In the past, Bohmians are a minority and more of a curiousity or side show and even now although it's getting more popular. But thinking it over and over. The alternatives are quite stranger. In Copenhagen for example. Do you actually believe that the interferences don't actually occur physically but only in the equations (implications is we live in the equations)? In Many Worlds, do you believe that in your trip to office, you spawn hundreds of universes? These two don't quite add up and believers are more into the all powerful feeling of it. Bohmian Mechanics seem more like common sense after thinking of this over and over. What are the challenges facing Bohmian mechanics now? What are the disbelievers greatest critiques of it? Is it compatible with quantum gravity as in Bohmian quantuam gravity? Is Bohmian lorentz invariant? What present physics concept have to be eliminated or sacrificed to accomodate Bohmian Mechanics? What is your personal critique of it possible or negative?
