I sincerely apologise if this has been asked previously, I searched via Google and have been unable to find an answer I understand. How does the de BroglieBohm, or Pilot Wave, interpretation, well interpret virtual particles. The beauty of the deBB interpretation seems to be the unity of the quantumworld and the everyday world (no magic observation mysteriously collapsing an superposition, or splitting the multiverse), but virtual particles seem so indeterminate that they provide, in my understanding, difficilty for deBB.
If it helps you gauge the level of answer to give I studied physics in the UK until 18, and my university education was largely in medical biology. Though equations are appreciated for sake of completion...i doubt i will do any more than partially understand them.

deBB is an interpretation of the formalism of nonrel. QM. Virtual particles are a name for some mathematical aspects of an approximation (perturbation theory) of full quantum field theory QFT). Neither is deBB complete (not applicable to QFT) nor is the picture of virtual particles complete (limited applicability of perturbation theory).
You should not try to infer an interpretation of a limited formalism based on another limited formalism.

Thankyou,
As I understood it QFT is an attempt to unify describe what happens to the laws of quantum physics when combined with relativistic laws, am I oversimplifying, or mistaken? Aren't there attempts to produce a relativistic version of deBB? If so do these attempt to define virtual particles? I apologise if the answer is again that the interpretation is too incomplete to make an viable description. The copenhagen explanation seems, in layman's terms, to be vacuum energy is subject to heisenberg uncertainty, virtual particles can arise for a short time, indeterministically, at random. Is this due to the Copenhagen Interpretation being more developed than deBB?

Thankyou Mr.Nikolic, I will attempt to understand what you have written and then attempt to ask an intelligent question and less than 2 stupid questions.
