I understand that Shrodinger's wave equation describes the probability that a particle will be found at any certain location in space upon its observation. I'm wondering if these 'movements' adhere to the speed limit of light (and if so, why is this okay). For example, if a particle is observed right 'here', is it possible that it will show up half-way across the universe a split second later? I'm wondering because doesn't the probability wave theoretically extend out infinitely? Could the answer have something to do with the fact that the particle isn't actually moving through space (like how space itself can expand as fast as it wants)? Thanks for you time. Jeff.
