Chapter 538 Causal Reversal, Delayed Choice Double-slit Experiment

  King Capital, Magic Research Institute, Microcosmic and Quantum Laboratory.

  A dozen great wizards gathered here to conduct a new round of double-slit interference experiments.

  Although as early as a few months ago in the academic seminar, Lynn will conduct a similar experiment, and use the undisputed experimental results to prove that quantum has both wave and particle properties.

   But this result is really unacceptable. First of all, this so-called probability wave is completely contrary to common sense and almost overthrows the foundation of the entire magic science!

  How can the world be random?

  Truth can never roll the dice all the time!

  As for the observer effect, it brings quantum theory to a very weird situation. Human consciousness can have a decisive impact on quantum phenomena, or microscopic particles are conscious and can perceive their observations.

  This theory has made many great wizards who study microscopic theory feel unbelievable, so many people suspect that the so-called probability wave and observer effect are concepts fabricated by the magic star in order to explain the phenomenon.

  It’s like before the theory of the planet was born, they all firmly believed that the continent under their feet was flat, and the sun, moon and stars were revolving around the continent.

   In fact, this is just taking appearances as reality, so quantum theory must be the same!

  In order to verify this conjecture and stabilize the foundation of magic that is about to collapse, these fifteen great wizards who have made great achievements in the microscopic field decided to improve the double-slit interference experiment.

  Among these people are former scholars of the Particle School, as well as founders of the Wave School like Jeffrey.

  Many people were very unhappy in the scolding battle a few months ago, and almost started a fight on the spot, but now they have put aside their previous suspicions and united together, preparing to test the authenticity of quantum theory together!

  As for the measurement methods, there are also various methods, full of brain holes and whimsical ideas, but in general it is to work **** the opposition of waves and particles.

   The most troublesome thing for the great wizards is the problem of detecting the path of microscopic particles. Fortunately, with the gradual opening of the magic net, this problem has also been solved to a certain extent.

   These great wizards have the opportunity to mobilize the computing power of the Magic Network three times a week, each time for ten minutes, fifteen people is four hundred and fifty minutes!

   Must be economical, which is why they chose to get together instead of studying alone.

   "No. 27 double-slit interference experiment test is normal!"

  Jeffrey, who was in charge of the experiment, quickly adjusted the steps of the experiment. The goal of their experiment this week is very clear, that is to verify whether the observation can have an absolute impact on the transformation of the wave-particle properties.

  Jeffrey’s idea is also very simple. Since the electrons are generated when they pass through the double slit, why not wait for the electrons to pass through the double slit first, and then probe in the second half, what will happen?

  Because they did not observe the first half, the electrons should not know that someone is observing themselves, and maybe they will show a wave form and be caught by them!

While explaining his idea, Jeffrey installed the electron accelerator. The conception and experiments over the past few months have cost him a lot of effort. He has done many similar experiments before, but due to the difficulty of observation, Haven't been able to get great results.

And today there will definitely be an answer, and Jeffrey is extremely firm about it—he has waited for too long. Last time in the City of Fire Oil, after witnessing two colleagues being swallowed by a terrifying energy wave, his fear of quantum phenomena was like A nightmare generally enveloped his heart.

  Jeffrey knew very well that if he didn't solve this problem, he might never dare to step into the formation of being promoted to legend!

   "Everyone, let's get started!" Jeffrey took a deep breath, adjusted his mentality, and then opened the magic net.

  An invisible magic field enveloped the audience, and Allard and others on the side also connected to the magic net one after another, using the function of shared perception.

  The electron accelerator was quickly activated, and one after another the accelerated electrons flew towards the middle partition at an extremely fast speed.

   Jeffrey was concentrating on it, his mind was extremely tense, and the rest of the great wizards did not dare to be distracted in the slightest.

  Because the accelerated electrons fly very fast, it is difficult to detect even with the reaction speed of the great wizard.

   "Particles, yes particles!"

  Almost at the moment the accelerator was activated, a great wizard shouted loudly, and a light spot was already lit behind the partition.

   Then another "particle" of electrons was shot out, this time everyone felt it, and the disturbance of the electromagnetic field was extremely obvious!

"This shouldn't be right!" Jeffrey frowned suddenly, and after waiting for more than a minute, hundreds of electrons were fired. As a result, these electrons honestly passed through a single gap in the form of particles. .

   This is completely different from what he imagined.

   "Could it be that the distance is too close? Or try to go farther away?" Sanchez said ponderingly.

In order to better capture how a single particle appears in multiple locations at the same time in the form of probability waves, interferes with itself, forming several fringe-like interference spots, which are used to detect the magic power field, which has almost been pasted on the partition. Just to capture the moment.

  Jeffrey hesitated for a moment, then accepted the guess, and pushed back the perception field by five centimeters. The result was still the same. Then he gritted his teeth and pushed back another ten centimeters, only less than one centimeter away from the perception screen.

  In this state, they can only slightly capture the trajectory of the electrons, and cannot tell which gap the other party has passed through, let alone how the electrons passed through the two gaps.

   But even if this level has been achieved, there are still only two clear light spots reflected on the rear fluorescent screen, which shows that the electrons are honestly in the form of particles and passed through a gap.

   "Why... why does it know that we have set up perception magic in the rear?" Jeffrey muttered to himself, puzzled.

   "Perhaps the scope of the domain is too large, and the electronics sensed the fluctuation of magic power, so exploration took place!" Sanchez guessed again. "It's also possible that the particle passed through the gap in the form of a probability wave before, but after entering the domain, it collapsed into a particle state again!"

   "How is this possible?" Jeffrey frowned. "If it is still in the form of a probability wave when it passes through the crack, then interference has already occurred, and there must be light spots that deviate from the area on the screen..."

  The rest of the great wizards also nodded, so there is only one possibility, the electron has already made a choice the moment it passed through the crack!

  Jeffrey was extremely sure but unwilling to believe this guess, so he moved the perception field back by one centimeter again.

   At the moment when the magic field just left the surface of the perception screen, eye-catching bright spots appeared beyond the landing point of the two light spots, which meant that the path of electron movement was interfered again.

This discovery shocked Jeffrey and the others. They only felt a chill rising from their backs. The electrons actually realized at this moment that their path would not be perceived, and then retransformed from certain particles. For probability waves…

   "Why... why can it know whether we have set up perception magic behind the crack?" Jeffrey muttered to himself, his face extremely ugly.

   "Is it possible that it saw the perception field ahead through the gap?"

For them, the magic field of sensing the electromagnetic field may be invisible, but it is possible that from the perspective of electrons, it is a huge solid wall, so at the moment it is fired by the thermal field electron gun, it sees the front The field of perception changed immediately.

   This guess is undoubtedly a bit outrageous, not only does it mean that electrons are conscious, able to perceive their perception, and also have a certain degree of vision.

"Impossible, Chairman Lynn has already experimented on this point. If a magic field is simply constructed without choosing to observe, electrons will still pass through the two gaps at the same time in the form of probability waves, and interference fringes will appear in the rear. So it can't be a problem in the field of perception." A great wizard of the particle faction objected.

"Then you mean, did the electron predict that we would observe in advance? That's why it transformed into a particle state in advance, is that so?" Sanchez shouted rather irritablely. This judgment is more perceptive than the electron Outrageous!

  This is not only a serious violation of common sense, but even a violation of causality!

   Either electrons can see the future, or this thing can change the past!

   "I've already said that your method won't work, Jeffrey!" Allard said mockingly. In his opinion, such a weird result affirmed that there was a serious problem in the experiment designed by Jeffrey!

   "You can, come here!" Jeffrey stepped aside and looked at Arad with a sneer. He wanted to know what tricks the other party could come up with.

   "My method is actually very simple..." Allard cleared his throat, and took out a box more than half a meter high under everyone's gaze!

   "What is this thing?" Sanchez immediately thought of something.

   "Do you still remember Professor Lynn's quantum cat?" Allard smiled triumphantly.

   "You mean the concept cat between life and death?" Jeffrey's face twitched involuntarily. Of course, he will not forget that weird thought experiment.

  Although Lynn just proposed this concept and didn't really put it into practice, it still made him remember it fresh.

"That's right, this is the device I modified based on the cage where Speaker Lynn imprisoned the quantum cat. I specifically asked Speaker Vittorio to solidify a magic that can monitor the trajectory of electrons in the device, and its switch It's completely random!"

   Jeffrey suddenly felt his eyes light up, and the dissatisfaction on his face immediately decreased a lot.

  Let's not talk about electrons now, even they themselves don't know when the instruments that record the electron path will be turned on and when they will be turned off.

  Sanchez even proposed that they make the path long enough and distorted enough to further affect the judgment ability of electrons.

  Allard readily accepted this suggestion, and started a new round of experiments with full confidence, which is bound to decipher the secret of the trajectory of microscopic particles!

   After half an hour, the experiment was undoubtedly a complete success!

   Nine of the fifteen great wizards present went crazy!

  Such a major experimental accident naturally alarmed the parliament immediately.

  However, together with this delayed choice double-slit interference experiment, what detonated the circle of wizards is the theory of relativity just published by Lynn.

  There are four formulas in it—relative velocity formula, relative length formula, relative mass formula, and relative time formula.

   And the two most core theories.

  The first is the principle of relativity. All inertial reference frames are equal, that is, the form of physical laws is the same in any inertial reference frame.

  This theory is a bit brain-intensive, but it is not incomprehensible. When Lynn explained the planetary theory, he mentioned that any movement is relative, only the frame of reference is different.

  This time I just made some extensions. Any inertial reference frame is equal, and there is no one inertial reference frame that is superior to other inertial reference frames.

  The second is the law of constant speed of light—the propagation speed of light in vacuum in any reference system is always a constant value!

   "Absurd! How can the speed of light be constant!" The congressman who was studying optics couldn't help but slapped the manuscript on the table.

  He thought that the quantum probability wave of the magical star was outrageous enough, but he didn't expect that now the other party actually proposed an even more outrageous theory of constant speed of light.

   Make a simple thought assumption and you will know that if two people release laser beams back to back, and take one of the laser beams as the reference frame, then the speed of the other laser beam must be moving away at twice the speed of light!

   This is also in line with Lynn's own frame of reference theory.

   According to the law of constant speed of light, from any angle of view, the speed of light is 300,000 kilometers per second, and there will be no change!

And those relative formulas regard the length and mass of an object as a changing value. For example, a stick is three centimeters and weighs one kilogram in a static state, but if it moves, the length and mass will also change accordingly. changes happened.

The length will decrease as the relative speed increases, the mass will increase as the speed increases, and even time will slow down as the speed increases, all these changes will increase to the maximum threshold when reaching the speed of light !

"According to this statement, there is nothing determinable in the whole world, and the quality and length will change, so what is the eternal truth? What's the point of the development of magic?" the congressman roared. Said.

  In the research room, the rest of the great wizards who received the manuscripts of the theory of relativity could not accept such a strange theory, and spoke one after another.

"Where is Speaker Lynn now? Is he still in the capital?" "I demand that an academic conference be held now!" "It's hard to imagine that such a thing would be written by that magical star. It’s a product of contradictions…”
