Liang Jing came back from going to the toilet.

"Lou Qi! Has the computer been repaired......?"

Liang Jing was stunned, the P3 lab was empty, he turned on the computer on the table, and the monitor had returned to normal.

It seems that I repaired the computer and went back.

This kid is really good at work.

He picked up the filter glasses that had fallen on the ground, looked left and right, and put them on the cabinet, wondering, when did these glasses fall to the ground?

"Big White?" Liang Jing noticed that all the instruments in the laboratory were turned off, and even the power of the microscope was cut off, "Dabai, where are you?" What's the power outage in the lab? ”

"Mr. Liang Jing, I'm here." Da Bai came back, "I noticed that Mr. Lou Qi is not by your side, where is he?" ”

Liang Jing was stunned.

"You ask me? Didn't he go out? ”

"No, Mr. Liang Jing." Dabai said, "Mr. Lou Qi has never left this laboratory. ”

Liang Jing was stunned for a moment.

"What did you say?"

.

"You see, he entered the P3 lab at this time, and the time was 13:22 p.m." Wan Kai pointed to the time number on the image.

In the surveillance footage, everyone can see a young man coming out of the elevator and entering the P3 lab through the corridor on the first floor, Wan Kai zooms in and flips the image so that others can see his face, a pair of trademark collapsed eyebrows, looking listless - yes, it's Lou Qi, at 1:20 this afternoon, he was approached by Liang Jing to fix the computer in the lab.

Next, the surveillance image switched, and Liang Jing in the P3 laboratory stood in front of the glove box like a hemp bag, and he beckoned to Lou Qi - the real Liang Jing was sitting on a chair at this time, watching himself in the surveillance repeat his actions ten minutes ago.

"This is a beam worker." Chef points to the people in the lab.

Liang Jing nodded.

"This is Lou Qi." Chef gestured to the door of the lab.

At this time, both of them were wearing sealed protective clothing, and their figures and appearances were no longer visible.

Under the gaze of everyone around, Liang Jing in the monitoring turned on the computer on the table, Lou Qi walked straight over, and the former gave up his position and let Lou Qi sit on the chair.

"I asked him to come and fix the computer." "Then I went out to the toilet." ”

As soon as he finished speaking, everyone saw Liang Jing under surveillance hurriedly going out, taking small steps in the figure-in, it seemed that he had been holding back for a long time, and only Lou Qi was left alone in the laboratory.

All the members of Cassini Station were concentrated in the hall, surrounding the surveillance video, and everyone stared at the figure in mid-air, not daring to blink their eyes, for fear that he would evaporate from the world in the next second, like a mermaid turning into a bubble.

The upstairs on the screen sit down to fix the computer, and so far everything is fine.

"According to Dabai, Lou Qi disappeared when observing the black ball in the infrared band, why did this happen?" Jiang Zi asked, "He doubts that the wave function of the black ball will not collapse when there is no observer?" What does that mean? Which of you will explain? ”

Mo Yu and Chef looked at each other, they were not from physics, and they were confused about this thing.

"You all know wave-particle duality, right? The theory that electromagnetic waves are both particles and waves can actually be further expanded. Among all the people present, only Liang Jing leaned on the side, and he could only stand up and explain, "To put it simply, in the microscopic state, not only photons, but all the elementary particles we know exist in the form of waves, and they are probability waves, including you and me, you and I are all waves...... I'm not studying this either, that's pretty much what it means. ”

Am I Wave? Jiang Zi frowned.

Then my wave may be bigger than yours.

Silent said.

"Lou Qi's idea may be this, he thinks that this black ball is unobservable, so its wave function cannot be determined, and it will not collapse." Liang Jing continued, wondering as he spoke, "But how is this possible?" His idea is utter nonsense...... The black ball is a macroscopic object, and in the macrocosm this effect should be negligible, and it is impossible to do so, although all of us are theoretically the result of the collapse of probability waves, but on the scale of our daily life, we can say that something does exist. ”

"Yes." Dabai said, "That's what Mr. Lou Qi told me at the time, he thought that observing the black ball in the infrared band would change the object of observation, and asked me to leave the laboratory for this reason. ”

"What happens if the wave function doesn't collapse?" Asked silently.

"If the wave function doesn't collapse, then in our eyes, it doesn't actually exist." Liang Jing glanced at her, "It may be distributed in every corner of this universe. ”

"You're saying the black ball will disappear?" Asked silently.

"The disappearance in our eyes, of course, is based on the premise of treating the black ball as a microscopic particle." Liang Jing replied, "I still want to emphasize that this phenomenon cannot exist in the macrocosm, you put an apple in a box, the apple will not disappear and fly away because you don't look at it, the microcosm is different from the world we usually live in, they follow another set of rules, such as Heisenberg's uncertainty principle, you can't measure the speed and position of an elementary particle at the same time, but in the macrocosm, we can measure the speed of a car and know its position, Therefore, it is inappropriate to use the rules of the microcosm to discuss the problems of the macrocosm. ”

"Ever since the appearance of this black orb, your scientific experience has begun to fail." Tache pointed out the problem pointedly, "If even the most basic thermodynamics can be violated, then what else is impossible?" ”

Liang Jing was silent.

Indeed, from the moment this black ball appeared, the set he had learned in the past began to be frequently challenged.

But quantum mechanics itself is a freak, and compared to the damn counterintuitive theory of quantum mechanics, the black ball is a little more elusive.

Compared with quantum mechanics, he prefers to stay with the black ball, Liang Jing thought very highly of himself back then, ignoring the teacher's earnest teachings of "just be able to calculate, don't understand", deeply entangled in quantum mechanics, trying to understand it, and almost depressed, and finally decisively turned to chemical physics and structural physics, so as not to ruin his future and life.

"But the black ball didn't disappear, and it was Lou Qi who disappeared last." Jiang Zi said, "You mean that Lou Qi wanted to observe the black ball disappearing, but he disappeared himself?" ”

"Judging by the results...... Liang Jing nodded, "That's right." ”

In the surveillance image, Lou Qi stood five meters away from the glove box, put on his glasses, and raised his hand to make an OK gesture - it was the last image he left in this world.
