Should We Interpret Quantum Mechanics According to Bohr

I present here a thought experiment which violates the most widely accepted interpretation of quantum mechanics “The Copenhagen Interpretation” and Bohr’s complementarity which says that there is no meaning of the state of a particle until it is observed and the act of observation might change it. The experiment consists of a double slit apparatus which is modified by putting a second double slit apparatus between the source and the original apparatus with certain conditions imposed on both the apparatuses using the facts of interference and diffraction. A striking paradox emerges if we consider the arguments of Bohr’s complementarity, i.e. the photon travels through both the paths simultaneously in a double slit apparatus whenever there is interference. It turns out that this paradox can be resolved only if the photon travels through one path even if interference fringes are visible.
