Chapter 242 [Light Quantity Core]

"Xiao Zhou, have you seen "Superman"?" Gu Cheng said suddenly.

Zhou Huang: "Superman? DC Superman? Of course I've seen it. What's wrong?"

Gu Cheng: "Have you seen it? Then you should know the source of Kryptonians' fighting energy?"

Zhou Huang: "Commonly known as basking in the sun. Uh...boss, what are you talking about?"

Gu Cheng crossed his legs in front of the computer screen, leaned back against the chair and looked around, and said slowly: "Recently, I have been thinking about building an energy core that is more powerful than the isotope core to meet the needs of technological progress, so that it can become my Tianqing core. The third-generation energy core of technology."

Zhou Huang's eyes lit up, and he subconsciously asked, "Could it be a miniaturized controllable nuclear fusion device?"

The principle of obtaining energy from the isotope core is, to put it bluntly, to use the energy released by the decay of its substances. A higher level of energy than this is nuclear energy.

And controllable nuclear fusion can be said to be an infinite energy source that human beings have been thinking about for a long time. As long as controllable nuclear fusion can be realized, the nuclear energy on the earth will not be needed until the sun explodes billions of years from now at the current energy consumption level of human beings. After that, it is equivalent to infinite energy, not to mention that there is still a lot of helium-[-] on the moon, let alone the entire solar system.

However, when Zhou Huang, who was gradually excited, saw Gu Cheng shaking his head and denying it, his eyes darkened. Controlled nuclear fusion is indeed 50 years forever. Even the boss shook his head. Humans really have to wait until the year of the monkey to realize this dream. .

Gu Cheng suddenly said: "The energy core device I want to build is a container for capturing a large amount of light and using it for my own use. It's called...'Optical Quantum Core'? Or 'Photon Core'? Forget it Let’s call it the ‘light quantity core’. Light is the energy that is truly ubiquitous and readily available, and it also has a property that is almost rogue. All known matter particles have a half-life, but light has no half-life.”

Light can be divided into many kinds according to different methods.

According to color, Newton divided light into seven colors; according to the mechanism of production, it can be divided into ordinary light and laser; according to whether it can be seen by the naked eye, it can be divided into visible light and invisible light. kind of wave.

To put it simply, some characteristics of light or photons: the charge is zero; it has wave-particle duality; it is responsible for transmitting electromagnetic force and can move long distances; the propagation speed is the speed of light; the rest mass is zero...

A photon has no rest mass, but a dynamic mass.

According to Einstein's special theory of relativity, energy and mass are equivalent, light is a kind of energy, so it also has mass, but the mass here is not the mass of ordinary matter, which also means that photons move at the speed of light relative to everything, It can't stop at all, and stopping means disappearing, that is, being absorbed by other substances.

"A device that captures light..." Zhou Huang pondered Gu Cheng's words carefully, and when he realized it, his eyes bulged, and he couldn't help exclaiming while looking at Gu Cheng: "Boss, the rest quality of light is strictly zero. If you Can create this kind of device that can capture light, if light can be captured and placed in a container, it means giving it a rest mass, I can only say that the entire physical system building that has been successfully constructed now will face collapse!"

A question suddenly popped up in Zhou Huang's mind: what would happen in this world if light or photons had a rest mass?
First of all, quantum electrodynamics will lose gauge invariance, which makes this theory impossible to renormalize. If the rest mass of light is not zero, Coulomb's law is not a strict inverse square law. All related classical theories, Maxwell's equations and electromagnetic fields The Lagrangian of will collapse.

The physical systems in most fields such as space-time, light speed, and quantum will collapse.

It just ruins the three views...

If light has a rest quality, reflected in the world seen by the naked eye, all things related to light will be affected, which means that photons will have a huge mass when they are accelerated to close to the speed of light, and light will become a "killing weapon". The sun shines on people... In Zhou Huang's view, this is simply a disaster.

"It's crazy, Boss, Maxwell, Brother Ai, and their coffin boards can't be held down anymore!!!"

Although human beings have already started to use light energy early, they did not directly capture and collect photons. Photons are the fastest propagation speed in the known universe, and they have been moving at the speed of light and cannot stop.

"Why do you have to stop the light to capture the light? Keep letting the light fly for a while, and it doesn't violate the existing laws of physics." Gu Cheng smiled calmly, and immediately moved the wheelchair to the side of the console.

When Zhou Huang heard this, he could still accept it, and immediately came to Gu Cheng's side, and saw that he was building a mathematical model.

Gu Cheng said at the same time: "Using a phenomenon of 'singularity'. The so-called 'singularity' means that two different modes of light waves merge into one mode of light waves. When this happens, the light will be confined in the original Some trajectories, but the light itself will be lost on these 'singular points', so if you want to prevent it from being lost, you need a waveguide with 'parity-time symmetry' to prevent this loss, so that you can accurately , which means that when the light reaches the 'singularity' and merges, the intensity of the light remains constant."

Light has wave-particle duality. If light is received by a fluorescent screen, it will be a particle like a small ball, which can make a bright spot on the fluorescent screen; and if it is observed by an interferometer, it will become a wave. It has the properties of a wave, and if it is observed with a metal plate, it becomes the smallest unit of energy and becomes an energy quantum. Name - photon.

"Waveguide..." Zhou Huang pondered for a while, and said curiously: "An optical fiber is also a kind of waveguide. Boss, is it possible that this capture device also uses the principle of total reflection of the lightguide?"

"Hmm..." Gu Cheng stared at the screen and quickly constructed a mathematical theoretical model.

The well-known optical fiber uses the principle of total reflection. The propagation speed of light in different substances is different. The speed in vacuum is the fastest, that is, the speed of light. When light passes through the medium, the speed will slow down. The speed of propagation is equivalent to two-thirds of the speed of light in a vacuum.

When light travels from one substance to another, the interface between the two substances will refract and reflect, and the angle of the reflected light will change with the angle of the incident light.

When the angle of the incident light exceeds a certain angle, the refracted light will disappear, and all the incident light will be reflected back, that is, total reflection.

But this can only ensure that the light will not be refracted and lost, it will still run away through the other port of the waveguide, because it is impossible for light to stop.

Gu Cheng allowed Zhou Huang to casually look at the theoretical mathematical model he was constructing, and even answered some doubts for him.

Zhou Huang could understand it at first, including the total reflection of the light guide, but when he saw the mathematical model of the light guide and then built a closed loop, he couldn't understand it. The collected light would never come out, and it was inside circular movement.

After more than ten minutes, Gu Cheng pressed the space bar on the keyboard for the last time and said: "Xiaoqing, use it to simulate."

Seeing that he was idle, Zhou Huang had countless questions in his mind, so he picked one of them and asked, "Boss, how can we use this thing alone?"

Gu Cheng twisted the wheelchair and turned it at an angle, facing Xiao Zhou and said with a smile: "Indeed, quantum mechanics. Here we have to introduce quantum field theory. In the QED theory of quantum electrodynamics, electromagnetic interactions are described as 'virtual photons'." In exchange, virtual photons have energy and momentum, and the transfer of energy and momentum is completed during the exchange process. Quantum fluctuations in the vacuum produce "virtual particles", and the existence of charges will stimulate the formation of "virtual photons", and because According to the uncertainty principle, the "virtual photon" exists for a very short time, and the energy of the virtual photon is "borrowed" from the vacuum, and eventually it must be instantly annihilated and returned to the universe, otherwise the energy conservation will fail."

When he heard Gu Cheng's words, Zhou Huang hugged his head in pain, spread his hands and said, "So it's essentially 'borrowed' vacuum zero-point energy?"

Zhou Huang felt very painful. He felt that his IQ was gradually failing to keep up. Vacuum zero-point energy is the most cutting-edge concept in the field of quantum mechanics. If humans can use vacuum zero-point energy, this energy is simply superior to controllable nuclear fusion. More than ten thousand times, it is a truly inexhaustible existence.

Gu Cheng shook his head and denied: "No, no, vacuum zero-point energy seems to be very good, but capturing it is more demanding than capturing light, and it's not fun. The law of entropy increase in thermodynamics will collapse here, and the causal relationship will be completely messed up. I don’t want to create more and more trouble for myself.”

Entropy is something that either stays the same, or increases entropy, and never decreases entropy.

To give an easy-to-understand example, if a complete glass is placed on the table, if its state at the moment represents the initial entropy value, when the glass falls to the ground and is broken, the entropy increases.If the entropy can be reduced after it increases, it means that the glass can return to its original intact state after being broken, which is equivalent to going back in time and turning back time.

If this is true, chaos will come, and a series of problems will follow.

Gu Cheng added: "In short, we don't care about its fluctuations. It is best not to interfere with the river water. What I want is to let two or more light waves reach the 'singular point' and merge into a new type of photon pair to interact. So simple."

When Zhou Huang heard this sentence, he suddenly collapsed and said, "Is this easy? Is it easy to see Thomas Young's double-slit interference at the corner?"

Ordinary people know what happens when the beams of two flashlights cross in the dark?Take two flashlights and you will find that when the beams cross, they still go their own way.

The more rigorous experiment is the classic double-slit interference experiment.

Xiao Zhou suddenly realized, no wonder the introduction of quantum field theory...

……

　According to the development trend of science and technology, controllable nuclear fusion is a major trend, and many scientific and technological articles have been written, including antimatter.It is not impossible to write about these concepts, but most of the big readers are not interested in anything new, so Zhao Ling thought about finding some other ideas.So there is the story of capturing photons in this chapter. I have to complain about it. Writing "the core of light quantity" is really killing me as a liberal arts student. I am not good at writing about the brain hole of capturing light. In the past two days, I checked more than N materials in order to write a [-]-word chapter.

　　As for the source of inspiration, yes, it is the idea that "Kryptonians" are awesome when they bask in the sun, but I have to give a scientific explanation or something. After all, it is written in a scientific and technological article, so the photon's rest mass is zero. Unavoidable factors, quantum effects, entropy increase law, etc.

　　Zhaoling’s scientific explanation is to hope that the plot of the novel is as logical as possible, but I also hope that the readers of the reasonable party will be light-hearted. After all, liberal arts students can’t afford to hurt ducks~~ New week, can I ask for a ticket...
