Those who face the wall, but are in the Nascent Soul stage.

Chapter 379 I chose the fourth option (3k)

Clearly, no one present believed that Ding Yi's true love was a female human.

Luo Ji said helplessly, "You may have said yourself that those standard cosmological models are correct. If so many standard cosmological models still can't satisfy you, then what should your true love be like?"

Ding Yi didn't speak, but looked at Luo Qing with longing in his eyes.

Luo Qing opened his eyes again, speaking sparingly: "Don't do anything."

He then managed to squeeze out a few more words: "I cultivate the Path of Ruthlessness... or at least I have cultivated the Path of Ruthlessness."

The originally serious atmosphere was turned into amusement by Luo Qing's bizarre answer.

Tu Hengyu suppressed a laugh and said, "So Dr. Einstein, you still haven't explained why you stopped Dr. Ding Yi from speaking just now."

Einstein gave the young man a frank smile: "I have already told you about the observer effect in quantum mechanics."

Tu Hengyu vaguely realized something.

Luo Qing's divided soul sighed softly.

Ding Yi closed his eyes and remained silent.

Luo Ji reacted much faster than Tu Hengyu. He was somewhat puzzled: "Judging from your tone, this observer should be omnipresent. Faced with such an observer, can we just not speak or express anything? Won't it directly read our thoughts?"

This time, without Einstein's answer, Ding Yi answered Luo Ji's question:

"Human brain activity also possesses the uncertainty of quantum mechanics, meaning that the generation of human thoughts is probabilistic. For example, I was just wondering if anyone was still selling egg pancakes at the entrance of Wangfujing. Who could have predicted that someone like me, whose mind is full of physics, would start thinking about egg pancakes? So, if you only think about it and don't say it, you'll probably be fine."

Thought possesses quantum uncertainty, a universally acknowledged truth in the universe.

This is also one of the underlying logics of the Dark Forest Theory: if you can read someone's thoughts, then there is no chain of suspicion. It is precisely because you cannot read someone's thoughts that the chain of suspicion exists, and the Dark Forest based on the chain of suspicion exists.

Luo Ji immediately understood, but then he suddenly realized something and shuddered: "Old Ding, you remind me of the painful times when I was a Wallfacer, so it's not Zhi Zi monitoring us now, it's someone else, right?"

Ding Yi glanced at him: "Only now do you realize? From the moment you became a cultivator like Luo Qing, your mission as a Wallfacer most likely never ended, and may even have been extended indefinitely."

Upon hearing this, Luo Ji clutched his head and cried out, "Oh God, just kill me!"

Luo Qing, who was in the corner, suddenly produced a spirit sword from his fingertips.

Luo Ji raised both hands: "Brother Qing, I was just joking."

Luo Qing tossed the spirit sword into Luo Ji's arms: "The Canghai Sword is a high-grade spiritual weapon. It is very compatible with your cultivation method. However, with your cultivation level, you probably cannot unleash its full power yet. You will have to wait until the late Golden Core stage. I'm giving it to you for future life-saving purposes."

Luo Ji's cultivation technique is the Canghai Juyuan Jue, a superior technique with the characteristic of continuous life that Luo Qing found in his own cultivation technique library. He modified it into a special technique that allows for self-cultivation and improvement, and enables cultivation in a spiritless world.

Luo Ji held the spirit sword named Canghai Sword, staring wide-eyed at the sword spirit inside.

"This……"

This was the first time Luo Ji had encountered such a spiritual object. He hurriedly placed it on the table, but unexpectedly, the spirit sword disappeared the moment it left his hand.

"what's the situation?"

Luo Qing explained helplessly, "All the magical artifacts in my possession suffered the macro-fusion attack along with me and have quantum effects. Once they are observed by an observer, they will collapse into a state of destruction. If you want to use them, you have to refine them and make them resonate with your mind. Only in this way can you suppress the observer effect and prevent them from collapsing into a state of destruction at any time."

After saying that, Luo Qing's divided soul retrieved the sword from the quantum world and handed it back to him, saying, "Don't let it go before you refine it, otherwise it will collapse into a state of destruction at any time, and then you won't be able to find it."

Luo Ji held the spirit sword in his arms.

The matter of Luo Qing gifting the sword was just a minor episode.

But Luo Qing's words made everyone realize that the Nascent Soul cultivator in front of them was essentially a quantum ghost.

After listening to the physics experts chat for half a day, Tu Hengyu finally caught up with the conversation and asked Luo Qing a question.

"Professor Luo Qing, why aren't you suppressed into a destructive state by the observer effect?"

Luo Qing explained, "That's because your observer effect isn't strong enough. My own observer effect can offset the external observer effect, using the internal to counteract the external."

Currently, the combined observer effect of the human world, the Trisolaran world, and the Devouring Empire is far less than my internal observer effect. Therefore, I can ignore you and appear within this macroscopic world.

Ding Yi said quietly, "In other words, if all the observers in the universe were looking at you, you might very well collapse back into a quantum state?"

Luo Qing hesitated for a moment, but finally nodded.

The scene of being glanced at by that absolutely rigid body through the light cone telescope, and immediately collapsing into a quantum destruction state, was still vivid in his mind.

The mysterious observer from beyond the sky, which also caused him to collapse countless times in a short period of time, are the main reasons why Luo Qing dares not act rashly at this moment.

My own strength is weak, and it is far less effective to expand from the Nascent Soul stage than from the Mahayana stage. Moreover, the power of the will of all beings is my last trump card, so I dare not overstep it in the slightest.

The event of witnessing the destruction of the solar system fleet while trapped in the sub-light speed realm left a deep inner demon on this cultivator who was only interested in stability.

To play it safe or to act recklessly? He has already tried both in his past and present lives, and paid a price he could not bear. This choice is still a problem for him.

Ding Yi stood up, and an inexplicable aura erupted from him.
At that moment, his aura overwhelmed the most knowledgeable little moss, the only Foundation Establishment cultivator present, the only Nascent Soul cultivator, and even Einstein and Tu Hengyu. "I got some answers from Yang Dong."

Ding Yi's words immediately attracted everyone's attention.

Luo Qing raised an eyebrow: "You also know the art of refining souls?"

Ding Yi glared at Luo Qing.

Luo Ji smoothed things over: "Old Qing, this is not the time for jokes. Ding Yi, you tell me, actually I've never understood why Yang Dong couldn't think straight. Although Teacher Ye is his mother, I don't think that reason alone would be enough for Yang Dong to commit suicide."

As for Sophon's miraculous project... Sophon's miracles might fool a fool like Wang Miao, but since Yang Dong knows about the Three-Body Problem, he must know about Sophon, and it's even less likely he would be tricked into committing suicide by Sophon.

In fact, Luo Ji had always been puzzled by Yang Dong's death, as he remembered her as a rather sunny and cheerful girl.

Ding Yi calmly said, "I guessed the reason for Yang Dong's death a long time ago. It's nothing more than that the universe is no longer pure. The war between advanced civilizations has made the universe's structure riddled with holes. Both the Risk Eliminators and the Carbon-Based Federation have mentioned this. Yang Dong saw this many years before me, which is why she chose to commit suicide. She essentially saw through the future of the universe at a glance."

Everyone nodded.

The future of the universe is a pessimistic ending. After so many things like the Carbon-based Federation and the Altar of Truth, many human scientists have realized this, but they haven't taken it to heart. Such things are still too far removed from human civilization.

Before the assembled audience, Ding Yi began his final discourse. He no longer cared about the unknown observer; he wasn't a Wallfacer, so why should he think so much?
"The standard model of the universe provided by the risk avoiders is not the problem; the problem lies with our universe."

Ding Yi set the tone first:
"To put it bluntly, the universe itself has design flaws in its structure. The most direct evidence is the non-conservation of parity, the indirect evidence is the observer effect, and the concrete evidence is the finite speed of light."

First, the speed of light is finite. According to string theory... First of all, I don't know whether string theory is right or wrong. I'll assume it's right for now. According to string theory, the speed of light in a vacuum should change dynamically with energy density.

The pattern of light speed increasing due to higher energy density in higher-dimensional space and decreasing due to lower energy density in lower-dimensional space is correct. However, the measured values ​​should not be constant multiples of the speed of light in the three-dimensional universe; they should be dynamic.

My hypothesis is that when a particle attempts to exceed the speed of light, the quantum fluctuations of the foam convert its kinetic energy into the mass of virtual particle pairs, forcibly suppressing its speed. This could explain the finite speed of light. But the question remains: what is suppressing the speed of light?

Everyone looked at each other.

Who is suppressing the speed of light?
"Could it be that a god-level civilization has altered the fixed value of the speed of light?" Tu Hengyu said.

Luo Qing shook his head upon hearing this: "Li Bai's clan is a top-level god-like civilization in the universe. They can enter eleven-dimensional space and move at a terrifying speed of 0.162 meters per Planck time. Even if they reach the end of the universe, it will only be an instant. However, this speed does not conform to Dr. Ding Yi's hypothesis. Moreover, I asked Li Bai, and he naturally believes that the speed of light is fixed."

"second."

Ding Yi raised his second finger.

"Parity is not conserved, there's not much to say about that, it's just a matter of inflow and outflow. Moreover, I suspect that this asymmetry is slowly spreading, and it's very likely that every billion years, the parity violation rate in weak interactions will increase by one part in ten thousand. Of course, the specific data is impossible for humans to calculate, and even the carbon-based federation is unlikely to be able to calculate it."

If this parity non-conservation were allowed to continue unchecked, it would lead to a very serious consequence: decreased nuclear stability and a sharp drop in stellar nuclear fusion efficiency, directly suggesting that the universe is undergoing a degradation process beyond mere entropy increase.

The crowd fell silent, gazing at Ding Yi with awe.

"third."

Ding Yi raised his third finger.

"When I tried to describe quantum phenomena using the standard cosmological model, I encountered an irreconcilable contradiction. Normally, quantum phenomena should be included within the standard cosmological model, but the model proposed by the risk-mitigator cannot do so."

Either the model is wrong, or the universe is wrong, or quantum mechanics is wrong.

I tend to think that all three have some issues.
When I used the Grand Unified Theorem to simulate the quantum tunneling probability of macroscopic objects, I found discrepancies between theoretical and experimental values. For example, using a quantum computer, I calculated the probability that Earth would tunnel into Proxima Centauri's orbit in the next 10^100 years, but the probability predicted by the formula was far greater than that, and the data varied with each simulation. I suspect that there are special observers in the universe who, when I attempt precise calculations, automatically adjust the arrangement of spacetime pixels, deliberately creating unavoidable errors.

After Ding Yi finished speaking, he added further evidence:
"Of course, it's also possible that quantum computers are still too outdated, and I might need a superstring computer."

The little moss, who was inexplicably criticized, snorted in dissatisfaction.

Everyone continued to look at Ding Yi, seemingly anticipating his final conclusion.

Ding Yi added, “I discovered that these three contradictions point to the same root cause—the mathematical self-consistency of the universe is contradictory. But if I remember correctly, someone once asked the risk-resolver a question: ‘Is mathematics self-consistent?’ And the risk-resolver’s answer was ‘Yes.’ This is another contradiction.”

A faint round of applause came from Einstein.

Finally, amidst this solitary applause, Ding Yi casually uttered his last words:

"Or, the universe is a failed experiment by some higher civilization."

"Or, the universe is a bad die that God rolled."

"Or, the universe is a faulty system that is heading towards a crash."

"Everyone, here are three options. Choose one."

After listening, Luo Ji's lips moved, but he only uttered one word:

"Hold"

"Turn this universe upside down."

Luo Qing spoke up, adding a fourth option for Luo Ji.
