Chapter 241 [Light Core]
"Xiao Zhou, have you watched "Superman"?" Gu Cheng said suddenly.
Zhou Huang: "Superman? DC Superman? Of course I've seen it, what's wrong? ”
Gu Cheng: "You've seen it, right?" Then you should know the source of Kryptonians' combat energy, right? ”
Zhou Huang: "Commonly known as basking in the sun." Belch...... Boss, what are you talking about? ”
Gu Cheng crossed Erlang's 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, making it the third-generation energy core of my Tianqing Technology. ”
Zhou Huang's eyes lit up, and he subconsciously said: "Is it a miniaturized controllable nuclear fusion device?" ”
The principle of the energy obtained by the isotope core is, to put it bluntly, to use the energy released by the decay of its substance, and the higher energy source is nuclear energy.
As long as controllable nuclear fusion can be realized, the nuclear energy on the earth will not be used up at the current level of human energy consumption, which is equivalent to unlimited energy, not to mention that there is a lot of helium three on the moon, not to mention the entire solar system.
However, Zhou Huang, who was gradually excited, couldn't help but darken his eyes when he saw Gu Cheng shaking his head and denying it, controllable nuclear fusion is really forever 50 years, even the boss shook his head, if humans want to realize this dream, they really have to wait until the rhythm of the Year of the Monkey.
Gu Cheng suddenly said: "The energy core device I want to build is a container used to capture a large amount of light, and let the light be used by me, so it is called ...... 'Light Quantum Core'?" Or 'photonic core'? Forget it, let's call it 'Light Cores'. Light is the energy that is truly ubiquitous and readily available, and it also has an almost rogue property, all material particles known to mankind have a half-life, but light has no half-life. ”
Light can be divided into many kinds according to different divisions.
In terms of color, Newton divided light into seven colors; According to the generation mechanism, it can be divided into ordinary light and laser; According to whether it is visible to the naked eye or not, it can be divided into visible light and invisible off, according to high-energy physics, guan is a kind of elementary particle, or it can be a kind of wave.
To put it simply, some characteristics of light, or photons: zero electric charge; Wave-particle duality; It is responsible for transmitting electromagnetic force and can move over long distances; The speed of propagation is the speed of light; Zero resting mass......
Photons do not have a static mass but have a moving mass.
According to Einstein's special theory of relativity, energy and mass are equivalent, light is a kind of energy, so Guan also has mass, but the mass here is not the mass of ordinary matter, which also means that the photon is moving at the speed of light relative to anything, it can't stop at all, and stopping means disappearing, that is, being absorbed by other substances.
"Device for capturing light......" Zhou Huang pondered Gu Cheng's words carefully, and after reacting, his eyes suddenly bulged, and he looked at Gu Cheng and exclaimed: "Boss, the static quality of light is strictly zero, if you can create this kind of device that can capture light, if the light energy is captured and packed in a container, it means that it is given a static mass, I can only say that the entire physical system building that has been successfully built now will face collapse!" ”
A question instantly popped up in Zhou Huang's mind: what would happen to the world if light, or photons, had a static mass?
If the rest mass of light is not zero, and Coulomb's law is not strictly inversely proportional to squares, all the classical theories, Maxwell's equations, and the Lagrangian quantities of electromagnetic fields, will collapse.
The physical system of most fields, such as space-time, the speed of light, quantum, etc., will collapse.
It's just ruined......
If light has a static mass, embodied in the world seen by the naked eye, everything related to light will be affected, which means that photons will have a huge mass when accelerating to close to the speed of light, and light will become a "killing weapon", and the original warm sunlight will shine on people...... In Zhou Huang's view, this is simply a disaster.
"It's crazy, boss, Maxwell, Brother Ai's coffin board can't be suppressed!!" ::
Although human beings have begun to use light energy for a long time, they do not directly capture and collect photons, which are the fastest propagating in the known universe, and they have been moving at the speed of light and cannot be stopped.
"Why do you have to stop catching light? Continuing to let the light fly for a while did not violate the existing laws of physics. Gu Cheng smiled calmly, and then moved his wheelchair to the side of the console.
Zhou Huang was still acceptable when he heard this, and immediately came to Gu Cheng's side and saw that he was building a mathematical model.
Gu Cheng said on the side: "Take advantage of a 'singularity' phenomenon. The so-called 'singularity' refers to the merger of two different modes of light waves into one mode of light waves, when this happens, the light will be constrained to the original trajectory, but the light itself will also be lost on these 'singularities', so if you want to prevent it from being lost, you also need a waveguide with 'cosmic-temporal symmetry' to prevent this loss, so that they can accurately balance each other, which means that when the light reaches the 'singularity' merge, the intensity of the light remains the same. ”
Light has wave-particle duality, if you use a phosphor screen to receive light, it is a small ball-like particle, which can make a bright spot on the phosphor screen; If you use an interferometer to observe it, it becomes a wave, and it also has the properties of waves, and if you use a metal plate to observe, it becomes the smallest unit of energy and becomes an energy pon, which is the famous Einstein photoelectric effect experiment, and Aige gave this energy particle a name optical quantum.
"Waveguide..."Zhou Huang pondered for a while, and said curiously: "Optical fiber is also a waveguide, boss, is it possible that this capture device also uses the total reflection principle of the light guide?" ”
"Uh-huh......" Gu Cheng stared at the screen and quickly constructed a mathematical theoretical model.
The well-known optical fiber is the use of the principle of total reflection, the propagation speed of light in different substances is different, the speed in the vacuum is the fastest, that is, the speed of light, when the light passes through the medium, the speed will slow down, the propagation speed of light in the glass is equivalent to two-thirds of the speed of light in the vacuum.
When light travels from one substance to another, the interface between the two substances will be refracted and reflected, 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 disappears and all the incident light is reflected back, that is, total reflection.
However, this only ensures that the light will not be refracted and lost, and it will still run away through the other port of the waveguide, because it is impossible for the light to stop.
Gu Cheng allowed Zhou Huang to casually look at the theoretical mathematical model he was building, and even answered some doubts for him.
Zhou Huang could still understand it at first, including the total reflection of the light guide, but when he saw the mathematical model of the light guide device and then established a closed-loop loop, he couldn't understand it, and the light collected in it would never run out and move in a loop.
After more than ten minutes, Gu Cheng tapped the spacebar on the keyboard for the last time and said, "Xiaoqing, take it and simulate it." ”
Zhou Huang saw that he was idle, and he had countless questions in his heart, 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 smiling: "If you don't make a decision, quantum mechanics." In the quantum electrodynamics QED theory, the electromagnetic interaction is described as the exchange of 'virtual photons', the virtual photons have energy and momentum, and the transfer of energy and momentum is completed in the process of exchange, the quantum fluctuations in the vacuum produce 'virtual particles', and the existence of electric charges will stimulate the formation of 'virtual photons', and because of the uncertainty principle, the existence of 'virtual photons' is extremely short, and the energy of virtual photons is to the vacuum' In the end, it must be instantly annihilated and returned to the universe, otherwise the conservation of energy will be invalid. ”
When he heard Gu Cheng's words, Zhou Huang hugged his head with a painful face, spread his hands and said, "So it's essentially a 'borrowed' vacuum zero point energy?" ”
Zhou Huang felt very painful, he felt that his IQ was gradually unable to keep up, vacuum zero point energy is the most cutting-edge concept in the field of quantum mechanics, if human beings can use vacuum zero point energy, this energy is more than 10,000 times higher than controllable nuclear fusion, it is a real inexhaustible existence.
Gu Cheng shook his head and denied: "No, no, vacuum zero can seem very good, but capturing it is more harsh than capturing light, and this is 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 make more and more trouble for myself." ”
Entropy is a thing that either does not change, or it increases entropy, and it will definitely not decrease entropy.
To give an easy-to-understand example, if a whole glass is placed on the table, if its state at the moment represents the initial entropy value, the entropy increases when the glass falls to the ground and is broken. If the entropy can be reduced after it has increased, it means that the glass can be returned to its original intact state after it is broken, which is equivalent to going back to the past 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 have to worry about its fluctuations, it is best for the well water not to interfere with the river water, I want two or more light waves to reach the 'singularity' and merge into a new type of photon pair to interact, it's as simple as that." ”
When Zhou Huang heard this, he immediately collapsed and said, "Is this still simple? Is it easy to corner with Thomas Young's double-slit interference? ”
Ordinary people know what happens when the beams of two flashlights cross in the dark? Take two flashlights and shine them, and you will find that when the beams cross, they still go their own way.
A more rigorous experiment is the classic double-slit interference experiment.
No wonder quantum field theory was introduced...
