stevendaryl, vanhees71, Demystifier, atty and others well verse in Bohmian mechanics and know the ins and outs or the basic. Some questions I'd like to ask. 1. What would happen if Bohmian Mechanic is not inherently random, for instance.. if the trajectories or initial conditions were controlled by another field that is inherently random.. is it still called Bohmian Mechanics? (if not.. how come?) 2. What would happen if there was no trajectories but QM particles have substantial (or ontological meaning "really there") existence that can appear and disappear. Would it still be called Bohmian? I am thinking whether substance or ontology is the essence of BM? 3. What main features of BM make it distinctly BM then and what experimental signatures to look for (trajectories or substance for example)? Thank you!
