Are there other realities?

 Are there other realities? 

When we are talking that reality can be the sum of all existent realities we must ask: is there some other realities than the reality where we are now? Reality is always a unique experience. But then we must realize that there is one remarkable thing in the human brain. 

The human brain can work in superposition. That means that we can do and think about different things. We can cook food and think about mathematical formulas at the same time. So in that case, we have two states in our brains. 

That means our way to realize things differs from dogs and other animals. Animals have only one state in their brain. They live here and now. In the human brain, the second state allows us to think abstract things without risk. The ability to think abstraction makes us unique. 

But if some animal starts to think about abstraction. That means the animal slides out of reality. And that thing puts our animals in danger. Because the human brain has different layers. Those layers can make many things at the same time. But if we do something the first time we must concentrate on that thing. 

Then we must understand another thing realities that we can observe might differ from realities that affect us. Reality and existence are things that are almost the same thing. The object can virtually exist. While a person sleeps those virtual objects turn into reality. They exist only to that person. Existence is a strange thing. 

We know that theoretically, a nightmare can kill a person. The emotional feeling or feedback from the nervous system can cause the situation. Where a person who has a weak heart can die because of nightmares. Because a person cannot separate reality and dream. That can cause a heart attack.

Can virtual reality turn real?

Sometimes people are asking can 3D virtual reality computer games turn into reality. Theoretically, we can think of the situation of those gamers of the game trapped in the electric chair. 

And if the character in the game dies, that launches an electric chair. That is the thing that can turn virtual reality into reality. That is one version of the thinking experiments. 

***********************************

Ants see reality differently than humans. In this case, the question is does the ant realize, and does it understand what it sees? And does reality require that actor realizes what the actor sees? This is an interesting question. Consciousness doesn't necessarily mean that actor realizes what the actor sees. 

When some insects see that something tries to slap them, it jumps away. So does the insect understand what it does? Maybe someday we know the answer. The fact is that reality is not the only certain thing. Things like hallucinations in mind. And 3D worlds in computer's memories are also reality. But they are not reality the same way as some forest is. 

Is reality exists?

Is reality exists? 

Does the subjective experience make reality more or less exists? In some models, reality forms in the future, and at the point where we and time flow crossing, reality turns things that we can observe. Everything that we see happens in past. The time that photons take to travel from 200 meters away is minimum. But even in that kinds of cases, we see things that happen in the past. Things like fog and other disturbances affect information even in a short moment. 

The information that we get is not identical. The position and other things between two observers affect their way see things. Different experiences also affect people's feelings. And those things affect the way to see a thing. When two people are standing near some object and another of them has a strong negative experience connected with that object, that person sees it differently than the person whose experiences are neutral. 

Reality is a subjective experience. 

Reality is one of the things that we don't know. We know that something exists. Things like electrons are well-known things. But we cannot see that thing. We read those things from the net and books. 

Things like our personal experiences are modeling our relationship with reality. When we see something we cannot be sure, does some other actor got the same feelings about it? All our senses participate in forming of reality that we sense. But there are different ways to see things. 

In some models, reality is an illusion. That is formed in our brains. We know that absolute reality does not exist The position and senses of the observer determine how we see reality. And the ability to communicate between observers also limits sharing of information. If we are not telling everything to another person something is missing. 

So how can we say that another person feels and sees things the same way as we see them? And even the best description cannot transmit the entirety of our feelings to another observer. Full entirety means that we can transmit also things how we feel about those things. Sense of touch and sense of taste is hard to describe. That means we cannot feel and taste everything the same way. 

The AI can answer questions. But it doesn't realize what it answers. 

That thing makes AI problematic. If we ask for something kinetic or absolute from the AI that thing can tell many things about that thing. Kinetic things are like the technical details of Formula 1. The AI can tell colors and engine horsepower. But things like opinions, for example, which one is better, chicken or vegetable hamburger, or do you like heavy metal or classical music cause problems to AI. The reason for that is that AI doesn't have an opinion. 

The AI can say that it cannot tell opinions. But the problem is that the AI follows algorithms. Algorithms are program codes that describe how the AI must act in certain situations. So if the AI doesn't recognize the question about opinions it can start to find the answer from the net, by using certain parameters. And one parameter can be which pizza or which music gender is higher in order or listen to list. 

So the situation is similar as we will ask people which is the best hamburger, and then we can say that the best hamburger is the hamburger that is the most often bought. In that case, we can make elections and vote on many things, but that thing doesn't tell anything about our personal opinions about that question. 

The fact is that the AI cannot detect if the information is false. If somebody hijacks the sensors that the AI uses that thing means that AI cannot detect data coming from the camera or some other source like a high-resolution screen. 

There is no true or false data. There is only data. 

When we handle data. We must realize that our brain doesn't know if data is true or false. The thing is that data itself is just data. That means our brains and consciousness don't automatically suspect data is false or true. These kinds of processes are the result of training. 

When we see the object created by using a hologram machine, we can say that the object exists. It exists as a hologram. In that case, we have no responsibility if we describe the object as reality. If somebody introduces a hologram as a real object. And we cannot touch it. We have the right to believe that object is real. 

There are two images in this text. I took those images in the same place and the same place. The focus in those images is adjusted differently, and that makes those images different looking. The purpose of those images is to demonstrate how the difference in senses affects how we see reality. 

Lots of existence is out of our ability to observe it. 

An object is a reality in the form of a hologram. As I just wrote. But then we must realize that the reality. What we see is only a small part of our existence. We see only a shell of material. Nobody has ever seen the nucleus of the atom without extremely advanced systems. Same way as we see only a small part of icebergs. We see only a small part of the electromagnetic spectrum. 

So that means there are lots of things that we can never observe without equipment like infrared or X-ray telescopes. Every year we find another part of reality. Reality does not exist in absolute form. We know that we see something, and the same way things, like insects, see something. But then we must ask: does the insect realize what it sees? 

In the insect's brains is two modes: hit or run. If an insect sees something it recognizes the object. If the object is food or a partner the insect goes near it. And if an insect sees something else it escapes. But in our brains is many other possibilities. Reality is something interesting to us. We might see many things, but because we don't always react outsiders cannot see, what we see. And another thing is outsiders cannot see how our brains modify things that senses bring to the cortex. 

Plato's cave is an example of selective information. 

Plato's cave is an example of selective information. Or brains are always selective because their capacity is limited. And they select things that they store. Everything that happens to the carrier of those brains happens just to that individual. 

This is the thing that makes every experience unique. If we see that some other person falls we cannot feel that thing in our own body. That's why we always react differently to things that happen to somebody else than we react to things that happen to us. This is why all experiences are somehow subjective. 

Reality is always subjective. If we would spend our entire life in some room and VR (Virtual Reality) masks are on our faces, and we ever go outside. We can think that reality is what we see on those screens. If we spend all our lives in one room, we can think that everything is like in that room. That room is our entire world. 

We can make that room a virtual reality without any VR systems. If we ever can go outside and we cannot see anybody else than some servants, all the information that we can get depends on what those people are telling us. 

The fact is that this is a high-tech version of Plato's cave. In that model, somebody controls everything that we see. The Internet could be the big Plato's cave if we just search for information that pleases us. If somebody covers the entire planet by using screens that allow that actor to deny that there are no other things in the universe except that planet. 

The thing is that even the biggest of Plato's caves are. Places where people get subjective information. People who use the internet are easy to blame for that thing. But even if we travel to distant countries we can select the information we want to see and feel. We can go to some country and then sit in a taxi or tourist bus and spend all time in a hotel. Would we get the right or diverse information about the country?
