| I will use word 'interaction' instead of 'observation'. We are very limited by language we use, so picking terms we use to describe certain phenomena is very important. We can't always pick the best one, some things can't be easily described. That's why we have abstract tools like math to approach this. Observation happens and ends. Interaction can lead to another interaction, leaving more degrees of freedom and possible states. I imagine underlying fields being and interacting in such way that it defines quantum properties of particles and their further interactions. Everything is chaos, it just depends on which side of chaos you happen to be. When particle interacts with something else (other particle) fields produce interaction based on previously collapsed chaos, other interactions follow further collapsing chaos in a tree (branching like) structure. What we describe as our reality is a result of a sequence on interactions, a collapse of infinite probabilities into a single sequence as governed by underlying structure of fields. When you look through the window what you see is what is one of infinite number of possible realities. You see the one that is allowed by underlying quantum field structure. |
