I lifted this from Wiki which I had not read before but probably is what I am saying...sort of maybe
http://en.wikipedia.org/wiki/Virtual_particle
The bit I noticed there was......
Many in the scientific community view them as an ad hoc abstraction that is required because our current view of reality as described by quantum mechanics is not complete. It is thought by this segment of physicists that virtual particles will no longer be required when a more complete view of quantum mechanics is integrated with general relativity and gravity in general
That was not where I formed my idea that particles dont pop in and out...
I will try and find that ... to refresh
