"The observer effect!" At the same time, in the White Maple Palace in Antiffler, Thanos, who used to be the Sun King and was now Emperor Rudolf II, stood up from his throne and blinked to the display picture. His eyes were solemn and overjoyed.
At this moment, he seemed to have grasped the key to return to the level of demigod!
Although the experiment did not have double slits or beeping alarms but a brand-new design, through which the purpose of recording and erasing could be achieved, Douglas and Lucien had already demonstrated the equivalence of the two experiments in principle. According to Lucien, a lot of unnecessary "interferences" had been eliminated in the experiment so that the feeble "effect" would not be destroyed. Otherwise, Douglas wouldn't have had to wait until he became a demigod to carry out the experiment.
Therefore, any intelligent life with a bit of knowledge would tremble in shock. Could it be that "our" observation was the key to the disappearance of waves and the emergence of particles?
Was the world still objective and real?
Was it the observer effect that Lucien Evans proposed?
Before the experiment table, Douglas's raised hands were obviously shivering. It was obvious that he found the result unacceptable. However, everything was designed according to his vision and completed by him in person. There were no omissions or other influences. The result was real and trustworthy.
Lucien proposed the thought experiment for exactly the purpose of "proving" the observer effect!
Although other reasons other than the observer effect could not be ruled out, all the arcanists had to face the possibility of the observer effect seriously. At the very least, the observer effect could not be ignored anymore until other theoretical explanations were found!
Douglas stabilized his hands that were about to spread out and repeated the experiment again. The transformed interference fringes were still as clear as before.
Once, twice, thrice … After five times, Douglas raised his head and said solemnly and in a low voice, "The repeatability shows that the experiment result is correct. After today, the arcanists can apply to use the devices and repeat the experiment. "
There was nothing but dead silence in the stream room. Samantha, Louise, and part of the members of the Highest Council were still in disbelief and resistance. Most of the legendary sorcerers, including Brook, Fernando, Hathaway, Hellen, Oliver, and Vicente, were deep in thought. After the shock, they chose to consider whether or not they could find other explanations other than the observer effect.
In the Atom Institution, Annick shook his head and paced back and forth despite the broken glass under his feet. His mouth opened and closed silently, as if he were looking for other reasons. Sprint, on the other hand, stood there in a daze. There was no telling what was on his mind.
"The observer effect … Is there really an observer effect?" Heidi mumbled.
The design of this experiment was to highlight the existence of the observer effect, and the results clearly showed that this was the case.
In the generic schools and the noble schools, Ali looked at his classmates next to him. He seemed to be both asking them and asking himself. "It's impossible. If 'our' perceptions are the cause of everything, can the whole world still be objective and real? It doesn't fit the concept of arcana at all … "
The comparison of the experiments before and after revealed a terrifying conclusion.
"At the very least, it's caused by our own observation, not the gods. Our fate is still in our hands." Xia Lot, the monitor, replied subconsciously.
"Well … Well …" The students nearby were at a loss. They felt that all the arcana skills they had learned before had been overturned. What was right exactly?
On the stream screen, Douglas stopped being solemn and said gently and solemnly, "The quantum erasure experiment has been completed. Now, let's move on to the second and last experiment. Evans, delay the choice experiment. We still need to modify the traditional double-slit experiment so that the result can be better highlighted."
He replaced the double-slit experiment with another experiment and demonstrated the equivalence.
"The previous double-slit electron interference experiment let us know that if we choose the wave property and design the experiment based on it, what will appear in front of us in the end will be diffraction fringes. If we want to see the particle property and add a recording alarm, pure particle light spots will appear on the screen."
"At this moment, our choice and corresponding arrangement will lead to different results."
Douglas chose his words carefully. He still did not use "observer effect" but added "corresponding arrangement" to "choice".
The arcanists who watched the stream all nodded. Whatever the theory was, what Mr. President described just now was an objective fact. There was no problem at all.
Douglas continued, "What if we delay the choice? In the experiment, when the electron appears as the wave feature, it obviously passes through two slits and two paths at the same time, so it interferes with itself. When the electron appears as the particle feature, it will only pass through one of the slits and one of the paths. Then, what will happen if we make our choice before the electron reaches the screen? Will we see that the electron comes from two paths, or from one path? "
Because the double-slit experiment had been modified, Douglas did not use the double-slit experiment anymore but used paths.
"No matter what choice we make, the path of the electron has been determined before the choice is made, and it will not change …" Ali and the other ordinary people recovered from the shock caused by the erasure experiment the fastest. They began to judge the possible situation with their shallow arcana knowledge.
Annick shook his head and stopped himself from considering other explanations of the erasure experiment. Instead, he watched the experiment attentively.
The experiment that his teacher proposed was also related to the 'observer effect', but Annick did not think that the result that was in favor of the 'observer' hypothesis would happen. After all, whether the electron took two routes or one route had already been determined before the choice was made. It was not like 'observation' would lead to changes in the past, right?
In the Holy City, "Pope" Viken held back his previous delight and watched Douglas set up the experiment expressionlessly.
What was the experiment trying to prove?
He did not think that anything unexpected would happen. What should be shocking had been shocking just now. This experiment looked more like a refutation of a certain bold hypothesis.
Rudolph II sat on the throne in the White Maple Palace again and watched the picture of the experiment quietly. For some reason, he had a bad feeling.
The members of the Highest Council, Samantha, Louise and the rest of them in the broadcast room were also slightly confused. Was Lucien Evans trying to prove that the current observation could affect what had happened in the past? That was an idea that was even more unbelievable than turning back time!
The past had been determined. How could it be changed?
Douglas activated the experiment. The detector sent out a signal, and the electron came from one path.
The experiment was repeated time and time again, proving that the electron came from only one path after the previous steps.
Suddenly, when the electron finished the previous steps, before it reached the detector, Douglas quickly added a new experiment device, indicating that they wanted to choose 'wave'.
At this moment, the detector in the other direction and the detector in the current one beeped at the same time.
Douglas's face turned pale, because he knew very well what it meant!
It meant that after the choice was made, the electron that had determined that only one path came from two directions. What happened in the past had changed!
Our 'observation' had changed the electron's' past experience '!
Thud, thud, thud. Samantha stepped back and leaned against the wall. Her face was pale, and her eyes were wide open, with tears flowing out. Did it mean that the strict law of causality on the timeline did not hold? The reason could come after the result? The past could be changed now?
Pa, pa, pa. The magic notes and quills that the members of the Highest Council in the stream room were holding fell to the ground. The coldness and fear from the deepest part of their soul rendered them speechless. It was more unbelievable, marvelous, and unbelievable than any magic!
Even the grand arcanists such as Brook and Fernando were at a loss. How was it possible? Did the current choice determine what happened in the past?
Sounds of things being broken echoed in Allyn nonstop, but nobody said anything. It was like a city of silence.
Faced with such an experiment result, there was not a single arcanist who did not feel confused, that their worldview had collapsed, and that everything was like an illusion!
Many of them rubbed their heads, as if they were hoping that they could crush "it" so that they wouldn't feel so painful and desperate. If it weren't for the fact that their cognitive world was not involved, the ground would've been littered with corpses, blood, and brains. Few arcanists above the middle rank could've survived.
Even so, they still felt that their worldview had collapsed. They felt that they did not know this world anymore. There was nothing but gloom before their eyes.
Ali, Longman, and the other students who watched the stream found it even more unacceptable. They swallowed hard, unable to believe that the result would determine the process. It was completely against their common sense and instincts!
Nobody said anything anymore. They were all watching Douglas repeat the experiment.
Boom!
An intense explosion took place in the White Maple Palace in Antiffler. The most splendid and magnificent palace was reduced to ruins. In the middle of the ruins, Rudolph II, who was covered in wounds, mumbled to himself crazily, "Determinism, causality … causality, determinism …"
It was not until a long time later that he finally calmed down. However, he knew very well that he could only count on a miracle or Mountain Paradise under Viken's control if he wanted to return to the demigod level, because his worldview had completely collapsed.
As the most distinguished genius of the ancient Magic Empire and the first expert to find the path of demigod in history, 'Sun King' Thanos truly understood what a 'worldview destroyer' was!
In the Holy City, Viken was equally confused and in disbelief at first. Then, he burst into crazy laughter. "The observer effect. Reversing the law of causality on the timeline and changing the past from the present. I get it now! I get it now!
