I find quantum theory fascinating, because it fundamentally changed the perception of science. Before quantum theory everything was definate, things had a definate position, things interact in a definitve way, but quantum theory does away with all of that by saying that the most accurate model we have is not a definitive, but instead assignes probabilities to them. So here we have a theory that is extremely concepually puzzling, but it is one of the most powerful tools to predict things science has ever had in its hands, so it can not be ignored, no matter how puzzling it is. I dont understand what chooses these probablilities to make them definate. For example, time reversal symetry should mean that milk jumps out of coffee just as often as it dissolves into it, that people get younger looking as often as they get older looking, we can influence the past just as much as we can effect the future. All of that is wrong, and comes into violent conflict with how we psychologically view the universe. What process chooses the potential probabilities of quatum mechanics, and makes them the definitive world we observe? thats what i dont get, it seems as if quantum theory leaves this area open to intuition and interpretation rather than actually explaining what chooses these possibilities to form what we observe.
