Are Bohmian pilot waves located inside spacetime? Or is it independent of the Lorenztian metric? What are the constraints or possibilities? What is the pilot wave connection to the vacuum. We have heard such a thing as false vacuum. Could pilot waves be located in a false vacuum? If this false vacuum separates itself from our vacuum... could pilot waves located in the false vacuum be composed of magnetic monopoles? Or are pilot waves completely substanceless? What are the mainstream belief and theoretical possibilities that make it consistent with the predictions of quantum mechanics?
