On David Bohm's ‘pilot-wave’ concept

We consider the interpretation of quantum mechanics on the basis of the so-called ‘pilot-wave’ concept from the point of view of its adequacy in the light of both already-realized and possible and gedanken experiments, including those that involve photons. It is shown that this concept, despite undoubtedly being useful, can hardly ensure compliance of quantum-theory predictions with the postulate that particle coordinates and velocities objectively exist, while splitting the wave function into empty and non„empty wave packets seems to contradict to the results of feasible experiments and their interpretations.
