"What happens if the enemy fleet falls into that little black hole?"

AI Vali asked suddenly, with interest, as he didn't have any answers in his database. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"What happens if you fall into a black hole?" Yuan Haochen asked softly, in fact, he had also thought about such thoughts.

"Many people think that when they fall into a black hole, they will probably be crushed and torn to pieces. But the reality may be a little weirder than we thought. Yuan Haochen knew very well that the entire scientific team and the computer team controlled by WALL-E were calculating the data obtained from the experiment just now, so he took advantage of this gap to continue chatting with WALL-E, "The moment the local fleet falls into a black hole, reality may be split in two. ”

"Split in two?" Vali asked, confused.

"In one scenario, the enemy fleet will be instantly reduced to ashes, shredded into elementary particles, and then mercilessly devoured by a black hole, just like the interstellar matter we just saw. And in another scenario, the enemy fleet is almost unscathed. ”

"So, which one is real and which one is illusory?" WALL-E seemed to be intrigued by this part of the knowledge, and continued to ask.

"Both scenarios may be true." The corners of Yuan Haochen's mouth lifted, and a puzzled smile appeared on his face.

"It's all real, how is that possible?" Hearing this, Vali simulated a surprised tone and expression.

"What is a black hole in your database?" Yuan Haochen asked meaningfully?

"What is a black hole? A black hole is an extreme object in space. The gravitational pull of a black hole is so great that the escape velocity within the event horizon is greater than the speed of light. Vali read as he read it.

"Yes, a black hole is a strange celestial body, and inside it, many of the laws of physics that we know no longer work. The gravitational pull of a black hole bends space-time, distorting space-time itself, to the point that a depression-like area is formed in the real space-time around the black hole. ”

"The outermost layer of a black hole is the edge of its event horizon, which is the boundary of the gravitational sphere from which light begins to be unable to escape. In the lower dimensions, outside of this area, light can escape, and once this boundary is crossed, any attempt to escape will be futile. As enemy fleets descend deeper into the black hole, space-time becomes more distorted until it reaches the core of the black hole, where space-time distorts to an infinite degree, known as the "singularity". There space and time no longer make sense, and the laws of physics based on the concepts of time and space as we know them will all fail. ”

Yuan Haochen recalled the scene when he entered the center of the Dutar black hole with the help of scientists from the dark energy civilization to explore singularity data.

"Yes, I understand all of this." WALL-E also studied the results of the year's black hole research.

"The moment you fall into a black hole - you are dead, but at the same time you are alive." Next, a seemingly tricky sentence suddenly came out of Yuan Haochen's mouth.

"Boss, there is a logical contradiction in your statement, I don't understand." Vali said helplessly.

"Back to the previous question, what will happen if the enemy fleet really falls into the small black hole we have created? First, assuming we are still at a safe distance and watching carefully, we will witness a series of bizarre phenomena. Hara continued to describe the image in his mind, "As the enemy fleet continues to accelerate its descent towards the edge of the black hole's horizon. We will see the fleet gradually elongated and distorted, like what it feels like to look through a magnifying glass. And as the enemy fleet gets closer to the edge of the horizon, we find that the fleet seems to move more and more slowly, as if looking at slow-motion footage. ”

"There's probably no way they can send out signals." Vali asked.

"Maybe they can use a strong flash of light to send out a signal. But flashes of light do not necessarily escape the gravitational pull of a black hole. Even if we can see the flashes of light emitted by them, the speed of the signal transmitted outward will become very slow, and the wavelength of the light has been severely stretched in the strong gravitational field, and the frequency has become very low. ”

"If the enemy fleet is cursing us, it should be like this: I~~hate~~you~~!! I... Hate...... You...... Guys~~"

WALL-E simulates an eerie, elongated sound through a voice system.

"Shouldn't they be shouting for help?" Yuan Haochen chuckled, shook his head and continued, "When the local fleet finally reaches the edge of the horizon, we will happen that they suddenly stand still, as if the gods have pressed the pause button. The enemy ship will stay there, motionless, and its stretched body will begin to slowly be devoured......"

"Like what we just observed?" "The enemy fleet will gradually turn to ashes due to the stretching of space, the stillness of time, and the high heat generated by Hawking radiation, and become tiny elementary particles that merge with black holes." ”

"Yes, that's exactly what we're observing." Yuan Haochen's words changed, "However, what the enemy fleet actually experienced will be even more strange. ”

"You're dead, but at the same time you're alive?" Vali imitated Hara's tone and repeated the previous sentence full of logical contradictions.

"It's hard to understand, but in their eyes, nothing really happened."

"That's incredible!"

"As the enemy fleet falls, they don't feel stretching, slowing down, or the terrible radiation." Yuan Haochen continued to analyze.

"Why?" Vali asked, surprised.

"This is because they are in free fall, so they don't feel gravity. After all, the edge of the horizon is not a hard wall, but a kind of spatial invisible boundary. Observers on the outside, like us, are not able to witness what is happening inside this boundary. ”

"In fact, the smaller the black hole you fall into, the bigger the problem. The smaller the black hole, the stronger the gravitational pull will be felt. For example, your legs feel a much stronger gravitational pull than your head, and you may be stretched like a spaghetti. But if you fall into a large black hole, the gravitational difference that tears people apart will become so small that it is almost negligible. Yuan Haochen continued to describe.

"How did you test these inferences, boss, when we entered the interior of the Dutar black hole through high-latitude space, we did not obtain relevant observation data." Vali asked.

"These are the conclusions I have come to through the calculus of the black hole model, and of course, there are some conjecture factors." Yuan continued, "Theoretically, in a black hole that is large enough, people who fall into it can even spend the rest of their lives normally, until they finally fall to the singularity in the center of the black hole, and then they will die. ”

"Spend the rest of your life normally!?" Again he asked, puzzled, "Isn't it a rift that falls into the space-time continuum?" This process should be completely independent of our will. ”

"Indeed, the river of time flows forward eternally, and we can only move forward with time, and there is no way to turn back." Yuan Haochen said quietly.

"Boss, you're so profound." WALL-E's phantom shook his head repeatedly, "You know, the biggest fear of an AI is when it encounters a philosophical problem. ”

"Space and time are distorted to an extreme extent by black holes, in the sense that it is time that pushes you to the final singularity. You can't go back and escape the black hole, just as we can't go back and go back to the past of the current plane. Yuan Haochen was silent for a while and asked, "Do you understand now?" ”

"I don't understand ......" Vali's phantom shook his head, but he looked sluggish.

PS: The second one is a little harder, and I will probably finish it in the middle of the night. If it's too late, everyone will rest early and see again tomorrow, thank you for your support.
