Chapter 2632: Brain in the Tank
"Roughly right." Li Yun smiled slightly, bent over and leaned over, with his hand on the table, with his right hand, he hit a ball again, and dropped directly into the bag with a snap.
"but."
Li Yun looked for another angle and prepared to hit the ball. "It's also possible that we have been in the illusion. Everything you see and feel is wrong. An Xi, do you know the brain in the tank?"
"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, of which something called neural signals plays a key role.
The neural signal is also an electrical signal, which means that humans have the ability to imitate this electrical signal and send wrong feedback to the human brain, causing the body to produce various illusions.
Including hearing, vision, smell, etc., can be simulated by converting electrical signals into neural signals.
Therefore, a crazy philosopher put forward this hypothesis: If the human brain is placed in a tank full of culture fluid, through various techniques, the brain is constantly stimulated with false electrical signals, so that the brain thinks that its eyes see the world. The nose smells the smell, the hand touches something, the temperature is sensed, and so on.
But in fact, the brain is always bound in the tank.
This hypothesis raises a terrifying question: how to prove that 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. In a false world, it is absolutely impossible to get correct cognition.
