I think I might have figured the double-slit experiment out. I am not going to explain it here, Google it if you don't know it. If I am wrong please tell me why:
Matter are relative to observers right (mass, time etc)? So let's for argument say there are 10 observers on earth.
When the particle leaves the gun towards the film, it will be relative to the 10 observers. Now the particle will exist in 10 states relative to each observer. If observers move faster than other, these states might even have different mass than other. So, because they exist in more than one state, they are actually different instances, one for each observer. So these states interfere with each other. That is why you get an interference pattern on the film from one particle, it is one particle in different states interfering with itself.
But what will happen when one of these observers observe it? He will only see one particle. He is not aware of the states relative to the other observers. Because there is only one particle according to an observer, the particle will act as one and the interference pattern will be gone. If it is not observed, it exist in relation to all observers. But according to an observer, there is only one. Think of it this way: Matter exist in relation to all observers, a state per observer. When you observe it, you can actually see the state relative to you. So by observing the particle coming through the slit, I can only see the state relative to me. But if I don't observe it, it exist in states relative to all observers.
Think of it this way: Let's assume there are only two people in the world. One (call him John) goes into orbit around the earth, he will be moving faster than the one (call him Matt) on earth. Now let's say he has a watch in his pocket. After 1 year he moved fast enough to lose 10 minutes relative to the person on earth. In John's reality 1 year passed, while in Matt's reality 1 year and 10 minutes passed. (We are already seeing this for satellites and is proven by experiment) For Matt the watch will be incorrect, while for John the watch will be correct (he experienced the same amount of time as the watch). Now the watch will exist in two states, one for each observer. In one state it will be 1 year old, in the other state it will be 1 year and 10 minutes old. When John observes it, it is in one state, but when Matt observes it, it will be in a state older. It exists in two states, same watch. Now when the two observers do not move much in relation to each other, it will still exist in two states, close enough to interfere with itself. That is why the particle interferes with itself. But when John see the watch, he can only see one. That is why I think the particle collapses back to one instance as soon as it is observed. It is basic relativity, I'll work on the equations, and post more on it.
To clarify: 1) Particle is not observed: It it exist in relation to all observers. These relations interfere with each other and cause a interference pattern, even though there is one particle. Up until it hits the film, it exist in may states, causing the wave interface pattern. 2) Particle is observed at the slit, so now it acts in relation to the observer that observed it. The interference pattern is gone because the detector and film is in essence the same observer, it forms part of the same experiment device. So the particle will only act in relation to the one observer.
So the question here is, does this theory conform to the scientific model?
