Our world may already be deep in the metaverse

In the past few days, everyone is discussing the metaverse again, probably because Facebook changed the company name Facebook to Meta, which means taking the meta in the metaverse. Some people think this is a big move, and think that the way of human existence may really be changed. Some people think that this is leading the way, so where can the metaverse lead mankind? It will really lie in a game cabin like in a sci-fi work. And then spend your life in a virtual universe? If that's the case, it doesn't seem to be any different from a brain in a vat.

All perceptions experienced by human beings are neural signals received by the brain, including vision, hearing, taste, touch, and smell are transformed neural electrical signals, and then handed over to the brain for processing. So in theory, put the brain in a petri dish and transmit various neural signals to the brain, and the brain will think that it is in the real world. Putnam, who proposed the brain-in-a-jar hypothesis, wrote in his book That being said, a man was operated on by evil scientists. His brain was cut from his body and placed in a tank filled with nutrient solution. The brain's nerve endings were connected to a computer.

The computer is programmed to send information to the brain, giving it the illusion that everything is perfectly normal. For him, people, objects, and the sky all exist, and their own movements, bodies, and feelings can all be input, and then the brain can also be input or intercepted. For example, delete the memory of this person's brain surgery, and then use Instead of everyday life, he could even be typed in a code to make him feel like he was hearing something funny and absurd right here right now. Finally, the author asked a question that no one has been able to answer clearly so far, that is, how can we be sure that we are not in this predicament?

If all the information processed by the brain is neural signals, then no one can know whether such signals can be copied, so humans can't even confirm whether they are in the metaverse, and now they have created their own metaverse. The universe is over, is there really an invisible law in this world that needs to develop down layer by layer? If we look at the model of human beings, that is, the model of human beings creating the metaverse, if we want to distinguish whether we are in the metaverse or not, we need to see if the world we live in has experienced lags or bugs. If such a situation has ever occurred, then it is also a possibility that humans are in the metaverse. One phenomenon so far that has always felt like a human metaverse server failure is the Mandela effect.

We know that each country's news reports will have their own traditions. The same thing may be different in different countries' news, including a slight deviation in translation in different languages. However, for former South African President Mande A strange phenomenon appeared in this person. In the memory of a large number of people, Mandela passed away in the 1980s. This large number of people came from all over the world. How did they know this news, of course, through The media, but as mentioned earlier, the media have different traditions, and they should be more rigorous about the life and death of politicians.

If there is no basis for such a fact, why do people in so many countries remember it wrong? The first person who proposed the Mandela effect was American Fianna, but there are people in China, Russia, Japan with different cultures, and Europe far away from the United States, there are people who have such memories. So when South Africa held the World Cup later, there was news of Mandela, I felt very surprised, but the feeling at the time was just an accident. Then it took years to find out that so many people around the world have memory biases, so it's really hard to explain. Many people are willing to interpret this phenomenon as group memory bias, which means that the brain processes some information by itself and clarifies some vague events. Obviously, I cannot accept this statement.

So instead of saying the phenomenon of the Mandela effect is that the brain processes the information on its own, it is better to say that some brains in the population simply receive it. Different information is like the restart of the universe server, or the intersection of parallel time and space. The server downtime will cause some players' data to be lost. After recovery, the memory data will be inconsistent with other players, resulting in group memory bias.

The intersection of parallel time and space is like a combined area in the game, the same map scene, the same main task, the difference is that the players in the two areas of Yuanben are merged together, and the data is exchanged, which will also produce group memory bias. , so both the server downtime and the intersection of parallel time and space point to the point where humans are in the metaverse.
