"Don't forget..."

"I'm from 2023."

These words were like a heavy hammer that suddenly hit Pan Lishan's heart.

He looked at Lu Yun in astonishment, his eyes narrowed, looking extremely unbelievable.

But while he couldn't believe it, he was somewhat willing to believe it...

This is not a contradiction.

Especially when it comes to a young quantum mechanics scholar, it seems even more natural.

Time travel has great temptation for Pan Lishan.

But he still held a cautious attitude.

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

He didn't know what kind of attitude he should show in order to let the other party understand his inner state.

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

He knew very well Pan Lishan's mental state at this moment.

Taking advantage of his hesitation, Lu Yun continued to speak:

"Since I come from 2023, I naturally have a mission on my shoulders."

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

"I think……"

"You should be able to understand this."

These rhetorics that ensure the stability of space and time...

Of course Lu Yun made it up.

But the effect is outstanding.

Because as soon as Lu Yun said these words, Pan Lishan visibly swallowed and his lips turned white.

Pan Lishan understood these words as he should. His heartbeat was accelerating and he was extremely shocked.

He carefully eliminated all external factors and immediately thought of the most important part of Lu Yun's words:

"Is he a person sent by the country in 2023?"

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

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

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

The feeling of being so trusted and valued is truly wonderful.

However, he still maintained the most basic vigilance.

He knew that he couldn't just believe it because the other party didn't provide any substantive evidence.

He frowned, and then asked cautiously:

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

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

"I said I was asked not to reveal too much information."

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

"I know it's hard for you to believe."

"That's why I came to 1995."

"This is part of my mission."

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

Of course he can understand that the premature emergence of future items will make the future full of uncertainty.

So, he lowered his head and began to think deeply.

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

Soon, he raised his head and asked:

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

He looked at Lu Yun with bright eyes, filled with great expectation!

The quantum physics that I study is the most cutting-edge in the world and even all mankind. In recent years, experiments on quantum physics are gradually breaking through the original imagination!

If the other party really comes from 2023...

If the other party really comes here for experimental cooperation...

Then this question should be easy to answer!

However, when this question was asked, Lu Yun felt relieved.

happen……

He knew the answer to this question.

Pan Lishan never dreamed of...

The questions he asked have been ruined by marketing accounts.

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... on whether it's observed or not."

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

However, this question is just a starting point. He plans to continue asking. The difficulty of the questions will of course gradually increase to verify whether he comes from the future.

So, he lowered his head and fell silent, and began to think about the questions he wanted to ask next.

But Lu Yun took a deep breath quietly.

At this moment, everything related to the double-slit interference experiment flashed through his mind.

…

The experiment simply goes like this...

In the 19th century, due to the debate over whether light is a wave or a particle, the double-slit interference experiment was started.

The result was an earthquake-like violent tremor in the physics community at that time!

Whether light will appear in a particle state or a wave state depends on observation!

Observations will produce different results!

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

If photons are observed, the light will take on the state of particles.

Observation and non-observation actually present two completely different answers!

Later, Einstein used "wave-particle duality" to explain this result. This was also a characteristic mentioned in the high school textbook, which led to the equation E=hv.

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

Move the "observer" that observes photons from in front of the double slit to in front of the screen of the final result.

Logically speaking, if there is no observer to observe the light before it passes through the double slits, then it should exhibit the properties of a wave.

But the conclusion was completely unexpected.

What it presents are the properties of particles.

There are still two bars on the screen.

The results of this experiment...

Subverted all perceptions again!

And this experiment has begun to continue...

After countless experiments from various angles, we came to a conclusion that made everyone’s scalp numb!

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

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

To use an analogy...

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

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