"Don't forget ......"

"I'm from 2023."

This sentence was like a heavy hammer, and it suddenly hit Pan Lishan's heart.

He looked at Lu Yun in amazement, Tong Kong shrank, looking extremely incredulous.

But at the same time of disbelief, he was willing to believe it in his heart......

This is not a contradiction.

Especially when it comes to a young quantum mechanics scholar, it seems to be a matter of course.

Time travel has a great temptation for Pan Lishan.

But he was still cautious.

I didn't know how to speak for a while.

He doesn't know what kind of attitude he should show in order for the other party to understand the state of his heart.

And Lu Yun didn't need him to show any attitude......

He was well aware of Pan Lishan's psychological state at this moment.

Taking advantage of his wandering at this time, Lu Yun continued to speak:

"Since I'm from 2023, I'm naturally burdened with a task."

"In order to ensure the stability of time and space, I have been asked not to reveal too much information."

"I want to ......"

"You should be able to understand that."

These are the arguments that ensure the stability of time and space......

Of course, Lu Yun made it up.

But the effect is outstanding.

Because as soon as Lu Yun's words landed, Pan Lishan obviously swallowed, and his lips turned a little white.

Pan Lishan also understood these words as a matter of course, his heartbeat was accelerating, and his heart was extremely shocked.

He stripped away all external factors, and immediately thought of the most important part of Lu Yun's words:

"He's someone sent by the state in 2023?"

For Pan Lishan, everything Lu Yun showed at this time made him extremely curious and excited.

When he thought that it was the country that needed him, that sense of fate and mission haunted him at this moment.

What's more, it's his infinite vision for his future.

It's a wonderful feeling to be so trusted and valued.

Still, he was on the most basic of alertness.

He knew he couldn't just believe it, because the other party didn't come up with any substantial evidence.

He frowned, then asked cautiously:

"How do you prove that you're from the future?"

Lu Yun's expression was serious, and he emphasized again:

"As I said, I was asked not to divulge too much information."

"I think you should know better than me what the consequences of future items will be when they appear in front of you."

"I know you're having a hard time believing it."

"That's why I'm in 1995."

"That's part of my mission."

Lu Yun's answer not only did not disappoint Pan Lishan, but aroused his interest even more.

Of course, he can understand that the early appearance of future objects will make the future full of uncertainty.

So, he lowered his head and pondered at the moment.

I was thinking about how I could verify whether this young man was from the future.

Soon, he looked up and asked:

"What does the result of the delay experiment depend on for the double-slit interference experiment?"

He looked at Lu Yun with blazing eyes, with great anticipation in his eyes!

The quantum physics I have studied is the most cutting-edge existence in the world and even in all mankind, and in recent years, there have been experiments on quantum physics that are gradually breaking through the original imagination!

If the other party is really from 2023......

If the other party really came here to cooperate in experiments......

Then this question should be easy to answer!

However, when this question was asked, Lu Yun's heart was relieved.

By coincidence......

This is a question he knows how to answer.

Pan Lishan never dreamed of it......

The question he asked has been played badly by the marketing account.

At this time, Lu Yun still maintained the seriousness that a future agent should have.

He opened his mouth to answer Pan Lishan's question.

"It depends...... Observations or not. ”

Hearing Lu Yun's answer, Pan Lishan immediately nodded in surprise to indicate that his answer was correct.

However, this question is only a starting point, and he intends to continue to ask it, and of course the difficulty of the question will gradually increase to verify whether he is from the future.

So, he bowed his head and fell silent, and began to think about the question he was going to ask next.

But Lu Yun quietly took a deep breath.

Everything related to the double-slit interference experiment flashed through the brain for a moment.

……

Here's how it works......

In the 19th century, because of the debate about whether light is a wave or a particle, the double-slit interference experiment began.

As a result, it caused an earthquake-like violent tremor in the physics community at that time!

Whether the light will appear as a particle or a wave depends on the observation!

Observations can make a difference!

If photons are not observed, the light will appear as waves.

If a photon is observed, the light will appear as a particle.

Observing and not observing, there are two completely different answers!

Later, Einstein explained this result with "wave-particle duality", which is also mentioned in the sophomore textbook, which led to the equation of E=hv.

However, in 1979, a delayed selection experiment based on a double-slit interference experiment once again launched an absolute challenge to classical physics!

The "observer" that will observe the photons moves from before the double slit to the screen before the final result.

It stands to reason that if light is not observed by an observer before passing through the double slit, then it should present the properties of a wave.

But the conclusion was completely unexpected.

What it presents is the property of the particle.

There are still two bars on the screen.

The results of this experiment ......

Once again, all perceptions have been subverted!

And this experiment has also begun to be carried out......

After countless experiments from various angles, a conclusion has been reached that makes everyone's scalp tingle!

On the one hand, no matter when or where the "observer" appears, as long as the observation appears at the moment when the light falls on the screen, the result on the screen must be two bars representing the properties of the particle!

On the other hand, even if the "observer" observes the whole thing, as long as the observation is removed at the last moment before the photon falls on the screen, the result must also represent the grating of wave properties!

To use an analogy......

It's like a movie that's already been made.

If no one watches this movie from beginning to end, it will have an A ending.

But whenever someone watches it, no matter when they start watching it, as long as they see it at the last second, it will present a B ending.

The weird thing is......

Even if you have watched 99.99% of the entire movie, but leave at the last second, its original B ending will immediately perform A ending at this moment!

Even if you enter the set at the last moment, no matter what the movie has played before, the original A ending will change immediately, and the B ending will be directly performed!

But for classical physics, the ending of this movie should not depend on whether or not you have seen this movie!

The sudden appearance of an observer should not change the ending of this movie out of thin air!

According to the law of cause and effect in classical physics......

Cause can determine effect.

But in this experiment......

Whether the observed fruit causes the cause of how the photon passes through the double slit......

That is, the effect determines the cause.

In quantum physics, the "future" ...... It is possible to change "history"!

This kind of anti-common sense conclusion shook the whole world!

And because of this......

Quantum physics and classical physics began to diverge.

Microphysics and macrophysics have not yet been truly unified.

……

These flashed in Lu Yun's mind.

Originally, these memories were fragmentary.

But after going through "parallel memories", he has an almost strange ability for his brain.

He can never forget it.

I don't understand it, but I can really remember it.

Therefore, when Pan Lishan asked this question, Lu Yun immediately turned over this result from his mind.

However, as he began to understand this, he also felt more and more numb in his scalp.

"This ......"

"Why is it kind of like a timeline mission I'm on?"

"The prophecy that was supposed to be the result of all this is the cause of all this?"

"That's ...... for time"

"Is the world macroscopic or microscopic?"

At the same time, he thought of something else.

"In other words, the continental shelf oscillation experiment was carried out on the basis of this characteristic?"

"Microscopic particles must exhibit different states depending on observation......

"And then use the micro to influence the macro?"

Suddenly, Lu Yun was a little stunned.

He suddenly realized what kind of future the successful oscillation experiment of the continental shelf would affect.

Stronger than a nuclear bomb, stronger than a hydrogen bomb, stronger than all the weapons currently possessed by mankind!

“……”

"Causality weapons!?"

It's too complicated.

It's so complicated that it hurts, and "Jindan" seems to be moving again.

Therefore, Lu Yun did not continue to think deeply.

Instead, his eyes fell on Pan Lishan.

At this time, Pan Lishan was meditating.

He wants to use the problem of quantum physics to prove whether Lu Yun comes from the future.

And Lu Yun knew it very well in his heart......

No matter what the next question posed by Pan Lishankou, he could only answer the words "I don't know".

"The Evil God"

Therefore, at the moment when Pan Lishan was about to ask another question, Lu Yun was the first to speak:

"I think you'd better write down the questions you want to ask in a notebook."

"I'll answer them all."

"It's much quicker than asking back and forth."

Lu Yun said this, but he was thinking in his heart......

"It's time."

He raised his wrist and glanced at the time:

"Now it's ......"

"March 1, 1995, 9:28 a.m."

"Everything is ready."

"Operation...... Begin! ”
