Hi, my first post here so be gentle with me :) Firstly I have no background in physics other than watching the sky at night so any complex mathematical explanations will be lost on me, I'm just looking for an intuitive way to understand what is happening in a system that's quantized. All my attempts at figuring it out end up in contradiction. If an electron can only exist in discrete orbits then how does it actually "get" from orbit A to orbit B, I assume that if it can only exist in certain orbits then it cannot be moving from one orbit to the next through space I also assume there must be some sort of delay between jumps or it would violate the limitations of speed c. If my assumptions are correct and it cannot physically traverse the gap to a different orbit and it cannot jump instantly then it must vanish for some length of time and then re-materialise. Is it absorbed by the vacuum and then and then re-emitted at a different location? If it does vanish does that mean that for a tiny instant the atom becomes a different element? Or is it just that this phenomenon cannot be expressed in in any other way than mathematics. Any help putting me on the right track appreciated.
