Hi all, I've recently been reading a little bit about pilot wave theory (as a physics novice). It's an interesting interpretation of quantum mechanics, but I'm wondering (apologies that this is in very non-technical terms): I can understand how the pilot wave interpretation leads to same results as 'standard' quantum mechanics for, e.g., the double slit experiment, where an ensemble of trials will show the expected interference pattern. But isn't it also the case that a particle should with some probability spontaneously transition to form other particles (e.g., a photon spends some time as an electron-positron pair)? That is, as discussed at, e.g., http://www.scientificamerican.com/article/are-virtual-particles-rea/ From the above article, "quantum theory predicts that every particle spends some time as a combination of other particles in all possible ways." Isn't this type of occurrence essentially random, and if so, how does the pilot wave interpretation deal with this? Thanks. J.
