Infinite freedom means that there is no **, God does not have **, and will not rob stupid human beings of things that they think are very precious. This judgment that most shocked Charlotte's heart, she said: "I think you are like a philosopher, really." ”

Unexpectedly, the six-eared macaque said: "Philosophers are used to curse people, because they always say something absolutely true, some of which cannot be verified at all, and some of which are not falsifiable at all, and absolute correctness is useless at all, and saying it is equivalent to not saying it." For example, there are two sides to everything. This is an arbitrary conjecture.

Why does it have to be two-sided? Why not three sides? Our world is three-dimensional, you can't use two to better locate the location of a three-dimensional world, right? In addition to the three-dimensional space, the occurrence of an event also has the time of occurrence, that is, four degrees of freedom, how to describe an event with a dichotomy?

The protagonist of the event is another degree of freedom, what if it is a double protagonist? What if it's multiple protagonists? What if the protagonist is pierced by a soul? What about the transformation of the main character? What about the protagonist's acute transient psychosis? The degrees of freedom are infinite, the real world is linear, and even if there is a steep inflection point, you will see linear details when you zoom in. There are unlimited viewing angles. That's where the world comes in.

In fact, a large part of philosophy has evolved into physicists, and physicists are often confused by their own settings. For example, there is a flaw in the setting of latitude and longitude - people standing on the north and south poles will be dumbfounded, which longitude am I in? It seems that the pole is a very special place. But if the earth is divided into grids, like tennis rackets, the north and south poles have no special characteristics.

Physicists debate whether there is a wall of fire in the vicinity of a black hole, arguing that the sphere from which photons cannot escape is a wall of fire, and that matter that touches the wall of fire is torn apart into elementary particles. Other physicists believe that there is no wall of fire at all, and the reason for this misunderstanding is that we are misled by the angle of observation. Matter close to the black hole will indeed be crushed, but not in the event horizon, but in a continuous process.

For example, in the recently discovered black hole merger event that occurred 1.5 billion years ago, the energy lost through gravitational waves, equivalent to three times the mass of our sun, was converted into energy, and the instantaneous energy exceeded the energy produced by the glow of the stars in the entire universe. ”

Charlotte raised her hand: "I have a question, why is the energy generated by this astronomical event so exaggerated?" ”

Six-Ear-kun: "That's a good question. The motion of the binary black holes is to rotate around each other, much like the largest energy event we have man-made - the large ring particle accelerator. However, the power generated by the particle accelerator is an electromagnetic field, and the power of the binary black holes to rotate is their own gravitational pull.

Gravity, at the level of a black hole, is the most terrifying. We know that the gravitational force is negatively correlated with the square of the distance between objects, and that black holes themselves are already very small by their own gravity, and their extremely small size gives them more opportunities to extend the time of high-speed rotation.

The energy of the black hole merger event is generated by the loss of angular momentum of the black hole, and one of the major differences between the ring particle accelerator and the linear accelerator is that a large amount of energy will be lost in the form of angular momentum.

If you think about Newtonian mechanics, there's one thing that still works well here – gravitational waves exert a force on a black hole, and in turn, the black hole produces a reaction force that stirs the gravitational field strongly. ”

Charlotte, a strange girl, really has the ability to think about physics, she said: "It's really amazing to think about it, there is actually a conversion between matter and energy, this is incredible, have you ever thought about this question, what is the reason behind this?" ”

At this moment, Liuerjun almost forgot that there was a cute girl paper in front of him, and he said: "Of course I have thought about it, and all people who have ambitions in physics have probably thought about it, but there is no particularly good explanation, so I can only think about it." One of the things I guess most often...... Hehe, it's kind of thunderous to say it.

I often wonder what happens when a photon is not a photon. I think that when a photon is transformed into matter, it is still a photon, but it is a sealed photon. There's only one thing that can seal a photon -- and that's a black hole. Therefore, I often wonder if this universe is full of endless black holes, but they are very small, and they are subject to quantum effects, and the sealed photons have a probability of escaping the bondage and often break away from the micro-black holes, so we can't feel the black holes around us.

According to my fallacious theory, all fermions are black holes, protons, neutrons, and electrons. ”

Charlotte was stunned: "Big ...... Uncle, it's really thunderous! ”

Six-Eared: "Really? I know Thunderman, too, but ...... Think about it, why are black holes so strong? It is because it has a large mass in a very small volume, and the effect between the large mass and the ultra-short distance is formed, the distance! This is critical. In the tiny world of fermions, when a photon breaks into the vicinity of a fermion, the distance is so small that a black hole-like event horizon can occur, isn't that reasonable?

When we were still young in science, people often wondered whether the laws of physics on the ground could be applied to distant starry skies, and in the same way, why couldn't the laws of large celestial bodies like black holes be applied to quantum-sized objects? At the quantum scale, the gravitational force is still the shorter the distance, the stronger, why can't there be a quantum-scale horizon that can capture photons? ”

Charlotte thought about it for a long time, felt that this brain hole was strange, and said seriously: "I think you should publish a paper." ”

Liuerjun: "Don't mind, I'm a civil science, just want to be quick for a while, a serious physicist will use a perfect formula to make everyone silent, I can't do it, I haven't learned high math well." I'm blind when people ask me to prove the Pythagorean theorem, so don't be ashamed. ”

Charlotte laughed and said, "You are very self-aware, so you should study math hard." ”

Liuerjun: "Forget it, I'm old, and my brain hurts when I think of mathematics." ”

Charlotte: "That's just your son's success, hey, are you married?" ”

Six-Eared Jun: "...... Can you handle it? ”

Charlotte snorted: "I don't care!" Just ask, stingy! ”

At the end of the brainstorming, Charlotte said enthusiastically: "Today is really a great insight!" I'll keep in touch with you in the future, and I'm still curious about everything. ”

Liuerjun: "I used to talk nonsense with my buddies, but since I started the podcast, I recently had the opportunity to talk nonsense with my sisters, which is really happy." I really thought of asking a question on Zhihu: What is it like to talk about science with a girl? ”

Charlotte: "Huh? Are there any other girls who are also interested in physics? That's really a fellow trader. ”

Looking at her eyes, the six-eared macaque knew that he should retreat, he was an honest man, although he didn't see any evidence of aid, he could be regarded as a full return, he smiled and said goodbye.
