If it is true that due to energy fluctuations of a vacuum being able to produce a particle-antiparticle pair that shortly annihilate with each other and disappear again, is the following circumstance possible?
I was then thinking that if this was the case, there would be some inherent uncertainty to any particle's position, because of the particle/antiparticle production in vacuum was random, then if I leave an electron in a specified place for a short period of time, the pair production could have caused the electron to move. This seemed to fit in really well with the concept of a wave function, and that we can never predict a particle's position with 100% accuracy, and to me this seemed to offer some sort of an explanation as to why this was the case.
The only knowledge I have on this topic is knowledge gained through pop-science, and so I don't really understand much of this at all, so any help understanding would be great. I talked to my friend about this, and he said something along the lines of "the pair production particles aren't 'real' particles, and they can't really interact with anything", though I'm not too sure I understand what that means.
