Reborn in 2010, the AI ​​in my mind is too powerful.

Professor Xenius carefully assessed his own strength; due to the effects of cancer, his physical condition wasn't good. Even though Chen Yiran seemed a bit dazed, he felt he might not be able to win.

Besides, this island belongs to someone else. Even if he broke out, it would be impossible for him to escape by boat. Although it's not exactly a case of everyone being a soldier, on average, every family here has someone working in the security department. Moreover, the island is covered with cameras, drones, and robotic dogs everywhere. There are even various trained police dogs patrolling around.

Professor Xenius convinced himself that even if the future world was indeed ruled, he wouldn't be considered an accomplice; at most, he would be considered coerced.

Once he abandoned the idea of ​​running away, Professor Xenoy's curiosity immediately took over.

"Don't worry, I'll stay here for the rest of my life! Later, I'll bring my children and everything over here. Don't worry, I'll just call them and say I'm seriously ill to trick them into coming. My son and daughter are both very filial."

So can you tell me what exactly happened? Why are there two waveforms in your brain? That doesn't make sense!

"First of all, I don't fully understand it myself; I need to learn more. Secondly, even if I do fully understand it, I might not tell you."

"Boss, I don't have many years left to live. You must do your best to figure this out. Tell me when I'm on my deathbed, okay?"

"Okay, let's go out. Let's not keep the people on the island waiting too long."

A few days later, Professor Xenius really pretended to be seriously ill and tricked his son, daughter and grandchildren into coming to the island. Then he began to appeal to their emotions and reason with them, trying to get them all to stay on the island.

Fortunately, his son, daughter, and their spouses were all biological scientists, just like Professor Xenius. Chen Yiran assigned them a task: to set up a laboratory on Lanai Island and continue their research into brain-computer interface technology.

Professor Xenius's reaction was the strangest. He seemed to have suddenly lost interest in the research and started coming to chat with Chen Yiran every day.

Chen Yiran looked helplessly at Professor Xie Nuoyi, who was staying at his house and refusing to leave, and said irritably, "Professor, if you don't leave, I'll let Pidan bite you."

"No, I've been here a few times and I already found out. Pidan isn't good at guarding the house. Don't worry, look how obedient I am now. I've even tricked the children into coming here with you."

Also, I'm very good at physics. You mentioned last time that you needed to brush up on your physics knowledge; I can help you with that.

"Is it possible that I learn very quickly and don't need anyone to teach me? Besides, aren't you a biology major? You also understand physics, right?"

Professor Xenius raised his head with a proud look and said, "Although you poached me from the Stanford Neural Prosthetics Systems Lab, I have a Bachelor of Science degree in Electrical Engineering from UC Irvine and a Master of Science and a Ph.D. in Electrical Engineering and Computer Science from MIT."

I chose to do research in the Department of Neurobiology at Caltech during my postdoctoral studies. I also learned some theoretical physics and related knowledge there. Although I didn't pursue a degree there, I have sufficient relevant knowledge.

"Okay, then tell me about the current cosmological hypotheses, the more prevalent ones in physics, and which ones also incorporate the concept of a multiverse."

Professor Xenius's eyes lit up: "Boss, before I got sick, I actually really liked this topic. After I got sick, I liked it even more, so I have some basic understanding of it."

Horizon multiverse, bubble multiverse, membrane multiverse, loop multiverse, landscape multiverse, quantum multiverse, holographic multiverse, simulated multiverse, mathematical universe hypothesis.

These are some of the more well-known ones. Which one would you like to learn about first?

Chen Yiran did not choose the membrane that seemed to best match his experience, but instead asked about another one first.

"Tell me about that mathematical cosmology hypothesis."

"Oh, this is the most elegant idea, and of course, the one with the least physical support. It was proposed by Max Tegmark, a cosmologist at MIT, who believed that the universe is a mathematical structure."

Elementary particles are identical and indistinguishable, like abstract symbols. The advantage of this theory lies in its perfect explanation of why everything conforms to mathematics, without needing to explain its origin, and through M-theory, it explains parallel universes; we are merely experiencing a mathematical possibility.

Professor Xenius talked on and on for more than ten minutes.

Chen Yiran scratched his head as he listened. Although he had become exceptionally intelligent after this experience and was not unable to understand these things, this bizarre way of thinking still made his scalp tingle.

"Stop, stop, stop, let's change to something else, let's talk about the brane multiverse."

"Okay, okay, this brane multiverse is the mainstream of string theory. It originates from M-theory, a unified version of string theory. String theory originally had five self-consistent versions. In 1995, Edward Witten proved that they were actually the same theory under different limits. This unified theory is called M-theory."

In simple terms, M-theory posits that the universe has 11 dimensions: 10 spatial dimensions plus 1 time dimension. The 3-dimensional space we perceive daily is merely a slice of these 11 dimensions.

In layman's terms, the universe is like a sandwich, with each slice of bread representing a three-dimensional universe, or membrane, and the jam layer between the slices representing a higher-dimensional space.

We live inside a loaf of bread, and can never leave it. But gravity can seep into the jam layer, so it's particularly weak within our loaf of bread. When two loaves of bread collide, the jam is compressed, resulting in a Big Bang.

"That makes some sense. Could you explain everything you mentioned before, one by one?"

Professor Xenius began to recount his previous mainstream cosmological views from the beginning, and when he talked about the holographic multiverse, Chen Yiran was deeply moved.

"The Holographic Multiverse, based on the principle of holography, was initially developed to solve the information paradox of black holes."

Einstein initially proposed the equivalence principle, which states that gravity is the distortion of spacetime.

The constancy of the speed of light causes spacetime to change depending on the observer's state, and gravitational waves, as ripples in spacetime, propagate at the speed of light. This theory corrects Newton's view, explains anomalous phenomena such as the bending of light and the precession of Mercury, and predicts the existence of black holes, completely revolutionizing humanity's understanding of gravity.

With the intervention of quantum mechanics, the vacuum is not absolutely empty, but is filled with virtual particle pairs.

Near the event horizon of a black hole, the separation of virtual particles causes the black hole to radiate energy outward and gradually evaporate—a phenomenon known as Hawking radiation. This leads to the information loss paradox, because quantum mechanics requires the conservation of probability; information falling into a black hole should not disappear, otherwise it would violate the fundamental laws of physics.

In 1997, Argentine theoretical physicist Juan Maldacena proposed the AdS/CFT dual, also known as the anti-de Sitter conformal field theory.

He believes that three-dimensional space containing gravity is equivalent to a two-dimensional boundary without gravity, which means that the information of the entire universe may be fully encoded on a two-dimensional surface, and the three-dimensional world is merely a projection of two-dimensional information.

In this way, the three-dimensional volume information inside the black hole is completely preserved on the two-dimensional event horizon, satisfying unitarity. This is the strongest support for the holographic cosmology, and a rigorous mathematical implementation and theoretical proof.

If we place it on the entire universe, that means our three-dimensional universe is a strict mirror image of phenomena occurring on a distant boundary. In fact, it is a boundary filled with two-dimensional information, something like a piece of paper or a membrane, each of which is a parallel world.

In fact, this theory has many implications for chips as well. One of the most direct corollaries of the holographic principle is the Bekenstein upper limit, which states that the maximum amount of information a physical system can store is proportional to its boundary surface area, rather than its volume.

This means that when the chip manufacturing process shrinks to the nanometer level in the future, and the transistor density approaches the Bekenstein limit, we can no longer increase computing power by increasing volume, because information density is limited by surface area.

It could be said that chip engineers are unknowingly approaching the core constraints of the holographic universe theory every day.

Chen Yiran thought for a moment: "If spacetime is a continuous 2-dimensional surface, it cannot fully encode 3-dimensional information. Therefore, the premise of the holographic principle is that spacetime is not continuous. At the Planck scale, spacetime is discrete, and the information density has an upper limit, which is why it can be perfectly dual. Is that what you mean?"

"That's right. It seems Mr. Chen has a deep understanding of physics as well."

After considering for a moment, Chen Yiran finally asked, "Let's assume, hypothetically, that someone gets slapped into a holographic universe, landing on the outer membrane. What would happen?"

Professor Xenius's eyes lit up: "Logically speaking, let's assume, let's assume, that someone, very impulsively, spends a lot of money and insists on using their exceptionally intelligent brain to try and disrupt the electronic world."

Then, instead of being copied to the computer, it inexplicably saw the truth of this world, and in an instant, it was separated from that two-dimensional membrane. It should then become a high-dimensional information that we cannot understand.

Of course, as you said, he was pulled back. In an instant, he was transformed back into two-dimensional information and then re-mapped into our three-dimensional world.

However, since he saw the membrane, shouldn't he be able to see something? He should be able to remember something, right? We should be able to understand a two-dimensional membrane, right? Let's assume he has feelings; what would he feel?

"Maybe he was too scared to see it."

"Oh dear, how could you do this, boss? I'm dying of cancer. I want to try uploading my brain before I die. Do you think that will work?"

"Fine, otherwise why bring your whole family to the island? Let your son upload it himself, and if there are any problems, it's none of my business. Let's go now, I have a headache, I need to rest for a while."

After Professor Xenoy left, Chen Yiran said to Jasmine in her mind, "So, is it possible that I wasn't reborn but transmigrated? The lower-dimensional beings along the way couldn't understand it, so they could only use the knowledge we can understand to come up with a reasonable explanation in their own minds?"

I'm more inclined to believe that we were originally part of this world, pulled out, wandered around in a higher dimension, and then were brought back. Therefore, I am your self-perception of that incomprehensible higher dimension.

"Forget it, let's not think about it too much. These are not things we can decide. Let's contact Musk. His progress is too slow. Let's give him a push. I feel like I'm seeing a lot of things on the membrane."
