"I think it's necessary for me to learn more about quantum physics," Ke Xun sighed with his head on his hips, "I never thought that a painting dominated by gods and ghosts would even talk about science. Is this a joke?"
The water on Mu Yiran's body was dry, and he put on his clothes again and pointed to the void on his head: "Particles are the smallest and most basic units that make up matter. All matter is made up of particles. Some physicists believe that microscopic particles are Both have wave-particle duality. Light, for example, has both wave and particle properties."
Ke Xun nodded: "I understand this part."
"I have to mention the double-slit interference experiment of light here. Did you learn it when you were in school?" Mu Yiran asked him.
Ke Xun scratched his head: "You know, I got an amazing score of 13 points in the physics test, and these 13 points were all based on multiple-choice questions... I basically read comics or slept in physics class, and now I think about it, about Physics I can only remember the rosacea on the physics teacher's face..."
Mu Yiran shook his head slightly helplessly, stretched out his hand to squeeze the back of Ke Xun's neck, and then rubbed the dog's head: "Light is composed of photons, and photons are also particles.
"The double slit interference experiment is to put a candle in front of a piece of A paper with a small hole, and behind the A paper is a piece of B paper. On the B paper, there are two parallel and vertical lines. Slot, put another screen behind the B paper as a screen.
"Light enters through a small hole in paper A, passes through two slits in paper B, and hits the screen. What shape do you think the light spot projected on the screen will be?"
Ke Xun laughed: "As soon as you ask this question, I know that the answer is definitely not what I thought, but just answer it as I think - according to the inertial thinking of an ignorant scumbag, there should be two lines on the screen. A long, narrow spot like a slit on paper B."
"Light is composed of many light particles. Indeed, according to the usual thinking, a bunch of light particles drilled through the gap should form two long and narrow beams of light, and then projected onto the screen." Qin Ci interjected.
Mu Yi nodded and continued: "However, what actually appears on the screen is a fence-like pattern of light and dark. This pattern of light is caused by the superposition of different brightness of light. And this different brightness The phenomenon of superposition is also caused by the 'constructive interference' and 'destructive interference' of 'waves', which is the double-slit interference phenomenon of light.
"This phenomenon and experiment just confirms that light has both particle and wave properties - because 'waves' have 'constructive interference' and 'destructive interference' - which is what we call light has 'Wave-Particle Duality'.
"But this experiment is not over yet. In order to further observe this phenomenon, scientists have used scientific equipment to conduct microscopic observations in order to find out how photons interfere through the two slits.
"So an incredible thing happened. When people use scientific equipment to observe, the interference of light disappears, and what appears on the screen becomes two long and narrow light patterns. Those grating stripes that alternate between bright and dark actually do not appear— At this point, the light seems to revert to a single, particle-only property.
"After this, the researchers conducted a third related experiment, this time replacing photons with electrons and emitting only one electron at a time.
"According to common sense, it is impossible for a single electron to interfere, because the so-called interference requires at least two or more numbers to be generated. Then what is projected on the screen should be a single particle state.
"However, the result was still unexpected, a single electron actually interfered.
"It makes people very confused. Who is the single electron interfering with? How can a single electron enter the two gaps at the same time and cause interference?"
When it came to this, Ke Xun and Qin Ci had a blast.
"Fuck..." Ke Xun rubbed his arms, "What's the situation? It's obviously a scientific phenomenon, why does it sound a little... terrifying?"
"The electron is also a particle, and it is already the smallest individual and unit, which means that it can no longer be divided into two parts, it can only be a single part, but how does it pass through two gaps at the same time?" Qin Ci also had suspicion in his eyes.
Mu Yiran looked up at the void above his head: "In order to know the answer to this question, the researchers installed a camera in the originally sealed device to observe how a single electron crosses the double slit at the same time and interferes.
"Next, something incredible happened—the same single-electron double-slit interference experiment was done after installing the camera, and the interference phenomenon disappeared. After taking out the camera and doing it again, the interference phenomenon appeared again.
"Such repeated experiments, no matter who does it and where it is done, all the results are the same, that is: when the camera is installed, the interference phenomenon disappears; when the camera is removed, the interference phenomenon appears.
"In other words, when we're not observing it, it's in a superposition that's both a particle and a wave, and when we're observing it, it's in a particle state. It seems that our observations, affecting the outcome, only We made the act of 'observing', and it collapsed from the state of superposition of waves and particles to the state of particles.
"And here comes the scariest part of quantum mechanics—the particle, as if it's conscious, can see our behavior, and as long as we're looking at it, it can detect it and behave differently because of it.
"Then here comes the question - all matter in the universe is composed of particles, and the state of the particle is determined by the 'consciousness' it has. Then, is everything in this universe composed of matter, or is it determined by matter? Consciousness decision? Is it objectively existing or subjectively constructed
"Whose consciousness is the 'consciousness' of these particles? Whose subjectivity is this universe's subjectivity
"In this world, did matter come first, or did consciousness come first? This consciousness - after all, whose consciousness is it?"
"Fuck-fuck! I'm scared to death!" Ke Xun took a step back, covered his chest with one hand, and looked at Mu Yiran in horror, "Yiran, what you said is really the real world. Scientific conclusions in science fiction?! It's really not made up in some sci-fi movie?!"
Mu Yiran dragged him in front of him - he jumped a step back and stepped on the iron plate, then looked at him calmly: "What I'm talking about is the scientific theory in the real world, but it can't be called for the time being. It is a 'conclusion', after all, there are still too many mysteries in the quantum mechanics community that have not been solved yet, but this theory of consciousness does exist."
"... I'm really scared to death," Ke Xun grabbed Mu Yiran's hand and rubbed his chest vigorously, "After living for more than 20 years, I was suddenly told today that this universe may have been created by the consciousness of an unimaginable living body. - It has subverted the cognition of my small life, I am me, I have been completely reshaped my world view...
"Before I entered the painting, I had always been firm in materialism, but I scoffed whenever I heard about the gods and ghosts. Even if I encountered an event in the painting later, I never thought that its behind-the-scenes power could override the laws of the universe. up, the result—
"As a result, a theory suddenly tells me that there may really be a creator-like existence in this universe?! Could it be that the power behind the painting is of the same magnitude as it?! Then we are still struggling..."
"Ke Xun, calm down." Mu Yiran held Ke Xun's cheeks with both hands and let him look at him, "What kind of existence is the power behind the painting, let's not think about it now, the most important thing right now is , is from these scientific theories that are closely related to this painting, to find the clues of the signature, let us leave this painting first."
"Okay, okay... You wait for me, I'll calm down." Ke Xun turned and took a few deep breaths.
Mu Yiran turned his head to look at Qin Ci, and saw that he seemed a little unacceptable, there was still horror on his face, and the whole person froze in place.
"I know..." Qin Ci swallowed his saliva and said with difficulty, "Why do people say that those who study physics are crazy... Today I only learned a little through you, and I feel like I'm going crazy. People who know more about physics are likely to encounter more confusion and unimaginable things, and probably feel like they are going crazy every day.”
Ke Xun turned around, wiped the sweat on his forehead, which might be hot or frightened, and said, "Let's not care whether those people are crazy or not, just say that in front of us—since all matter in the macroscopic world is made of A large number of microscopic particles are piled up, so macroscopic matter also has a quantum superposition state, right?"
"This involves the battle between the two factions in the quantum physics world that Haowen mentioned before." Mu Yiran said, "If the macroscopic world is like the particles of the microscopic world, there are multiple superpositions of indeterminate states, then It means that the macroscopic world has no laws and is completely determined by random events, because it cannot be determined and cannot be accurately measured, and all possibilities are just a probability, not an exact value. Einstein and Schrödinger disagreed with this view, So the 'Schrödinger's cat' theory was born, which is used to satirize this so-called macroscopic 'quantum superposition' and 'uncertainty' or 'uncertainty' theory."
"So, in this program, is he in favor of the quantum superposition state of the macroscopic world, or is he mocking this theory like Schrödinger?" Qin Ci frowned.
Mu Yiran's eyes were slightly deep, and he spoke slowly, word for word: "In fact, before Cheng Cheng's son's accident, in the world's top scientific and technological academic journal "Nature", a scientific researcher from a certain country said that they The 'Schrödinger's cat' state of many particles has been achieved through technology, that is to say, a quantum superposition state at the macroscopic scale has basically been realized."
Qin Ci and Ke Xun were shocked again, Qin Ci said: "So you mean that the program recognizes the quantum superposition state of the macroscopic world? The title of this painting "Schrödinger's Cat" is not antonymous, but means that the program is Believe that 'Schrödinger's cat' states can exist in the macroscopic world?"
Mu Yiran nodded slightly: "Yes, that's what I think."
"So..." Ke Xun rubbed the hair on the back of his head, "We in the painting he created are likely to be influenced by the consciousness in his painting. At this moment, we may really be a kind of born dead again?"
