Hi, I just finished taking my first look at some quantum physics material and need some confirmation on a point which was not clear within the material, which I think will be pretty easy for you to answer. The measuring of a particles position/momentum: If in theory a piece of apparatus existed that allowed you to measure the position of a particle without affecting its momentum, would you then be able to record these values with absolute certainty, and it is only due to this theoretical apparatus not existing (if it ever will) that means the uncertainty principle exists. Or is that there actually is some wierd universal law that exists that means no matter what is invented you are never ever under any circumstances able to know both values at the same time even if the equiptment existed that should allow you to do this ? As I said probably an easy question for most here, but I just wanted to get this answered before I go any further. Many thanks in advance for all answers.
