I know an electron when not interfered with after leaving it's source is not really in any space. It just has a probability of being in various places, it isn't real yet. But how do i visualize how that happens? Let's say over 500 million planck lengths in a vaccuum. Does the probability move like a wave from where it left to the wall? Let's say it moves 90% light speed, so it would take 450 million planck time units to get to the other side (this is average right?, almost never precise, even when distance would be precise. It would be purely random how many planck time units it would take, if it would take longer it would arrive with more energy, and if it would take shorter then it would arrive with less energy?). Would the most likely place to find after 225 million time planck units exactly (or roughly, but still relatively precisely) be in the middle of this box with the lenght of 500 million planck lenghts (so at 250 million planck lenghts)? Would the peak of this probability wave (so where it is most likely to be) move from where it left to the other side of the wall in a linear fashion, sort of like a regular sound or water wave? How do i visualize how these probabilities move in time? Same with after you would 'intercept' this electron half way through. The superposition would collapse, and it would move as a particle. Does that mean the quantum weirdness dissapears, or simply that the probability wave becomes very narrow? And after the observation the electron goes back to it's quantum weirdness? Except in a very narrow wave form so it looks as if it behaves as a particle now. Finally how much would the width of this space matter (still with the same 500 million planck lenght unit lenght as before)? Would it make a big difference if it was also 500 million planck lengths wide, or let's say 100 billion planck lenghts wide? Im still really bad at math, so i find it hard to extract this from the equations yet.:) Thanks in advance.
