Hey there. I'm not a expert in quantum mechanics, although have some experience with it, but I'm certainly far from being an expert when it comes to the pilot wave interpretation. For whatever reason, pilot waves have been mentioned quite a lot recently, and so I decided to take a closer look at it. I've seen many people claim that it makes the same predictions as standard quantum mechanics (Schrodinger equation, etc.), but I was pointed to this paper which seems to show that there is actually an issue with the predictions of the pilot wave theory: Deficiencies of Bohm Trajectories in View of Basic Quantum Principles Of course, it is possible that the people who have wrote this have made a mistake, but I don't have the ability to see it if it is there. Is this result not a serious issue for supporters of the pilot wave interpretation? Thanks in advance.
