Chapter 2606

"Roughly right." With a smile, Li Yun bent over and put his hand on the table. With his right hand, he hit a ball again and dropped the bag with a slap.

"But."

If you hit the ball from the wrong angle, you can feel everything in the wrong angle. Anxi, do you know the brain in the VAT

"Yes." Tang Anxi nodded.

This is also a famous assumption.

As we all know, the human brain depends on neurons to transmit signals. Among them, a kind of thing called nerve signal plays a key role.

And nerve signal is a kind of electrical signal, which means that human beings have the ability to imitate this kind of electrical signal, send wrong feedback to the human brain, and make the human body produce all kinds of illusions.

Including hearing, vision, smell and so on, can be simulated by converting electrical signals into neural signals.

Therefore, a crazy philosopher put forward such a hypothesis: if the human brain is put into a tank full of culture medium, and through various technologies, it can continuously give the brain false electrical signal stimulation, so that the brain thinks that its eyes see the world, the nose smells the smell, the hand touches things, and the temperature is sensed.

But in fact, the brain is always in the VAT.

This assumption raises a terrible question: how to prove that the world is real? Instead of being manipulated by aliens or gods!

In theory, this is an unsolvable problem, because the human brain has been completely controlled by false feedback, everything perceived is false, and in a false world, it is absolutely impossible to get correct cognition.

“…… We become brains in a VAT? " Tang Anxi looked around in surprise and even suspected that the clubs in his hands were fake!

However, if the world is false, the only real thing is definitely Li Yun in front of her!

"Who knows?"

Li Yun laughs and hits a ball: "that's why I said we should be calm, respond to all changes with constancy, and do things in the opposite way according to our usual habits."

"So it is!"

Tang Anxi finally realized that she was ashamed of her previous ideas. Li Yun had a good reason to do so. She had to break the habit of several days in a row to find the flaw.

"But No way Tang Anxi suddenly thought of something.

"What's wrong?" He Shao, sitting in the chair beside him, couldn't understand what brain in the VAT was. He had to search the Internet.

Tang Anxi looked at Li Yun with a pair of beautiful and divine eyes: "if we are in a fantasy world and everything around us is controlled - except Li Yun, why do people around us deliberately remind us that the time has passed? Let's have been emptied of our memory, and we will continue to do the "explore the ruins, return to the town, and continue to search for the ruins the next day."

"That's why I said to keep calm."

While playing, Li Yun said: "the other side either wants us to panic immediately. In fact, there is no time in the past few days, or the surrounding world is real, and the other side can't affect the people in the small town."

But there are still questions: for example, if the world is real, why did the other party let them have relics? Why did they return to the ruins the next day?
