Chapter 2606 Brain in a Vat

"Roughly correct." Li Yun smiled slightly, bent over, put his hand on the table, and used his right hand to hit the ball again, and he dropped the bag with a snap.

"but."

Li Yun found another angle and prepared to hit the ball, "It is also possible that we have been in a fantasy world. Everything you see and feel is wrong. An Xi, do you know the brain in a vat?"

"I know." Tang Anxi nodded.

This is also a well-known hypothesis.

As we all know, the human brain relies on neurons to transmit signals, and one of them is called neural signals that play a key role.

The neural signal is also an electrical signal, which means that humans have the ability to imitate this electrical signal, send wrong feedback to the human brain, and make the human body produce various illusions.

Including hearing, vision, smell, etc., can be simulated by converting neural signals through electrical signals.

So, a crazy philosopher put forward this hypothesis: if the human brain is put into a tank full of culture solution, and through various techniques, the brain is continuously stimulated with false electrical signals, so that the brain thinks that its own eyes see the world, The nose smells the smell, the hand touches something, the temperature is perceived, and so on.

But in fact, the brain is always bound in a vat.

This hypothesis raises a terrifying question: how to prove the world is real? Instead of being controlled by aliens or gods!

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

"...We have become a brain in a vat?" Tang Anxi looked around in surprise, even suspecting that the club in her hand was fake!

However, if this world is fake, then the only real thing must be Li Yun in front of her!

"Who knows?"

Li Yun played a ball with a smile: "That's why I said to be calm, to respond to changes without change, and to do things in reverse according to our usual habits."

"So it is!"

Tang Anxi finally came to a realization. She was ashamed of her previous thoughts. It made sense for Li Yun to do so. She had to break the habit of the past few days in order to find the flaw.

"But... that's not right!" Tang Anxi suddenly thought of something.

"What's wrong?" It was He Shao who asked the question. He was sitting in the chair next to him, and he couldn't understand what a brain in a vat was, so he had to search the Internet.

Tang Anxi looked at Li Yun with a pair of beautiful eyes: "If we are in a fantasy world, and everything around us is controlled—except for Li Yun, why would the people around us deliberately Remind us how many days have passed? Wouldn’t it be better to let us keep emptying our memories and keep repeating ‘explore the ruins, go back to the town, and continue to search for the ruins the next day’?”

"That's why I said keep calm."

While playing, Li Yun said: "The other party either wanted us to panic immediately, but in fact, there was no time in the past few days, or the surrounding world was real, and the other party could not affect the people in the town."

But there are still questions: For example, if the world is real, why did the other party let them out of the ruins? Why did they return to the ruins again the next day?
