”
"What? Black holes actually come from like this?"
"Nani? What are you talking about? Why can't I understand?"
Lin Haochuan's explanation, comparing the universe to feeding wires, is vivid and vivid!
However, most of the students under the podium still didn’t understand!
And like Li Zixing, she has been to the B world line with Lin Haochuan, so she naturally understands it.
And Wang Zhixin used his many years of knowledge in exploring the universe, so he also understood it!
There are also some people with high understanding ability who understand it all!
I saw Yang Bai's little mushroom head, took off his glasses, and started to press his nose!
Lin Haochuan smiled.
If others don't take notes, Lin Haochuan will definitely scold him to death, but for Yang Bai, it doesn't matter! (To be continued)
