215: Chapter 215: Professor, spacetime, gravity, and quantum entanglement don't exist, understand?

"Then, Student Jiang Zhe, please listen to the question!"

"Many people know that Quantum Mechanics and the Theory of Relativity are the two pillars of modern physics."

"The former rules the world of microscopic particles, telling us that the essence of all things is a Probability Wave, but can also be a particle."

"The latter describes the macroscopic universe, stating that matter causes spacetime to curve, generating gravity."

"But the problem is!" The professor grinned. "These two most successful theories are incompatible with each other!"

"Using the equations of General Relativity to calculate the center of a black hole yields a Singularity with infinite density, which is clearly absurd!"

"Using Quantum Mechanics to describe the birth of the entire universe also results in stumbling calculations."

"Physicists have searched for decades but cannot find an ultimate theory that perfectly unifies the two!"

Having said this, the physics professor nodded slightly. "So, the question I have chosen is—"

"In an ultimate theory that is more fundamental and yet to be found, which is more fundamental: the spacetime we are familiar with—time and space—or the mysterious [Quantum Entanglement] in Quantum Mechanics?"

"Is there a deep connection between them that we have yet to understand?"

"Recently, a so-called [Time Stream] appeared on the internet that can indeed explain Quantum Entanglement, but that is not quite enough!"

"Now, please share your thoughts!"

What the professor was asking was which one is more important; or rather, why in the same world, the macro and micro are logically inconsistent with each other!

Could the macroscopic bible, the Theory of Relativity, and the microscopic bible, Quantum Mechanics, be perfectly combined!

Who would have thought that as soon as the question was asked, it would cause countless netizens to frown.

"??? What's going on?"

"This question sounds so high-level. Is this something I can listen to for free?"

"Professor, did you walk onto the wrong set? This is an entrance test, not a Nobel Prize defense, hey!"

"Brother is in danger; this question is clearly way beyond the scope, out into outer space!"

"And that professor doesn't seem to recognize the [Time Stream] much; otherwise, he wouldn't fail to recognize Brother!!"

"..."

Huaqing University dormitory building.

When Professor Wu heard the question, he frowned deeply. "What is going on? Using this question to test a young man participating in an entrance test... this is clearly a topic at the level of a modern theoretical physics seminar."

Ouyang Baili narrowed his eyes. "No, every physics student will eventually face this question. It's better to let it be exposed early. This physics professor didn't ask for an answer, but rather for Jiang Zhe to talk about the issue."

"The Time Stream Jiang Zhe proposed before might have some truths behind it regarding the combination of the macro and micro. I want to hear it; I want to hear what he will actually say."

Inside the Principal's office.

Old Yu the Physicist's fists clenched. "Is this a topic that can be used for an exam? This old fellow is clearly making things difficult. If you asked me to answer, even I couldn't do it. Even if you brought in the world's top theoretical physicists, they wouldn't adjourn the meeting without discussing it for ten days or half a month!!!"

Principal Fu, Old Wang, and Xiao Wang looked at each other. Although they didn't quite understand the specifics, seeing Old Yu's reaction and momentum, they felt an extraordinary pressure. The three of them couldn't help but break into a cold sweat for Jiang Zhe!

In the living room.

Xiao Yu sat on the single sofa behind Jiang Zhe with her legs crossed.

Although she didn't understand some of the technical terms, she felt the professor opposite was making a mountain out of a molehill—was such a simple question worth being so serious?

Jiang Zhe, however, didn't show any expression of surprise.

A few seconds later, the corner of his mouth curled slightly. Perhaps others couldn't give an answer, but his previous life had relevant hypotheses to prove that the macro and micro could be merged into one.

Finally, he spoke unhurriedly:

"Professor, the question you raised is excellent; it points directly to the deepest crack in the foundation of the modern physics building!"

"Many people have tried to build a bridge over this crack, attempting to glue Quantum Mechanics and General Relativity together."

"But perhaps, we have been heading in the wrong direction from the start."

"Scientists shouldn't ask how the stage of spacetime accommodates the actors of quantum phenomena."

"Instead, they should ask: [Could the stage of spacetime itself be woven from more fundamental quantum phenomena?]"

At this point, he turned back to look at Xiao Yu, who was scrolling through her phone. "Xiao Yu, do you remember the analogy I made about the universe when I was tutoring you? What did I say the universe was like?"

Xiao Yu was busy typing and chatting with netizens. When she was called, she blanked for a moment. "Ah? Oh, I think you said the universe is like a very, very large movie screen—it has almost no measurable curvature, but it looks like a circle, and it also seems three-dimensional..."

"I also remember Brother saying that the little people on a phone screen can never jump out of the screen, as if all the Big Bangs and such are just displayed on the phone screen."

Having said this, she frowned. "I don't remember very clearly!"

Jiang Zhe nodded gently, not making things difficult for Xiao Yu anymore. Looking at the desk, he casually picked up a clean sheet of A4 paper and drew a few stick figures on it with a signature pen.

"Professor, assume this piece of paper is a two-dimensional, completely flat world."

"The little people living on this piece of paper only have front, back, left, and right; they cannot understand [up and down]."

Then, Jiang Zhe lightly pushed up the paper with his finger, creating a curve in a section of it. "Now look, for the little people on the paper—a [curvature] has suddenly appeared here!"

"They might think: [Wow! There's a mysterious force here making our straight path curve!]"

"So, the stick figures living on this paper would invent a complex set of theories to describe this [curving force]."

"But for those of us living in the real world, namely three-dimensional spacetime..." He smiled slightly. "We can see through it at a glance—there is no mysterious force (gravity) at all; it's simply the paper itself [bending] in a higher dimension."

"The so-called [force] is just a sensation low-dimensional beings have towards high-dimensional geometric changes, a [translation] of a phenomenon!"

As the string of words fell, the reactions of the netizens and the professor were completely different.

The netizens were full of question marks.

"What's going on?"

"Brother, what are you doing? This is so simple and easy to understand; are you afraid the professor won't understand?"

"Upstairs, stop talking nonsense. Don't you see Brother is giving a lecture to the professor like he's an elementary school student? If he doesn't make it simple and easy to understand, how would the professor understand?"

"This... I am actually speechless!"

In the video, the nearly sixty-year-old physics professor was stunned.

This simple and easy-to-understand opening and analogy were completely different from the serious derivations he had imagined, yet they were very clear and comprehensible.

Why do I have a feeling that you are treating me like an elementary school student???

He didn't know if it was an illusion!

Jiang Zhe's explanation continued slowly: "So, back to your question. Is it possible that the spacetime and gravity that scientists are painstakingly pursuing are just like the [curving force] felt by the little people on the paper?"

"They might not be the most fundamental things, but rather phenomena or side effects presented by something more underlying and fundamental."

At this point, he paused for 2.5 seconds and continued his simple explanation:

"Let's use another analogy!"

"You must have played 3D games, surely some open-world masterpieces."

The professor nodded subconsciously; playing games these days wasn't exclusive to young people.

"Good, very good. In your game, there are majestic mountains and deep canyons. Characters can run and jump, objects collide, and the game world has gravity effects after falling and getting injured. Everything is so real, right?"

The professor nodded.

"But!"

As Jiang Zhe changed his tone, "In essence, all the 3D worlds you see and feel, including the physical laws within them like gravity, are just your computer's graphics card rendering and calculating images and effects in real-time based on lines of code in the game program and 2D texture data stored on the hard drive!!!"

"Code and data are the foundation of a game world; they are the cause of a game world."

"Of course, I'm not talking about a real game world, but... our world!"

"Whether it's the 3D game world you see and feel now or our real world, the physical laws within them are the results brought by code, the visual presentation brought by underlying calculations."

And this analogy was even more shocking than the paper world just now because it was so close to modern life!!!

As the string of words fell, the netizens all felt their scalps tingle.

If someone else had said this, they would have said the person was crazy; but the key was that it was Brother!

"Holy crap, I understand this!"

"Damn, Brother turned such a difficult matter into something simple and easy to understand. What kind of level does this even require?"

"Information is the code, and spacetime is the result rendered by the real world?"

"My scalp is tingling!!!"

"..."

In the video, the elegant physics professor's glasses almost fell off in shock.

He stared fixedly at Jiang Zhe, his mouth slightly open.

He felt that this Student J was being very considerate of him, fearing he wouldn't understand, which is why he deliberately made it so simple?

Before the professor could react, Jiang Zhe gave an incredibly simple answer.

"So, Professor, this hypothesis of mine is called the Holographic Universe Theory, and its answer is also very simple!"

"Whether it's microscopic Quantum Entanglement or whatever macroscopic physical changes, they are likely the underlying code and data that construct our universe."

"And the time, space, matter, and gravity we humans perceive, including those grand relativity equations you study, might just be the [special effects] and [interactive experience] rendered on the [perception interface] or [screen] of our life form when this underlying code is running."

"Just like the [scenery] and [physics engine] in a game, they don't come out of thin air; they are generated by code."

"Everything in our universe might just be something generated after the universe's source code runs."

"Looking for contradictions between those two theories is like arguing over whether the [fire effect] or the [ice effect] in a game is more fundamental. Perhaps you should directly study the programming language used to write the game—that is, the laws of quantum information—rather than splitting hairs over the Theory of Relativity and Quantum Mechanics."

As the final few instructional words fell, the netizens in the livestream room, Principal Fu, Ouyang Baili, Old Yu the Physicist, and the others all fell into a daze.

Turning a super difficult major event into plain language that even an elementary school student could understand.

What on earth is this Jiang Zhe doing?

Is he really still just a 25-year-old young man?

The professor on the screen was full of astonishment. He had originally wanted to test this very clever but somewhat proud young man.

Who would have thought that the simple analogy the young man spoke would leave him unable to open his mouth to refute.

Because he knew—only the truth is irrefutable and leaves one without even the desire to argue!

At this moment, the fragmented complex theories and the incessantly arguing schools of thought in his mind were washed clean by these two small analogies, yet they vaguely pointed towards an incredible possibility!!!

Jiang Zhe looked at the professor, who had been unable to speak for a long time, waited for over twenty seconds, and then asked softly:

"Professor, you should understand this answer clearly by now, right?"

"If you think it's too simple, I also have a slightly more complex version that uses some mathematical language and physics equations. Do you think you need to hear it?"
