The Schrödinger's cat and the question of the existence

Sometimes people are thinking, what kind of thing could be the real world Schrödinger's cat? The cat is closed in a box, where it cannot straight interact with us, but we can see the cat. If we try to get the cat out it will exterminate, and that cat has caused a question about existence. Is the thing that cannot interact with us some mean to us? Does the thing that doesn't interact with its environment exist? 

When we are thinking about abstraction the things like thinking is existence we might ask are our thoughts exists or not? Thoughts and the ability to create synthetic models, the abstraction in the brains are making us humans. The ability to make models are making humans the most dominating species in the world. Are thoughts exists or not? Even if we are not telling those things to somebody else, those thoughts affect us. 

Why we don't have full control of our thoughts? Why we are thinking so uncomfortable things? The fact is that this thing is made for protecting individuals. The reason why we remember bad things better than good things is easy to explain. Those things are made for protecting people against dangerous situations. If somebody yells at us we remember that thing, because that person can be dangerous later. So that thing we are remembering nasty customers better than nice customers. 

We know that other people are not seeing the existence of our thoughts but for us they are real. The thought is things, what is forming from our experiences, history, and other things, what we might want to feel and see. Many people have great ideas, and some of them are the most intelligent people in the world. But the problem is how to confirm that those ideas and thoughts are those people's own? The fact is that if some people are only thinking. 

But they are not telling their ideas to others, how other people can see, how intelligent those quiet geniuses are? How to confess to other people that the thoughts that people have are good or bad? Or they are good for bad? Making the thought to real innovation is something, that we are always afraid of and hope for. We all want to be great inventors, but we always want to stay in grey mass. And at the first, we must realize that there are no meanless innovations and inventions. 

The helmets that are washing teeth of the people might seem funny, but what the astronaut who is working in the spacesuit would do with the system, what washes teeth? Or what the astronaut would do with a small robot hand inside the helmet what puts the drinking tube to the mouth if that thing slips out the mouth? And what the same person would do with a small hover what is sucking things like vomit out from the helmet? 

Or what the military men would do with springs.  That is connected with bulletproof west for making the impact softer? Those things are extreme places, but there are always things that are turning useless useful. Who would think someday that things like gravitational waves have something to do with everyday life? 

Things like quantum computers, where superpositioned and entangled photons are transmitting data are causing scenarios, that the gravitational waves can destroy the entire system. So is it possible that someday in the future there are warnings about the gravitational waves? Gravitational waves might seem meanless but are causing a threat to quantum computers by pushing the positioned photons.
