Chapter 538: Causal Reversal, Delayed Selection of Double-Slit Experiment

Royal Capital, Academy of Magic, Micro and Quantum Laboratory.

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

Although a few months ago, at an academic symposium, Lynn would have conducted a similar experiment and proved with indisputable results that quantum has both wave and particle properties.

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

How can the world be random?

Truth can never be rolling the dice all the time!

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

This theory has been so unbelievable to many great wizards who study microscopic theories that many people suspect that the so-called probability waves and observer effects are concepts that the magic star made up out of thin air in order to explain the phenomenon.

It's like before the advent of the planetary theory, 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 nothing more than taking appearance for reality, so quantum theory must be the same!

In order to test this conjecture and stabilize the foundation of magic that was about to collapse, the fifteen great wizards who had made great achievements in the microscopic field decided to reimprove the double-slit interference experiment.

Among these people are former scholars of the particle school, and there are also founders of the wave school like Jeffrey.

Many people had a very unpleasant scolding war a few months ago, and almost fought on the spot, but now they have put aside their previous suspicions and united together, ready to determine the authenticity of quantum theory together!

As for the measurement methods, there are also a variety of brainstorms and whimsical ideas, but in general, they are working on fluctuations and the opposition of particles.

The biggest headache for the great wizards is the exploration of the path of microscopic particles, but 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 net three times a week, each time it takes ten minutes, and fifteen people have four hundred and fifty minutes!

You have to be sparing, which is why they choose to get together instead of studying individually.

"The twenty-seventh double-slit interferometry test is all right!"

Jeffrey, who was in charge of the experiment, quickly adjusted the steps of the experiment, and this week the goal of the experiment was clear: to verify that the observations could have an absolute effect on the transformation of the properties of the waveparticles.

Jeffrey's idea is also very simple, since the electrons occur when they pass through the double slit, what happens if they wait for the electrons to pass through the double slit first, and then probe in the second half?

Because they didn't observe the first half, the electrons should not know that someone was observing them, and maybe they would show a wave pattern and be caught by them!

Jeffrey explained his idea as he put in the electron accelerator, which had taken a lot of effort over the past few months, and he had done many similar experiments before, but he had not been able to get good results due to the difficulty of observation.

Today there will be an answer, and Jeffrey is adamant about itβ€”he's been waiting too long, and the fear of quantum phenomena has gripped him like a nightmare after witnessing two of his colleagues being swallowed up by terrifying energy waves in the City of Fire and Oil.

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

"Guys, let's get started!" Jeffrey took a deep breath, adjusted his mindset, and then opened the magic web.

The invisible magic realm enveloped the audience, and Arad and the 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 great speed.

Jeffrey was so engrossed that his mind was tense to the extreme, and the rest of the great wizards didn't dare to be distracted in the slightest.

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

"Particles, they're particles!"

Almost as soon as the accelerator was activated, a great wizard shouted loudly, and a point of light was already lit up behind the partition.

Then another "one" electron was ejected, and this time everyone sensed it, and the disturbance of the electromagnetic field was extremely obvious!

"This shouldn't be right!" Jeffrey's brows furrowed suddenly, and he waited for more than a minute and fired hundreds of electrons, which all honestly passed through a single crack in the form of particles.

It was completely different from what he imagined.

"Could it be that it's too close? Why don't you get farther away and give it a try? Sanchez said with a deep groan.

In order to better capture how a single particle appears in multiple locations at the same time in the form of probability waves, it interferes with itself to form several striped interference spots, which are used to detect the magic field and almost have been pasted to the partition, in order to capture this moment.

Jeffrey hesitated for a moment, then agreed to this guess, and pushed the perception field back by five centimeters, the result was still the same, and then gritted his teeth and pushed back ten centimeters again, only less than a centimeter away from the perception screen.

In such a state, they can only slightly capture the trajectory of the electron, and cannot judge whether the other party passed through the gap, let alone how the electron passed through the two gaps.

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

"Why...... Why does it know we're going to have sentient magic in the rear? Jeffrey muttered to himself, puzzled.

"Maybe the scope of the field is too large, and the electrons sense the fluctuations of the magic power, so the exploration happens!" Sanchez guessed again. "It's also possible that the particle passed through the crack in the form of a probability wave before, but after entering the realm range, it collapsed back into a particle state!"

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

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

Extremely sure but unwilling to believe the speculation, Geoffrey shifted the perceptual realm back a centimeter again.

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

This discovery made Jeffrey and the others feel a chill rising from their backs, and the electrons actually sensed that their paths would not be perceived at this moment, and then reconverted from certain particles to probability waves......

"Why...... Why does it know if we've set up sentient magic behind the crack? Jeffrey muttered to himself, his face extremely ugly.

"Is it possible that it saw through the gap into the realm of perception that lies ahead?"

For them, the magical field of sensing electromagnetic fields may not be visible, but it is possible that in the eyes of electrons, it is a huge wall, so the moment it is fired by the thermal field electron gun, it sees the field of perception in front of it, and then it changes.

This speculation is undoubtedly outrageous, not only because it means that electrons are conscious and able to perceive their perceptions, but also have some degree of vision.

"Impossible, this Speaker Lynn has already experimented, if you simply construct a magic field and do not choose to observe, the electrons will still pass through two gaps at the same time in the form of probability waves, showing interference fringes in the back, so it is definitely not a problem in the field of perception." A Grand Wizard of the Particle Sect objected.

"Do you mean that electrons predict our observations in advance? That's why it transitioned into a particle state in advance, right? Sanchez shouted in a rage, this judgment is even more outrageous than the ability of electrons to sentience!

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

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

"I said it a long time ago, you can't do it, Jeffrey!" Arad said mockingly, in his opinion, such a strange result would occur, and it was certain that there was a serious problem with the experiment designed by Geoffrey!

"You can, come on!" Jeffrey stepped aside and looked at Arad with a sneer, he wanted to know what the other party could do.

"My method is actually very simple......" Arad cleared his throat and took out a box more than half a meter high under the gaze of everyone!

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

"Do you remember Professor Lynn's quantum cat?" Arad smirked.

"You mean the concept cat that is somewhere between life and death?" Jeffrey's face twitched, and of course he wouldn't forget that weird thought experiment.

Although Lynn only came up with the concept and didn't really put it into practice, it still stuck in his memory.

"That's right, this is the device I modified from the cage where Speaker Lynn held the quantum cat, and I specifically asked Speaker Vittorio to solidify a magic inside the device that can monitor the trajectory of electrons passing through, and its switch is completely random!"

Jeffrey's eyes lit up, and the look of dissatisfaction on his face immediately diminished.

Now let alone electronics, even they themselves don't know exactly when the instrument that records the path of electrons will turn on and off.

Sanchez even suggested that they make the path long enough and twisted enough to further affect the electron's ability to judge.

Arad gladly accepted this suggestion and confidently began a new round of experiments, which is bound to crack the secret of the trajectory of microscopic particles!

Half an hour later, there was no doubt that the experiment was a complete success!

Nine of the fifteen archwizards present went crazy!

Such a large experimental accident naturally alarmed the parliament at once.

However, along with this delayed choice of double-slit interference experiment, the wizarding circle was also detonated by Lynn's theory of relativity, which had just been published.

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

and two of the most central theories.

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

This theory is a bit brain-burning, but it is not incomprehensible, as Lynn mentioned in his exposition of the theory of the planets that any movement is relative, only the frame of reference is different.

This time it is only an extension, and all inertial frames of reference are equal, and there is no one inertial frame of reference that is superior to other inertial frames of reference.

The second is the law of invariance of the speed of light - the vacuum propagation rate of light in any frame of reference is always a constant value!

"Ridiculous! How can the speed of light be constant! The councillor, who was studying optics, couldn't help but slap the manuscript on the table.

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

If two people release a laser beam with their backs to back, using one of the laser beams as a reference frame, then the speed of the other laser must be moving away at twice the speed of light!

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

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

For example, a stick is three centimeters at rest and weighs one kilogram, but if it moves, the length and mass will also change.

The length decreases as the relative velocity increases, the mass increases as the speed increases, and even the time slows down as the speed increases, all of which are raised to the maximum threshold when the speed of light is reached!

According to this statement, there is nothing in the whole world that can be determined, and the mass and length will change, so what is the eternal and unchanging truth? What is the significance of the development of magic? The councillor said with a roar.

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

"Where's Speaker Lynn now? Is he still in the royal capital? "I ask for an academic conference to be held now!" "It's hard to imagine that such a thing could have been written by that magic star, and this quantum theory of relativity is the product of complete contradictions......"
