Right I am going to go out on another limb something I have been thinking about.

Right if an electron cloud exists "now" then could it be possible by quantum tunneling for an electron to pop into the future or into the past and visa versa for as long as the universe has expanded and is going to expand for this would then cross over to multi verse models of the universe we are in?
