Hello guys, I made this analogy for double slit experiment. I would like to share this idea and I would like to hear your opinions and ideas. Thank you. I apologize for any typos or bad grammar, I am not native english speaker. Here it is: Analogy for wave collapse I am using term KNOWER instead of OBSERVER because delayed choice quantum eraser has shown us that not act of observing change the outcome, but very knowledge of which path information does. Imagine we ask a random person a question we know the answer for, but he does not. We will give that person two options (A or B), both equally like to be the right answer. If the person doesn’t know the right answer, it means that both the answers (A and B) can be the right one. In other words, THE RIGHT ANSWER is in superposition of two states (A and B). When we tell to the person which answer is the right one (let’s say its answer A), it immediately causes collapse and leaves to the person only the one right answer. Answer B is no longer right, it collapsed to category WRONG ANSWER. We represent a particle A person represents knower Two options represent double slit Not knowing the right answer represents wave CONCLUSION: As we know which answer is the right one right from the beginning, is is obvious that superposition does only exist in relation to knower. The right answer has been always only one. Having more than only one option to answer creates possibilities, but it doesn’t mean that there is more than one right answer at the same time. This might also explain retro causality. It’s exactly the opposite. It is not that person who finds out the right answer immediately tells us which one is it, we had known the right answer beforehand. Particles had known the outcome before which path information was obtained. IN CASE OF QUESTIONS ABOUT DELAYED QUANTUM ERASER: this way we can imagine we use a machine to record the right answer and pass it to the person without yet hearing it. The outcome is already set. If the person destroys the record machine, he has still a wave of possibilities A or B to be the right answer. If the person hears the recorded answer, it gives him only the one right answer. As to explain how the particles can know the WHICH PATH information before they are actually sent into slit, I dont have an answer for that. Especially difference between quantum mechanics and classical physics. As if in a quantum world, a person hearing a question always either know or not know the right answer, whether in macro world hearing the same question means you know the answer immediatelly.
