Hi,
I'm reading that a particle located at any given point can, in the next moment, be at any other given point in the universe. My understanding is that this is a correct interpretation of quantum physics.
So, my question is, how does the particle 'decide' where actually to be in the next moment, and why there rather than anywhere else? My current understanding is that it has something to do with the path of least action, which I've interpreted as it takes the 'easiest' route between the two points.
Assuming I'm correct so far, does this mean that the particle does NOT actually go to every point in the universe (even though it has to potential to do so), but actually only goes (or 'contemplates' going) to a relatively few points in the nearby area, which provides it with enough information to then 'know' which path is the 'easiest' to take?
My understanding is that this is similar to all the possible routes I could take on a trip from my house to the shop at the end of the street. I could get to the shop via Pluto or via a galaxy billions of light years away, but I don't, because I only have to contemplate walking a greater distance from the shop in the opposite direction before I give up on that path and go a shorter route, excluding my trip to Pluto from my plans. Would it be correct therefore to say that particles are efficient?
Am I totally confused? Thanks :-)
