My girlfriend died in the past

Chapter 242 Waiting for the rabbit
At this moment, Zhuang Xiao and the other two were listening to Gu Shiyue's "lecture" like obedient primary school students.

Zhuang Xiao even raised his hand and said, "Teacher Gu, can you explain it in a simpler way? We don't quite understand."

Gu Shiyue tilted her head and said, "Well, I will say it in a way that even an idiot can understand."

Zhuang Xiao and the other two: “.”

As expected of Gu Shiyue, she can easily say such unemotional words!

The key is that she is particularly convincing!

Gu Shiyue thought for a moment, her brows slightly furrowed.

It seemed as if it was difficult for her to explain things simply.

After all, to her, a lot of so-called "incomprehensible knowledge" is just "simple principles that even elementary school students understand."

After a little hesitation, she spoke, "The so-called Schrödinger's cat refers to..."

"Teacher Gu." Zhuang Xiao raised his hand, "We still understand this."

Schrödinger's cat is often referred to as "Schrödinger's hypothesis".

It means a cat, a bottle of poison and a radioactive source are placed in a sealed box.

If the detector inside the box detected radioactivity, the flask would shatter, releasing poison that would kill the cat. When people opened the box, they would see the cat either alive or dead.

However, "Schrödinger's Cat" was originally a criticism of the quantum mechanics theory proposed by another big shot.

According to that big guy, before the box was opened, the cat inside should theoretically be in a superposition state of both alive and dead.

And cats, as living things, are either alive or dead.

Therefore, Schrödinger proposed this theory to prove the absurdity of the other party's theory.

"So Mr. Gu, you mean that Xiaodie is in a superposition state of existence and non-existence?"

"Not all of them, just similar situations."

Gu Shiyue tilted her head, "Zhuang Xiao, have you ever seen two Xiaodie appear in front of you at the same time?"

Zhuang Xiao recalled, "It seems that there really isn't one."

"That's it." Gu Shiyue concluded: "The theory of 'shadow world' is correct, but it is still biased."

Dong Zeyu complained: "But you were the one who proposed it."

"At that time, I didn't know." When facing people other than Zhuang Xiao, Gu Shiyue returned to his concise and to the point mode.

Zhuang Xiao explained for her, "Because Yueyue didn't know the specific situation on my side at that time, she only knew the general situation, so now you have a new theory?"

Gu Shiyue nodded, "Originally I thought that there should be nothing in the 'shadow world', but because you and An Lan went back to the past and caused the future to be unable to continue, they are living in those cracks. To be precise, they are just some kind of 'possibility' of the future.

"But now it seems that this is not the case. Perhaps the 'shadow world' is in a superposition state with our real world, but it cannot be observed or touched normally. Because of you and An Lan, a 'hole', or a 'channel', has appeared in the membrane that was originally absolutely impossible to break."

Speaking of his expertise, Gu Shiyue couldn't help but say a lot more, "This is also the reason why the four 'channels' you discovered are in a superposition state."

Zhuang Xiao was shocked. "So you mean there are countless little butterflies everywhere? Maybe they are watching us from all sides right now?"

"What the hell?!"

Dong Zeyu was so scared that he jumped up and looked around.

Even though there was no one around and it was still daytime and even sunny.

But he always felt that there was something dirty hidden in the weeds around him.

"Do you have to be so scary?!"

"Not really." Gu Shiyue's tone remained calm, "The two sides usually don't interfere with each other. But the original idea may not be accurate. They don't enter and exit the 'shadow world' through a place like a door.

"If it is really a superposition state, the reason for her appearance is more due to 'observation'." "Observation?" A question mark floated across Zhuang Xiao's head.

"Yes, and it's your observation." Gu Shiyue became a little excited as she spoke, and even spoke faster, "Before you entered the house, she was in a superposition state, and she appeared after you appeared.

"Whether it's the short-haired Fluttershy in the hat you mentioned, or the Fluttershy in the skirt, or the Fluttershy in the pajamas and the Fluttershy with permed hair, it's all because of the same reason.

"They were just doing their own things in the 'shadow world', but because you 'observed' them, they instantly appeared from the 'shadow world' into the real world.

“At the same time, the real Xiaodie is still in the capital.

"That is to say, multiple Xiaodie can appear at the same time, but she will only appear under your observation. This is why only one Xiaodie can appear at a time."

Dong Zeyu had already fainted after hearing this, and his small green eyes had become the shape of mosquito coils.

Dong Weirui listened carefully, so she asked a question, "But how did the body appear? And the mosaic figure captured by the surveillance camera. Oh, and the person who called the police."

"Because multiple Xiaodie exist at the same time, just not in the real world, but those things are happening." Gu Shiyue answered.

Zhuang Xiao frowned, "But the problem is that I didn't see them. At least the person who called the police and the deceased were there before that."

He was referring to before "time went back".

"It's a very simple principle. This so-called 'observation' does not mean that you see it, but that you have corresponding thoughts and ideas, and you are near the 'channel', so this situation is triggered.

"Of course, you don't have to worry, because according to the currently known information, they will only appear from the 'channel'." Gu Shiyue concluded.

Zhuang Xiao thought about it and it seemed to be true!
The last time Dong Weirui called before "Time Travel" was because he was playing games with Dong Zeyu at home, and then he felt too bored, so he wanted to ask Dong Weirui when he would come over.

At that time, he subconsciously thought that something might have happened.

As a result, the police received a call and found the charred body.

When Zhuang Xiao arrived at the scene, he found that it was a copy of the surveillance video. He wondered "will the surveillance video capture anything?" and then the mosaic figure really appeared.

After he got home, he thought about Xiaodie saying she would be back in a few days but didn't say the specific time, and wondered if she would give him a surprise or something.

Then Shudie with short hair and a hat appeared at home as expected.

After she went out to buy drinks, more than ten minutes later, Zhuang Xiao thought she should be back.

Then the girl in the skirt, Shudie, appeared.

This is even more true later.

After returning home from the scene, he thought Shudie should still be waiting for him, and then Shudie in pajamas appeared.

The next day at noon, he thought Shu Die should come back for lunch.

Then Shudie, the girl with permed hair, pushed the door open and came in.

But there is still a problem.

"But the surveillance video should have captured what happened at 18:44 in the afternoon. At that time, I hadn't thought about the surveillance video. How can I explain this?"

Gu Shiyue gave the answer, "Things have been happening all along, just not in the real world, including Shudie's return home, which is also a real return home.

"It's just that you were thinking about related things near or inside the 'channel', so the things in the 'shadow world' that were originally unobservable were released from superposition and appeared in the real world."

Gu Shiyue concluded: "This is what I call 'Schrödinger's Shudie'."

Zhuang Xiao and the other two probably understood.

Then he asked, "So what should we do now?"

"Just sit back and wait." Gu Shiyue showed a sick smile like a mad scientist, "I'll fly back now. When I come back, we'll catch a little butterfly."
