Lin En's explanation was very concise, but the wizards present were skeptical.
Because the experiment in front of him could only be described as weird, and all the changes happened after Lin En expanded his domain!
Even Raphael and others who trusted the magic star couldn't help but wonder if the other party had secretly tampered with the experiment and changed the results. Although no one said this idea, Lin En could see it from everyone's expressions and said it generously again.
"I am the only one who can control the magic network, but it doesn't matter who casts the domain!"
The moment he finished speaking, Lin En withdrew his own territory. He knew that if he didn't let these people try it one by one, no one would be willing to believe that such a counterintuitive phenomenon would really exist.
At the moment the field disappeared, the wizards in the exhibition hall also broke free from their strong perception of the electromagnetic field.
However, no one was in a hurry to use their domain, but everyone looked towards the experimental field at the same time.
The fluorescent screen changed again. The two stripes formed by the light spots gradually dissipated, and nine interference stripes like zebra crossings appeared instead.
"That mysterious interference has started again?!" Sanchez felt as if ghosts were rushing to his body and he was in terrible condition.
The particles are being transmitted along a wave path... This weird feeling that goes completely beyond common sense is really mind-boggling.
"Let me try it." Harof's face was extremely solemn. He was the first to activate the field, and then Lin En connected the perceptions of everyone in the magic network together.
The trajectory of the electrons became regular again...
It passed through the gap obediently and landed on the photosensitive screen at the rear, just like a particle that was accelerated by normal force.
But this normality became abnormal in the eyes of everyone! Harov's domain stopped after one minute, and he fell into deep thought. Then Vittorio and Aurora also tried it.
"It's my turn this time..." "I don't believe it!" "Let me try it too!"
The great wizards present at the meeting also personally experimented after the speakers, but it was as if the electrons were playing a weird game of hide-and-seek with them, and the photosensitive screen kept changing.
"Could it be the influence of the domain?" Arad couldn't help but speak out.
He suspected that there might be something in the void that could affect the movement trajectory of particles, and this force disappeared after they expanded their domain.
"No, it's not a problem with the field. In fact, before conducting this experiment, I tried it with other instruments, such as installing electronic detection equipment behind the two gaps, and the results did not change anything!" Lynn directly rejected Arad's guess.
The reason for choosing to expand the field is simply to allow the wizards present to "see" more clearly.
"So what exactly affects the trajectory of electrons?" Aurora asked.
"If I'm not mistaken, it's probably... observation!" Lin En responded solemnly.
Observation?
Lin En's answer was beyond the expectations of everyone present. Raphael almost pulled his beard off when he heard this. It took him a while to confirm in disbelief.
"You mean to say that because we were observing the electrons, they behaved as particles, and if we stopped observing them, they would suddenly become waves?"
"No, to be precise, without observation, it has both wave and particle characteristics..." Lynn corrected Raphael's words. "I call it the quantum wave-particle duality!"
"It's really ridiculous. How can something be both a particle and a wave?" A great wizard interrupted angrily. This was clearly an insult to his intelligence.
The wizards in the exhibition hall also found it difficult to understand this so-called wave-particle duality. They simply could not imagine such an existence with their brains.
"This kind of wave is not the mechanical wave you understand. I call it probability wave!" Lin En explained.
The so-called probability wave refers to the probability that a microscopic element may appear at a certain point in space at a certain moment. For example, when an electron passes through the slit, it may fall at any position on the photosensitive screen, but the probability of falling in the interference fringe area is relatively higher.
However, this is without observation. Once the field is expanded and the position of the electron at this moment is confirmed, the electron will then move along the determined trajectory and land on the only fixed point.
"That's really..." Sanchez's face twitched constantly as Lin En explained. He couldn't find the right adjective for a long time, and finally could only squeeze out a few words from his teeth. "It's incredible!"
The probability wave that Lin En proposed is even more bizarre than the wave-particle duality! It's like telling you that there is an animal whose form can switch back and forth between many species such as fish, horse, donkey, eagle, etc., and has all their characteristics. It can fly when it needs to go up to the sky, and swim when it needs to go to the sea...
But as soon as you look at it, the shape of this thing will be frozen. Those that can run will not fly, and those that can fly will drown if they fall into the water.
This is even more bizarre than any story. No, it can only be described as outrageous! "Excuse me, Speaker Lin, but I cannot agree with your probability theory... The laws governing the operation of this world must have clear rules, but we just haven't found them." Jeffrey stood up excitedly. His tone, which was originally a little suppressed, soon became louder and louder, and he almost roared in the end.
"There is no such thing as probability in this world!"
From the movement of small objects to the operation of large celestial bodies, everything follows specific laws without exception!
This is almost the most basic logic of magic!
After all, the source of wizards' power is to observe, summarize, and replicate this law, and reproduce it with magical mimicry! For example, in the past, when they used magic to attack the enemy, as long as they confirmed the enemy's distance, direction, and speed, they could calculate the trajectory of the attack with excellent computing power, thus hitting the target 100%.
Now according to Lin En, the microscopic particles that make up the bottom layer of the world actually rely on probability to determine their positions. Without observation, whether the enemy is alive and where they can hit is completely unknown! Jeffrey simply couldn't accept this weird argument! The wizards present had similar ideas. This was not just a simple matter of undermining the foundation of magic, it was simply a blasphemy against magic! "No, you're wrong. Of course there are things in this world that rely on probability, and there are a lot of them..." Lin En took out a gold coin from his arms and threw it up.
"For example, if we throw a gold coin into the air without any manipulation or magical interference, there is a nearly 50% chance that the front or back side will face up."
"But no matter what, before it completely falls and is observed by us, anything can happen!"
The thrown gold coin kept spinning in the air, attracting the attention of all the wizards. At the moment of falling, Lin En suddenly put his palms together to wrap the falling gold coin in the center, blocking everyone's sight.
"Can you guess which side of this gold coin is facing up now?" Lynn asked with a smile.
Is it heads or tails? No, it could be both...
"Of course it's the front side!" Jeffrey said with great confidence, interrupting everyone's thinking. Although the two sides were separated by hundreds of meters just now, with his excellent eyesight, he could clearly see the final falling trajectory of the gold coin.
"Are you sure?" Lin En asked again. "How sure are you?"
Jeffrey opened his mouth and was about to say that he was 99% sure, but he soon realized that he had fallen into the trap of the magic star, so he stiffened his neck and said, "As long as you don't move it in any way, I am 100% sure that it is positive!"
He believed in his own eyes, and even more in his own judgment...
However, Lynn shook his head in disappointment and moved his hands away. "Of course I didn't move it, but it's a pity that you guessed wrong!"
Guessed wrong?!
Jeffrey looked over in confusion.
The gold coin fell right in the middle of the table, in the tiny gap between two wooden boards!
"I forgot to say just now that there is still a very small probability that it will stand upright!" An obvious smile appeared at the corner of Lin En's mouth.
Jeffrey's eyes widened. He wondered if the magic star had secretly used some tricks at the last moment, but he couldn't say anything because there was indeed a possibility that the gold coin stood up! Lin En smiled and said nothing. He put the gold coin away. According to his promise, he did not interfere in any way after throwing the gold coin.
But this is certainly not due to luck!
His luck is not that good!
In fact, from the moment this gold coin was thrown, it was destined to fall into the gap!
Because he chose a force and angle to throw it that would fall into the gap from countless possibilities, so its fate was determined from the beginning.
He who tossed the gold coin was not only an observer, but also a promoter of fate...
At this moment, Lin En felt that he seemed to have realized something, and his understanding of the quantum field became deeper.
Although Lin En used a gold coin to explain what probability, choice and possibility are, it was obviously not enough to dispel the doubts of the wizards.
"This is different, this is different! If everything in the microscopic world is probabilistic and uncertain, then how do they constitute macroscopic matter? Will the flowers on the ground disappear if I don't go to see them?" Sanchez said in great confusion.
The other wizards also cited various examples to refute the argument, and the exhibition hall suddenly became noisy.
Fortunately, they do not understand what idealism and materialism are, otherwise they would have accused Lin of having very dangerous idealistic thoughts and would have been subject to criticism!
"How microscopic matter forms relatively stable macroscopic matter is a question worthy of in-depth study." Lin En nodded, and did not give a long explanation. Because if all the arguments were thrown out in one breath, it would probably be even more difficult for these wizards to accept.
Lin En only said that these issues will be explained in his upcoming new book [The World of Probability - Quantum Mechanics].
"Everyone, I need to remind you that it is our cognition that needs to conform to the underlying logic of the world, not the logic of the world's operation that needs to conform to our cognition!"
"This is very important!" Lynn said firmly.
The macroscopic world is certain and regular, and this certainty also makes it particularly difficult to understand the laws of the microscopic world.
The so-called probability waves and probability clouds are incredible and even contrary to common sense, but it must be said that it is indeed one of the underlying logics of how the world works.
There was once a great scientist, the most outstanding figure in the field of quantum, who absolutely did not believe that this world was probabilistic. But there is no doubt that he was slapped in the face. Whether it is the Federation's in-depth research and multiple innovations on the microscopic level over the past hundreds of years, or the many scientific research results on quantum, it can be proved that this world is so bizarre.
No, in a sense it is stranger than anyone could imagine!
"Okay, Speaker Lin, let's stop talking about the probability wave issue for now and discuss it later!" At the judges' table, Harov suddenly interrupted the debate about probability waves.
It's not that he didn't want to delve deeper. In fact, these legendary wizards were the ones who were most affected! Aurora's body was shaking like waves, as if it would collapse in the next moment. Although she finally stabilized, her face became very ugly.
She lost the ability to transform her energy body.
Or in other words, Aurora doesn't dare to use this ability, otherwise she will not be able to be sure whether her body will disintegrate or turn into a probability ball?
Vittorio was not much better. The more he thought about it, the more he began to question the nature of magic.
"Compared to the probability wave, I am more curious about the second question." Harov spoke slowly, his voice trembling slightly. "How do electrons know that we are observing them?"
As soon as these words were spoken, the entire exhibition hall fell into deathly silence.
They were so busy arguing about the probability wave that they indeed overlooked a very critical and even more terrifying question: how did the electrons discover that they were observing themselves and thus collapse into a single particle.
Arad once thought that it was due to the influence of magic in the field, but Lin En had ruled out this possibility.
Does this mean that the microscopic particles have self-awareness and can sense their observations, so they change their forms...
Thinking of this, Arad couldn't help but feel a chill on his back.
An elemental wizard suddenly seemed to have thought of something and shouted in fear, "I know, an elemental ghost, this is an elemental ghost!"
