Chapter 54 The Observer Effect (Please vote with monthly tickets!)
Just an hour ago, Luo Qing had been having a casual meal with Chairman Sai in New York, having just finished watching a movie. He never expected that he would fly across the Atlantic to Europe in the blink of an eye.

Luo Qing scratched his messy hair; he was also very irritable.

He now has the urge to uproot the entire ETO organization. If he wants to, he can definitely do it; it just takes him a year or two to search for them one by one.

Luo Qing has plenty of ways to open the box.

However, like PDC, he was reluctant to part with the information about the Trisolaran civilization that the ETO organization had revealed, as it was humanity's only source of intelligence.

Unless the Trisolarans abandon ETO, this organization will still have value to human civilization.

After experiencing the ETO's surprise attack on the Great Hadron Collider, Luo Qing realized that the "power" of various countries in the world was all just a facade.

Faced with the Trisolaran rebels empowered by the sophon, the combat power they unleashed far exceeded the expectations of the major powers.

Modern states are an order of magnitude stronger than ancient dynasties, and similarly, the Trisolaran civilization is an order of magnitude stronger than modern states.

Luo Qing is somewhere in the balance between the three.

The NATO forces guarding the Great Hadron Collider are not weak; they are a standard modern armored brigade with a total strength of about 8,000 men, and are the elite of the active-duty armies of various European countries.

This modern armored brigade was actually wiped out by a small arms attack by thousands of Trisolaran rebels, combined with ball lightning formed by dozens of macro-electrons and a few 'rainbow particles'.

This is an asymmetric war.

While the Sophon's long-range communication and unilaterally transparent battlefield information have certainly played a significant role, the most difficult to defend against is the technology provided by the Trisolarans.

Tanks, attack helicopters, armored vehicles, automated counter-attack fire platforms, and drone swarms—these traditional war units are as fragile as paper in the face of Ball Lightning's attack.

Of course, ball lightning is not indefensible. Ball lightning is essentially a macro-electron, and as long as it is an electron, it must carry a charge. As long as it carries a charge, it can be deflected by a magnetic field.

Having learned from this experience, countries should accelerate the deployment of magnetic field deflectors to defend against ball lightning weapons.

But there's no such thing as being able to guard against thieves for a thousand days. Macro-electrons can be defended against with magnetic field reversers, but what about those fingernail-sized 'rainbow particles'? This kind of individual nuclear fission weapon is ultimately unpredictable, and once it explodes, it can cause the power of a hundred-ton TNT explosion. If placed in a crowd, its kill radius is even larger than that of a thermobaric bomb.

The development of technology is a double-edged sword, and Luo Qing finally understood this statement.

...

After declining the invitation from NATO's operational command, Luo Qing wandered through the Jura Mountains, trying to find some useful clues.

For ETO, the operation to seize the hadron collider was a desperate gamble. ETO sacrificed thousands of peripheral warriors to obtain the macro-atoms generated by the collision.

This is all the fault of NATO's joint command for being too slow. From the time the Trisolaran rebels attacked to the time Luo Qing appeared, there was a gap of more than an hour. In the end, it wasn't until the first earth-penetrating nuclear bomb failed to break through the mountain that the NATO commander-in-chief remembered him, the cultivator.

By the time the NATO Supreme Commander contacted the PDC and then, through Sai, contacted himself, the ETO's first round of high-energy particle collision experiments had already concluded.

Even if Luo Qing is fast, it will still take him several minutes to cross the Atlantic.

The other party had clearly taken those existing macro-atomic results in advance.

As for whether the macro-fusion induced by macro-atoms could actually threaten him, Luo Qing couldn't say for sure.

After six years of cultivation on Earth without any spiritual energy, he himself didn't know what kind of immortal he was cultivating, and he wasn't even sure if he could still be considered a Nascent Soul cultivator.

Regarding macro-fusion, it's best to ask Ding Yi for the most reliable advice.

'I'll go talk to Dr. Ding Yi after he comes down from space,' Luo Qing thought to himself, when he suddenly felt a probing gaze.

This feeling is not like that of Tomoko.

Ok?
Luo Qing's divine sense spread out like a tide, and he seemed to touch that familiar figure.

It's that ETO female lieutenant, isn't she dead?

Luo Qing looked up and was astonished to find that the ETO female lieutenant, who had been within the range of his spiritual sense, had vanished in an instant.

"What the hell?"

The spiritual sense scanned the surrounding area inside and out, but still could not find the figure that resembled the female lieutenant from ETO.

The scientific literacy he gained from his predecessor quickly gave Luo Qing an intuitive answer: the quantum ghost.

Luo Qing then thought of the Wallfacer, Frederick Taylor.

About five minutes later.

Luo Qing borrowed an office at the NATO command headquarters and initiated a video call with Ding Yi on the International Space Station.

Although there is some delay in the signal inside the space station, it is not too strong.

In the video, Ding Yi appears to be experimentally activating the space-assembled Large Hadron Collider. He seems somewhat surprised when an astronaut hands him a phone in an insulated bag. However, upon seeing Luo Qing in the video, he immediately understands and quickly puts down his work, flying back to the nearest module.

Luo Qing: "Dr. Ding Yi, I have something to ask you." Ding Yi: "Go ahead."

Luo Qing: "Has quantum mechanics been proven?"

Why are you suddenly asking this? Ding Yi was a little puzzled.

Ding Yi: "Some of them have been confirmed, but there are still contradictions. For example, quantum mechanics and Einstein's general relativity are incompatible, especially when the gravitational field is substituted into the quantum field, such as the problem of black holes and singularities, which will encounter very serious mathematical difficulties [1].

Luo Qing: "I previously reviewed some materials and noticed that string theory is attempting to unify quantum mechanics and general relativity?"

Ding Yi: "That is one of my research directions [2]."

Luo Qing: "So, quantum mechanics has achieved great success in its own field, right... You know Dr. Ding Yi, although I also do physics, I mainly focused on plasma and have been away from the front line of research for many years. I really need your help to answer these questions."

Ding Yi: "It's nothing, it's just quantum mechanics. Why did you suddenly think of this? Did something happen to you?"

Luo Qing told Ding Yi about the attack on the European Hadron Collider by the Trisolaran rebels, the use of a large number of ball lightning weapons on the battlefield, and the ETO female lieutenant.

Ball lightning...

Inside the space capsule, Ding Yi leaned against the observation window, his thoughts drifting uncontrollably to the starry sky. After a while, he finally spoke:
"The ETO lieutenant you saw should be Quantum Ghost, but I have a question: you couldn't possibly see her, so how did you see her?"

Luo Qing: "I only sensed her presence, but I didn't see her."

Ding Yi: "If you don't see anything reasonable, I can tell you the answer."

Luo listened attentively.

Ding Yi: "After the human body resonates with macro-electrons through matter waves, it will also transform every basic particle that makes up the human body into macro-quantum. And you should also know the three major theories of quantum mechanics, namely: uncertainty, quantum superposition, and entanglement."

Ding Yi: "You have already seen quantum entanglement, which is the long-distance communication of sophons, and uncertainty is what you just experienced. That is to say, the ETO female lieutenant who was transformed into macro-quantum was simultaneously in a superposition of two states: being burned or not being burned."

Luo Qing had to admit that Ding Yi's statement was completely counterintuitive.

Even in the world of cultivation, there is no concept of superposition in quantum mechanics. If something exists, it exists; if it doesn't exist, it doesn't exist. Creating something from nothing is your skill, but creating nothing from something is like being robbed. What does it matter whether something exists or not?
Luo Qing: "Schrödinger's unlucky cat, huh?"

Ding Yi: "It's even more supernatural than that. That female lieutenant from ETO, although she was in a superposition of being burned or not burned, your observation directly caused her quantum state to collapse into the burned state."

Luo Qing: "My observation?"

Ding Yi: "Yes, the quantum wave function collapsed the moment you observed it. I know you have many special detection methods, but it's the same for quantum mechanics. From the moment you started paying attention, the result changed."

Luo Qing said, "I have a spiritual consciousness."

Ding Yi paused, then shook his head: "Whether it's spiritual sense, vision, a camera, or the observation of a sophon, they all belong to strong observation. Let alone conscious observation, even just placing a stone or a grain of sand is considered weak observation, and it still has the probability of causing quantum state collapse. This is the observer effect."

Luo Qing remained silent after hearing this.

Quantum mechanics, when applied to the world of cultivation, can easily lead to inner demons.

Their cultivation world is very materialistic; all cultivation methods are traceable, and cultivation is a gradual process of climbing step by step.

But quantum mechanics is purely God (crossed out) the way of heaven rolling dice.

Luo Qing said, "In this small-scale war, there may have been thousands of soldiers who died from ball lightning."

Ding Yi no longer leaned against the cabin wall. In the microgravity space capsule, he struggled to turn himself upside down and pressed himself against the observation window.

Ding Yi said, "Then there would be thousands of quantum ghosts. In essence, the energy release of ball lightning is the overlap or partial overlap with the two probability clouds of the target. Taylor's quantum fleet makes sense. It can only be said that he overlooked one thing."

Luo Qing: "What is it?"

Ding Yi: "That is the existence of quantum state, which makes it almost impossible to interfere with the existence of real matter. This is also why the Trisolarans are completely indifferent to the so-called quantum fleet."

Ding Yi: "Go and look for them. There should be other quantum ghosts. It's best to go at night."

Luo Qing: "Can I see them?"

Ding Yi waved his hand heavily, as if to chase away Luo Qing's thoughts: "Never! Absolutely impossible... Of course, you are different. If you can see him, then you must come to me. I also have someone I want to see."

[1]: Quantum mechanics describes the behavior of particles in the microscopic world, possessing characteristics such as uncertainty, quantum superposition, and entanglement. Its basic framework is based on quantum states and operators. General relativity, on the other hand, is a theory about gravity, which describes gravity as the curvature of spacetime, based on the concept of a smooth spacetime manifold. These two theories have very different ways of describing the physical world and their conceptual foundations.

The combined result of these two calculations often leads to infinity, hence Ding Yi's statement in the text that it would cause 'serious mathematical difficulties'.

[2]: String theory posits that the fundamental units of nature are not point particles, but one-dimensional "strings." These strings can be open strings (with two endpoints/line segments) or closed strings (forming a closed loop/ring). Different vibrational modes of the strings correspond to different fundamental particles, such as electrons, quarks, and photons. String theory attempts to unify gravity, electromagnetism, the weak interaction, and the strong interaction within a single theoretical framework, resolving the incompatibility between quantum mechanics and general relativity.

In Liu Cixin's novel *Collapse*, Ding Yi achieved a unification of the four fundamental forces. Therefore, in this paper, Ding Yi believes that string theory holds the promise of unifying the four fundamental forces. However, the Ding Yi in this paper has not yet completed the construction of a grand unified field theory; he will be given several hundred chapters to develop.
