The Ontological Interpretation and Bohmian Quantum Theory of Motion

According to the orthodox interpretation in quantum mechanics, the spatio-temporal properties of a physical thing cannot be defined before measurement. However, it is obvious that physical things exist even though nobody sees them. Indeed, there would be no concept, whether physical or psychological, without an external public object whose existence did not depend on the measurement process or observing consciousness. Fortunately, Bohm proved the idea that a particle has a continuous trajectory in phase space is compatible with the standard formalism of quantum mechanics. The virtue of the Bohmian quantum theory of motion is that it saves our common sense ontology.
