Sometimes I feel like I should have been a physiology major rather than a physics major. I spend so much time analyzing my own mind that I kind of wish that I has a little something to back it up. I find it incredible that we can know so much about the world around us and yet know next to nothing about how the human mind works. It does not make sense. The one tool that we use to understand what is around us is something that we understand very little about. Now I must say that we probably understand the brain better than a number of things, such as some of the more complicated physical phenomenon that result in a break down in space and time. I wish that I understood the way that my mind works I feel that it would give an incredible understanding of the way that I observe the world around me.
If you think about the observer of an experiment some interesting things come out of it. There is the whole this about Cat states and wave function collapsing when a system is observed. In all experiments that I have ever done seen or heard of the observer is never mentioned. It is simple assumed that something that has the ability to make logical constructions about abstract thoughts. In other word the observer can see and knows that it can see but this is the extent of the ability of the observer. But now let’s say that the observer is the experiment. What happens then?
Take the famous cat in the box. We are going to have to modify this a bit so that the result of particle hitting the detector does not kill the cat it simple dumps a bucket of water on it. This must be done because if the cat dies then it no longer knows that it exists. This is all assuming that the cat knows that it exists and can tell when it is wet. I feel that I can make this assumption because well cat hate being wet and the amount that they lick themselves I would hope that they realize that they exist. Not the experiment is run and the cat is either dry or wet. The cat knows which it is or the way that we view the world we would assume that the cat knows that it is wet or dry. But according to the rest of the world the cat is in a wet dry state. Where there is an equal probability that the cat is wet to dry and nowhere in between. According to the outside world the wave function has not been collapsed but the cat is wet or it is dry and the cat knows.
So what does this mean? It means one of two things. That either reality is relative which just sounds funny or that there is no such thing as reality and that it is simple a construct of the mind trying to survive. The first of these two is an interesting one that I have not thought about all that much. The idea of relativity is a wonderful thing. Those of you who have taken even an introductory class on the subject know this (ha). It is one of those things where reality is different from different reference frames. This fits perfectly with the idea of the cat being wet and dry but it is based on an entirely different experiment (a massive body chasing a photon, ha good luck). It is interesting that two ideas come to the same conclusion.
I feel that much of what I say depends on definition (like every other thing in this world). If you define reality to be a rigid body that is always the same everywhere you go then both the light experiment and the cat experiment shatter this rigid reality. However if you take reality to be flexible (put yourself in other people shoes every once and a while), then both of these experiments fit just fine. So what then does this all mean? Nothing really, just confirming the fact that if you do not look at things from another point of view then your reality is going to break at some point. And nobody wants reality to break.
I kind of cheated. I said that there were only two possibilities when there is really a crap stack more. I just chose the two that proved my point the best. Physicists love doing that. And I love this unknown observer that I have chilling in my dome.
