"Do you know that when you stop observing the world, does the world disappear, or do you disappear?"
"Is there a difference?"
The abruptly emerging information from the system left Song Han a bit confused.
"These two viewpoints respectively represent two dividing points in the cognition of the world, absolute materialism and absolute idealism. One only believes in the world that exists in front of one's eyes, and the other believes that the world exists only because it is seen by the 'ego'."
Song Han asked in confusion, "What does this have to do with our trip to Country C this time?"
"In quantum mechanics, according to the Copenhagen interpretation, when a quantum system is not measured, its state is a superposition of various possibilities , and measurement will cause the wave function to collapse into a definite state. They regard this as the truth without thinking about the meaning of observation itself. The consciousness theory of John von Neumann holds that it is human consciousness that causes the measurement collapse. Human consciousness comes from neurons, and the electrical signals of neurons themselves are composed of microscopic quanta. The process of consciousness absorbing external information is the process of entanglement collapse. When the wave function collapses, the original information of the wave function is transferred into human consciousness, which is the essential reason for the collapse of the wave function. In order to attack this idealist theory, the Copenhagen School chose a pig as the observer in the quantum experiment, and the result was that the pig's observation could not cause the wave function to collapse. Do you know what this means?"
Song Han stared blankly at the information fed back by the system on his retina. "What does it mean?"
"It means that the moon exists because of the gaze of that curious human on Earth, not a mouse."
Song Han didn't have much of a psychological change regarding the information replied by the system. This made the system waste a classic century-old quantum mechanics meme in vain.
The system helplessly continued to explain, "The enemy we are facing doesn't have a real physical structure, but as long as it exists in this universe, it must follow the basic principles of the universe. When it travels back and forth in the space-time scale to search for us, the state it presents is a wave function with countless possible superpositions. However, when it observes us, we also observe it. Before eliminating us as observers, it will also inevitably exist in this world with a real physical structure."
Song Han painfully pulled his hair, resenting his meager knowledge of quantum mechanics. If he had known that the knowledge of quantum mechanics would be closely related to his future, he would definitely have used it as a pillow even when sleeping. Even if he didn't have time to read it, he would have engraved that knowledge firmly in his head.
The intense thinking activity in Song Han's brain also satisfied the system quite a bit. The host's subjective initiative still needs to be continuously stimulated and mobilized to be truly inspired. The host has been too decadent in the past three months, and the system has taken care of everything. It always feels that if this continues, the host will be turned into a useless person.
"So, what exactly are we dealing with now?"
"It could be a person, it could be a dog, or it could be a complex electromagnetic wave, a continuous biological wave. We need to observe in detail what kind of macroscopic material basis the other side will present when we get close to it."
Upon seeing the system's information, Song Han immediately jumped up. "Are you crazy! We can't even hide from it in time, and you want us to look for it?"
"Sir, are you okay?"
At an altitude of tens of thousands of meters, Song Han's sudden movement attracted the attention of the passengers on the plane. Seeing the gaze from the flight attendant, Song Han forced a smile, quickly apologized, and then sat back down.
Looking at the message replied by the system in his eyes, Song Han suppressed the panic in his heart and asked, "What if the other side controls a group of people again? Are we going to start killing? At that time, we will become the world's number one wanted criminals!"
The system didn't directly answer Song Han's question but instead retorted, "Do you know what the simplest way to destroy us is?"
"What?"
"A war that extinguishes human civilization."
The system said coldly, "If you don't want this tragic reality to become the future of humanity, you must find it! Compared to finding us among the seven billion people around the world, starting a war that extinguishes humanity is actually easier for an existence like it. It can't exist in our current space-time forever. Compared with our eagerness to understand the other side, it attaches even more importance to whether we exist or not."
The system's words seemed to make Song Han see the rumble of a nuclear explosion shining before his eyes. "Even if there is a global nuclear war, it may not necessarily kill us. Why do we have to step forward?"
"All our actions are just a possibility in space-time before they become the past. As long as a war within the world can make the wave function collapse towards the result expected by the other side, it will not hesitate to do it."
Song Han was powerless to refute the system's words, but he always felt that something was wrong. "The microscopic quantum world forms the macroscopic world and no longer follows the principle of quantum uncertainty. There is an insurmountable boundary between classical mechanics and quantum mechanics. Isn't this the existing consensus?"
The system said calmly, "When we appeared here across space-time, the boundary between them disappeared. Our very existence represents the integration of classical mechanics and quantum mechanics."
Song Han slumped in his seat weakly. He turned his head to look at the people with different expressions in the cabin and asked in a low voice, "So, are we going to save the world now?"
The system said indifferently, "We're just going to intervene through observation and collapse a pessimistic possibility in the development of human civilization into an optimistic reality that meets human expectations."
"Are you sure this excavation won't cause a collapse?"
At the top of Hengduan Mountain in Mountain City, on the hillside where the underground facilities of the Future Science and Technology Museum are located.
The engineer beside him flipped through the structural diagram in his hand, which was older than him, pushed his glasses, and said seriously, "According to the engineering standards on the structural diagram, as long as we don't carry out large-scale blasting operations, it won't have a structural impact on the underground facilities. After all, the construction standard here was originally designed to withstand a nuclear war."
The engineer's reply made Wang Wei's expression change. He asked, "If a nuclear bomb is detonated inside, can the underground engineering facilities withstand the impact of the nuclear explosion without affecting the outside world?"
Wang Wei's question made the engineer stunned for a moment. He turned his head to look at the fully armed soldiers around him, thought for a while, and said in a rather ambiguous tone, "Theoretically, since it can withstand the nuclear impact from the outside, it should also be able to withstand the impact from the inside. However, in a sealed environment, the impact of the nuclear explosion will be magnified. Specifically, it still needs to be calculated according to the yield of this nuclear bomb."
Wang Wei understood. It was a statement that was not exactly nonsense.
"Use a helicopter to transfer a few more excavators here. I need to see the passage in 12 hours!"
After giving the order, in a short while, the rumbling of machinery resounded through the mountain forest.
Looking at the construction site in front of him and knowing that there would be no result for a while, Wang Wei turned around and led the people back to the temporary command center in front of the gate of the science and technology museum at the foot of the mountain.
Not long after arriving at the station, the news from Liu Xi made Wang Wei helplessly set out again.
One large loaded fleet after another kept operating in the residential areas on the outskirts of Mountain City. The people who still remembered the earthquake that occurred three months ago had no doubts. They followed the arrangements and guidance and headed towards the resettlement sites, a huge and sturdy underground war defense facility that was temporarily activated.
"Do you know that within a hundred miles of the science and technology museum near Mountain City, the transfer and resettlement of 360,000 people were involved. In order to complete the task safely, the troops that had just been withdrawn from the earthquake area started to execute a new maintenance and blockade task without taking a rest."
Wang Wei pointed at the tired but firmly standing figures outside and the passing buses and raised his voice. "They privately refined radioactive elements and privately manufactured nuclear industrial facilities. After preliminary investigation, the radiation concentration in the current science and technology museum underground is 300 times that of the outside world, and there has been a leakage! Are you sure you don't want to tell us something?"
Luo Xiang, who had traveled thousands of miles without stopping and still hadn't figured out the situation, stared blankly at the people being transferred outside and also blankly listened to Wang Wei's question. "What do you want me to say?"
Upon hearing this, Wang Wei turned his head to look at Liu Xi, who also looked tired. "Didn't you ask?"
"Didn't you say to be polite?"
Wang Wei didn't dwell on this small information communication error. He stared fixedly into Luo Xiang's eyes and asked word by word, "Who is your boss! Where is he!"
"I don't know..."
"You don't know!!?"
Wang Wei angrily said, "Hundreds of billions of assets, with hundreds of millions of dollars in cash flowing every day. In the company's senior management structure, besides you, there are only a group of lawyers and accountants, and they're all your classmates! Factionalism is not enough to describe the nepotism in your company! Why does he trust you so much and entrust you with handling such a large amount of assets! Is it because you're fat and bald?"
Luo Xiang adjusted his frameless glasses on the bridge of his nose and said proudly, "It may also be because of my education and my awe of the law and inner morality. Sometimes, I'm quite surprised that I haven't been tempted by these assets."
Seeing the increasingly dangerous light in Wang Wei's eyes, Luo Xiang forced a smile. "How about you return my phone to me, and I'll help you ask?"
